Union of Co-Ownership Associations: Who Owns the Common Facilities? The Court of Cassation's Answer

Imagine you own a flat in a residential complex in Mont-de-Marsan. Your building is part of a larger development with a swimming pool, lifts, and underground car parks shared with other buildings. Each month, you pay your co-ownership charges, but a portion also goes to a "union of co-ownership associations" that manages these common facilities. One day, the swimming pool requires major works: €80,000 to be allocated. Who should pay? The union? Your association alone? All the co-owners in the development?

This question is not theoretical. undefined between Mont-de-Marsan and Dax, I have seen conflicts erupt over these shared facilities. Owners wonder: "If I pay for this facility, do I actually own it?" Managing agents question how to allocate costs. Buyers hesitate in the face of potentially unpredictable charges.

The Court of Cassation provided a clear answer on 21 January 2021. But what exactly does this change for you? Does this decision revolutionise the management of unions of co-ownership associations or simply confirm what professionals already suspected? Let's delve into this case that concerns thousands of co-ownerships in France, particularly in our region where developments with shared facilities are multiplying.

The Facts: A Story That Happens Every Day

Mr Dubois, owner of a flat in the Résidence des Pins in Dax, discovers with astonishment a summons for an extraordinary general meeting. The union of co-ownership associations that manages the swimming pool and underground car park shared by three buildings proposes renovation works for €120,000. According to the draft resolution, his association (that of building B) should bear 60% of the cost, while the two other buildings would pay only 20% each.

"But why?" protests Mr Dubois at the meeting. "We use the swimming pool like the others!" The union president explains that building B has more flats and its residents use the facilities more. The co-owners of building B reject the resolution, arguing that ownership of the facilities should be allocated equitably among all the member associations of the union.

The conflict escalates. The union commissions the works and invoices building B. The co-owners refuse to pay. The case reaches the judicial tribunal of Mont-de-Marsan, then the court of appeal of Pau. Each judicial stage takes months, generates legal fees (several thousand euros), and poisons the life of the co-ownership. Relations between neighbours deteriorate, flat sales are compromised by legal uncertainty.

Finally, the union seises the Court of Cassation. The central question is simple in appearance but complex in law: who owns the common facilities managed by a union of co-ownership associations? The union itself? The member associations proportionally? Or a single association with mere usage rights for the others? The answer goes well beyond this particular case.

The Court's Reasoning — Analysed

The judges of the Court of Cassation analysed this case with surgical precision. They first recall the legal framework: a union of co-ownership associations is a structure created by several co-ownership associations to jointly manage common facilities or services (article 26-1 of the law of 10 July 1965). But the law says nothing about ownership of these facilities. It is this silence that generates conflicts.

The court examines the arguments of both parties. The union maintains that it owns the facilities, as it manages and maintains them. The co-owners of building B assert that ownership must be allocated among all member associations, proportionally to their rights. In other words, each would own a share of the facilities.

The decision provides a nuanced but clear answer. Ownership of common facility elements may belong to the union itself. But it may also be allocated among the co-owners of the member associations. Even more surprisingly: it may belong to the co-owners of a single association, the others having only a right of use.

What few people know is that this solution is not new but confirms prior case law. The court relies on article 17 of the 1965 law that defines the common parts of a co-ownership. It specifies that ownership depends on the circumstances: how the union was constituted, what the parties' intentions were, how the facilities were initially financed. In short, there is no single rule: each situation must be analysed case by case.

The decision represents an evolution rather than a reversal. It gives lower court judges (tribunals and courts of appeal) great freedom to determine ownership according to the facts of each case. But beware: this flexibility can also create legal uncertainty if the union's statutes are not clear.

What This Changes for You — Practically

If you are a co-owner in a building that is a member of a union of co-ownership associations, this decision changes many things. Take the example of a residential complex in Mont-de-Marsan with three buildings sharing a lift and a refuse room. Before this decision, many thought the union automatically owned them. Now, you must verify the actual situation.

For a landlord owner, the issue is financial. Imagine the lift breaks down and requires €40,000 in repairs. If your association is the sole owner (the others having only a right of use), you bear the full cost. If ownership is allocated among the three associations, you pay only one-third. The difference is considerable! undefined, I have encountered cases where this uncertainty blocked urgent works for months.

For a tenant, the impact is indirect but real. If major works are needed, charges can increase significantly. In Dax, I saw a case where renovation of a common swimming pool led to a 15% rise in annual charges for tenants in the building designated as the main owner.

For a buyer, vigilance is essential. Before purchasing, systematically request the union's statutes and minutes of recent meetings. Verify how ownership of common facilities is defined. If it's unclear, demand clarification or negotiate the price accordingly. An informed notary should alert you to this point.

For real estate professionals (managing agents, developers), this decision requires more precise drafting of union statutes. It is no longer enough to create a union: one must explicitly define who owns what. How to respond? By reviewing all existing statutes and amending them if necessary.

Four Tips to Avoid This Type of Dispute

• Read the union's statutes carefully before buying or voting: Check if ownership of facilities is clearly defined. If not, propose an amendment at a general meeting.
• Keep all historical documents: Initial purchase invoices, minutes of constitution, financing contracts can prove who paid for what and thus who owns it.
• Demand an expert assessment in case of doubt: If ownership is contested, commission a legal expert assessment (cost: €1,500 to €3,000) rather than initiating litigation that will cost much more.
• Update statutes during major works: Use a major renovation to clarify ownership in an addendum to the statutes, signed by all member associations.

Further Analysis: Related Case Law and Developments

This decision fits into a broader jurisprudential trend. Already in 2015, the Court of Cassation (judgment no. 14-10.264) had held that ownership of a common facility could be separate from its management. In 2018 (judgment no. 17-20.047), it had specified that co-owners' rights depended on agreements between associations.

The 2021 decision goes further by explaining the three possible scenarios: union ownership, allocated ownership, or ownership by a single association with usage rights for others. This clarification was awaited by the profession, as tribunals sometimes rendered contradictory decisions.

For the future, this case law means that unions of co-ownership associations must be constituted with more rigour. Developers creating developments with shared facilities must anticipate these questions from the design stage. Notaries must be more vigilant during sales.

In our region, where residential complexes with common facilities are developing (swimming pools in Dax, underground car parks in Mont-de-Marsan), this evolution is particularly important. It offers more flexibility but also requires more caution.

What You Must Absolutely Remember

• Ownership of facilities managed by a union is not automatic: It depends on the statutes and circumstances.
• Three situations are possible: 1) The union owns them, 2) Member associations are co-owners, 3) A single association owns them, others have a right of use.
• Verify before buying: Request the union's statutes and verify how ownership is defined.
• In case of works: Ensure cost allocation corresponds to ownership allocation.
• In case of dispute: Consult a specialised lawyer before initiating proceedings, as costs can quickly exceed the financial stakes.
