Thai Marriage Extension: The 400,000 Baht Test, Same-Sex Spouses and Documents

A foreigner legally married to a Thai national and holding a Non-Immigrant visa can extend stay for up to one year at a time. In a marriage between a man and a woman, the foreign husband must show 400,000 baht held in a Thai bank for the 2 months before filing, average income of at least 40,000 baht a month, or a combination reaching 400,000 baht. For same-sex and gender-diverse marriages, either spouse or both together may meet the test.

Who qualifies

The marriage must be registered at a Thai district office or a foreign marriage recorded there, and the couple must live together in fact. Since the Marriage Equality Act took effect on 23 January 2025, same-sex spouses qualify on the same basis. The applicant needs a Non-Immigrant visa, usually a Non-O obtained abroad or by change of status in Thailand.

The financial test

Deposit: at least 400,000 baht in a bank in Thailand, held throughout the two months before filing.
Income: average income of at least 40,000 baht a month.
Combined: income and savings together reaching 400,000 baht for the year.
A foreign wife of a Thai husband has no stated money test in the order, though offices may ask for other evidence of support.

Documents offices commonly request

Marriage certificate (Kor Ror 2 or Kor Ror 3) and, for foreign marriages, the Kor Ror 22 record.
Thai spouse's ID card and house registration.
Photos of the couple at home and a location map.
Bank letter and updated bank book dated close to filing.
TM.30 receipt for the address and signed passport copies.

Interview and home visit

Both spouses usually attend to give statements. Many offices issue an 'under consideration' stamp first and may visit the home before granting the full year. Prepare the home and keep the same address throughout.

Foreign documents and the apostille change

A marriage certificate issued abroad must be legalised and translated before it is recorded in Thailand. Thailand acceded to the Apostille Convention on 30 June 2026 and it applies from 28 February 2027; until then consular legalisation is still required.

How we help

We check the marriage records and money evidence against the order, prepare the statements and photo set the responsible office expects, and stay with you through the under-consideration period. We cannot promise approval.

Frequently asked

Can my Thai spouse hold the 400,000 baht?

In a man–woman marriage the order places the test on the foreign husband's account. In same-sex and gender-diverse marriages either spouse may meet it.

Can I work on a marriage extension?

A marriage extension allows a work permit application by a Thai employer, but you may not work until the permit is issued.

What happens if we divorce?

The basis for the extension ends. Get advice promptly on changing status or leaving before the permission is cancelled.
