Q1067. What are the attestation requirements for foreign wills and testaments used in Thai estate administration?
Answered by the NYC Visa & Translation legalization desk
Attestation requirements for a foreign will depend on its place of execution, form, and intended use in Thai estate proceedings. Obtain the original will or a court-certified copy acceptable to the Thai court, together with any relevant foreign probate order and death certificate. Ask the responsible Thai embassy which signatures or seals require prior authentication and consular legalization. Arrange Thai translations in the form required by the court, and confirm whether further MFA certification is needed. Thai counsel should separately assess execution validity and whether a Thai estate-administration petition is necessary. A common pitfall is assuming a legalized will proves its substantive validity or replaces Thai court procedures. Verify the document requirements with the relevant Thai court before filing.
