Current as of: September 19, 2026 Probate & Estate Administration Illinois
⚖
In Illinois, Independent Administration allows executors to manage an estate with minimal court involvement, significantly reducing attorney fees. Supervised Administration is required for complex cases, minor heirs, or major family disputes, and requires a judge's approval for most estate actions.

Understanding Probate Types in Illinois

Navigating the legal system after a loss is challenging. Whether your case is handled in Chicago, Aurora, or Joliet, Illinois law provides two distinct tracks for probate: Independent Administration and Supervised Administration. Choosing the right path can dramatically impact how much time and money the estate spends. If you are unsure which route fits your family situation, you can easily find a local probate lawyer in our US Lawyers Directory to guide you.

Step-by-Step Process: Choosing Your Probate Path

Step 1: Identify if Supervised is Mandatory

In most standard situations, families prefer independent probate. However, Supervised Administration becomes legally mandatory if there are significant disputes among heirs, or if an heir is a minor or a person with a disability and their legal interests are not properly represented. In supervised cases, the court acts as a strict watchdog to prevent fraud or financial mismanagement.

Step 2: Filing for Independent Administration

If all heirs agree and there are no minors involved without representation, you can request the simpler process. You must file Form CCP 0315, Illinois, Circuit Court of Cook County, Petition for Probate of Will and for Letters Testamentary (if there is a will) or Form CCP 0302, Illinois, Circuit Court of Cook County, Petition for Letters of Administration (for intestate estates), selecting independent administration. This document is usually submitted to the Circuit Court of Cook County, Chicago, or your local county courthouse. The judge will then issue an order, governed by 755 ILCS 5/28-2, granting the executor the power to sell property and pay debts without asking the judge for permission every single time.

Step 3: Operating Under Supervised Administration

If you are in a supervised probate case, you must file a petition and obtain a formal court order for almost everything. Want to sell the deceased's car? You need a judge's signature. Ready to pay an accountant or issue inheritances? You need court approval. You will frequently interact with the DuPage County Circuit Court, Wheaton or whichever local court holds jurisdiction over the estate.

Step 4: Transitioning from Supervised to Independent

Sometimes, a probate case starts as supervised due to a dispute, but the conflict gets resolved. Under 755 ILCS 5/28-2(a), the executor or an interested party can petition the court to transition the estate to independent administration. This requires all interested persons to provide written consent. You would file a formal motion along with an individually prepared proposed order to finalize the switch and save costs moving forward.

How Much Does it Cost in Illinois?

The type of probate heavily dictates the final financial burden on the estate:

Court Filing FeesGenerally $250 - $400 depending on the county.Same initial fee, but extra motion filing fees apply over time.
Attorney CostsUsually $2,500 - $4,500 for standard, uncontested estates.Can easily exceed $7,000 due to frequent court appearances.

Because supervised probate requires significantly more paperwork, hearings, and court filings, lawyer fees add up quickly. We highly recommend finding an experienced attorney in our directory to get a precise local quote.

How Long Does the Process Take?

An Independent Administration in Illinois typically takes 7 to 12 months. This timeframe includes the mandatory 6-month statutory claims period allowing creditors to come forward. Conversely, Supervised Administration often drags on for 1 to 3 years, as the court's busy docket schedule dictates when you can move forward with asset sales and final distributions.

Frequently Asked Questions (FAQ)

Can an heir demand supervised administration?

Yes. Any interested party can object to independent administration, forcing the court to supervise the process to protect their financial share.

Does the will determine the type of probate?

Many modern wills explicitly request independent administration to save money, but the judge makes the final decision based on the heirs' circumstances and statutory rules.

Do I need a lawyer for independent probate?

While not strictly required by law, judges in many Illinois counties strongly encourage or practically require hiring a lawyer due to the complex procedural paperwork.

What is the first step to start either probate process?

You must file the original will, a death certificate, and a petition for probate in the specific county where the deceased lived.
