Asymmetric jurisdiction clauses are clauses which contain different provisions regarding jurisdiction for each party. They are widely used in international financial markets. However, the validity of this form of agreement has been called into doubt in several European jurisdictions. Furthermore, following Brexit, there may well be an increasing focus on alternative methods of enforcement under the Hague Convention and at common law, claims for damages and anti-suit injunctions. As well as considering recent developments in the case law and the implications of Brexit, this article will emphasize that all of these questions can only be answered after the individual promises contained in any particular agreement are properly identified and construed. Once that is done, there is no reason why the asymmetric nature of a clause should be a bar to its enforcement.
