Signatures come before any stamp
A contract between two firms is private paper. Nobody at a public desk knows your signature, so the chain cannot start until a notary confirms it. Learning how to legalize a signed commercial contract really means learning that order: the notary first, the state second, the consulate last.
Which Italian desk takes the file
Two offices share this work and they do not overlap. The Prefettura legalizes administrative paper; judicial and notarial acts belong to the Procura della Repubblica at the court. So the embassy legalization of a commercial contract in Naples can land at either counter, depending on how the notary handled your deal. Ask before you queue.
The mission signs last
After the Italian stamp comes the foreign one. The consular legalization of a commercial contract in Italy is a desk at the destination's embassy or consulate accepting the stamp beneath it and adding their own. Corporate windows are often narrow, so ask about the mission's opening days before you promise a signing date to the other side.
Cost and the clock
Money splits in two. To legalize a commercial contract in Naples you buy a €16 marca da bollo for the Italian file. The mission then adds a fee of its own, which it alone sets. Timing runs 10–15 business days as standard and 3–5 on the express route. Several copies made in one batch cost you less in time than in fees.
Who asks for a stamped deal
Tender boards, customs brokers, lenders and distributors all ask for stamped copies of the deal behind a payment. The embassy attestation of a commercial contract in Naples is what lets such an office put your paper on its own record. Order one stamped copy per office from the start; a single spare is far cheaper than a repeat run.
Binding and wording
Keep the bundle sewn and numbered. Consular desks refuse loose sheets, and a contract with unnumbered annexes invites a clerk to ask what is missing. The facts here do not fix a target language, so confirm the required language with the receiving office in writing before anything is turned over. Bind the translation to the stamped original, never after.
What goes wrong most often
Three snags account for nearly every delay. One is a signer who is not authorized for the company. Another is an annex named in the text but missing from the bundle. The third is a country that never needed the consular leg at all. Whether that last stamp applies rests on the destination; confirm with the receiving authority before you pay a consular fee.
