VON THUNEN | Rechtsanwaltsbuero

The lawyer´s office VON THUNEN advises family enterprises, entrepreneurial families and foundations in questions of strategic relevance. These comprise, inter alia, “classics” like business successions within the family, by sale or by establishment of a foundation as well as new challenges like the legal organization of a number of family shareholders with regard to the business („family business governance“), the internationalization of the family shareholders´ personal legal relationships or issues arising from an altered financing environment or with regard to employees´ participation rights.


We pursue a holistic approach addressing the interface of family and business, always viewing the individual economic and personal concerns of our clients in the wider context of the whole family and the entire family wealth. Given that in a family business these fields of law interact closely, our consulting approach integrates company, partnership and tax law as well as inheritance law and family law. Apart from our special experience derived from the year-long exclusive service to family businesses, entrepreneurial families and foundations, we embrace psychological and economic aspects actively. This interdisciplinary specialization proves its worth also in situations where a foundation acts as owner or when advising private clients with complex wealth.


We foster a style of proactive advice. Working trustfully, in particular, with our clients´ permanent tax and legal advisers, we maintain close personal relationships to further advisers with complementary specializations – also  internationally – in order to offer the best possible service to our clients together.  


The range of services offered by the lawyer´s office VON THUNEN comprises the following practice areas in which we have many years of experience:


  • Legal Foundations of the Family Business („Family Business Governance“)
  • Business Succession Planning
  • Reorganization of Corporate Groups and Legal Form
  • Sale and Purchase of Enterprises (Mergers and Acquisitions, M&A)
  • Financing and Capital Markets
  • Corporate Law Special Projects and Counsel to the Corporate Organs
  • Law and Practice of Foundations/Trusts
  • Structuring and Protecting Private Wealth („Asset Protection“)
  • Dispute Resolution in Family Businesses and Foundations/Trusts


The office VON THUNEN renders its services to family businesses, entrepreneurial families and foundations all over Germany and is represented by an office in Stuttgart and Bielefeld, respectively. Both cities and their wider regions are characterized by a marked presence of family businesses.


In Addition, we advise international entrepreneurial families and private clients with regard to their activities and investments in Germany. At their option, we advise our clients personally at their place of residence or business.
