 The European Commission promulgated the Brussels II regulation in March 2001 to settle which court of an EU member state was competent to hear cases related to divorce between the members of the European Union.This regulation, amended in 2005, determines which courts will have jurisdiction over what matters.But this regulation, which binds all member states save Denmark, does not address which law EU courts should use, and due to the large diversity in divorce laws in the EU, the results may vary strongly depending on which law is used.
