You just received an odd-looking document in French, titled ASSIGNATION, which may, or may not be accompanied by an English translation. You, a Delaware corporation headquartered in California, are being sued before the Tribunal de Commerce of Paris!
This is the time to consult with a firm that will help you defend your case before French courts. First we will determine if the French court has jurisdiction over the case under the applicable rules of international law. Maybe, maybe not.
Then we help you decide whether you want to go to Court in France. With good legal representation, it may turn to your advantage to fight that fight there rather than in the United States.
