What the paper has to show
A Certificate of Incumbency names the people who run a company and says what they may sign. Italy has no form of its own with that title. So a reader abroad is usually served by the extract from the Registro delle Imprese, the business register kept at the Chamber of Commerce, which lists the firm, its officers and their powers.
Some readers want more than the register can show, such as a line naming who signed one deal. Then your legal representative signs a short statement in front of a notary, who checks the identity and seals the page. Which version you pick decides the counter you go to next, so ask the office abroad before you order. That one question saves the most time.
Two counters, one city
A register extract is an administrative paper, so the Prefettura, the state office for the province, adds the stamp. A statement sworn in front of a notary is a notarial act, and those belong to the Procura della Repubblica at the court. Knowing how to apostille a Certificate of Incumbency is mostly knowing which of those two your paper is.
The counter follows the signature. To apostille a Certificate of Incumbency in Genoa the extract has to come from the register office for that province, or the notary has to be one whose acts the local court holds on file. A firm with its seat here but a notary elsewhere splits the job across two provinces.
Fee, and how much time to allow
The apostille cost for a Certificate of Incumbency in Genoa is a €16 tax stamp per document, and some documents are exempt. The register charges its own counter fee for the extract, which that office sets. Allow time for both queues, because the paper has to exist before anyone can stamp it. Deals slip when a firm books the stamp before it holds the page.
Who asks for this page
Banks abroad ask for it before they open an account for an Italian firm. So do foreign registries when you set up a branch, buyers who want to know your signatory is real, and public bodies running a tender. Italy has been inside the Hague Apostille Convention since 1978, so its member states take the single stamp and ask for nothing further.
Language, and paper that goes stale
An officer list ages fast. If a director steps down or a power is cut, the stamped page still shows the old picture, and a bank will see that at once. Pull the extract near the day you file, and tell us if a change is pending. The legalisation of a Certificate of Incumbency in Genoa for a country outside the Hague list adds consular steps, so settle the route early.
The rules to apostille a Certificate of Incumbency in Italy hold in every province, yet the reading side abroad sets the format. Most take the Italian page with a translation attached, and some want that translation sworn before a Tribunale, an Italian court. Ask them in writing which they accept, then order the translation once.
