Effective creditor/debtor rights and insolvency systems are an important element of financial system stability. The World Bank Group accordingly has been working with partner organizations to develop principles for insolvency and creditor/debtor rights systems. The Principles for Effective Insolvency and Creditor/Debtor Rights Systems (the Principles) are a distillation of international best practice on design aspects of these systems, emphasizing contextual, integrated solutions and the policy choices involved in developing those solutions.Based on the experience gained from the use of the Principles, and following extensive consultations, the publication has been thoroughly reviewed and updated in 2005, 2011 and 2015. The revised Principles contained in this document have benefited from wide consultation and, more importantly, from the practical experience of using them in the context of the Bank's assessment and operational work.
