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.
Who needs this
- Applicants sending Thai birth, marriage, divorce or house registration documents overseas
- Companies sending Thai corporate records to foreign registries or banks
- Anyone whose destination embassy will only stamp files already legalised in Thailand

Overall timing
Translation plus standard legalisation usually runs 3–6 business days end to end. Express handling shortens the counter stage but does not change how long the issuing district office needs to re-issue an original.
Advice from our team
- Order two certified copies of any civil registry document — a spare avoids a full restart if one is retained
- Send us a photo of the destination's requirement list; wording differences change which layer is needed
- Check the exact Latin spelling of every name before translation is finalised
Things to watch out for
- The department authenticates signatures and seals; it does not verify the factual accuracy of the content
- Documents with handwritten amendments or missing seals are commonly returned
- Some destinations refuse translations not prepared to their own template
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.
