Using a Thai legitimation registration when obtaining a passport or visa for a child after adoption — how should it be prepared?

This question is specifically about “Using a Thai legitimation registration when obtaining a passport or visa for a child after adoption”, so it separates what is specific to this file from the standard certification chain. The terms that frame this page are Using · Thai · legitimation · registration. The specifics here are document type: Legitimation, and those decide which translation and certification level applies. Before starting, verify the source document is still within any validity window the recipient applies, then count the number of certified sets needed before work starts, because extra sets restart the certification steps, then confirm with the receiving body whether it wants an original, a certified copy or a certified translation. What sets this case apart is the number of certified sets and the window in which they must be used. A key variable is the filing channel (in person, agent or online), which sets the copy format to prepare. Record the reference number of each certification layer; it is the fastest way to trace status. Attach a document index to the bundle so nothing is lost during review. Public holidays and embassy closures move certification queues more than most people expect. Plan the schedule with room for at least one review cycle at the receiving office. After certification, scan the full set before it leaves your hands. A Thai document filed with a foreign authority or court is translated in full — stamps, signatures and any text on the reverse included — then the translation is certified by the Legalisation Division of the Department of Consular Affairs, Ministry of Foreign Affairs, and afterwards by the destination country's embassy or consulate where that country requires it. Thailand is not a party to the 1961 Apostille Convention, so no apostille is issued on Thai documents. Confirm the accepted form of certification with the receiving body before work starts. The child's and the parents' names in the translation must match the passport spelling and agree across every document in the set — the single most common reason a file is returned. Where a name changed on marriage or divorce, or an older document romanised the name differently, attach the change-of-name evidence or a spelling statement so the documents visibly relate to one person. Dates of birth and ID numbers must also agree throughout. ILC provides document work and coordination only: translation, assembling the set, arranging signature certification, filing for legalisation and international despatch. ILC is not an adoption agency, not a Hague Central Authority, and guarantees no decision by any authority or court. Assessing applicants, matching a child and deciding parental power rest solely with the competent authorities and the courts. Cost and lead time depend on page count, target language, how many certified sets are required and the steps the receiving authority or court sets, so every file is quoted before work starts.
