Vehicle registration and import document certification — why files get rejected, and how to fix it
This page lists 9 rejection causes we see in practice for vehicle registration and import document certification, 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 @THAIL or call 064-2894888.
Causes and fixes
1. Chassis and engine numbers must match the registration book exactly.
Fix: Confirm this requirement with the receiving authority before work starts and record the answer in the case file.
2. Import approvals are tied to a specific vehicle and cannot be transferred.
Fix: Keep this as a checklist item on the front of the file and have a second reviewer sign it off before delivery.
3. Spell every name exactly as it appears in the passport, across every document in the same bundle.
Fix: Confirm this requirement with the receiving authority before work starts and record the answer in the case file.
4. Never remove staples or separate pages that an authority has bound and stamped across the seam.
Fix: Keep this as a checklist item on the front of the file and have a second reviewer sign it off before delivery.
5. Filing with an old extract issued long ago
Fix: Order a freshly issued original from the issuing authority and run the whole certification chain from that single copy.
6. Translating before confirming the accepted format
Fix: Confirm the certification route with the receiving authority in writing first, then translate once in that format.
7. Legalisation done, but the destination asks for one more layer
Fix: Check whether the destination country is an Apostille Convention member; if not, plan the destination-embassy step into the same schedule.
8. English spelling differs from the passport
Fix: Use the passport spelling across every document in the bundle and brief the translator before work starts.
9. Sending only the pages that look relevant
Fix: Scan and translate every page, including blank pages carrying stamps — authorities check the completeness of the set.
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.

An advisor, not only a document processor
Before any work starts, our team assesses how many certification layers your document actually needs, which authorities are involved, and the correct order for the office you will really file with. One step out of order usually means restarting the whole bundle. We work to recognise how each authority rejects files and prevent it up front.
- The certification route is matched to the receiving authority before work begins.
- Rejection risks are checked, from name spelling to document validity windows.
- The filing sequence is planned around the deadline you actually have.
