Direct answer
A marriage validly celebrated in Italy generally does not need a second registration in the UK or the US. UK recognition also depends on the marriage being permitted under UK law. In the US, recognition questions can depend on the state and the purpose for which you need to prove the marriage.
What you may need is a copy of the Italian certificate, sometimes with an apostille, when an institution asks you to prove the marriage.
If a US authority asks for the certificate, do not assume it needs an apostille. Ask what that authority accepts first. An apostille authenticates the Italian public document for cross-border use; it does not create or register the marriage.
A valid Italian marriage generally needs no second UK or federal US registration. Get a certificate, apostille or translation when the receiving authority requires it.
Common misconception

- Apostille
- Register at home No general UK or federal US step
Where the marriage is recorded
For a civil ceremony, the record is made at the time. The Ufficiale dello Stato Civile who marries you enters the act in that comune’s civil status registers during the ceremony (Ministero dell’Interno).
For a Catholic ceremony, the record is made afterwards. The priest requests transcription in writing within five days of the ceremony, and the registrar completes it within twenty-four hours of receiving the act (Law 121/1985, art. 8).
The marriage has civil effect from the moment of the ceremony, not from the date of transcription, even where the registrar transcribes late. A late transcription may be requested by both spouses, or by one spouse if the other knows and does not object, provided both have remained continuously free to marry; rights lawfully acquired by third parties are protected (same source). Still worth confirming it was done, because the certificate you will later need comes from that register entry.
Either way, the record remains in the civil-status system for the comune where you married, and the comune can issue certificates later. Since 31 March 2026, certificates already available in the national ANSC archive can also be downloaded free through ANPR; extracts can be requested and tracked there. The online route depends on the record being available in ANSC.
Getting the certificate
Ask the institution that wants the document which form it needs before you request anything, and ask your comune what it issues. Practice and fees vary between comuni.
There is also a multilingual extract under the 1976 Vienna Convention, usable in the countries party to it without translation or legalization (Comune di Vinci). Neither the UK nor the US appears on the current list, so the form does not provide this Convention’s exemption from legalization or translation for use there. The receiving authority still decides what it requires.
Apostilles: which office
An apostille authenticates the signature, the signer’s capacity and, where applicable, the seal or stamp on a public document. It does not certify the document’s contents or guarantee that a receiving authority will accept it. Which Italian office issues it depends on what the document is.
- The marriage certificate is an administrative act signed by the civil registrar, so its apostille comes from the Prefettura (Procura di Ravenna).
- A sworn translation completed by a translator registered with an Italian court is handled by the Procura della Repubblica (Prefettura di Milano).
If you need both the certificate and a sworn translation apostilled, that can mean two documents at two different offices. Prefettura Milano works by appointment and requires a €16 revenue stamp only when the original was issued subject to stamp duty; an exempt original does not require the stamp (Prefettura di Milano). Other prefetture set their own arrangements. For how much this can vary office to office, see our guide on official costs.
Recognition at home: the UK and the US
The UK: nothing to register
There is no UK registration step, and there has not been one since 2014.
GOV.UK says there is no legal requirement to deposit a foreign marriage certificate with the General Register Office and that depositing it did not affect the marriage’s validity in UK law. The Foreign and Commonwealth Office discontinued that service on 1 January 2014 (GOV.UK).
A marriage abroad is recognized in the UK when it was lawful in the country where it took place and would be allowed under UK law (GOV.UK).
The US: nothing to register
A marriage validly performed in Italy does not need a second federal registration step. For a specific recognition or documentation question, the US Department of State directs you to the Attorney General’s office in the state where you live.
How to legalize an Italian marriage certificate for use in the US
There is no single sequence for every US use. Before ordering an apostille or translation, ask the agency or institution receiving the certificate whether it needs the comune-issued certificate or extract, an apostille, a full English translation, or a particular combination.
- Name the receiving authority and the exact purpose, such as an immigration filing or a name change.
- Ask that authority which Italian record it accepts and whether it requires an apostille or translation.
- Request that record from the comune where the marriage was registered, or use ANPR if the required certificate is available there.
- If an apostille is required for the certificate, use the competent Prefettura. Follow the receiving authority’s translation standard separately.
Italy and the United States both use Hague apostilles instead of embassy or consular legalization for covered public documents (Italian Embassy in Washington). The apostille confirms the document’s authenticity for cross-border use; it does not replace the receiving authority’s evidence rules.
If the receiving authority is USCIS
For immigration purposes, USCIS generally applies the place-of-celebration rule, and a marriage certificate is usually initial evidence that the marriage was properly and legally performed (USCIS Policy Manual, Volume 12, Part G, Chapter 2). A foreign-language document must have a full English translation with the translator’s certification that it is complete and accurate and that the translator is competent. USCIS’s general evidence rules allow a legible photocopy unless the applicable form instructions require an original, and USCIS may later request the original (USCIS Policy Manual, Volume 1, Part E, Chapter 6). Check the instructions for the exact form before filing.
If the receiving authority is Social Security
Use the current Social Security name-change flow. SSA says most requests can be made or started online; if you cannot use its online services, complete Form SS-5 and show the required documents. SS-5 accepts originals or copies certified by the custodian of the original record, not notarized copies or uncertified photocopies. SSA’s specific public policy page for a name change based on a foreign marriage, POMS RM 10212.050, currently returns an error, so this guide does not claim a universal SSA apostille or translation rule. Confirm the document route in SSA’s guided flow or at the appointment.
Why the myth persists
The idea that a foreign marriage must be registered at home is widespread, and the UK once ran a deposit service that made it look mandatory. That service was withdrawn in 2014, and the guidance above says plainly that depositing a certificate never affected the validity of the marriage.
You may still want extra certified copies, and an apostille when an institution asks for one. That is document logistics rather than registration.
What to do
- Confirm the marriage was entered in the comune’s register: at the ceremony for a civil marriage, and shortly after for a Catholic one, once the priest has filed the act.
- Request the required certificate from that comune, or use ANPR if it is available there, having first asked the receiving institution which form it wants.
- Get an apostille only when the receiving authority requires it. Use the Prefettura for the certificate and the Procura for a sworn translation.
Before you rely on this
Practice varies by comune, and US document requirements vary by receiving authority and, in some cases, by state. UK recognition also depends on the marriage being allowed under UK law. This guide states USCIS’s general evidence rules and SSA’s current public name-change instructions. A form, field office or case-specific request may require more. SSA’s dedicated foreign-marriage policy page remains unavailable, so we do not claim a universal SSA apostille or translation rule. Confirm the exact document set with the authority handling your case.
This guide covers what happens to your certificate once you’re home. It does not cover which ceremonies are legally binding in the first place (see our guide on which ceremonies are legally binding in Italy), what your comune needs from you before it will confirm a date (see our guide on comune requirements), where a civil ceremony can legally take place (see our guide on where you can legally marry in Italy), what any of this costs (see our guide on official costs), or what your guests need to enter the country (see our guide on guest entry requirements).
US citizens who are still arranging the marriage can start with our US-citizen process Guide; this Guide begins after the comune has created the record.
British nationals who are still arranging the marriage can start with our UK-citizen process Guide; this Guide begins after the Comune has created the record.
