What actually gets stamped
Nothing is written on the deed itself. The original stays where it was signed, bound into the notary's own archive, and it is never let out. What travels is a sealed copy: a fresh print, dated the day it is made, carrying a line that it matches the bound text. Every answer about how to apostille a Memorandum & Articles of Association follows from that.
Ask the notary for the copy they call autentica, meaning true to the original. Because it is dated on the day of printing, the folder copy from the year you started is of no use here. Once the sealed copy is in your hands you can apostille a Memorandum & Articles of Association in Bologna with no other body joining the chain.
The notary decides which court
A deed made in front of a notary is a notarial act, and those are stamped by the Procura della Repubblica, the prosecutor's office sitting at the court. It has to be the court for the district where the deed was signed, since that is the only place holding the notary's specimen signature. Papers from public offices go the other way, to the prefecture.
So read the front page of your deed and note who signed it and where. A firm that moved here later often finds its founding notary sat in another district, and the file then belongs to that other court. To apostille a Memorandum & Articles of Association in Italy you have to settle this single fact first.
When the by-laws have moved on
Companies rewrite their rules. A new share class, a new seat, a wider object clause: each of those was written up as its own deed, on its own date, by whichever notary was in the room. Ask the far office whether it wants the founding text plus the whole chain, or only the by-laws as they read today.
Then order what they name and nothing beyond it. A stamp goes on each deed, so a chain of five deeds means five stamped papers and a bundle nobody reads is money spent for nothing. The apostille cost for a Memorandum & Articles of Association in Bologna is a €16 tax stamp on each one, and some papers are let off it.
Reading a long Italian deed abroad
Deeds run long, and turning the words into another language is where the real time goes. Ask the reader abroad whether the whole text is wanted, or only the clauses on powers, capital and who may sign for the firm. Many registries name a short list of clauses and are content with a sworn version of just those.
Acceptance is their call and never ours. Whether they will take the legalisation of a Memorandum & Articles of Association in Bologna, and in what wording, is a matter for the desk that files it. Italy joined the Hague apostille club in 1978, so a member state needs no consulate step at all. Put the question to them in writing and keep the reply.
