A work permit for a company director — what should you know about notarial signature certification?

This question is specifically about “A work permit for a company director”, so it covers both the requirements attached to this document set and the order the steps must follow. Note who signed each certification and on what date for later reference. Record the reference number of each certification layer; it is the fastest way to trace status. Once the set is complete, check it line by line against the destination's own checklist before filing. The terms that frame this page are work · permit · company · director. The condition most often overlooked is that name spelling must match across every document in the set. The most frequent cause of delay in this group is missing supporting documents on the first submission. Before starting, confirm with the receiving body whether it wants an original, a certified copy or a certified translation, then check that names are spelled identically to the passport or ID card on every page, then verify the source document is still within any validity window the recipient applies. For documents going abroad, include international shipping time in the plan. With a fixed filing date, count backwards from it and book each certification step in reverse. Powers of attorney and declarations intended for use abroad are usually signed before a Notarial Services Attorney registered with the Lawyers Council of Thailand, then passed to the Department of Consular Affairs and the destination embassy for further legalisation. Thailand deposited its instrument of accession to the Apostille Convention on 30 June 2026, but the Convention is not yet in force for Thailand, so embassy and Department of Consular Affairs legalisation remains the working route. ILC handles the document side only — certified translation, notarial signature certification and legalisation runs at the Department of Consular Affairs or an embassy. ILC is not the deciding authority and cannot guarantee an approval. Cost and lead time depend on page count, language pair and the certification steps the receiving authority requires, so every file is quoted before work starts.
