Country legalisation guides — 6 destinations
What a Thai document has to pass through before a foreign authority will accept it: certified translation, notarial certification by a Thai lawyer registered with the Lawyers Council of Thailand, legalisation by the Department of Consular Affairs, and — where required — attestation by the destination country’s embassy in Bangkok.
The Apostille timeline for Thailand
Thailand deposited its instrument of accession to the 1961 Hague Apostille Convention on 30 June 2026; the Convention enters into force for Thailand on 28 February 2027. Until that date the existing two-step legalisation chain still applies to every destination, including countries that are already Apostille members. Source: HCCH status table (Convention 12).
Apostille-member destinations (3)
These countries accept an Apostille from a member state. Thai documents will be eligible for a Thai Apostille once the Convention takes effect for Thailand.
Embassy-legalisation destinations (3)
These destinations require the full chain, ending with attestation at the embassy or consulate in Bangkok.
Ask before you file
Embassy requirements change without notice and several missions accept documents by appointment only. Tell us the destination, the document type and your deadline and we will confirm the current chain in writing — phone 083-249-4999, LINE @NYC168, or info@nyclegal.co.th.
