Start at the town hall that holds the entry
A birth record lives at the comune where the birth was logged. Naples keeps its own, in the Ufficio di Stato Civile at the town hall. So how to apostille a Birth Certificate starts at that counter, not at the office nearest the home you live in today.
Ask for the right form while you are there. A short extract gives the name, place and date. A full copy, the estratto per copia integrale, also shows notes added later, such as a marriage or a change of name. Desks abroad often want the full copy, so check before you queue.
Who adds the stamp, and what it proves
To apostille a Birth Certificate in Italy the paper must be a live one, signed and sealed by the registrar. An apostille is a slip the state adds to prove that hand is real. It says nothing about the birth itself, so a wrong spelling stays wrong once stamped.
You apostille a Birth Certificate in Naples at the Prefettura (Prefecture), the state's local office, because a civil record counts as an administrative paper. Judicial and notarial papers go elsewhere, to the Procura della Repubblica at the court. A court order that fixed a name would follow that second route.
Read the sheet before you leave the town hall. Check every letter of the names, the date and the place. A file abroad is refused when the record and the passport disagree, and fixing that sends you back to the registrar first. Ask for two originals if more than one desk will keep a copy.
The fee and when to start
The apostille cost for a Birth Certificate in Naples is a €16 tax stamp per document, and some papers are exempt. The clerk decides that from the use you write on the form, so bring the letter or list from the desk abroad. Waits are not fixed, so start in the week you learn you need it.
What people need it for
This is the paper people need most often. A wedding abroad, a visa file, a school place, a claim to a second passport, a pension or an estate case can all turn on it. Each desk sets its own rule about which form it takes and how old it may be. Ask them in writing, then order to match.
Translation and acceptance notes
Older forms still ask for the legalisation of a Birth Certificate in Naples. Within the Hague group the apostille has taken that place. Where the paper is bound for another EU state, ask first: EU rules can drop the stamp for records like this. Outside both, the embassy route may still hold.
Most desks want the text in their own language too. The facts here name none, so ask the office that will read it. For a sworn version the translator swears the asseverazione, a signed oath before a Tribunale (court) that the words match. Ask whether they want that oath bound to the stamped record or kept loose.
