Katie Hooper


I’m Counsel, a Jersey lawyer and an Advocate of the Royal Court of Jersey for our Litigation & Dispute Resolution practice.

I am an experienced advocate and have appeared before the Royal Court on many occasions in contentious matters. I practised at the Bar of England and Wales from 2009 – 2012 and 2017 – 2019 and, during that time, I appeared regularly before the County Court and High Court, in a wide range of applications, case management hearings and trials. Therefore, I have honed my legal skills both at the chancery commercial bar of England and Wales and my busy international litigation practice in Jersey.

I have experience in a broad spectrum of litigation matters, including contentious trusts and private client, insolvency, banking and professional negligence. I have acted in complex and high-value trust and commercial litigation in Jersey, both as the lead advocate and as part of a wider team. I have previously been named as one of eprivateclient's Top 35 Under 35.

I joined Mourant Ozannes in 2012. Having been an Associate, then a Senior Associate in the Litigation team for 5 years, I became a Consultant for the Litigation practice in 2018. In 2019, I became Counsel in the Litigation team in Jersey.
