Can a Thai translator become a sworn translator?
Not under Thai law — there is no such register in Thailand. Some Thai nationals hold appointments in other countries under that country's rules, which is a different thing.
Sworn translator (Europe) vs Thailand's certification system
Several European countries appoint translators through their courts or ministries; those translators sign and stamp under oath and their translations are accepted directly by domestic authorities. Thailand has no equivalent register, so a Thai document destined for such a country is normally handled as a certified translation, certified by a Notarial Services Attorney and legalised by the Department of Consular Affairs, then legalised by the destination embassy — or, in some cases, translated in the destination country by a locally sworn translator after the Thai original is legalised.
Point-by-point comparison
| European sworn translator | Thai certification chain | |
|---|---|---|
| Legal basis | Court or ministry appointment under national law | No sworn-translator register; certification by contract and professional rules |
| Who signs | The sworn translator, under oath | Translator plus Notarial Services Attorney |
| Accepted directly by | Domestic authorities in the appointing country | Thai authorities and, after legalisation, foreign recipients |
| Where the work happens | Usually in the destination country | In Thailand, before the document leaves |
| Legalisation of the original | Still usually required on the Thai original | MFA legalisation at THB 200 per stamp, THB 400 express |
| Risk if you choose wrong | Translation may be rejected if done outside the register | May need re-translation on arrival by a local sworn translator |
European sworn translator — choose this when
- The destination authority names a court-sworn or ministry-appointed translator
- You have a contact or agent in the destination country who can arrange it
- The document is short and re-translation on arrival is cheap
Thai certification chain — choose this when
- The Thai original must be legalised before it leaves Thailand anyway
- The destination will accept a legalised Thai certified translation
- You need the whole package prepared before departure
Frequently asked questions
Will Germany accept a Thai certified translation?
German authorities commonly require a translation by a translator sworn in Germany, though practice varies by state and office. Ask the specific office in writing before paying for a translation in Thailand.
Should I legalise the Thai original even if I translate abroad?
Usually yes. The destination will want proof that the Thai document itself is genuine, which is what MFA and embassy legalisation provide.
Does the 2027 apostille change this?
From 28 February 2027, apostilles will replace embassy legalisation for convention members, which simplifies proving the original. The sworn-translator requirement is separate and is unaffected.
What does this cost in practice?
Costs split between the Thai side — translation, attorney certification and MFA stamps at THB 200 or 400 each — and any translation done in the destination country. We quote only the Thai side.
Can you coordinate both sides?
We prepare and legalise the Thai side and hand over a package that a destination sworn translator can work from directly, which avoids duplicated work.
Send us a photo of the document plus the written requirement from the receiving authority, and we will map the exact chain — translation, lawyer certification, MFA, embassy — before you pay for anything. Call 094-895-8999 or LINE @Thainotary.
