About
Provided by Arendt & Medernach
To preserve our clients’ wealth now and for the next generation, Arendt has assembled a multi-disciplinary Private Clients team that covers all aspects of wealth structuring from a corporate, real estate, civil and estate perspective, as well as a tax law standpoint.
Our assistance includes the design and implementation of wealth holding structures, using a comprehensive range of tools such as corporate vehicles, regulated investment funds and life insurance policies.
For international families, we provide advice on private law and inheritance issues in their respective jurisdictions, including any cross-border aspects. In recent years we have been involved in the administration or liquidation of several large international estates.
In addition, our Private Clients litigation team has significant experience in sophisticated domestic and multi-jurisdictional estate disputes. Although we always seek an amicable resolution, notably through mediation, we are ready when necessary to defend the interests of our clients in court in all kinds of estate-related disputes, including:
- Challenges to the validity of wills
- Forced heirship statutes, clawback of donation, restoration or accounting of gifts
- Actions for statement of accounts
- Disputes involving family businesses
- Investor and shareholder disputes
