Marriage Registration at the Thai Amphur: Complete Step-by-Step Guide (2026)

TL;DR

Civil marriage in Thailand is administered by the Amphur (ที่ว่าการอำเภอ / district office) under Civil and Commercial Code B.E. 2468 (1925) (CCC) Sections 1448-1467 and, since 22 January 2025, the Marriage Equality Act B.E. 2567 (2025) (พระราชบัญญัติแก้ไขเพิ่มเติมประมวลกฎหมายแพ่งและพาณิชย์ พ.ศ. 2567) — which opens marriage to same-sex couples. Foreign nationals must obtain an Affirmation of Freedom to Marry from their embassy, have it translated into Thai, legalise the translation at MFA Chaengwattana, and present it at the Amphur. Registration is same-day with two witnesses. Prenuptial agreements must be registered the same day at the Amphur (CCC Section 1465).

Legal Framework

Marriage in Thailand is governed by:

• Civil and Commercial Code Sections 1448-1467 — conditions, registration, voidability, and effect.
• Marriage Equality Act B.E. 2567 (2025) — in force 22 January 2025; replaces gendered "man" / "woman" language in the CCC with "two persons" (สองบุคคล), opening civil marriage to same-sex couples on equal terms.
• Registration of Family Act B.E. 2478 (1935) as amended — administrative procedure.
• Civil Registration Act B.E. 2534 (1991) as amended — household registration interactions.

The only legally valid Thai marriage is the registered civil marriage at the Amphur. Religious ceremonies (Buddhist, Christian, Muslim, Hindu) have no civil legal effect on their own; they are commonly held alongside, but never instead of, Amphur registration.

Conditions and Capacity

Under CCC Sections 1448-1454, the parties must:

• Both be at least 18 years old (court permission required for 17+; under 17 strictly prohibited).
• Not be currently married to another person (no polygamy; bigamy invalidates the second marriage).
• Not be ascendants, descendants, or full/half siblings (Section 1450).
• Have legal capacity — persons of unsound mind or under guardianship require court approval (Section 1449).
• Have consented freely — duress voids the marriage (Section 1448).

A widow or divorcée must wait 310 days after the previous marriage ended before remarrying, unless: (a) a child has been born meanwhile, (b) the previous spouse is the same person, (c) a court has approved earlier remarriage, or (d) a medical certificate confirms non-pregnancy (Section 1453).

The Foreign-Foreign Marriage Path

Two foreigners can marry at a Thai Amphur — Thai law applies to the registration. Each party obtains an Affirmation from their respective embassy, translates and MFA-legalises it, and attends the Amphur. Where the two embassies are in different cities (or where one party's embassy is not in Thailand), allow 2-6 weeks lead time.

Same-sex foreign-foreign couples can now register since the Marriage Equality Act B.E. 2567 (2025) came into force on 22 January 2025. The Amphur uses the gender-neutral "two persons" forms; some districts have updated forms faster than others.

The Registration Day

1. Arrive at the chosen Amphur in the morning. Bangkok options include the larger district offices (Bang Rak, Watthana, Khlong Toei, Lat Phrao); Bang Rak (บางรัก) is famously popular on auspicious dates.
2. Submit documents to the family registrar (นายทะเบียน) — review takes 30-60 minutes.
3. Sign the marriage register (ทะเบียนสมรส) in the presence of two witnesses and the registrar.
4. The registrar prints the Marriage Certificate (Kor.Ror.3 / ใบสำคัญการสมรส) and the official Marriage Register entry (Kor.Ror.2 / ทะเบียนสมรส). Both spouses receive the original Marriage Certificate, and the Register is held by the Amphur.
5. If a prenuptial agreement is being used, present it the same day for entry on the back of the Register — see Section 1465.
6. Optional: request English-language certified extracts for use abroad.

Fees: registration is free; certified Thai-English copies cost THB 10-100 per page; an English translation booklet costs more if obtained via an outside translator.

Prenuptial Agreements (สัญญาก่อนสมรส)

Under CCC Section 1465, a prenuptial agreement must be: (a) in writing, (b) signed by both parties and two witnesses, and (c) registered with the marriage at the Amphur on the same day. A prenup signed before the wedding day but not entered on the Register is unenforceable. Standard contents include separation of premarital assets, treatment of gifts and inheritance during marriage, and division of property on divorce; clauses contrary to public order or good morals (e.g., parental-rights waivers) are void.

After Registration

Common Mistakes

Avoid these traps:

• Skipping the Affirmation step. The Amphur will not register a foreigner without an embassy Affirmation — bookings often need 3-10 days at the embassy.
• Affirmation not translated and MFA-legalised. The Thai translation must be MFA-stamped or the Amphur will refuse.
• Bringing a prenup but not registering it the same day. Section 1465 is unforgiving — late registration is void.
• Missing the 310-day rule. Previously married parties need death/divorce documents to override the rule — bring them.
• Assuming a religious ceremony is enough. Without Amphur registration there is no civil marriage; assets, inheritance, and visa rights do not arise.
• Wrong Amphur jurisdiction. You can register at any Amphur in Thailand; choose by convenience, but be aware some Amphurs decline foreign-only marriages without local-resident documentation.

FAQs

1. Can two foreigners marry in Thailand?

Yes. Each foreign party needs an embassy Affirmation, translated and MFA-legalised, then attends the Amphur with two witnesses. Same-sex foreign-foreign couples can now do this under the Marriage Equality Act B.E. 2567 (2025).

2. How long does the Affirmation chain take?

Plan 1-3 weeks: 3-10 days at the embassy, 1-3 days for translation, 1-3 days at MFA Chaengwattana.

3. Does Thailand recognise foreign same-sex marriages?

From 22 January 2025, the Marriage Equality Act treats foreign same-sex marriages on the same footing as opposite-sex marriages for Thai civil purposes — see our Marriage Equality coverage.

4. Can we marry the same day we collect the Affirmation?

Yes, technically. In practice, allow the embassy-to-Amphur logistics: translator and MFA take 1-3 days. Book the embassy slot first, then schedule.

5. Is a Thai marriage valid in my home country?

Most countries recognise it once the certificate is MFA-legalised and destination-embassy authenticated. The 1961 Apostille Convention is unavailable; use the consular chain — see MFA legalisation guide.
