A foreign investor setting up a Thai company in Chonburi — where do you start?

What the enquirer needs to know is “A foreign investor setting up a Thai company in Chonburi”, so it flags what usually causes documents like this to be rejected before summarising the general practice. After filing, follow up on the cycle the office states rather than waiting past the deadline. 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. Documents with a short validity window should be produced as close to the filing date as possible. With a fixed filing date, count backwards from it and book each certification step in reverse. Most licences carry an expiry date, so plan renewal ahead of the deadline. A change of address or director usually has to be recorded on the licence too, not only in the company register. The terms that frame this page are foreign · investor · setting · Thai. The specifics here are location: Chonburi, and those decide which translation and certification level applies. Before starting, make sure document numbers, issue dates and issuing-office names match across the set, then keep a digital copy of every page, including seals and signatures, then plan the timeline so certification finishes before the real filing deadline. The deciding factor is the receiving body's requirement, not only the format of the Thai-side document. A key variable is the filing channel (in person, agent or online), which sets the copy format to prepare. 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.
