Dernière mise à jour :
A Thai marriage certificate (ใบสำคัญการสมรส, form Kor Ror 3, aussi écrit Khor Ror 3 ou KR3) is the official document that the registrar at the district office (amphur) issues to each spouse when a marriage is registered in Thailand. Under Section 1457 of the Code civil et commercial a marriage exists only once it is registered, whatever ceremony was held, so the certificate is the proof that the marriage exists at all. Immigration, land officers, banks and courts all ask for it.

Kor Ror 3 versus Kor Ror 2 and 22
Three forms are easily confused. The marriage register (ทะเบียนสมรส, Kor Ror 2) is the record that the spouses and their two witnesses sign in front of the registrar; it stays at the district office. The marriage certificate (Kor Ror 3) is issued from that register, one original to each spouse, on the same day. It carries the registration number, the names, nationalities and dates of birth of the spouses, the office and date of registration, and the registrar’s signature and seal. Registration is done under the Civil Registration Act B.E. 2534 and recorded centrally, so a certified copy of the register entry can be obtained later from a district office if an original is lost.
Kor Ror 22 is different again. A marriage celebrated abroad and later recorded in Thailand is entered on the family status register (ทะเบียนฐานะแห่งครอบครัว), and the extract from that register is the Kor Ror 22. It does not create the marriage; it records a foreign marriage that already exists so that Thai authorities can rely on it.
Getting the certificate as a foreigner
The registration takes about an hour at the amphur or Bangkok district office (khet), and most offices now require an appointment booked one to three weeks ahead. A foreigner brings a passport, an affirmation of freedom to marry from their embassy, a Thai translation of it, and proof that any previous marriage ended. The affirmation and translation must be legalised at the Ministry of Foreign Affairs first; standard legalisation can take several weeks in 2026, with a fast-track option of about ten working days. The district office fee is under 100 baht. Two witnesses sign the register, and an interpreter is needed if a spouse does not read Thai. The steps are in the guide to marriage registration in Bangkok.
A Contrat prénuptial must be lodged at the same appointment and noted in the register, or it is void. Section 1466 allows two routes and a reader should know which one they are on: the terms are either written into the marriage register itself at the time of registration, or made as a separate written agreement signé par les deux époux et au moins deux témoins, annexed to the register, with a note in the register at the time of registration saying it is annexed. Miss either route and the agreement is void, however sound its contents.
A clause choosing your own country’s law will not survive. Section 1465 voids any clause in a prenuptial agreement that is contrary to public order or good morals, or that provides for the spouses’ property relations to be governed by the law of another country. Foreign couples often assume their home law can be carried into a Thai marriage by agreement. It cannot: register the marriage in Thailand and Thai law governs the property relations. A certificate without that note means none was registered.
What the certificate is used for later
The Kor Ror 3 is the core document for a visa de mariage extension based on a Thai spouse, for a spouse’s claim as héritier légal, for registering property, for a child’s birth certificate and for any divorce, contested or by consent. For use abroad it is normally translated and legalised at the Ministry of Foreign Affairs; from 28 February 2027 an apostille will replace the chain of legalisations for countries in the Hague Convention.
The common mistakes are treating a Buddhist or village ceremony as a marriage (it is not, without registration), losing the only original abroad without a certified copy, and assuming a foreign marriage appears in Thai records. A marriage registered overseas is valid in Thailand if valid where celebrated, but it is not in the Thai civil registry, so the amphur cannot divorce it by consent; that divorce goes through the Tribunal de la famille.
Foire aux questions
How do I get a copy of my Thai marriage certificate?
Apply at a district office (amphur or khet) with your passport and the registration details. The office issues a certified copy of the marriage register entry, since the registration is held in the central civil registration database. The original Kor Ror 3 handed over at registration is not reissued as such, but the certified extract serves the same purpose.
Is a Thai marriage certificate valid abroad?
Yes, once translated and legalised. The certificate is translated into the language of the destination country and legalised at the Ministry of Foreign Affairs, and often at the foreign embassy as well. From 28 February 2027 Thailand issues apostilles, which replace that chain for Hague Convention countries.
What is the difference between Kor Ror 2 and Kor Ror 3?
Kor Ror 2 is the marriage register signed by the spouses, the witnesses and the registrar, which stays at the district office. Kor Ror 3 is the marriage certificate issued from that register, one original to each spouse. Both carry the same registration number.

Last reviewed: 14 September 2026. Sections 1457, 1465 and 1466 of the Civil and Commercial Code were read in Thai and English from this site’s own statute library: section 1457 for the rule that a marriage is effected only on registration; section 1466 for the two formality routes that keep a prenuptial agreement alive, including the requirement of at least two witnesses on the annexed-agreement route; and section 1465 for the clauses that are void, including a clause choosing the law of another country to govern the spouses’ property. Not verified in this review: the Kor Ror 2, 3 and 22 form numbers and what each contains, the appointment and Ministry of Foreign Affairs legalisation timescales, and the district office fee, which are administrative practice rather than provisions of the Code.
