Working for a foundation or non-profit organisation — what should you know about notarial signature certification?

This question is specifically about “Working for a foundation or non-profit organisation”, so it covers both the requirements attached to this document set and the order the steps must follow. Public holidays and embassy closures move certification queues more than most people expect. For documents going abroad, include international shipping time in the plan. Before starting, ask in advance which category of certified translator the destination accepts, then plan the timeline so certification finishes before the real filing deadline, then keep a digital copy of every page, including seals and signatures. Check first whether the issuing office of the source document is one the destination recognises. The deciding factor is the receiving body's requirement, not only the format of the Thai-side document. The terms that frame this page are Working · foundation · non-profit · organisation. If any requirement is still unclear, send a sample image to the receiving body before producing the full set. If the receiving body confirmed its requirements by email, keep that message with the file. Note who signed each certification and on what date for later reference. 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. ILC handles the document side only — certified translation, notarial signature certification and legalisation runs at the Department of Consular Affairs or an embassy. ILC is not the deciding authority and cannot guarantee an approval. 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.
