Clause of Inalienability in Co-ownership: The Court of Cassation Upholds Restrictions on the Division of Lots

Imagine: you own a flat in Mérignac, with a small maid's room on the top floor. You wish to sell this room separately to free up some cash. But the co-ownership regulations forbid it, except with the permission of the general meeting. What to do? This question is often asked, especially in older buildings where ancillary lots are common.

The French Court of Cassation, in a judgment of 10 March 1981, ruled: a clause that prohibits the alienation of part of a lot (for example, selling a maid's room without the apartment) may be lawful if it is justified by the purpose of the building and the proper use of common areas. In other words, co-owners cannot freely divide their lots as they wish.

But what exactly does this change for you? This decision, although dating from 1981, remains a reference for current disputes. It reminds us that the co-ownership regulations can limit the right of ownership to preserve the harmony of the building. Let's delve into the details.

The Facts: A Story That Happens Every Day

In this case, the co-owners of a small building (only a few lots) contested a clause in the co-ownership regulations. This clause prohibited selling a maid's room separately from the main apartment, except by decision of the general meeting. In short, one could not 'detach' part of a lot to sell it to an independent third party.

An owner, whom we will call Mr. X, wished to sell his maid's room located under the eaves to a neighbour. But the syndic opposed it, invoking the regulations. Mr. X then sued the co-owners' association to have this clause annulled, arguing that it was an excessive infringement on his right of ownership.

The Tribunal de Grande Instance of Bordeaux dismissed his claim. Mr. X appealed, but the Bordeaux Court of Appeal upheld the judgment. He then appealed to the Court of Cassation. The Court of Cassation dismissed his appeal, thereby validating the contested clause. The judges held that, given the small size of the co-ownership, the purpose of the building did not allow indefinite subdivision of lots, and that the absence of ancillary lots (such as maid's rooms) would lead to clutter of common areas and hinder the normal use of the building.

The Reasoning of the Court — Dissected

The Court of Cassation relied on Article 9 of the Law of 10 July 1965 (governing co-ownership) and Article 1134 of the Civil Code (now 1103, which enshrines the binding force of contracts). In essence, it said: the co-ownership regulations are a contract freely accepted by all co-owners. It may therefore contain restrictions on the right of ownership, provided they are not abusive.

In this case, the clause was justified: the co-ownership was small (few lots), so too much division risked multiplying owners and harming management. Moreover, the maid's rooms often served as storage or staff accommodation; without them, common areas would be cluttered with bicycles, pushchairs, etc. The judges thus considered that the clause pursued a legitimate collective interest.

What few people know is that the Court of Cassation also noted that the general meeting could derogate from this prohibition by a special decision. Thus, the clause was not absolute, but merely conditional. This weighed heavily in the balance: co-owners retained the possibility of selling part of their lot, provided they obtained the collective's agreement.

Caution, however: this solution is not automatic for all co-ownerships. The Court emphasised the particular circumstances (small size, purpose of the building). In a large co-ownership, a similar clause could be deemed abusive if not justified.

What This Changes for You — Concretely

If you are the owner of a lot in a small co-ownership and wish to divide your lot, first check your co-ownership regulations. A partial inalienability clause may be valid if motivated by the purpose of the building. For example, in Arcachon, in a seaside residence of 10 lots, the regulations may prohibit selling a parking space separately from the apartment to avoid multiplying co-owners and harming tranquility.

For buyers: before buying a 'detached' maid's room or garage, ensure that the sale was authorised by the general meeting. Otherwise, the sale could be annulled for violation of the co-ownership regulations. undefined, I have come across cases where buyers purchased a separate cellar, only to discover that the regulations prohibited division. Result: long and costly proceedings.

For co-owners who want to enforce the regulations: if a neighbour sells part of their lot without authorisation, you can take legal action to have the violation declared and claim damages. The time limit to act is 10 years from the sale (acquisitive prescription), but it is better to react quickly.

Concrete example: in Mérignac, an owner wished to sell his maid's room for €15,000. The general meeting refused because the regulations clause prohibited it. He had to abandon the sale for lack of agreement. He could have challenged the clause, but the cost of proceedings (lawyer, expert) can reach €3,000 to €5,000, with no guarantee of success.

Four Tips to Avoid This Type of Dispute

• Read your co-ownership regulations before any partial sale. Do not rely on what the neighbour or estate agent says. The regulations are an official document binding on everyone. Request a copy from your syndic.
• Seek the opinion of the general meeting before incurring costs. If the regulations prohibit division, you can request a derogation. Convene a general meeting and put the question on the agenda. If the AG refuses, you will know where you stand.
• Consult a lawyer specialising in property law to analyse the clause. A professional can tell you whether the restriction is legitimate or abusive. For example, a clause that prohibits any alienation without exception could be deemed excessive.
• In the event of a dispute, opt for mediation before litigation. Legal costs are high and delays long. Mediation can lead to an agreement (e.g., sale to an existing co-owner).

Before this 1981 judgment, the Court of Cassation was rather favourable to the freedom to sell one's property. For example, in a judgment of 9 July 1970, it annulled a clause prohibiting the sale of a lot to a non-co-owner. But here, the Court made a distinction: the clause did not concern the identity of the buyer, but the division of the lot itself, and it was justified by practical imperatives.

Since then, the trend has been to respect the co-ownership regulations, as long as they are not contrary to public policy. Courts check whether the restriction is proportionate to the aim pursued. Thus, in a judgment of 2015 (Civ. 3e, 4 June 2015, No. 14-16.123), the Court upheld a clause prohibiting short-term rentals because it protected the building's tranquility.

For the future, one can expect judges to become increasingly strict on the justification of clauses. A regulation that prohibits any division without a valid reason would risk being struck down. On the other hand, a clause motivated by the preservation of common areas or the management of the co-ownership has good chances of being upheld.

Frequently Asked Questions

Can I sell my maid's room separately if the regulations forbid it? No, unless the general meeting authorises it by a special decision. Otherwise, the sale could be annulled.

What if my neighbour sells part of their lot without authorisation? You can bring the matter before the judicial court to have the violation of the regulations declared and claim damages. Consult a lawyer promptly.

Can a clause of inalienability be annulled? Yes, if it is abusive, for example if it prohibits any sale without justification. But this is rare: judges tend to favour compliance with the regulations.

What are the time limits to act? The action to annul a sale contrary to the regulations is subject to a 10-year limitation period from the sale. For a claim for damages, it is 5 years.

How much does a legal proceeding cost? Expect between €2,000 and €5,000 in lawyer's fees, plus possible expert fees (€1,000 to €3,000). Mediation is cheaper (€500 to €1,500).
