Since 2006, David has primarily been involved in larger property disputes in the Family Court of Western Australia and criminal trials through several criminal law jurisdictions. The issues facing David’s family law clients have included how detailed corporate structures (many of which encompass substantial property assets held overseas), family trusts, multi-generational farming lands and self-managed superannuation funds are to be divided subsequent to separation.

David continues to act as a barrister and solicitor in child-related matters in the Family Court. These matters have included grandparents seeking to spend time with their grandchildren; parties seeking to protect their children from a spouse with either mental health or addiction issues, and parties who seek to relocate (often internationally) with their children.

He has advised and appeared as Counsel in criminal and quasi-criminal jurisdictions, and specialises in the areas of criminal charges, traffic offences and Violence Restraining Orders. David has acted for clients in State Administrative Tribunal matters and commercial matters.
