How to Get Guardianship of an Elderly Parent in Illinois: A 2026 Guardianship Attorney Step-by-Step Guide

Families in Bolingbrook, IL, navigating guardianship for an aging parent need clear guidance from a qualified Guardianship Attorney to avoid costly delays. When a parent can no longer make safe decisions about health or finances, Illinois law provides a formal court process to appoint a legal guardian. Bolingbrook sits within Will County, so petitions are filed with the Will County Circuit Court in Joliet.

What Is Guardianship Under Illinois Law?

Illinois guardianship is a court-supervised legal status, not a private family arrangement. Under the Illinois Probate Act of 1975, a judge may appoint a guardian when an adult can no longer make or communicate responsible decisions about personal care or finances. Being elderly alone does not meet the legal standard. The court requires documented evidence of an inability to manage personal or financial affairs due to a condition such as dementia, physical incapacity, or mental illness.

There are two main types to consider.

▸ Guardian of the Person: Covers decisions about where your parent lives, what medical care they receive, and their daily well-being.

▸ Guardian of the Estate: Manages finances, assets, property, and bill payments on the parent's behalf.

Plenary vs. Limited Guardianship

A plenary guardian receives broad authority over all personal or financial decisions. A limited guardian is granted only the specific powers the court identifies. Illinois courts may prefer limited guardianship when a parent retains some decision-making capacity.

Step-by-Step: How to File for Guardianship in Will County

The process typically takes 60 to 90 days from filing to final court order when uncontested.

Step 1: Obtain a Physician's Report. Illinois requires a physician's report completed within three months before filing. The report must document your parent's condition and confirm they lack capacity to make their own decisions.

Step 2: Prepare and File the Petition. File a Petition for Appointment of Guardian for Person with a Disability in the Probate Division of the Will County Circuit Court. The petition must include your parent's personal information, their condition, why guardianship is needed, and who is proposed as guardian. Illinois now requires e-filing for civil cases.

Step 3: Serve Notice. Your parent must be served with a summons and a copy of the petition. Known relatives must also receive notice. Hearings are generally set within 30 days of filing.

Step 4: Guardian Ad Litem Review. Will County requires the court to appoint a guardian ad litem (GAL), who independently interviews your parent, investigates the need for guardianship, and reports findings to the judge.

Step 5: Attend the Hearing. The judge reviews all evidence and decides whether to appoint a guardian. If approved, you take an Oath and Bond before assuming legal duties.

Step 6: Ongoing Reporting. Guardians may have continuing duties including annual status reports and court approval for certain decisions.

What Documents Do You Need?

▸ Physician's report dated within three months of filing

▸ Signed Petition for Appointment of Guardian

▸ Summons for the Appointment of Guardian

▸ Notice of Motion to Relatives

▸ Oath and Bond of Representative
