Using a Thai Marriage Certificate Abroad — Translation, Legalisation, Apostille

Kor Ror 2 is the marriage register — the registrar's record signed by the spouses and witnesses. Kor Ror 3 is the marriage certificate handed to the couple. For use abroad, foreign authorities usually want a certified copy of the Kor Ror 2 because it carries fuller particulars than the certificate.

That depends on that country's law. Many states recognise a divorce validly effected where the marriage was registered, while others require the record to be transcribed or confirmed by a court first. Obtain the Kor Ror 7 plus a certified copy of the divorce register, translate it into the destination language and complete the legalisation chain.

Thailand has acceded to the HCCH 1961 Apostille Convention, which enters into force for Thailand on 28 February 2027. Until then, Thai documents for overseas use still need the two-step chain: certification by the Department of Consular Affairs, then legalisation by the destination country's embassy. Follow official notices at consular.mfa.go.th and hcch.net.

Report the birth at the local district office where the child was born within 15 days, using the hospital's certificate of birth (Tor Ror 1/1), the Thai mother's ID card and the foreign parent's passport. Then obtain an English-language birth certificate or certified copy for the consular report of birth at the other country's embassy.

Either a single-status certificate issued by the Chinese registry authority and authenticated (China joined the Apostille Convention in November 2023, so an apostille is accepted) or a declaration made at the Chinese Embassy in Thailand. It is then translated into Thai and legalised by the Department of Consular Affairs. To use the Thai marriage certificate in China, have it MFA-legalised and then authenticated by the Chinese Embassy.

The Russian party obtains a status declaration at the Russian Embassy in Bangkok or the Consulate General in Phuket, then has it translated into Thai and legalised by the Department of Consular Affairs. To use the Thai marriage certificate in Russia, translate it into Russian, obtain Thai MFA legalisation, and then have it authenticated by the Russian Embassy — Thailand is not yet an Apostille member, so the two-step chain always applies.

Yes. Have the foreign marriage certificate authenticated (apostille or Thai embassy legalisation), translated into Thai, the translation legalised by the Department of Consular Affairs, then file a family status record (Kor Ror 22) at a district office. Only then can you change your title and surname and rely fully on Thai marital property and inheritance rules.

Request the certified copy (Kor Ror 2) and the certificate (Kor Ror 3) from the district office, translate them into English or the destination language, have the translation legalised by the Department of Consular Affairs, then authenticated by the destination country's embassy in Thailand. Countries that require a certified translator — Australia (NAATI) or EU sworn translators — need that additional step.

Sign an affidavit or statutory declaration of marital status before your consular officer in Thailand, or before a notary at home with an apostille. The document is then translated into Thai and the translation legalised by the Department of Consular Affairs before the district office will accept it. Most documents are treated as current for three to six months, so plan the sequence tightly.

Obtain certified copies from the district office, have them translated into the destination language, legalise the translation at the Department of Consular Affairs, and then either apostille or legalise at the destination embassy depending on that country's rules. Many civil-law countries also require the marriage to be recorded with their own civil registry before spousal visa rights apply.
