The compendium by Lorenz is the go-to resource for students and early career professionals. Many typical practice cases with solution hints from later professional life make the dry normative contexts comprehensible, thanks to numerous examples and overviews. The fourth edition further deepens the integration into practical, application-oriented case work. This makes it clear why certain rules from the BGB are needed and how civil guardianship and maintenance law relates to public child and youth welfare law. The new regulations on long-term guardianship and procedural representation are explained immediately, and particularly conveniently, the legal status as of January 1, 2023, is also clarified.
