ABSTRACT: When a couple living in Italy separates, the financial outcome depends entirely on whether they married, formed a civil union, or simply cohabited — and when they started. A landmark 2025 ruling by the Italian Court of Cassation has clarified how pre-formalisation cohabitation is counted in civil union dissolution claims, dramatically affecting what foreign partners can recover. This article explains the three-tier Italian framework, the critical dates, and what international couples must do before a relationship ends.

The question nobody asks — until it is too late

An Australian woman moves to Milan to be with her Italian partner. They live together for four years before registering a civil union. Three years later, the relationship breaks down. She gave up her career and her country. Now she wants to know what she can claim in Italy.

The answer is not what she expects — and whether those four pre-registration years count is precisely what the Italian Court of Cassation spent 2023 and 2025 resolving.

Italy's three-tier structure: not one system but three

Law no. 76 of 2016 introduced civil unions into Italian law, governing same-sex couples, and separately addressing cohabitation. The two institutions are not interchangeable. Italy now operates what is best understood as a strict hierarchy of recognised partnerships, each carrying different rights at dissolution.

At the top sits marriage (matrimonio), with the fullest set of protections. Below it is the civil union (unione civile), created by Law no. 76/2016 — known informally as the Legge Cirinnà after its parliamentary sponsor — and available only to same-sex couples. At the base sits registered de-facto cohabitation (convivenza di fatto), available to any couple regardless of sex or orientation, which carries significantly fewer rights.

A civil union and marriage remain governed by two distinct bodies of law, but with many points of contact. Cohabitation, by contrast, is governed by a sparser statutory framework with significant lacunae.

What changes at dissolution — and what the 2025 ruling decided

When a civil union ends, the financial support question is central. Because there is no separation phase in civil unions (unlike in marriage), a maintenance allowance does not apply. What can be awarded after dissolution is a post-dissolution support payment equivalent to the divorce allowance (assegno divorzile).

The legal basis is Article 1, paragraph 25, of Law no. 76/2016, which expressly incorporates the provisions of the Divorce Act (Law no. 898 of 1 December 1970). The Italian Court of Cassation, First Civil Division, order no. 25495 of 17 September 2025 (Cass. civ., Sez. I, ord. 17 settembre 2025, n. 25495) confirmed that the full divorce-allowance criteria apply to civil union dissolution: the economic imbalance between the partners, the contribution each made to the shared life, and the choices made during the relationship are all weighed.

The truly consequential part of the ruling, however, concerns what happens before the formal registration. The more consequential question is whether cohabitation predating registration of the civil union. The Italian Court of Cassation, United Sections, judgment no. 35969 of 27 December 2023 (Cass. civ., SS.UU., sent. 27 dicembre 2023, n. 35969) addressed the relevance of pre-registration de-facto cohabitation for the purposes of determining the support allowance upon subsequent civil union dissolution. The United Sections — the highest formation of the Italian Court of Cassation — held that those earlier years of shared life are not simply ignored. They form part of the factual picture the court must examine when assessing the compensatory and equalising function of the allowance.

For a foreign client, the practical translation is this: if you lived together in Italy for years before registering, that period has legal weight. If you never registered at all, the framework changes entirely.

Under the consolidated rule restated by Italian Court of Cassation, First Civil Division, order no. 20030 of 15 June 2026 (Cass. civ., Sez. I, ord. 15 giugno 2026, n. 20030), the claiming partner must plead and prove a material contribution to the couple's shared life — whether through care, sacrifice of professional opportunities, or economic contribution — before any post-dissolution allowance is awarded. An income disparity alone is not enough.

The cohabitation trap: what you cannot claim without a contract

A de-facto cohabitant (as opposed to a civil union partner) is not entitled to a maintenance allowance at all. The only financial remedy available, where genuine need is shown, is a basic subsistence payment (assegno alimentare) from the former partner. Even that subsistence payment is not guaranteed; it is available only where the recipient cannot otherwise support themselves, and it is proportionate to how long the couple lived together — there is no standard amount.

This is the cohabitation trap that foreign clients consistently underestimate. A couple who lived together in Italy for a decade without registering their relationship has none of the financial protection on separation that a civil union partner would have. The longer-earning partner walks away with the full benefit of any career advantage gained during the relationship.

The Italian Civil Code (codice civile) does offer one limited remedy in this scenario. The Italian Court of Cassation, Third Civil Division, order no. 11337 of 30 April 2025 (Cass. civ., Sez. III, ord. 30 aprile 2025, n. 11337) addressed the question of expenses paid by one de-facto partner to or on behalf of the other during the relationship and whether those sums could be recovered once the relationship ended. The ruling confirms that restitution is possible in limited circumstances, but the legal route is a general-law claim rather than a family-law remedy — harder to run, slower to enforce, and far less protective.

Unlike in common-law countries: the gap that surprises British, Australian and American clients

Unlike in England and Wales, where a cohabiting partner who has contributed to property or shared finances may rely on constructive trust principles, proprietary estoppel, or the Trusts of Land and Appointment of Trustees Act 1996 to claim an interest in real property, Italian law does not recognise any equivalent equitable doctrine for cohabitants. Italy has no concept of common intention constructive trust. A foreign partner who paid towards a property owned solely in their Italian partner's name will not automatically acquire any legal or equitable interest in it merely by virtue of cohabitation or financial contribution. The only protection is a written, notarised cohabitation contract (contratto di convivenza) executed before the contribution is made, or a co-ownership deed at the time of purchase.

In the United States, some states recognise palimony or impose constructive remedies on the dissolution of long-term cohabitation. Italy does not. Only where genuine need is shown can a de-facto cohabitant claim even a basic subsistence payment from a former partner. Career sacrifice, emotional contribution, and years of shared life generate no automatic financial remedy under Italian law — only a thin, means-tested allowance of last resort.

Italian case law has, over recent years, progressively reduced the differences between married spouses and stable cohabitants in specific fields, but the dissolution rights remain sharply differentiated. That gradual convergence does not yet reach financial remedies upon separation.

What foreign couples should do — in order

The hierarchy of risk — and the steps to manage it — runs as follows.

If you are in a same-sex couple and have lived together in Italy, check the date your relationship became stable and whether a cohabitation agreement or civil union registration exists. Both dates will matter if the relationship ends. If you have not registered, assess whether doing so protects you: civil union partners acquire inheritance rights, a reversionary pension, and post-dissolution support for the economically weaker partner. De-facto cohabitants have none of those automatically.

If you are in an opposite-sex couple living together in Italy, you have the right, but not the obligation, to draw up a cohabitation contract under paragraph 50 of Law no. 76/2016. The contract has exclusively patrimonial content — it deals with property, not status — and must be executed by notarial deed or authenticated private deed to be enforceable. Without it, any property held in one partner's name alone belongs to that partner exclusively.

Before buying property in Italy as an unmarried couple, obtain a land registry search (visura catastale) to confirm the current ownership position, take legal advice on how to structure title, and — critically — record any financial contributions made by each partner in a written instrument at the time, not retrospectively.

If you believe a pre-existing cohabitation period should be counted in computing any post-dissolution entitlement, document it: tenancy agreements, joint utility accounts, municipal registry (Anagrafe) registration at the same address, and dated correspondence all serve as evidence.

Finally, note the interaction with EU private international law. Regulation (EU) 2016/1104, which governs the property consequences of registered partnerships (including civil unions), applies in Italy from 29 January 2019. Where both partners are non-Italian, the law applicable to their property regime at dissolution will be determined by this Regulation — not automatically Italian law. The choice-of-law question should be addressed at the outset of the relationship, not during dissolution.

Nemo plus iuris ad alium transferre potest quam ipse habet — no one can transfer more right to another than they themselves possess. The principle applies with equal force to the financial claims a separating partner brings: the rights transferred on dissolution are exactly those that the chosen legal framework, at the moment of formalisation, recognised as existing. Choose the framework late, and you may find it transferred very little at all.

As the legal theorist Mary Ann Glendon observed in her comparative study of family law, the gap between what couples believe their relationship confers and what the law actually provides is widest precisely where social recognition of the relationship is highest but legal formalisation has not followed. In Italy today, that gap sits squarely between the civil union and the unregistered cohabitation — and it is measured in euros at the moment of dissolution.

LOCAL NOTE:
1. Search intent targeted: transactional + informational hybrid — the reader is a foreign national in or moving to Italy, in a same-sex or opposite-sex non-married relationship, who needs to understand their financial exposure if the relationship ends; high instructing-lawyer intent.
2. Local-market framing used: explicit contrast with English constructive trust / proprietary estoppel doctrine (relevant for UK, Australian and Irish readers) and US palimony (relevant for US readers); both positioned as assumptions that do not travel to Italy; framing via the question "what can I claim?" rather than abstract legal exposition.
3. Italian terms kept untranslated (in italics, explained on first use): *assegno alimentare* (subsistence/basic maintenance payment, retained because the English "maintenance" is ambiguous between the separation allowance and the post-dissolution allowance and could mislead); *convivenza di fatto* (de-facto cohabitation, retained alongside the English phrase to match what Italian official documents use, since foreign clients will encounter it on forms); *Anagrafe* (municipal civil registry, retained because no single English word captures the institution and clients will see it on Italian correspondence).
