  • Services

Oscar advises on complex trust, private wealth and chancery disputes, usually with an international element. He has particular experience acting for claimants in court applications offshore, working closely with a wide network of offshore practitioners to achieve successful outcomes for his clients. His recent offshore experience includes a successful mistake application in Jersey which deployed a number of novel jurisdictional arguments.

Oscar advises corporate trustees, investment advisors, dynastic families and entrepreneurs on breach of trust proceedings, applications to set aside transactions, pre-action disputes within the trust, investment loss cases and tax disputes. He also has experience advising fiduciaries on the impact of the Russia sanctions on the structures they administer.

Many of Oscar's cases involve taxation issues and/or dispute with HMRC and he works closely with the firm's private wealth team, as well as members of the tax bar, to advise on these aspects.
