Signed 3 months before wedding — is it valid?

Not yet. It only takes effect once entered into the marriage register on the same day as the marriage registration at the amphur. Otherwise void.

Can we amend it later?

Only by court order (§1467). Draft carefully the first time.

Will foreign jurisdictions recognise it?

We prepare MFA-legalised bilingual originals plus onward Apostille/legalisation as needed.

Drafting THB 15,000–45,000 (complexity) + bilingual translation 3,000–8,000 + MFA 800/copy + amphur registration free.

Prenuptial Agreement — Thai × Foreigner

สัญญาก่อนสมรส — คนไทย × ชาวต่างชาติ

Quick Answer

Bilingual prenup drafted, registered at the same amphur on marriage day, clearly ring-fencing separate property to prevent 50/50 division on divorce — from THB 15,000.

Timeline: Draft 3–5 business days · 2 revision rounds · register at the amphur on the marriage day.

Legal Basis

Thai Civil & Commercial Code §1465–1469 — a prenuptial agreement must be in writing, signed by both spouses and two witnesses, and entered into the marriage register at the amphur ON THE DAY OF MARRIAGE REGISTRATION. Failure voids it under §1466.

Who it is for

Couples where one party is Thai and the other is a foreign national; needing pre-marriage asset segregation (pre-owned condo/house, foreign bank accounts, company shares).

Key Clauses

Schedule A — separate property (condo, land, vehicles, accounts, shares, IP)
Fruits of separate property (rent, dividends) remain separate
Management & disposal of community property
Pre-marriage debt — each spouse solely responsible
Thai-law governing clause + certified English translation

Documents

Thai ID + house registration / foreign passport
Title deeds, condo sale contracts, 6-month bank statements, payslips
Pre-marriage asset & liability schedule (we provide template)
2 witnesses (we can arrange)

Pitfalls

Signed AFTER marriage registration → completely void (§1466)
English-only text without a Thai translation → registrar will refuse to enter it
Manifestly unfair to one spouse → court may re-open under §1467
Assets omitted from Schedule A → presumed sin-somros (community) and split 50/50
