Published by Nitin Bhatt on August 20, 2025August 20, 2025

If you’re a foreign man planning to marry a Thai woman, registering your marriage in Thailand is a straightforward process. This guide provides a step-by-step overview to ensure your marriage is legally recognized.

1. Obtain an Affidavit of Freedom to Marry

The first step is to obtain an affidavit from your embassy confirming your current marital status (single, divorced, or widowed). Each embassy has its own procedures for issuing this affidavit. For example, U.S. citizens can complete a notarized affidavit at the U.S. Embassy in Bangkok.

2. Translate the Affidavit into Thai

The affidavit must be translated into Thai by a certified translator and then legalized by the Thai Ministry of Foreign Affairs (MFA). Translation agencies often provide combined translation and legalization services.

Translation Agencies Examples:

3. Submit Documents to the MFA for Legalization

Submit the following documents to the MFA for legalization:

Translated affidavit
Copy of your passport
Completed application form

Legalization usually takes 2–3 working days. Agencies can provide express service and courier support. Service charges for translation + legalization typically range from THB 1,500–2,000, including government processing fees.

4. Register the Marriage at the Amphur (District Office)

For the foreign man:

Passport + arrival card
Legalized translated affidavit (original + copy)

For the Thai woman:

Thai ID card / citizenship card
House registration
Written parental consent if under 20 (with certified Thai translation if needed)

Additional documents if previously married:

Divorce certificate, death certificate of prior spouse, or court decree (translated if not in Thai)

Two witnesses are required if parents are unavailable. The Amphur provides two marriage certificates: one showing the woman’s original surname and one for the foreign man. Certificates are in Thai.

5. Optional: Translation and Legalization of Marriage Certificate

If you plan to use your marriage certificate outside Thailand, it’s advisable to have it translated into English and legalized by the MFA. This ensures the document is recognized internationally.
