When your ex-partner continues to live alone in the house purchased together, the issue is not merely practical. You may wonder whether you have the right to move back in, whether the other party must pay you compensation, whether you can obtain the sale of the property, or whether there is a way to close the co-ownership without resorting to a judicial sale.
The answer changes first and foremost based on the title of enjoyment. An allocation order for the family home, a written agreement between you, or simple occupation protracted after separation produce very different consequences. I will explain which rules govern the use of the shared home, when an economic claim may mature, and which paths can lead to division.
Co-ownership does not assign each person a room in the house
Being co-owners means holding a share of the entire property. If the house is registered 50/50, neither materially owns 'their own half' of the living room, bedroom, or garden: both hold a right over the entire asset, within the equal and concurrent limits of the other.
Article 1102 of the civil code allows each participant in the co-ownership to make use of the common property, provided that they do not alter its destination and do not prevent others from making use of it in a manner consistent with their right. Therefore, the fact that one of the two lives in the house is not always unlawful. It becomes relevant when the occupation concretely excludes the other, despite their willingness to use the property or agree on a different utilization.
Equal use does not require identical presence day by day. The Court of Cassation clarifies that 'equal use' does not coincide with a perfect material alternation of the dwelling; what matters instead is that the behavior of one co-owner does not permanently deprive the other of the possibility of enjoying the asset according to their right. You can read the reference to the limits of the use of common property in the civil review by the Court of Cassation on the topic of co-ownership.
When an allocation of the family home exists
A judge's order can make exclusive enjoyment lawful. If, during separation, divorce, or the regulation of parental responsibility, the family home has been assigned to one of the parents, that permanence cannot be treated as ordinary unlawful occupation between co-owners. Allocation primarily follows the best interests of the children and may also concern a house belonging to both.
The order does not transfer ownership of the other parent's share. However, as long as it is effective, it impacts the right to inhabit the house and must be read alongside other financial and family provisions. Supreme Court jurisprudence links allocation to the preservation of the children's domestic environment; the central point is therefore their concrete situation, not the greater housing need of one of the ex-partners. A useful institutional reference is the review by the Court of Cassation on Article 337-sexies of the civil code.
If allocation is missing or has ceased, the rules on co-ownership become decisive once again. This is an important step: the end of cohabitation, by itself, does not automatically grant either party the right to remain in the property nor does it deprive the other of the faculty to request effective use, an economic agreement, or the dissolution of the co-ownership.
When compensation for exclusive use may be owed
Compensation does not arise automatically from the mere fact that one person lives in the house. If the other co-owner has clearly consented to exclusive permanence, or has remained entirely inactive without manifesting an interest in using the asset, demonstrating that they did not live there is not enough to obtain a sum for the entire elapsed period.
The situation changes when the excluded co-owner expresses the will to use the property, access it, or agree on its enjoyment, and this possibility is denied to them. The Court of Cassation has linked the claim to the civil fruits of the asset, i.e., the economic value that the house could have produced through indirect enjoyment, and specified that the share can be calculated by referring to the hypothetical market rental value. The same review points out that, in relations between co-owners, the request for use left without a positive response is what matters: civil review by the Court of Cassation, exclusive use and civil fruits.
The date of the request may weigh more heavily than the date of separation. A written communication asking to agree on use, hand over keys, or recognize consideration is not a formality devoid of practical effect: it helps distinguish previous tolerance from opposition to exclusive use. However, sending a generic formula is not enough; the content must be consistent with what is actually requested.
How the sum is determined
There is no fixed tariff provided by law. As a rule, one starts from the market rental value of the property in the considered period, takes into account the ownership share of the excluded subject, and verifies circumstances that can reduce, exclude, or otherwise regulate the claim: an agreement between the parties, the allocation of the family home, the actual availability of the property, and any enjoyment of other common assets.
The estimate does not necessarily coincide with the rent that the occupant would have paid to an outsider owner. Here, a lease agreement is not being created: the value of the enjoyment withheld from the other co-owner is being assessed. For this reason, an isolated real estate listing is not always sufficient; location, condition of the house, size, reference period, and market conditions can change the outcome.
Expenses, mortgage installments, and work: what the occupant pays does not erase the other's rights
Property expenses and the cost of living are not the same thing. Taxes, condominium expenses, and necessary work to preserve the property normally concern co-ownership and, in principle, must be divided according to shares. Utilities and consumption generated by someone living alone in the house instead require an assessment linked to actual use.
If one of the co-owners has paid mortgage installments, essential work, or condominium charges alone, those payments may be relevant in economic relations between the parties and in the division. However, they do not automatically authorize occupying the property without limits or entirely retaining the housing benefit. It is necessary to separate levels: who incurred an expense, for which item, with what proof, and with what connection to the shared home.
The mortgage deserves separate attention from ownership. The registration of the financing, the obligation toward the bank, and the ownership of the property do not always coincide. An agreement between ex-partners regarding the house does not automatically release the person who signed the mortgage toward the credit institution. If the goal is the transfer of the share to just one party, the sustainability of the equalization payment and the installment must be addressed before signing, not after.
To guide you, a few targeted documents are needed: the purchase deed and land registry search for shares and formalities, any order regarding the family home, the mortgage contract, condominium statements, receipts for significant expenses, and communications through which the use of the house or an agreement was requested. These documents do not replace the rule, but allow it to be applied to real facts.
How to dissolve co-ownership without confusing the alternatives
Each co-owner can request the dissolution of co-ownership. Article 1111 of the civil code expresses the principle whereby no one is obliged to remain a co-owner indefinitely. In a house, however, dissolving co-ownership does not always mean physically dividing the apartment: first, it must be verified whether the property is comfortably divisible without losing value or function.
When material division is possible, each person can receive an autonomous portion consistent with their share. For an ordinary apartment, this option is frequently impracticable. In such cases, the real options become different: one buys out the other's share; both sell the house to a third party and divide the proceeds; or recourse is made to a judicial division procedure, also requesting the attribution of the entire property to one of the co-sharers with payment of an equalization sum.
Attribution with equalization payment and judicial sale
Sale is not the first and only consequence of a division claim. In ordinary co-ownership, the rules of hereditary division apply, as far as compatible. If the asset is not comfortably divisible, the judge may attribute it to the co-owner who requests it, with the obligation to pay the others the value necessary to balance the shares. If attribution is not practicable, sale may become the solution to transform the asset into money to be divided.
A recent ruling by the Court of Frosinone recalls precisely this sequence: priority of division in kind, then attribution of the indivisible property to the party requesting it, and failing that, sale. The choice between conflicting requests does not depend solely on who currently occupies the apartment: shares, the request for allocation, the ability to pay the equalization sum, and reasons that the judge must motivate all count. See the ruling published by the Court of Frosinone on the division of an indivisible asset.
To avoid a judicial sale, intention must be transformed into a verifiable agreement. Saying 'I want to keep the house' is not enough. A shared or reasonably controllable estimate, a deadline for payment, rules on the mortgage and expenses until transfer, and the notary form necessary for the real estate deed are required. If instead no one can buy out the other's share, an agreed-upon market sale allows the parties to establish times and conditions together, rather than leaving the choice to a legal proceeding.
Mediation and litigation: confrontation is not an optional step to ignore
Prior to a division lawsuit, mediation is normally necessary. Article 5 of Legislative Decree No. 28 of 2010 includes division disputes among those for which mediation constitutes a condition of admissibility for judicial claims. The current text recalled in the Official Journal publication of mediation regulations confirms the inclusion of division among the affected matters.
Mediation can be the place to address together the use of the house until sale, past compensation, the value of the asset, the mortgage, and the transfer of the share. It does not force acceptance of a proposal, but prevents discussion from remaining fragmented into mutual accusations. A well-formulated agreement must precisely indicate who uses the property in the meantime, who pays individual expense items, and what happens if the transfer or sale does not take place within the agreed deadline.
Do not use unilateral initiatives to resolve a co-ownership. Changing locks, removing personal belongings, disconnecting utilities, or preventing access is not a safe shortcut just because you own a share of the house. It can aggravate the conflict and make it more difficult to distinguish the legitimate exercise of a right from the compression of another's right. The useful path is to formulate a clear request and then choose the coherent alternative: a enjoyment agreement, purchase of the share, agreed sale, or division.
Frequently Asked Questions
Can I claim compensation if I have never lived in the house after separation?
You can claim it, but it is not automatic. You must distinguish voluntarily tolerated departure from exclusion from the use of the house against a manifested will. A written request for access, shared use, or economic regulation can be decisive in identifying from what point exclusive occupation produces patrimonial consequences.
Does compensation always correspond to half of the market rent?
Market rent is a criterion, not a rigid formula. The hypothetical rental value can be a starting point, but the actual ownership share, the relevant period, any agreements, the allocation of the family home, and the real conditions of the property must be considered. The result does not necessarily coincide with an ordinary lease agreement.
Can I enter the shared house using my own keys?
Co-ownership does not authorize gestures that fuel conflict. You have a right over the common asset, but if an allocation order, agreements, or a concrete conflictual situation exist, non-agreed access can have further consequences. First, it must be clarified whether a title regulating enjoyment exists and which solution is compatible with it.
Can I force my ex to sell me their share?
You cannot unilaterally impose the purchase of the share. You can propose a price and an agreement, or request the dissolution of co-ownership. In division proceedings, if the house is not comfortably divisible, you can request its attribution with an equalization payment; the judge evaluates the claim and other relevant conditions, without private purchase becoming automatic.
Does the division of the house always lead to an auction?
No, judicial sale is not inevitable. Prior alternatives may exist, such as the purchase of the share, consensual sale to third parties, or, in litigation, the attribution of the entire property to a co-owner who requests it and pays the equalization sum. Sale becomes more likely when the house is indivisible and no one can or wants to acquire it under the necessary conditions.
A criterion for choosing the next step
Before discussing sums, clarify what result you want to achieve. If you wish to use the house again, regulation of enjoyment is needed; if you want to close the patrimonial bond, you need to reason about price, mortgage, and division; if you believe you were excluded, the request, refusal, and relevant period must be reconstructed. Keeping these three levels together avoids asking for a sale when a temporary agreement would suffice, or accepting indefinite exclusive use without establishing its conditions.
