BANGKOK, THAILAND – Same-sex couples have been able to marry in Thailand since 23 January 2025, and the reform has now directly reshaped immigration rules for foreign spouses.
Marriage visas now open to all couples
Foreigners married to a Thai citizen were now entitled to apply for a Non-Immigrant O visa, commonly known as the marriage visa, regardless of the gender of either spouse. The visa allowed a legal stay of one year and was renewable annually. A civil marriage registered at the Amphoe district office remained a strict prerequisite; purely traditional ceremonies without registration did not count.
After the Marriage Equality Act came into force, the Thai immigration authority implemented visa pathways for same-sex spouses. Foreign partners in a legally registered marriage with a Thai national submitted the same application to the same offices under the same conditions as mixed-gender couples. This applied equally to woman–woman, man–man and mixed-gender marriages.
What the Marriage Equality Act changed
Parliament passed the Marriage Equality Act in June 2024 by an overwhelming majority. King Vajiralongkorn signed it on 24 September 2024, and it took effect 120 days later. Thailand thus became the first country in Southeast Asia and the third in Asia, after Taiwan and Nepal, to legally recognise same-sex marriages.
Technically, the reform amended the Civil and Commercial Code. More than 60 sections of the code were adjusted, replacing the gendered terms “husband” and “wife” with the gender-neutral “spouse”. As a result, same-sex couples now enjoyed the same rights and obligations as heterosexual couples, including access to a spouse-based visa.
The financial hurdle for a one-year stay
Applicants for the one-year extension of stay had to meet one of two financial conditions. One option required at least 400,000 Thai baht on an account with a Thai bank held solely in the applicant’s name. The alternative was a documented monthly income of at least 40,000 baht; joint accounts were generally not accepted.
For the bank-balance route, the funds had to be on the account for at least two months before the application, and for a first renewal some offices, such as Pattaya or Samut Prakan, demanded three months. The money needed to arrive as an international transfer (Foreign Telegraphic Transfer, FTT), not as a cash deposit or domestic transfer. Users of services like Wise were advised to check whether the incoming funds appeared as FTT on the bank statement, as this was not guaranteed.
Core documents for immigration officers
The foundation of every application was a marriage certificate registered in Thailand. Couples who had married abroad had to re-register the marriage at the Amphoe and present the Kor Ror 22 family status registration form. Officers also requested the Thai partner’s Tabien Baan house registration book, a hand-drawn sketch of the residence and joint photographs of the couple at home and in everyday life.
Documents issued abroad had to be certified by the relevant embassy in Bangkok and then legalised by the Thai Ministry of Foreign Affairs (MFA). Because Thailand was not a member of the Hague Apostille Convention, an apostille alone was not sufficient. The embassy stamp was mandatory, followed by MFA legalisation and translation into Thai by an approved translator.
Where foreign papers are certified
German citizens had to contact the German Embassy in Bangkok. It issued income certificates and document certifications only upon personal request, with no option for postal submission or online processing. In-person appearance at the embassy was obligatory; Austrian and Swiss nationals had to turn to their respective consulates.
Once the embassy had certified a document, MFA legalisation had to follow before it could be used at Thai immigration offices. Applicants who skipped this step or followed the wrong order had to repeat the entire procedure. Germans preparing for marriage while still in Germany also needed to have their marriage certificate legalised by the Royal Thai Embassy in Berlin or the Consulate-General in Munich.
Procedure at the Immigration Office
Those without a Non-Immigrant O visa first had to obtain one, either from a Thai embassy in their home country or, after entering on a tourist visa, within Thailand. The initial Non-O visa was valid for 90 days. Before this period expired, applicants had to submit their request for the one-year extension at the local immigration office responsible for the province where the couple lived.
After submitting all documents, applicants received a provisional 30-day stamp while officials examined the file. In some provinces, immigration conducted unannounced home visits to verify the couple’s genuine cohabitation. Once checks were completed, the final one-year stamp was issued; anyone leaving Thailand during this process needed a re-entry permit, otherwise the permission to stay lapsed.
Common mistakes that lead to refusals
The most frequent reason for refusal was incomplete or improperly legalised paperwork. Missing signatures on copies, incorrect dates in bank books or bank statements without a same-day final entry could be enough for rejection. Many offices also demanded that the bank statement be updated by a manual transaction on the day of application.
Another recurring error concerned the required holding period for funds. The bank balance needed to originate from an international source and remain untouched on the account for at least two months. Applicants who deposited money shortly before applying or transferred it from another Thai account often failed this test. Those relying on the income method of 40,000 baht per month had to present 12 months of continuous incoming payments on their statements.
Reporting duties and renewals
The annual extension of stay did not exempt foreigners from the 90-day reporting obligation. Anyone residing continuously in Thailand had to report their current address to immigration every three months, either in person, by post or online. Online reporting closed seven days before the due date, while in-person reporting was allowed up to seven days after; the first report always had to be done in person.
The one-year permission needed to be renewed before expiry, as there was no automatic extension. The same conditions applied as for the initial application, with one main exception: some immigration offices required that the bank balance be on the account for three months before renewal. If the marriage ended in divorce, the visa’s legal basis ceased to exist and immigration could immediately revoke the right to stay.
Alternatives to the marriage route
Those who did not meet the financial thresholds for a marriage visa, or who did not wish to marry a Thai citizen, had other options. From age 50, the Non-Immigrant O-A retirement visa was available, demanding 800,000 baht in a Thai bank or a monthly income of 65,000 baht, plus health insurance coverage of at least 3,000,000 baht. People working remotely for foreign clients could consider the Destination Thailand Visa (DTV), which offered a five-year validity, stays of 180 days per entry and no work permit requirement, but required proof of assets of 500,000 baht.
An education visa linked to a language course was legally possible but not a long-term solution. It required genuine regular attendance at a licensed school and did not allow free residence independent of studies. Anyone aiming for permanent life in Thailand ultimately needed a long-term visa with a stable legal basis.
Next steps for couples
Same-sex couples planning to use the marriage visa first had to ensure that their union was registered at the Amphoe. Those married abroad needed to re-register the marriage in Thailand. They then had to prepare documents by legalising the foreign marriage certificate through their embassy, the MFA and an approved translator, opening a Thai bank account and transferring funds at least two months before applying by FTT.
Applicants uncertain about the specific requirements of their local immigration office were advised to consult a specialised visa service in advance, as demands varied by province. Thorough preparation helped avoid costly repeat submissions and long waits at immigration counters.
Editorial notes and legal caveats
The guidance was based on the current legal situation following the Thai Marriage Equality Act, in force since 23 January 2025, and on existing police regulations for the Non-Immigrant O visa, particularly Police Order 327/2557. Immigration rules and banking requirements could change at short notice. The editors therefore recommended seeking advice from a lawyer licensed in Thailand or an official visa agency before submitting an application.
