Condominium Clauses and Third-Party Enforceability: The Importance of Transcription in Ruling No. 15341 of 2025

In the complex world of real estate law, the rules governing coexistence within a condominium are fundamental. Among these, condominium regulations, especially those of a contractual nature, can impose significant limitations on the use of individual properties. But what happens when a property with such restrictions is sold? Are these clauses automatically binding on the new buyer? The Court of Cassation, with its ruling no. 15341 of 09/06/2025, provides clarity on this crucial point, thoroughly analyzing the conditions for the enforceability of such restrictions against third parties, emphasizing the importance of correct transcription.

Contractual Condominium Regulations: A Limit on Ownership?

Condominium regulations, particularly the so-called 'contractual' ones, are essential tools for managing condominium life. Unlike assembly regulations, which govern less critical aspects like the use of common areas or decorum, contractual regulations can contain clauses that limit the rights of individual co-owners over their exclusive properties. These limitations, which often prohibit the use of one or more properties for specific purposes (e.g., noisy activities, commercial uses, or specific professions), have the nature of true 'reciprocal easements.' This means that each owner bears a burden on their own property for the benefit of all others, and at the same time benefits from a similar restriction on others' properties.

Enforceability of Clauses: The Cornerstone of Ruling No. 15341/2025

The central issue addressed by the Supreme Court concerns precisely the enforceability of these restrictive clauses against third-party buyers. In other words, if an owner sells their apartment, is the new buyer automatically bound to respect the usage restrictions imposed by the contractual regulation, even if they were not directly aware of them at the time of purchase? The Cassation's answer, with ruling no. 15341 of 2025, is clear and based on a fundamental principle of our legal system: real estate publicity through transcription.

The enforceability against third-party buyers of condominium regulation clauses that, by prohibiting the use of one or more exclusive properties for a certain purpose, constitute reciprocal easements, is subject to the transcription of the burden, according to the regulations in force at the time it is made, and therefore: by indicating, in a separate note from the purchase deed, the specific restrictive clauses, pursuant to art. 17, paragraph 3, of law no. 52 of 1985; before the entry into force of this law, by indicating them in the sole transcription note filed for the sale, pursuant to art. 2659, paragraph 1, no. 2, and 2665 of the Civil Code, a general reference to the regulation itself not being sufficient for this purpose; during the validity of art. 1940 of the Civil Code of 1865, provided that the nature of the reciprocal easement stipulated concurrently with the sale and the properties to which it pertains are identifiable from the content of the transcription note.

This maxim is of fundamental importance because it establishes that a simple reference to the condominium regulation in the purchase deed is not sufficient to make restrictive clauses enforceable against the new owner. The Court, in fact, emphasizes how the validity of such restrictions against third parties is strictly linked to their proper publication in the real estate registers. The ruling overturned a decision by a Court of Appeal that had deemed a clause prohibiting the use of a property as a music school enforceable against D. (the third-party buyer). In the specific case, the 1938 sale deed indicated knowledge and acceptance of the condominium regulation transcribed in 1937, but the Cassation requested verification of whether the transcription note had specified not only the existence of the regulation but also the restrictive clause itself. This highlights how precision in transcription is crucial.

The Supreme Court clearly distinguishes the transcription methods according to the period in which it occurred:

• **After the entry into force of Law No. 52 of 1985 (Art. 17, paragraph 3):** The indication of specific restrictive clauses in a note separate from the purchase deed is required. This ensures maximum clarity and transparency for anyone consulting the registers.
• **Before Law No. 52 of 1985:** The indication of the clauses in the sole transcription note filed for the sale, pursuant to art. 2659, paragraph 1, no. 2, and 2665 of the Civil Code, was sufficient. However, even in this case, a general reference to the regulation was not enough, but an explicit mention of the restrictive clause was necessary.
• **During the validity of the Civil Code of 1865 (Art. 1940):** It was necessary for the nature of the reciprocal easement stipulated concurrently with the sale and the properties to which it pertained to be clearly identifiable from the transcription note.

The Crucial Importance of Transcription for the Protection of Rights

The principle of transcription, governed by articles 2643 et seq. of the Civil Code, is the cornerstone of the Italian real estate publicity system. Its function is to make certain legal acts public, rendering them enforceable against third parties. Without proper transcription, an act, although valid between the parties, may not produce effects against those who were unaware of it and acquired rights on the same property. In the context of condominium easements, this means that a buyer who does not find explicit mention of the restriction in the real estate registers cannot be considered bound, even if the seller was aware of it.

This ruling reinforces the need for scrupulous diligence on the part of those who purchase property and those who draft sale deeds. Mere knowledge of a condominium regulation, or a general reference to it, is not a guarantee of enforceability. It is the specific and detailed transcription of individual restrictive clauses that gives them full effect erga omnes, i.e., against everyone, including future buyers.

Conclusions: Diligence and Awareness for Secure Purchases

The Cassation ruling no. 15341 of 2025 represents an important warning for all players in the real estate market. For potential buyers, it is essential not to limit themselves to reading the condominium regulation but to request a careful verification of the transcription notes related to the property and the regulation itself, to ascertain the existence and proper publicity of any restrictive clauses. For sellers and industry professionals (notaries, lawyers, real estate agents), it is essential to ensure that every restriction on the property is correctly transcribed, in order to guarantee legal certainty and prevent future disputes. Only precise transcription, compliant with current regulations, can fully protect the rights of all parties involved, ensuring transparency and security in real estate transactions.
