MacKenzie A. Hyde


MacKenzie A. Hyde is a Member in the Litigation Practice Group of Clark Hill’s Chicago office. MacKenzie concentrates in contested guardianships, estates and trusts, as well as fiduciary litigation and estate administration.

Areas of Practice:

Estate, Trust, and Fiduciary Controversy: MacKenzie represents corporations and individuals in their fiduciary capacities (i.e., trustee, executor, administrator) as well as estate and trust beneficiaries in matters involving claims of breach of fiduciary duty, undue influence, lack of capacity, fraud, duress, and negligence.  More specifically, MacKenzie represents fiduciaries and beneficiaries in the following types of post-death estate and trust challenges:

  • Breach of fiduciary duty
  • Will contests
  • Trust contests
  • Tortious interference with an inheritance expectancy
  • Citations to recover assets belonging to an estate or trust
  • Claims against estates and trusts
  • Statutory Custodial Claims

MacKenzie’s extensive litigation experience in these areas allows her to effectively advise clients on estate planning techniques that will help their estate plans avoid being subject to such litigation during their lifetime or after their death. 

MacKenzie also represents corporate and individual fiduciaries and beneficiaries in uncontested estate and trust administration.

Guardianship and Power of Attorney Litigation and Administration: MacKenzie prosecutes and defends actions involving powers of attorneys and petitions for guardianship for adults with disabilities. MacKenzie has extensive experience litigating whether someone is a disabled person under the law and, if so, who should be his or her guardian of the estate and person.  In these matters, MacKenzie has represented both the petitioner and the alleged disabled person.  MacKenzie also litigates matters involving the enforceability of powers of attorney for health care and property, as well as actions alleging wrongdoing by an agent under power of attorney, which are often brought in conjunction with a guardianship proceeding.

MacKenzie represents corporate and individual guardians and has extensive experience representing guardians in litigation that arises during the administration of the estate, such as:

  • Requesting to create or amend a Disabled Person’s estate plan, including changes to beneficiary designations
  • Pursing causes of action on behalf of the Disabled Person, including financial exploitation
  • Defending claims filed against the Disabled Person
  • Petitioning to relocate a Disabled Person
  • Petitioning for a Disabled Person to be restored or the guardianship modified

MacKenzie’s extensive litigation experience in these areas allows her to effectively advise guardians, trustees, and agents under powers of attorney for health care and property as they manage the financial and personal affairs of a disabled person during the disabled person’s life.

MacKenzie is frequently appointed by judges in the Probate Division of the Circuit Court of Cook County to serve as a Guardian Ad Litem in disabled estates as well as counsel for alleged disabled persons.

  • In re Estate of Nina L., A Minor, 2016 Ill.App. LEXIS 701 (September 16, 2015) (vacating the trial court’s order and making the necessary findings of fact to allow client, Nina L., an undocumented immigrant, to file for Special Immigrant Juvenile Status, a case of first impression)
  • In re Estate of Donald Howell, 2015 Ill.App. LEXIS 466 (June 19, 2015) (reversing to allow client, the Guardian of the Estate, to propose an estate plan that deviates from intestacy for a disabled person who never had testamentary capacity in case of first impression)
  • Pontarelli v. Pontarelli, 2015 Ill.App. LEXIS 191 (March 18, 2015) (affirming multiple interlocutory orders in favor of client)

Eric Dorkin, MacKenzie Hyde and Ray Koenig obtained a significant victory in the 1st District Appellate Court. In a case of first impression, the Illinois Appellate Court granted Clark Hill’s emergency appeal in favor of Nina L., a minor seeking to apply for Special Immigrant Juvenile Status to stay in the United States following her 18th birthday.  The trial court had denied Nina L.’s request for the judicial findings necessary for her to apply to remain in the United States after being abandoned by her natural parents.  The trial court held that it was not proper for it to enter findings pursuant to federal statute.  The Appellate Court reversed and entered the required findings itself on an emergency basis so that Nina L. could timely file the required documents with the U.S. Citizenship and Immigration Services, as her 18th birthday was just days away.  

As reported in the local legal press, “This is a case that really mattered,” said Dorkin, who represented Nina L. “If the case was decided the other way, she was going back to Taiwan with no known family or connections and just a high school degree, and I think that’s a recipe for lifelong disaster.”
