Best Affidavits & Statutory Declarations Lawyers in Thailand

1. About Affidavits & Statutory Declarations Law in Thailand

In Thailand, an affidavit is a written statement of fact that is sworn or affirmed before an authorized official. It serves as evidence in court or before government agencies when a party cannot appear in person. A statutory declaration is a similar document used for certain administrative or cross-border purposes, typically prepared as a formal declaration of facts under oath or legal affirmation.

Thai practice generally requires affidavits or declarations to be in Thai or properly translated and authenticated. Documents created abroad may need translation, legalization, or consular authentication before Thai authorities will accept them. Always confirm the exact requirements with a qualified legal professional before submission.

Key takeaway: Affidavits and declarations are widely used in civil and administrative processes in Thailand, but their admissibility and form depend on the issuing authority and the purpose of the document. When in doubt, engage a lawyer to review language, translation, and authentication needs.
