Certified Translation — Confirm the Signer and Required Format
Start with the receiving authority’s instructions to distinguish translation certification, copy certification, signature witnessing and legalisation. Certified and sworn translations are not universally interchangeable. Request a quotation after document review.
Service illustration; not evidence of certification of a particular document.
Start with the real document and recipient instructions, not the number of seals or a worldwide acceptance claim. Keep written format confirmation before commissioning to avoid unnecessary steps.
Checks before commissioning
Certified does not automatically mean sworn
Some recipients require a translator appointed or sworn under their own jurisdiction. A Thai translation with MFA or embassy authentication is not automatically equivalent. For Germany, ask the actual recipient whether a beeidigt or otherwise specified translator is required before choosing the route.
Translation, certification and legalisation are different
A translation certificate identifies the translator, language direction, date and accuracy statement. Notarial witnessing or copy certification is a separate act. Legalisation authenticates a signature or seal within the authority’s remit; it does not validate every statement or guarantee recipient acceptance. Do not add every layer to every document by default.
Apostille: check the date and both jurisdictions
Thailand acceded on 30 June 2026; the Convention enters into force for Thailand on 28 February 2027. Before that date, confirm the legalisation route actually available. Afterwards, check treaty relations, eligible documents, exceptions and competent authorities in the HCCH status table. An Apostille does not replace recipient-specific translator requirements.
China, India, Saudi Arabia and Vietnam are parties, not non-party examples. For the UAE, check a non-Apostille route with the recipient. Country membership alone does not determine every translation or authentication step.
Verify the assigned practitioner
An attorney credential is not a NAATI translator credential, and association membership is not translator certification. Verify the assigned individual, language direction, credential status and recipient rules. Do not assume an agency is NAATI-certified or has sworn translators for every language.
Review the complete source document
Include every page, reverse side, seal, note and attachment without clipping.
Match names to the passport and disclose former names or discrepancies.
Ask whether the recipient requires originals, issuer-certified copies, notarised copies or electronic files.
Check source-document age against the actual application; there is no universal three- or six-month rule.
Written scope and delivery confirmation
Quotation on request via staff. Supply the language pair, page count, purpose and recipient instructions. Timing is confirmed after document review, practitioner availability and agency appointments; no same-day or fixed-day promise applies. Thai Consular Affairs legalisation government fees are THB 200 normal / THB 400 express per legalisation sticker, separate from our quoted service. These are not an advance announcement of Apostille fees.
Privacy, corrections and application outcomes
Provide only necessary data and ask about access, transmission, overseas translators and retention or deletion terms before commissioning. Do not infer ISO certification, HSM storage, insurance or a seven- or ten-year retention period. Report an error with the relevant source page for review under the written agreement. Refunds and compensation must be confirmed in that agreement. The receiving authority decides acceptance and visa outcomes; translation does not guarantee approval.

Frequently asked questions
Are notary and MFA legalisation always required?
No. Obtain the receiving authority’s required certification and sequence. Notarial certification does not replace translator credentials or guarantee acceptance.
Is NAATI equivalent to ATA or ITI membership?
These are different systems. Verify the assigned translator or interpreter credential and language direction. Association membership alone does not establish recipient acceptance.
When can the Apostille Convention apply to Thailand?
It enters into force for Thailand on 28 February 2027. Treaty relations, eligible document types and competent authorities still need checking; not every document qualifies.
Can a scan replace the original?
A clear scan can support an initial translation assessment. Filing and authentication may require an original or a specified certified copy; obtain recipient confirmation first.
When does a translation expire?
There is no single expiry rule for all translations. A recipient may impose source-document age, certification-date or current-information requirements for the specific application.
What are your fees and delivery times?
Quotation on request via staff. Timing is confirmed after document review, language pair, practitioner availability and agency appointments; no fixed turnaround is guaranteed.
Can AI output simply be signed as a certified translation?
Do not certify unchecked text. The translator must compare it with the complete source and take responsibility under recipient rules. Tool use alone does not establish automatic acceptance or rejection.
What if the recipient rejects the document?
Obtain the written reason and send it with the source and translation. Review whether wording, practitioner credentials or authentication need changing. Corrections and refunds follow the written agreement; acceptance is not guaranteed.
Does Germany require a sworn translator?
Ask the receiving German authority. An MFA plus embassy chain is not automatically equivalent to a beeidigte Übersetzer.
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.
Names or places spelled inconsistently across the bundle
Underlying cause
Documents were translated separately without a shared glossary
Prevent before filing
Fix one spelling standard from the passport and civil registry
How to fix a rejection
Reissue the whole set with consistent spelling
Estimated time cost
Adds roughly 1–4 working days (estimate)
Seals and signatures were not rendered
Underlying cause
The translator skipped non-body elements
Prevent before filing
Require every element to be described, including marginal text
How to fix a rejection
Add seal and signature descriptions and reissue
Estimated time cost
Adds roughly 1–3 working days (estimate)
Dates off by 543 years
Underlying cause
Buddhist-era conversion error or unannotated retention
Prevent before filing
State the calendar explicitly and re-check every date
How to fix a rejection
Correct and reissue with a conversion note
Estimated time cost
Adds roughly 1–2 working days (estimate)
Translator certification wording not accepted
Underlying cause
Each recipient prescribes different wording and translator details
Prevent before filing
Request the recipient's certification statement template first
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.
How the work runs

Documents to prepare first
• Clear originals or scans of every page, including reverse-side seals
• Passport bio page for the authoritative spelling of names
• Name-change records where older documents differ
• Any format requirements issued by the receiving party
• Current company affidavit and objectives
• Complete financial statements or contracts with all annexes
If you would rather not risk a rejection over small details, our team handles requirement checks, translation, review and legalization end to end - talk to us before you start.

Documents used abroad must pass the correct certification chain before submission.
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.
