The termination of commercial contracts is notoriously tricky. Whether it takes place behind-the-scenes, during the initial negotiations or a posteriori in front of a judge, disputes between co-contracting parties tend to amalgamate around this central point of concern.
The French Code of Commerce has codified the laws surrounding the practices of conducting an abrupt and abusive termination of established commercial contracts (Art L442-1 : link to https://www.legifrance.gouv.fr/codes/article_lc/LEGIARTI000038414278/2019-04-26/). Article L442-1 of the Code of Commerce sets out the country’s specific legal provisions in regards to the necessary conditions for terminating an established commercial relationship. There are straight-forward notice periods set out in these regulations, as well as notable limitations regarding rules of EU Competition law.
Wrongful or abusive termination of established commercial contracts are regulated by the principle of appropriate notice. These provisions do not intervene however in situations of breach of contract or of force majeure.
Before entering into a commercial contract in France you will want to spend a decent amount of time studying the specifics of the French Code of Commerce (link: https://www.legifrance.gouv.fr/codes/article_lc/LEGIARTI000038414278/2019-04-26/).)
