Analysis of Judgment No. 9456 of 2024: Accession and Co-ownership in Buildings

The recent Ordinance of the Court of Cassation No. 9456 of 09/04/2024 provides important clarifications on the issue of accession and co-ownership in condominium contexts. This judgment, issued in a case between S. (B. F.) and R. (V. P.), focuses on exclusive ownership in the case of constructions built on adjacent areas, shedding light on the rights and obligations of property owners. In this article, we will analyze the details of the judgment and its impact on Italian law and established practices.

The Principle of Accession and Exclusive Ownership

The judgment clarifies that, in the case of a unified construction on contiguous lands of exclusive ownership, each owner acquires, by the principle of accession, ownership of the portion of the building that is vertically projected over their land. This means that each owner is entitled to the part of the building that stands on their soil, unless otherwise agreed. This aspect is fundamental to avoid conflicts between neighbors regarding common structures, such as staircases and systems.

Unified construction on adjacent areas of exclusive ownership - Accession - Applicability - Acquisition of exclusive ownership by each landowner of the corresponding vertical portion - Works and structures inextricably serving the entire building - Incidental co-ownership of use and enjoyment - Conditions. In the event that multiple parties, exclusive owners of adjacent areas, agree to build a construction, according to the principle of accession, each of them, unless contrary agreement, acquires only the ownership of the part of the building that is vertically projected over their land, so that even the works and structures inextricably serving the entire building (such as staircases, entrance halls, heating systems, etc.) fall, by accession, wholly or partially, depending on their location, under the ownership of one or the other, unless an incidental co-ownership of use and enjoyment is established on them, as they are functionally inseparable, imposing the obligation on individual owners to contribute to the related maintenance and operational expenses in proportion to their respective ownership rights.

The Implications of Incidental Co-ownership

The judgment also emphasizes the concept of incidental co-ownership of use and enjoyment. When works and structures are functionally inseparable, a co-ownership arises among the owners, which entails the obligation to contribute to maintenance and management costs. This aspect is crucial in a condominium context where expenses can quickly accumulate and become a source of litigation.

  • Common works require shared management.
  • Each owner must contribute in proportion to their ownership rights.
  • Lack of agreement can lead to legal conflicts.

Conclusions

In summary, judgment No. 9456 of 2024 offers a clear view on how the rules of accession and co-ownership should be interpreted in cases of construction on adjacent areas. Owners must be aware of their rights and obligations, especially in complex condominium contexts. It is essential that purchase contracts and agreements between owners are drafted carefully to avoid future disputes. Adequate legal advice is recommended to ensure that the rights of all owners are properly protected.
