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.

Testimonials
Collated independently by Legal 500 research team.
- I think they are the largest dispute resolution team on the island. They are very well organized as a team, very responsive, and have a number of talented lawyers at all levels of the team. One of their strengths is the depth of their team.
- Jonathan Speck is the difference.
- Jonathan Speck has the respect of the court and his peers. His advocacy is clear and concise. He has the ability to cut through the nonsense and articulate in a manner that is understandable.
- We have worked with Mourant, Jersey, on some of our most significant matters for clients with assets of hundreds of millions of dollars, and more often billions, for over 20 years. The overall level of service is superb. They are first-rate and always our first choice. They are always swiftly responsive, provide sophisticated, tailored advice, and have great strength and depth on their team. I have worked with several of the partners on numerous client matters over the years and have found their associates to be knowledgeable and talented. They are uniformly a delight with whom to work.
- On the contentious dispute resolution matters, I have worked the most with and think very highly of Jonathan Speck, Bruce Lincoln, and Katie Hooper. Each is extremely knowledgeable, dedicated, and hard-working, sophisticated in their practice, and displays valuable judgment. Jonathan Speck is, of course, a recognized international star to whom we consistently turn, who always delivers the highest quality strategic advice. He is both a brilliant litigator as well as a non-contentious planning expert you always want on your side. Jonathan’s reputation and practice are truly global. He is well known as “the man to see” in Jersey on all legal matters, not just trust litigation. Bruce Lincoln is a superb trust litigation lawyer, who is tenacious in court and in all aspects of disputes, but who also finds swift, creative solutions to difficult, unusual problems. Katie Hooper is a forceful, strategic, creative trust litigator. We are working closely with her on major cross-border trust litigation for a well-known European family, and her work has been superb.
- Standout Jersey practice which has top-notch litigators of the highest quality, with decades of experience.
