Certified translation in every language pair — why files get rejected, and how to fix it
This page lists 8 rejection causes we see in practice for certified translation in every language pair, each with a fix that can be applied before filing. Most are caught during document review, well before the cost of re-certifying an entire set — to have our team review your scans first, contact LINE @Thainotary or call 094-8958999.

Causes and fixes
1. Confirm which body certifies the translation before work begins; requirements differ by destination.
Fix: Keep colour scans of the reviewed set so you can compare quickly if the destination asks for a targeted correction.
2. Keep one glossary per case so names and titles never drift between documents.
Fix: Check this during the document review, before certification — fixing a source document costs far less than re-certifying the set.
3. Spell every name exactly as it appears in the passport, across every document in the same bundle.
Fix: Keep colour scans of the reviewed set so you can compare quickly if the destination asks for a targeted correction.
4. Never remove staples or separate pages that an authority has bound and stamped across the seam.
Fix: Check this during the document review, before certification — fixing a source document costs far less than re-certifying the set.
5. The intended use is never stated up front
Fix: State the receiving authority and the purpose before work begins so the correct level of certification is chosen the first time.
6. Signing in advance and only then looking for a certifier
Fix: Sign in front of the certifying officer as the procedure requires, never beforehand.
7. Incomplete scans sent for the initial review
Fix: Send every page for review first, then produce the final certified set.
8. Using a superseded form
Fix: Check the authority's current form before filling it in and note the date you checked in the file.

A review before filing costs less than re-certifying
Most rejections are not about the content of the document — they come from steps taken in the wrong order, or a format the receiving authority does not accept. Send us the scans before work starts and we will confirm the correct certification route and the full document list first.

Handled by a team with more than 15 years of experience.

How the process runs — Certified translation in every language pair
- State the purpose and the receiving authority so the correct level of certification is chosen.
- Send scans of every page so completeness can be checked before work starts.
- Prepare the translation or the instrument in the format the receiving authority requires.
- Sign or certify before the officer authorised by law to witness that document type.
- Collect the finished set and keep a copy for the next filing.
Fees and processing times are set by each authority and vary by document and destination — confirm them with the responsible agency.
Handling it yourself vs letting iLC run it
| Aspect | Doing it yourself | With iLC |
|---|---|---|
| Working out which steps apply | You read each authority's rules yourself, and usually learn a step was missing only after the bundle is refused. | Our advisers review the documents before work starts and sequence translation, notarisation, MFA, and embassy in one pass. |
| Time spent filing | Repeat trips to each office, queueing and collecting in person. | We file on your behalf; you send scans and receive the finished set by post or courier. |
| Risk that the translation is refused | Agency names, job titles, and the certification wording often do not match what the receiving office accepts. | We use terminology and certificate formats the receiving authority has accepted before, with two-stage proof-reading. |
| If the bundle is rejected | You diagnose the cause and refile yourself, losing a full cycle. | We identify the cause, correct it, and refile without you starting over, with progress reported along the way. |
