Sudden Termination of Commercial Relationships: Lawyer in Paris

The sudden termination of an established commercial relationship is one of the most frequent disputes between companies doing business in France. Article L. 442-1, II of the Commercial Code makes liable any party who terminates, even partially, an established relationship without written notice reflecting its duration and trade practice. The rule applies to foreign suppliers and distributors dealing with French partners. The firm acts for victims of termination and for companies wishing to end a relationship while limiting their exposure.

The question is almost never the right to terminate, which always exists, but the notice period and its proof.

The risk: a legitimate termination that becomes a debt of several months of margin

For the terminating party, the risk is being ordered to compensate the gross margin the partner would have earned during the notice period that should have been granted: twelve, eighteen, sometimes twenty-four months for long-standing relationships. Since the ordinance of 24 April 2019, a party who has granted eighteen months’ notice can no longer be held liable on this ground, which finally provides a benchmark.

For the victim, the risk is letting time pass: evidence of the established relationship (turnover, correspondence, dependence) fades, and the action must be brought before one of the specialised courts designated by the Code, on pain of inadmissibility. A writ served on the wrong court loses months.

The legal solution: proving the established relationship, calculating the notice, choosing the right court

The victim must show an established relationship, that is a regular, stable and habitual one, then a sudden termination, that is without sufficient written notice. Loss is calculated on the margin on variable costs lost during the missing notice period, not on turnover. Case law takes into account seniority, the degree of dependence, the specificity of the products and the time needed to find a replacement partner.

The terminating party protects itself through anticipation: written notification, proportionate notice, maintenance of commercial terms during the notice period, and documentation of the partner’s breaches where termination is justified by serious misconduct, which dispenses with notice. These situations often overlap with abuse of economic dependence, on which the firm has published a practical guide.

How the firm assists you

For the victim, the firm reconstructs the history of the relationship, quantifies the loss with the accountants, sends a detailed formal notice and brings the action before the competent specialised court, in summary proceedings where provisional continuation of the relationship is necessary for the company’s survival.

For the terminating party, it audits the relationship before the decision, drafts the termination notice, sets the notice period, organises the evidence and, if a compensation claim arrives, contests it on the grounds of the established relationship, the partner’s fault or the calculation of loss. It also addresses international relationships, where the application of Article L. 442-1 depends on the applicable law and the competent court.

Typical matters

The situations below are illustrative scenarios drawn from the firm’s practice and anonymised.

Subcontractor delisted after fifteen years

An automotive subcontractor loses within three months a principal representing 60 % of its business. The firm obtains in summary proceedings the partial continuation of orders and, on the merits, compensation equal to eighteen months of margin.

Distributor wishing to change supplier

A distributor wants to replace a long-standing supplier. The firm organises the termination: notification, twelve months’ notice with volumes maintained, transition timetable. No proceedings follow.

Drop in orders disguised as partial termination

A customer cuts its orders by 70 % without notification. The firm characterises the partial termination, quantifies the loss and obtains a negotiated settlement.

The termination is rarely the only claim. The unpaid balance of the relationship is recovered under commercial debt recovery, and where the partner was economically dependent, article L. 420-2 adds a second ground.

Frequently Asked Questions

What does French law require before ending a commercial relationship?

Where a commercial relationship is established, meaning regular, significant and stable enough to create a legitimate expectation that it would continue, it cannot be brought to an end abruptly. The party ending it must give written notice of a length having regard to the duration of the relationship and to trade practice. The provision of the Commercial Code that carries this rule was recast in 2026, so wording and benchmarks taken from contracts and precedents predating that reform should be checked against the current text before they are relied on.

What notice period is sufficient?

There is no tariff. The answer is built from the duration of the relationship, its volume, the degree of economic dependence, the specificity of the investments made and the time reasonably needed to find an equivalent replacement. The statutory scheme sets an outer limit, and a notice period complying with it protects the party ending the relationship. Contractual notice does not settle the question on its own: a short contractual period does not authorise a short actual one where the relationship has run for many years.

Does the rule apply to a foreign partner?

It can. French courts have applied it in international situations sufficiently connected with France even where a foreign law governed the contract, treating the rule as protecting the market rather than only the parties. A foreign supplier terminating a French distributor, or a French buyer ending a long relationship with a foreign supplier, should not assume that a choice of foreign law removes the exposure. Where the relationship is genuinely foreign in every respect the analysis differs, and it is carried out before the letter is sent.

When can a relationship be ended without notice?

Where the other party has committed a sufficiently serious breach, and where force majeure prevents performance. The breach must be real and proportionate to an immediate termination, and it is judged on what was known at the time, so the reasons stated in the letter are the ones that will be examined. A gradual reduction in volumes can itself amount to a partial termination without notice, which is a frequent and expensive surprise for a party that believed it was simply buying less.

How is the loss calculated?

By the margin lost during the notice that should have been given, computed on the gross margin over variable costs for that period, rather than by the loss of the relationship as a whole. Separate heads of loss may be added where they are proved: stock left on hand, redundancy costs, specific investments that have lost their purpose. The calculation is arithmetical and the accounting evidence decides it, which is why the accounts of the relationship are prepared before the claim is quantified.

Which court hears these claims?

A limited number of specialised commercial courts have exclusive jurisdiction over claims based on restrictive practices, with appeals going to the Paris Court of Appeal. Filing before another court leads to the claim being declared inadmissible or transferred, with the delay that follows. Where an arbitration clause exists, the arbitrators may hear the claim. Identifying the right forum is therefore the first step, and it is a point on which files are regularly lost before the merits are ever reached.
