An institutional conduct reference — what should you know about Thailand's apostille status?

What the enquirer needs to know is “An institutional conduct reference”, so the answer below starts with what this case actually needs before setting out the general rules. If the receiving body confirmed its requirements by email, keep that message with the file. Keep a copy of every source document plus the receipt or docket from each step. When several certification layers are required, start with the slowest one. For documents going abroad, include international shipping time in the plan. If the name on the record differs from the current name, attach the change-of-name evidence. Education files normally pair a transcript with a qualification certificate, and institutions check both together. The terms that frame this page are institutional · conduct · reference · know. The specifics here are document type: Conduct, and those decide which translation and certification level applies. Before starting, confirm with the receiving body whether it wants an original, a certified copy or a certified translation, then check that names are spelled identically to the passport or ID card on every page, then verify the source document is still within any validity window the recipient applies. The deciding factor is the receiving body's requirement, not only the format of the Thai-side document. The biggest risk in cases like this is doing the certification steps out of order, which forces a restart. Once the set is complete, check it line by line against the destination's own checklist before filing. 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; always confirm the current requirement with the receiving authority before filing. A Thai educational document intended for overseas use is normally translated into the language the destination requires, then legalised by the Legalisation Division of the Department of Consular Affairs, Ministry of Foreign Affairs, and where the destination requires it, further legalised by that country's embassy or consulate. 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 an educational institution or a credential-evaluation body and cannot guarantee recognition or admission. 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.
