A university award, not a school-leaving paper
People who ask how to legalize a Degree Certificate mean the award a university gave them at the end of a course. It is not the leaving certificate a secondary school hands out at the close of its cycle. The two papers come from different bodies and prove different things.
So read the request from abroad closely. A licence body asking for proof of a degree will not take a school paper, and an admissions office that asks for both wants two separate bundles. Settle which it is before you order a thing from the registrar.
Parchment or registrar's certificate
The embassy legalization of a Degree Certificate in Venice is normally done on the registrar's certificate, not on the parchment. The pergamena hangs on a wall and cannot be replaced if it is lost in the post. The registrar's sheet states the same award and can be printed again.
Ask the student office for the version showing the award, the date and, where the reader wants them, the marks. Say plainly that it is going abroad. The clerk will then issue a sheet with a signature and a stamp on it rather than a plain printout.
A signature the state can check
The consular legalization of a Degree Certificate in Italy goes through the Prefettura, the government office in each province that legalises administrative papers. Its clerk matches the signature on your certificate against a specimen held on file. That is the whole of the check at this counter.
So the signature has to be one the office can trace. A certificate signed by a state university registrar usually is. If your university is a private body, ask the registrar which route they use for papers going abroad, because a further step may come first.
What it costs and how many days
The Italian charge is a €16 tax stamp (marca da bollo), fixed to the file before it is lodged. The consulate then takes a consular fee of its own, at a tariff that mission sets alone. Ask them for the figure in writing so that nobody is left guessing.
The full run takes 10–15 business days, dropping to 3–5 business days where the mission offers an express lane. The registrar's own wait sits in front of that, and in some offices it is the longest part of all. Order the certificate first and the rest follows.
Licences, jobs and postgraduate places
Graduates legalize a Degree Certificate in Venice to sit a licence exam abroad, to earn points on a work visa, or to win a place on a postgraduate course. Employers ask as well, especially where a pay grade is tied to a qualification on file.
Each of those readers checks a different thing. A licence body cares about the subject and the hours. A visa desk cares about the level. An admissions office cares about the marks. Ask which detail matters, because that decides whether the marks must be printed on the sheet.
Transcripts, wording and acceptance
A transcript of records is a separate paper and needs its own stamps. It lists the exams and the marks course by course, while the certificate simply states the award. Many admissions offices want the pair, and each one travels the chain on its own.
Order the embassy attestation of a Degree Certificate in Venice only when the destination has confirmed that step. Whether consular legalisation is required depends on the destination country, so ask the receiving authority in writing and keep the reply on file. Some destinations take a single-step certification.
Then settle the wording. Confirm the required language with the receiving office in writing. We will have the text sworn before a Tribunale in Italy so the marks and the course title read as the university wrote them. A loose rendering of a course name causes real trouble later.
