Frequently asked questions
How much can I sue for in Illinois if the letter is ignored?
$10,000 exclusive of interest and costs (Ill. Sup. Ct. R. 281). Money claims only; no separate small claims court — it is a simplified procedure inside the Circuit Court. The court is the Small claims in the Circuit Court (simplified procedure under Supreme Court Rules 281-289). Filing fee: Varies by county — set by county ordinance within Supreme Court fee schedules under 705 ILCS 105/27.1b; commonly ~$89 for the smallest claims up to ~$250-$330 for claims near $10,000 depending on county (Cook County runs higher). Check the circuit clerk's fee schedule for your county.. As of 2026; source: Ill. Sup. Ct. Rules 281-289; 705 ILCS 105/27.1b (fees).
Do I need a lawyer in Illinois small claims?
Attorneys are Allowed. Corporations appearing as plaintiff generally need counsel except as permitted by Rule 282(b).. That matters before you send the letter: where lawyers are barred, the person reading your letter knows they will be arguing it themselves, which is part of why demand letters get paid. Source: Ill. Sup. Ct. Rules 281-289; 705 ILCS 105/27.1b (fees) (as of 2026).
Can I demand more than $10,000?
Yes — a demand letter has no cap; only courts do. If you are owed more than $10,000, the letter is the same and the follow-through would be Illinois's regular civil docket instead of the Small claims in the Circuit Court (simplified procedure under Supreme Court Rules 281-289).
