Trust & Estate Litigation

Trust and estate litigation impacts core relationships and family legacies. The stakes are high and the right attorney is critical. MM&R’s core practices include planning and litigating for both trusts and estates. We are respected leaders, well-versed in the substantive law and technical procedures that control these specialized cases. While many estate planners have never seen a courtroom, much less a trial, MM&R includes accomplished trial attorneys.

Even with the best planning, circumstances change and unforeseen issues may arise between family members. If they do, you can turn confidently to MM&R. We have successfully represented individuals, families, beneficiaries, heirs, legatees, executors, trustees, guardians, banks and trust companies in trust and estate litigation for over 35 years, and we look forward to representing you in matters including:

  • Will & Trust Contests
  • Contested Probate Matters
  • Guardianship Litigation
  • Asset Discovery & Creditor Claims
  • Petitions to Remove a Trustee or Executor
  • Will or Trust Construction
  • Will or Trust Reformation
  • Compelling Trust Distributions
  • Breach of Fiduciary Duty Claims
  • Tortious Interference with Inheritance Expectancy Claims
  • Personal Injury or Wrongful Death Estate Claims

We genuinely care about you and appreciate the emotional nature of these cases. We will listen to you to develop a strategy that best meets your needs, considering the potential for settlement, mediation, trial, appeal and emergency or injunctive relief where appropriate.
