Overview of Marriage Registration

Marriage registration in Thailand is a civil procedure conducted at a District Office (Amphur or Khet in Bangkok). For a marriage to be legally recognized in Thailand, it must be registered with the civil authorities. Religious or traditional ceremonies alone do not create a legal marriage.

When one or both parties are foreign nationals, additional documentation is required to prove identity, legal capacity to marry, and that no legal impediments exist.

Same-Sex Marriage: As of January 22, 2025, Thailand recognizes same-sex marriage under the Marriage Equality Act. The registration process and document requirements are the same for all couples regardless of gender.

Legal Requirements to Marry in Thailand

The Marriage Registration Process

Registering a marriage involving a foreigner in Thailand typically involves multiple steps and several government offices. Allow adequate time to complete the process.

1

Obtain Affidavit of Freedom to Marry

Visit your country's embassy or consulate in Thailand to obtain an affirmation or affidavit stating you are legally free to marry. This document confirms you are single, divorced, or widowed and have no legal impediments to marriage.

  • Schedule an appointment with your embassy (often required)
  • Bring your passport, any previous marriage/divorce documents
  • Swear an oath before a consular officer
  • Pay the embassy fee (varies by country)
2

Translate Documents into Thai

All foreign documents must be translated into Thai by a certified translator. This includes the affidavit, passport data page, and any divorce or death certificates from previous marriages.

  • Use a translator certified by the Thai Ministry of Foreign Affairs
  • Keep original documents and translations together
  • Translation cost: approximately 300-500 THB per page
3

Legalize at Ministry of Foreign Affairs

Take the translated documents to the Thai Ministry of Foreign Affairs (MFA) Legalization Division for certification. This authenticates both the original foreign documents and their Thai translations.

  • MFA Legalization Office: Chaengwattana Government Complex, Building B
  • Processing: Same day if submitted early, or next business day
  • Fee: 400 THB per document
  • Operating hours: 8:30 AM - 3:30 PM, Monday-Friday

After Registration: Marriage Certificate

Upon successful registration, you will receive a Thai marriage certificate called "Kor Ror 3" (or in Thai script). This is your official proof of marriage in Thailand.

What to Do with Your Certificate

Registration in Home Country

Many countries require or recommend registering foreign marriages with your home country's authorities. This typically involves:

Visa Implications: A registered Thai marriage is the prerequisite for applying for a marriage visa extension. See our Marriage Visa Extension Guide for details on financial requirements and the immigration process.

Common Issues and Solutions

Previous Marriage Not Properly Dissolved

If you were previously married, you must prove that marriage has legally ended. This requires either a divorce decree or death certificate of your former spouse, properly certified and translated.

Name Discrepancies

Ensure all documents show consistent name spelling. Discrepancies between passport, affidavit, and other documents can cause delays or rejection. If you have legally changed your name, bring proof of the change.

Embassy Does Not Issue Affidavits

Some smaller embassies may not have the capacity to issue affidavits. In such cases, you may need to contact the nearest embassy that does, or obtain documentation from your home country directly.

Language Barriers at Amphur

Staff at District Offices may not speak English fluently. Bringing a Thai-speaking friend, your Thai partner, or a professional translator can help ensure smooth communication.

Document Validity Periods

Some documents have expiration dates. Embassy affidavits are typically valid for 3-6 months. If you experience delays, you may need to obtain fresh documentation.

Prenuptial Agreements

Thailand recognizes prenuptial agreements (sometimes called antenuptial agreements) that are registered at the same time as the marriage. These can specify how property will be divided in case of divorce.

Requirements for Valid Prenup

Cannot Be Added Later: Under Thai law, a prenuptial agreement must be registered at the time of marriage. You cannot create or register a prenup after the marriage is already registered.

Frequently Asked Questions

Can I marry on a tourist visa?

Yes, you can legally register a marriage in Thailand while on a tourist visa. However, to subsequently obtain a marriage visa extension, you will need to apply for or convert to a Non-Immigrant O visa.

Which Amphur should I go to?

You can register at any District Office in Thailand. Many couples choose one convenient to their location. Some offices are more experienced with foreign marriages than others.

Do we need an interpreter at the Amphur?

There is no legal requirement for an interpreter, but if neither of you speaks Thai, having someone who can communicate with staff is highly recommended.

How quickly can we complete the process?

With all documents prepared in advance and good timing, the entire process can be completed in about one week. Rushing increases the risk of errors or omissions.

Is our Thai marriage recognized in my home country?

Most countries recognize marriages legally performed abroad. However, you may need to register the marriage or provide proof of validity. Check with your home country's authorities.
