Thailand Joins Apostille Convention (Enforcement Comes Later)

This is good news.

The current process (still in effect) to officialize Thailand documents for international use is quite tedious and complicated.

That will finally change when Thailand's entry into the apostille convention is finalized (enforced).

That will happen, the process has officially begun, but the timing is not yet known.

Thailand’s Accession to the Apostille Convention

On 9 December 2025, the Cabinet passed a resolution approving Thailand’s accession to the Convention Abolishing the Requirement of Legalisation for Foreign Public Documents, which is one of the key conventions under the framework of the Hague Conference on Private International Law (HCCH). Accession to this Convention will help reduce procedures and costs related to document legalisation, thereby providing greater convenience for members of the public and the business sector necessitating document legalisation.

Thailand approved its accession to the Apostille Convention on December 9, 2025, which will simplify the process of legalizing documents for international use. This change will allow a single apostille certificate to confirm the authenticity of documents, replacing the previous multi-step consular legalization process.
