In equine law, ignoring a known health defect when selling a horse exposes the seller to cancellation for fraud and to damages. Decryption of the information obligation.
In equine law, the silence of the seller on the state of health of a horse does not arise from commercial skill, but from fraud. A series of recent decisions reminds us that the sanction can go as far as the pure and simple cancellation of the sale, accompanied by damages. Deciphering a rule that everyone in the equine industry should master.
The case has warning value. In November 2024, a court annuls the sale of a horse and orders the sellers to reimburse the price, to compensate the buyer for the costs incurred… and to repair her moral damage. Their fault: having concealed a pathology that they knew about. The detail that changes everything? One was a farrier, the other a rider and trainer. Horse professionals, therefore, presumed to know what they were selling.
This decision illustrates a reality of the equine market: among enthusiasts, the reflex to present the horse “in its best light” is common, but it has a strict legal limit. This limit is the pre-contractual obligation of information, and its most dangerous version for the seller: fraudulent reluctance.
Silence can be a mistake
Since the reform of contract law in 2016, article 1112-1 of the Civil Code establishes a clear principle: anyone who knows information whose importance is decisive for the consent of the other must inform him of it, as long as the latter is legitimately unaware of this information or trusts his co-contractor.
Applied to the sale of an equine, this means that a seller cannot let a buyer sign in ignorance of an element that he knows is decisive: a history of lameness, a locomotor pathology, a behavioral disorder, a heavy medical history. The text even specifies that this obligation cannot be waived by contract: a clause which purports to cancel it is deemed unwritten.
When this silence is intentional – when we remain silent to obtain the signature – we slip into fraud. Article 1137 of the Civil Code expressly equates “the intentional concealment by one of the contracting parties of information of which he knows the decisive nature for the other party” as a fraudulent maneuver. This is fraudulent reticence: not an active lie, but a withholding of information.
The consequence is serious. Fraud is a defect in consent: it allows the buyer to request the cancellation of the sale (nullity), accompanied by damages. The seller then does not simply take back his horse: he reimburses the price, the boarding, transport or care costs incurred by the buyer, and can be condemned for the damage suffered. In the aforementioned case, the judge even recognized moral damage, due to the impossibility of participating in competitions and the attachment to the animal.
The status of horse professional aggravates the risk
The most instructive point is the quality of the games. In the Châtellerault decision, the judge held the sellers responsible precisely because their jobs gave them “particular knowledge” of the state of health of the horse. Their professionalism reinforced their obligation to provide information.
The lesson applies to all players in the industry: farrier, trainer, horse dealer, breeder, coach or professional rider. The more competent the seller is regarding the horse he is selling, the less he will be able to plead ignorance of a defect. The asymmetry of knowledge between a knower and a lay buyer is exactly what the law seeks to correct. Selling “knowingly” without sharing this knowledge means exposing yourself to seeing the sale reclassified as fraud.
But the cover-up must be proven
The severity of the system has a counterpart: it is still necessary to demonstrate intentional concealment. Another decision, rendered in November 2024 by the Bordeaux judicial court, nuanced the picture. A rider had bought a mare from her coach intended for the show jumping competition, then accused him of having hidden a medical history (an MRI and previous episodes of lameness) and of having sold her as fit for the sport.
The court rejected all of his requests. Reason: a judicial expertise, conducted adversarially and not formally contested, established no incapacity at the time of the sale. The antecedents cited reflected a one-off trauma, not incompatible with the pursuit of a sporting career — not a hidden defect. And certificates from riders are not enough to make up for the lack of proof.
The lesson for the buyer is twofold. First, fraud cannot be presumed: it is necessary to prove both that the seller knew and that he knowingly kept silent. Then, the forensic veterinary expertise remains the centerpiece of any equine dispute: its probative force is very difficult to overturn once it has been conducted according to the rules.
What to remember, on the seller’s and buyer’s side
Prudence for the seller is to document what they have revealed. Before selling a horse, it is better to record in writing the history, care, injuries or limitations known and brought to the attention of the buyer – an email, an annex to the sales contract, the provision of the health record and veterinary reports. Assumed transparency is the best insurance against an action for nullity several months after the sale.
For the buyer, the lesson is the opposite: provide proof of what was told to him – or you – at the time of purchase, and not to skip a veterinary visit to purchase. This examination, ideally complete and documented, will weigh heavily in the event of litigation, whether it involves establishing a defect or, on the contrary, the real condition of the horse on the day of the sale.
There remains a simple rule, valid for the entire industry: in the sale of a horse, strategic silence on what matters is not a negotiated advantage. It’s a legal risk that can, months later, cause the animal — and the check — to return to its starting point.
