Rupture Brutale: Ending a French Supply Relationship Without Enough Notice

What Article L442-1 says about rupture brutale

French law does not stop you from ending a commercial relationship — but it does penalise ending one abruptly. Under Article L442-1 of the Commercial Code, any person carrying on commercial activities incurs liability if they break off, even partially, an established commercial relationship without written notice that takes account of the duration of the relationship. This is the rule the French call rupture brutale des relations commerciales établies, and it is one of the most litigated provisions in French business law.

The key word is brutale, which here means sudden rather than violent. The wrong the law targets is not the decision to stop dealing with a supplier or customer — that decision is free — but the failure to give the other side enough written warning to reorganise. A rupture brutale can therefore be committed by a party who is entirely within its contractual rights, because the liability is imposed by statute and sits on top of the contract rather than inside it.

Because the claim is statutory and independent of any breach, it is treated as a matter of civil liability rather than pure contract. That distinction matters for foreign parties: it affects which court hears the dispute and which law applies. French specialised commercial courts hear these cases at first instance, and appeals are concentrated before a single court of appeal, which has built up a large and reasonably predictable body of case law on notice periods.

Rupture brutale applies to supply and distribution, not just franchising

Many foreign businesses first meet the rupture brutale rule in a franchise context, but Article L442-1 is far wider. It protects any established commercial relationship, whatever its legal label. That includes recurring supply arrangements, exclusive and non-exclusive distribution, sub-contracting, private-label manufacturing, referencing by a retail chain, and long-running service arrangements. A relationship built purely on a stream of purchase orders, with no framework contract at all, is squarely covered.

This breadth is what surprises non-French counterparties. A supplier abroad that has shipped goods to a French buyer for several years on rolling orders may assume it can simply stop taking new orders. In French eyes, that stream of orders can be an established relationship, and stopping it without notice is a rupture brutale. The same applies in reverse: a French distributor or industrial customer that suddenly drops a foreign supplier can be liable to that supplier.

The liability is independent of any contract breach. You do not need to have broken the contract to be liable, and — importantly — the fact that your contract has expired, or contains a clause allowing termination, does not by itself protect you. The statute overrides a contractual notice period that is too short for the relationship in question. A ninety-day termination clause in a ten-year supply deal will not save you if the courts consider that eighteen months were owed.

What makes a commercial relationship established

Only an established relationship attracts protection, so the first battleground in any rupture brutale case is whether the dealings had that quality. The courts look for a relationship that was stable, regular and significant — one that gave the other party a reasonable expectation that the flow of business would continue. A single order, a one-off project, or purely occasional dealings will not qualify.

The relationship does not need to rest on a written contract or even on a continuous one. A succession of fixed-term contracts, or a long series of repeated orders over several years, can together form one established relationship. The French courts assess the reality of the commercial ties, not their paperwork: regularity of orders, growth in volumes, and the length of the overall dealing all count towards showing that the relationship was settled and expected to last.

Certain features weaken the claim that a relationship is established. Business won through competitive tenders that are periodically re-run, or a relationship the parties always treated as precarious, may not generate a legitimate expectation of continuity. Where a relationship has been formally put on notice as uncertain, or is subject to regular renegotiation from scratch, the protected expectation is harder to prove. These questions are fact-heavy, and the outcome turns on the evidence of how the parties actually behaved over time.

How the required notice period is set

There is no fixed statutory notice period. Article L442-1 requires written notice that takes account of the duration of the relationship and of trade usage. The whole dispute in most cases is how long that notice should have been. The courts weigh a cluster of factors and fix a figure that would have let the victim reorganise — find new customers, new suppliers or a new use for dedicated capacity.

The duration of the relationship is the anchor: as a rough working rule, French courts often reason in terms of roughly one month of notice per year of relationship, though this is only a starting point, not a formula. Other factors push the figure up or down, and a very long or highly dependent relationship can command substantially more than that rule of thumb would suggest.

The main factors the courts weigh are set out below. The heavier these weigh, the longer the notice a party should have given before ending the relationship.

• Length of the relationship — the single most important factor; longer dealings command longer notice.
• Economic dependence — how large a share of the victim's turnover the relationship represented, and whether it was effectively captive.
• Trade usage and any inter-professional agreements in the relevant sector.
• Difficulty of reconversion — how hard it is to replace the lost business or redeploy dedicated assets, staff or stock.
• Specific investments, exclusivity and the nature of the products — dedicated tooling, exclusive supply or a specialised product all lengthen the notice owed.

Crucially, the notice must be real. Giving formal notice on paper while at the same time slashing orders, changing prices unilaterally or degrading the terms of trade will not count: the courts look at whether the party could actually keep operating on normal terms during the notice period. A notice served but not honoured is treated as no notice at all.

The eighteen-month cap introduced in 2019

Before 2019, there was no ceiling on the notice a court could find was owed, and some decisions imposed very long periods, which made exposure hard to predict for a foreign party. The 2019 reform of the Commercial Code changed this by writing a safe harbour into Article L442-1: a party who gives eighteen months of written notice cannot be held liable for having given insufficient notice.

The cap works one way only. It is a shield, not a target. If you actually give eighteen months, you are protected however long or dependent the relationship was — the court cannot rule that even more was owed. But the cap does not mean eighteen months is the required period in every case; for most relationships the notice properly owed is far shorter, and giving eighteen months where six would do simply buys certainty at a commercial cost.

The cap does not change the two situations in which no notice is required at all (covered below), nor does it excuse a notice that is served but not respected. It simply gives the terminating party a definite upper bound. For planning purposes, this makes the eighteen-month figure the natural reference point whenever a relationship is old, large or one where the counterparty is heavily dependent.

Partial rupture: cutting volumes or withdrawing a territory

Article L442-1 catches a relationship that is broken off even in part. A rupture brutale does not require you to stop dealing altogether. A sharp, unilateral reduction in orders, the withdrawal of an exclusive territory, the removal of a product line, or a sudden and material worsening of prices or payment terms can all amount to a partial rupture if the change substantially alters the relationship without notice.

The test is whether the change is significant enough to upset the economy of the relationship. A modest, ordinary fluctuation in volumes — the normal ebb and flow of trade — is not a rupture. But a steep, one-sided cut that leaves the counterparty with unusable capacity or stock, imposed overnight, is treated much like a full termination and requires proportionate written notice. Foreign groups sometimes trigger a partial rupture inadvertently, for example by re-allocating a French customer's volumes to another entity within the group.

Unilateral changes to commercial terms are a common trap. Announcing new prices, new minimum quantities, or a new distribution model and imposing them immediately can be a partial rupture even though the relationship formally continues. The safe course is to propose material changes with the same notice you would give for a termination, so the other party has time to accept them or to reorganise around them.

The exceptions: non-performance and force majeure

Article L442-1 itself preserves two situations in which a relationship may be ended without any notice. The first is the other party's non-performance: where the counterparty has failed to perform its obligations, and that failure is sufficiently serious, you may terminate immediately without exposing yourself to a rupture brutale claim. The second is force majeure: an unforeseeable and irresistible external event that makes continued performance impossible.

Both exceptions are read narrowly. For non-performance, ordinary or minor grievances are not enough — the breach must be grave enough to justify an immediate rupture, and a party who tolerated the same conduct for a long time will find it hard to argue that it suddenly justified cutting all notice. You must be able to point to a specific, serious failure and, ideally, to have documented it and put the counterparty on notice before terminating.

Because these exceptions are the main escape from the notice requirement, they are heavily contested. A terminating party will often plead the counterparty's misconduct, and the counterparty will characterise the same facts as an ordinary business dispute dressed up to avoid notice. If the court rejects the alleged grave breach, the immediate termination becomes a full rupture brutale, with damages calculated over the entire notice period that should have been given. The exceptions should therefore be relied on only where the breach is clear and provable.

Damages and how a foreign supplier limits its exposure

The measure of damages for a rupture brutale is narrower than many parties fear. The victim is not compensated for losing the relationship as such — the relationship could lawfully be ended. Compensation is for the abruptness: it is the profit the victim would have earned during the missing notice period, usually calculated as the lost gross margin (turnover less variable costs) over the difference between the notice given and the notice that should have been given.

So the damages depend on two things: how much notice was owed, and the victim's margin on the lost business. Additional heads of loss can be claimed where the abrupt rupture caused specific consequential damage — redundancies, stranded stock, or dedicated investments that cannot be redeployed — but the core award tracks the notice shortfall. Keeping the notice period defensible is therefore the single most effective way to control exposure, because it caps the period over which margin is lost.

A checklist for exiting a French relationship safely

For a supplier or buyer based outside France, the jurisdictional angle matters. A rupture brutale claim brought in France against a foreign party raises questions of international jurisdiction and applicable law; the Court of Justice of the European Union has treated such claims as contractual for the purposes of allocating jurisdiction within the EU where a tacit contractual relationship exists. Planning your exit with those rules in mind — alongside terminating a sales contract for breach — is what turns a dangerous rupture into a controlled one.

Frequently asked questions about rupture brutale in France

What is rupture brutale?

It is the abrupt ending of an established commercial relationship without sufficient written notice, penalised by Article L442-1 of the Commercial Code. The wrong is the suddenness, not the decision to stop dealing. A party can lawfully terminate a relationship and still owe damages for doing so without enough notice.

Does rupture brutale apply outside franchising?

Yes. It applies to any established commercial relationship — supply arrangements, distribution, sub-contracting, private-label manufacturing and long-running services — whatever the label. A relationship built only on a stream of repeated purchase orders, with no written contract, is fully covered.

How much notice must I give?

There is no fixed period. The notice must reflect the duration of the relationship, trade usage, economic dependence and the difficulty of finding alternatives. Longer and more dependent relationships require longer notice, and the notice must be honoured in full on normal terms.

What is the 18-month rule?

Since the 2019 reform of Article L442-1, a party who gives eighteen months of written notice cannot be held liable for insufficient notice. It is a safe-harbour ceiling: it protects you if you actually give that much notice, but it does not mean eighteen months is required in every case.

Can I end a relationship immediately for breach?

Yes, in two situations only. No notice is required where the other party has committed a sufficiently serious non-performance, or where force majeure makes performance impossible. Both exceptions are read narrowly, so document the grounds before relying on them.

Is cutting volumes a rupture brutale?

It can be. Article L442-1 catches a relationship broken off even in part, so a steep unilateral cut in orders, the withdrawal of a territory, or a sudden worsening of terms can be a partial rupture requiring proportionate notice. Ordinary fluctuations in volume are not caught.

How are rupture brutale damages calculated?

Damages compensate the abruptness, not the loss of the relationship itself. They are usually the lost gross margin over the notice period that should have been given but was not. Extra consequential losses, such as stranded investments or redundancies, can be added where proved.
