Position

Susan is a highly regarded family law specialist representing clients in divorce proceedings where there are substantial assets and cross-border disputes. Further, she has particular expertise and interest in complex cases involving children, such as international relocation and provision for children with complex medical needs from married and unmarried families.

Susan regularly advises on complex financial remedy proceedings, Inheritance Act cases, pre-and post-nuptial arrangements and jurisdictional disputes. She also has keen interest in and experience in protecting vulnerable clients, particularly those who have experienced coercive control and other forms of domestic violence in their relationships and/or who need additional protection to ensure their safety and well-being during the course of proceedings.

When situations cannot be resolved amicably or in a commercial manner, Susan has extensive experience and a record of successfully litigating at the highest levels including the Court of Appeal.

Susan’s clients are generally wealthy individuals and ultra-high-net-worth individuals and their partners/spouses from a range of different professions and backgrounds, often with international financial interests and keen to avoid media exposure and/or reputational damage.
