Susan is a highly regarded family law specialist representing clients in divorce proceedings where there are substantial assets and cross-border disputes.

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.
