Wills and Inheritance Disputes


  • Challenging the validity of a will
  • Trustee disputes
  • Pursuing and defending inheritance claims
  • Disputes with executors

Mark is an associate member of The Association of Contentious Trust and Probate Specialists (ACTAPS) and the extensive training undertaken through ACTAPS demonstrates his broad knowledge and ability to undertake the complex issues surrounding will and inheritance disputes.

His vast 26 years’ experience in family law means that he has an understanding and sympathetic approach to what can be a very difficult and upsetting time for the family. His background as a mediator means that he is focussed on reaching resolutions and an efficient and cost effective manner.

In 2015 Mark was interviewed by Sky News regarding the landmark contentious probate case Ilot v Mitson , where the Court of Appeal ruled that a disinherited daughter should be awarded a one third share of her mother’s estate despite the mother’s express wishes to the contrary.
