‘I think what distinguishes me and my colleagues at Barry.Nilsson. from many other lawyers working in family law is that we are pragmatic and don’t simply follow the process. I know that clients are looking for value in the fees they pay to their lawyer, so I’m very focused on quickly identifying the problems and drawing out the key issues in every case I’m working on and trying to fix those, rather than spending time on the extraneous matters. While I approach every matter strategically, I also make sure I treat everyone as an individual, because every case – every situation – I work on is different. Finally, I never sugar-coat advice. I am totally up-front with my clients. That’s important in family law.’
Geoff is dedicated to providing outstanding legal advice to his clients. He specialises in:
- Multi-jurisdictional and cross-border disputes
- Complex financial matters, including those with corporate entities, third parties and trusts
- International parenting matters.
Geoff has a particular interest in child abduction law, including its international aspects, and has published widely on this topic.

He is also one of the contributing authors to the International Parental Child Abduction Handbook published by the Family Law Section of the Law Council of Australia, with the support of the Commonwealth Attorney-General’s Department. This publication brings together a comprehensive of helpful and practical information to help legal practitioners help their clients to navigate all aspects of the issues which accompany international parental child abduction proceedings.
In his former role as Chair of the Board of the World Congress of Family Law and Children’s Rights, he was responsible for leading the 2017 Congress in Dublin. The Congress brings together organisations and individuals with a common interest in actively promoting and protecting the human rights of children and young people.
