'The Princely House of Liechtenstein and its Family Property Law': The study examines the structure of family wealth in the Liechtenstein princely family. Unlike other families, the Princely House is a legal entity with a private law power to regulate based on its house autonomy. This special status under private law is based on a ¿Privatfürstenrecht¿, a private law regime for families of the high nobility, which shaped the state, economy, and society in German-speaking legal systems until the end of monarchies at the beginning of the 20th century. It has survived to this day in Liechtenstein despite the many historical upheavals - thanks in part to a dualistic constitution that preserves monarchical roots and combines them with powerful (direct) democratic elements.
