Estate Litigation The Effective & Resilient Representation You Need

Estate Litigation Attorney in Chicago

Contested Estates, Will Disputes & Executor Claims in Cook County

When a decedent’s estate becomes a legal battleground, disputes rarely stay simple. Will challenges, executor misconduct, and asset distribution fights all demand an attorney who can move quickly and argue effectively in the Cook County Probate Division. At Regas & Dallas P.C., we’ve represented Chicago clients in probate and estate administration conflicts since 2003, bringing over 115 years of combined legal experience to every matter we handle.

What distinguishes our approach is the commercial litigation foundation behind it. When a disputed estate includes a family business, LLC interest, or investment real estate, we bring the same depth we apply to partner disputes and commercial real estate litigation. This capability matters in cases where most estate-focused firms reach their limits.

Estate disputes move on deadlines. Call our estate litigation attorneys at (312) 702-1809 or reach out online for same-day follow-up.

Estate Disputes We Handle

Estate litigation refers to contested legal proceedings arising from the administration of a decedent’s estate. That covers a range of dispute types, and we represent both claimants and fiduciaries depending on the situation.

  • Will Contests: We pursue and defend challenges to a will’s validity based on lack of testamentary capacity, undue influence, fraud, or improper execution under Illinois law.
  • Executor and Personal Representative Misconduct: When a personal representative mismanages estate assets, engages in self-dealing, or fails to distribute as required, beneficiaries have the right to act. We also defend executors facing unfounded removal petitions.
  • Estate Accounting Disputes: We demand complete accountings of estate assets and challenge figures an executor has reported when those numbers don’t hold up.
  • Estates Involving Business Interests or Real Estate: Closely held businesses, LLC interests, and commercial property in Chicago and Cook County create layered disputes that require both fiduciary and business governance analysis. This is where our commercial practice directly supports our estate litigation work.

Estate disputes are governed by the Illinois Probate Act, which sets out the rights of heirs, the duties of personal representatives, and the procedures for contesting a will or removing an executor.
