Latent Defects in Shared Ownership: The Managing Agent May Bring Legal Proceedings on Behalf of the Owners’ Association

Imagine: you have just bought a flat in Roubaix, in a charming 1960s shared ownership block. Everything seems perfect until, six months later, cracks appear in the load-bearing walls. Damp seeps in, ceilings sag. The diagnosis is clear: the building suffers from latent defects, those serious hidden defects that the seller should have disclosed. Who can take action? Each individual co-owner? The owners’ association? The managing agent?

This question, though crucial, long divided the courts. The answer came from the Court of Cassation on 18 May 1971, in a landmark judgment that clarified the powers of the managing agent. In other words, can the managing agent, without authorisation from the general meeting, bring legal proceedings on behalf of the owners’ association? The answer is yes, subject to certain conditions.

In this article, I will explain this judgment simply, what it changes for you — whether you are an owner, tenant or property professional — and how to avoid finding yourself in a complex situation. Because in Tourcoing as elsewhere, it is better to know your rights before the walls crack.

The facts: a story that happens every day

In the early 1970s, a property developer sold the flats in a new building in Roubaix as separate lots. The purchasers moved in, delighted. But soon, defects appeared: water ingress, sealing defects, structural cracks. The building was affected by latent defects — those hidden defects not apparent at the time of purchase that render the building unfit for its intended purpose or so diminish its use that the buyer would not have acquired it (or would have paid less) had they known of them.

The managing agent of the shared ownership, a certain Mr Ibartz, decided to act. He brought proceedings against the seller, on behalf of the owners’ association, to obtain compensation for latent defects. But the seller challenged the admissibility of the action: according to him, the managing agent had no power to bring such proceedings without express authorisation from the general meeting of co-owners. The Court of Appeal agreed with him: it declared the action inadmissible, on the ground that the managing agent had exceeded his powers.

The managing agent appealed to the Court of Cassation. The question was clear: can a managing agent alone represent the owners’ association in court for an action for latent defects? The Supreme Court judges would decide.

The reasoning of the court — explained

The Court of Cassation set aside the appeal judgment. Its reasoning relied on two essential texts, now codified in Articles 14 and 18 of the Law of 10 July 1965 on shared ownership (here simplified).

First text (former Article 15 of the 1965 Law, now Article 14): the owners’ association has standing to bring proceedings to safeguard rights relating to the building. In other words, the owners’ association may sue to defend collective interests — such as compensation for latent defects affecting common parts or the building as a whole.

Second text (former Article 18, now Article 18): the managing agent is responsible for representing the owners’ association in all civil acts and in legal proceedings. This means the managing agent is the legal representative of the owners’ association, without needing special authorisation for each court action, provided that the action falls within the scope of safeguarding the rights to the building.

In this case, the Court held that the action for latent defects was precisely aimed at protecting the co-owners’ rights to the building. The managing agent, by acting, was merely exercising his role. The Court of Appeal had therefore been wrong to limit his powers. This was not a reversal of precedent, but a confirmation of the principles of shared ownership: the managing agent is the guardian of collective interests.

However, note: this judgment does not give the managing agent a blank cheque. He must act within the limits of his functions, and the general meeting remains sovereign to approve or not his actions. But for urgent actions or those necessary for the preservation of the building, the managing agent may act alone.

What this changes for you — practically

Whether you are an owner in a shared ownership in Tourcoing, a tenant of a flat in Roubaix, or a property professional, this decision has practical implications.

For co-owners: If your building suffers from latent defects (cracks, water ingress, insulation defects), you do not need to wait for a general meeting to act. The managing agent can bring an action quickly, which is crucial because limitation periods (5 years from discovery of the defect) are often short. undefined, I have seen cases where co-owners lost their right to compensation because the managing agent delayed acting, for lack of authorisation. Today, the managing agent can go to court without waiting.

For purchasers: When you buy a lot in a shared ownership, check whether any legal proceedings are ongoing. The managing agent may have already brought an action for latent defects: you could benefit from the compensation if you become a co-owner. Conversely, if the managing agent has not acted, you can ask the general meeting to authorise it — or pursue the seller individually, but that is more complex.

For sellers and developers: This decision exposes you to collective actions. A single latent defect can trigger proceedings brought by the managing agent on behalf of all co-owners. Concrete example: a developer sells a building in Tourcoing; five years later, sealing defects appear. The managing agent brings an action, and the developer must compensate all co-owners, totalling several hundred thousand euros. It is better to take out appropriate professional liability insurance.

For tenants: You are not directly concerned by the owners’ association’s action, but if latent defects make the dwelling unfit for habitation, you can take action against your landlord (owner) for breach of the obligation to deliver a decent dwelling. The managing agent, for his part, deals with the common parts.

Four tips to avoid this type of dispute

• Have a thorough technical survey carried out before purchase: Before signing a preliminary contract, call in a building expert to inspect the building (common and private parts). In Roubaix, expect to pay between €800 and €1,500 for a full survey, an investment that can save you years of litigation.
• Check the minutes of general meetings: When buying a lot, ask for the minutes of the last five years. They may mention works, defects or legal proceedings. A latent defect is often preceded by warning signs.
• Do not wait to report a problem: If you notice a crack, water ingress or any other defect, immediately notify the managing agent in writing (recorded delivery with acknowledgement of receipt). The limitation period starts from the date of discovery of the defect, not from its appearance.
• Consult a lawyer lawyer at the first signs: A property lawyer can assess the situation, determine whether the defect is latent (and not apparent) and advise on the strategy to adopt. A quick 30-minute consultation (€45 at my firm) can enlighten you on your rights and the deadlines to respect.

Further reading: related case law and developments

The 1971 judgment is part of a line of decisions reinforcing the powers of the managing agent. For example, a Court of Cassation judgment of 12 January 1999 (No. 96-22.157) held that the managing agent may bring proceedings to stop neighbourhood disturbances affecting the shared ownership, without authorisation from the general meeting. Similarly, a judgment of 8 March 2005 (No. 03-17.372) extended this power to actions for contractual liability against the developer.

The trend is therefore clear: the courts recognise a broad capacity for the managing agent to act to protect the building, provided the action is in the collective interest. Note however: if the action goes beyond mere safeguarding (for example, an action to annul a sale contract), the general meeting must authorise it. But for latent defects, the managing agent has free rein.

For the future, case law continues to evolve. Recently, the Court of Cassation clarified that the managing agent may also bring interim proceedings (urgent procedure) to obtain an expert report before any trial. This allows evidence to be preserved and avoids limitation.

Checklist before acting

1. Is it truly a latent defect? The defect must be serious, not apparent at the time of purchase, and pre-existing the sale. Simple lack of maintenance is not enough.
2. Am I within the time limit? The action for latent defects is barred after 5 years from discovery of the defect. In shared ownership, the date of discovery is often the date of the general meeting minutes recording the disorder.
3. Has the managing agent acted? Check with your managing agent whether proceedings have been brought. If not, ask him to act or request authorisation from the general meeting.
4. Which court? The action is brought before the judicial court of the location of the building. In Roubaix, it is the judicial court of Lille. Legal fees vary (€1,500 to €5,000 for a standard procedure), but may be recovered if you win.
5. What evidence? Gather all documents: sale deed, technical survey, photos, correspondence, repair estimates. A court-ordered expert report is often appointed to determine the origin and extent of the defects.
