Translation within the Apostille chain
In short
The HCCH 1961 Apostille Convention entered into force for Thailand on 22 December 2024, so documents moving between Thailand and another Contracting Party are certified with an Apostille instead of the older embassy legalisation chain. Where the translation sits in that chain depends on the receiving authority.
An Apostille certifies the signature, the capacity of the signatory and the seal on the document. It says nothing about the content and nothing about the accuracy of an attached translation, which is why some authorities want the translation certified separately as well.
Sequence errors are expensive. Ask the receiving authority whether it needs the Apostille on the original, on the translation, or on both, before anything is submitted — reversing the order means going back to the start of the chain.
What we need from you
- The original document and the issuing authority
- Destination country and the receiving institution
- Confirmation of where the Apostille must sit in the chain
- Number of certified sets required
Watch out
Documents from a non-Contracting State still follow legalisation — the Apostille route is not universal.
