Which company paper the court will stamp
An apostille is a single certificate that proves a seal or signature on your paper is genuine. Your founding deed was signed in front of a notaio, which makes it a notarial act. People ask how to apostille an Articles of Incorporation when the original never leaves the notary's file, and the answer is that a certified copy carries the seal instead.
That is also why you can apostille an Articles of Incorporation in Italy only at the court in whose district the deed was drawn up. A deed signed in Bari sits with the Bari court. Amendments signed later in Milan or Rome belong to those courts, even when the company trades from one address.
Getting a copy the desk can accept
To apostille an Articles of Incorporation in Bari you need a copia conforme, a copy the notary marks as true to the original. Old photocopies in the company binder will not do, because the seal must be one the court can trace to a signature on its list. A fresh copy costs the notary's own charge and saves a second trip.
The tax stamp and what it covers
The apostille cost for an Articles of Incorporation in Bari is the same public charge as any other act. It is a €16 tax stamp per document, and some papers are exempt. Nobody at the desk can raise or drop it. What you cannot pin down in advance is the wait, since the queue depends on the week you walk in.
What a stamped deed opens abroad
Banks ask for it before they open an account for an Italian company. Tender boards, buyers and foreign registries ask for it when they set up a branch, sign a supply deal or check who may sign for the firm. Lenders often want the deed and a recent extract together, so read the request line by line.
You may see the request written as the legalisation of an Articles of Incorporation in Bari. That is the older name for the job. Italy has been in the Hague Convention of 1961 since 1978, so member states take the single apostille. Whether your destination is one of them is a question for the receiving desk.
Language and the last checks
The stamp proves the seal, not the meaning of a single clause. A registry that works in one language will still ask for a sworn translation, made by a translator who signs an asseverazione, a formal statement of accuracy, in court. Ask whether they want the share capital clause on its own or the whole deed rendered.
