Certified translation of a Thai FDA licence or registration number for a business in Ayutthaya — how does it work?

This question is specifically about “Certified translation of a Thai FDA licence or registration number for a business in Ayutthaya”, so it deals with the case-specific points first and the shared rules afterwards. The specifics here are document type: Fda; location: Ayutthaya, and those decide which translation and certification level applies. The terms that frame this page are Certified · translation · Thai · licence. The point to fix before starting is the real deadline, so the steps can be scheduled backwards from it. The most frequent cause of delay in this group is missing supporting documents on the first submission. Before starting, verify the source document is still within any validity window the recipient applies, then count the number of certified sets needed before work starts, because extra sets restart the certification steps, then confirm with the receiving body whether it wants an original, a certified copy or a certified translation. Leave buffer time in case a translation has to be amended or a source document re-issued. With a fixed filing date, count backwards from it and book each certification step in reverse. Keep a copy of every source document plus the receipt or docket from each step. If the receiving body confirmed its requirements by email, keep that message with the file. A change of address or director usually has to be recorded on the licence too, not only in the company register. Most licences carry an expiry date, so plan renewal ahead of the deadline. After certification, scan the full set before it leaves your hands. A Thai corporate document used overseas is normally translated in full — including seals and signatures — then the translation is certified by the Legalisation Division, Department of Consular Affairs, Ministry of Foreign Affairs, and finally by the destination country's embassy or consulate where that country requires it. Thailand is not a party to the 1961 Apostille Convention, so no apostille is issued for Thai documents. Company formation in Thailand runs under the Civil and Commercial Code for partnerships and private limited companies, and the Public Limited Companies Act B.E. 2535 for public companies. The registrar is the Department of Business Development (DBD) at the Ministry of Commerce, which issues the company affidavit. When a foreign counterparty or authority asks for proof of existence, use the registrar-issued affidavit rather than a copy the company printed itself. ILC handles the document side: translation, certification of the translation, assembling the set against the authority's checklist, and coordinating the MFA and embassy steps. ILC is not counsel of record for a licence application, gives no legal ruling, and cannot guarantee how a licensing authority will decide. Cost and lead time depend on page count, target language, how many certified sets are required and the steps the receiving authority sets, so every file is quoted before work starts.
