This textbook provides an overview of the ordering of private legal relations implemented in the German Civil Code (BGB). Important institutes and individual legal regulations are explained on the basis of simple cases and the considerations involved in solving them, and this approach is used to illustrate the connections between legal regulations and the way in which they interconnect. The focus is on property law in the first three books of the BGB, but also with the range of issues involved in family law and inheritance law, which are important for interpersonal relationships.
