Can Foreigners Register a Marriage in Thailand?

Many people may wonder whether foreigners are able to register a marriage in Thailand. The answer is yes — it is entirely legal, whether the marriage is between a foreigner and a Thai national, or between two foreigners.

However, the most important step in “marriage registration in Thailand for foreigners” is ensuring that all required documents from each person’s home country are fully prepared, as the specific documents, procedures, and processing times may vary depending on nationality.

Essential Documents to Prepare in Your Home Country for Marriage Registration in Thailand as a Foreigner

Before traveling to Thailand to register a marriage, foreigners are required to prepare all necessary documents in accordance with the requirements of the Thai District Office and their own country’s embassy or consulate.

1. Passport

A passport is an essential travel document that everyone must carry when traveling to any country, as it contains complete personal information including full name, photograph, place of residence, national ID number, gender, and date of birth. The following steps should be followed when preparing this document:

• Use the original passport in good condition, with no damage or defects
• Make copies of all pages containing entry/exit stamps and the most recent visa page
• The foreigner must personally sign each copy to certify it as a true copy
• The passport should have a remaining validity of no less than 6 months before entering Thailand

2. Certificate of Freedom to Marry

A Certificate of Freedom to Marry is a legal document issued by one’s home country as official proof that the individual is currently unmarried and free from any marital obligations — whether single, divorced, or widowed. It provides assurance to the prospective spouse that the marriage is legally valid and that no bigamy is taking place, in accordance with the law. This document has a validity period of only 3 to 6 months from the date of issue.

• A government agency in the applicant’s home country
• The applicant’s own country’s embassy in Thailand

Certificate of Freedom to Marry	Certificate of Freedom to Marry	Country of Use
Affidavit of Eligibility to Marry	Affidavit of Single Status Sworn Before a Consular Officer	United States of America (USA), Canada, United Kingdom (UK), Australia
Certificate of No Impediment (CNI)	Certificate of No Impediment to Marriage	United Kingdom (UK), Australia, New Zealand, Singapore, Italy
Certificate of No Marriage Record / CENOMAR	Certificate Confirming No Record of Marriage Registration Found in the Central Database	Philippines (known as CENOMAR, mandatory request from the PSA), Hong Kong
Certificate of Legal Capacity to Contract Marriage	Certificate of Eligibility to Marry Under the Law	Japan, Germany, Switzerland

3. Divorce Certificate

If a foreigner has previously been married and the divorce has been finalized, a Divorce Certificate must be presented as supporting evidence, along with a certified Thai translation of the document.

• The document must be authenticated by the authorities in the applicant’s home country, or certified for authenticity by the applicant’s own country’s embassy in Thailand before use
• The original certified document, along with its certified Thai translation, must be legalized through the Consular Affairs Department, Ministry of Foreign Affairs of Thailand, in order for it to be accepted by the District Office
• Under Section 1453 of the Civil and Commercial Code, if it is the woman who has divorced, remarriage may only take place once at least 310 days have elapsed since the dissolution of the previous marriage — unless she has already given birth, holds a medical certificate confirming she is not pregnant, or has obtained a court order permitting the marriage

4. Death Certificate of Former Spouse

If a foreigner’s previous spouse has passed away, the surviving spouse’s marital status automatically changes to widowed. In such a case, this document must be submitted as supporting evidence when proceeding with a new marriage. It must be translated into Thai and certified in the same manner as the Divorce Certificate, and must clearly state the full date — day, month, and year — of the former spouse’s death.

5. Birth Certificate

A Birth Certificate contains personal details such as name, address, place of birth, and parents’ names. While it may not always be required, certain District Offices or embassies specify that this document must be provided, as some countries’ passports do not include the passport holder’s parents’ names. However, the Thai marriage registration form contains fields requiring the full names of both parties’ parents, making accurate information necessary. Additionally, the legal systems of some countries may require a Birth Certificate to be verified before a Certificate of Freedom to Marry can be issued.

Do Documents for Marriage Registration in Thailand Need to Be Translated into Thai for Foreigners?

All documents issued by the authorities of the applicant’s home country must be translated into Thai in their entirety, as documents in English alone cannot be submitted. This is because the documents directly affect civil registration records, and therefore all translations must be completed before submission.

• Document translation must cover every single character without exception, including agency seals, the names of signing officers, and any notes or remarks. Nothing may be omitted, as any missing element will result in the document being rejected immediately.
• Names and surnames must be spelled consistently across all documents to prevent discrepancies or misidentification.
• Even after documents have been translated by a reputable translation center, the next step requires that both the original documents and their translations be submitted to the Nationality and Legalization Division, Consular Affairs Department, Ministry of Foreign Affairs of Thailand, for verification and official certification stamp — only then can the marriage be registered at the relevant District Office.

Documents	Translation	Certification	Note
1. Passport	❌	❌	Submit the original and provide photocopies
2. Certificate of Single Status	✅	✅	Required document
3. Divorce certificate	✅	✅	If there is
4. Death certificate	✅	✅	If there is
5. Birth certificate	✅	✅	Some District Offices require this to complete the parents’ names and surnames in the registration form

Document Legalization Process for Foreign Marriage Registration in Thailand at the Thai Consular Affairs Department

Before submitting documents for legalization, each document must be carefully reviewed to ensure that every character has been fully and accurately translated. Once all documents are in order, an online appointment must be booked in advance through the Consular Affairs Department’s system, as walk-in visits may result in no available queue slots and the service being refused immediately.

• The foreigner must travel in person to obtain a Certificate of Freedom to Marry from the relevant authority in their home country or their own country’s embassy in Thailand, and the document can be collected on the same day as the application (available within 1 working day).
• Once all documents have been obtained, they must be sent for Thai translation by a reputable translation institute or center. Every single character must be translated without exception — nothing may be skipped. Translation typically takes 2–3 days, or sooner for an additional express fee.
• Both the original documents and their translations must be submitted for legalization at the Consular Affairs Department, which takes approximately 3–5 working days. Officials will schedule a collection date or send the documents by post. Those who require express processing must submit before 10:00 a.m., subject to the daily quota, and an additional fee applies.
• Once all documents have been successfully certified and legalized, they can be submitted for marriage registration at the local District Office. Do not forget to bring witnesses to be present at the registration.

How Many Months in Advance Should Foreigners Prepare Their Marriage Registration Documents Before Flying to Thailand?

Foreigners planning to travel to Thailand for marriage registration should begin preparing their documents at least 1 to 3 months in advance. Preparing too far ahead may cause certain documents to expire sooner than expected. Having all documents fully prepared before departure will help ensure that the translation and legalization process proceeds more smoothly and efficiently.

• Before departing for Thailand, check the expiry date of your passport. If the passport has less than 6 months of remaining validity, it must be renewed in advance, as failure to do so will result in being denied entry into the country.
• It is advisable to begin the process of obtaining a Certificate of Freedom to Marry from your home country as early as possible. If this is not convenient, it can also be requested at your own country’s embassy in Thailand by making an appointment in advance for a faster service.
• Verify that all original documents are complete and in order.
• Once everything is ready, purchase a flight ticket to Thailand and proceed with the required steps upon arrival.

Which Countries Have Special Procedures for Foreign Marriage Registration in Thailand?

1. US Citizens

• An online appointment must be made in advance to visit the US Embassy on Wireless Road (Thanon Witthayu), Bangkok, or the US Consulate General in Chiang Mai.
• The required document is known as an “Affidavit of Eligibility to Marry.”
• The American national must personally fill in their own details (including parents’ names, financial status, and occupation), then appear before the consular officer to take an oath and sign the document in the officer’s presence.
• The US Embassy does not verify the applicant’s single status against databases in the United States. Instead, the applicant is personally sworn to take legal responsibility for the truthfulness of the declaration. Providing false information constitutes an offense of making a false statement and carries immediate legal consequences.

2. UK Citizens

• The British Embassy in Bangkok has officially discontinued the issuance of the CNI and replaced it with an Affirmation. UK nationals wishing to register a marriage in Thailand must download the Affirmation of Marital Status form from the United Kingdom government’s official website (GOV.UK) and complete it in advance.
• A Notarial Services appointment must be made at the British Embassy in Bangkok in order to sign and take an oath before a consular officer. The completed Affirmation must then be translated into Thai and submitted for legalization at the Thai Consular Affairs Department in the usual manner.

3. Australian Citizens

• The required document is known as a “Certificate of No Impediment (CNI).”
• Australian nationals can apply for a CNI through two channels: by applying in advance from Australia through the Smartraveller/DFAT agency, or by making an appointment to apply in person at the Australian Embassy in Bangkok.
• The Australian Embassy in Thailand conducts a thorough review of divorce records (if applicable). Importantly, a CNI issued by the Australian Embassy in Thailand is valid for only 3 months from the date of issue, so translation and marriage registration must be completed without delay.

4. European Citizens

• European countries such as France, Germany, Switzerland, Belgium, and others follow a procedure known as “Marriage Banns” — a formal advance announcement of the intended marriage.
• European nationals are typically required to submit documents from the Thai party (such as a birth certificate, house registration, and name change certificate, all translated into the relevant language) to the embassy in Thailand for review first.
• The embassy will then forward the matter to be publicly announced at the District Office in the foreigner’s home country for approximately 10–14 days, in order to determine whether anyone objects to the marriage.
• If no objections are raised, the home country will send an approval letter back to the embassy in Thailand, so that the embassy can issue a Certificate of Eligibility to Marry for the couple to have translated into Thai and proceed with registration.
• European nationals are therefore unable to fly to Thailand and register a marriage immediately, as the document preparation process takes approximately 1 to 3 months.

5. Chinese Citizens

• Chinese nationals from many regions cannot apply for a Certificate of Single Status directly at the Chinese Embassy in Thailand. In general, they must first obtain a certificate of single status from the civil registration office in their home province in China.
• A Double Certification process is required from China. The Chinese-language single status certificate must be notarized by a Chinese Notary Public, translated into English or Thai, and certified by China’s Ministry of Foreign Affairs (MFA) or the provincial foreign affairs office. It must also be endorsed by the Royal Thai Embassy in China before flying to Thailand.
• Upon arriving in Thailand with the fully certified documents from China, the applicant must then submit them to the Chinese Embassy in Thailand for an additional certification record, or have them translated into Thai and submitted to the Thai Consular Affairs Department for another round of legalization — a complex multi-layered certification process that requires a considerable amount of time.

How Many Days Does Marriage Registration in Thailand Take for Foreigners?

In general, marriage registration for both Thai nationals and foreigners can be completed at the District Office within 1 day, or approximately 1 to 2 hours per queue, depending on the number of people using the service on that day. For foreign marriage registration, if all documents are fully prepared, certified, and verified, and all procedures have been followed correctly, the couple can receive their marriage certificate and return home on the same day.

Is a Witness Required for Foreign Marriage Registration in Thailand?

Whether it is a marriage registration involving foreigners or Thai nationals, witnesses must be present to acknowledge the registration, as this is a legal requirement. At least 2 witnesses are required and must sign the marriage register in person before the registrar on the day of registration. For foreigners, an interpreter must also be brought along to serve as a witness.

• Witnesses must have reached the legal age of majority under Thai law, which is 20 years of age or older.
• They must be of full mental capacity and must not be a quasi-incompetent or incompetent person.
• An interpreter must be present for the foreign party to translate the content, rights, and legal obligations under Thai law upon completion of the marriage registration.
• The interpreter may also serve as a witness.
• Witnesses must prepare their national ID card along with a signed certified copy in advance.

What Can a Wedding Planner or Legal Service Help With?

Engaging the services of a Wedding Planner or a Legal Service company — a team of experts specializing in legal matters and marriage registration — will help ensure that the entire document preparation and registration process runs smoothly, without the couple having to navigate the procedures on their own. This provides peace of mind and confidence that everything will be handled successfully by professionals who offer comprehensive end-to-end support.

• Wedding Planner: Ideal for couples who want comprehensive assistance covering every aspect of their wedding, from conceptualizing the event, selecting a venue, and organizing the ceremony, to sourcing relevant vendors and coordinating all legal marriage documentation.
• Legal Service: Ideal for foreign couples who require a focus on legal accuracy, particularly in complex cases such as foreigners who have been divorced multiple times, those from European countries who are required to go through the Marriage Banns system, or those who wish to have a Prenuptial Agreement drawn up at the same time.

Pre-Flight Checklist Summary for Foreigners Registering a Marriage in Thailand

1. Prepare all required legal documents, including a passport, Certificate of Freedom to Marry, divorce certificate, death certificate, or birth certificate (if applicable), with both original copies and signed certified photocopies.

2. Make an online appointment in advance for foreigners who wish to obtain documents at their own country’s embassy in Thailand, for convenience and efficiency.

3. Contact a Thai translation center, and once the documents have been translated, book an online appointment in advance through the Thai Consular Affairs Department’s system to submit the translated documents for legalization.

4. Check your visa type and ensure you do not overstay beyond the legally permitted period, as overstaying a visa risks legal action and may prevent marriage registration from taking place.

5. Check that your passport has a remaining validity of no less than 6 to 12 months, as this affects travel arrangements — renewal should be completed well in advance.

6. Prepare a Prenuptial Agreement for couples with high-value assets who wish to separate personal property from marital property before registering the marriage.

7. Arrange for an interpreter and witnesses to be ready on the day of registration.
