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 checkHow 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. 1. Confirm the receiving authority in writing

    Get the authority name, country, and the required attachment form — translation requirements differ by destination.

  2. 2. Check who signs the certification

    The named translator, their qualification, and a reachable contact must appear — not just a company stamp.

  3. 3. Request a sample certification page

    Compare its layout with the sample the receiving authority publishes, before paying.

  4. 4. Agree the name-spelling policy

    Names must match the passport exactly; put free correction of mismatches in the work order.

  5. 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.

Additional frequently asked questions

What kind of translation do authorities accept?
Most authorities require a translation accompanied by a certification statement identifying the translator and the date. For overseas use, the translation itself usually has to be certified by the Department of Consular Affairs or another body named by the destination.
What is the correct certification order?
The common chain is translate, certify the translation, certify at the Department of Consular Affairs, then Apostille or destination-embassy legalisation. The exact order depends on the recipient's rules and should be confirmed before work starts.
How should personal names be spelled?
Exactly as they appear in the passport, character for character. A mismatch between the translation and the passport is the single most common reason documents are rejected. Attach name-change evidence if the name has changed.
Which languages are supported?
Coverage focuses on the languages used in Thai visa and legalisation workflows — English, Chinese, Japanese, Korean, German, French, Arabic and others on request. Scope and requirements are confirmed case by case by phone, LINE or email.
Are original documents required?
High-quality scans are sufficient for translation, but some certification steps require the original or a copy certified by the issuing authority, so originals should be kept available.
Does a translation expire?
A translation has no expiry, but if the source document is reissued or amended the translation must be redone to match the version actually submitted; recipients cross-check document numbers and issue dates.

How this connects to the next step

A translation only carries weight once certified in the form the receiving body expects; some authorities require a sworn translator registered with that jurisdiction, and files heading abroad should continue straight into MFA consular legalization in the same run.

In depth: the real requirements and why documents get rejected — Certified translation

Written from the competent authority's published rules, not marketing copy.

"Certified translation" means different things in different jurisdictions. In some it is a translation the translator signs as accurate; in others the translator must be registered with a court or public authority; in others still the translator's signature must itself be certified. Choosing the wrong category causes rejection even when every word is correct.

Conditions you actually have to clear

  • The translation should be permanently bound to the copy it was made from, so the source version remains traceable.
  • Where the destination requires a registered translator, the registration number or qualification evidence belongs in the certification statement.
  • Any change to the original after translation — even one additional stamp — requires the translation to be updated to match.

Common causes of rejection

  • Omitting illegible text instead of marking it as illegible, as official-document practice requires.
  • Delivering the translation as a standalone file with no link to the source document.

Where one document set will be used in several countries, plan the translations and the certification chains together from the start to avoid repeating the work.

Practitioner guidance — General and specialised document translation

Competent authority: Department of Consular Affairs, Ministry of Foreign Affairs (when translation certification is required)

Practitioner guidance

  • If several countries are involved, translate into English first as a pivot, then decide on further target languages.
  • Keep translation files and certificates together; the next filing usually reuses the same set while still valid.
  • Confirm which certification system the receiving authority accepts before ordering — MFA-certified, NAATI, sworn translator and Ministry of Justice routes are not interchangeable.
  • Spell names exactly as printed in the passport, including middle names and prefixes.
  • Obtain freshly issued civil-registration extracts before translating; many authorities accept only documents issued within roughly 3–6 months (verify with the receiving office).

Pitfalls — why documents get rejected

  • Bank documents without an original bank stamp, which invalidates an otherwise correct translation.
  • Translating only selected pages when the authority requires the complete document.
  • Name spelling in the translation does not match the passport — the single most common rejection cause.
  • Submitting an old photocopy instead of a freshly issued registry extract.
  • The source document expires while the translation waits in the certification queue.
