I have nearly 15 years’ experience in succession law and lead Thynne + Macartney’s Private Clients team.

My practice involves all three areas of succession law: estate planning, estate administration and estate litigation. Although my “first love” will always be assisting clients with estate disputes, I long ago realised that the very best way to do this is a considered plan, that is carefully executed.

I also have considerable skills and training in alternative dispute resolution including mediation and collaborative law. These skills are also part of my practice in both estate administration and estate planning as I assist families to work through issues which are often complex, delicate and contentious.

My clients include individuals, private and public companies, trustee companies, accountants, financial advisers, charities, and other legal firms and their clients.

I have a particular interest in the education of the legal profession. I am currently a member of the QLS Succession Law Specialist Accreditation Advisory Committee and have taught components of the University of Queensland Master of Laws course (estate litigation and estate planning) and Bachelor of Laws course (succession law).

I am delighted to lead a team with considerable depth and experience, including three Queensland Law Society Accredited Specialists in Succession Law and one an Accredited Specialist in Family Law, making it one of the most qualified teams of its kind in Queensland.



Karen is a Queensland Law Society Accredited Specialist in Succession Law.
