Thai Marriage Registration Service

In Thailand, a marriage is only legally recognized once it is officially registered at a local district office (Amphur or Khet). Religious or traditional ceremonies are symbolic and do not carry legal weight until this registration is complete. 

As of January 2026, same-sex marriage is legal and follows the same registration procedures as opposite-sex marriage. 

1. Eligibility Requirements

  • Age: Both parties must be at least 18 years old (increased from 17 as of 2025; court approval is required if younger).
  • Status: Both must be single and free to marry.
  • Relationship: Must not be direct blood relatives or share the same adoptive parents.
  • Waiting Period: A woman whose previous marriage ended within the last 310 days must provide a medical certificate of non-pregnancy or a court order to remarry. 

2. Required Documents

Requirements vary based on nationality: 

For Thai CitizensFor Foreign Nationals
Thai National ID CardValid Passport and Thai Visa/Arrival Card
House Registration (Tabien Baan)Affirmation of Freedom to Marry (from your embassy in Thailand)
Proof of divorce or death of prior spouse (if applicable)Certified Thai translation of the Affirmation
Name change certificate (if applicable)Proof of divorce/death of prior spouse (translated and certified)

3. Step-by-Step Process

  1. Embassy Clearance: Foreigners must visit their respective embassy in Thailand to obtain an “Affirmation of Freedom to Marry”.
  2. Translation: Translate the embassy affirmation (and any foreign divorce/death certificates) into Thai through a certified service.
  3. Legalization: Submit the translated documents to the Thai Ministry of Foreign Affairs (MFA) in Bangkok for legalization. This typically takes 2–3 business days.
  4. Registration at Amphur: Both parties must appear in person at any District Office (Amphur or Khet) with all original and legalized documents. You must bring two witnesses (over age 20) with valid IDs.
  5. Certification: Upon completion, you will receive two copies of the official Thai Marriage Certificate. 

4. Important Considerations

  • Fees: Official registration at the district office is free or incurs a nominal fee (approx. 20–100 THB), though external services like legalization and translation will have higher costs.
  • Prenuptial Agreements: Must be drafted in Thai (or bilingual) and submitted at the time of registration; they cannot be added to the register later.
  • Marriage Visa: Foreigners married to Thai citizens may apply for a Non-Immigrant O (Marriage) Visa, allowing long-term stay and the ability to apply for a work permit.
  • International Recognition: To use your Thai marriage certificate abroad, have it translated into your native language and legalized again by the Thai MFA and your own embassy.
