Iona MitchellSenior Associate & Advocate

Iona Mitchell


I’m a Senior Associate in our Guernsey Litigation practice, dealing with a wide range of complex commercial disputes, including Contentious trusts, Financial services litigation, Enforcement action by the Guernsey Financial Services Commission, Insolvency and Litigation with cross-jurisdictional aspects.

In 2019 I spent eight months on secondment at a multi-jurisdictional fund administrator and corporate services provider in Guernsey, giving me great insight into the industry.

I’ve dealt with various forms of dispute resolution, including ADR and mediation.

Prior to joining Mourant Ozannes, I spent over four years at Scottish commercial firm Brodies with a particular focus on professional indemnity litigation.

I’ve been a part-time tutor on the Contract Law and Unjustified Enrichment undergraduate course at the University of Edinburgh, and I continue to act as a guest seminar leader on an ad hoc basis.

I have also been a volunteer legal adviser at Citizens Advice, in Edinburgh and Guernsey, since 2012.
