Thailand legalized same-sex marriage on January 22, 2025. The Marriage Equality Act passed parliament in June 2024, received royal assent in September 2024, and came into effect the following January. Thailand became the first Southeast Asian country to recognize same-sex marriage with full legal equality including inheritance, medical decision-making, joint property, and adoption rights.
This guide is the practical legal and logistical walkthrough for couples planning to marry in Chiang Mai: legal requirements, documents needed, the district office (amphoe) filing process, costs, witness requirements, and international recognition. For wedding-planning specifics (venues, ceremonies, photography), see the venue section at the bottom and our broader LGBT context guides.
The legal framework
The Marriage Equality Act amends Thailand's Civil and Commercial Code to make marriage gender-neutral. Key provisions:
- Same-sex couples have identical legal rights to opposite-sex couples.
- Inheritance, joint property, medical decision-making, hospital visitation rights are equal.
- Adoption rights are equal (with the usual adoption-process requirements).
- Tax benefits, immigration sponsorship for spouses, and other marriage-related legal privileges apply equally.
- Marriage can be performed at any district office (amphoe).
- Both Thai and foreign couples can marry, including mixed Thai-foreign same-sex couples.
Who can marry
- Two Thai citizens: Standard. File at any amphoe.
- One Thai and one foreigner: Standard. Foreign partner needs single-status affidavit from home country embassy plus translation.
- Two foreign citizens: Yes, can marry in Thailand. Both partners need single-status affidavits.
- Same-sex couples from countries where same-sex marriage is illegal: Yes, can marry in Thailand. Recognition in home country depends on home-country law; consult before deciding.
The amphoe (district office) filing
What is an amphoe?
An amphoe is a district administrative office. Thailand has hundreds. Marriages are registered at any amphoe; you don't need to use the one corresponding to your residence. Chiang Mai has multiple amphoe options:
- Mueang Chiang Mai amphoe: central district office, most accessible from Old City and Nimman.
- San Sai amphoe: northeast district.
- Hang Dong amphoe: southern district.
- Other suburban amphoe: Saraphi, San Kamphaeng, Mae Rim, others.
What happens at the filing
- Both spouses arrive at the amphoe with all documents and two witnesses.
- Documents are reviewed by the amphoe officer.
- Both spouses sign the marriage register in Thai.
- Witnesses sign.
- The amphoe officer issues the marriage certificate (in Thai) on the same day.
- You can request English translations from the amphoe or get them certified afterward.
The actual filing takes 1 to 3 hours including waiting. Some amphoe offices are more experienced with foreign marriages than others; if you're a foreign couple, calling ahead to confirm same-sex foreign marriage filing experience is worth doing.
Documents required
For Thai spouses
- Thai national ID card
- House registration document (tabian baan)
- If divorced or widowed: documentation of previous marriage ending
For foreign spouses
- Valid passport (6+ months remaining validity)
- Single Status Affidavit from your home-country embassy in Bangkok or Chiang Mai consulate (where applicable). Declares you're legally free to marry. Cost typically $50 to $200 depending on country. Allow 1 to 4 weeks.
- Translation into Thai of the affidavit. Done by a certified translator in Thailand. Cost ฿1,500 to ฿3,500.
- Authentication or apostille: The translated affidavit may need to be authenticated by the Thai Ministry of Foreign Affairs (MFA Department of Consular Affairs in Bangkok). Cost ฿200 to ฿400. Allow 1 to 2 weeks. Some amphoe accept embassy-issued affidavits directly; others require the MFA step. Confirm with your chosen amphoe.
- Marriage application form (provided by the amphoe).
- If divorced or widowed: documentation of previous marriage ending, translated and authenticated.
Witnesses
Two witnesses required. They must:
- Be 20 years of age or older
- Have valid ID (passport for foreigners, Thai ID for Thai citizens)
- Be present at the filing
Witnesses don't need to be related, know the couple personally, or be Thai. You can bring friends, family, hire local witnesses through wedding planners (฿1,000 to ฿3,000 per witness service), or in some cases the amphoe can arrange local witnesses for a small fee.

| Item | Approximate cost |
|---|---|
| Amphoe filing fee | ฿100 to ฿500 |
| Single status affidavit (per foreign spouse) | $50 to $200 |

| Typical total legal cost | ฿15,000 to ฿35,000 ($425 to $1,000) |
Costs above are for legal filing only. A full wedding celebration (ceremony, venue, photography, reception, attire) varies enormously: ฿100,000 to ฿1,000,000+ depending on scale and style.
Step-by-step timeline
- 4 to 8 weeks before: Request single status affidavit from your home country embassy. Each embassy has its own process and timeline.
- 2 to 4 weeks before: Receive affidavit. Take it to a certified translator in Thailand for Thai translation.
- 1 to 2 weeks before: If MFA authentication is needed, submit translated affidavit to MFA in Bangkok. Receive authenticated document.
- 3 to 7 days before: Confirm appointment with chosen amphoe. Arrange witnesses.
- Wedding day: Both spouses + witnesses + documents at the amphoe. Filing takes 1 to 3 hours. Receive Thai marriage certificate.
- Same day or after: Request certified English translation of marriage certificate from the amphoe or a separate translator. Useful for home-country recognition.
International recognition
Whether a Thai-issued same-sex marriage is recognized in your home country depends on home-country law.
Countries that typically recognize Thai same-sex marriages
- Most EU member states
- United Kingdom
- United States
- Canada
- Australia
- New Zealand
- Most South American countries that recognize same-sex marriage
For these countries, the typical process is: take your Thai marriage certificate (translated and authenticated) to your home-country embassy or, on return home, to your local marriage records office. Some countries require additional registration steps.
Countries that may not recognize Thai same-sex marriages
- Countries where same-sex marriage is illegal
- Some countries with civil partnership frameworks may recognize Thai marriage as civil partnership rather than marriage
- Various jurisdictions have specific requirements or limitations
Always consult a family lawyer in your home country before relying on Thai marriage for legal purposes (immigration, inheritance, taxation). For couples from countries where same-sex marriage is illegal, Thai marriage may still provide legal rights within Thailand and in third countries that recognize same-sex marriage, but may have limited home-country effect.
Wedding venues in Chiang Mai
Beyond the legal filing, couples often want a ceremony or celebration. Chiang Mai offers many options:
Hotel and resort weddings
- Major international hotels (Anantara, Le Meridien, Shangri-La) host LGBT weddings.
- Smaller boutique hotels in Mae Rim and Hang Dong offer destination wedding packages.
- Riverside venues along the Ping River.
Temple blessings
Some Thai Buddhist temples offer LGBT-affirming blessings. The Buddhist tradition is generally accepting; individual temples and monks vary. Wedding planners with experience in LGBT ceremonies can recommend specific options.
Outdoor and nature ceremonies
Mae Rim hill resorts, gardens, waterfall venues, and traditional Lanna-style outdoor settings. Increasingly popular for destination weddings.
Private villa weddings
Hang Dong and Mae Rim villa rentals can host intimate ceremonies. Cost varies enormously based on villa quality and guest count.
LGBT-experienced wedding planners
Multiple Chiang Mai-based planners specialize in or have substantial experience with LGBT weddings. Costs range ฿80,000 to ฿500,000+ depending on scope. Worth using a planner if you're a foreign couple unfamiliar with Thai wedding logistics.
Common questions
Do we need a Thai residence to marry here?
No. Foreign tourists on standard tourist visa can marry in Thailand. No residency requirement.
How quickly can we marry after arriving in Thailand?
If all documents are prepared in advance (single status affidavits already authenticated), as quickly as 1 to 3 business days after arrival. If preparing documents in Thailand, allow 2 to 6 weeks.
Can we apply at the amphoe online?
The filing itself must be in person. Some preparatory steps can be coordinated remotely. Wedding planners can handle most preparation on your behalf.
What if one of us doesn't speak Thai?
The amphoe officer signs and witnesses the marriage in Thai. You can bring a Thai-speaking friend or hire an interpreter (฿1,000 to ฿3,000 for the filing). Some amphoe officers speak some English; others don't.
Can we change our names after marriage?
Name change procedures vary by your home country. Thai marriage certificates don't automatically change your legal name in your home country; you'll need to follow your home-country name-change process.
