Italian Civil UnionDifferences from Marriage and How to Use It Abroad

If you have entered into an Italian civil union and need to use this legal status abroad — for residency, inheritance, visa, or family reunification purposes — you will quickly run into a concrete problem: the Italian civil union certificate does not exist in a multilingual format. Unlike the marriage certificate, for which a recognised international model exists, civil unions follow different rules. This guide explains everything: what an Italian civil union is, how it differs from a marriage act, and above all how to obtain a certified sworn translation that is valid abroad.

What is an Italian civil union

The civil union (unione civile) is a legal institution introduced in Italy by Law No. 76 of 20 May 2016 (known as the "Cirinnà Law"). It allows two people of the same sex to establish a State-recognised union, with rights and obligations similar — but not identical — to those arising from marriage.

The Italian civil union is constituted before the Civil Registry Officer (Ufficiale di Stato Civile) of the municipality, in the presence of two witnesses, and is registered in the civil status registers. From that moment, the partners acquire a legally recognised civil status with effects on inheritance, survivor's pension, healthcare and much more.

It is important not to confuse the civil union with de facto cohabitation (convivenza di fatto), which is a different registration status with far more limited legal protections and without a formal act comparable to a civil union certificate.

Differences from a marriage certificate

At the level of civil documentation, Italian civil unions and marriages have substantial differences — both legal and documentary — that are important to understand:

• Eligible parties: marriage in Italy is reserved for opposite-sex couples; civil unions are exclusively for same-sex couples.
• Name of the act: the document is called "marriage act" (atto di matrimonio) for spouses and "civil union act" (atto di unione civile) for civil partners.
• Parentage: marriage automatically produces legal effects regarding parentage (presumption of paternity, etc.); civil unions do not.
• Adoption: stepchild adoption and special adoptions follow different procedures from those applicable to married couples.
• Register: both acts are recorded in civil status registers, but in separate sections.
• Dissolution: marriage is dissolved by divorce; civil union dissolution follows a dedicated procedure under Law 76/2016, generally simpler.
• International format: for the Italian marriage certificate, a multilingual format exists under ICCS Conventions; for civil unions no such format exists.

This last point — the absence of an international format — is what creates the greatest practical difficulties for those needing to use the act abroad.

Available documents: what exists and what does not

When it comes to civil union documents, it is important to clarify what is actually available:

• Extract of the civil union act: a document issued by the Civil Registry Officer containing the essential details of the union (names of partners, date and place of registration). The equivalent of a marriage extract.
• Full copy of the civil union act: a complete reproduction of the original act, including all marginal annotations. Analogous to the full copy of a marriage act.
• Civil status certificate: certifies the person's current civil status (civil union partner, separated, union dissolved). Available from the municipal registry office.
• Multilingual format (ICCS model): DOES NOT EXIST for civil unions. The international conventions providing this for marriage have not been extended to civil unions.

This means that, unlike the multilingual Italian marriage certificate, it is not possible to obtain a document already drawn up in multiple languages that can be directly presented abroad without further formalities.

Why there is no multilingual format for civil unions

The multilingual format for civil status documents is provided for by the ICCS Conventions (International Commission on Civil Status), in particular the Vienna Convention of 1976 and the Vienna Convention of 2016. These international instruments provide standardised multilingual models for birth, marriage and death certificates. Civil unions are not included in these models, simply because the institution was introduced into national legislation after the conventions were drafted, and has not yet been subject to similar international harmonisation. Italy itself has not yet joined specific conventions providing a multilingual format for civil unions.

The practical result is clear: if your civil union partner is a foreign national, if you have moved abroad, or if you need to use this document in a country other than Italy, you will need a sworn translation.

Sworn translation: the only solution for use abroad

A sworn translation (also called a certified or asseverated translation) is the translation of an official document carried out by a translator registered with the court-appointed expert register (CTU), who certifies its accuracy and faithfulness to the original before a public official. It is the only form of translation recognised as a legal equivalent of the original document.

For the Italian civil union act, a sworn translation is required whenever the document must be presented to:

• foreign authorities (immigration offices, consulates, foreign notaries)
• foreign banks or insurance companies
• foreign courts or legal offices
• social security or healthcare bodies in other countries

Unlike the marriage certificate — for which the multilingual format can, in some countries, avoid the need for a translation — for civil unions there is no alternative: a sworn translation is always required. Read our complete guide on Italian sworn translations to understand how the process works.

Our Italian sworn translation service allows you to obtain the translated and certified document entirely online, without having to find a translator, bring documents to the court or handle the bureaucracy yourself.

Apostille on the Italian civil union certificate

If the country where you need to present the Italian civil union act is a signatory to the Hague Convention of 1961, you will need to attach an apostille to the original document (or to the sworn translation, depending on what the foreign authority requires).

An apostille is an official stamp that certifies the authenticity of the signature of the public official who issued the document. It does not attest to the content, but authenticates its origin. In Italy, it is issued by the Prefecture (Prefettura) with territorial jurisdiction.

The typical operational flow for an Italian civil union act to be used abroad is therefore:

1. Request the extract or full copy of the civil union act from the municipality
2. Obtain the apostille from the Prefecture (our apostille service handles this step for you)
3. Have the sworn translation of the apostilled document carried out

In some cases, the foreign authority requires the apostille to be affixed directly to the sworn translation. We always recommend checking with the receiving authority which format is accepted.

How to request the document and sworn translation online

Managing independently a procedure that involves retrieving the Italian civil union act, obtaining the apostille and commissioning a sworn translation can take weeks of queuing at offices, waiting for post and searching for qualified translators. With our service, you can centralise everything in a single order:

• We retrieve the civil union act from the competent municipality
• We manage the apostille process at the Prefecture
• We coordinate the sworn translation with certified translators
• We deliver everything in digital or paper format

No queues, no waiting, no unqualified intermediaries. Also discover our Italian marriage certificate retrieval service if you also need marriage documents.

Conclusion

The Italian civil union act is a document with full legal force in Italy, but when it comes to using it abroad it presents an additional complexity compared to the marriage certificate: it does not exist in a multilingual format. The only viable route is a sworn translation, potentially accompanied by an apostille. Knowing this difference in advance allows you to prepare your documents without wasting precious time — and to avoid rejection by foreign authorities.
