The Thailand marriage visa is a Non-O: first a stay of up to 90 days, then a 1-year extension with 400,000 baht in the bank or 40,000 baht income a month.

Last checked: 11 October 2026

In short (as of 11 October 2026)

  • The route: a Non-Immigrant O visa based on family in Thailand (stay of up to 90 days), followed by an extension of up to 1 year at a time at immigration, for 1,900 baht.

  • Financial requirement if the foreign partner is the husband: 40,000 baht average income a month, or 400,000 baht for at least 2 months in a bank in Thailand, or a combination totalling 400,000 baht.

  • You and your partner attend an interview together, and you hand in 4 family photos outside and inside the house plus a floor plan.

  • You can apply through the e-Visa system (70 euros in The Hague, 80 euros in Brussels) or convert inside Thailand (2,000 baht, with more than 15 days of your stay left).

  • If you travel without a re-entry permit (1,000 or 3,800 baht), your extension lapses.

This article is for Dutch and Belgian nationals who are married to a Thai national, or plan to be, and want to live with that partner in Thailand. The general Thai rules in this guide apply to all nationalities; the parts about embassies and documents are written for Dutch and Belgian passport holders, so if you hold another passport, check the requirements of the Thai embassy or consulate that serves you.

What the Thailand marriage visa is

Officially, there is no separate "marriage visa". It consists of two steps:

  1. A Non-Immigrant O visa, purpose "To stay with Thai family residing in Thailand (more than 60 days)", code O8 at the embassy in The Hague. Single entry, valid for 3 months, stay of up to 90 days from arrival.

  2. An extension of stay based on "family member of a Thai national", for up to 1 year at a time, renewed every year.

The conditions are set out in Police Order 327/2557 (Royal Gazette 8 August 2014, in force since 29 August 2014) and in the checklists of the Immigration Bureau (1 November 2023) and Immigration Division 1 in Bangkok.

Who qualifies

  • You are legally married to a person of Thai nationality, and the relationship exists both on paper and in reality (de jure and de facto).

  • You hold a Non-Immigrant visa (Non-O), obtained through the embassy or by conversion in Thailand.

  • Foreign husband, Thai wife: you meet the requirement of 40,000 baht a month or 400,000 baht.

  • Foreign wife, Thai husband: the checklist "staying with Thai husband" mentions no income or savings requirement.

The checklists describe a marriage between a man and a woman. According to the Dutch government, you can also marry a person of the same sex in Thailand; the immigration sources consulted mention no separate requirements for that. Ask your immigration office which conditions then apply.

Route 1: applying from the Netherlands or Belgium

You apply through thaievisa.go.th. The Hague only handles applications from people who are in the Netherlands for the entire procedure; Brussels automatically rejects applications from outside Belgium or Luxembourg and from people in Thailand.

Documents according to The Hague (31 August 2026) and Brussels (leaflet November 2023):

  • Passport page with personal details and a passport photo no more than 6 months old

  • A document showing your current place of residence

  • 40,000 baht income a month or a balance of 400,000 baht, for example bank statements for the last 3 months

  • Details of your partner in Thailand, such as the Thai ID card

  • Proof of the relationship, such as a copy of the marriage certificate

Whether the marriage certificate must be translated or legalised is not stated in the lists: ask the embassy. Both embassies may ask for an interview or extra documents.

Route 2: converting inside Thailand

If you are in Thailand visa-exempt or on a tourist visa, you convert to a Non-O at immigration. According to Immigration Division 1 (February 2022):

  • You must have more than 15 days of your stay left; after an overstay it is not possible.

  • Form TM.87 (visa-exempt) or TM.86 (tourist visa), 1 passport photo, passport copies, 2,000 baht. You receive up to 90 days.

  • Your partner's ID card and house registration. Marriage in Thailand: Khor Ror 2 and Khor Ror 3, and a copy of your certificate of single status from before the marriage. Marriage abroad: the foreign marriage certificate and Khor Ror 22.

  • The certificate of single status and the documents of a marriage abroad must be translated into English and legalised by your embassy and by the Legalization Division of the Thai Ministry of Foreign Affairs.

  • Foreign husband: an income statement from your embassy (40,000 baht a month) or a Thai bank letter with the bank book (400,000 baht), updated on the day of application. Thai husband: an employment certificate from him.

  • About 6 photos of the family and the home (house number and interior), a rental contract or proof of ownership with a floor plan, and proof of the address notification (TM.30).

  • You and your partner both attend in person.

The 1-year extension

According to checklist 7-4 of the Immigration Bureau (1 November 2023) and Immigration Division 1:

Financial requirement (foreign husband): an average annual income of at least 40,000 baht a month, or at least 400,000 baht held for the past 2 months in an account with a bank in Thailand, or income and savings together of at least 400,000 baht.

Documents:

  • Form TM.7 with 1 passport photo (no more than 6 months old) and passport copies, including proof of the address notification (TM.30) and the 90-day report

  • Marriage in Thailand: Khor Ror 2 and Khor Ror 3; abroad: marriage certificate and Khor Ror 22. Previously divorced: divorce certificate and registration

  • Your partner's ID card and house registration; documents of any children

  • Savings: a bank letter and a copy of the bank book, updated to the day of application. Income from abroad: a letter from your embassy in Bangkok stating at least 40,000 baht a month. Work in Thailand: work permit, employer's certificate and tax documents

  • If you do not live at the address of the house registration: a rental contract or a statement from the owner, with a copy of the owner's ID card and house registration or proof of ownership

  • 4 family photos no more than 6 months old (2 outside with the house number visible, 2 inside) and a floor plan

  • 1,900 baht

You and your partner attend in person for an interview; you show the originals and sign every copy.

While your case is being considered, the officer may give you an "under consideration" stamp, for a total of no more than 30 days after the end of your stay. If you are refused, you leave within 7 days after the end of your stay (Police Order 327/2557, articles 3 and 4).

Proof of income: the Netherlands and Belgium differ

The Netherlands. The embassy in Bangkok issues a visa support letter (visumondersteuningsbrief) stating your income: 50 euros, plus 2 euros for EMS. Email ban-ca@minbuza.nl first. Only income that the Dutch Tax Administration (Belastingdienst) can verify counts; savings do not. The embassy does not check the Thai requirement and warns that immigration may refuse the letter in the future.

Belgium. The embassy in Bangkok does not issue support letters. It does legalise the signature on a sworn statement (verklaring op eer) about your income, with a note that this says nothing about the content. Since 1 January 2026 this is only possible in person, by appointment.

Whether your office accepts these documents as a "letter from the embassy" is up to the office. Ask beforehand.

Getting married in Thailand and having the marriage recognised

Dutch nationals marry at a Thai district office, not at the embassy. According to NederlandWereldwijd, a certificate of no impediment to marriage (verklaring van huwelijksbevoegdheid) is not needed for Thailand. You do need:

  1. A statement of marital status (verklaring over de burgerlijke staat), applied for in person by appointment at the embassy in Bangkok, with the marriage statement application form (30 euros). Among other things, you show an official proof of single status; if you are deregistered from the BRP (the Dutch population register), as an RNI extract (Register of Non-Residents).

  2. A witness and income form with 2 Dutch witnesses, signed and legalised at the embassy (26.25 euros).

  3. A copy of your passport legalised at the embassy (26.25 euros); an ID card cannot be used.

  4. The statement and the form must be translated into Thai and legalised by the Thai Ministry of Foreign Affairs.

If you live in the Netherlands, you must register the marriage with your municipality; if you live abroad, you can do so voluntarily with the municipality of The Hague. Thai certificates are legalised by the Thai ministry and then by the Dutch embassy (26.25 euros per document).

Belgian nationals need, according to the Belgian embassy in Bangkok (2 September 2026), a certificate of no impediment to marriage (attest van geen huwelijksbeletsel, AGHB). Both future spouses attend in person by appointment with a complete file, for an interview. If there is doubt about a sham marriage, the file goes to the public prosecutor's office (parket) (up to 3 months, extendable by 2). If approved, you receive the certificate, a certified passport copy and a certificate within 4 working days; you have these translated into Thai and legalised by the Thai ministry. After the marriage, you have Khor Ror 2 and Khor Ror 3 legalised, translated and legalised by the embassy. Registration in the Databank Akten Burgerlijke Stand (DABS, the Belgian civil status database) is not compulsory, but recommended.

Apostille. According to the Hague Conference (HCCH), Thailand acceded to the Apostille Convention on 30 June 2026, which enters into force for Thailand on 28 February 2027. The convention only applies between Thailand and contracting states that do not object to the accession within 6 months (article 12); on 11 October 2026 the HCCH table shows no objection from the Netherlands or Belgium. Until 28 February 2027 the legalisation chain above applies; after that date, ask the embassy which route applies.

Costs

Euro amounts next to baht are an indication (ECB rate 9 October 2026: 1 euro = 37.574 baht). Thai fees: Ministerial Regulation No. 27, in force since 26 August 2003.

Not in the table: translation and legalisation at the Thai Ministry of Foreign Affairs. No official fee list was found for these; ask about them at your appointment.

Common mistakes

Depositing the money too late. The 400,000 baht must be in an account in Thailand without interruption for the last 2 months before the application.

Going to immigration alone. Your partner must also attend in person for the interview.

Converting too late. With 15 days or less of your stay left, or after an overstay, a conversion is not accepted.

Leaving without a re-entry permit. Your extension lapses when you leave.

Where the sources contradict each other

  • Photos. For a conversion, Immigration Division 1 (February 2022) asks for about 6 photos; for the extension (November 2023), 4.

  • 12 months of deposits. A notice from the Belgian embassy (1 March 2021) mentions 40,000 baht a month "for 12 months in a Thai account" (translated from the Dutch notice). The Thai checklists do not mention this; they do mention a letter from the embassy.

  • Belgian legalisation fee. The marriage page (2 September 2026) states 20 euros per document, the fee list from 1 October 2026 states 25 euros (1,000 baht). The fee list is the most recent.

What has changed

  • 8 August 2014: Police Order 327/2557 published in the Royal Gazette.

  • 1 November 2023: current checklists 7-3 and 7-4 of the Immigration Bureau.

  • 1 January 2026: the Belgian embassy only legalises own statements in person.

  • 31 August 2026: updated document list of The Hague.

  • 1 October 2026: new fees of the Belgian embassy in Bangkok.

  • 28 February 2027 (announced): Apostille Convention in force for Thailand.
