Certified Translation in Thailand — By Document, Language and Destination
A certified translation is only accepted when it uses the certification system the receiving authority recognises — Thai MFA legalization, a sworn translator on a foreign court register, or NAATI for Australia. MFA stamps cost THB 200 each with a 2-3 working day turnaround, or THB 400 for same-day express lodged before 11:30. Until 28 February 2027 most destinations still require their embassy in Bangkok to countersign.
The five working steps
- 1. Confirm which certification system the receiver requires
Thai MFA legalization, a sworn translator on a foreign court register, NAATI for Australia, or a translator's declaration. The wrong system is the most common reason a translation is rejected.
- 2. Send a clear scan of the source document
The translation must match the issuing authority's exact spelling of names, dates and document numbers. We flag missing prior certifications, such as an Amphur or Department of Provincial Administration stamp, before translating.
- 3. Produce the certified translation
The translator prepares the target-language text with a signed certificate of accuracy in the layout the receiving authority accepts, keeping names consistent with your passport.
- 4. Legalize the translation where required
For Thai documents going abroad, file at the Legalization Division, Department of Consular Affairs: THB 200 per stamp standard, 2-3 working days, or THB 400 express when lodged before 11:30.
- 5. Add the destination step, embassy or Apostille
Until 28 February 2027 most destinations still need their embassy in Bangkok to countersign. After that date Hague Convention states accept a single Apostille instead of the embassy step.

Frequently asked questions
What certification does a translated document need to be accepted in Thailand?
Foreign documents need three layers: origin-country certification (an Apostille for Hague members, or origin MFA plus Royal Thai Embassy legalization for non-members), a Thai translation that mirrors the original layout, and translation certification by the Department of Consular Affairs at Chaeng Watthana. Miss any layer and the Amphur, Immigration, Land Office or DBD will refuse the filing.
How much does MFA translation certification cost?
Government legalization fees are THB 200 per stamp for the standard service (documents returned in two to three working days) and THB 400 per stamp for the same-day express service on straightforward files. Stamps are counted per page requiring certification, not per set. Translation and agency handling fees are separate from the government fee.
How long does certified translation plus legalization take?
Standard civil records translate in one working day; corporate documents and court judgments take two to three. Adding consular certification, plan for three to five working days end to end. Express handling can compress the whole chain to one or two working days when the source documents are already clean.
Why do translations get rejected most often?
Name spellings that differ from the passport, dates left in the Buddhist calendar, uncertified photocopies, registrar signatures that do not match the specimen on file, and translations that reorganize the original layout. We proof every source document against these five checks before translation begins.
Does Thailand's 2026 Apostille accession remove the need for translation?
No. An Apostille authenticates the signature and seal on the issuing document; it says nothing about language. Apostilled foreign documents still need a Thai translation certified by the Department of Consular Affairs before any Thai authority will accept them. What disappears is the second embassy stamp, saving roughly five to ten working days.
Can you translate from languages other than English?
Yes — Chinese, Japanese, Korean, German, French, Spanish, Russian, Italian, Arabic, Vietnamese, Burmese, Lao, Khmer, Dutch, the Nordic languages, Polish, Czech, Portuguese, Turkish, Persian, Hindi and more. For rarer languages the safest route is often an embassy-issued English version first, then Thai; we advise which route the receiving authority will accept before quoting.
What documents do I need translated to marry a Thai national?
An Affirmation of Freedom to Marry from your embassy, your passport, and, if applicable, a divorce decree or a former spouse's death certificate. All must be translated into Thai and certified by the Department of Consular Affairs, and most district offices want them issued within the previous three months.
Do I need certified translations for a Thai work permit?
Yes. The Department of Employment requires degree certificates, transcripts and employment references in Thai or English with certification. Foreign qualifications must clear an Apostille or embassy legalization before translation, so start the paperwork four to six weeks before your intended filing date.
How are foreign corporate documents prepared for company registration in Thailand?
The parent company's Certificate of Incorporation, memorandum and board resolution must be notarized abroad, apostilled or legalized by the Royal Thai Embassy, then translated into Thai and certified at the Department of Consular Affairs. The DBD generally wants documents issued within six months, and the transliterated company name must match the name reserved in its system.
Can I use a power of attorney signed overseas for a Thai property transfer?
Only after the full chain: notarization abroad, Apostille or Thai embassy legalization, Thai translation, and consular certification of that translation. The Land Office reads powers of attorney narrowly, so list each authorized act explicitly — sign the transfer, receive proceeds, pay taxes — rather than granting a general authority.
Do you accept scanned copies, or do you need originals?
We can start translation from a clear scan, but consular certification requires the original or a copy certified by the issuing authority with a wet signature and seal. Self-certified photocopies are refused. Courier the originals to us while we prepare the draft, and you lose no time.
How are translation fees calculated?
Fixed-format civil records are priced per document. Variable-length material — contracts, judgments, financial statements — is priced per standard page or per word. Rare language pairs carry a premium because the pool of translators whose work the consular office accepts is small.
