A fit-to-fly medical certificate — what should you know about using foreign medical documents in Thailand?

The scope of this answer is “A fit-to-fly medical certificate”, so it covers both the requirements attached to this document set and the order the steps must follow. The specifics here are document type: Fittofly, and those decide which translation and certification level applies. The terms that frame this page are fit-to-fly · medical · certificate · know. Check first whether the issuing office of the source document is one the destination recognises. The condition most often overlooked is that name spelling must match across every document in the set. 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. 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. 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. Once the set is complete, check it line by line against the destination's own checklist before filing. A medical document issued abroad for use with a Thai authority generally has to be certified in the country of origin and by the Royal Thai Embassy or Consulate there, then translated into Thai with the translation certified by the Department of Consular Affairs before filing. Requirements should be confirmed with the receiving office each time, as they vary by matter. A Thai-issued medical document intended for a foreign authority normally follows this order: obtain the original from the facility, have it translated by a translator the destination accepts, certify the translation at the Legalisation Division, Department of Consular Affairs, Ministry of Foreign Affairs, then obtain the destination embassy's attestation where required. Each step verifies only what falls within its own authority. A medical translation must preserve the diagnosis, disease codes, drug names, dosages, units and result values exactly as written — no rounding, no unit conversion, no summarising. Where the original is illegible handwriting, the facility should be asked for a typed version or a written confirmation rather than the meaning being guessed. 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 medical facility or an insurer, gives no clinical advice, and cannot guarantee any authority's decision. Cost and lead time depend on page count, the density of clinical terminology, the target language and the certification steps required, so every file is quoted before work starts.
