Guiding Families Through Probate With Experience, Clarity, and Compassion


Losing a loved one is hard enough—navigating the probate process shouldn’t make it harder.

Whether you’re the executor of a will or managing an estate without one, we’re here to take the legal complexity off your shoulders. With over 40 years of local experience, we understand the ins and outs of Illinois probate law and offer step-by-step support so you don’t have to face this process alone.

What Is Probate—And When Is It Required?


Probate is the legal process of settling a person’s estate after they pass away. It involves proving the validity of a will (if one exists), appointing an executor or administrator, inventorying assets, paying debts, and distributing what’s left to heirs or beneficiaries.

In Illinois, probate is typically required when:

  • The deceased owned real estate solely in their name.
  • Personal assets exceed $100,000 and are not jointly held or beneficiary-designated
  • There is no valid will in place.

We understand that every estate is different. Some are simple, others more complicated—especially when there are disputes, multiple properties, or family disagreements. Our job is to simplify the legal side, protect your responsibilities, and help close the estate efficiently.

Intestate Estates (No Will)

If your loved one passed away without a will, their estate is considered “intestate.” That means state law determines who inherits—and in what share. This can be confusing and emotional for surviving family members.

We guide you through the intestate process, helping to:

  • Identify legal heirs
  • Petition the court for estate administration
  • Distribute property according to Illinois law
  • Avoid unnecessary disputes

Even in the absence of a will, we work to ensure the process is as smooth and respectful as possible.

Dispute Resolution and Contested Wills

Sometimes, probate isn’t straightforward. Disagreements can arise over the validity of a will, the intentions of the deceased, or the actions of the executor. These situations require a steady legal hand and thoughtful conflict management.

Our firm assists in probate litigation involving:

  • Will contests
  • Breach of fiduciary duty
  • Undue influence claims
  • Improper asset distribution

With decades of courtroom experience, we know how to handle these disputes both aggressively and diplomatically, depending on the case.
