Following the great success of the first three editions, the 'Lawyer's Handbook on Insolvency Law' is now fully revised in its fourth edition. The diverse case law that has emerged since the previous edition has been completely incorporated. Additionally, the COVID-19 pandemic and the long-overdue implementation of the EU directive on a preventive restructuring framework have compelled lawmakers to undertake extensive activities: all new regulations, including the SanInsFoG/StaRUG, the law for further shortening the residual debt discharge procedure, and the law for mitigating the effects of the COVID-19 pandemic, have been integrated into this new edition. Along with the significant need for updates, the author team has expanded. Despite all the necessary renovations, the core qualities of the work have not only been maintained but have also been further emphasized: the 'Runkel/Schmidt' consistently offers the reader both perspectives, that of the advisor on the debtor or creditor side as well as that of the insolvency administrator. Clear indications help to avoid liability risks and typical mistakes. Tips on strategy and tactics in insolvency cases enhance the practitioner’s know-how. Examples, checklists, overviews, and sample formulations ensure that crucial aspects are not overlooked. In short: this book provides the reader with everything they need to achieve the best outcomes for their clients.
