MFA Legalization Division at a glance
Almost every long paper trail in a foreigner's Thai life passes through this office. A marriage registration, a Thai birth certificate for a child born here, a police clearance, a degree certificate, a company document or a translated passport generally needs the Ministry of Foreign Affairs stamp before another country's authorities — or a Thai agency, bank or school — will accept it.
The Legalization Division sits on the 3rd floor of the Department of Consular Affairs building at 123 Chaeng Watthana Road, along the same road as the Chaeng Wattana immigration and government complex. Telephone 0-2575-1056 to 0-2575-1059.
Address: Legalization Division, 3rd floor, Department of Consular Affairs, Ministry of Foreign Affairs, 123 Chaeng Watthana Road, Thung Song Hong, Lak Si, Bangkok 10210
Hours: Mon–Fri 8.30–14.30 (the Ministry's own published service hours); closed weekends and public holidays; independent guides publish a later close, so rely on the time printed on your booking confirmation
Nearest station: Chaeng Watthana 14 (MRT Pink Line, PK11) and Government Complex (PK12) both sit on Chaeng Watthana Road within reach of the Consular Affairs building

Notable facts
- Appointments are booked online through the Ministry's qlegal system before you visit. Walk-in service is not something to count on, and slots in busy periods are commonly taken a week or two ahead.
- Sources disagree on the exact closing time. The Ministry's own service page states 8.30–14.30, while several independent legal and expat guides publish 8.30–15.30 or a split morning-and-afternoon window. We report the Ministry's own figure rather than pick between them — the time on your booking confirmation is what governs.
- Documents in a language other than Thai or English usually need a certified translation first. The Ministry certifies a translation; it does not produce one for you.
- This is a different building from the Ministry of Foreign Affairs headquarters at 443 Sri Ayudhya Road in Ratchathewi. Going to the wrong one costs most of a day, and the two are on opposite sides of the city.
