Legal background — what the Marriage Equality Act actually changed
The Act Amending the Civil and Commercial Code (No. 24) B.E. 2567, commonly known as the Marriage Equality Act, was published in the Royal Gazette on 24 September 2024 and entered into force 120 days later on 23 January 2025. The amendment replaced gendered terms ("man" and "woman", "husband" and "wife") with gender-neutral terms ("persons", "spouses") in Sections 1448 through 1755 of the Civil and Commercial Code.
Practical effect: any two adults aged 18 or above, regardless of gender or nationality, can register a marriage at any district office in Thailand. The procedure, fees, and required documents are identical to those for opposite-sex marriages — there is no separate "civil union" or "partnership" category in Thai law.
Foreign couples and mixed-nationality couples (one Thai partner, one foreign partner; or both foreign) are explicitly included. Section 1448 as amended uses the term "persons" with no nationality restriction.
Required documents — foreign partner
Each foreign partner must produce the following at the district office on registration day:
- Original passport with a valid Thai entry stamp or visa
- Affirmation of freedom to marry (single-status certificate) issued by the partner's embassy in Bangkok — content must explicitly state the holder is free to marry and (in most cases) that the home country recognises same-sex marriage or has no objection
- Certified Thai translation of the affirmation, by an MFA-registered translator
- Legalization of the translation at the Department of Consular Affairs, MFA (THB 400 standard, THB 800 express)
- If previously married: divorce decree or death certificate of former spouse + Apostille (Hague member) or legalization (non-Hague) + certified Thai translation + MFA legalization
- Two Thai-speaking witnesses (NYC can arrange if needed)
Embassy single-status affirmations — what each major embassy issues
Embassies vary in how they issue the affirmation. Verified procedures, 2026:
- US Embassy Bangkok: notarised "Affidavit of Eligibility to Marry" — appointment via the consular booking system, fee USD 50
- UK Embassy Bangkok: "Affirmation/Affidavit of Marital Status" — appointment via the GOV.UK notarial services booking, fee GBP 50
- Australian Embassy: "Certificate of No Impediment to Marriage" — postal/in-person, fee AUD 233
- German Embassy: "Ehefähigkeitszeugnis" must be obtained from the German registry office (Standesamt) at home, then legalized at the German Embassy Bangkok
- French Embassy: "Certificat de Capacité à Mariage" — by appointment, mandatory pre-marriage interview
- Most other embassies (Canada, Netherlands, Spain, Sweden, etc.): issue a single-status statement on request — confirm with the embassy whether a same-sex-specific clause is required
Day-of registration — what to expect at the Amphoe
The marriage is recorded the same day at any Amphoe or, in Bangkok, any Khet office. The default procedure:
- Both partners attend in person with passports, the legalised single-status documents, and two witnesses
- Registrar reviews the documents (typically 30–60 minutes for foreign couples)
- Both spouses sign the Thai-language marriage register (Kor Ror 2) and receive the marriage certificate (Kor Ror 3)
- Government fee: THB 0 if performed during office hours at the office; THB 200 if registered outside the office (mobile registration)
- Couples may request an additional English-language extract — useful for embassy notification and overseas filings
After registration — making the marriage usable abroad
The Thai marriage certificate is in Thai. To use it overseas you typically need:
- Certified English translation of Kor Ror 2 / Kor Ror 3
- Apostille at MFA Bangkok (for use in any Hague member state including UK, US, Canada, Australia, Germany, France, the Netherlands, Spain, Brazil, etc.)
- OR Legalization chain (MFA + destination embassy) for non-Hague states such as the UAE, Saudi Arabia, Vietnam
- Filing with the home-country civil registry (Standesamt, état civil, GRO, Vital Statistics, etc.) — process varies by country
Recognition map — which countries currently recognize the marriage
As of June 2026, the home countries listed below recognize Thai same-sex marriages as full legal marriages on transcription:
- Full marriage recognition (38+ countries): US, UK, Canada, Australia, New Zealand, Germany, France, Spain, Netherlands, Belgium, Luxembourg, Ireland, Portugal, Sweden, Norway, Denmark, Finland, Iceland, Austria, Switzerland, Malta, Slovenia, Greece, Argentina, Brazil, Chile, Colombia, Ecuador, Mexico, Uruguay, South Africa, Taiwan, Nepal, Estonia, Andorra, Cuba
- Partial recognition or civil-union conversion: Italy, Czech Republic, Croatia, Hungary, Latvia, Liechtenstein, San Marino, Cyprus, Slovenia, Israel (foreign marriages only)
- No recognition (Thai marriage will not transfer): most Middle Eastern, Central Asian, North African and many ASEAN countries — confirm with the destination country's embassy in Bangkok before relying on the certificate abroad
Common scenarios and timelines
Scenario A — Both partners foreign, neither resident in Thailand: 5–7 working days from embassy appointment to district registration. Plan a 10-day Thailand trip.
Scenario B — One partner Thai, one foreign: 3–5 working days; the Thai partner only needs the national ID card and house registration (Tabian Baan).
Scenario C — Previously married partner: add 5–10 working days for divorce-decree Apostille/legalization and Thai translation.
Scenario D — Same-day registration as a symbolic ceremony: many couples combine civil registration in the morning with a private ceremony in the afternoon at a temple, beach venue, or hotel — only the morning Amphoe step is legally binding.
Common pitfalls to avoid
- Booking embassy single-status appointments too late — US/UK slots in Bangkok often book 4–6 weeks out
- Skipping the MFA legalization step on the embassy affirmation — Amphoe will refuse the file
- Assuming the home country automatically recognizes the marriage without filing — most countries require a transcription step at home
- Using a non-registered translator for the affirmation — only MFA-registered translators' translations are accepted at the legalization counter
- Forgetting the previous-marriage paperwork — every divorce/death of a prior spouse must be documented end-to-end
