Need your documents reviewed or your case assessed? Ask our team by phone, LINE, or email. We reply during business hours (Mon–Fri 9:00–18:00, Sat 9:00–15:00, ICT).

Before translating anything, identify the certification system the receiving authority accepts: NAATI (Australia), sworn translators (Germany, France, Spain, Italy), certified translation with a Certificate of Accuracy (US/UK), or a Ministry of Justice registered translator for Thai courts.
Prefer not to handle the queues yourself, or worried about a rejection? Send us photos of your documents for a free pre-check. We handle the full chain — obtaining certified copies, translation, certification and submission — and keep you updated at each step. Reach us on LINE, phone or email during business hours.
"Certified translation" does not mean the same thing everywhere — each receiving body accepts a different format.
| Route | When to use | Certifying authority | Approx. duration | Rejection risk |
|---|---|---|---|---|
| Translator's certification + consular legalisation | Thai documents going to a foreign authority via its embassy | Department of Consular Affairs, MFA Thailand | Variable, depending on queue and submission channel | A layout that does not match the consular template is refused at the counter |
| Translation by an accredited/sworn translator abroad (NAATI, sworn translator) | Destination is Australia or a sworn-translator jurisdiction | That country's accreditation body, e.g. NAATI | Variable, usually a few working days | Using a translator whose accreditation lapsed, or a translation without the stamp/registration number |
| Translation certified by a notarial services attorney | The receiving party is private — a university, employer or overseas bank | Attorney licensed by the Lawyers Council of Thailand | Usually same day to a few days | Many foreign government bodies will not accept this in place of consular legalisation |
Timelines above are practical estimates from live casework and can change with each authority's policy; confirm with the receiving authority before booking travel. If you would rather not test routes by trial and error, our advisers can assess which route fits your case.
Our team has worked on cross-border documents, certified translation and government liaison for over 15 years. Most rejections we see are not caused by missing paperwork but by choosing the wrong route on day one, so we always start with a case assessment.
We look at your destination, purpose and deadline, then tell you which certification route applies — and which steps you can skip.
Name spelling, consistency across documents, document age and translation format are checked before anything reaches a counter.
We sequence the steps around your appointment or travel date and flag bottlenecks in advance.
We read the refusal reasons, identify the underlying cause, and plan a resubmission that answers what the authority asked for.
Rather not learn by trial and error? Send your case details and document photos for a review — reach us on LINE, phone or email during business hours.
When translation, certification and apostille or embassy steps are chained, allow for each authority's queue and start with the longest step so the underlying original does not age out.
Many civil-registry and court documents are only accepted if issued recently. Request a newly certified copy before translation rather than reusing an old photocopy.
Certification systems are not interchangeable. Australian authorities require NAATI-certified translators, while documents used inside Thailand or filed at embassies in Thailand usually need translation certification by the Department of Consular Affairs. Tell us the receiving authority and country first.
Translations must reproduce the given name and surname exactly as printed in the passport you will submit, not a fresh transliteration. Always send the passport bio page together with the documents.
A consular-certified Thai translation does not replace a NAATI translation for Australian authorities, and a NAATI stamp is not a Thai government certification. Choose the system that matches the destination from the start.
Many authorities require the source document to be attached to each translated page so the text can be verified. A standalone translation is usually returned.
If you have changed your name or used different spellings, include the official name-change certificate and its translation; otherwise the authority may treat the documents as belonging to different people.
Seals, signatures, reverse-side text and marginal notes must all be rendered or described. Omitting them is one of the most common rejection causes.
Requirements differ by authority and destination country and can change. Confirm current conditions with the receiving authority, or ask our team by phone, LINE or email.
These topics reflect the rules and practice of the relevant authorities and can change. Confirm with the receiving authority, or ask our team by phone, LINE or email.
