This timely book offers a comprehensive exploration of the issue of transaction avoidance in the European Union (EU). Contributing to the formation of harmonised avoidance rules in the EU, it analyses the existing transaction avoidance regimes in cross-border scenarios as provided by the Recast European Insolvency Regulation and other EU regulations. Combining a private international law approach with substantive rules of transaction avoidance to improve the EU insolvency system, Oriana Casasola examines the theoretical framework of transaction avoidance and harmonisation. Comparing the avoidance actions available within and outside of the insolvency proceedings in England, Germany and Italy, chapters propose an alternative harmonisation of the transaction avoidance rules which fits within the current EU private international law framework. The book concludes by addressing the European Commission's Directive for the harmonisation of certain aspects of insolvency law and evaluates the possible issues emerging from the proposed rules. Offering solutions for harmonisation of existing transaction avoidance regimes, this book will be essential reading for students and scholars of company and insolvency law, corporate law and governance, and EU law. It will also be beneficial for legal practitioners and policymakers interested in international insolvency law.
