WIFU Departments


The Chair of Family Business Law represents the juristic pillar of WIFU’s transdisciplinary research concept. Family business law is a relatively new legal field. The existence of family business law as a legal discipline in its own right is disputed in traditional jurisprudence. This is because the law itself does not recognise the term ‘family business’, so there are no express legal consequences to the existence of a family business at any point. But despite this, a family business is very particular from a legal viewpoint. Looked at from the point of view of civil law, the linkage between family and business interests impacts on how the company is treated legally. Firstly this is because the family business law cuts across different legal fields, and that itself is unique. Secondly, it is a subject that entails legal questions of its own, ones that only arise in this form in family businesses. And finally, the general instruments of civil law can be influenced by the particularities of family businesses.

Apart from that, the inclusion of family members in a business has far-reaching tax law consequences which constantly occupy these businesses, beyond the matter of succession itself. All of the developments in legislation, judicature and financial administration have to be monitored and legally tested. This is why WIFU aims, at its Department of Law for Family Businesses, not only to research the doctrines of family business law in full, but to make a continued contribution to the legal practice of family businesses in view of the ever-changing legal landscape.
