Expert testimony is permitted in cases where scientific, artistic, technical or practical knowledge may be necessary to prove any facts or circumstances that are relevant to the matter at issue.
The parties can appoint an expert themselves or ask the court to appoint an expert to present the requested report. If neither party deems the appointment of an expert necessary, the court itself may not appoint an expert. The only exception to this rule is during proceedings that concern the declaration or contest of kinship, paternity or maternity, the capacity of an individual or during matrimonial proceedings. In these situations the court is allowed, by the SCPA, to appoint ex officio an expert to issue an opinion.
