Consular and Embassy Legalisation — The Whole Chain, From Translation to Destination in Thailand
Thai documents are rarely refused on content; they are refused because one layer of authentication was skipped.
Quick answer
Thai official documents used overseas must be authenticated by the Legalisation Division of the Department of Consular Affairs and, in many cases, by the destination country's embassy in Thailand. Thai-language records need translation first, and the translation is authenticated too. We run the entire chain, including queueing and follow-up. From THB 3,000 per document, excluding government fees.
From THB 3,000 — From THB 3,000 per document for the handling service; consular and embassy fees are charged at cost. · Standard 5–10 business days; expedited 2–3 business days

Who this is for

- Dispatch of the legalised set to the recipient overseas
Documents to prepare

- Any special requirement stated by the destination embassy
How it works
5-step process
- 1
Map the chain before paying for translation
Some countries want the translation in their own official language, not English, and getting that wrong restarts the whole chain.
- 2
Re-issue records that are old
The consular department and many embassies expect the record to be under six months old.
- 3
Allow for queues and embassy holidays
Each mission keeps its own holiday calendar, which is why rush jobs slip more often than people expect.
- 4
Inspect every seal before the pack leaves Thailand
One faint stamp or a missing signature sends the pack straight back for correction.
- 5
Keep a digital copy of every layer
When the recipient asks about the order of authentication, scans of each stage answer without reopening the file.
FAQ
Frequently asked questions
Can Thailand issue an apostille?
This has to be verified case by case, since practice shifts with convention membership and internal regulation, so we confirm with the consular department and the destination mission before starting.
How do I use a foreign document in Thailand?
Authenticate it in the issuing country and at the Thai embassy there, then render it into Thai and put the rendering through consular authentication as a separate layer.
What are the government fees?
They are per document and differ between standard and express service; we quote the rate posted on the filing day and pass on the official receipts.
Can this be done without the owner attending?
Yes, with a mandate and a copy of the owner's identification, which is the normal route for clients living overseas.
The translation was rejected — what now?
We correct the wording against the stated objection and refile; most rejections come from transliterating names and official titles differently from the accepted usage.
When does legalisation have to be repeated?
When the recipient imposes a validity window, or when the underlying facts change, such as a new surname or marital status.
