Legalising Thai Documents for Use Abroad

Published 6 Oct 2026

Thai documents for use abroad are legalised by the Department of Consular Affairs of the Ministry of Foreign Affairs, through its Contracts and Legalisation Division, and by Thai embassies and consulates abroad. Legalisation covers translations, copies and signatures. The receiving country or authority decides what it needs, so the first step is to confirm its requirements.
