This article covers the first procedure in an Illinois small claims case: getting it filed. It walks through confirming the claim fits the small claims track, picking the right county, completing the complaint and summons, paying the fee, and serving the defendant. Hearings, defenses, and collection are separate procedures with their own rules.
Confirm the claim fits the small claims track
Illinois defines a small claim by dollar amount and case type. Under Illinois Supreme Court Rule 281, a small claim is a civil action based on either tort or contract for money not in excess of $10,000, exclusive of interest and costs. The limit has been $10,000 since 2006, and the rule was last amended effective January 1, 2022, when tax-collection cases were removed from the definition.
Because interest and costs sit outside the cap, a claim for $9,800 plus accrued interest still qualifies. A claim above $10,000 does not become a small claim by rounding down: it is filed in the regular civil division of the same circuit court, under the full Code of Civil Procedure, unless the plaintiff permanently gives up the excess to stay within the limit.
Who files also matters. Under Rule 282(b), no corporation may appear as a claimant in a small claims proceeding unless represented by counsel. The same rule lets a corporation defend a small claims case through an officer, director, manager, department manager, or supervisor, but filing as plaintiff requires a lawyer. Individuals and sole proprietors file on their own behalf.
Choose the county: Illinois venue rules
Illinois small claims cases are heard in the circuit court, the state’s single trial court, and venue rules decide which county’s circuit court can take the case. Under 735 ILCS 5/2-101, an action must be commenced either in the county of residence of any defendant joined in good faith, or in the county in which the transaction or some part of it occurred. If all defendants live outside Illinois, the case may be filed in any county.
For a contract dispute, that usually means the defendant’s home county or the county where the work was done or the payment was due. For property damage or an injury, the county where it happened qualifies. When more than one county fits, the plaintiff picks. Filing in the wrong county gives the defendant grounds to challenge venue, which costs time even when the case survives the challenge.
Complete the Small Claims Complaint and summons
Rule 282(a) commences a small claims action by paying the filing fee and filing a short and simple complaint that states the plaintiff’s name, residence address, and telephone number; the defendant’s name and place of residence, business, or regular employment; and the nature and amount of the claim, with dates and other relevant information. If the claim is based on a written instrument, such as a contract, lease, or promissory note, a copy must be attached to the complaint, or the plaintiff must attach an affidavit explaining why the document is unavailable.
The Illinois Supreme Court publishes standardized statewide forms that every circuit court accepts, available on the approved forms page for the Small Claims Complaint. The suite includes the complaint, an Additional Defendants attachment, an Additional Reasons attachment, the Small Claims Summons, and a Letter to the Sheriff for arranging personal service.
Small Claims Complaint (Approved Statewide Form)
From Illinois Courts
URL verified June 2026
Identify both parties by legal name
Use full legal names. An individual sues in their own name. A defendant business is named by its legal name, with its place of business listed where the form asks for an address. A judgment entered against a misnamed defendant is harder to enforce later, because the name on the judgment has to match the name on the defendant’s accounts or wages.
State the amount and the reason, with dates
The complaint asks for the nature and amount of the claim. Specific beats general: “$4,200 for unpaid invoices dated March 3 and April 7, 2026” tells the court and the defendant exactly what the case is about. Vague descriptions invite continuances and disputes about what is actually claimed.
Attach the written instrument, if there is one
A claim based on a contract, lease, note, or other written document requires a copy attached to the complaint under Rule 282(a). If the document cannot be produced, an affidavit stating facts showing it is unavailable takes its place.
Prepare the summons
The summons is the court’s notice to the defendant. Its form is prescribed by Rule 283, and the statewide Small Claims Summons form from the approved forms page satisfies it. The clerk issues the summons when the complaint is filed.
705 ILCS 105/27.1b, civil filing fees are set within statutory schedules, and as of 2026 the caps run from $89 for the lowest schedule in counties under 3,000,000 people up to $366 for the highest schedule in counties over that population. The fee for a particular small claims case depends on the county and the amount claimed. Cook County, for example, publishes its small claims fee schedule through the Clerk of the Circuit Court’s Civil Division, where fees vary with the size of the claim.
A plaintiff who cannot afford the fee can apply to have it waived. 735 ILCS 5/5-105 authorizes the waiver of court fees, costs, and charges based on income, and the statewide Fee Waiver for Civil Cases form is the application the court reviews. Filing the application together with the complaint keeps the case moving while the court rules on the waiver.
## Serve the defendant
A defendant who has not been served is not required to respond, and a judgment entered without proper service is vulnerable to being set aside. Small claims has a service option most Illinois civil cases lack: certified mail handled by the clerk.
Under Rule 284, unless a circuit court rule provides otherwise, a plaintiff may request service by certified or registered mail in place of personal service for defendants within Illinois. The plaintiff pays the clerk a fee plus the cost of mailing and files a summons with an affidavit listing the defendant’s last known mailing address. The clerk then mails the summons and complaint, return receipt requested, with restricted delivery when the defendant is a natural person.
The traditional alternative is personal service by the sheriff of the county where the defendant lives or works. The statewide forms include a Letter to the Sheriff for requesting it, and sheriff’s fees vary by county. Certified mail costs less; personal service produces a sworn return from an officer, which leaves less room for a later dispute about whether the defendant was served.
## After the summons: the appearance date
The summons tells the defendant when and where to appear. Because Rule 284 requires mail service to be complete at least 21 days before that appearance day, the first court date typically lands a month or more after filing, with the exact gap depending on how quickly service succeeds and how the county schedules its small claims call.
What happens on the appearance date is governed by Rule 286, which covers the defendant’s appearance and the trial of the case. A defendant who was properly served and does not appear risks a default judgment, though the court still expects the plaintiff to establish the claim before entering one. Discovery in small claims is sharply limited compared to regular civil cases, which is part of why the track moves faster.
Between service and the appearance date, the plaintiff’s file is simple to keep in order: the stamped complaint, the issued summons, the proof of service, and the documents behind the claim. Cases settle at every stage, and a settlement before the appearance date can be reported to the court so the case is dismissed.
Frequently asked questions
Can I file an Illinois small claims case online?
Illinois operates a statewide e-filing system, eFileIL, that accepts filings from attorneys and self-represented litigants into any Illinois court. Some circuit clerks also accept paper filings from self-represented filers; practice varies by county, and the clerk’s office for the chosen county can confirm what it accepts.
Does a business need a lawyer to file a small claims case in Illinois?
A corporation does. Under Illinois Supreme Court Rule 282(b), no corporation may appear as a claimant in a small claims proceeding unless represented by counsel. The rule treats defense differently: a corporation sued in small claims may defend through an officer, director, manager, department manager, or supervisor when the amount claimed is within the small claims limit. Sole proprietors file in their own name without counsel.
How much does it cost to file?
The filing fee depends on the county and the size of the claim. The statutory caps in 705 ILCS 105/27.1b range from $89 to $366 as of 2026, with higher caps in counties over 3,000,000 people. Each circuit clerk publishes its own schedule. A plaintiff whose income qualifies can apply for a full or partial waiver using the statewide Fee Waiver for Civil Cases form.
What happens if the defendant ignores the summons? Can the court enter a default judgement?
A defendant who was properly served and fails to appear on the date in the summons can have a default judgment entered against them. The court generally requires the plaintiff to present enough proof to support the claim before entering judgment. Valid service is the hinge: if service was defective, a default judgment can later be set aside, which is one reason the proof-of-service paperwork matters as much as the complaint itself.
Can I sue someone who lives outside Illinois?
Sometimes. Rule 284’s certified-mail option applies to service within the state, so an out-of-state defendant requires a different approach, and the court must have personal jurisdiction over the defendant based on their connection to Illinois, such as a contract performed here or an injury caused here. When all defendants are nonresidents, 735 ILCS 5/2-101 allows filing in any county. Cases against defendants with no Illinois connection generally belong in the defendant’s home state.
