A Thai embassy or consulate can register a divorce by mutual consent if the marriage was registered under Thai law. Both spouses normally attend with two witnesses; if one spouse is in Thailand, two offices can each register their part, with papers sent via the Ministry of Foreign Affairs.
Who can register a divorce at a Thai embassy?
The embassy acts as a Thai registry office, so it applies Thai rules. The Royal Thai Embassy in Canberra, for example, registers a divorce only where the marriage was between two Thais, or a Thai and a foreigner, and was registered under Thai law.
- The divorce must be by mutual consent, with a written agreement.
- The marriage must have been registered at a Thai district office or at a Thai embassy or consulate.
- The Thai spouse must usually live within that embassy's consular area; each mission lists the regions it covers.
- For marriages registered before 5 June 2003, the Washington embassy asks the wife to show a Thai passport and civil registration evidence of her use of the husband's surname.
If you married under foreign law, the embassy cannot register your divorce. A local divorce must be recorded in Thailand as a family status registration, which the Washington embassy says is processed in Thailand only.
What documents do you need?
Requirements differ slightly between missions, so download the forms from your own embassy's website. A typical checklist:
- Application for registration of divorce, signed by both spouses
- Divorce agreement covering children, property, other matters and the wife's title after the divorce
- Original marriage certificate, or a copy certified by a district office
- Passport of each spouse, and Thai ID card or house registration showing the 13-digit number
- Local identification such as a driver licence, if the mission asks for it
- The divorce certificate of any earlier marriage
- Two witnesses with Thai ID cards or passports, and copies
Most missions want copies in advance. Washington asks for them at least 10 business days before the appointment, and Canberra asks for bookings at least seven working days ahead.
Do both spouses have to be present?
For a divorce at the embassy alone, yes: both spouses attend in person and sign before the consular registrar. The Canberra embassy lists the service as free.
If one spouse is in Thailand, use a divorce at different registry offices. Each spouse signs at their own office, and the divorce is complete only when the second office registers it.
| Who starts | Office 1 | Office 2, which issues the certificate |
|---|---|---|
| Spouse in Thailand | District office in Thailand; papers sent through the Ministry of Foreign Affairs | The embassy, which calls the spouse abroad to sign in person |
| Spouse abroad | The embassy; the Thai spouse and two Thai witnesses first sign the agreement before a district officer | District office in Thailand, which contacts the Thai spouse to complete it |
In both versions the other spouse's copy of the certificate travels back through the Ministry of Foreign Affairs.
Agree in writing, before anyone signs, which spouse starts and at which office. A two-office divorce is not complete until the second registration, so neither spouse should remarry or act on the divorce before that date.
When does the divorce take effect, and how is it recorded?
Under Section 1531 of the Civil and Commercial Code, a consent divorce takes effect on registration. When both spouses sign at the embassy, the Washington embassy issues the certificate the same day.
The embassy is itself a Thai registry office, so the registration is a Thai record. Ask the mission when it will appear in Thai civil registration, and keep the original certificate safe.
Will an embassy divorce be accepted in other countries?
Usually you will need a translation and legalisation, as with any Thai document. Thailand joins the Apostille Convention on 28 February 2027, which should simplify this for many countries.
One warning for the United States: the Washington embassy states that USCIS does not accept marriage or divorce registrations made through a Thai embassy or consulate, or divorces at different registry offices, for Green Card purposes.
Frequently asked questions
Can I sign through a power of attorney instead of attending?
Do not assume so. Missions describe the spouse abroad signing in person, and a two-office divorce is the usual solution when you cannot be in the same place.
Can the embassy change my surname after the divorce?
No. The Washington embassy says surname changes and family status updates after a divorce are processed in Thailand, although it can certify documents you need for that.
Can the embassy register a court divorce?
A Thai court judgment is registered at a district office in Thailand, which a representative can do for you. Ask your embassy if you need help with the power of attorney.
Is there a fee?
Canberra lists divorce registration as free. Fees for related services, such as certifying documents or postage, vary by mission.
Where should you start?
Check that your marriage was registered under Thai law and find the mission that covers your area. Then agree the divorce terms, prepare the agreement and send copies for checking.
If children or property are involved, have a Thai family lawyer review the agreement before signing. It is the document that governs both after the divorce.
