Legalisation of Documents and Translations at the Department of Consular Affairs

A Thai law office desk with a document set prepared for certification — Legalisation of Documents and Translations at the Department of Consular Affairs

Legalisation at the Department of Consular Affairs (Ministry of Foreign Affairs) authenticates a Thai official document, or a translation of it, so foreign authorities will accept it. Standard service typically takes 2–3 business days after lodgement; express service is shorter where available. Civil registry documents must be recent originals, and translations must follow the department's naming and formatting conventions.

Advice from our team

Things to watch out for

Frequently asked questions

Can I lodge the file myself?

Yes. You can attend in person with your ID; we file on behalf of clients who prefer not to queue or who live outside Bangkok.

Does legalisation expire?

The stamp has no fixed expiry, but the underlying certificate often does — most authorities want documents issued within 3–6 months.

Is legalisation the same as an Apostille?

No. Legalisation is the consular chain used for non-Hague destinations or where the receiving authority specifically asks for it.

Can you handle documents while I am abroad?

Yes, with a signed power of attorney and clear scans we can obtain, translate and legalise most civil registry documents without you travelling.
