Directory · Documents & LegalCertified translation & notarization in Thailand.
Getting official documents translated, certified and legalised in Thailand — for visas, marriage, work permits and more — without the rejected-paperwork delays.
← All expat services
01What this is & why you'd need it
Foreigners constantly need official documents in the right language and form: birth and marriage certificates, degrees, police clearances, affidavits and contracts — translated into Thai (or from Thai), then certified, notarized or legalised so an immigration office, the Ministry of Foreign Affairs, an embassy or a Land Office will accept them. The work itself is routine; the cost is the rejected-document delay when a translation isn't certified correctly or a step in the legalisation chain is missed. Knowing which level of certification each authority actually requires — and using a provider who delivers exactly that — saves repeat trips and lost weeks.
02What to look for
- Experience with the exact document and the exact authority you need it for
- Clarity on the level required: certified translation, notarial attestation, or MFA/embassy legalisation
- A provider who states turnaround and price per document in writing
- Accuracy on names and dates — transliteration errors are a common cause of rejection
03Questions to ask before you commit
Q. Exactly what certification does my receiving authority require for this document?
Q. Do you handle the full chain (translation → notarization → MFA/embassy legalisation) or only part?
Q. How will my name be transliterated, and will it match my passport and other documents?
Q. What's the price per document and the realistic turnaround, in writing?
Red flags
Walk away if you see…
- Vagueness about which authority will accept the output — that's where rejections come from
- A translation sold as 'certified' with no recognised certification the authority accepts
- No written quote or turnaround, and no responsibility taken for rejected work
- Inconsistent spelling of your name across documents (a frequent rejection trigger)
What it typically costs
Usually priced per document or per page, with notarization and MFA/embassy legalisation as separate added steps. The cheapest quote is a false economy if the output gets rejected — confirm up front exactly which level of certification your authority needs and get the per-document price and turnaround in writing.
Frequently asked
What's the difference between certified, notarized and legalised?A certified translation is a translation a recognised translator attests is accurate; notarization adds a notarial certification of signatures or copies; legalisation (often via Thailand's Ministry of Foreign Affairs and/or an embassy) is the higher step that makes a document valid for official cross-border use. Different authorities require different levels — confirm which yours needs before paying, because doing too little means rejection and doing too much wastes money.
Why do documents get rejected?Most often because the certification level is wrong for that authority, a step in the legalisation chain was skipped, or a name or date was transliterated inconsistently with the passport. Using a provider who knows your specific receiving office, and keeping name spelling identical across every document, prevents most rejections.
How does this connect to my visa?Visa, marriage-registration, work-permit and property steps frequently require translated and legalised supporting documents. Line this up early — see our visa center and the visa-agents directory — so a missing certification doesn't stall your application at the immigration office.
