This volume considers the right to claim for return by the impoverished donor according to § 528 BGB (German Civil Code), which has increasingly shifted into the spotlight and represents an important intersection of civil and social law. While adhering to the highest academic requirements, this work remains focused on the needs of those in practice - whether it be in the form of a creditor with the right of recourse, the affected attorney specialized in inheritance law, social law or administrative law - and provides case presentations for orientation.
