The Portuguese Companies Code (CSC) sets out the various types of commercial company recognised under Portuguese law:

• general partnerships (sociedade em nome coletivo);
• private limited companies (sociedade por quotas, or Lda.);
• joint stock companies (sociedade anónima, or S.A.); and
• limited partnerships, simple or by shares.

Of these, the most common in Portugal are Lda.s and S.A.s. Business is also carried on through:

• branches of foreign companies (sucursais), which have no separate legal personality;
• sole traders and co-operatives; and
• the complementary grouping of undertakings (ACE).

In an Lda., the share capital is divided into quotas, and the company will generally have at least two shareholders. There is no statutory minimum capital, which is freely fixed in the articles subject to each quota having a nominal value of at least EUR1, and the company may have a single quotaholder (sociedade unipessoal por quotas).

Shareholders are jointly and severally liable for the agreed contributions, but creditors may look only to the company’s assets. This makes the Lda. the preferred vehicle for small and medium-sized businesses.

In an S.A., the capital is divided into shares, each shareholder’s liability is limited to the shares subscribed, and shares are freely transferable subject to legal or statutory restrictions. Except in specific cases provided for by law, S.A.s must have at least five shareholders and a minimum share capital of EUR50,000.

Portugal does not recognise trusts as a domestic legal institution and is not a party to the 1985 Hague Convention on the Law Applicable to Trusts. A foreign trust is not void in Portugal, but it will generally be looked through for Portuguese tax purposes and cannot be registered as the owner of Portuguese assets. A comparable result is usually reached through a holding company or a foreign law fiduciary arrangement.

Choice of form is driven as much by governance requirements, tax and disclosure as by liability.

In Portugal, a company may be incorporated either through an online procedure or in person at a Commercial Registry office. Incorporation may also be carried out via Empresa na Hora (incorporation within an hour), which allows the shareholders to have the company incorporated on the same day, using pre-approved template articles of association issued by the Commercial Registry. Where the articles are bespoke, or where powers of attorney, apostilles or an auditor’s report on a contribution in kind are required, three business days is more usual.

The company name may be chosen from a list pre-approved by the Commercial Registry. The share capital may be deposited before incorporation or, in circumstances permitted by law, within five business days thereafter, or by the end of the company’s first financial year.

The online procedure is now the most commonly used method of incorporation. Where a pre-approved template of articles of association is used, the cost is EUR220 for standard applications, with urgent applications charged at double that fee. Further costs may arise on name reservation, bespoke articles, notarial authentication and activity licences.

Following incorporation, companies must comply with a range of corporate, accounting, tax and registration obligations. A beneficial ownership declaration is also required, as described in 1.5 Control Person Reporting. The annual accounts and the management report must be approved within three months of the financial year end, or within five months where consolidated accounts are prepared. Before trading begins, the company must also open a bank account, enrol with the Tax Authority and with Social Security, and appoint a certified accountant, together with obtaining any licence specific to its activity. Every shareholder, director and attorney must hold a Portuguese taxpayer number in advance, and a person resident outside the EU or EEA must appoint a tax representative, unless he or she adheres to the Tax Authority’s electronic notification channels.

Companies must maintain organised accounting records under the Corporate Income Tax Code and the accounting standards, overseen by a certified accountant, and must submit annual income statements with the relevant accounting and tax information. These filing obligations include:

• the annual accounts, once approved by the shareholders;
• the Simplified Business Information return (IES);
• corporate income tax returns; and
• periodic VAT returns.

Share capital rules are set out in the Companies Code. The articles must state the capital in euros, each shareholder’s contribution and the payment deadlines, and contributions in kind require appraisal by an auditor. Lda. capital is freely fixed and divided into quotas, subject to a minimum of EUR1 per quota. An S.A. requires at least EUR50,000, represented by par value or no par value shares, never both, with a floor of EUR0.01 per share and 30% of cash contributions paid up at incorporation.

A capital increase requires a shareholders’ resolution specifying the type, amount, contributions, premium and deadlines. An authorised capital clause allows the board to increase capital without a fresh shareholder vote, subject to a ceiling, a term capped at five years and the rights of the shares issued. Reductions require creditor notice protections. Portuguese law has no concept of stated capital accounts – their protective function is performed by the single registered share capital figure, the distribution limits and the mandatory legal reserve.

The distinctions drawn are between subscribed, paid-in and unpaid-in capital, reserves including a mandatory legal reserve of 5% of profits up to 20% of capital, share premium and other equity items. The premium may not be deferred, and contributions in services are not admissible.

A joint stock company may issue preference shares, including non-voting shares, trading voting power for a priority dividend. The total nominal value of non-voting preference shares may not exceed one half of the share capital. Dividend, redemption and liquidation terms are set in the articles and typically require qualified majority and class consent.

The right to appoint a director may not be attached to a category of shares, although a veto may be, and special rights attach to a category and never to a named shareholder.

An Lda. has much less flexibility, since quotas are not shares, although bespoke quota rights remain negotiable.

Portuguese law governs distributions through a balance sheet test applied to formally approved accounts. A Portuguese company may not distribute assets to shareholders where its equity, including the result for the year, is lower than the sum of share capital and non-distributable reserves, or would become so as a result of the distribution. Profits needed to cover losses carried forward or to build mandatory reserves may not be distributed.

There is no separate cash flow or solvency test, and no directors’ solvency statement is required. Unless the articles or a shareholders’ resolution passed by the majority required to amend the articles provide otherwise, at least half of the distributable profits of each financial year must be distributed. Interim dividends are of limited practical use.

A return of capital requires a formal capital reduction, including a qualified shareholders’ resolution and registration with the Commercial Registry, with creditors generally entitled to object where the reduction is not made to cover losses, and capital may not fall below the statutory minimum.

An S.A. may repurchase its own shares up to 10% of capital, funded only from distributable reserves; such treasury shares carry no voting rights. Redeemable preference shares may be redeemed on terms set in the articles, funded from distributable profits or reserves or accompanied by a capital reduction; comparable rules apply to an Lda.’s own quotas.

Financial assistance is prohibited: a company and its subsidiaries may not provide loans, funds or security to enable a third party to acquire the company’s own shares, subject only to narrow exceptions for ordinary banking transactions and employee share acquisitions.

The principal control person disclosure regime for private companies in Portugal is the Central Register of Beneficial Owners (RCBE), which transposes the EU anti-money laundering framework. It applies to all Portuguese legal entities, including private companies, in contrast to the qualifying holding notification regime under the Portuguese Securities Code, which applies only to listed and public interest entities. A beneficial owner is any natural person who ultimately owns, controls or benefits from the company, assessed by reference to a holding of more than 25% of shares, voting rights or capital, although control may also arise through the power to appoint senior management or through contractual decision-making authority.

The statement must be filed within 30 days of the company’s incorporation, updated within 30 days of any change, and confirmed annually by December 31st. Non-compliance carries fines together with practical restrictions, including the inability to open a bank account, distribute profits, bid for public contracts or complete securities and real estate transactions until the position is regularised. The register is not freely accessible: a third party seeking access must demonstrate a specific and substantiated legitimate interest, typically tied to anti-money laundering compliance or to a transaction, and every consultation is logged.

On the tax side, companies must report related-party transactions annually and indicate whether transfer pricing documentation has been prepared. Entities whose total annual income reaches EUR10 million must maintain a master file and a local file, although transactions below EUR100,000 per counterparty and EUR500,000 in aggregate are exempt, and smaller enterprises may use a simplified file. Neither exemption applies to counterparties in a clearly more favourable tax regime, and neither displaces the arm’s length principle.

Corporate governance in Portugal is based mainly on the Portuguese Companies Code, which sets out the governing bodies, duties and liability for all commercial companies, supplemented for listed companies by the Portuguese Securities Code. It is overseen by the Portuguese Securities Market Commission (CMVM), and further complemented by the Legal Framework for Audit Supervision, the Statute of the Order of Statutory Auditors, and the CMVM regulation on the governance of listed companies.

The Companies Code governs the various types of company set out in Article 1 thereof, whereas the Securities Code imposes heightened transparency and governance obligations on issuers whose securities are admitted to trading in regulated markets. Corporate governance codes – in particular the Corporate Governance Code issued by the Portuguese Institute of Corporate Governance (Instituto Português de Corporate Governance) (the IPCG Code) – provide recommendations and best practice guidance that complement this statutory framework, on a “comply or explain” basis, rather than substituting for it. A listed company must adopt the IPCG Code or another recognised code and disclose its compliance annually in the corporate governance report. Unlisted companies are under no such obligation but are increasingly adopting such a code voluntarily.

The Shareholders’ Rights Directive and the Audit Directive have both been transposed, and the Bank of Portugal and the Insurance and Pension Funds Supervisory Authority (Autoridade de Supervisão de Seguros e Fundos de Pensões – ASF) impose heightened governance standards in the sectors they supervise.

Directors owe duties of care and loyalty, and duties to manage the company in its best interests, avoid conflicts of interest and refrain from appropriating business opportunities or competing without authorisation. Directors are liable to the company for breach of their legal, contractual and fiduciary duties. Fault is presumed, with the burden of proof resting on the director.

The Companies Code provides a business judgement rule protecting directors who act on an informed basis, free of personal interest and by rational business criteria, albeit not in cases of fraud, conflict of interest or a clear lack of diligence, which makes the documentation of decisions essential.

Liability is joint and several, subject to a right of recourse between directors by degree of fault. A company may claim damages to its own assets, and creditors may claim where a breach of protective rules leaves the company unable to satisfy its creditor claims. Shareholders or third parties may claim for direct harm. Common grounds include decapitalising the company, self-dealing, unlawful distributions and misleading financial information.

Directors of an S.A. must provide security against their potential liability, in the amount of EUR250,000 for a listed company and EUR50,000 for other companies, which the shareholders may waive. Directors’ and officers’ liability insurance is widely used and the company may bear the premium, except where the policy is intended to substitute for that statutory security. Indemnification by the company is not regulated in the Companies Code and is generally accepted, but an indemnity purporting to relieve a director of liability for breach of a fiduciary duty is void.

Because disputes of this kind are commonly referred to arbitration, as described in 4.1 Legal Framework, the documentary record of a decision rather than judicial authority determines whether the business judgement rule is available.

The criminal liability of a legal person is excluded where the perpetrator acted against the express instructions of a person in a leadership position, which is what gives the compliance programme described in 5.5 Internal Controls and Whistle-Blower Regimes its defensive value.

The regime varies by legal form and listing status. Private companies face no general independence or diversity requirements, while a joint stock company may adopt one of three governance models:

• a board with a supervisory board or sole auditor;
• a board with an audit committee and statutory auditor; or
• a two-tier structure with an executive board and a general and supervisory board.

An Lda. may be managed by one or more managers. In an S.A., board size is set in the articles, subject to a minimum of two directors, although a company with capital not exceeding EUR200,000 may appoint a sole director.

Directors are appointed for a term fixed in the articles, not exceeding four years, and may be re-elected. The general meeting may remove a director at any time without cause, with compensation being payable up to the remuneration due to the end of the term. A listed company must also appoint a company secretary.

Supervision is exercised as follows:

• by a sole auditor or a supervisory board of at least three members including a statutory auditor;
• under the audit committee model, by at least three non-executive directors; and
• under the two-tier model, by a general and supervisory board larger than the management body.

Listed and large companies must adopt a reinforced structure with an independent member of recognised expertise and a statutory auditor outside the supervisory board.

There is generally no residence requirement for directors.

Listed companies are also governed by CMVM regulations and by the IPCG Code on a comply-or-explain basis.

Independence is assessed substantively and is precluded by, among other things, a shareholding of 2% or more, re-election for more than two terms, or close family ties to a person subject to the same preclusion, and requires a documented individual assessment.

Diversity requires disclosed policies and justified deviations from them, with binding gender thresholds for listed companies and state-owned enterprises. The operative threshold is 33.3% of each gender in the governing bodies. Non-compliance results in a declaration of non-compliance by the regulator and renders the appointment provisional; the company has 90 days to remedy the position.

The IPCG Code recommends that independent directors make up at least one third of the non-executive members. There is no maximum number of terms; re-election beyond two terms bears on independence rather than eligibility. A legal person may be a director provided it designates a natural person to exercise the office, and directors need not be shareholders.

ESG obligations in Portugal are essentially of EU origin and are largely limited to large undertakings. All companies face a light, materiality-gated duty to include non-financial performance information in the management report, while large public interest entities with more than 500 employees must present a fuller non-financial statement (under the non-financial reporting regime), alongside the already-in-force EU Taxonomy Regulation.

Climate risk must already be factored into ordinary financial reporting where it could materially affect assets, results or going-concern status, and the Sustainable Finance Disclosure Regulation imposes parallel obligations on financial sector product disclosures.

There is no freestanding “ESG duty” for directors, but the Companies Code requires directors to consider stakeholders relevant to the company’s sustainability, such as employees, customers and creditors, alongside shareholders’ long-term interests. The Climate Framework Law, in force since 2022, goes further, requiring companies to take climate change into account in their governance and to build climate risk analysis into their decision-making.

Best practice, per the IPCG Corporate Governance Code, includes:

• clear board-level ownership of ESG oversight;
• integrating ESG into risk management;
• board oversight of sustainability reporting and assurance;
• linking remuneration to sustainability metrics;
• stakeholder engagement; and
• ensuring the board itself has adequate ESG competence.

The IPCG Code was revised in 2023 to add a dedicated chapter on sustainability.

Conflicts of interest and related-party transactions are governed by the Portuguese Companies Code, the Portuguese Securities Code, applicable CMVM rules, the Market Abuse Regulation (MAR) and the applicable accounting standards.

Directors and managers must act in the company’s interest, in compliance with their duties of care and loyalty. In a joint stock company, transactions between the company and a director are subject to the authorisation and conflict management safeguards of the Companies Code, which extend to transactions with entities in a control or group relationship with the director. Shareholders are barred from voting in the circumstances of conflict of interest expressly provided for by the Companies Code.

For issuers whose shares are admitted to trading on a regulated market, the Portuguese Securities Code requires an annual corporate governance report, as described in 5.2 Continuous Disclosure. Related-party transactions may also require disclosure under the MAR where the relevant information constitutes inside information.

Following the transposition of the Shareholders’ Rights Directive II, the Portuguese Securities Code establishes a specific regime for related-party transactions by listed issuers. The regime requires an internal procedure approved by the management body and a prior binding opinion from the supervisory body. Transactions outside the issuer’s ordinary course of business or not concluded on normal market terms may require management approval and public disclosure.

The shareholders’ basic rights are:

• to share in profits;
• to participate in resolutions;
• to obtain information; and
• to be eligible for the governing bodies.

Voting generally follows one-share-one-vote, and ordinary decisions are taken by simple majority. Fundamental changes, such as amendments to the articles, mergers, demergers and dissolution, require a qualified majority: two thirds of the votes cast in a joint stock company, and three quarters of the votes corresponding to the share capital in a private limited company.

In a joint stock company, an amendment to the articles may be resolved at first call only if at least one third of the share capital is present or represented, and at second call irrespective of the capital present. Shareholders may resolve in writing only where the resolution is adopted unanimously. Retroactive effects need unanimous consent, and no amendment can increase a shareholder’s obligations without their agreement.

Information rights scale with company type. An Lda. shareholder has broad access regardless of holding, while in a joint stock company 1% of capital is needed to consult accounts, minutes and remuneration data, preparatory documents are available 15 days before meetings, and clarification may be requested during the meeting. Shareholders holding 10% together may demand written answers outside the meeting, with unjustified refusal being challengeable by judicial inquiry. Notice convening a general meeting must be published at least one month in advance for a non-listed company and 21 days in advance for a listed company.

Shareholders holding 5% of the share capital, or 2% in a listed company, may require the board to call a general meeting and may propose agenda items. Resolutions may be challenged as void, or as voidable within 30 days, and shareholders meeting the same thresholds may bring a derivative action against directors where the company does not act.

Minority shareholders also have a direct route onto the board. The articles may reserve the appointment of up to one third of the directors to shareholders holding between 10% and 20% of the capital, or give a minority of 10% or more that voted against the successful proposal the right to appoint one director. A listed company must adopt one of the two schemes.

Shareholders’ agreements are commonly used to layer bespoke governance rights on the statutory framework: board appointment rights, veto powers and exit mechanics such as tag-along, options and pre-emption. Such an agreement takes effect only between the parties; acts of the company or of shareholders towards the company cannot be challenged on the basis of it. It may govern the exercise of voting rights but not the conduct of directors or supervisory board members, and a clause obliging a shareholder to vote as the company instructs, or to vote or abstain in return for special advantages, is void.

In a listed company, an agreement for the concerted exercise of voting rights causes those rights to be attributed to each party under the Securities Code, so that the aggregate may cross a qualifying holding threshold or trigger a mandatory bid. An agreement aimed at acquiring or reinforcing a qualifying holding, or at affecting the outcome of a bid, must be notified to the CMVM, which may order its disclosure.

Transfer restrictions differ by corporate form. The articles of a joint stock company may condition transfers on the company’s consent or on a pre-emption right, provided this serves a genuine company interest. Quota transfers must be in writing and generally require the company’s consent; further conditions may not be arbitrary, and an outright prohibition gives a right of withdrawal after a period fixed by law.

On disputes, Portugal has no direct equivalent to the unfair prejudice petition. The closest tool is the annulment of a resolution that is illegal, contrary to the articles or an abuse of majority voting power, which is available to any shareholder who did not vote in favour. A derivative action allows qualifying shareholders to pursue directors; a disruptive shareholder may be judicially excluded from a private limited company with a mandatory buyout; and deadlock may be resolved through judicial dissolution.

M&A are governed mainly by:

• the Companies Code for private deals;
• the Portuguese Securities Code and CMVM regulations for public transactions;
• the Competition Act for merger control; and
• the relevant EU rules.

Sectoral clearances may be needed from the Competition Authority (AdC), the Bank of Portugal, the ASF or the energy and communications regulators, and foreign direct investment screening applies to strategic sectors. The EU Foreign Subsidies Regulation adds a further clearance layer.

Portugal does not have a court-sanctioned scheme of arrangement. The closest analogue is the Processo Especial de Revitalização, a court-confirmed restructuring procedure under the Insolvency Code.

Private deals follow a standard path: confidentiality agreement, letter of intent, due diligence, promissory contract, share purchase agreement and closing. Statutory mergers are registry-based, requiring a merger project and shareholder resolutions, with registration triggering universal transmission of assets by operation of law.

Listed company acquisitions proceed by voluntary, mandatory or potestative bid: mandatory once voting rights reach one third or exceed one half, and potestative once an offeror controls 90% of the voting rights and of the share capital, all under CMVM supervision. Outside the capital markets, a holder of at least 90% of the share capital may offer to acquire the remaining shares, within six months of crossing that threshold, with the minority having a corresponding sell-out right.

A share purchase agreement remains the most common structure, with mergers, carve-outs and demergers also used, often alongside warranty and indemnity insurance.

Reported case law is a limited guide, since disputes are commonly referred to arbitration and awards are not published.

Employee involvement is procedural but drives timing. In a merger or demerger, the project must be registered and published, and employee representatives have at least 30 days in which to give an opinion. In an asset deal, the transfer of undertakings regime applies, as described in 10.1 Employment Standards and Workplace Regulation, but not to a pure share deal.

A seller has no general statutory disclosure duty. The courts read a duty of good faith into the Civil Code, so that circumstances material to the buyer’s decision should be disclosed and information given must be accurate. Breaking off negotiations without justification may give rise to liability for culpa in contrahendo, as described in 7.1 Contract Formation and Enforceability.

Portuguese capital markets regulation rests on the Portuguese Securities Code, read with EU law at two levels. The Prospectus Regulation, the MAR and MiFIR apply directly, as amended by the EU Listing Act; MiFID II, the Transparency Directive and the Takeover Bids Directive take effect through the Code.

The CMVM approves prospectuses and supervises market conduct, and Euronext Lisbon operates the only regulated market on which shares are admitted to trading. Where banks or insurers raise capital, the Bank of Portugal and the ASF are involved in their prudential capacity.

Offering Process and Approval

Public offers follow a disclosure path built around an announcement and a prospectus submitted to the CMVM for approval, with the scrutiny period being shorter where the issuer already has securities admitted to trading. Where new shares are issued for cash, existing shareholders have a statutory pre-emption right, which may be limited or disapplied only where the corporate interest justifies it, by a separate resolution passed by the majority required for the capital increase. That mechanic usually drives the timetable more than the prospectus does.

Listing and Continuing Obligations

Listing is a separate track, as Euronext Lisbon reviews eligibility on its own timetable. Admission requires a minimum free float of 10%, reduced from 25% by the transposition of the Listing Act; the market operator may accept less where orderly functioning of the market is assured.

Once admitted, companies face the continuing obligations described in 5.2 Continuous Disclosure. Euronext Lisbon also operates Euronext Access and Euronext Growth as multilateral trading facilities, admission to which does not of itself trigger the regulated market obligations.

Exemptions and Resale

Portugal no longer maintains a separate category of private placement, so the question is answered entirely by the EU exemptions. There is likewise no domestic accredited investor concept; the relevant category is the qualified investor, meaning a professional client or eligible counterparty under MiFID II, with other investors able to opt up.

The exemptions are the EU-wide ones:

• offers only to qualified investors;
• offers to fewer than 150 persons per member state;
• a minimum denomination of EUR100,000;
• employee share schemes;
• merger-related offers; and
• securities fungible with securities already admitted to trading representing less than 30% over a 12-month period.

A further exemption applies to offers below EUR12 million per issuer or offeror in the European Union over a rolling 12-month period. Member states may set that lower, at EUR5 million, and Portugal has not done so.

An exemption relieves the issuer of the prospectus requirement and of nothing else: market abuse, marketing communication and equal treatment rules continue to apply.

A resale is assessed as a fresh offer. Reliance on an existing prospectus requires the issuer’s written consent, which will not be available where the securities were placed under an exemption, so the resale needs its own prospectus or exemption. There is no statutory holding period, so any lock-up is contractual.

Breach of the offering rules is an administrative offence carrying significant fines and allowing the CMVM to suspend or prohibit the offer, with civil liability to investors.

Issuers admitted to trading on a regulated market are subject to the transparency duties set out in the Securities Code, MAR and CMVM regulations. Information disclosed must be complete, true, current, clear, objective and lawful, communicated to the CMVM in advance of publication and made available to investors promptly and without discrimination. Dissemination takes place through the CMVM information system, and mandatory information must remain available on the issuer’s website for a minimum period.

The annual report and accounts must be published within four months of the financial year end and kept available for ten years, accompanied by an annual corporate governance report. Half-yearly information must be disclosed within three months of the end of the first half-year.

Inside information – ie, precise, non-public information that is likely to have a significant effect on price – must be disclosed as soon as possible. Disclosure may be delayed only where the issuer has a legitimate interest, the delay is not likely to mislead the market and confidentiality is maintained, with the CMVM being notified once disclosure takes place. Issuers must keep insider lists, and dealings by directors, senior managers and their close associates above the applicable annual threshold must be notified and made public. Material related-party transactions are subject to similar disclosure duties.

Shareholders must also notify the CMVM and the issuer when their voting rights cross the thresholds set out in 5.4 Shareholder Disclosure.

Non-compliance is treated as an administrative offence enforceable by the CMVM.

Market abuse in Portugal is governed by MAR and the Portuguese Securities Code, with prohibitions following those of the Regulation:

• dealing on inside information;
• recommending or inducing another to deal on it;
• unlawful disclosure; and
• market manipulation by transaction, by order or by the spreading of information.

Issuers must disclose inside information promptly. Disclosure may be delayed only on the conditions set by MAR, and the CMVM must be given a written explanation of any delay. Issuers must also keep insider lists and tell the persons on them, in writing, what their obligations are. Firms that professionally arrange or execute transactions must report suspicious orders and transactions.

Two criminal offences apply, insider dealing and market manipulation, each punishable by imprisonment or a fine. A further offence covers the use of false or misleading information to obtain investment or financing, and carries a heavier sentence, with an aggravated form.

The CMVM supervises these matters and may demand information and inspect, investigate and restrict the marketing of financial instruments or the taking of positions. Legal persons are liable for administrative offences, with that liability being excluded only where the agent acted against specific written instructions given beforehand.

Conduct not prosecuted as a crime is sanctioned by the CMVM as an administrative offence. The highest fine bands attach to the use or transmission of inside information and to manipulation, and a fine may be increased by reference to the economic benefit obtained. The CMVM may also cancel registrations and revoke authorisations, and may reduce a fine where the person confesses or co-operates. Please see 5.5 Internal Controls and Whistle-Blower Regimes regarding whistle-blowing channels and the protection of whistle-blowers.

The disclosure of qualifying shareholdings is governed by the Portuguese Securities Code, which implements the EU Transparency Directive framework and is supervised by the CMVM. The regime applies to companies whose shares are admitted to trading on a regulated market. It captures voting rights held directly and those attributed through controlled companies, voting agreements or related-party arrangements, and certain financial instruments settled physically or in cash.

The duty to report arises whenever a person’s participation reaches, exceeds or falls below the thresholds of 5%, 10%, 15%, 20%, 25%, one third, 50%, two thirds or 90% of voting rights. The communication must be made as soon as possible, and no later than four trading days after the triggering event or after the holder becomes aware of it, and must be sent to the company concerned and to the CMVM at the same time. The obligation applies to individuals and legal entities alike, and to parent companies in respect of the voting rights held by their subsidiaries.

Where a communication is missing or ownership is unclear, the CMVM may first notify the interested parties and the company, and inform the market. If the situation remains unresolved, the CMVM may formally declare a lack of transparency, triggering the immediate and automatic suspension of the voting rights and patrimonial (equity) rights attached to the participation, with the exception of pre-emption rights on capital increases, until transparency is restored. Separately, a failure to comply with the disclosure duty can also expose the holder to the CMVM’s general administrative offence regime.

Entities (including public entities) with 50 or more employees are required to maintain an internal reporting channel, along with certain sector-specific entities (financial services, AML) regardless of size, and specified public bodies. The whistle-blowing channel’s required features are:

• secure submission;
• confidentiality or anonymity;
• independence; and
• freedom from conflicts of interest.

A parallel channel obligation exists under the General Regime for the Prevention of Corruption (RGPC) at the same 50-employee threshold, usually run as a single combined channel.

There is no single statute mandating internal control systems generally. The legal basis is the directors’ duty of care, reinforced for listed companies and the soft law IPCG Corporate Governance Code’s recommendations. The RGPC is the most prescriptive general instrument.

Sector-specific regimes add further requirements, such as the anti-money laundering legislation for obliged entities and Bank of Portugal regulations for credit institutions. The RGPC requires entities established in Portugal with 50 or more employees, including Portuguese branches of foreign companies, to adopt five instruments:

• a corruption and related offences prevention plan;
• a code of conduct;
• prior assessment procedures;
• a training programme; and
• an internal reporting channel.

Secured transactions are governed principally by the Civil Code, the Land Registry Code, the Insolvency and Corporate Recovery Code (CIRE) and the Code of Civil Procedure, supplemented by the financial collateral and commercial pledge regimes.

The recognised forms are:

• mortgages;
• pledges;
• financial collateral arrangements;
• assignments of receivables by way of security;
• retention of title; and
• personal guarantees.

Mortgages are used over registrable assets and pledges over movables, quotas, shares, receivables and bank accounts, and both may secure future obligations.

A mortgage must be registered; it is ineffective without registration, even between the parties. A possessory pledge requires delivery of the asset, or of a document conferring exclusive control, to the creditor or a third party. For pledges over rights, the formalities follow those for a transfer of the right, and for receivables effectiveness requires notice to or acceptance by the debtor, unless the pledge is registrable.

Priority follows the statutory regime and, for registrable security, the rank of registration, with a mortgage taking preference over creditors without a special privilege or earlier registration. Registration does not settle ranking on its own: preferential claims for tax and employment credits compete with registered security, and certain of them prevail over it even where the security was constituted first.

Enforcement is generally judicial, although an extrajudicial sale of pledged assets may be agreed.

Direct appropriation of the encumbered asset on default is prohibited under the general ban on the pacto comissório. The exceptions that matter are the financial collateral regime, which allows appropriation or sale outside court and survives a declaration of insolvency, and the commercial pledge regime. The financing documentation should also provide a suitable enforcement title, since a mortgage deed that merely creates security may not suffice.

In acquisition financings, the senior facility is advanced to a Portuguese acquisition vehicle, secured by a pledge over the target’s shares or quotas and over the vehicle’s accounts and receivables. Security over target assets is considered after closing and remains subject to corporate benefit and to the financial assistance restrictions.

There is no statutory intercreditor regime. Ranking is addressed by contractual subordination, standstills and a security agent structure, all operating inter partes only. Security granted shortly before insolvency may be exposed to resolution for the benefit of the estate.

Shareholder and vendor loans are frequently subordinated by contract, and claims of persons specially related to the debtor are subordinated by operation of law. Prestações suplementares are equity-like contributions available only in a private limited company and are not equivalent to shareholder debt.

Stamp duty on credit is a first-order structuring consideration. Shareholder advances are exempt where the term is not less than one year and the lender holds at least 10% of the capital, with early repayment causing the exemption to fall away, whereas group treasury arrangements are exempt only where the term does not exceed one year.

The general framework for commercial contracts comprises the Civil Code, the Commercial Code and the General Contractual Clauses Regime.

The parties are free to fix the content of their contract, within the limits of the law, departing from or combining the statutory contract types, subject throughout to good faith. A contract is formed by a serious offer and a matching acceptance; there is no doctrine of consideration, and no form is required unless the law prescribes one, as for real estate and certain intellectual property transfers.

The parties must have capacity, which for companies means verifying the signatory’s powers of representation and the corporate approvals required, and the object must be lawful, possible and at least definable. Interpretation proceeds from the meaning that could be deduced from the declaration by a normal addressee, placed in the position of the actual addressee.

A serious defect makes the contract null, as with an unlawful or impossible object, breach of a mandatory rule or a missing formality. Nullity may be raised at any time by any interested party, and declared by the court of its own motion. Annullability, the lesser category, applies to error, fraud, duress and usury. The contract produces its effects until annulled and only the protected party may invoke it, within one year of the cessation of the defect.

The general contract terms regime applies between businesses and also to consumers wherever terms are not individually negotiated. The party imposing them must communicate and explain them, and bears the burden of proof.

Good faith is required in the formation of a contract, and a party that breaks off negotiations without justification may be liable for culpa in contrahendo, with recovery being limited to the negative contractual interest.

A court may reduce a manifestly excessive penalty, and that power cannot be excluded by agreement. Where a penalty is stipulated, the innocent party may not claim damages beyond it unless the contract expressly preserves that right, so a penalty intended as a floor operates as a cap unless drafted otherwise.

Liability for wilful misconduct or gross negligence cannot be validly excluded in advance. Case law generally accepts carefully drafted limitation clauses for ordinary negligence in business-to-business contracts, and a cap may be enforceable even where a complete exclusion would not. Consumer standard terms are stricter, as described in 7.4 Consumer Protection.

The ordinary limitation period runs to 20 years, but interest and other periodic obligations prescribe in five years and non-contractual liability in three.

Portuguese law does not treat force majeure, frustration of purpose or hardship as autonomous doctrines in the common law sense. Their closest counterparts in the Civil Code are supervening impossibility, loss of interest in performance following delay, and abnormal change of circumstances.

A debtor who culpably fails to perform is liable for the creditor’s loss, with fault being presumed subject to proof that the breach was not attributable to said loss. The creditor may seek performance, damages for loss suffered and lost profits, and may rely on agreed remedies such as a penalty clause.

Where breach consists only of delay, termination is not immediately available. The creditor must serve an admonitory notice fixing a reasonable final period for performance and stating that failure to perform within said period will be treated as definitive non-performance. Termination is available without such notice where the creditor has objectively lost its interest in performance.

Termination is a unilateral potestative remedy requiring a statutory or contractual basis:

• impossibility through the debtor’s fault;
• delay converted into definitive non-performance;
• an objectively justified loss of interest; or
• a valid express termination clause.

It is effected by notice.

A purported termination without a valid basis is ineffective. The terminating party is itself in breach, and the counterparty may elect between specific performance and termination, in either case with damages.

The effects of a valid termination are assimilated to those of nullity, normally with retroactive effect, save that in continuing contracts performance already rendered is unaffected.

Force majeure is addressed through supervening impossibility. If performance becomes objectively impossible due to a cause not attributable to the debtor, the obligation is extinguished, and the other party is released from its counter-performance and may recover what it has provided. Contractual force majeure clauses remain important to define covered events, notification duties and risk allocation.

Hardship is addressed by the rule on abnormal change of circumstances. A party may seek termination or equitable adjustment where:

• the circumstances on which the decision to contract was based have changed abnormally;
• performance would seriously offend good faith; and
• the change falls outside the contractual risk assumed.

A party already in delay cannot rely on the provision. The courts apply the remedy restrictively: economic difficulty or a general reference to an event such as the COVID-19 pandemic will not suffice without proof of an abnormal and serious disturbance of the contractual equilibrium.

IP transaction documents should distinguish between an assignment and a licence, and define the rights concerned, the territory, the duration and the remuneration. Quality control is a matter of commercial choice rather than of validity.

For industrial property, a transfer inter vivos need only be proved by written document, but transfers, licences and security interests are subject to registration before the INPI and produce erga omnes effects only from the date of recordal.

For copyright the requirement is stricter. A total and definitive transfer of the economic content of copyright can be effected only by public deed identifying the work and stating the price, failing which it is void. A partial transfer requires a written document with notarised signatures; where no duration is stated, it is presumed to be 25 years, or ten for photographs and works of applied art.

Copyright belongs initially to the intellectual creator. In commissioned works, ownership follows the parties’ agreement and, failing agreement, is presumed to remain with the creator, except where the creator’s name does not appear in the work.

Authorisation to use a work is distinct from an assignment and transfers no copyright, even where exclusive. It must be granted in writing, is presumed to be non-exclusive, and is valid only for the specified form of exploitation.

Software is governed by its own regime and the default runs the other way: rights in a program created by an employee in the exercise of their functions belong to the employer unless otherwise agreed.

Patents follow a third pattern. The right belongs to the inventor, but where the invention is made under an employment contract providing for inventive activity it belongs to the employer. Consultants retain ownership unless otherwise agreed.

Trade secrets are protected for as long as the information remains secret, has commercial value because it is secret and has been the subject of reasonable steps to keep it so. Protection therefore depends on the holder’s own conduct.

Unregistered marks are not protected as such but may be enforced through unfair competition, and a company name may be asserted against a later mark on proof of likelihood of confusion.

The holder of an infringed right may seek interim measures and, at trial, damages, together with recall and destruction of infringing goods, before the Intellectual Property Court.

Where the loss cannot be quantified, the court may fix an equitable sum, with a floor set by the royalty the infringer would have paid had it sought authorisation. Compensation may be claimed only for acts within three years of the injured party becoming aware of the harm.

For AI-generated content, copyright is anchored in the human intellectual creator, so contracts should regulate the human contribution and the tool’s terms.

Consumer protection is anchored in the Consumer Protection Law, reinforced by the regimes on:

• distance and off-premises contracts;
• unfair commercial practices;
• general contractual terms;
• advertising;
• electronic commerce; and
• conformity of goods and digital content.

Before contracting, the supplier must give clear information on the essential characteristics of the goods or services, the total price, any ancillary charges and the legal guarantees. Where that information is not intelligible, the consumer acquires a withdrawal right of seven business days.

Two cooling-off periods therefore operate side by side. The seven-day right arises from defective information; in distance and off-premises contracts, a separate right of withdrawal runs for 14 days and needs no reason. A term imposing a charge for withdrawal is invalid, and withdrawal takes effect on an unequivocal communication rather than on return of the goods.

Advertising statements that are concrete and objective become part of the contract and prevail over inconsistent terms. Express consent is required for any additional payment, so pre-ticked boxes that generate charges entitle the consumer to restitution.

Standard terms face a fairness review: they must be clear and compatible with good faith, and may not create a significant imbalance against the consumer. Any provision excluding rights conferred by the Consumer Protection Law is void.

Regulators bring administrative offence proceedings and impose fines. For the most serious offences, the fine reaches EUR90,000, rising to 4% of annual turnover in the member states concerned where the infringement is widespread and pursued through co-ordinated action at EU level.

The Economic and Food Safety Authority (Autoridade de Segurança Alimentar e Económica, or ASAE) is the principal authority, with sectoral supervision falling to the Directorate-General for Consumer Affairs.

Consumers may seek performance, invalidity, withdrawal, restitution, price reduction, repair or damages. Injunction actions lie to stop prohibited standard terms and unlawful practices, and are exempt from court fees; a final condemnatory judgment is published at the infringer’s expense.

Alongside these sit mediation, the consumer arbitration centres and the complaints book. In low-value disputes, the consumer may refer the matter to an arbitration centre and the trader is obliged to take part, so participation is not a matter of consent.

Collective redress is available through popular actions and through claims brought by designated entities.

The test for misleading and aggressive practices is whether the practice, including an omission of material information, is liable to cause the average consumer to take a transactional decision that would not otherwise have been taken.

For online contracts, traders must disclose the stages of contract formation and how input errors may be corrected, and must acknowledge electronic orders.

Recent reforms transposing the EU Omnibus Directive have tightened the rules on announced price reductions, on online marketplaces and on dual quality of goods.

Merger control is governed principally by the Competition Act and by the Portuguese Competition Authority (AdC) regulation setting out the notification forms. Prior notification is mandatory where any of the following thresholds is met:

• a market share of 50% or more in Portugal or in a substantial part of it;
• a market share of 30% or more but below 50%, provided at least two undertakings each generated Portuguese turnover exceeding EUR5 million in the preceding financial year; or
• aggregate Portuguese turnover exceeding EUR100 million in the preceding financial year, provided at least two undertakings each exceeded EUR5 million.

Notification must be made after conclusion of the agreement and before implementation, with no fixed deadline following signing. Early voluntary notification is possible where the parties show a serious intention to conclude the transaction.

The AdC’s review is conducted in two stages.

• Phase I: 30 working days from the date on which the notification becomes effective.
• Phase II: up to 90 working days from that same effective notification date, rather than an additional 90 working days after Phase I, extendable by up to 20 working days at the notifying party’s request.

The deadlines are suspended where the AdC requests information or the parties submit commitments, and failure to decide within the applicable deadline is deemed a non-opposition decision.

The substantive test is whether the transaction is liable to create significant impediments to effective competition in Portugal or in a substantial part of it, particularly through the creation or strengthening of a dominant position. The AdC considers market structure, the parties’ positions, barriers to entry and efficiencies benefiting consumers.

Implementation before notification and clearance is gun-jumping, which is an administrative offence giving rise to fines; legal acts carried out in breach of the standstill obligation are ineffective. Where a transaction has been implemented and is subsequently prohibited, the AdC may impose restorative measures, including reversal of the transaction.

The Competition Act also prohibits anti-competitive agreements, abuse of dominance and abuse of economic dependence as administrative offences carrying substantial fines, and a prohibited agreement is null and void unless the conditions for exemption are met.

Where a transaction has an EU dimension, the European Commission generally has exclusive competence, subject to the referral mechanisms.

Foreign investment is generally treated on the same basis as domestic investment. The principal exception is the National Strategic Assets Regime, which applies where a person from outside the EU or EEA acquires control over strategic assets. Control means decisive influence, and an investor counts as coming from outside the EU or EEA where its domicile, registered office or effective place of management lies outside those territories.

The assets are the main infrastructure connected with national defence and security, or with essential services in energy, transport and communications. There is no financial threshold: the trigger is the acquisition of control, and whether an asset is strategic is assessed on a case-by-case basis.

Portugal has no dedicated foreign investment authority. The government member responsible for the sector opens the assessment and the Council of Ministers decides. Opposition is available where the transaction gives rise to a real and sufficiently serious threat to national defence or security, or to the security of supply of essential services.

Seriousness is assessed against the security of the assets, their availability, the continuity of the services provided and the confidentiality of data. A threat is presumed where the acquirer has established links with third countries that do not observe the fundamental principles of the democratic rule of law, and any decision to oppose must be proportionate.

The regime is not a general pre-closing filing system, and two routes are open. An investor may seek confirmation of non-opposition, before or after completion; if no review is opened within 30 working days of the request, non-opposition is deemed. Otherwise, the transaction may be completed and left to review on the government’s own motion, opened within 30 working days of completion or of the transaction becoming public knowledge, whichever falls later. Once an assessment is opened, the acquirer has ten working days to submit information and the Council of Ministers has 60 working days from receipt of complete information in which to decide, with silence again operating as non-opposition, so that the procedure runs to roughly 90 working days. Where the Council of Ministers opposes, the relevant acts may be rendered null and void, and because no pre-closing filing is mandatory nothing else sanctions completion without clearance. The regime has been in force since 2014 but has been little used, with no opposition decision having been publicly reported.

Sector-specific approvals may apply. Acquisitions of qualifying holdings in credit institutions require prior notification to the Banco de Portugal where the holding reaches 10%, 20%, one third or 50% of the capital or voting rights. The Banco de Portugal examines suitability, financial soundness and money laundering risk, and may oppose the acquisition or restrict voting rights.

Foreign and domestic investors have access to the same incentives, including the contractual tax incentives for productive investment in the Investment Tax Code.

The principal recent development is the new EU screening regulation, taking effect from 17 January 2028. What matters is its mandatory common minimum scope, under which investments falling within it will need authorisation before closing. Portugal will therefore have to broaden the sectoral reach of its regime and introduce a standstill obligation.

Portugal’s data protection framework is built on the GDPR and the national implementing law, with the National Data Protection Commission (CNPD) as supervisory authority. The GDPR provides for administrative fines of up to EUR20 million or 4% of worldwide annual turnover, whichever is higher, for the most serious infringements.

Sector-specific layers apply to:

• employment, with strict limits on consent, biometrics and video surveillance used for discipline;
• healthcare, with heightened special-category protections including mandatory impact assessments where processing is likely to result in a high risk; and
• electronic communications, with opt-in marketing and cookie consent.

The GDPR requirements as to legal basis, transparency and data subject rights apply without national variation. Compliance in practice means records of processing, retention policies, impact assessments, incident management and a Data Protection Officer where required. Breaches must be assessed and documented, with CNPD notification within 72 hours where there is a risk to individuals, and direct notification to data subjects where the risk is high.

Cross-border transfers outside the EEA follow the standard GDPR mechanisms. There is no general data localisation requirement in Portugal, but remote access from a third country can itself count as a transfer even without data moving, so businesses should map their processing and vendors, and verify system locations.

Workplace monitoring is the issue that arises most often in a corporate context. Portuguese case law affords reinforced protection to employees’ personal or non-professional messages, including where stored on corporate systems. Access to the content of such communications may be unlawful, and evidence so obtained may be unusable, particularly where there are no clear, prior rules governing the use of corporate email. Personal data collected for anti-money laundering or anti-corruption purposes remains subject to purpose limitation and to the applicable legal basis for any further processing.

The AML/CFT regime is principally set out in the anti-money laundering and counter-terrorist financing statute. It follows a risk-based approach and applies to a broad range of obliged entities, including credit institutions, payment institutions, investment firms, fund managers and crypto-asset service providers, as well as casinos, real estate businesses, auditors, lawyers, notaries and other designated businesses.

Obliged entities must implement proportionate policies to assess and mitigate risk, identify customers and beneficial owners, and apply enhanced measures in higher-risk cases, including politically exposed persons. They must report immediately to the Central Department of Criminal Investigation and Prosecution (DCIAP) and the Financial Intelligence Unit whenever they suspect that funds derive from criminal activity or terrorist financing.

Portugal does not operate a separate national sanctions list. UN and EU restrictive measures apply directly, and obliged entities must maintain the systems necessary for their immediate implementation.

Money laundering is punishable by imprisonment of up to 12 years under the Penal Code, and terrorist financing by up to 15 years.

The supervisory authorities include the Bank of Portugal, the CMVM, the ASF and the ASAE, which may inspect, bring administrative offence proceedings and impose sanctions. On the anti-corruption side, the dedicated body is the National Anti-Corruption Mechanism.

The Penal Code criminalises active corruption, where an undue advantage is offered or promised, and passive corruption, where one is solicited or accepted, with the passive form being the more serious. A separate statute applies the same structure to holders of political office, and another criminalises corruption in the private sector, which is the limb that most concerns commercial organisations. A further offence covers active corruption in international trade, irrespective of where the conduct occurred. A company may be criminally liable where the offence was committed by persons in leadership positions acting on its behalf and in its interest, and is punished by fine, with ancillary penalties including exclusion from public procurement.

The general regime for the prevention of corruption applies to legal persons established in Portugal, and to Portuguese branches of foreign legal persons, employing 50 or more workers. Those entities must adopt a compliance programme containing, as a minimum, a corruption risk prevention plan, a code of conduct, a training programme and an internal reporting channel, and must designate a person responsible for compliance. Failure to do so is itself sanctioned.

Bribes are non-deductible for tax purposes, and facilitation payments are treated as bribery whatever their size. Corporate hospitality is not regulated as such, but only offers made in accordance with local custom fall outside the improper advantage offence. Political parties may not accept corporate or anonymous donations.

Portugal operates no plea bargaining and no deferred prosecution agreements, but a decisive contribution to establishing the facts at the investigation stage may facilitate mitigation or exemption from punishment, the latter also where the offence is reported before proceedings begin and the advantage is returned.

Environmental due diligence centres on the validity of environmental titles, on historical contamination liability and on whether an environmental impact assessment was required before licensing, with permits being consolidated into a Single Environmental Permit. There is no dedicated contaminated land statute, so liability for historical contamination falls on the polluter under the environmental liability regime, which makes buyer-side technical assessments standard practice on any site with an industrial history. Carbon exposure runs on two tracks: EU Emissions Trading System (ETS) reporting and allowances for covered installations, and a national carbon tax for activities outside the ETS, indexed to the prevailing ETS price.

Civil liability for pollution damage sits alongside that public remediation duty and is distinct from it. The Framework Law on the Environment enshrines the polluter-pays principle and preserves an injured party’s right to compensation alongside any administrative sanction, including the right to demand cessation of the polluting activity and restitution of the prior situation. In the absence of a bespoke pollution liability statute, such claims fall back on the general tort regime of the Civil Code, with fault-based liability as the default and strict liability for operations that are dangerous by their nature or by the means employed, which is the basis most often invoked against polluting industry. A single event may therefore give rise both to an administrative remediation obligation towards the State and to a separate civil claim.

Occupational health and safety is set at national level, with the Azores and Madeira operating their own regional labour inspectorates. Employers must prevent occupational risks, operate an occupational health and safety service, assess risks, inform and train workers, and carry compulsory work accident insurance. The Authority for Working Conditions (ACT) enforces the framework.

General licensing runs through the Balcão do Empreendedor, with industrial activity under the risk-tiered Responsible Industry regime (SIR). Sector rules then drive deal timing:

• energy requires production and grid titles from the Directorate-General for Energy and Geology (DGEG);
• financial services requires prudential authorisation with qualifying holdings and AML checks; and
• pharmaceuticals and medical cannabis require authorisation from INFARMED, with good manufacturing and distribution practice compliance. Recreational cannabis remains decriminalised for personal use but is not licensed commercially.

Portugal has no dedicated AI law and relies on the EU AI Act, supported by the National Artificial Intelligence Agenda and by the existing laws on data protection, cybersecurity, consumer protection and labour. ANACOM was designated as the national supervisory authority and single point of contact in September 2025, co-ordinating the sectoral regulators, with the CNPD retaining its role regarding personal data.

No national AI statute is planned, with the Regulation applying directly, and Portugal is separately required to establish at least one AI regulatory sandbox.

Obligations depend on an organisation’s role under the AI Act, whether as provider, deployer, importer or distributor. Bans on manipulative AI and baseline literacy requirements have applied since early 2025, and obligations for general-purpose AI models since August 2025. Transparency and deepfake-labelling rules took effect in August 2026, and high-risk system obligations, deferred by the Digital Omnibus on AI, now apply from December 2027 and August 2028. Portugal’s corporate governance code also expects boards to be transparent about their use of AI.

Portugal also has a domestic transparency duty that pre-dates the AI Act and is easily missed. The Labour Code requires an employer to disclose in writing the parameters, criteria and rules underlying any algorithm or AI system that affects access to or maintenance of employment, employment conditions, the construction of profiles or the monitoring of professional activity, and equivalent disclosure is owed to works councils and union representatives. Any deployment of AI in recruitment or performance management therefore engages employment law as well as the AI Act, and the data protection rules on automated decision-making where there is no human intervention.

The Regulation does not harmonise civil liability, but compliance with its requirements on risk management, documentation, logging and human oversight will bear on how fault and defectiveness are assessed under Portuguese law. The revised EU product liability regime, which Portugal must transpose by 9 December 2026, extends the notion of a product to software and AI systems, and introduces rebuttable presumptions of defectiveness and of causation where a case involves excessive technical complexity.

Cybersecurity is now a significant compliance requirement under NIS2 (Directive (EU) 2022/2555), transposed by Decree-Law No 125/2025, of 4 December, and in force since 3 April 2026, which requires substantive risk management, incident response planning, and mandatory notification to authorities when incidents occur, with financial entities being subject to an even stricter regime under the Digital Operational Resilience Act (DORA).

Portuguese employment law centres on the Labour Code, supplemented by collective bargaining agreements and by the adjacent regimes on social security, health and safety, non-discrimination and data protection. Job security is strongly protected, with indefinite-term contracts being the default, and dismissal requires just cause or a defined legal process rather than mere notice by the employer.

Termination follows several distinct routes, each with its own requirements:

• disciplinary dismissal for just cause (no notice or compensation required);
• collective dismissal or position elimination;
• dismissal for unsuitability (these “objective grounds” dismissals require written notice, consultation and advance notice, and compensation calculated in layers with variable seniority allowance per year); and
• fixed-term contract expiry and mutual agreement.

Notice periods for objective grounds terminations scale from 15 to 75 days by tenure. A dismissal is unlawful if it is unjustified, procedurally defective or discriminatory, or if it breaches special protections such as those applying during pregnancy, entitling the employee to reinstatement or compensation. Portugal’s equivalent of constructive dismissal lets an employee resign immediately for the employer’s serious breach, with similar compensation if the claim is upheld. Compensation for unlawful dismissal is a separate measure and the employee may elect reinstatement instead.

In a joint stock company, directors’ remuneration is fixed by the general meeting or by a remuneration committee appointed by it, having regard to the functions performed and to the company’s financial position, and may include a share of annual profits if the articles authorise a maximum percentage.

In a private limited company, managers are entitled to remuneration fixed by the shareholders, unless the articles provide otherwise, and such remuneration may not consist of a profit share unless the articles expressly permit it.

Equity incentive arrangements are not governed by any standalone employment law regime, so the documentation has to do the work, covering corporate approvals, vesting, leaver treatment, dilution and change-of-control acceleration. Cash and in-kind benefits may themselves count as remuneration where they are regular or contractually guaranteed.

A change of control does not in itself terminate employment contracts, so severance, acceleration and retention provisions must operate as express contractual entitlements. Directors may be removed at any time, and where removal is without just cause compensation may be due, subject to the statutory cap of the remuneration expected until the end of the term of office.

Cash remuneration and benefits are taxable as employment income, as are gains under equity plans to the extent that they are remuneratory, even where realised after the relationship has ended. Later gains on disposal fall within the capital gains regime, and the chargeable event may fall at grant, at vesting or at exercise.

During employment, employees owe duties of good faith and loyalty, which include not competing with the employer and not disclosing information about its organisation, production methods or business.

A post-contractual non-compete covenant is void if it restricts freedom to work after termination, and is enforceable only where it:

• is in writing;
• protects against an activity capable of causing harm to the employer;
• provides compensation throughout the restricted period; and
• does not exceed two years, extended to three for roles carrying a special relationship of trust or access to particularly sensitive competitive information.

The compensation may be equitably reduced where the employer has borne significant training costs.

There is no distinct statutory regime for non-solicitation covenants, so validity turns on substance and effect: a clause that in practice stops the employee working for a competitor will be measured against the requirements applying to non-competes.

Confidentiality obligations are more readily enforceable, provided they protect identifiable confidential information and do not operate as a disguised restriction on the freedom to work, and no further compensation is payable for maintaining confidentiality.

Portuguese property law recognises full ownership, co-ownership, horizontal property (condominiums), usufruct, surface rights, easements, leasehold as a personal rather than real right, and communal lands (baldios), with land classified as public or private domain.

Foreigners can buy, own and sell real estate on the same terms as Portuguese nationals, with no residency or licensing requirement. Buyers must be registered with the Portuguese Tax Authorities and must satisfy AML, beneficial ownership and source-of-funds checks. Acquisitions must be registered with the Land Registry.

Key taxes to factor in are:

• IMT (transfer tax);
• Stamp Duty (on both purchase and financing);
• annual IMI;
• AIMI for high-value holdings;
• tax on rental income; and
• capital gains.

A flat IMT rate of 7.5% applies to non-tax-residents acquiring urban property for residential purposes, disapplying the general progressive rates and the usual reliefs. The difference may be reclaimed where the buyer becomes tax-resident within two years or lets the property at capped rents.

Corporate buyers domiciled in blacklisted jurisdictions, and entities they control, are liable to IMT at a flat rate of 10% on any property, with no reliefs.

The commercial real estate framework rests on the Civil Code and the Land Registry Code, supplemented by the regime governing urbanisation and construction and by the urban lease regime. Ownership, mortgages and encumbrances are recorded at the Land Registry, where priority follows the order of registration, and a separate property tax register must be reconciled against it.

Deals can be structured as asset or share purchases, with due diligence covering:

• title and encumbrances;
• planning and use permits;
• consistency of the tax record;
• leases;
• condominium issues;
• environmental risk;
• litigation; and
• public law restrictions.

A mortgage must be registered in order to take effect, including as between the parties themselves, and mortgages rank by date of registration. Financing frequently layers security over shares, receivables and accounts alongside the mortgage. Enforcement is judicial, through sale of the asset by electronic auction, subject to the exceptions described in 6.1 Transaction Financing and Security Interests.

Commercial leases give landlords and tenants broad contractual freedom over term, rent, renewal and assignment, with a default five-year renewing term in the absence of agreement. Assignment and subletting generally require the landlord’s consent, except under the trespasse mechanism, by which a lease transfers automatically alongside the sale of a business, subject to the landlord’s right of preference and to a duty to notify.

The most significant recent change is the Simplex Urbanístico reform, which simplifies some licensing steps while tightening others. The 2024 framework remains operative.
