Legal recognition starts at the Amphur
A marriage is only legally recognised in Thailand once it is registered at a District Office (Amphur). The Buddhist or Western ceremony is socially important but has no legal effect by itself — it is the Kor-Ror 2 marriage certificate from the Amphur that proves the marriage to immigration, banks and consulates abroad.
Step 1 — Embassy affirmation
The foreign spouse must obtain an Affirmation of Freedom to Marry from their own embassy in Bangkok. The form names both parties and confirms the foreigner is single and legally able to marry. Most embassies require an appointment, photo ID and a fee of 30–80 USD.
Embassies issue this in English (or the embassy's official language). The affirmation must then be translated into Thai and certified at the Ministry of Foreign Affairs Legalisation Division in Chaeng Wattana — this step is mandatory; the Amphur will not accept an untranslated affirmation.
Step 2 — MFA legalisation
Walk-in legalisation at the MFA takes 2 working days for standard service or same-day for express (200 THB vs 800 THB). The MFA stamps both the original English affirmation and the certified Thai translation.
Step 3 — Amphur appointment
- Both parties present in person.
- Original passport(s) of the foreign spouse plus a copy of the photo and visa pages.
- Thai ID and tabien baan of the Thai spouse.
- Legalised affirmation and Thai translation.
- Two Thai-speaking witnesses (the Amphur often provides them informally).
- Optional pre-nuptial agreement — must be registered the same day as the marriage to be enforceable.
Step 4 — Recognition abroad
To use your Thai marriage certificate overseas (for spouse visas, name changes, or immigration sponsorship) you usually need it legalised again. The standard route is: certified English translation of the Kor-Ror 2 and Kor-Ror 3, then MFA Bangkok legalisation, then legalisation by your home embassy.
Some countries (UK, Australia) accept Apostille-style legalisation; Thailand is not yet a full Apostille convention country, so the embassy step is normally required.
