The penalty clause in France: how a clause pénale works and when a judge can cut it

What a penalty clause is under French law (Article 1231-5)

A penalty clause in France, known as a clause pénale, is a provision by which the parties agree in advance the sum one of them will owe the other if it fails to perform, or performs late. Article 1231-5 of the Civil Code defines it as a stipulation that a party who does not carry out the contract will pay a fixed sum by way of damages. In the sale of goods it is a common tool: a supplier and a buyer set a figure now, so that neither has to prove and quantify its loss later. The clause is the French cousin of what common-law systems call liquidated damages, though the two are not identical in the way courts police them.

The purpose of a penalty clause in France is twofold. First, it fixes compensation, which spares the creditor the difficult task of proving the exact extent of its harm before a court. Second, it presses the other party to perform, because the agreed sum is usually set above the likely actual loss to make default unattractive. Both functions are recognised by French law, and a well-drafted clause pénale can be one of the most useful terms in a commercial sale, alongside a retention-of-title clause and a clear termination mechanism.

It is important to understand what the clause does and does not do. It replaces the ordinary rules on proving damages: once the breach it targets occurs, the creditor claims the agreed figure without having to establish the amount of its loss. It does not, however, give either party a right to escape the contract by paying the sum. A penalty clause is a sanction for non-performance, not a price for withdrawal. That single distinction separates it from earnest money and from an option to terminate, and it drives much of the case law.

A penalty clause is enforceable — but the judge may reduce or increase it

The starting position is that a penalty clause in France binds the parties like any other term: the court must apply the agreed sum. But Article 1231-5 gives the judge a corrective power. Where the stipulated penalty is manifestly excessive or, conversely, manifestly derisory, the court may reduce or increase it, and it may do so even on its own initiative. This is the single most important feature of the clause pénale, and the reason a headline figure on paper is never the whole story in France.

The threshold is deliberately high. The penalty must be manifestly disproportionate, not merely generous or approximate. French courts do not recalculate the creditor's actual loss and substitute it; they intervene only where the gap between the agreed sum and any plausible harm is obvious. The point of reference is the loss the creditor could suffer, assessed at the time the judge rules, not a rigid comparison with proven damage. A penalty set well above the foreseeable consequences of the breach invites revision; a penalty in a sensible range will be enforced as written.

Crucially, this judicial power is a matter of public policy: the parties cannot waive it. A clause stating that the penalty shall apply in full and without possible reduction, or that the parties renounce any request for revision, is ineffective on that point. The court retains its discretion whatever the contract says. Foreign businesses used to liquidated-damages clauses that are either wholly enforceable or wholly void as penalties should note this middle path: in France the clause survives, but the number may be adjusted by the judge.

Reduction where the contract has been partly performed

Article 1231-5 contains a second corrective, distinct from the excess/derisory control. Where the debtor has performed the contract in part, the penalty may be reduced by the judge in proportion to the benefit that partial performance has procured for the creditor. This rule protects a party who has done most of what it promised from being hit with the full penalty as if it had done nothing at all. Like the general revision power, it is public policy and cannot be excluded by the contract.

In a sale of goods this matters where performance is divisible. If a supplier delivers eighty per cent of an order on time and is late only on the balance, a flat penalty calculated on the whole contract value may be cut to reflect the value the buyer actually received. The reduction is not automatic and not arithmetical; the judge weighs the advantage the creditor obtained from what was performed. But the principle is clear: a penalty that ignores substantial partial performance is exposed to reduction on that ground alone, independently of whether it is otherwise excessive.

Drafters can manage this risk by aligning the penalty with the structure of performance. A clause that applies per unit, per day of delay, or per delivery instalment tracks partial performance far better than a single lump sum tied to the entire contract. Where the obligation is genuinely indivisible — a bespoke machine that is useless unless complete — a lump sum is easier to defend, but the clause should say why the obligation is treated as a whole.

The penalty is not owed until you serve a mise en demeure

A penalty clause in France does not trigger itself the moment the deadline passes. As a rule, the penalty becomes payable only once the creditor has put the debtor on notice to perform — the mise en demeure. This is a formal demand, in writing, requiring performance within a stated period, and it is the pivot on which the whole mechanism turns. Skip it, and a debtor can resist the penalty even where the breach is plain.

There is an important exception. The parties may agree that the debtor is placed in default by the mere arrival of the term — a clause stating that any delay runs automatically de plein droit and without any formality. Such wording is valid and dispenses with the notice, but it must be clear and express; French courts do not presume it. In practice, many commercial contracts combine the two: an automatic-default clause for time-critical obligations, and a notice requirement elsewhere. If the contract is silent, the notice is required.

For a foreign creditor this is a frequent and costly trap. A supplier that simply invoices the penalty, or a buyer that cancels an order without a proper prior demand, may find the penalty unenforceable and may even incur liability of its own for wrongful termination. Related timing questions arise for late or non-delivery remedies and when you are terminating a sales contract for breach, where the same notice discipline applies. Get the mise en demeure right before you rely on any penalty.

Penalty clause vs earnest money (arrhes) and liability caps

A penalty clause is easily confused with two neighbouring devices, and the difference decides the outcome. The first is earnest money, or arrhes, under Article 1590 of the Civil Code. Where a sum is given as arrhes, either party may resile from the promise of sale: the buyer by forfeiting the sum paid, the seller by returning double. Arrhes therefore price a right to withdraw. A penalty clause does the opposite — it does not let anyone walk away; it sanctions a party who fails to perform an existing obligation.

The label the parties use is not decisive. French courts look at the intended function: is the sum the cost of an option to withdraw (arrhes), or the pre-agreed damages for breach (penalty)? A deposit described as a penalty may be treated as arrhes, and vice versa, according to the parties' real intention. Because the consequences are opposite — freedom to withdraw versus liability for default — this qualification should be settled expressly in the contract, not left to interpretation.

The second neighbour is the liability-limitation clause (a cap). A penalty fixes what the debtor must pay when it breaches; a cap fixes the maximum the debtor can be made to pay, leaving the creditor to prove its loss up to that ceiling. They can even coexist. The controls differ too: a penalty is policed for manifest excess or derisory amount under Article 1231-5, whereas a cap is tested against other rules, including whether it deprives an essential obligation of substance. Choosing the wrong instrument for your commercial aim is a common drafting error; see our note on key clauses in a French sales contract.

Using a penalty clause for late delivery and late payment

The two most common uses of a penalty clause in France in the sale of goods are late delivery and late payment. For late delivery, a clause typically sets a sum per day or per week of delay, often capped at a percentage of the contract value. This gives the buyer a clean remedy without a fight over the value of lost production or missed onward sales, and gives the supplier certainty about its maximum exposure. The per-day structure also travels well through the partial-performance and excess controls, because it is tied to the actual duration of the default.

On the payment side, care is needed because a distinct regime already applies. In business-to-business sales, statutory late-payment interest and a fixed recovery indemnity are mandatory, and Article 1231-6 of the Civil Code governs damages for the late payment of a sum of money, which as a rule take the form of interest running from the notice to perform. A contractual penalty for late payment can be added, but it operates against this statutory backdrop and must not be used to dress up interest that the law already fixes. Where a creditor has suffered harm beyond the delay through the debtor's bad faith, separate damages may be available.

Both uses are subject to the same guardrails discussed above. A daily delay penalty that compounds into a figure dwarfing any conceivable loss is a classic candidate for reduction as manifestly excessive. A payment penalty that overlaps with statutory interest can be challenged. The safe course is to size the penalty to the realistic consequences of delay, cap it, and coordinate it with the mandatory rules rather than ignore them. Our guidance on late or non-delivery remedies covers how the penalty fits alongside forced delivery, termination and damages.

Drafting a robust and proportionate penalty clause

A penalty clause that survives challenge in France shares a few features. It identifies the precise breach it sanctions, so there is no argument about whether the default falls within it. It sizes the sum to the foreseeable consequences of that breach, avoiding a figure that looks punitive rather than compensatory. And it structures the amount — per day, per unit, per instalment, with a cap — so that partial performance and duration are already reflected. A clause built this way rarely needs the judge's red pen.

Equally important is the machinery around the sum. State whether default runs automatically on the term or requires a mise en demeure, and if a notice is required, describe how it is given. Make clear that the penalty is the agreed measure of damages for the identified breach, distinguishing it from any deposit (which might otherwise be read as arrhes) and from any liability cap in the same contract. Address whether the creditor may, instead of the penalty, pursue performance or termination, so the clause interacts cleanly with the contract's other remedies.

Resist two temptations. The first is the inflated figure locked with a no-revision clause: it does not bind the court and marks the sum as suspect. The second is the vague penalty covering any breach whatsoever, which is harder to enforce because it is untethered from a defined default and a plausible loss. A focused, proportionate, well-signposted clause is worth more in practice than an intimidating one that a judge will trim.

• Define the exact triggering breach — late delivery, non-delivery, late payment — not a catch-all.
• Size the sum to the realistic, foreseeable loss and add a sensible overall cap.
• Structure the amount per day, per unit or per instalment to track duration and partial performance.
• Specify whether default is automatic or needs a written mise en demeure, and how notice is served.
• Distinguish the penalty from any deposit (arrhes) and from any liability cap in the contract.
• Do not insert a clause purporting to exclude the judge's power of revision — it is void on that point.

A practical checklist before you rely on a penalty clause

Before invoking a penalty clause in France, run through a short set of checks. Confirm that the event you are relying on is the exact breach the clause names; that any required notice to perform has been served and its period has expired; and that the sum you intend to claim is defensible against the excess and partial-performance controls. If any of these is shaky, the clause may not deliver what its number promises, and an over-aggressive claim can rebound.

From the debtor's side, the same clause offers routes of defence. If the penalty is manifestly excessive, or performance was substantial, ask the court to reduce it. If no valid mise en demeure was served where one was required, argue the penalty is not yet due. And if the clause is really an escape price rather than a sanction for breach, argue that it is arrhes with the very different consequences that follow. A penalty clause is a two-edged instrument, and the party that understands its limits controls the negotiation.

Frequently asked questions about penalty clauses in France

Are penalty clauses enforceable in France?

Yes. A penalty clause (clause pénale) is enforceable in principle under Article 1231-5 of the Civil Code, and the court must apply the agreed sum. The important qualification is that the judge may reduce a manifestly excessive penalty or increase a derisory one, a power the parties cannot remove by contract.

Can a French judge reduce a penalty?

Yes, and even on its own initiative. Under Article 1231-5 a court may cut a penalty that is manifestly excessive, and may also reduce it where the debtor has performed the contract in part, in proportion to the benefit the creditor received. It may equally raise a penalty that is manifestly derisory.

Can we exclude the judge's power to revise the penalty?

No. The power to moderate a manifestly excessive or derisory penalty is a matter of public policy. A clause stating that the penalty applies in full without possible reduction is void on that point, and the court keeps its discretion whatever the contract says.

What is the difference between a penalty clause and arrhes?

Earnest money (arrhes) under Article 1590 lets a party withdraw from the sale — the buyer by forfeiting the sum, the seller by returning double. A penalty clause does not allow anyone to walk away; it fixes the damages owed by a party that breaches. French courts look at the real intention, not just the label used.

Do I need to send a notice before claiming the penalty?

As a rule, yes. The penalty is due only once you have served a mise en demeure requiring performance and the period has expired. The exception is where the contract expressly provides that the debtor is in default automatically on the term, which dispenses with the notice but must be clearly worded.

Can I use a penalty clause for late payment?

You can, but it operates alongside mandatory rules. In B2B sales, statutory late-payment interest and a fixed recovery indemnity already apply, and Article 1231-6 governs damages for late payment of money, generally in the form of interest. A contractual penalty must be coordinated with these rules and not merely duplicate the interest the law already fixes.

How is a penalty clause different from a liability cap?

A penalty fixes the sum a party must pay when it breaches, without the creditor having to prove its loss. A liability cap fixes the maximum a party can be made to pay, leaving the creditor to prove its actual loss up to that ceiling. They can coexist in the same contract and are policed under different rules.

How our French lawyers help with penalty clauses

Petroff Avocats advises both creditors and debtors on penalty clauses in French sales and supply contracts. For clients drafting or negotiating, we build clauses that are proportionate, correctly triggered and coordinated with the mise en demeure and statutory payment rules, so the figure holds up rather than inviting revision. For clients enforcing or resisting a penalty, we assess whether the breach falls within the clause, whether notice was properly served, and whether the sum is exposed to reduction for manifest excess or partial performance — then we act on that assessment, in negotiation or before the French courts.
