Getting married in Thailand as a foreigner is a paperwork exercise more than a ceremony. The marriage becomes legal only when it is registered at a Thai district office, and to register you need a signed statement from your embassy in Thailand that you are free to marry, a Thai translation of that statement, and authentication of both by Thailand’s Ministry of Foreign Affairs. Once those documents are in hand, both spouses appear in person at a district office with two witnesses, sign the register, and receive the marriage certificate. A wedding ceremony, religious or otherwise, is not part of the legal process and carries no weight on its own.
The Four Steps, Start to Finish
The process runs in a fixed order because each step depends on the one before it:
- Get a “freedom to marry” affidavit from your embassy or consulate in Thailand.
- Have the affidavit translated into Thai by a certified translator.
- Take the original and the translation to the Department of Consular Affairs at the Ministry of Foreign Affairs to be legalized.
- Both spouses go to a district office with the legalized documents, valid ID, and two witnesses to register the marriage.
Plan on at least a week on the ground, more if your embassy has appointment backlogs or if you want standard rather than expedited MFA processing.
Step 1: The Embassy Affidavit
Your home country’s embassy or consulate in Thailand issues a document confirming you are legally single and eligible to marry. The U.S. Embassy in Bangkok calls it a “notarized marriage/divorce affidavit” and requires the American citizen to appear in person with a valid passport. If you were previously married, bring the original divorce decree or death certificate, not a copy.1U.S. Embassy & Consulate in Thailand. Getting Married in Thailand
Other countries use different names for the same document. The Greek Embassy issues a “certificate of freedom to marry.” The purpose is identical: proving to the Thai registrar that your own country considers you eligible to marry. Contact your embassy before your trip to confirm current fees, appointment lead times, and required supporting documents.
Step 2: Translation and MFA Legalization
Thai district offices do not accept foreign-language documents. Your embassy affidavit needs a certified Thai translation, and both the original and the translation must then be legalized by the Department of Consular Affairs at Thailand’s Ministry of Foreign Affairs.1U.S. Embassy & Consulate in Thailand. Getting Married in Thailand Legalization is the MFA verifying that the signatures and stamps on your documents are authentic. Without that authentication, the district office will turn you away.
Standard MFA processing takes a few business days. Because this step sits between the embassy visit and the district office appointment, it usually sets the pace of the whole trip.
Step 3: Registering at the District Office
With the legalized documents ready, both spouses go to a local district office to register. In the provinces this is called an amphur; in Bangkok it is called a khet. Both parties must appear in person, and you need two witnesses who bring valid identification, either Thai ID cards or passports. Some district offices can supply staff members as witnesses for a small fee if you have not brought your own.
The registrar reviews your documents, confirms eligibility under the Civil and Commercial Code, enters your details into the national marriage register, and issues the marriage certificate, known as the Kor Ror 3. The marriage is legally effective from the moment of registration. No ceremony is required for it to be valid, and no ceremony makes it valid without this step.
Who Is Eligible to Marry
A few rules can stop a foreigner from registering, so check them before you travel:
- Both parties must be at least 18. Anyone under 20 also needs parental or guardian consent, since 20 is the age of full legal majority in Thailand. Consent can be given by signing the register in person, by a signed written statement, or verbally in front of at least two witnesses.
- Neither party can already be legally married. Bigamy is prohibited under Section 1452 of the Civil and Commercial Code, and a bigamous marriage is void from the start, not merely voidable. It is also a criminal offense under the Thai Penal Code.
- A woman whose previous marriage ended by divorce or her spouse’s death must wait 310 days before remarrying. The rule can be waived if a child has already been born during that period, if she is remarrying the same person, if a doctor certifies she is not pregnant, or if a court permits the marriage.
Since January 23, 2025, Thailand’s Marriage Equality Act has opened registration to all couples regardless of gender. Same-sex couples use the same district offices, the same documents, and receive the same Kor Ror 3 certificate, and Thai law treats the marriage identically for inheritance, adoption, medical decisions, and property.2United Nations in Thailand.

Prenuptial Agreements and Marital Property
Foreign spouses are often surprised by Thailand’s default property rules. Anything you owned before marriage stays personal property (sin suan tua), along with personal-use items, tools of your trade, individual gifts, and inheritances not declared as marital assets. Everything else acquired during the marriage is marital property (sin somros) and is owned jointly. Income earned from personal property during the marriage also becomes marital property, so the rent from a pre-owned apartment is shared even though the apartment is not. Major transactions in marital property, including sales of real estate, leases longer than three years, and loans, require both spouses’ consent.
A prenuptial agreement can override these defaults, but Thai law leaves no room for informality. The agreement must be in writing, signed by both spouses and at least two witnesses, and recorded in or attached to the marriage register at the moment of registration. Miss any of those requirements and the prenup is void. It cannot be created or added after the wedding day. Draft, review, and finalize it before you walk into the district office, then hand it to the registrar with your other documents. Any later change requires a court order, and couples with assets abroad should know that a Thai prenup is governed by Thai law and may not be automatically enforced in another country.
Getting the Marriage Recognized in Your Home Country
The Kor Ror 3 is a legal document inside Thailand, but your home country will not automatically know the marriage exists. Have the certificate translated into English or your country’s official language, then take it back to the MFA for the same legalization process you used for the affidavit.1U.S. Embassy & Consulate in Thailand. Getting Married in Thailand With the legalized translation, visit your embassy or consulate to have the marriage recorded in your home country’s system. Visa applications, inheritance, tax filing status, and social benefits at home all depend on your own government having a record of the marriage.
A Note for U.S. Citizens Planning a Spouse Visa
If you are an American citizen marrying a Thai national with the goal of bringing your spouse to the United States, be aware that as of January 2026 the U.S. Department of State paused immigrant visa issuances to nationals of certain countries, including Thailand, whose immigrants were identified as having a high rate of collecting public assistance. Thai nationals can still submit applications and attend interviews at the U.S. Embassy, and consular appointments continue to be scheduled, but actual visa issuance is on hold.3U.S. Embassy & Consulate in Thailand.

Check the embassy’s website for updates before committing to travel or relocation plans.
