Illinois Name Change Forms
Illinois doesn’t have statewide standardized form numbers — most counties use a generic petition format. Cook County and DuPage have local templates.
The main petition. Current name, requested name, reason for change, residency declaration, criminal-history affirmation.
Final court order signed by the judge after your hearing. Your legal proof of name change.
No statewide rule since March 1, 2025.
If you can’t afford the filing fee (varies; check your court). Courts grant indigency waivers based on financial hardship.
Step-by-Step Illinois Name Change Process
Same 4-step path in every county, with local variation in fees and forms.
Step 1: File Your Petition with the Circuit Court
File at the Circuit Court in the county where you reside. You must be an Illinois resident for the required period by the time of the hearing or order. Bring your completed petition, the filing fee or fee-waiver application, and any supporting documents.
The clerk reviews your paperwork, collects the fee, and assigns a case number. Filing fees vary by county; check your court.
Cook County and other large counties (DuPage, Lake, Will) may have longer backlogs. Check your county’s Circuit Court website before going.
Step 2: Check Whether Notice Is Required
Illinois repealed its statewide newspaper-publication rule (735 ILCS 5/21-103) effective March 1, 2025; whether any notice is required varies by county; check your court (official source).
Step 3: Attend Your Court Hearing
Brief proceeding. The judge verifies your identity, Illinois residency, and reasons.
Common questions the judge will ask:
- Why do you want to change your name?
- Are you changing your name to avoid debts or legal obligations?
- Do you understand this is a permanent legal change?
- Do you meet the Illinois residency requirement?
Be honest and direct. Valid reasons include personal preference, gender identity, religious or cultural reasons, family estrangement, or anglicizing your name. Most judges approve petitions when all legal requirements are met.
If anyone objects (rare), they appear at the hearing to state concerns. The judge hears both sides and decides.
Step 4: Get Your Certified Order
Once the judge approves, you receive a signed Order for Name Change. Request 4-5 certified copies from the clerk immediately.
