How does this service differ from standard translation?
This service goes beyond mere linguistic translation; it includes notarisation of the translation's accuracy by a Notarial Services Attorney, in accordance with the Lawyers Council Regulation B.E. 2546. This grants the document legal validity and international recognition.
Can these documents be used at embassies or the Ministry of Foreign Affairs?
Yes, our notarised translations are widely accepted for submission to various embassies. They also serve as a prerequisite for further legalisation by the Ministry of Foreign Affairs (MFA Chaeng Watthana) if the destination country is not a signatory to the Hague Apostille Convention.
If my original document is in a foreign language, does it need to be translated into Thai first?
If the original document is in English or another language the Notarial Services Attorney is proficient in, a prior translation to Thai might not be necessary. We can translate directly from the source language to your target language and then notarise the translation.
Why certified translations get rejected — and how to fix it
Short answer: Translations fail on name spellings that diverge from official records, untranslated seals and signatures, Buddhist/Gregorian date conversion errors, and missing translator certification in the recipient's required wording. Reissue a corrected version with the accepted certification statement.

Add seal and signature descriptions and reissue
Estimated time cost

Translator certification wording not accepted
Underlying cause

The recipient also required MFA or embassy certification of the translation
Prevent before filing
Clarify whether certification of the translation itself is required
How to fix a rejection
Run the translation through the prescribed chain
Estimated time cost
Adds roughly 3–10 working days (estimate)
We build a proper-noun glossary for the whole bundle, translate every seal, and carry the certification chain through — send your documents for a pre-check in any language pair.
Durations are working-day estimates excluding agency queues, and are not a guarantee of any authority's decision.
Service steps at a glance and the documents you need first
A usable translation must mirror the source line by line, spell names exactly as in the passport, and follow the certification format the receiving party requires - a translator's certification, consular legalization in Thailand, or further certification at the destination mission. Confirm that format before translation starts.

Official sources & further reading
Statements on this page follow the authorities below. Confirm current requirements with the authority before filing. Last reviewed 2026-07-29.
Each page shows its last-reviewed date in the sources section. Authority requirements change, so confirm current conditions with the receiving authority before proceeding.
What is the fastest way to reach you?
Call or message on LINE during business hours for an initial route check, and send legible photos of the documents by email or LINE so the scope can be assessed accurately.
Where do I start if I am unsure which certification I need?
Start with three questions: which authority will receive the document, in which country, and by what date. Those answers determine the authentication route, the translation language and the full sequence.
Why are fees not published on the site?
Scope varies widely with document count, language and the consular steps involved, so we quote against the actual work and confirm details by phone, LINE or email before starting.
