For over 30 years Cathie has practised exclusively in family law and disputes.
Her work has focussed on primarily financial and property matters for married, de-facto and same sex couples. She is expert in resolving complex family financial arrangements and has extensive experience in dealing with parenting matters.
While it is often said the majority of a family lawyer's work may be at the end of the relationship, Cathie also advises clients who are preparing for cohabitation and drafts financial, or pre-nuptial agreements under the Family Law Act and the Property (Relationships) Act.
Cathie is widely lauded for her sensible and pragmatic approach to family law and is known for driving effective settlement negotiations and encouraging alternatives to traditional Court processes.
Cathie has written and presented many papers on family law issues for continuing professional legal education (including on the relationship between bankruptcy and family law and binding financial agreements).
She is a member of the Family Law Section of the Law Council of Australia and a member of Law Asia. For many years she was a member and, later, the Convenor of the Family Law Section of the City of Sydney Law Society.
Cathie was admitted as a solicitor in New South Wales in July 1988 and commenced practice in a busy suburban family law firm, conducting a wide variety of family law and related work.
In January 1996 she commenced as Senior Associate at (the then) Stuart Fowler & Associates and was appointed a Partner in 2000.
