De facto cohabitation produces specific protections, but it does not automatically grant all the rights provided for married couples or civil union partners. If you live stably with your partner, you may therefore wonder what needs to be declared to the Municipality, whether a self-certification is sufficient and what effects it produces on the home, assets, healthcare or succession.
I want to help you distinguish three levels that are easily confused: the emotional bond and cohabitation, civil registration, and property agreements. I will explain which requirements define de facto cohabitants, what the civil registration declaration proves and what additional tools you can consider when you wish to protect your assets, your home, or your partner in the event of death or the termination of the relationship.
When the law recognizes two people as de facto cohabitants
Not every cohabitation is a de facto cohabitation. Article 1, paragraph 36, of Law No. 76 of May 20, 2016 requires two adult persons, stably united by an emotional couple bond and by mutual moral and material assistance. The rules apply to both different-sex and same-sex couples.
Cohabitants must not be bound to each other by family ties, affinity or adoption, and neither of them can be bound by marriage or a civil union. Personal separation does not dissolve marriage: a person who is separated but not divorced remains married and does not fall within the definition provided by paragraph 36 with a new partner.
Stability does not depend solely on the time spent together. Common life, cohabitation and mutual assistance matter, while the law uses the civil registration declaration as a reference to ascertain stable cohabitation. The fundamental discipline is contained in paragraphs 36 and following of Law No. 76 of 2016 on civil unions and cohabitations.
Civil registration declaration and self-certification are not the same thing
Cohabitation must be declared to the civil registry of the Municipality where the partners cohabit and have their habitual residence. The reference is to the registered family, meaning the group of people who habitually live together and are bound, in this case, by emotional ties. The registration regulations also contemplate the establishment of a new family and subsequent variations in its composition.
The declaration does not create an otherwise non-existent emotional relationship by itself and does not replace the requirements established by law. However, it makes the registration situation verifiable and constitutes the reference indicated by paragraph 37 to ascertain stable cohabitation. The composition of the registered family is governed by Article 4 of Presidential Decree No. 223 of 1989, in the wording also referred to by Legislative Decree No. 5 of 2017.
Self-certification performs a different function. Article 46 of Presidential Decree No. 445 of 2000 allows data such as residence and family status to be declared in place of the relative certificates. You can self-certify what is correctly registered: self-certification does not replace the communication necessary to update the civil registry and does not allow claiming a status that does not correspond to facts or records.
Administrations can carry out checks, and untruthful declarations entail the responsibilities provided by law. For this reason, it is useful to distinguish the form used to communicate cohabitation to the Municipality from the subsequent substitute declaration used to prove residence or family status. The reference is Presidential Decree No. 445 of 2000, Article 46.
Registered family and household do not always coincide. Being registered in the same family status does not automatically ensure access to every benefit. Social services, taxes and rankings may apply their own definitions, which must be considered in relation to the individual application.
What rights derive from de facto cohabitation
Health, hospitalization and personal decisions
In case of illness or hospitalization, cohabitants have the mutual right to visit, assistance and access to personal records according to the organizational rules established by the facility for spouses and family members. Civil registration can make it easier to prove the relationship when the hospital must identify authorized persons.
Each cohabitant may also designate the other as their representative, with full or limited powers, for healthcare decisions in the event of incapacity to understand and intend. The designation may also concern, after death, organ donation, body treatment and funeral celebrations. A written and handwritten declaration is required or, if it is materially impossible to draft it, a declaration made in the presence of a witness.
Common home and lease agreement
The protection of the home varies according to the legal title to the property. If the property belongs to the deceased partner, the surviving cohabitant may continue to live there for two years or, if the cohabitation lasted longer, for a period corresponding to its duration, up to a maximum limit of five years. If minor children or disabled children of the survivor live in the home, the period cannot be less than three years.
This is a temporary right of habitation, not an acquisition of ownership nor an inheritance share. It terminates if the survivor stops living stably in the house or contracts marriage, establishes a civil union or starts a new de facto cohabitation. Decisions adopted in the interest of children regarding the family home also remain central.
If, on the other hand, the home is rented, the cohabitant can succeed in the lease agreement when the tenant dies or withdraws from the relationship. In public housing rankings, belonging to the cohabitation may also assume the same relevance recognized to the household, subject to the other required conditions.
Personal protection and work in the family business
The cohabitant may be appointed guardian, conservator or support administrator of the other, when the conditions established by law are met. If one of the partners dies due to the unlawful act of a third party, the survivor's loss is assessed using the criteria applied to the spouse, without prejudice to the need to prove the relationship and the prejudice suffered.
Important protection also concerns those who work continuously in the partner's family business. The Constitutional Court, with judgment No. 148 of 2024, included the cohabitant among the family members protected by Article 230-bis of the Civil Code and eliminated the more limited discipline of Article 230-ter. This entails the patrimonial and participatory prerogatives provided for work in the family business, when a different corporate or employment relationship does not exist. You can consult judgment No. 148 of 2024 of the Constitutional Court.
What registration does not automatically grant
The cohabitant does not become an heir by law. Civil registration does not grant a share of the inheritance, unlike what happens for the spouse or the party to a civil union. To leave assets to the partner, a will is normally required, respecting the shares that the law reserves for any forced heirs, such as children, the non-divorced spouse and, in certain situations, ascendants.
Even the temporary right to remain in the deceased partner's home is not equivalent to succession. A will and the right of habitation serve different needs: the former can allocate assets within permitted limits; the latter temporarily protects housing continuity under the conditions provided by law.
Registration does not make assets already owned nor those subsequently acquired common property. If the house is registered in the name of a single cohabitant, the other does not acquire a share because they contribute to daily expenses or because they appear in the same family status. Ownership, loans and financial contributions remain distinct issues, to be documented consistently with what the parties intend to achieve.
Furthermore, cohabitation does not entail all the personal obligations of marriage. In the event of separation, a maintenance allowance analogous to spousal maintenance does not arise automatically. Rights and duties towards children, however, do not depend on the parents' marriage: custody, maintenance, education and care follow the rules established for the protection of children.
The cohabitation agreement to organize economic relations
The declaration to the Municipality does not replace a property agreement. If you wish to establish how to contribute to common needs, indicate your residence or choose the legal regime of community of property, you can execute a cohabitation agreement pursuant to paragraphs 50 and following of Law No. 76 of 2016.
The agreement, amendments and termination must be drawn up in writing, under penalty of nullity, by public deed or private instrument with signatures authenticated by a notary or a lawyer. The professional certifies the compliance of the agreement with mandatory rules and public policy and transmits a copy to the Municipality within ten days for civil registration and opposability to third parties.
The choice depends on the objective. Registration alone documents cohabitation and allows access to the protections provided by law. The agreement regulates certain economic relations of common life. A will, on the other hand, serves to dispose of assets after death, while joint purchase immediately attributes to both a share of the asset indicated in the deed. One instrument does not necessarily replace the others.
The agreement cannot transform the cohabitant into a legal heir and does not transfer the ownership of a property by itself. Nor can it be subject to a termination date or a condition. It can be modified during cohabitation in the same forms provided for execution and is dissolved by agreement, unilateral withdrawal, marriage or civil union, and death of a party.
In unilateral withdrawal, the professional must notify the other contracting party of the deed. If the family home is at the exclusive disposal of the withdrawing party, the deed must grant at least ninety days to vacate the premises. This guarantee concerns that specific hypothesis and does not constitute a general term applicable to the end of any cohabitation without an agreement.
What happens when cohabitation ends
To interrupt the relationship, a separation such as that provided for spouses is not required. However, it is necessary to communicate the registration variation when cohabitation ceases and, if a cohabitation agreement exists, respect its forms of dissolution. Jointly owned assets, loans and documented expenses maintain the discipline proper to each relationship.
If there are children, the termination of cohabitation does not reduce parental obligations. Decisions must regulate their residence, times with each parent and the contribution to maintenance, placing their best interests at the center. Couple conflict and responsibilities towards children remain separate planes.
The financially weaker cohabitant has no automatic right to maintenance, but may ask the judge for alimony if they are in a state of need and unable to provide for their own sustenance. Alimony covers essential needs and does not guarantee the previous standard of living. The duration is proportional to that of the cohabitation and the amount follows the criteria of Article 438 of the Civil Code.
Frequently asked questions
Is having the same residence enough to be de facto cohabitants?
The same residence is not enough by itself. There must also be a stable emotional couple bond, mutual moral and material assistance, and the absence of impediments indicated by the law, such as marriage, civil union, family ties, affinity or adoption between partners. Civil registration documents cohabitation, but it must correspond to reality.
Can I self-certify cohabitation without going to the Municipality?
Self-certification does not update the civil registry. It can replace a certificate to attest residence and family status already registered. If you need to communicate a new residence or the establishment of the registered family, you must follow the procedure set up by the Municipality and make declarations corresponding to habitual residence and the existing relationship.
Does registration make me my partner's heir?
No, the cohabitant is not a legal heir. In the absence of a will, inheritance follows the categories provided by the Civil Code. A will can protect the partner within the limits of the disposable quota, without harming the rights of any forced heirs. The temporary housing protection provided for the common home owned by the deceased cohabitant remains distinct.
Can we make assets common with a cohabitation agreement?
The agreement can choose community of property and regulate contributions to common life, but it must respect the form and content established by law. A privately signed writing is not enough: a public deed or a writing with signatures authenticated by a notary or lawyer is required, followed by transmission to the Municipality.
After the end of cohabitation can I ask for maintenance?
There is no automatic maintenance analogous to spousal maintenance. The judge can recognize alimony only if you are in a state of need and cannot provide for essential needs. The duration is proportional to that of cohabitation. Any documented credits and child maintenance obligations remain separate.
How to choose the right protection
Start from the concrete objective. The civil registration declaration serves to document cohabitation; the agreement regulates certain property relations; joint ownership and a will affect ownership and succession respectively.
