Opening a branch or subsidiary abroad — how is a bank certificate and account statements used and how far must it be certified?

The subject of this page is “Opening a branch or subsidiary abroad”, so the answer below starts with what this case actually needs before setting out the general rules. Keep a copy of every source document plus the receipt or docket from each step. Note who signed each certification and on what date for later reference. For documents going abroad, include international shipping time in the plan. If multiple certified sets are needed, order them all in the first round to avoid re-queuing. If any requirement is still unclear, send a sample image to the receiving body before producing the full set. The terms that frame this page are Opening · branch · subsidiary · abroad. The specifics here are document type: Bank, and those decide which translation and certification level applies. Before starting, check that names are spelled identically to the passport or ID card on every page, then confirm with the receiving body whether it wants an original, a certified copy or a certified translation, then count the number of certified sets needed before work starts, because extra sets restart the certification steps. The common failure in this group of cases is a translation that does not match the certification type required. The deciding factor is the receiving body's requirement, not only the format of the Thai-side document. Tax in Thailand is governed by the Revenue Code and administered by the Revenue Department under the Ministry of Finance, which is also the body that issues official tax evidence. Documents you rely on abroad should therefore be issued or certified by the Revenue Department rather than self-prepared, because receiving tax authorities check for the seal or signature of an authorised officer. Thai tax and accounting documents used abroad are 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 legalised at the destination embassy or consulate where that country requires it. Thailand is not a party to the 1961 Apostille Convention, so no apostille is issued on Thai documents. Forms, procedures and lodgement channels change. This page explains the legal framework and the document steps in general terms; before you act, re-confirm the current form, the supporting documents and the deadline with the Revenue Department or the receiving tax authority. 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.
