An apostille is a standardised certificate under the Hague Apostille Convention confirming a signature and seal on a public document. Thailand's Convention takes effect on 28 February 2027; as of September 2026, Thailand does not issue apostilles for Thai documents. Thai Law & Accounting checks the receiving authority's requirement and helps prepare translations and the current consular legalisation route. Send scans to LINE @THAIL for a scope review.
What the apostille actually certifies
An apostille verifies the authenticity of the signature, the capacity of the signatory, and the seal or stamp on the document. It does not verify the content of the document itself. That distinction matters because receiving institutions often phrase their request loosely: some ask for a 'certified copy', some for a 'legalised document', and some specifically for an apostille. Each is a different layer, and filing the wrong one is the most common reason a file has to be redone.
Once the Convention takes effect for Thailand, eligibility for an apostille will depend on the document and competent authority. For current consular legalisation, confirm whether the recipient requires an original or a fresh certified extract; an uncertified photocopy is generally insufficient. Check the issuing office and receiving authority before ordering a new copy.
- Certifies signature, capacity and seal — not the content
- Not issued for Thai documents as of September 2026
- Convention enters into force for Thailand on 28 February 2027
- Private documents must be notarised or certified upstream first
The order of operations we use
We start from the receiving institution's written requirement and work backwards. Before 28 February 2027, do not assume an Apostille can be issued for a Thai document, even if the destination is a Convention member. We confirm the available consular and embassy steps, refresh the underlying document where needed, and arrange the requested translation. We return the completed file with scans for your records.
Names are the single most frequent failure point. The spelling on the translation must match the passport exactly, including middle names and transliteration choices. Where a person has changed name, the supporting change-of-name record travels with the file.
- Confirm the destination requirement in writing
- Obtain a recent certified original or extract
- Prepare and proofread the certified translation
- File for current consular legalisation and embassy attestation if required
- Return the file with scans and a record of what was issued
