Q1163. What attestation requirements apply to foreign prenuptial agreements?

Answered by the NYC Visa & Translation legalization desk

Attestation of a foreign prenuptial agreement is separate from whether that agreement is legally effective in Thailand. Ask the district office registering the marriage, or the court receiving the document, which authentication and translation requirements apply. For a Thai marriage registration, obtain advice on Thai prenuptial formalities before the marriage; foreign notarization alone does not satisfy those formalities. If required, have signatures notarized abroad, obtain the relevant national authentication and Thai consular certification, and arrange a complete Thai translation. Submit for Thai MFA legalization where the receiving office requires it. A common pitfall is assuming legalization allows a prenup to be added after marriage registration. Verify the filing requirements with the receiving district office or court and relevant consular authority before filing.
