Family Offices and Ultra-High-Net-Worth Individuals

The CMS Disputes Team represents ultra-high-net-worth individuals, single and multi-family offices in high stakes litigation and arbitration.  Much of our work has an international dimension and involves close collaboration with our CMS colleagues throughout the globe.  We are results driven, providing pragmatic advice that is targeted to achieving our clients’ strategic objectives.

Our experience includes:

  • A US$15m dispute over the validity of redemptions under a Cayman Islands master/feeder structure.
  • Disputes covering a broad range of asset classes from investments in real estate funds to disputes concerning yachts and aircraft.
  • Numerous multi million pound insurance claims, to include everything from real estate to blood stock.
  • HMRC investigations and enquiries, to include failed mitigation schemes and cases before the Tax Tribunal.
  • Professional negligence claims against Jersey based trustees.
  • A contentious exit from existing family office and investment management services and support in securing all necessary data for establishment of a new office.
  • A claim in relation to inappropriate investment strategies and service delivery.
  • Ultra-high-net-worth individuals on international fraud and asset recovery cases.
