Abrupt termination of an established commercial relationship (L442-1): 2026 guide

Article L442-1, II of the Commercial Code prohibits abruptly terminating, even partly, an established commercial relationship without sufficient written notice. Breach makes the terminating party liable to compensate the resulting loss. The text appears on Legifrance and derives from the 2019 reform (2019 version).

What the law says (L442-1, II)

Abrupt termination is sanctioned where an operator ends (or substantially reduces) an established commercial relationship without written notice accounting particularly for the relationship's duration, industry practice and, where applicable, interprofessional agreements. The principle and criteria are available on Legifrance and widely discussed by practitioners (see explanatory guides on Livv.eu and here).

The 3 cumulative conditions

1) An established commercial relationship

It must be stable, ongoing and habitual, creating a legitimate expectation of continuity (e.g. distribution, subcontracting, SaaS/IT services, recurring supply). Useful indicators: significant duration, regular orders, stable volumes, joint planning, exclusivity, specific investments.

• Evidence: invoices across several financial years, order records, email correspondence, business plans.

2) Total or partial termination

Termination may be total (cancellation, delisting) or partial (abnormal volume reduction, withdrawal of a product range, substantial changes to terms: price, discounts, exclusivity, territory). An abrupt, unjustified change may be treated as compensable partial termination.

3) Insufficient (or no) notice

Notice must be written and proportionate, primarily considering:

• the relationship's duration and stability;
• trade practices and applicable interprofessional agreements;
• the partner's economic dependence and ability to adapt;
• the sector's economic conditions and seasonality.

In litigation practice, courts calibrate notice “case by case”; very long relationships often lead to double-digit periods. Practice rarely accepts notice exceeding 18 months, without this constituting a statutory rule (see practical reminders on Livv.eu).

Drafting written notice that holds up in court

The legislation requires writing. For evidentiary purposes and legal certainty, specify the notification date, end date and terms applicable during notice:

“Under Article L442-1, II of the Commercial Code, we hereby give you [X] months' notice. The relationship will end on [date], with current terms remaining applicable until that date.”

Faithful performance during notice (maintaining reasonable volumes/prices) drastically reduces the risk of an adverse judgment.

Exceptions: serious breach and force majeure

No notice is required for the other party's serious breach (established non-performance, fraud, safety/quality failures) or force majeure. The terminating party bears the burden of proof. Systematically document through incident reports, official reports, correspondence and prior formal notice. Useful operational good practice is outlined on Entreprendre.Service-Public.fr.

How is compensation calculated?

Compensation aims to put the victim in the position they would have occupied with sufficient notice. The usual method uses lost gross margin (not turnover) over the missing notice period, potentially increased by reasonable adaptation costs.

• Basis: accounting data (gross margin by customer/segment), sales histories, order book.
• Exclusions: no double compensation or earnings already replaced by substitute customers.
• Watch the clauses: a limitation clause must not deprive Article L442-1, II of practical effect.

If the claim is not subject to serious dispute, an advance may be sought through interim payment proceedings.

Procedure and litigation strategy

1. Rapid audit: classify the relationship (established?), measure the extent of termination, estimate sufficient notice.
2. Formal notice and an attempt at mediation/conciliation to secure evidence and negotiate an orderly outcome.
3. Jurisdiction/court: validate any jurisdiction clause and its interaction with Brussels I bis (EUR-Lex). Practical court information: Justice.fr.
4. Deadlines: act promptly. For an overview of commercial time limits, see our commercial limitation periods guide.
5. Scenarios: liability proceedings on the merits (L442-1, II), potentially combined with contractual proceedings (wrongful termination). For indefinite-term relationships, compare commercial contract termination rules.

Practical cases and warning signs

• Distribution: sudden delisting or drastic order reduction without transition.
• Subcontracting/industry: withdrawal of a model/range representing most volume without sufficient notice.
• Services/B2B SaaS: termination of a framework agreement and overnight cessation of recurring volume (batches, sites, entities).

Early indicators: unusually extended payment terms, unilateral discount reductions, scheduling delays, silence on renewal. Respond with a summary email and, if necessary, a formal notice to preserve evidence.

Operational checklist

• Check the existence of an established relationship: duration, regularity, legitimate expectations (invoices, history).
• Identify the termination: total, partial or substantial change.
• Assess sufficient notice: relationship duration, practices, dependence, adaptation.
• Draft clear written notice (end date, transitional terms) and perform it faithfully.
• Document any serious breach if no notice is given (reports, official findings, formal notices).
• Quantify loss: missing gross margin, transition costs, supporting evidence.
