Jurisdiction
Which court has jurisdiction?
Within the EU this is governed by the Brussels IIb Regulation – above all through habitual residence.
VO (EU) 2019/1111, applicable to proceedings from 1 August 2022 and in force in all Member States except Denmark. Art. 3 lists the possible connecting factors – what matters above all is the habitual residence of the spouses, alongside their nationality.
Whoever files first determines the forum. If the courts of several states have jurisdiction at the same time, the court seised later stays its proceedings (Art. 16 et seq. Brussels IIb Regulation). This race sometimes decides more than any question of substance.
