Family Law

We are one of the most experienced Family Law practices on the north shore of Sydney, if not in Sydney itself. We are well respected and highly regarded with a wide network of referrers from many parts of the community.

Whether you need assistance in a property settlement or in addressing issues surrounding children; whether your questions are around child support or there has been violence in your relationship; whether your issue is complex or simple; we have the knowledge and background to help you.

Family law matters are often very sensitive and challenging. Rarely are they easy for you personally. We see it as part of our role to support our clients through every stage of the process which will usually be a pathway of resolution through negotiation and/or mediation. In some particular cases a client will experience a level of involvement with a Court. Whatever the pathway, we have the necessary skill set to handle your matter.

We also represent a wide array of commercial lenders, so that when our clients want to “do business”, they can move quickly and efficiently.
