Pre-filing check: You check against the authority's own checklist / Checked by a team that has seen how that office rejects files · Travel: You attend within the office's service hours / The team files and follows up on your behalf · If it is rejected: You correct and refile yourself / Corrected and refiled under the agreed engagement terms · Choosing the certification level: You read the regulations and decide / The route is assessed against the receiving authority before work starts · Record keeping: You keep your own copies / A digital copy set is handed over for the next filing · Best suited to: A single document with no hard deadline / Multiple documents, multiple authorities, or a fixed filing date

Which route should I choose?

If the deadline cannot slip, review the route with the team before starting. · In multi-authority work, one step out of order usually means restarting the whole bundle.

What documents are needed for certified translation in every language pair?

Original document plus one clear copy of every page · Copy of the passport or Thai national ID card of the signatory · Written statement of the purpose and the receiving authority · Supporting records the receiving authority lists in its own checklist · Power of attorney if the signatory cannot attend in person · Contact details for follow-up questions from the receiving authority

Can iLC handle the whole process?

Yes — document review, translation, certification in the correct order, and filing with each authority. LINE @THAIL · +66 92-017-0000 · Contact@thailaw-accounting.co.th

Can this be done from outside Thailand?

Yes. Scans are reviewed first, the certification route is confirmed, and the finished set is delivered digitally or couriered.

What happens if the wrong route is used?

The file is usually rejected and the whole set has to start again, so the receiving authority's requirements should be confirmed before any work begins.

Support continues after delivery

Document work rarely ends with one submission: the receiving authority may request more, or you may need to file again next year. We keep a digital copy set and a record of the certification route used for every job, so the next round starts from the right point, and you can consult us when the destination changes its requirements. Handled by a team with more than 15 years of experience.

The certification route of each job is recorded for the next round.
Guidance when the destination requests additional documents later.
New document sets checked for consistency with what you already filed.
