Our team of professionals specialise in a broad spectrum of legal areas. Including Family Law, Collaborative Law, Deceased Estates, and Mediation and Family Dispute Resolution (FDR). We stand ready to address your specific needs, offering proactive and comprehensive support throughout your journey.

Unlike traditional firms, we offer a private and supportive space to discuss how we can address your particular needs. When required, we will use family-friendly processes and if needed, will talk to your support network and your former partner’s lawyer. If you need tough representation in court, our Northern Beaches firm will be there to help guide you.

Our first choice in separation and divorce however, is to use alternative methods. We engage other professionals such as mediators, financial advisors and counsellors to assist you and your family to get through this difficult time.
