Apostille vs. Embassy legalisation for Thailand
One route is short and one is long, and Thailand still uses the long one. Under consular legalisation an Italian authority confirms the signature on your paper, then Thailand's own mission in Italy confirms the Italian authority. Under the Convention a single certificate does both jobs at once. Because the treaty is not yet operational in Thailand, an apostille for Thailand travels with a consular stamp rather than instead of it.
Thailand's Hague status and what it means
Thailand's accession year is 2027 and the Convention enters into force there on 28 February 2027. That gap is long enough to matter: a student, a spouse or a company filing this year will finish the whole consular chain before the shortcut opens. An apostille from Italy to Thailand issued now is valid as an Italian act, but no Thai office is bound to act on it by itself.
The Bologna to Thailand route step by step
The chain has no shortcuts and each link needs the one before it. A certified original leaves the issuing office. The Prefettura or the Procura della Repubblica legalises the signature and the €16 tax stamp is applied per document. The package then reaches Thailand's embassy or consulate in Italy for the consular stamp. Only then is the paper ready for the office in Thailand that asked for it.
Cost and timing for this route
Costs split cleanly. The state side is the €16 marca da bollo on each document, with exemptions for some records; the consular side is the mission's own charge, and an official fee applies. Time is dominated by the consular stage, which runs on its own calendar rather than yours. Anyone with a fixed date in Thailand before 28 February 2027 is better off starting early and treating the Italian stamps as the quick part.
What Thailand asks of a Bologna file
Thai practice leans on the language and on the completeness of the bundle. Where the receiving body reads Thai, the sworn translation goes in before the stamps, not after. Company and university papers, the everyday output of Bologna, need the signature of an officer whose specimen the Italian office already holds, or the first desk cannot act. Meeting the apostille requirements for Thailand also means sending an intact original rather than a scan of one.
