Imagine you own an apartment in Antibes, facing the sea. You've just bought this rare gem after months of searching, but a few weeks after moving in, you discover water infiltration in the living room. The seller had assured you everything was in perfect condition. What should you do? Should you settle for requesting repairs for the apparent damage, or could you also claim damages for moral prejudice?
This situation, unfortunately all too common on the French Riviera where old properties coexist with new constructions, raises a fundamental question: how far can you go with your judicial claims once the dispute has been initiated? Many property owners in Antibes or Le Cannet hesitate to resort to the courts, fearing they might get locked into rigid procedures where they could no longer adapt their claims.
The Court of Cassation, in its decision of 19 March 2025, provides a clear and reassuring answer. It confirms that when a dispute moves from the summary proceedings judge (who rules urgently) to the judge ruling on the merits (who examines the case in its entirety), the parties can present new claims. A major procedural evolution that deserves attention.
The Facts: A Story That Happens Every Day
Take the example of Mr. Dubois, owner of a villa in Antibes that he bought a few years ago. Like many purchasers on the French Riviera, he was seduced by the charm of the old and the promise of a trouble-free property. But a few months after the purchase, he discovers recurring damp problems in the cellar, then cracks appear on the load-bearing walls.
Mr. Dubois suspects latent defects (serious defects in the property that were not apparent at the time of sale and render the property unfit for its intended use). He decides to act quickly and seizes the summary proceedings judge to urgently obtain protective measures: an expert assessment to evaluate the extent of the damage and temporary works to secure the villa.
The summary proceedings judge, noting the urgency, orders the expert assessment but refers the case to the judge ruling on the merits to examine the core of the dispute. It is at this point that the situation becomes interesting. Before the judge on the merits, Mr. Dubois doesn't just repeat his initial claims. He introduces new claims: not only the repair of the latent defects, but also damages for the moral prejudice suffered, and even the rescission of the sale (cancellation of the sale with refund of the price).
The seller contests these new claims, arguing that they were not presented before the summary proceedings judge and therefore should not be admissible. This is precisely the point that the Court of Cassation will decide.
The Court's Reasoning — Analysed
The Court of Cassation, in its judgment of 19 March 2025, recalls the legal foundations of this procedure. It relies on Article 873-1 of the Code of Civil Procedure (which organises the referral of a case from the summary proceedings judge to the judge ruling on the merits) and on Article 70 of the same code (which defines the different categories of claims that parties can present).
In simple terms, the judges explain that when the summary proceedings judge refers a case to the judge on the merits, it is not a simple transfer of file. It is a new procedural phase where the parties can enrich their claims. In other words, the appearance before the summary proceedings judge is only a preliminary stage, often urgent, that does not lock down the debate.
The Court specifies that three types of claims can be introduced at this stage: incidental claims (which add to the initial claims), additional claims (which complete or modify existing claims) and counterclaims (where the defendant becomes the claimant in turn). In Mr. Dubois's case, his claim for damages for moral prejudice was an incidental claim, while his claim for rescission of the sale was an additional claim.
What few people know is that this position is not entirely new. The case law (the body of court decisions) had already evolved in this direction in recent years. But this Court of Cassation decision confirms and clarifies it, putting an end to uncertainties that may still have existed in some courts.
The Court rejects the seller's argument that the new claims would be inadmissible because they were not presented earlier. It recalls that the procedure before the summary proceedings judge is an urgent procedure, where the parties do not always have the time or means to develop all their claims. The judge on the merits, on the other hand, has the mission to examine the case in all its breadth and from all angles.
What This Changes for You — Practically
If you are a landlord in Antibes, this decision concerns you directly. Imagine you rent out an apartment and your tenant reports recurring electrical problems. You seize the summary proceedings judge to establish the urgency and order minimal repairs. But before the judge on the merits, you could also request termination of the lease for unsanitary conditions, or damages if the tenant delayed reporting the problems.
For purchasers, like our Mr. Dubois from Antibes, this is a real breath of fresh air. You are no longer obliged to anticipate everything from the moment you seize the summary proceedings judge. You can first secure the situation (stop an immediate danger, have damage recorded before it worsens), then develop your claims once before the judge on the merits. undefined, I have encountered cases where purchasers had given up on certain claims for fear of complicating the initial procedure. This decision gives them more room for manoeuvre.
Take a concrete example in Le Cannet. A couple buys a house for €800,000. They discover after purchase that there are termites in the roof structure, requiring €50,000 of works. They seize the summary proceedings judge to establish the urgency and order safety measures. Before the judge on the merits, they will be able to not only request that the seller bear the cost of the works (based on the latent defects guarantee), but also compensation for loss of amenity (loss of enjoyment of the property during the works) and even, if the defects are particularly serious, rescission of the sale with full refund of the price.
Be careful however: this procedural flexibility should not encourage you to neglect the summary proceedings phase. The summary proceedings judge remains a crucial stage, particularly for recording elements that might disappear (like traces of infiltration after a dry period) or for obtaining protective measures (like the appointment of an expert). But you now know that this phase does not lock down your entire judicial strategy.
Four Tips to Avoid This Type of Dispute
- Always have a thorough survey done before purchase: in Antibes as elsewhere, don't rely on appearances. Engage an independent expert to check the condition of the roof, foundations, electricity, plumbing. A survey costing €500 to €1,000 can save you disputes costing tens of thousands of euros.
- Document exchanges with the seller precisely: keep all emails, text messages, and notes of conversations where the seller makes statements about the property's condition. In case of latent defects, these elements could prove that they misled you.
- Act quickly as soon as you discover a problem: the latent defects guarantee is subject to a two-year limitation period from discovery of the defect (Article 1648 of the Civil Code). As soon as you notice a defect, have it recorded by a bailiff or expert, and put the seller on notice by registered letter with acknowledgement of receipt.
- Consult a lawyer lawyer before resorting to the courts: even if you're considering summary proceedings first, a lawyer can help you anticipate claims you might formulate later before the judge on the merits, and prepare your arguments from the outset.

Further Analysis: Related Case Law and Developments
This Court of Cassation decision fits into a broader evolution of case law towards greater procedural flexibility. Already in 2018, the Court had rendered a judgment (No. 17-10.305) that admitted the possibility of presenting new claims before the judge on the merits after referral by the summary proceedings judge, but in a slightly different context.
What is new with the 2025 judgment is the clarity and firmness of the reasoning. The Court doesn't just apply a procedural rule: it recalls the very philosophy of the distinction between summary proceedings and merits. Summary proceedings are about urgency, the temporary, the provisional. The merits are about the definitive, the complete, the exhaustive. Allowing parties to enrich their claims between the two phases respects this logic.
This trend is particularly important in the real estate field, where disputes are often complex and multifaceted. A construction problem can lead to both material damage, moral prejudice, loss of property value, and sometimes even health consequences for occupants. Requiring all these claims to be formulated from the summary proceedings phase would be unrealistic and contrary to equity.
For the future, we can expect this case law to also apply to other areas of law, like commercial law or consumer law. But it is in real estate that it will likely have the most immediate and concrete impact.
Key Points to Remember
1. The summary proceedings judge and the judge on the merits are two distinct stages: the first rules urgently on provisional measures, the second examines the case in its entirety.
2. You can present new claims before the judge on the merits: even if they weren't raised before the summary proceedings judge, your incidental, additional or counterclaims are admissible.
3. The latent defects guarantee remains subject to strict time limits: you have two years from discovery of the defect to act, and this action is subject to a ten-year limitation period from the date of sale.
4. Document everything and act quickly: in case of problems, have it recorded by a professional, put the seller on notice, and keep all evidence.
5. Consult a lawyer at the first signs of dispute: a real estate lawyer can guide you in the procedural strategy best suited to your situation.
