Q1350. What is a prenuptial agreement under Thai law and how is it registered?

Answered by the NYC Visa & Translation team

Thai law recognises prenuptial agreements under the Civil and Commercial Code, with important conditions: (1) it must be in writing and signed by both parties; (2) it must be registered with the marriage registrar at the same time as the marriage registration — an agreement made after the marriage is not effective as a prenup; (3) the content must not be contrary to public order or good morals; (4) amendments after registration require court approval. For Thai–foreign couples, a prenup clearly defines how personal and marital property is managed, which is especially valuable when assets sit in several countries. It should be drafted bilingually (Thai–English) by a specialist and checked against the law of any country where assets are held. Our lawyers draft and register bilingual prenuptial agreements end to end. This is general guidance; requirements and fees change — always verify with the district office, the Ministry of Foreign Affairs, Thai Immigration, or the Department of Employment before proceeding.
