This article-by-article Commentary on EU Regulations 2016/1103 and 2016/1104 critically examines the uniform rules adopted by the EU to deal with the property relations of international couples, both married and in registered partnerships. It offers a comprehensive side-by-side discussion of the two Regulations to provide context and a deeper understanding of the issues of jurisdiction, applicable law and recognition of judgements covered. Written by experts from a variety of European countries, this Commentary draws on scholarship and practice from a number of EU states to enrich its analysis and explore pertinent questions of jurisprudence. It also highlights the close relationship of the Regulations with other legislative measures of the EU in the field of private international law, such as on matters of succession and matrimonial matters. This Commentary will be a crucial reference source for practitioners working as family litigation lawyers, estate planning lawyers and notaries. It will also be of interest to scholars and other practitioners working in the field of private international law. Contributors include: G. Biagioni, A. Bonomi, B. Campuzano Diaz, J. Carruthers, S.
