Marriage Registration in Thailand

Registering a marriage in Thailand is more than just a romantic gesture; it is a rigorous administrative process that transforms a union into a legal entity recognized worldwide. Whether you are a local couple or a foreign national, navigating the "Land of Smiles'" bureaucracy requires careful planning, specific documentation, and a clear understanding of the Thai Civil and Commercial Code.

As of 2026, Thailand has also made historic strides in inclusivity, becoming the first Southeast Asian nation to implement Marriage Equality, allowing couples of any gender to register their union with the same legal rights as traditional marriages.

1. Eligibility: Who Can Marry in Thailand?

Before gathering paperwork, couples must ensure they meet the fundamental legal requirements set by the Department of Provincial Administration:

  • Age: Both parties must be at least 17 years old. If either party is under 20, written parental consent is mandatory.

  • Marital Status: Both must be single or legally divorced. Thailand strictly prohibits bigamy; a person cannot be registered as married to more than one person simultaneously.

  • The 310-Day Rule: For women whose previous marriage ended (via death or divorce), a waiting period of 310 days is required before remarrying. This can be waived if a medical certificate proves the woman is not pregnant, if she is remarrying the same spouse, or if a child was born during that period.

  • Consanguinity: The parties must not be direct blood relatives (parents, siblings, etc.) or share the same adoptive parents.

2. The Paperwork: A Tale of Two Tracks

The documentation required differs significantly depending on your citizenship.

For Thai Nationals

Thai citizens face a simpler route, requiring:

  • Thai National ID Card.

  • House Registration Book (Tabian Baan).

  • Proof of Termination of Previous Marriage (if applicable), such as a Divorce Certificate or Death Certificate.

For Foreign Nationals

Foreigners must complete a "pre-registration" phase to prove they are legally free to marry. This is the most time-consuming part of the process.

  1. Affirmation of Freedom to Marry: This is a sworn affidavit obtained from your country's embassy in Bangkok. It confirms your identity, occupation, income, and status as a single person.

  2. Passport Certification: A notarized copy of your passport biodata page, also provided by your embassy.

  3. Legalized Translations: Once you have the embassy documents (usually in English), they must be translated into Thai by a certified translation bureau.

  4. MFA Authentication: The translated documents must then be legalized by the Ministry of Foreign Affairs (MFA) in Bangkok (located at Chaeng Wattana or specific MRT stations like Khlong Toei). The MFA verifies the consular official's signature, a process that typically takes 2–3 business days.

3. The Registration Process at the "Amphur"

Once the documents are legalized, the actual marriage takes place at a local district office, known as an Amphur (or Khet in Bangkok).

Step-by-Step Procedure:

  1. Choosing the Venue: You can register at any Amphur in Thailand; you are not restricted to your place of residence. Popular choices include Bang Rak (the "Village of Love") due to its auspicious name.

  2. The Witnesses: You must bring two witnesses. While some offices allow staff to act as witnesses for a small fee, it is safer to bring your own, especially if an interpreter is needed.

  3. The Interview: The registrar will briefly interview the couple to ensure the marriage is voluntary. If either party does not speak fluent Thai, a qualified interpreter (not the spouse) must be present.

  4. Signing the Register: Both parties sign the Marriage Register.

  5. Issuance of Certificates: You will receive two documents:

    • Khor Ror 2: The Marriage Register (a detailed administrative record).

    • Khor Ror 3: The formal Marriage Certificate (the ornate, flowery document).

Note: A religious or traditional Buddhist ceremony carries significant cultural weight but has no legal standing in Thailand. Only the registration at the Amphur makes the marriage official.

4. Legal Implications: Property and Assets

Thai law distinguishes between property owned before and after marriage, which is vital for long-term financial security.

Property TypeDefinition (Thai Law)Management
Sin Suan TuaPersonal property owned before marriage, or gifts/inheritances received during marriage.Managed solely by the individual owner.
Sin SomrosMarital property acquired during the marriage (wages, interest, purchased assets).Requires joint consent for major actions (selling land, mortgages).

The Role of Prenuptial Agreements

In Thailand, a prenuptial agreement must be registered at the same time as the marriage. It cannot be added later. If you wish to keep certain assets separate or define specific management rights, the agreement must be in writing, signed by both parties and two witnesses, and attached to the marriage register at the Amphur.

5. Post-Registration: Global Recognition

To ensure your Thai marriage is recognized in your home country, you should:

  1. Translate the Thai Marriage Certificate (Khor Ror 3) and Register (Khor Ror 2) into English.

  2. Have these translations legalized by the Thai MFA.

  3. Report the marriage to your home country’s embassy if required (e.g., for visa or inheritance purposes).

Success Tips for 2026:

  • Queueing: Many Amphurs now allow online queue reservations via the "BORA" website to avoid long wait times.

  • Timing: Allow at least one full week in Bangkok if you are a foreigner to handle the embassy, translation, and MFA steps before heading to the Amphur.

  • Fees: While the registration itself is nearly free (approx. 20–50 Baht), embassy affidavits and MFA legalization can cost between $100 and $300 total.
