How to choose the most beneficial enforcement regime for cross-border claims of a client? A question considerably complicated by (1) the existence of various European Union enforcement tools and (2) particularities in the national legal systems that impact on the operation and suitability of the various enforcement tools.This book compares and analyses the practical utility and potential pitfalls of the 2nd generation regulations (European Enforcement Order, European Order for Payment, European Small Claims Procedure and European Account Preservation Order) and their relation to Brussels Ibis. Further, it analyses whether and to what extent all of the 2nd generation EU regulations prove their worth in the cross-border enforcement of claims, and which measures can be recommended for their practical improvement and for achieving greater consistency in European enforcement law.The work is based on an extensive evaluation of case law (more than 500 published and unpublished judgments), empirical data (150 interviews with practitioners) and literature from eight Member States (Belgium, France, Germany, Italy, Luxembourg, The Netherlands, Poland, Spain) and the Court of Justice of the European Union. It provides an extensive and up-to-date picture of the cross-border enforcement of claims across Europe and is an important resource for academics and practitioners alike.
