Imagine: you sell a house in Hérouville-Saint-Clair for €150,000. A few months later, you discover it was worth €300,000. A dishonest buyer? A simple valuation error? The law offers you a weapon: the action for rescission for lesion of more than seven-twelfths. But be careful, if you choose the wrong procedure, you could lose everything. This is what the Court of Cassation reminded in a judgment of 21 May 1979 (No. 78-10.578), still relevant today. Analysis.
You have sold a property at a price you now consider derisory. You want to cancel the sale. Two routes are open to you: an action for nullity (for example, for defect of consent) or an action for rescission for lesion (where the price is less than 5/12 of the real value). But the Court of Cassation has ruled: these two actions do not have the same objectives. One annuls the sale, the other challenges it on price. And if you choose the wrong one at first instance, you cannot change your mind on appeal.
What happened in this case? A seller, owner of an agricultural property, sued the buyer. He initially sought nullity of the sale. On appeal, he changed strategy and claimed rescission for lesion. Too late, said the Court. Why? Because rescission can be blocked by an offer from the buyer to pay the additional price, which is not possible with nullity. The purposes are different, so the new claim on appeal is inadmissible. A lesson for every seller.
The Facts: A Story That Happens Every Day
Mr. X, owner of a rural property in Hérouville-Saint-Clair, signed a preliminary sale agreement with the company Calmes. The deed covered buildings and part of the land. But soon a dispute arose: the seller believed the agreement only covered buildings, while the buyer claimed it also included the land. The sum involved? Several tens of thousands of euros at the time. Mr. X sued Calmes, seeking nullity of the sale for mistake as to the object of the contract. He argued that his consent was vitiated.
The court of first instance examined the pleadings. Calmes acknowledged in its submissions that the agreement covered both buildings and land. But the seller maintained his position. The judgment rendered is unknown, but it seems nullity was not granted. Dissatisfied, Mr. X appealed. And then, surprise: he no longer sought nullity, but rescission of the sale for lesion of more than seven-twelfths. He argued that the price was less than 5/12 of the real value of the property. A strategic change of tack.
The Court of Appeal had to decide. Could it consider this new claim? The lower court judges questioned this. The buyer, Calmes, raised a procedural bar: the claim for rescission was new on appeal and therefore inadmissible. The seller retorted that both actions pursued the same goal: to undo the sale. But the Court of Cassation, seised of the matter, would rule definitively. The case, originating from Hérouville-Saint-Clair, reached the highest court. A classic judicial journey, but the outcome has immediate practical consequences for all sellers.
The Reasoning of the Court — Analysed
The Court of Cassation, in its judgment of 21 May 1979, was very clear: the action for rescission for lesion and the action for nullity do not tend to the same ends. Why? Because rescission can be blocked by an offer from the buyer to pay an additional price (Article 1681 of the Civil Code, still in force). In other words, if the price is too low, the buyer can save the sale by paying the difference. Nothing similar for nullity, which retroactively annuls the contract. The legal effects are therefore different.
The legal basis for rescission is Article 1674 of the Civil Code: "If the seller has suffered a lesion of more than seven-twelfths in the price of immovable property, he has the right to demand rescission of the sale." Concretely, this means that if the sale price is less than 5/12 of the real value of the property, the seller can demand either annulment of the sale or a supplementary price. The buyer, for his part, can always avoid annulment by offering to pay the difference (Article 1681). This mechanism distinguishes rescission from nullity.
In this case, the seller initially chose nullity. On appeal, he wanted to switch to rescission. The Court of Cassation said no: a new claim on appeal is inadmissible if it is not ancillary, consequential, or complementary to the initial claim (Article 565 of the Code of Civil Procedure, old, but the principle still applies). Here, the two actions are not connected. The seller should have, from the outset, formulated both claims in the alternative. He did not, and he lost. The judges therefore confirmed the inadmissibility. A lesson in judicial strategy: choose your action carefully, or cumulate them from the summons.
What This Means for You — Practically
If you are a seller of property and believe you have suffered a lesion on the price, you need to know which action to bring. The action for nullity (for defect of consent, mistake, fraud) and the action for rescission for lesion are two distinct routes. Do not confuse them. If you seek nullity at first instance, you cannot, on appeal, seek rescission. You will be inadmissible. So, what to do?
Take a concrete example: you sell a house in Ifs for €200,000. An expert estimates its real value at €350,000. The lesion is €150,000, i.e., more than 7/12 (since €200,000 < 5/12 of €350,000 = €145,833). You can seek rescission. But if you first sought nullity for mistake as to area (Carrez law), you cannot later seek rescission on appeal. You must, from the summons, formulate both claims, as primary and alternative.
For the buyer, this decision is rather protective. It prevents them from being "surprised" by a change of basis during proceedings. The buyer can also, if they fear rescission, offer to pay the supplementary price to save the sale. But be careful: this offer must be made before judgment is rendered. If you are a buyer and receive a summons for nullity, you can rest easy: the seller cannot, on appeal, seek rescission. However, if the summons mentions rescission, prepare to negotiate or prove the price was fair.
Four Tips to Avoid This Type of Dispute
- Have the property valued by an expert before the sale. Do not rely solely on your intuition. A professional valuation (agent, notary, expert) gives you a basis to set the price and avoid lesion. Expect to pay between €200 and €500 for an expert opinion, an investment that can save you years of litigation.
- Draft a precise preliminary sale agreement. The object of the contract (buildings, land, outbuildings) must be clearly described. In the 1979 case, the dispute centred on the extent of the property sold. A vague description is an open door to challenges. Use a notary or lawyer for drafting.
- Keep all documents relating to the value of the property. Valuations, surveys, photos, correspondence with the buyer. In case of dispute, these pieces of evidence are essential to demonstrate that the price was in line with the market or, conversely, that there was a lesion.
- If in doubt, cumulate the legal actions. If you think you have suffered a lesion, seek both nullity (if you have a defect of consent) and, in the alternative, rescission for lesion. This way, you will not be trapped in a dead end. Consult a specialist lawyer before issuing proceedings.
Further Reading: Related Case Law and Developments
The 1979 decision is part of a consistent line of the Court of Cassation. Already in a judgment of 7 February 1973 (No. 71-13.466), the Court had held that the action for rescission and the action for nullity for mistake were distinct. More recently, in a judgment of 13 September 2017 (No. 16-19.799), the Court reiterated that rescission can only be sought if the lesion exceeds seven-twelfths, and that the buyer can always avoid it by offering the supplementary price. The case law has thus been stable for nearly 50 years.
What is evolving, however, is the practice of the courts. Increasingly, sellers, aided by lawyers, cumulate the grounds in their summons. And buyers, for their part, are more vigilant about the purchase price. The trend is towards securing transactions. If you are selling, anticipate: a preliminary expert opinion and legal advice will save you many troubles. And if you are buying, be wary of offers that are too good: they could hide a future action for rescission.
Summary and Next Steps
FAQ:
- What is rescission for lesion? It is a legal action allowing a seller to obtain the annulment of a property sale or a supplementary price if the property was sold at a price less than 5/12 of its real value.
- Can I seek both nullity and rescission? Yes, but you must do so from the summons, as primary and alternative claims. Otherwise, you cannot change on appeal.
- What are the time limits to act? The action for rescission must be brought within 2 years of the sale (Article 1676 of the Civil Code). After that deadline, you lose all rights.
- What if I am a buyer and the seller seeks rescission? You can offer to pay the supplementary price (the difference between the price paid and 5/12 of the real value) to keep the property. This offer must be made before judgment.
- Is the 1979 decision still applicable? Yes, it is still cited by courts. It is authoritative on the distinction between nullity and rescission.
