The case collection is aimed at students who are dealing with legal obligations - both beginners and advanced students as well as exam candidates. Through 30 cases that address typical issues in the areas of tort law, unjust enrichment law, and the law of unauthorized management, students are shown how to apply the abstract knowledge acquired in lectures to claims analysis. The structure of claims and the techniques for solving cases are discussed in detail. All case solutions are presented in a legal opinion style and include structural guidance. The case analyses are supplemented by in-depth notes that facilitate students' review of the individual problem areas.
