The recently recast Council Regulation No 2019/1111 (‘ Brussels II-ter’ ), which came into force in August 2022, is the key EU family law Regulation. It governs jurisdiction, recognition and enforcement in matrimonial matters (principally divorce), matters of parental responsibility (principally, custody and access), and international child abduction. This book provides an in-depth discussion of this complex Regulation. Written by three renowned experts, this comprehensive analysis benefits from the collective scope of their experience and knowledge not only of their jurisdictions (Italy, Sweden and the UK) but also more generally of international family law and private international law. Brussels II-ter: Cross-border Marriage Dissolution, Parental Responsibility Disputes and Child Abduction in the EU provides not only a clear exposition of the Regulation’s provisions, but also supplies a critical evaluation of these, highlighting the undoubted improvements made by Brussels II-ter while simultaneously exploring its more problematic aspects. An exposition of the relationship between the EU and the UK following Brexit concludes this volume.
