The copy the registry issues
The judge keeps the ruling. What you can take away is a copia autentica, a copy the cancelleria certifies as matching the file. Order it from the registry of the section that heard the case, quoting the case number and the date of the ruling. Say clearly that the copy is going abroad, because that changes what the clerk writes on it.
Read the copy before you leave the building. It should carry the clerk's signature in ink, a date, the court's seal and every page of the ruling including the operative part. A copy missing its last page is worthless at a consulate, and you will not find out until the queue reaches you.
Proof that the ruling is final
Most readers abroad want more than the text of the decision. They want to know that nobody can still appeal it. The registry can add an attestation that the ruling has passed into giudicato, meaning the time for appealing has run out. Ask for that note at the same time as the copy, since a second trip to the same counter is a wasted morning.
This is the point where how to legalize a court order differs from most other papers. The Italian stamps say nothing about whether a decision is final; they only vouch for a signature. If your reader needs finality, the registry must state it on the sheet itself before anyone stamps anything.
The Procura signs for the clerk
Padua sends judicial and notarial papers to the Procura della Repubblica, and office papers from a Comune, a school or a chamber to the Prefettura, also written Prefecture. A judgment is plainly judicial. So the Procura at the Tribunale di Padova legalises the registry clerk's signature. Embassy legalization of a court order in Padua never begins anywhere else.
Costs and days
Two charges, one of them fixed. The €16 marca da bollo is the Italian tax stamp and costs the same everywhere; the registry may also charge for the copy itself. The consulate then names a fee of its own, published on its site and changed when it chooses. Allow 10–15 business days between the registry and the consular seal, or 3–5 business days where a mission will compress it.
What it is used for abroad
Rulings travel for concrete reasons. You may need to enforce a debt, register a change of status, settle an estate, or show a foreign court that a matter is already decided. Each of those readers wants consular legalization of a court order in Italy so that the sheet in front of them is provably the real one. Ask each reader what it needs before you order copies.
Whether the consular seal is owed at all depends on the destination country, so ask the receiving authority to confirm in writing. Where a sworn version is wanted as well, have it made before the Procura signs. A single seal then covers both sheets, and you legalize a court order in Padua only once. Then book embassy attestation of a court order in Padua on the finished bundle.
