A corporate power of attorney — what should you know about the translation and legalisation sequence for overseas use?

The point raised here is “A corporate power of attorney”, so it separates what is specific to this file from the standard certification chain. If multiple certified sets are needed, order them all in the first round to avoid re-queuing. When several certification layers are required, start with the slowest one. Attach a document index to the bundle so nothing is lost during review. Keep a copy of every source document plus the receipt or docket from each step. After filing, follow up on the cycle the office states rather than waiting past the deadline. The specifics here are document type: Poa, and those decide which translation and certification level applies. The terms that frame this page are corporate · power · attorney · know. The condition most often overlooked is that name spelling must match across every document in the set. The point to fix before starting is the real deadline, so the steps can be scheduled backwards from it. Before starting, count the number of certified sets needed before work starts, because extra sets restart the certification steps, then verify the source document is still within any validity window the recipient applies, then check that names are spelled identically to the passport or ID card on every page. A Thai corporate document for overseas use is normally translated into the language the destination requires, then legalised by the Legalisation Division, Department of Consular Affairs, Ministry of Foreign Affairs, and further legalised by the destination country's embassy or consulate where that country requires it. 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. Australian government agencies and financial institutions require non-English documents to be translated by a NAATI-certified translator showing the stamp and practitioner number; a corporate translation without the NAATI stamp is commonly rejected at the document-check stage. 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.
