Latent Defect: The Time Limit Runs from Discovery of the Defect

You have just bought a used car in Belfort. The first few kilometres go well, but after a few weeks, a suspicious noise appears. You take it to a mechanic, who reveals a deformed side member and dangerous play in the steering. The seller assured you everything was in order. What should you do? And above all, do you still have time to act?

The question every owner faced with a latent defect asks is: when does the time limit for taking legal action start? Is it the day of the sale, the day the defect appears, or the day you actually become aware of it? The answer is not trivial: it can mean the difference between compensation and being time-barred.

It is precisely on this point that the Court of Cassation ruled in a judgment of 21 December 1971, still relevant today. The judges decided that the time limit for the redhibitory action (an action to obtain the annulment of the sale or a reduction in price) only starts to run from the moment the buyer discovers the defect, and not from the date of sale. An essential protection for consumers.

The facts: a story that happens every day

In 1968, a man named Roy bought a used car. A few months later, he noticed serious anomalies: a very deformed side member and significant play in the front axle control. These defects made the vehicle dangerous, but the seller had never informed him. Roy called in an automobile expert, who filed his report on 8 January 1969, revealing the extent of the defects. Without delay, Roy sued the seller on 23 January 1969, only 15 days after the report, to obtain the avoidance of the sale (annulment) on the grounds of latent defects.

The seller contested: according to him, the action was late. Article 1648 of the Civil Code (now codified in Article 1648, first paragraph) requires the buyer to act "within a short time limit" from the discovery of the defect. The seller argued that Roy should have acted from the first symptoms, not after the expert report. But the lower court judges (the Court of Appeal) ruled in favour of Roy, and the Court of Cassation upheld this judgment in 1971.

The story of Mr Roy could have taken place in Danjoutin: a trusting buyer, an unscrupulous seller, and a car that hides its wounds. The courts of Belfort or Montbéliard would no doubt have ruled the same way, because the solution adopted by the Court of Cassation applies uniformly throughout the country.

The reasoning of the court — dissected

The Court of Cassation ruled on two essential points. First, it confirmed that the lower courts have sole discretion to determine whether the anomalies constitute latent defects within the meaning of Article 1641 of the Civil Code. This article provides that the seller is liable for hidden defects that render the thing unfit for its use or so diminish its use that the buyer would not have acquired it (or would have given only a lower price) had they known of them. In this case, a car with a deformed side member and faulty steering is clearly dangerous and therefore unfit for its purpose.

Next, and this is the crucial point, the High Court recalled that the time limit for the redhibitory action (called the "short time limit" in Article 1648) runs from the discovery of the defect by the buyer. However, in this case, Roy only became aware of the true extent of the defects through the expert report of 8 January 1969. The first symptoms (noises, abnormal behaviour) were not enough to constitute a certain and complete discovery. Thus, the filing of the report constituted the starting point of the time limit, and the summons of 23 January 1969, only 15 days later, was perfectly within time.

What should be remembered? The seller argued that the "short time limit" should run from the appearance of the first signs. The Court rejected this interpretation: as long as the buyer does not have precise and objective knowledge of the defect (for example through an expert report), the time limit does not start. This is legal certainty for buyers, who are not required to act at the slightest doubt but can take the time to have the item examined.

What this means for you — concretely

This 1971 case law remains the rule today. Concretely, if you are in one of these situations:

• Landlord (Lessor): You let a flat in Belfort; if the tenant discovers a latent defect (e.g., invisible mould at the visit), they can act against you from the moment they become aware of it, even if the lease was signed several months ago. The time limit is, however, "short", meaning they must act quickly after the discovery (a few weeks to a few months depending on the judges).
• Buyer of a property (car, house, etc.): You buy a used car in Danjoutin. Two months later, the engine breaks down. An expert report reveals abnormal wear prior to the sale. You have until the date of the expert report to act. But be careful, the "short time limit" requires you to file a claim quickly after that date: 15 days as in the Roy case is ideal, but one or two months may be accepted if you can justify prior amicable steps.
• Professional or private seller: Beware! If you sell a property with a defect that you knew or should have known about, you will be liable for it. The fact that the buyer discovers the defect late does not protect you: the time limit runs in their favour.

Example with figures: In Belfort, a buyer paid £12,000 for a used car. An expert report carried out six months after purchase reveals a serious latent defect. They obtain in court a price reduction of £4,000, corresponding to the cost of repairs. Without this case law, their action would have been declared inadmissible because they had not acted "within a short time limit" from the sale.

Four tips to avoid this type of dispute

• Have the property inspected before purchase: For any major purchase (car, house, expensive equipment), use an independent expert before signing. In Belfort or Danjoutin, a thorough technical inspection of a used car costs about £150, which can save you a loss of several thousand pounds.
• Record all information in writing: At the time of sale, ask the seller to fill out a written questionnaire about the condition of the property. In the event of a dispute, these statements will be valuable to prove that the seller knew (or should have known) the defect.
• Act without delay after discovery: As soon as you have a serious doubt (suspicious noise, crack, etc.), have the defect noted by a professional and, if the expert report confirms a latent defect, file a claim quickly. Do not wait: the "short time limit" is generally a few weeks to two months at most after actual discovery.
• Keep all supporting documents: Keep invoices, expert reports, correspondence with the seller, and any document proving the date you became aware of the defect. These elements are essential to show that your action is within time.

Further reading: related case law and developments

The 1971 judgment is still the reference, but it has been confirmed and clarified later. For example, the Court of Cassation ruled in a judgment of 18 May 1983 (No. 81-16.207) that the "short time limit" is assessed at the discretion of the lower courts, depending on the circumstances of each case. Thus, a two-month period may be considered short if the buyer attempted an amicable resolution, while a three-week period may be considered too long if no steps were taken.

More recently, the Law of 17 March 2014 (known as the Hamon Law) introduced a limitation period of two years for the action on latent defects in real estate sales. But for movable property (cars, household appliances, etc.), the "short time limit" derived from Article 1648 of the Civil Code continues to apply, with the starting point fixed at the discovery of the defect.

The trend is therefore consistent: the courts protect the buyer by allowing a reasonable time from the actual knowledge of the defect. However, be careful: this time limit may be very short if the buyer was a professional (e.g., a mechanic), as they are presumed to discover defects more quickly.

Frequently asked questions

1. Q: I have just discovered a latent defect on my car bought six months ago in Belfort. Do I still have time to act? A: Yes, if you only became aware of the defect recently (e.g., after an expert report). The time limit runs from that discovery, but you must act within the following weeks, ideally less than a month.
2. Q: What should I do if the seller refuses to acknowledge the defect? A: Immediately have a judicial expert report (or a bailiff's report) made to establish the existence and pre-existence of the defect. Then file a claim before the competent judicial court (that of Belfort if the seller lives there).
3. Q: Can I act if I have already resold the property? A: Yes, the redhibitory action is available to the initial buyer, even if they have resold the property in the meantime. You can request a price reduction or avoidance of the sale.
4. Q: Is the time limit the same for real estate? A: Since 2014, the action for latent defects in real estate is subject to a two-year limitation period from the discovery of the defect, but the starting point remains the same: the day you become aware of it (often the expert report).
5. Q: How much does a legal action for latent defect cost? A: Lawyer and expert fees vary. An initial consultation with a specialist lawyer (such as Maître Zakine) costs about £45 for 30 minutes. For a full action, expect between £1,500 and £5,000 depending on complexity, but success can bring you much more.
