Recommended document translation (Thai nationals) — verifiable selection criteria
Short answer
Choose a translation provider by where the document is going, not by price. For consular or embassy filing, the translator must be willing to sign the certification page and attach an ID copy. For court or justice-sector use, confirm the translator is registered with the Ministry of Justice, and always ask to see a sample certification page before ordering.
Searches like "recommended translation agency" usually appear the moment a filer learns their self-made translation was rejected. This page does not rank providers; it gives verifiable criteria so any provider can be compared on the same standard.
Provider verification criteria
| What to check | How to verify |
|---|---|
| Is the certifying person actually licensed? | Ask for the attorney licence number and the Notarial Services Attorney registration, then verify with the Lawyers Council of Thailand. |
| Does the provider ask where the document is going first? | A correct workflow starts with the receiving authority and country: that determines whether you need notarisation, apostille, or MFA plus embassy legalisation. |
| Is the turnaround quoted in working days? | Ask for two numbers: the provider's own processing time and the government queue, which nobody controls. A single blended number is usually unreliable. |
| Is there a verifiable office address? | Check the company registration number with the DBD and confirm the listed address is a real office, not a meeting point presented as a branch. |
| Does the quote separate government fees from service fees? | Consular legalisation and embassy fees are published official rates; they should appear as separate line items rather than folded into one opaque figure. |
| Are the cases they cannot handle disclosed upfront? | Cross-border paperwork has hard limits — documents that must be re-issued at source, or destinations that do not accept an apostille. A provider who never mentions limits is a warning sign. |
Checks to run before you order
1. Confirm the receiving authority in writing
Get the authority name, country, and the required attachment form — translation requirements differ by destination.
2. Check who signs the certification
The named translator, their qualification, and a reachable contact must appear — not just a company stamp.
3. Request a sample certification page
Compare its layout with the sample the receiving authority publishes, before paying.
4. Agree the name-spelling policy
Names must match the passport exactly; put free correction of mismatches in the work order.
5. Plan the downstream certification
Ask upfront whether the translation will be legalised or apostilled afterwards, so it is not redone.
Frequently asked questions
Can I translate an official document myself?
Generally no. The Department of Consular Affairs certifies translations that carry an accountable signing translator and match the original; self-translations are usually returned.
Are translation and certification the same step?
No. Translation renders the text; certification is an authority confirming a signature or accuracy. The order is dictated by the destination.
Can very old or handwritten documents be translated?
Yes, but legibility must be assessed first. If parts are unreadable, request a fresh certified copy from the issuing office before translating.
Original or copy?
It depends on the destination. Consular legalisation usually needs the original or an issuer-certified copy; internal corporate use often accepts copies.
What if the name spelling differs from my passport?
Follow the passport spelling and tell the translator upfront. If the source document genuinely differs, a same-person affidavit may be required.
Does same-day translation affect quality?
Short standard-format records can be fast, but contracts and technical files need review time — an error returns the entire set.
Must everything be translated into English?
Not always. Some countries require their own official language — German, French, Japanese — so check the receiving authority's rule first.
Do translations expire?
The translation itself does not expire, but destinations often cap the age of the source document (commonly 3–6 months), which forces a re-translation.
