LL.B., B.Ec.

Mark was admitted to practice in 1996 after obtaining Bachelor degrees in both Law and Economics from the University of Adelaide.

Mark worked in two of Adelaide’s leading law firms before starting his own firm, Jappe & Associates, specialising solely in wills and estates.

In 2013 Jappe & Associates merged with Adelta Legal, where Mark continues to offer specialist assistance with all aspects of wills and estates and in particular estate litigation.

Mark is well known for his work as a litigator, specialising primarily in contested estate matters in the Supreme Court.  Mark is commonly appointed by the Court to act as litigation guardian for parties who, due to either being minors or suffering from a disability, are unable to act on their own behalf.  He has also been appointed by the Court to administer deceased estates while potential beneficiaries engage in litigation.

He is particularly known both for his tenacity in litigation and for his practical and creative approach to resolving disputes.

Mark enjoys assisting clients with their estate planning and is experienced in obtaining grants of letters of administration and probate and assisting clients to finalise the estates of loved ones.

Mark can assist you with all wills and estate matters including:

  • estate litigation
  • wills and estate planning
  • probate and estate administration
  • powers of attorney and advance care directives.

He is a member of the Law Society of South Australia and has served on its Succession Law Committee since 2007.

Mark has been recognised by Doyle’s Guide as a preeminent estate litigation lawyer and as a leading estate planning lawyer.

Mark is also a nationally accredited mediator.  He primarily mediates matters involving contested estates or trusts, but is also available to mediate other types of disputes.

Outside of the law, Mark serves on the Board of the Mendelson Foundation, a charitable trust which awards scholarships to students who are resident in the West Torrens Council area.

When he is not busy assisting clients, Mark is a keen bridge player, having represented both his State and his country.
