Overview

I’m a Partner of Mourant Ozannes (Jersey) LLP in our Jersey Litigation practice, and part of our specialist financial services and regulatory team as my primary focus is on regulatory work.

My work includes advising on compliance with the regulatory laws, anti-money laundering regime, sanctions, information requests and data protection.

I’m also experienced in dealing with contentious employment matters and insolvency issues. In recent years, I’ve acted in a number of leading cases on challenges to TIEA notices and advised on mis-selling claims against banking institutions.

I am part of a team of specialists advising businesses on data protection matters including working with clients to ensure that their policies, procedures and third-party contracts can demonstrate compliance with data protection legislation, drafting information notices to meet the required standards of transparency and advising on the legality of international transfers of personal data.
