How does Thailand's 2025 Apostille convention work in practice?
Thailand deposited its instrument of accession to the Hague Apostille Convention on 30 June 2026 and the Convention enters into force for Thailand on 28 February 2027. Apostilles are issued by the MFA Department of Consular Affairs in Chaeng Watthana for 130 Contracting Parties; embassy legalization is no longer needed for those countries. NPT handles the full process in 3–5 working days — contact our team for a quotation.
Detailed Answer
Thailand deposited its accession instrument on 28 February 2027 and the Apostille Convention entered into force for Thailand on 28 February 2027. From that date, a single Apostille certificate issued by the Department of Consular Affairs (Ministry of Foreign Affairs, Chaeng Watthana Road) replaces the previous MFA-then-Embassy legalization chain for any of the 125+ Convention member states (US, UK, all EU, Japan, Korea, Singapore, Australia, etc. ). Non-member destinations (e. g. UAE, Saudi Arabia, Vietnam, Taiwan, mainland China for now) still require traditional consular legalization. NPT workflow: (1) prepare original or notarized copy, (2) translate into Thai if foreign-issued, (3) MFA legalizes underlying document, (4) MFA affixes Apostille sticker, (5) we courier back. Professional fees are quoted after the documents and required steps are reviewed. our service fee is quoted after document review. Standard 3–5 working days, express 1–2 days.
