Illinois Court Filing Fees and Litigation Costs: What to Expect

Illinois court filing fees and litigation costs operate within a structured fee schedule governed by state statute and local circuit court rules. Fee amounts vary by case type, court level, and county — creating a multi-variable cost landscape that affects both represented and self-represented litigants. The Illinois Court System Structure page provides context on how the court hierarchy shapes where cases are filed and, consequently, what fees apply. This page maps the fee structure, identifies the principal cost categories litigants encounter, and defines the boundaries of the state-level framework.

Definition and Scope

Court filing fees in Illinois are statutory charges collected at the time a case is initiated or a document is filed with a circuit court. They are authorized under the Illinois Compiled Statutes, primarily through 705 ILCS 105 (Clerks of Courts Act), which sets baseline filing fees and authorizes circuit court clerks to collect them. Additional fee categories — such as automation fees, document storage fees, and State's Attorney fees — are layered on top of the base filing charge through separate statutory provisions, also codified in the ILCS.

Scope of this page: This reference covers Illinois state circuit court fees and litigation costs arising under Illinois law and Illinois Supreme Court Rules. It does not cover federal court filing fees in the Northern, Central, or Southern Districts of Illinois — those are set by 28 U.S.C. § 1914 and administered by the U.S. District Court Clerk's Office. Fees for Illinois administrative agency proceedings, arbitration costs, and attorney fee arrangements also fall outside the scope of this page. For the broader regulatory framework governing how Illinois courts operate, see Regulatory Context for the Illinois Legal System.

How It Works

Filing fees are assessed at initiation and at subsequent procedural stages. The circuit court clerk collects fees; in Cook County, the Clerk of the Circuit Court of Cook County administers one of the highest-volume fee schedules in the state.

Typical fee structure at filing:

1. Base filing fee — The foundational charge for opening a civil case. Under 705 ILCS 105/27.1a, civil filing fees in counties with populations over 1 million (Cook County) differ from those in smaller counties.
2. Automation and document storage surcharge — Added to nearly every filing under 705 ILCS 105/27.3a and 705 ILCS 105/27.3b.
3. Law Library fee — Collected under local ordinance in counties maintaining a law library.
4. Jury demand fee — A separate charge, typically ranging from $12.50 to $212.50 depending on county, required when a jury trial is demanded.
5. Service of process costs — Sheriff's service fees, which vary by county; Cook County Sheriff charges $60 per defendant for service within the county.
6. Appearance fees — Defendants filing an appearance in a civil matter pay a fee, generally equal to or lower than the plaintiff's initiation fee.
7. Motion fees — Certain contested motions carry individual filing charges.
8. Transcript and record fees — Court reporters charge per-page rates for transcripts; the Illinois Supreme Court's rate schedule provides baseline guidance.

Fee waivers are available under 735 ILCS 5/5-105 for indigent litigants who qualify. The waiver application is filed with the circuit court clerk and evaluated against income thresholds aligned with federal poverty guidelines published annually by the U.S. Department of Health and Human Services.

Common Scenarios

Small claims cases (disputes up to $10,000) carry reduced filing fees. Under Illinois Supreme Court Rule 281 and local circuit rules, small claims initiation fees are generally lower than standard civil filing fees — making Illinois Small Claims Court the lower-cost entry point for straightforward monetary disputes.

Dissolution of marriage (divorce) filings involve initiation fees that, in Cook County, have historically exceeded $300 for the petitioner alone, with additional surcharges for mandatory domestic relations automation funds. Respondents pay appearance fees separately.

Forcible entry and detainer (eviction) cases carry their own fee schedule, which is typically lower than general civil fees due to the expedited nature of the proceeding.

Post-judgment enforcement generates additional costs. Wage garnishment citations, citation to discover assets, and sheriff's levy fees each carry separate charges. For a detailed look at the post-judgment landscape, see Illinois Enforcement of Judgments.

Appeals to the Illinois Appellate Court require a filing fee under Illinois Supreme Court Rule 313. As of the fee schedule maintained by the Illinois Courts (illinoiscourts.gov), the appellate filing fee is $50 for civil matters, with additional clerk charges for record preparation.

Federal court contrast: Filing a new civil case in any of Illinois's three federal districts currently requires a $405 base filing fee under the federal fee schedule (28 U.S.C. § 1914(a)), which is generally higher than most Illinois circuit court initiation fees for comparable civil matters.

Decision Boundaries

The primary variable determining total filing cost is court level and county. Cook County's fee schedule diverges substantially from the 102 downstate counties, which follow a separate statutory tier under 705 ILCS 105/27.1.

Fee waiver eligibility represents a binary threshold: litigants who qualify under 735 ILCS 5/5-105 pay no filing fees; those who do not qualify pay the full schedule. Partial waivers are not a standard mechanism in Illinois circuit courts.

Case type classification determines which fee provisions apply. A domestic relations filing activates a different set of statutory surcharges than a general civil filing — even if the monetary amounts in dispute are identical. Misclassification at filing can result in supplemental fee demands from the clerk.

Illinois Pro Se Litigant Resources documents the practical tools available to unrepresented parties navigating this cost structure without attorney guidance. The Illinois Legal Aid and Access to Justice page covers organizations that provide fee-related assistance and represent clients whose fee waiver applications require advocacy.
