Prenuptial Agreement in Thailand — Enforceable Under Thai CCC
A Thai prenuptial agreement under CCC §1465 must be in writing, signed by both spouses + 2 witnesses, and registered together with the marriage certificate — if registered later, it is void. NYC drafts a bilingual TH-EN agreement and provides an attorney witness at any Amphur.

Quick answer
Thai prenups require a written document, spousal + 2-witness signatures, and same-day registration on the marriage certificate. Post-marriage prenups are void. NYC prepares a bilingual agreement covering separate property, marital property, business rights, and overseas assets — attorney witness included from THB 12,900.
Allowed / not allowed
Allowed: separate vs marital property split, business ownership, real-estate distribution, overseas assets. Not allowed: child custody (decided at divorce), pre-agreed maintenance, other heirs' inheritance.
Cross-border couples
Where nationalities differ, NYC sets governing law = Thai law + choice of court = Thailand, and recommends a mirror agreement in the foreign spouse's country. US/UK courts sometimes recognise a Thai prenup via conflict-of-laws — case-by-case assessment.
Amendments
CCC §1467 forbids amending a prenup after marriage without court order — everything must be in v1. NYC uses a 45-item checklist covering all asset classes.
Financial disclosure
Unlike US practice, Thai law does not mandate full disclosure, but NYC recommends Schedule A/B annexes listing assets/liabilities to prevent later claims of concealment.

FAQ
Post-marriage prenup?
Void. You can sign an inter-spousal agreement, but either spouse can revoke it at will — no long-term certainty.
Any Amphur?
Yes — nationwide. Bangkok/Metro included; upcountry adds travel.
Foreign spouse — translate?
Translate into a language the spouse understands + Amphur interpreter if needed. NYC provides interpreter at THB 3,500.
Effect on divorce?
Court applies the prenup for property division unless it offends public order or good morals.
Overseas use — Apostille?
Yes — obtain a certified Amphur extract (Khor.Ror.2/3), attorney-CTC, then MFA Apostille.
