A foreign company opening a branch or representative office in Chonburi — where do you start?

The matter being asked about is “A foreign company opening a branch or representative office in Chonburi”, so it covers both the requirements attached to this document set and the order the steps must follow. Once the set is complete, check it line by line against the destination's own checklist before filing. Licensing turns on eligibility conditions that must be proved with that authority's own documents. A change of address or director usually has to be recorded on the licence too, not only in the company register. 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. Documents with a short validity window should be produced as close to the filing date as possible. Public holidays and embassy closures move certification queues more than most people expect. 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. What changes the timeline most here is whether the source documents are complete on day one. A key variable is the filing channel (in person, agent or online), which sets the copy format to prepare. The terms that frame this page are foreign · company · opening · branch. The specifics here are location: Chonburi, and those decide which translation and certification level applies. 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. 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. 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.
