The fourth edition of Understanding Bankruptcy continues to provide a detailed introduction to bankruptcy and related state and federal debtor-creditor law. It will be helpful for students taking an introductory Creditors' Rights course that emphasizes bankruptcy; a free-standing Bankruptcy course; or an advanced course in Chapter 11 Reorganization. This edition includes explanations of the growing number of Court of Appeals and Supreme Court decisions interpreting changes made to the Bankruptcy Code nearly fifteen years ago in the Bankruptcy Abuse Prevention and Consumer Protection Act of 2005. Both new and experienced bankruptcy lawyers will find Understanding Bankruptcy helpful and insightful.
