"The partner all others aspire to emulate"
Overview
Overview
A Jersey Advocate and Partner, I specialise in commercial litigation, principally involving contentious and non-contentious trust cases. I’ve written and lectured about these topics around the world.
In 2017, I was elected as an Academician of the International Academy of Estate and Trust Law in recognition of my contribution to the profession.
As the Chair of Mourant Group, a role I assumed on 1 February 2025, I am responsible for Board effectiveness and engagement with shareholders and stakeholders. Previously, I served as the firm’s Senior Partner.
I’ve been a Partner since 1996 and previously served as Managing Partner of the Jersey Office and President of the Law Society of Jersey between 2014 and 2017.
