Which Italian desk your paper goes to
Italy splits this work between two offices, and the paper decides which one. The Prefettura is the state's office in each province, and it legalises records from town halls, schools, police offices and other public bodies. The Procura della Repubblica sits at the courthouse and takes court papers, along with anything drawn up by a notary. Getting that choice right at the start saves the most time on the whole route.
Vietnam's Hague status and what it means
Vietnam has joined the Hague Apostille Convention, and the treaty enters into force there on 11 September 2026. Before that day an apostille is not yet accepted for Vietnam, so document legalisation for Vietnam still runs through the mission in Italy. From 11 September 2026 an apostille from Italy to Vietnam replaces that consular step, and the file ends its journey in Italy.
The Messina to Vietnam route step by step
Gather the originals before anything else, and keep them together in one envelope. The desks work per document, so a batch keeps the fees, the trips and the waiting in one place. Once the Italian stamp and the €16 tax stamp are on, the file moves to the mission for the consular stamp, and then the whole bundle comes back to you.
Cost and timing on this route
Italy's part has a fixed price: a €16 tax stamp per document, with exemptions for some kinds of record. The mission charges its own fee, set at that end rather than in Italy, so leave room for an official fee there. Timing is the looser part, and it turns on the desk, the season and how complete your bundle is when it lands.
The apostille requirements for Vietnam after the change add nothing to the Italian side, so the money and the time you spend there buy you the same stamp either way. What the change takes out is the last leg of the journey, and with it the wait at the mission.
