Q1025. Is Thailand marriage certificate accepted for Apostille?

Answered by the NYC Visa & Translation team

A Thai marriage certificate does not automatically qualify for an apostille; the correct authentication route depends on Thailand's current Convention status and the receiving country's requirements. Check the Hague Conference on Private International Law's Apostille Convention status table, including effective dates, and confirm the procedure with Thailand's Department of Consular Affairs. Where the Convention does not apply between the countries, the document generally follows a legalization route, potentially including destination-embassy authentication. Ask the receiving authority whether it needs the marriage certificate, marriage registration record, or both, and which translation format it accepts. Translating or notarizing a certificate is not the same as obtaining an apostille or completing consular legalization.
