Ceremony versus registration
Thai law recognises a marriage only once it is entered in the register at a district office. Many couples hold a traditional ceremony, but without registration there is no legal marriage for immigration, property or inheritance purposes. Registration can take place before or after a ceremony.
Documents commonly required
- Passport of the foreign partner, with the current entry stamp or extension.
- Affirmation or certificate of freedom to marry, issued by the foreign partner's embassy in Thailand or by the home authority, depending on the country.
- Certified Thai translation of that document, legalised by the Department of Consular Affairs.
- Thai partner's ID card and house registration book.
- Divorce decree or death certificate of a former spouse, where applicable, with translation.
- Two witnesses, and an interpreter if the foreign partner does not speak Thai.

Legalisation now and after the Apostille change
Today, foreign documents used in Thailand are legalised: issued or certified by the home authority, legalised by the Thai embassy abroad where needed, and then legalised by the Department of Consular Affairs in Bangkok. Once the Apostille Convention takes effect for Thailand on 28 February 2027, documents from other Convention states can carry an apostille instead of consular legalisation. Thai translations will still be needed, and district offices may take time to adjust their practice.
After registration
Ask for the marriage certificate (Kor Ror 3) and the marriage register extract (Kor Ror 2), and have certified translations prepared if you need them abroad. Registering the marriage in your home country is a separate step governed by its own rules. For a marriage visa or extension, immigration will usually ask for these documents together with financial evidence and proof of the relationship.
Common problems
- Names that are spelled differently across the passport, embassy document and Thai translation.
- A previous divorce that is not finalised or not documented.
- Embassy appointment lead times that delay the freedom-to-marry document.
- Assuming the ceremony alone makes the marriage valid.
How we help
We check which document your embassy issues, arrange certified translation and Consular Affairs legalisation, prepare the district office file and attend with you as interpreter where useful. The district registrar decides whether to register the marriage; no adviser can promise acceptance of a document.
