An investor from Australia setting up a representative office — how should the supporting documents be translated and certified?

What the enquirer needs to know is “An investor from Australia setting up a representative office”, so the answer below starts with what this case actually needs before setting out the general rules. The next step is confirming the filing channel and the copy or file format required. Attach a document index to the bundle so nothing is lost during review. Note who signed each certification and on what date for later reference. Leave buffer time in case a translation has to be amended or a source document re-issued. Documents with a short validity window should be produced as close to the filing date as possible. 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. Check first whether the issuing office of the source document is one the destination recognises. What sets this case apart is the number of certified sets and the window in which they must be used. The terms that frame this page are investor · Australia · setting · representative. The specifics here are destination: Au, and those decide which translation and certification level applies. Foreign documents used in a work permit or incorporation file — degrees, experience letters, the parent company's certificate of incorporation, powers of attorney and passports — must be translated into Thai or English as the office requires and certified along the correct chain: certification in the country of origin, then embassy or Department of Consular Affairs legalisation as applicable. Companies are registered with the Department of Business Development (DBD), Ministry of Commerce: a private limited company is formed under the Civil and Commercial Code and a public limited company under the Public Limited Companies Act B.E. 2535 (1992), with a memorandum of association, articles and a shareholder list among the incorporation papers. Thailand deposited its instrument of accession to the Apostille Convention on 30 June 2026, but the Convention is not yet in force for Thailand, so embassy and Department of Consular Affairs legalisation remains the working route. Cost and lead time depend on page count, language pair and the certification steps the receiving authority requires, so every file is quoted before work starts.
