A certificate confirming the company is active — what should you know about using a foreign corporate document inside Thailand?

The matter being asked about is “A certificate confirming the company is active”, so it covers both the requirements attached to this document set and the order the steps must follow. If any requirement is still unclear, send a sample image to the receiving body before producing the full set. High-resolution photos of seals and signatures help when the destination asks for re-verification. Keep a copy of every source document plus the receipt or docket from each step. With a fixed filing date, count backwards from it and book each certification step in reverse. For documents going abroad, include international shipping time in the plan. 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. The biggest risk in cases like this is doing the certification steps out of order, which forces a restart. The most frequent cause of delay in this group is missing supporting documents on the first submission. The terms that frame this page are certificate · confirming · company · active. The specifics here are document type: Goodstanding, and those decide which translation and certification level applies. A corporate document issued abroad for use with a Thai authority — a parent-company certificate or a shareholders' resolution, for example — is normally legalised in the country of origin and by the Royal Thai Embassy there, then translated into Thai and certified by the Department of Consular Affairs before it is filed with the DBD or the relevant agency. Thailand deposited its instrument of accession to the Hague Apostille Convention on 30 June 2026, but the Convention is not yet in force for Thailand, so consular legalisation through the Ministry of Foreign Affairs and the relevant embassy remains the working route; confirm the current requirement with the destination before filing. Foreign participation in business in Thailand falls under the Foreign Business Act B.E. 2542, which sets out restricted business lists, while investment promotion is administered by the Board of Investment under the Investment Promotion Act B.E. 2520 as amended; the document set to be translated differs according to the route used. ILC handles document work only — translation, certification of the translation, notarial signature certification and the legalisation run at the Ministry of Foreign Affairs and embassies. ILC is not a registrar, auditor or tax adviser and cannot guarantee the decision of any authority or counterparty. Cost and lead time depend on page count, the language pair and the certification steps the destination requires, so every file is quoted before work starts.
