Can Foreigners Legally Get Married in Thailand? The 2026 Answer

Last updated 23 Oct 2026

The short answer

Yes. A legal wedding in Thailand for foreigners has only one route: registering your marriage at a Thai district office (an amphur, or a khet in Bangkok). A beach, temple or resort ceremony on its own isn't legal: "a marriage is only legally valid if it is formally registered with the appropriate Thai authorities" (Australian Consulate-General Phuket, March 2026).

Who can marry: age, status and witnesses

According to Thailand's Department of Provincial Administration (DOPA) (registration guide):

• Age: both of you must be 18 or older (Civil and Commercial Code s.1448, as amended in 2025; Thai Department of Older Persons summary of the amendment). If either of you is under 20, you also need written parental consent, translated into Thai (U.S. Embassy Thailand).
• Status: neither of you can be married to anyone else.
• Witnesses: you need two.
• Where: you can register at any district office (amphur or khet), wherever you live.
• Same-sex couples: same-sex marriage has been legal in Thailand since 23 January 2025, when the Marriage Equality Act came into force (Thai Department of Older Persons).

Documents, step by step

Four steps for foreign couples. If you're two different nationalities, each of you goes through your own embassy (U.S. Embassy Thailand).

1. Get your embassy's "free to marry" document, in Thailand. Depending on your nationality, it's called a certificate of no impediment (CNI), an affirmation or an affidavit.
2. Translate it into Thai. Use a professional translator. There are services at or near the Ministry of Foreign Affairs.
3. Legalise it at the Ministry of Foreign Affairs (MFA). The Department of Consular Affairs certifies the document and the translation. Its offices (U.S. Embassy Thailand):
   • Bangkok (Chaeng Wattana Road): weekdays 08:30–14:30.
   • Chiang Mai (Provincial Hall): weekdays 08:30–16:30.
   • The MFA's own checklist says each affirmation of marital status must be no more than 6 months old (MFA checklist).
4. Register at a district office. Take:
   • your passports
   • the legalised documents
   • proof that any earlier marriage has ended
   • your two witnesses

   Each district office can ask for more, so call yours first (GOV.UK).

Rules by nationality: US, UK and Australia

• United States:
  • The US Embassy in Bangkok or the Consulate in Chiang Mai issues a notarised marriage/divorce affidavit, by appointment only. It costs US$50, plus US$50 for a certified passport copy if your district office wants one.
  • The embassy notes the affidavit is "a self-sworn statement, NOT a guarantee or certification of single status", so bring proof of any divorce.
  • Source: U.S. Embassy Thailand.
• United Kingdom:
  • You need a marital status affirmation and a certified copy of your passport: £50 + £25 = £75. Apply online, then attend the British Embassy in Bangkok.
  • Book the appointment at least 7 days after you apply. In peak periods, the wait can be up to 3 weeks.
  • The affirmation is only valid for the month and province you named when you applied.
  • Source: GOV.UK.
• Australia:
  • You need a certificate of no impediment (CNI) issued in Thailand by the Embassy in Bangkok or the Consulate-General in Phuket. Thai authorities don't accept a "Single Status Certificate" from an Australian Births, Deaths and Marriages office.
  • If you're both Australian, each of you applies separately. Fees apply.
  • Source: Australian Consulate-General Phuket, March 2026.

Any other nationality: ask your own embassy in Thailand.

Fees and timing

• Off-site registration: 200 baht if the registrar comes to you, plus their transport (DOPA guidebook).
• Embassy documents: US$50 (US) or £75 (UK). Australia says "fees apply" without listing them.
• Translation and MFA legalisation: extra. The US Embassy calls the MFA fee "nominal" but doesn't give a figure.
• Time: the whole process "can take several days" (U.S. Embassy). Plan on a few working days in Bangkok or Chiang Mai, where the legalisation offices are.

For scale, 200 baht is about US$6. That's based on the US Treasury reporting rate of 33.58 baht to the dollar on 30 Sep 2026 (US Treasury).

Legal at home, symbolic in Thailand: why most couples do this

The Australian Consulate says it plainly: "Some couples choose to complete their legal marriage in Australia, such as through a registry office, and then hold a separate informal ceremony and/or wedding reception with family and friends in Thailand" (source). It's simpler for a few reasons:

• No paperwork days: you don't lose working days in Bangkok to embassy and MFA appointments.
• No translations: nothing needs translating into Thai.
• Any date and place: your Thailand ceremony can happen wherever and whenever you like.

We see the same pattern in China and Bali.

What this means for Phuket, Koh Samui and Chiang Mai weddings

Your resort ceremony in Phuket, Koh Samui or Chiang Mai is the symbolic part. If you also want to be legally married in Thailand, it depends on where you are:

• Phuket: Australians can get their CNI at the Consulate-General there (source). The MFA legalisation offices are in Bangkok and Chiang Mai, so allow travel time.
• Chiang Mai: it has both a US Consulate and an MFA legalisation office (U.S. Embassy).
• Koh Samui: none of the official pages we used lists an embassy or legalisation office on the island. Plan for paperwork in Bangkok or Chiang Mai, where the MFA legalisation offices are.
• British couples, anywhere: your affirmation names the province you'll marry in, so pick it before you apply (GOV.UK).

FAQ

Can two foreigners get legally married in Thailand?
Yes. Two foreigners can register a marriage at any Thai district office (amphur or khet), as long as both are 18 or over (with parental consent if under 20), free to marry and bring two witnesses. Each of you needs your own embassy's document, translated into Thai and legalised by the Ministry of Foreign Affairs.

Is a Thai wedding ceremony legally binding?
No. A beach, temple or resort ceremony on its own is not a legal marriage. Under Thai law, a marriage is only valid once it is registered with the Thai authorities.

What documents do foreigners need to marry in Thailand?
Your passport; your embassy's certificate of no impediment, affirmation or affidavit of marital status; a Thai translation legalised by the Ministry of Foreign Affairs; proof that any earlier marriage has ended; and two witnesses. Each district office can ask for more, so check with yours first.

How much does it cost to register a marriage in Thailand?
Off-site registration costs 200 baht, plus the registrar's transport. Your own embassy charges separately: US$50 for the US affidavit, or £75 for the UK affirmation and certified passport copy. Translation and MFA legalisation cost extra.

How long does legal marriage take in Thailand?
The US Embassy says the process can take several days. The registration itself takes 20 to 30 minutes. British nationals should apply at least 7 days before their embassy appointment, and in peak periods the wait for an appointment can be up to 3 weeks.
