About Us

Established in 2000 and located in Perth

O’Sullivan Davies is a premier Australian law firm practicing in the area of family law

The firm’s partners and solicitors are highly experienced and well regarded in the field. We adopt an innovative and client focused approach to all our work with a view to delivering responsive and meaningful solutions.

What makes us different?

Dynamic business practices coupled with our core values are the driving force and differentiators behind our dealings with clients, opponents and the Court.  Our core values, which we refer to in practise as “the OSD Way”, are:

  • Respect

We respect the Court, our clients and our opponents. 

  • Objectivity

We never make our professional disputes personal.  We empathise with our clients, but remain objective and open-minded.

  • Honesty and integrity 

We manage our clients’ expectations.

  • Difficult conversations

We tell it as it is, not how someone wants to hear it.
