Article 26
1. Apart from jurisdiction derived from other provisions of this Regulation, a court of a Member State before which a defendant enters an appearance shall have jurisdiction. This rule shall not apply where appearance was entered to contest the jurisdiction, or where another court has exclusive jurisdiction by virtue of Article 24. 2. In matters referred to in Sections 3, 4 or 5 where the policyholder, the insured, a beneficiary of the insurance contract, the injured party, the consumer or the employee is the defendant, the court shall, before assuming jurisdiction under paragraph 1, ensure that the defendant is informed of his right to contest the jurisdiction of the court and of the consequences of entering or not entering an appearance.
