The dispute resolution team has substantial experience in court proceedings before various Thai courts, including the specialist courts, and also routinely represents debtors in business reorganisations and creditors in debt enforcement matters. The firm has advised on a broad range of real estate disputes, including disputes with contractors and land-related matters. The real estate practice advises on diverse aspects of property investment, such as the development of new projects; the acquisition, disposal and financing of existing properties; structuring for development projects; due diligence; and drafting and negotiating transactional agreements and documents, including matters related to real estate litigation.

Under Thai law, the landlord is responsible for keeping the leased property in a condition suitable for its intended use. The landlord must carry out all repairs that are necessary – except for minor repairs, which the law or common practice expects the tenant to handle.

Accordingly, even if the lease does not expressly grant access rights, Thai law gives the landlord statutory rights to enter the rented property and carry out the necessary work. If the tenant refuses to provide access, the landlord may file a court complaint to:

  • request court-ordered access (injunction) where repairs are necessary to preserve the property; or
  • claim damages if the refusal causes additional loss or deterioration.

Regulatory authorities do not generally intervene in private lease disputes. However, where access is required for safety-related repairs, particularly in high buildings (23 metres or more) or extra-large buildings (over 10,000 sq m), local authorities have statutory powers under the Building Control Act to order landlords (as landowners) to rectify unsafe systems (eg, fire safety, electrical, ventilation). If compliance requires access to leased units, such orders may effectively override a tenant’s refusal, as the obligation arises by law rather than contract.

Where urgent repairs are required during the lease term, the tenant must allow the landlord to carry out the necessary work. This obligation applies even if the repairs cause inconvenience to the tenant.

In addition to a landlord’s statutory right to carry out urgent repairs, Supreme Court precedents indicate that entry without consent in situations of necessity is not necessarily considered trespassing, provided that the entry is proportionate and limited to addressing the emergency.

A tenant’s refusal to provide access that interferes with neighbouring units may result in:

  • tort liability for wrongful acts causing damage or nuisance; or
  • claims from affected neighbours for compensation.

The landlord may rely on such impacts to justify seeking urgent legal relief by filing a court complaint against the tenant (see 1.1.1 Remedies for Landlords Denied Access for Repairs).

Although Thai law grants a landlord statutory rights to enter rented property for inspection, such inspection must be notified in advance and carried out at a reasonable time and for a reasonable duration.

In the case of repairs, if the work takes an unreasonably long time and renders the property unsuitable for its intended use, the tenant has the right to terminate the lease.

If a landlord engages in conduct that frustrates or impedes the tenancy, the tenant may:

  • claim for breach of contract and/or terminate the lease; or
  • file a tort claim for an unlawful act.

Thai law does not distinguish remedies based on rent control or stabilisation.

The consequences depend on whether or not the landlord falls within the consumer protection regime.

For regulated residential leasing businesses under the Consumer Protection Act (generally leasing five units or more), the Consumer Protection Committee may investigate and order the landlord to cease unfair or abusive practices, and may take enforcement action in the public interest. Unfair lease provisions may be rendered void, with exposure to administrative penalties and potential criminal liability for non-compliance.

For landlords outside this regime, there is no equivalent regulator; remedies are pursued primarily through the civil courts, as described in 1.2.1 Landlord Harassment.

Thailand does not have statutory tenancies, such as rent-controlled or rent-stabilised units. All leases in Thailand are effectively free-market tenancies from inception, with rent levels, lease terms and renewals generally governed by contract. Certain residential leasing businesses are subject to consumer protection rules (as noted in 1.2.3 Consequences of a Regulatory Finding of Landlord Harassment), which regulate contract fairness and landlord conduct, but do not regulate rent levels nor create statutory renewal rights.

As noted in 1.3.1 Statutory Tenancies: Types and Differences, Thailand does not have statutory tenancies.

As noted in 1.3.1 Statutory Tenancies: Types and Differences, Thailand does not have statutory tenancies.

As noted in 1.3.1 Statutory Tenancies: Types and Differences, Thailand does not have statutory tenancies.

Courts assess whether cure periods are reasonable in light of:

  • the nature of the breach; and
  • the practical time required to remedy it.

If a landlord fails to provide a reasonable cure period, the landlord bears the risk that the termination of the lease (if any) may be found invalid, and the landlord’s actions may be treated as a breach of contract. In this context, provisional relief typically takes the form of a temporary injunction restraining the landlord from terminating the lease or evicting the tenant from the leased property. To obtain such an injunction, the tenant must file a complaint with the court, together with an application for protective measures, and demonstrate that the claim has good cause and sufficient grounds to justify the court’s intervention.

If they fail to obtain an injunction within the cure period, the tenant may still continue with court proceedings and seek compensation for losses arising from the landlord’s breach of contract or unlawful termination.

Under Thai law, the exercise of a right in bad faith may constitute a tort. If the landlord repeatedly serves default notices or notices to cure in bad faith, the tenant may bring a tort claim for an unlawful act.

In Thailand, guarantees in tenancy arrangements commonly take the form of security deposits or bank guarantees. In residential tenancies, landlords typically rely on security deposits. In commercial tenancies, security deposits also remain the primary form of guarantee, and the parties may negotiate to include a bank guarantee as part of the overall security package; however, cash is generally required to constitute the main portion.

For regulated residential leasing businesses, security deposits are capped at no more than three months’ rent under the applicable consumer protection rules.

The ability to revoke a guarantee in Thailand depends on the type of guarantee provided. In general, guarantees are not revocable once provided. Security deposits are not revocable, as they constitute cash security already paid and are refundable only upon lawful termination of the tenancy. Bank guarantees are generally irrevocable once issued, except in accordance with their express terms.

Thailand does not provide a special expedited enforcement regime for guarantees. The speed and effectiveness of enforcement depend on the type of security.

Security deposits generally provide the most expedited form of recovery. A landlord may apply the security deposit against outstanding obligations that have become due at any time during the lease term or upon termination of the tenancy. Once the security deposit is applied, the tenant is typically required to top up any shortfall within the period specified in the relevant contract.

Bank guarantees may typically be called on demand in accordance with their terms. However, if the parties dispute the existence or amount of the outstanding obligations, the issuing bank may refuse to make payment to the landlord, which may result in court proceedings.

Foreclosure of mortgaged property is conducted through court proceedings.

Before enforcing a mortgage, the mortgagee must send a written notice to the debtor demanding payment of the debt. The notice must give the debtor a reasonable period to pay, which must be at least 60 days from the date the debtor receives the notice. If the mortgagor is not the debtor, the mortgagee must also notify the mortgagor in writing within 15 days from the date the notice is sent to the debtor.

If the debtor fails to pay within that period, the mortgagee may file a court case seeking seizure of the mortgaged property and sale of the property by public auction. Once a favourable judgment is obtained, the sale of the property is carried out by the legal execution officer, who is a state official responsible for executing court judgments.

Instead of selling the property by auction, transfer of ownership of the mortgaged property to the mortgagee is available only if both of the following conditions are met:

  • the debtor has failed to pay interest for at least five years; and
  • the mortgagee satisfies the court that the value of the property is lower than the outstanding debt.

Non-judicial foreclosure mechanisms are not commonly recognised in practice.

As a general rule, pledged shares must be enforced through a public auction. However, such auction is not necessarily conducted through court enforcement.

Any prior agreement stating that the pledgee will automatically become the owner of the pledged shares upon default is void and unenforceable.

To enforce a pledge, the pledgee must first send a written notice to the debtor demanding payment within a specified period. If the debtor fails to pay, the pledgee may proceed with enforcement by public auction, provided that the pledgor is notified of the time and place of the auction.

Non-judicial foreclosure is available only if the mortgagor sends a written notice to the mortgagee requesting a public auction of the mortgaged property, and there are no other registered mortgages or registered preferential rights over the same property. Such notice is treated as the mortgagor’s consent to the auction. Upon receiving the notice, the mortgagee must carry out the public auction within one year.

A mortgagor (or debtor) generally has a right of redemption to repay the debt and recover the mortgaged property. This right exists before foreclosure is completed – ie, before a court judgment is rendered.

Under Thai law, a lender may pursue multiple remedies at the same time. A lender may:

  • file a court claim to enforce against the mortgaged property and pledged shares; and
  • at the same time, pursue a personal claim against the borrower for payment of the debt.

Pursuing foreclosure and a debt claim in parallel does not impede the borrower’s or mortgagor’s right of redemption.

The timeline for completion of the sale and transfer of the property varies, as it depends on the availability and scheduling of the relevant office of the Legal Execution Department, which is the state agency responsible for executing judgments. In practice, it can be expected to take at least two years from the filing of the case until the property is listed for public auction.

If transfer of ownership of the mortgaged property to the mortgagee is permitted under the conditions described in 2.1 Foreclosure Process, the transfer can be completed after the court judgment is rendered, which typically takes approximately 12 to 18 months from the filing of the case.

If a mortgaged property is sold by public auction and the net proceeds are less than the outstanding debt, Thai law generally relieves the debtor from liability for the remaining shortfall. However, the parties may agree otherwise by contract, and in practice lenders commonly require the debtor to remain liable for any shortfall.

The most commonly used structure for real estate joint ventures in Thailand is a private limited company, which facilitates equity participation, shareholder agreements and board-level governance. To implement this structure and ensure mutual co-operation, the partners typically enter into a joint venture agreement and/or shareholders’ agreement setting out funding arrangements (through equity and/or shareholder loans), corporate governance, management structure, the roles and responsibilities of each party, profit-sharing mechanisms and exit options.

In addition, ancillary service agreements are often entered into to govern operational, management or technical services provided to the joint venture company.

Duties of joint venture partners in Thailand arise primarily from the joint venture or shareholders’ agreement and general company law under the Civil and Commercial Code. Key statutory duties include the obligation to act in good faith and not to abuse majority voting power, and, where applicable, the statutory duties of directors or managing partners to act with care and loyalty, and in compliance with law and the company’s constitutional documents.

Remedies for violation typically depend on the contractual framework and may include damages and contractual exit mechanisms such as put or call options under the joint venture agreement.

From a real estate perspective, joint venture structures must also comply with foreign ownership restrictions. In broad terms, Thai law restricts foreign ownership of land and limits foreign participation in certain real estate-related businesses. These restrictions influence joint venture structuring and, if breached, may result in regulatory sanctions or challenges to the legality of the arrangement.

Where a joint venture’s governing documents are silent or unclear, or result in a management deadlock, disputes are resolved by reference to statutory default rules, good-faith principles and the prohibition on abuse of rights under the Civil and Commercial Code.

In particular, Section 75 of the Civil and Commercial Code may apply where a partner exercises voting rights or veto powers, or refuses to co-operate solely to cause injury or to obstruct the joint venture, in which case the aggrieved partner may apply to the court to request the appointment of a temporary representative to act on behalf of the obstructing partner or the company for specific acts necessary to prevent harm or enable essential decision-making.

Under Thai law, automatic entry of judgment or provisional remedies is not available.

Winding down a real estate joint venture in Thailand requires compliance with formal statutory dissolution and liquidation procedures, including creditor notification and settlement prior to asset distribution, as well as adherence to any exit or liquidation provisions in the joint venture or shareholders’ agreement.

Particular care is required where the joint venture holds real property, as transfers of land must be registered at the Land Office and comply with foreign ownership restrictions under the Land Code.

In Thai real estate finance transactions, the most commonly encountered forms of security are mortgages over real property and pledges of shares in the project company. Where the borrower is not the owner of the real property and holds only possessory or usage rights under a lease agreement, Thai law provides a specific form of security over such rights – namely, a business security under the Business Security Act. In such cases, lenders typically require the borrower to register the lease agreement as business security.

In Thailand, most real estate financing is carried out on a recourse basis. In certain cases, guarantees by project sponsors, major shareholders or parent companies are required to enhance credit support for the financing. In addition, corporate support or sponsor undertakings are sometimes used in Thai practice as an alternative or supplement to formal guarantees, particularly in group financings. These undertakings generally involve a parent or affiliate agreeing to maintain the borrower’s solvency, liquidity or financial capacity to meet its obligations, rather than assuming direct payment liability.

As noted in 4.1 Types of Guarantees, most real estate financing is carried out on a recourse basis.

Under Thai law, the enforceability of guarantees is subject to mandatory statutory requirements under the Civil and Commercial Code. A guarantee must clearly specify the scope of liability, the maximum guaranteed amount and the duration in order to be enforceable.

A guarantor’s liability is generally secondary, requiring the creditor to first demand performance from the principal debtor before enforcing the guarantee. The creditor must also give the guarantor timely notice of the debtor’s default within the statutory period, failing which the guarantor’s liability may be discharged. In the case of personal guarantees, provisions attempting to characterise the guarantor as a co-debtor are invalid where they contradict mandatory statutory protections.

Under Thai law, no expedited judicial procedures are available for the enforcement of guarantees.

When a debtor defaults, the creditor must send a written notice to the guarantor within 60 days from the date of default. Otherwise, the guarantor is released from liability for interest, damages for default and other ancillary obligations, to the extent such amounts arise after the 60-day period expires.

Parallel enforcement of guarantees and underlying obligations is permissible.

In the Thai context, a “receiver” generally refers to an official receiver, who is a state official responsible for managing and distributing a debtor’s assets in bankruptcy proceedings.

In the case of a solvent company, an independent fiduciary may be appointed to act as a liquidator and carry out the company’s liquidation. By contrast, an insolvent liquidation must be brought before the court to place the debtor into bankruptcy. The process following a receivership order is handled by the official receiver. Such asset management is conducted under judicial supervision.

The official receiver is appointed in the bankruptcy proceedings to collect, manage and distribute the debtor’s assets.

Thai law does not provide a specific bankruptcy procedure for single-asset entities.

If a debtor that is a juristic person (such as a corporation) becomes insolvent and owes determinable debts of at least THB2 million to one or more creditors, the creditor(s) may commence bankruptcy proceedings by filing a claim with the court.

A bankruptcy filing itself does not affect the legal status of the debtor, nor the lender’s right to enforce claims against the debtor or its guarantor. However, once a receivership order is issued, the lender may no longer enforce against the debtor’s assets through ordinary proceedings. To recover outstanding debts, the lender must instead file a claim for debt repayment with the official receiver.

Notwithstanding the above, secured creditors are entitled to enforce their security without filing a claim for repayment in the bankruptcy proceedings. However, if the proceeds from enforcing the security do not fully cover the outstanding debt, the secured creditor must file a claim for repayment in order to recover the shortfall.

Secured creditors include creditors who have rights over the debtor’s property by virtue of a mortgage, a pledge, a right of retention or a preferential right that may be enforced in a manner similar to a pledge.

As a side note, once a debtor commences bankruptcy proceedings, this typically triggers an acceleration of the loan, entitling the lender to demand immediate repayment.

For transactions that directly involve real estate, such as land sale and purchase agreements or lease agreements, disputes are typically resolved through the Thai courts, particularly where enforcement must be carried out locally in Thailand.

Arbitration clauses are commonly used for agreements that are not directly linked to the property itself, particularly where the transaction involves foreign investors or where parties seek neutrality and international enforceability, such as joint venture agreements for real estate projects, even though the governing law is Thai law. In such cases, the most commonly used arbitration rules and venue are those of the Singapore International Arbitration Centre (SIAC).

Arbitration offers several advantages in Thai real estate transactions, particularly in cross-border deals, including neutrality, the ability to appoint specialist arbitrators, confidentiality, and the international enforceability of awards. Arbitration may also be perceived as being less conservative and more flexible than litigation before Thai courts, particularly in complex commercial or joint venture disputes. However, arbitration has limitations in asset-based real estate disputes, as arbitral tribunals lack direct coercive authority over land registration, foreclosure and other remedies requiring action by the Land Office or court execution authorities.

By contrast, litigation before Thai courts offers practical advantages in disputes involving real property, as courts have direct authority over land, foreclosure, registration and interim relief affecting assets, which is more readily enforceable. Accordingly, arbitration is generally better suited to non-asset-related disputes, such as joint venture or contractual disputes, while litigation is more effective for asset-based disputes requiring enforcement against real property.

Mediation is not widely used as a primary dispute resolution mechanism in Thailand. In practice, most real estate disputes are resolved through direct negotiation, arbitration or court proceedings.

Thai courts may grant provisional remedies to protect parties’ rights while a real estate dispute is pending. When filing a court complaint, or at any time prior to the judgment, an application for provisional remedies may be submitted to the court.

A temporary injunction may be ordered to:

  • maintain the status quo of the parties; or
  • prevent actions that could cause irreparable harm before the court issues a final judgment.

In the context of real estate dispute, courts may grant an injunction that:

  • prohibits the sale or transfer of real property;
  • prohibits the creation of mortgages, leases or other encumbrances over the property; or
  • restrains eviction or termination of possession in appropriate cases.

When a party requests the court to issue a provisional order to freeze or secure property, the court must be satisfied that:

  • the defendant intends to move, transfer, sell or dispose of the disputed property (or their assets) to place it beyond the court’s reach; or
  • the defendant intends to delay or obstruct enforcement of a future judgment.

When a party requests the court to issue a temporary injunction to restrain conduct, the court must be satisfied that:

  • the defendant intends to repeat or continue the wrongful act, breach of contract, or conduct being sued upon;
  • the plaintiff will continue to suffer harm as a result of the defendant’s actions;
  • the disputed property or the defendant’s assets are at risk of being wasted, damaged or transferred to others; or
  • there are circumstances showing an intention to evade enforcement or demonstrating necessity, as described above.

The risks of improper use of provisional remedies are relatively low in practice, as Thai courts apply strict scrutiny when deciding whether to grant such remedies and generally limit the scope of any provisional measures ordered.

Thai courts are willing to grant provisional remedies where it can be shown to the court’s satisfaction that the defendant’s actions may cause ongoing harm, frustrate enforcement or render a final judgment ineffective.

Irreparable harm may be established by showing that the disputed property is at risk of being damaged, demolished or transferred to others.

Thai law does not recognise a mechanic’s lien or statutory construction lien that can be registered over real property without a court order. Instead, Thai law recognises a right of retention (possessory lien), which:

  • applies only if the contractor or vendor is lawfully in possession of the property or materials; and
  • allows the contractor to retain possession until payment is made.

If the contractor does not have possession, no lien right arises, and payment must be pursued through legal action.

REITs in Thailand are governed primarily by two key statutes: the Trust for Transactions in the Capital Market Act and the Securities and Exchange Act, with the Securities and Exchange Commission of Thailand serving as the principal regulatory authority. However, in the event of litigation, these statutes do not prescribe any specific dispute resolution or procedural framework, and general law therefore applies.

There has been growing public interest in the real estate sector, particularly with respect to sustainability, regulatory compliance and safety standards. In response to these developments, REITs in Thailand are subject to enhanced disclosure expectations, including increased disclosure on environmental, social and governance-related matters.

Real Estate Litigation Risks and Commercial Implications: Termination of the Urbana Property Fund

The Urbana Property Fund (URBNPF) is a Thai property fund established to invest in long-term leasehold rights in premium real estate assets in Thailand. Its principal investment is a long-term leasehold interest in Urbana Langsuan, a high-profile condominium located in the heart of Bangkok – an area characterised by strong demand, strategic importance and high property values. As is typical of property funds structured around leasehold interests, the viability of URBNPF depends fundamentally on the enforceability and stability of its contractual framework, particularly the master lease with the landowner and the sublease arrangements through which operating income is generated.

URBNPF is now facing circumstances that place these contractual relationships, and the fund itself, under severe strain. Kiatnakin Phatra Asset Management Company Limited, acting as the fund manager, has disclosed that the fund may be subject to termination following a potential cancellation of its leasehold agreement by the lessor in 2025. Under the fund’s constitutive documents and applicable regulations, termination of the leasehold rights would constitute a trigger event requiring dissolution of the fund.

At the centre of this dispute is the fund’s income structure. URBNPF does not operate or manage the property directly; instead, it relies on rental income from a sublessee, Urbana Estate Company Limited, which subleases the property from the fund and conducts the underlying business operations. This layered leasing structure is commonly used in property funds and REITs, as it allows funds to avoid operational risks. However, from a litigation and enforcement perspective, it also creates a chain of interdependent contractual obligations, where a breach at one level can have immediate and potentially irreversible consequences at another.

The dispute arose when URBNPF received formal notice that the sublessee had ceased making rental payments. As a result, the fund was unable to pay the lease rental due to the lessor within the contractual deadline. Under Thai lease law and the relevant leasehold agreement, failure to pay rent within the specified period may entitle the lessor to terminate the lease. Once termination occurs, the leasehold rights revert to the lessor, leaving the fund without any income-generating asset.

From a litigation perspective, the fund’s exposure is multifaceted. First, URBNPF may have contractual claims against the sublessee for breach of the sublease agreement, including claims for unpaid rent, damages and possibly termination. However, pursuing such claims through litigation or arbitration is unlikely to provide immediate relief. Real estate disputes are often protracted, particularly those involving eviction, damages or complex commercial arrangements. Even if the fund were to obtain a favourable judgment, enforcement against a financially distressed sublessee may be difficult or yield limited practical recovery.

Second, the fund faces the risk of enforcement action by the lessor. While the lessor’s contractual right to terminate the lease may be relatively clear, disputes may nonetheless arise in relation to compliance with notice requirements, the availability of any cure periods, or the interpretation and application of force majeure or hardship clauses, if any are included in the lease.

A key legal complication is the fund’s apparent inability to remove the defaulting sublessee and secure a replacement within a short timeframe. Eviction proceedings under Thai law require strict compliance with statutory procedures, and typically involve court processes. During this period, the fund remains contractually obliged to pay rent to the lessor, regardless of whether or not it is receiving any income from the sublessee. This misalignment between litigation timelines and ongoing payment obligations significantly increases the fund’s risk exposure.

The consequences of lease termination are particularly severe for a leasehold-based fund. According to disclosures by the fund manager, termination of the leasehold agreement would reduce the fund’s net asset value (NAV) to zero. Unlike freehold interests, leasehold rights do not retain residual value once the lease is terminated. From a legal perspective, this means that even successful litigation against the sublessee may not restore value to investors if the primary lease has already been lost.

This situation illustrates a classic cascading default scenario in real estate transactions. An initial breach by the sublessee leads to a secondary breach by the fund, which in turn enables enforcement action by the lessor. While URBNPF may seek to argue that the breach resulted from circumstances beyond its control, Thai contract law generally does not excuse the failure to pay rent on the basis of a third party’s default, absent specific contractual protections. As a result, the fund ultimately bears the legal and financial consequences of the sublessee’s failure.

Another important litigation-related issue concerns the lessor’s approach to rental payment enforcement. There is an open question as to whether the lessor will adopt a stricter policy requiring full and timely payment without flexibility in response to this situation. If such an approach is taken, the scope for negotiation, restructuring or standstill arrangements may be limited. For property funds holding long-term leasehold rights from public or quasi-public entities, the lessor’s enforcement posture can be as significant in practice as the express terms of the lease itself.

In conclusion, the potential termination of URBNPF highlights the significant litigation and enforcement risks inherent in leasehold-based real estate investment structures. Despite holding rights in a prestigious property in a prime Bangkok location, the fund’s continued viability depends on the enforceability and performance of interconnected contractual arrangements. The case serves as a cautionary example for investors, fund managers and legal practitioners, underscoring the importance of robust contractual protections, proactive dispute management and a realistic assessment of litigation timelines in property fund and REIT structures.

While the URBNPF case highlights structural vulnerabilities within leasehold-based investment vehicles, litigation risk in Thailand’s real estate sector is not confined to contractual interdependence. Recent developments in building control and environmental compliance reflect a parallel shift toward intensified judicial scrutiny, as detailed below.

Heightened Scrutiny of Building Permits and Construction Compliance in Thailand: Key Considerations for Foreign Investors

Foreign investors in Thailand’s real estate, hospitality and infrastructure sectors are operating in a regulatory and litigation environment that has changed materially. In recent years, Thai courts and regulatory authorities have adopted a significantly stricter approach to building permits, Environmental Impact Assessment (EIA) approvals and construction compliance. High-profile construction accidents and landmark administrative court decisions have made it clear that the mere existence of formal approvals does not, by itself, shield projects from legal or regulatory risk.

For foreign investors, who typically rely on local partners, consultants and representations made by relevant authorities, this shift substantially elevates execution risk, enforcement risk and downside exposure, even in respect of projects that appear to be fully permitted. A more conservative, compliance-driven investment and development strategy has therefore become essential.

Background: a shift toward substantive regulatory scrutiny

Historically, Thailand’s regulatory environment was often perceived as being permit-centric and largely procedural, with the issuance of approvals regarded as a critical milestone for risk mitigation. While this perception was never entirely accurate, recent judicial and enforcement developments demonstrate a clear departure from a formalistic approach.

Thai courts have increasingly examined whether:

  • all statutory conditions for permit issuance were genuinely satisfied;
  • supporting documentation (eg, land surveys, road-width certifications, engineering calculations and EIA assumptions) was factually accurate; and
  • construction and project execution strictly complied with the scope and assumptions underpinning the approvals.

At the same time, regulators (particularly local administrative authorities) have become more proactive in inspections, enforcement actions and co-operation with investigative bodies. This has resulted in a greater likelihood of post-approval challenges, including litigation initiated by third parties such as local residents, competing property owners or public interest groups.

Catalysts for increased scrutiny

SAO building collapse (March 2025)

Public and regulatory attention intensified following the collapse of a 30-storey high-rise under construction for the State Audit Office of Thailand (SAO) in Bangkok in March 2025, which occurred after a major earthquake in Myanmar. Although the natural disaster was a triggering factor, the incident prompted wider examination of:

  • structural design assumptions;
  • construction supervision and compliance with approved plans; and
  • the robustness of regulatory oversight mechanisms.

For foreign investors, the key implication is that external events (such as natural disasters) can quickly expose underlying compliance deficiencies and lead to retrospective regulatory review and investigation.

Rama II Road construction accidents in 2025

In parallel, a series of construction-related accidents in 2025 involving elevated expressway and bridge projects along Rama II Road (a major logistics corridor connecting Bangkok with southern Thailand) reinforced public concern over construction safety and enforcement standards.

These incidents heightened political and administrative sensitivity to construction risk, and resulted in:

  • increased site inspections;
  • a greater readiness to issue stop-work orders; and
  • stronger public expectations that authorities and courts will intervene decisively where non-compliance is identified.

Core legal framework affecting foreign investors

Building Control Act

The principal statute governing construction in Thailand is the Building Control Act B.E. 2522 (1979), supplemented by ministerial regulations and local administrative rules. The Act regulates the construction, alteration, use and demolition of buildings, with a strong focus on public safety and urban order.

Local administrative authorities, such as the Bangkok Metropolitan Administration (BMA) and provincial municipalities, are responsible for issuing building permits and supervising compliance. These authorities exercise administrative discretion, and their decisions may subsequently be subject to review by the Administrative Courts.

For foreign investors, reliance on local approvals without independent verification has become increasingly risky, as errors or misinterpretations by authorities do not necessarily shield developers or owners from adverse judicial outcomes.

Environmental Impact Assessment

The Enhancement and Conservation of National Environmental Quality Act B.E. 2535 (1992) introduces an additional layer of regulatory complexity. Projects falling within prescribed categories, based on type, size or location, must obtain EIA approval before a building permit can be lawfully issued.

EIA approval is:

  • project-specific and assumption-based;
  • procedurally intensive, with mandatory public participation; and
  • particularly vulnerable to challenge before the Administrative Courts.

For foreign investors, EIA risk is often underestimated. In practice, defects in EIA assumptions, data accuracy or public consultation can invalidate downstream approvals, even years after construction has commenced.

Documentation risk: lessons from Aetas Ruamrudee

The Aetas Ruamrudee case illustrates how documentation risk can crystallise into catastrophic outcomes. The project comprised a 24-storey hotel and an 18-storey residential building on Ruamrudee Alley in central Bangkok. The dispute arose from challenges to the building permit based on road-width requirements under the Building Control Act.

The developer relied on official certification issued by the district office confirming that Ruamrudee Alley met the minimum width required for high-rise development. However, court-ordered land surveys later revealed that certain sections of the road were narrower than the statutory threshold.

Despite the developer’s reliance on official documentation, the following actions arose:

  • the Central Administrative Court ordered demolition of the building;
  • the Supreme Administrative Court upheld the demolition order; and
  • subsequent damages claims against the authorities for certification errors were dismissed in November 2025.

Key implications for foreign investors

  • Reliance on official certifications does not guarantee protection.
  • Courts prioritise objective factual compliance over administrative representations.
  • Liability and loss may ultimately rest with the project owner or investor, regardless of how fault is allocated under contractual arrangements.

Revocation risk: 125 Sathorn

The 125 Sathorn case further underscores the risk of retroactive revocation of permits and EIA approvals. The project involved a luxury condominium development on subdivided land on Sathorn Road in central Bangkok.

Following challenges brought by neighbouring property owners, the Central Administrative Court revoked both the building permit and the EIA approval in October 2023, finding that:

  • following land subdivision, the project no longer met statutory thresholds; and
  • the assumptions underlying the approvals were therefore invalid.

Although the developer has appealed to the Supreme Administrative Court, the project remains effectively stalled. For foreign investors, this case demonstrates that:

  • changes in land configuration or project parameters can invalidate prior approvals;
  • third-party litigation risk is particularly acute in dense urban areas; and
  • even premium, centrally located developments are not immune from judicial intervention.

Key risks unique to foreign investors

Foreign investors face several structural disadvantages in this environment, including:

  • limited familiarity with local administrative practices;
  • reliance on Thai partners or consultants;
  • language and cultural barriers in public consultations and community engagement; and
  • reduced ability to influence post-approval enforcement dynamics.

In addition, foreign investors may face reputational risk extending beyond Thailand, particularly where projects attract media attention or public opposition.

Practical risk mitigation strategies

Foreign investors should consider adopting the following measures.

  • Enhanced regulatory due diligence:
    1. independent verification of zoning, road access and physical site conditions;
    2. cross-checking EIA assumptions against actual design specifications and on-site conditions; and
    3. stress-testing permit validity under worst-case litigation scenarios.
  • Contractual risk allocation:
    1. robust representations and warranties from developers and contractors;
    2. indemnities for permit and EIA defects (recognising enforcement limitations); and
    3. step-in rights and termination triggers linked to regulatory outcomes.
  • Ongoing compliance monitoring:
    1. ongoing review of construction works against approved plans;
    2. formal documentation of design changes and related regulatory approvals; and
    3. proactive engagement with relevant authorities and stakeholders.
  • Investment structuring:
    1. phased capital deployment aligned with regulatory milestones;
    2. conservative valuation assumptions that reflect regulatory risk; and
    3. exit planning that accounts for potential delays or enforcement action.

Conclusion

Thailand remains an attractive destination for foreign investment in real estate, hospitality and infrastructure. However, the regulatory landscape governing building permits and construction compliance has become materially more stringent and, in certain respects, less predictable.

Recent court decisions and enforcement actions demonstrate that formal approvals no longer provide reliable protection against legal or regulatory challenge. For foreign investors, success increasingly depends on a thorough understanding of the regulatory framework, conservative structuring and proactive compliance management throughout the life of the project.

A compliance-driven approach is no longer optional. It is now a core element of prudent investment practice.
