Limiting or Excluding Warranties in B2B Sales in France

Freedom to limit or exclude warranties between professionals

The default warranties a French seller owes — conforming delivery, the warranty against hidden defects and the warranty against eviction — are, for the most part, supplétifs de volonté: default rules that the parties may vary. That is why a limit warranty clause is a routine feature of French sale contracts and general terms and conditions. In a business-to-business sale, the starting position is contractual freedom: the seller may narrow the warranty to certain defects, cap its financial exposure, shorten a claim window or exclude a warranty altogether.

That freedom is real but it is fenced. French law overlays three distinct controls on any attempt to limit or exclude warranties in B2B sales. The first is warranty-specific: the rules on excluding the hidden-defects guarantee turn on the status of the parties and on the seller's presumed knowledge. The second is the doctrine that a clause cannot hollow out the very obligation the contract exists to perform. The third is the modern control of significant imbalance, which reaches abusive terms even between two businesses.

For a foreign seller supplying into France, or a foreign buyer purchasing from a French supplier, the practical lesson is that the wording of your clause matters far less than where the parties sit within these controls. A clause copied from an English-law template will often be read down or set aside by a French court. The sections below map each control, so you can tell in advance whether your limit warranty clause will survive a challenge.

Excluding the warranty against hidden defects

The warranty against hidden defects makes the seller answer for a latent flaw that renders the goods unfit for their intended use. Because the governing articles are default rules, a seller may in principle exclude or limit that warranty. Whether the exclusion works, however, depends on who the seller is and who the buyer is — the analysis is not the same for a private seller as for a professional.

Where the seller is not a professional, an exclusion clause is valid, but it is deprived of effect if the seller acted in bad faith — that is, if the seller in fact knew of the defect and concealed it. This is the principle drawn from Article 1643 of the Civil Code: the seller escapes the hidden-defects warranty by a clause only for defects it did not know about. A non-professional who has particular competence over the goods, or who built or installed the defective part, is treated by the courts as a professional for this purpose.

Where the seller is a professional, French case law presumes — irrebuttably — that the seller knew of the defect. The consequence is decisive: a professional seller is treated as being in bad faith, so it cannot shelter behind its own exclusion clause against a buyer it is not permitted to exclude. The buyer's status then splits the outcome. Against a consumer or non-professional buyer, the exclusion is unfair and struck out under the Consumer Code. Against a professional buyer, the exclusion holds only if the buyer is a professional of the same speciality as the seller; if the buyer operates in a different field, the presumption of bad faith applies in full and the clause fails.

Two further limits close off common workarounds. A professional seller cannot use a limitation or exclusion clause to escape damages for its own fault, so it cannot contract out of Article 1645 of the Civil Code, under which a seller who knew of the defect owes the buyer full damages on top of restitution of the price. And the same-speciality test is applied strictly: it asks whether the buyer had the technical competence to detect the flaw, not merely whether both parties are businesses.

Limiting the conformity and delivery obligations

Conforming delivery — handing over goods that match the contract in identity, quantity and quality — is a distinct regime from the hidden-defects warranty, and it is the seller's essential obligation. Because it sits at the heart of the sale, the room to limit it is narrower. A clause that purports to relieve the seller of liability for failing to deliver conforming goods risks being treated as an élusive clause that strikes at the essence of the contract, and is then deemed unwritten.

The controlling idea comes from Article 1170 of the Civil Code: any clause that deprives a debtor's essential obligation of its substance is deemed unwritten. A wholesale exclusion of the duty to deliver what was agreed cannot stand, because it would leave the buyer paying a price for a promise the seller is free to break. By contrast, a clause that merely limits the seller's liability — for instance a monetary cap, or a narrowing of recoverable heads of loss — is permissible between businesses, provided it does not go so far as to neutralise the obligation.

The distinction between conformity and hidden defects matters here because it fixes which limitation rules apply and which time limits run. A mismatch between the goods delivered and the goods sold is a conformity problem, governed by the general law of non-performance and its five-year prescription. A latent flaw affecting the use of goods that do match the contract is a hidden defect, with its own two-year window. A limitation clause drafted for one regime does not automatically cover the other, and a court will characterise the claim by its substance, not by the label the parties or the clause attach to it.

Liability caps and the essential-obligation limit

A liability cap — a clause fixing a ceiling on the damages the seller can be ordered to pay — is the most common commercial tool for allocating risk in a B2B supply. French law accepts caps in principle between professionals. But a cap is not immune from control simply because both parties are sophisticated businesses that negotiated it, and a limit warranty clause that includes a cap must clear two well-established hurdles.

The first is the essential-obligation limit, developed in the line of Cour de cassation authority often called the Chronopost doctrine. Where a clause caps liability at a figure so low that it contradicts the scope of the seller's essential obligation — in effect promising performance while removing any real sanction for non-performance — the cap is deemed unwritten. The reasoning tracks Article 1170 of the Civil Code: a cap that empties the core promise of its substance cannot survive. A cap set at a token fraction of the contract value, applied to the seller's central duty, is the classic casualty.

The second hurdle is fault. A liability cap does not shield a seller against the consequences of its own gross negligence (faute lourde) or intentional fault (faute dolosive). A cap drafted to apply come what may will be disapplied where the seller's breach reaches that threshold. Combined with the presumption that a professional seller knows the defects in its goods, this means a cap offers far less protection on the warranty side than a foreign seller might expect from an equivalent English or German clause.

Control of significant imbalance between businesses

For many years abusive-term control was reserved to consumers. That is no longer the case. Two provisions now let a business challenge a warranty limitation imposed on it, even in a purely B2B relationship, on the ground that the clause creates a significant imbalance in the parties' rights and obligations. This is the control most often overlooked by foreign suppliers relying on their standard terms.

Article L442-1 of the Commercial Code allows a business to seek damages, and the removal of the clause, where a party with commercial power subjects or attempts to subject the other to obligations creating a significant imbalance. It is enforced not only by the aggrieved business but also by the public authorities, and it applies squarely to one-sided warranty and liability terms in general conditions of sale. Alongside it, Article 1171 of the Civil Code deems unwritten any clause in a contract of adhesion — a contract whose non-negotiable terms are set in advance by one party — that creates a significant imbalance between the parties.

Neither control weighs the price or the adequacy of the main subject matter; both target the allocation of rights around it. A warranty clause that strips the buyer of every remedy while leaving the seller's own position untouched is the paradigm of significant imbalance. The practical takeaway is that a limitation clause negotiated on genuinely mutual terms, or balanced by a corresponding concession, is far more defensible than a take-it-or-leave-it exclusion buried in standard terms.

Where limitation is simply forbidden

Some warranty limitations are not merely vulnerable but flatly barred, and it helps a B2B seller to know the outer boundary. The first bar is consumer law. In a sale between a professional seller and a consumer or non-professional buyer, a clause that removes or reduces the buyer's right to a remedy for the seller's breach is unfair and deemed unwritten. There is no room to exclude the hidden-defects warranty against a consumer, and a business that sometimes sells to consumers should keep separate terms for those sales.

The second bar concerns the warranty against eviction. The seller's warranty against disturbance arising from its own act — the garantie du fait personnel — is a matter of public policy and cannot be excluded by any clause, in a B2B sale or otherwise. A seller cannot promise the buyer peaceful possession and then reserve, by clause, the right to disturb it. By contrast, the warranty against eviction by third parties can be limited by agreement, subject to the rule that the seller must in any event return the price unless the buyer knowingly bought at its own risk.

Reading these bars together with the earlier controls gives a clear hierarchy. Eviction by the seller's own act cannot be touched. Consumer remedies cannot be cut down. The hidden-defects warranty can be excluded only within the same-speciality rule. Everything else — conformity, delivery, third-party eviction and quantified caps — can be shaped between businesses, but only up to the essential-obligation and significant-imbalance limits.

Drafting an effective, enforceable limitation clause

Because the controls are cumulative, an enforceable limit warranty clause is built by working through each of them rather than by finding a magic form of words. The aim is a clause that limits exposure without crossing into an exclusion the law refuses to recognise. A well-constructed clause identifies precisely which warranty it addresses, respects the seller's essential obligation, and leaves the buyer a real remedy.

It also pays to align the clause with the commercial reality of the deal. A cap proportionate to the contract value, a claim window that gives the buyer a fair opportunity to notify defects, and an express reservation for gross and intentional fault all make the clause look balanced rather than one-sided — which is exactly what the significant-imbalance control examines. The steps below set out a practical sequence for the review.

Putting a valid B2B warranty clause together

The recurring mistake foreign businesses make is to treat a warranty exclusion as a matter of drafting confidence — the firmer the wording, the stronger the protection. Under French law the opposite is often true: the broader and more absolute the exclusion, the more likely it is to hit the essential-obligation limit or the significant-imbalance control and be treated as unwritten. A modest, precise limit warranty clause outperforms an aggressive one.

For sellers, the priority is to know your own status. A professional seller carries the irrebuttable presumption of knowledge, so it should plan around a cap and a fair claims process rather than around a hidden-defects exclusion it cannot use against a buyer in another trade. For buyers, the value lies in recognising when a supplier's standard terms overreach — a differently specialised buyer, a consumer-facing purchase, or a token cap all point to a clause that a French court may disregard.

Both sides benefit from settling the point before the goods move, not after a dispute. Once a defect surfaces, the argument over whether a clause is enforceable becomes entangled with the deadline to sue and the burden of proving what the seller knew. Getting the warranty allocation right in the contract, in line with the controls set out above, is the cheapest insurance either party can buy.

Frequently asked questions about limiting warranties in B2B sales

Can I exclude the hidden-defects warranty in France?

Between two businesses you can, but only if you are professionals of the same speciality. Because a professional seller is irrebuttably presumed to know of the defect, an exclusion is deprived of effect against a professional buyer in a different field, and it is void against a consumer.

Are liability caps enforceable in a B2B sale?

Yes, in principle, between professionals. A cap is disapplied, however, if it contradicts the seller's essential obligation under the Chronopost doctrine and Article 1170 of the Civil Code, or if the breach amounts to gross or intentional fault. Set the cap at a serious figure and carve out those faults.

Can a warranty exclusion be struck down between businesses?

It can. Even in a purely B2B relationship, Article L442-1 of the Commercial Code and Article 1171 of the Civil Code allow a business to challenge a clause creating a significant imbalance. A one-sided exclusion that strips the buyer of every remedy is the classic target.

Does a warranty exclusion work against a consumer?

No. A clause that removes or reduces a consumer's right to a remedy for the seller's breach is unfair and deemed unwritten. A business that sometimes sells to consumers should keep a separate set of terms for those sales.

What is significant imbalance?

It is a marked one-sidedness in the parties' rights and obligations, controlled by Article L442-1 of the Commercial Code and, for adhesion contracts, Article 1171 of the Civil Code. The controls do not judge the price; they target the allocation of rights around it, such as a clause leaving the buyer with no remedy.

What does the same-speciality rule actually test?

It asks whether the buyer had the technical competence to detect the defect, not merely whether both parties are businesses. A buyer in the seller's own trade is treated as able to inspect; a buyer in a different field keeps the protection of the presumption that the professional seller knew of the flaw.

Can a seller cap damages for its own fault?

Not for gross negligence or intentional fault, and not to escape Article 1645 of the Civil Code, under which a seller who knew of the defect owes full damages. A professional seller, being presumed to know its goods' defects, cannot use a cap to avoid those damages.
