Summary : Did you buy a defective product more than a few weeks ago? Good news: French law protects you for two years from delivery. Even after one year, you can demand the replacement, repair, or refund of your purchase. Learn how to enforce your rights against uncooperative sellers, without costs or complications.
In short : The statutory guarantee of conformity gives you two years of protection for any purchase from a professional. After the first year, it is up to you to prove the existence of the defect, but you still retain strong rights. A presumption of pre-existence facilitates your claim during the first twenty-four months. The free replacement of a defective product remains possible, complemented by amicable remedies (mediation) and judicial remedies if necessary. Sellers cannot circumvent these rights with false arguments: you have concrete solutions to activate.
âïž Why the statutory guarantee of conformity protects consumers beyond one year
Buying a phone, a washing machine or a piece of furniture of quality implies being able to enjoy it worry-free for a reasonable time. The statutory guarantee of conformity meets this expectation by imposing on the professional seller a fundamental obligation: to deliver a good that conforms to the contract and is free from defects. This protection, provided for in articles L.217-1 to L.217-20 of the Consumer Code, operates independently of commercial warranties and cannot be excluded by any contractual clause.
Contrary to what many consumers believe, the guarantee does not magically stop after one year. It extends over two full years from the date the good is delivered. After twelve months, the rules change, but your rights remain. This is a crucial point that few sellers voluntarily explain.
đĄïž The legal framework of the guarantee after twelve months
During the first year following purchase, the law provides a mechanism extremely favorable to the consumer: the presumption of pre-existence of the defect. Simply put, if your product shows a defect within these twelve months, it is automatically presumed to have existed at the time of sale. It is up to the seller to prove otherwise, which they can do only by demonstrating misuse on your part, an accident, or normal wear and tear.

After this first year and up to the two-year term, the situation legally reverses. It is up to you to prove that the defect existed at the time of purchase, even if it only manifested later. This reversal of the burden of proof makes things more complex, but far from insurmountable. Circumstantial evidence, witness statements or a technical expert report often suffice to establish the prior existence of the defect.
Letâs take a concrete example: your refrigerator works correctly for thirteen months, then the compressor stops working. You invoke the statutory guarantee. The seller will argue that thirteen months of use caused the failure. Itâs up to you to show, for example, that this type of compressor has a much longer certified lifespan, or that the defect stems from a preexisting manufacturing fault. A technical diagnosis can be enough to tip the balance in your favor.
đ The three consumer protection mechanisms to know
French law offers the consumer three distinct tools to protect themselves against defective products. Each operates under specific rules, and combining them can strengthen your position against the seller or manufacturer.
đ The statutory guarantee of conformity: your main weapon
This is the most powerful shield at your disposal. The statutory guarantee of conformity applies automatically, without formalities or prior steps. It covers a good that does not match its description, does not have the advertised qualities or does not meet the use normally expected.
A product is considered nonâconforming when it does not match the promised characteristics, does not offer the performances announced on the label or in advertising, or cannot be used for its primary purpose. No manufacturing defect can be excluded: the seller is liable for everything, even if they are not directly responsible.
The twoâyear period is your real asset. For second-hand goods, this period can be reduced to one year if buyer and seller agree, but never below that. This legal framework effectively protects consumers from bad-faith arguments.
âïž The warranty against hidden defects: when itâs more serious
This mechanism, older in origin, is set out in the Civil Code (articles 1641 to 1649). It protects the consumer against serious defects concealed at the time of purchase. Unlike the guarantee of conformity, it applies even between private individuals, which makes it useful when buying second-hand on resale platforms.
Three cumulative conditions must be met: the defect must be hidden (not visible at the time of purchase), anterior to the sale (it must have existed at the time of your acquisition), and serious (it renders the good unfit for use or greatly diminishes its usefulness). You have two years from the discovery of the defect to take action, within a limit of five years after purchase.
The major challenge: it is up to you to prove all these elements. A technical expert report often becomes necessary, hence a potential cost at your expense. That is why the guarantee of conformity generally remains easier to mobilize.
đ The commercial warranty: a voluntary commitment by the professional
Unlike the previous two, this one exists only if the seller or manufacturer offers it. It complements the legal guarantees and can never reduce or cancel them. Its conditions are freely defined by the professional: duration, coverage, exclusions.
Beware of commercial traps : some sellers present their commercial warranty as the only protection available, which is false. Even if it expires, the legal guarantees continue to apply during their respective time limits. Never let yourself be intimidated by a seller claiming that “the warranty is over” if you are still within the twoâyear legal window.
The commercial warranty must be formalized in writing and must mention the existence of the legal guarantees. This is a legal requirement that strengthens your protection.
đŻ The presumption of pre-existence: the reversal of the burden of proof in your favor
This legislative mechanism is revolutionary for the consumer. Its operation is simple: any defect appearing within the first twenty-four months is presumed to have existed at the time of sale. The seller can only contest this presumption if they prove one of the following causes: misuse of the product, an accident or shock after purchase, normal wear and tear, or lack of maintenance attributable to the consumer.
Practically speaking, you no longer need to agonize over establishing the origin of the defect. You simply report the problem to the seller, who assumes the burden of justifying their refusal. This reversal changes everything in practice. Without it, you would have to finance a technical expert report to prove that the defect preexisted â a ruinous investment for an ordinary consumer product.
An eloquent example: your dishwasher washes poorly after six months. You contact the seller invoking the statutory guarantee of conformity. The seller claims it is a user problem? It is up to them to demonstrate it, not to you to disprove it. If they cannot provide tangible proof (for example, clear improper use), they are legally required to repair or replace the appliance.
â Your three options when facing a defective product after twelve months
Once you have established the existence of a conformity defect, the law offers you several paths to obtain redress. The seller cannot impose one option over another, unless your choice would result in a cost manifestly disproportionate compared to the other option, considering the value of the good.
đ§ Free repair or replacement
This is the first solution to request. You can choose between repairing and replacing the defective good, and this operation must be carried out at no cost to you: parts, labor, transport, everything is the sellerâs responsibility. The intervention deadline must be reasonable, generally set at a maximum of one month.
During this repair or replacement period, you are not liable for a usage indemnity for having used the good before the defect occurred. In other words, if your phone worked correctly for four months before breaking down, the seller cannot claim the cost of your use during that period.
For products whose model no longer exists (discontinued, out of stock), replacement takes on particular importance. The seller cannot hide behind unavailability to refuse any solution. In that case, a refund is required.
đ° Refund or price reduction
If repair and replacement are impossible, or if the seller refuses to act within a reasonable time, you can demand a full refund of the good. In return, you must return the defective product. This refund is made to the same payment method used at purchase: if you paid by bank card, the refund will be credited to that card.
Beware of a common trap : some sellers try to impose a store credit or voucher instead of a cash refund. That is illegal. You have the right to demand a refund in euros if the legal conditions are met.
You can also request a price reduction if you wish to keep the good despite the defect. This reduction must be proportionate to the seriousness of the defect and to the decrease in the productâs value. For example, if you bought a sofa for âŹ2,000 and the upholstery has a minor cosmetic defect, a reduction of âŹ150 to âŹ200 may be appropriate.
đ Concrete steps to assert your rights
Enforcing the statutory guarantee of conformity requires method, but no special legal expertise. Here is the typical path to reach a satisfactory solution.
đ Step 1: gather your evidence
Before any action, build a solid file. You will need your invoice or proof of purchase: receipt, online order confirmation, bank statement. Photos or videos of the defect strengthen your position. Also keep prior correspondence with the seller: emails, messages, live chats.
Witness statements from third parties who observed the problem can prove useful in the event of a later dispute. Also keep the original packaging and accessories of the product: they may be requested during a refund or an expert assessment. If you have a technical expert report, include it in your file, although it is not mandatory under the statutory guarantee of conformity.
âïž Step 2: contact the seller in writing
Never rely solely on a phone call or an in-person conversation to claim your rights. Send a written complaint to the seller: registered letter with acknowledgment of receipt or email with read receipt. This letter must mention precisely the date and place of purchase, the product reference, a detailed description of the defect observed.
Explicitly cite the statutory guarantee of conformity by invoking articles L.217-1 and following of the Consumer Code. Formalize your request: repair, replacement or refund. Set a reasonable response deadline, generally fifteen days. This formality creates an official record of your démarche, essential if you need to escalate the conflict.
⥠Step 3: the formal notice
If the seller does not respond or refuses your request without serious justification, send a formal notice by registered letter with acknowledgment of receipt. This formal letter recalls the history, cites the applicable legal texts, and sets an imperative deadline of eight to fifteen days to perform the obligation. Clearly state that you will pursue further remedies in case of refusal.
The formal notice is not a mere administrative formality: it constitutes a required prerequisite to any legal action and demonstrates your good faith. A judge will systematically check whether this step was taken before ruling.
đ€ Step 4: use free mediation
Since the consumer law, every professional selling to consumers must obligatorily offer a free mediation mechanism. The mediator is an independent third party who examines the dispute impartially and proposes an amicable solution to both parties.
To contact the mediator, identify them on the sellerâs website or in their terms and conditions of sale. Send your complete file: initial complaint, formal notice, evidence. The mediator has three weeks to accept or refuse your file. If they accept it, they issue their proposal within a maximum of 90 days.
The major advantage: this procedure is entirely free, fast, and much less stressful than going to court. Although the mediatorâs proposal is not legally binding, most professionals accept it to avoid costly litigation. In practice, mediation succeeds in the majority of cases.
It also suspends the limitation period, giving you more time to explore other solutions if mediation fails.
âïž Step 5: bring the case to court if necessary
If mediation fails or the professional refuses any solution, you can initiate legal action. The court to be seized depends on the amount in dispute: for disputes under âŹ5,000, the local court is competent, and you do not necessarily need a lawyer.
For amounts between âŹ5,000 and âŹ10,000, bring the case before the judicial court (a lawyer is not mandatory but recommended). Above âŹ10,000, representation by a lawyer becomes mandatory. For small disputes, you can use the injunction to perform procedure, which allows the judge to order the professional directly to fulfill their obligation without an initial adversarial hearing.
Access to justice is now realistic for the average consumer: costs are reduced, the procedure is simplified, and you do not need a law professor to defend your position.
â ïž Fatal mistakes to absolutely avoid
Certain actions can penalize you significantly. Knowing these traps protects you.
đ« Accepting store credit instead of a refund
When you are legally entitled to a refund, the seller cannot forbid it by offering you a voucher or store credit. That is illegal. You have the right to demand a refund in euros to the bank account or payment method used originally.
Some sellers play on ambiguity by presenting store credit as a generous solution, sometimes even with an overvalue (“we offer you âŹ2,100 of store credit for your âŹ2,000 purchase”). Do not be seduced: a cash refund remains your fundamental right. A formal written refusal of the voucher and demand for a refund will generally be enough to force the seller to comply.
đ Being intimidated by false arguments
Some professionals use fraudulent pretexts to refuse the guarantee. Here are the most common and how to respond: “The manufacturer's warranty is over” â this does not eliminate the statutory guarantee of conformity, which operates independently.
“You should have reported the defect earlier” â you have two full years to act without having to justify the timing. “The defect is due to your use” â it is up to the seller to prove this formally under the guarantee of conformity, not you to establish it. “We do not refund, only give store credit” â this is directly contrary to the law.
đŻ Throwing away the packaging or the defective product
Always keep the defective product, its packaging and all accessories, even if it seems unusable. They may be requested during a technical expert assessment or in case of a refund. A discarded product makes any subsequent verification impossible and significantly weakens your legal position.
đš Trying to repair the product yourself
If you intervene yourself to repair or disassemble the product, the seller may argue that the defect results from your manipulation. Wait for the professional's decision before touching it. Only an authorized and documented repair by the seller or an authorized third party counts legally.
đ Common situations and their resolution
Certain purchase scenarios recur regularly. Hereâs how to deal with them effectively.
đ± Faulty high-tech product
Your smartphone shows a flickering screen after three months, or your laptop overheats chronically. You are clearly within the two-year period: the presumption of pre-existence works in your favor. Contact the seller (not the manufacturer) to request repair or replacement.
Put your complaint in writing citing articles L.217-1 and following. The seller must act at no cost. If they refuse, send a formal notice and contact the mediator. High-tech products are particularly sensitive to conformity defects: most professionals prefer to comply quickly rather than face escalation.
đœïž Household appliance that does not perform its function
A dishwasher that leaves marks on the dishes despite apparently normal operation, a hob that heats unevenly, or a refrigerator that does not maintain the required temperature: these are clear conformity defects. The good does not fulfill its expected function.
The seller cannot tell you “the appliance works technically”. That is inaccurate: an appliance that does not work according to its primary purpose is defective. Demand replacement. Faulty household appliances rarely lead to prolonged disputes because the proof of the defect is generally visible and indisputable.
đïž Furniture that deteriorates prematurely
A sofa whose upholstery peels after three months, a table whose varnish flakes for no reason, or a chair whose legs become repeatedly loose: these are conformity defects. Normal wear cannot be invoked for a product so recent.
Take photos of the defect and document the context: date of purchase, normal storage conditions, absence of mistreatment. Demand replacement or, if the model is no longer produced, a full refund. Furniture can be more difficult to replace than electronic products, hence the importance of written records of your request.
đ Online purchases: additional protections
Distance purchases benefit from strengthened legal protection. You enjoy the fourteen-day right of withdrawal without having to justify a reason, which is in addition to the guarantee of conformity. This right operates independently and offers an alternative route.
If your product ordered online turns out to be defective and you are still within the withdrawal window, favor the right of withdrawal: it is simpler and does not require any justification. After this fourteenâday period, switch to the statutory guarantee of conformity, which covers the following two years.
Keep all records of communication with the online seller. Ethical marketplaces often offer effective after-sales services: use the complaint menus integrated into those sites, which leave public traces and encourage sellers to cooperate quickly.
đ Template for a formal notice
Here are the essential elements to include in your formal notice so that it is legally sound:
Header : your full contact details (name, address, phone, email) and those of the seller (name, address, customer number if applicable).
Subject : Formal notice â Statutory guarantee of conformity.
Body of the letter : Precise reminder of the purchase (date, place, product reference, amount paid). Factual description of the defect observed and date of appearance. Mention of the initial complaint left unanswered or refused. Explicit reference to articles L.217-1 to L.217-20 of the Consumer Code. Invocation of the presumption of pre-existence of the defect (crucial for defects appearing within two years). Clear and precise request: repair, replacement or refund. Imperative deadline of fifteen days to act. Mention of the remedies envisaged if refused: mediation, then court.
Mandatory sending : registered letter with acknowledgment of receipt. Keep a copy of everything you send.
đŻ Summary of consumer rights regarding defective products
You have two full years of protection from the delivery of the good. During the first year, the presumption of pre-existence favors you greatly: any defect is presumed to be preexisting, and it is up to the seller to prove otherwise. After one year and until the end of two years, it is up to you to prove the prior existence of the defect, but this remains achievable through circumstantial evidence or an expert report.
You can demand free repair or replacement of the product with no additional costs. If these solutions are impossible or refused, a full refund is required. A price reduction is also an option if you keep the good despite the defect.
Amicable remedies (written complaint, formal notice, free mediation) succeed in the majority of cases. Access to justice is made easier for small disputes: no lawyer required up to âŹ10,000. Sellers cannot circumvent these rights by contractual clauses or false arguments: the law always prevails.
Faced with a defective product, never remain passive. Document the problem, contact the seller in writing, and escalate your remedies progressively. The right to replacement of a defective product is a fundamental right expressly guaranteed by law. The only real limit remains your determination to exercise it. Sellers count on consumer inertia: donât give them that satisfaction.
