Mourant is instructed by trustees and beneficiaries across a range of complex disputes, including breach of trust claims and applications to remove trustees or protectors. Alongside trusts expertise, the group is also tasked with overseeing commercial disputes and proceedings stemming from insolvencies. February 2026 saw Katie Hooper named practice leader, and she is well versed in trust litigation, but also handles banking and funds disputes. Jonathan Speck represents clients across disputes arising across trust lifecycles, from establishment to winding up, also the core of Bruce Lincoln‘s practice. Stephen Alexander is equally at home tackling trust litigation as he is partnership and fund disputes, while Justin Harvey-Hills is called upon for assistance in contentious blessing applications.
