Marriage Registration in Thailand (Foreigner × Thai)

What Thai law requires before a district office will register a marriage

Marriage in Thailand is constituted by registration at an Amphur or Khet district office under Book V of the Civil and Commercial Code and the Act on Registration of Families B.E. 2478 (1935). A ceremony, however elaborate, creates no legal status by itself. Both parties must be at least seventeen years old, must not be within the prohibited degrees of relationship, must not be currently married, and must consent freely before the registrar.

For a foreign national the gating document is an affirmation of freedom to marry issued or notarised by their own embassy in Thailand. The embassy attests, on the evidence the applicant provides, that the applicant is free to marry under their national law. Each embassy has its own form and its own evidential requirements: some interview both parties, some require a recent single-status certificate from the home country, some accept a sworn declaration.

The affirmation is then translated into Thai and legalised by the Department of Consular Affairs of the Ministry of Foreign Affairs before the district office will accept it. Until Thailand's accession to the Apostille Convention enters into force on 28 February 2027, that MFA step is unavoidable, and an apostille obtained abroad does not replace it.

The document chain in sequence

1. Home-country evidence: Single-status certificate, decree absolute or death certificate of a former spouse, as your embassy requires; some embassies want these legalised at home first.
2. Embassy affirmation: Attend your embassy in Bangkok and obtain the affirmation of freedom to marry, in English or your own language.
3. Certified Thai translation: Translate the affirmation and passport data page into Thai; the translation must match the passport transliteration exactly.
4. MFA legalisation: Legalise the translated affirmation at the Department of Consular Affairs, Chaeng Watthana or a regional office.
5. District office registration: Both parties attend with passports, house registration for the Thai party, the legalised affirmation and two witnesses.
6. Marriage certificate and abroad recognition: Obtain the Kor Ror 2 certificate and, for use abroad, translate and legalise it back through MFA and the destination embassy.

Property consequences people underestimate

Registration creates the Sin Somros regime: property acquired during the marriage is marital property held in equal shares on dissolution, while property owned before the marriage or received during it by inheritance or personal gift remains Sin Suan Tua. Couples who intend a different arrangement must register a prenuptial agreement at the same time as the marriage. An agreement signed after registration is generally unenforceable, which surprises couples who plan to formalise finances later.

Marriage also affects a foreign spouse's immigration position, but not automatically. A Non-Immigrant O extension based on marriage to a Thai national requires its own evidence, including the income or bank threshold set by the applicable Immigration Bureau order, and marriage alone confers no right to stay or to work.

For dual-nationality couples the second question is recognition at home. Most countries recognise a Thai marriage registered under Thai law, but many require the Kor Ror 2 to be translated and legalised before it can be recorded in their own civil registry, and some require registration within a defined period.

Same-sex marriage after the 2024 amendment

The Marriage Equality Act amending the Civil and Commercial Code came into force on 22 January 2025, opening marriage registration to couples of any gender on the same terms, with the same rights as to marital property, inheritance and adoption. The district office process, the embassy affirmation requirement and the MFA legalisation chain are the same.

The practical variable for binational same-sex couples is the home country of the foreign partner. Where the partner's national law does not recognise same-sex marriage, that embassy may decline to issue an affirmation of freedom to marry, and the couple needs an alternative evidential route agreed with the district office in advance.

Common mistakes and how we avoid them

More questions we are asked

Do we need to be resident in Thailand to marry here?

No. Tourists may register, provided the embassy affirmation and legalisation chain are complete.

How long does the whole process take?

Commonly three to seven working days once the embassy appointment is available, most of it MFA legalisation turnaround.

Can the marriage be registered at any district office?

Yes, any Amphur or Khet may register, though offices differ in their comfort with foreign documentation.

Is a Thai marriage valid in my home country?

Generally yes if validly formed here, but most countries require a legalised translation of the Kor Ror 2 before recording it.

Does marriage give my spouse the right to work in Thailand?

No. A work permit and an appropriate visa category are still required.
