Must a power of attorney for overseas use be notarised?

The matter being asked about is “Must a power of attorney for overseas use be notarised”, so it flags what usually causes documents like this to be rejected before summarising the general practice. 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. The terms that frame this page are power · attorney · overseas · notarised. For documents going abroad, include international shipping time in the plan. With a fixed filing date, count backwards from it and book each certification step in reverse. 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 next step is confirming the filing channel and the copy or file format required. Keep a copy of every source document plus the receipt or docket from each step. High-resolution photos of seals and signatures help when the destination asks for re-verification. Powers of attorney and declarations intended for use abroad are usually signed before a Notarial Services Attorney registered with the Lawyers Council of Thailand, then passed to the Department of Consular Affairs and the destination embassy for further legalisation. 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.
