A private paper needs a public mark
A commercial contract is a private paper. Two firms sign it and no official has been near it, so no desk will stamp it as it stands. An apostille is one stamp that proves an official signature is real, so the file must first carry such a signature. In practice a notary certifies the signatures. Only then can you apostille a commercial contract in Catania.
Prefettura or Procura?
The desk depends on the shape your file ends up in. Plain state papers go to the Prefettura, the prefect's local branch of the government. Anything a notary or a judge drew up goes to the Procura della Repubblica, the prosecutor's office at the court. We read your file first and take it to the right one, because the wrong queue wastes a day.
Before you plan how to apostille a commercial contract, get the order of steps right. Every party signs in front of the notary, on the same version, with the schedules attached and initialled. Nothing may be added later. A page slipped in after the seal breaks the link, and the desk hands the bundle straight back.
Fee, copies and timing
The state fee is a tax stamp of €16 per document, and some papers are exempt. The apostille cost for a commercial contract in Catania follows the count of documents, not of pages. A long deal costs no more than a short one. The notary charges apart from that for taking the signatures. No desk promises a fixed wait, so build slack into your closing date.
Distributors, tenders and disputes
Firms send a stamped deal abroad to sign up a dealer, to join a tender, to start a joint venture, or to put the contract before a foreign court. Lenders ask for it when the deal backs a loan. Italy has been in the Hague Convention since 1978, so a member state takes the stamp on trust. You can apostille a commercial contract in Italy even when the work happens elsewhere.
Which version rules
If the deal runs in two languages, say plainly in the text which version rules, then stamp that one. A translation made later is a separate paper and carries no weight on its own. Where the other country sits outside the Hague Convention, full legalisation of a commercial contract in Catania applies, ending at its consulate.
