How to Sue a Friend or Family Member in Illinois Small Claims Court
Unpaid loans, bounced checks & personal money disputes
In Illinois, friend or family member disputes are handled in the Small Claims Court. You can sue for up to $10,000 without a lawyer — making small claims the fastest and most affordable way to resolve a friend or family member dispute. Suing a friend or family member is never easy — but when someone owes you money and won't pay, small claims court provides a formal, binding resolution. Whether it's an unpaid personal loan, a shared expense they bailed on, a bounced check, or money lent under a verbal agreement that was never honored, you have legal options. Most states allow personal loan claims up to $5,000–$25,000 in small claims court with no attorney required. Courts treat friend disputes no differently than commercial claims — if you can prove the debt existed and wasn't repaid, you can win. The biggest practical hurdle is enforcement after judgment: if the person has no wages to garnish or assets to collect, winning in court doesn't guarantee payment. That said, a judgment stays on their record and can be renewed, giving you real leverage.

Confirm your claim is within Illinois's $10,000 limit
Illinois's small claims limit is $10,000. If your damages are higher, you can reduce your claim to the limit or file in Illinois civil court. Use our Illinois Small Claims Limit guide for the full details.
Send a demand letter first
A formal demand letter — even sent by text — creates evidence the person knew they owed you money and chose not to pay. This eliminates the 'I forgot' defense in court. Courts in Illinois expect plaintiffs to have made a good-faith attempt to resolve the dispute. A demand letter also creates a paper trail and often prompts payment without any court filing.
Gather your evidence
Your case is only as strong as your evidence. Collect everything before filing — see the checklist below for exactly what you need for a friend or family member dispute.
Find the right Illinois courthouse
File at the Small Claims Court in the Illinois county where the friend or family member is located, does business, or where the dispute occurred. Before filing, look up the friend or family member's correct legal name and registered agent on the Illinois Secretary of State →. Using the wrong legal name is a common reason cases are dismissed.
Pay the filing fee ($56–$254)
Illinois small claims filing fees range from $56 to $254 depending on your claim amount. Use our Illinois Filing Fee Calculator to find the exact amount for your claim. Keep your file-stamped copy.
Serve the defendant properly
The friend or family member must be formally notified of the lawsuit. Illinois courts provide specific instructions — follow them exactly. Improper service is one of the most common reasons cases are dismissed.
Present your case at the hearing
Bring 3 organized copies of all evidence. Present your case in order: what happened, how much you lost, and why the friend or family member is responsible. Most Illinois small claims hearings last 15–30 minutes. Stay calm, stick to facts, and let the judge ask questions.
Sample Demand Letter: Friend or Family Member Dispute
Send this demand letter via certified mail before filing. Courts view prior good-faith attempts favorably, and many disputes settle at this stage. Replace the bracketed placeholders with your details.
I am writing to formally request repayment of $[AMOUNT] that I, [PLAINTIFF NAME], loaned to you, [DEFENDANT NAME], on [DATE] for [INCIDENT DESCRIPTION]. Despite the understanding between us that the loan would be repaid, and despite my prior informal requests, the full amount remains outstanding. I value our relationship and would prefer to resolve this matter without court involvement, which is why I am providing this written notice before taking further action. If I do not receive full repayment within 14 days of the date of this letter, I will have no choice but to file a claim against you in small claims court to recover the outstanding balance.
This is a template only — not legal advice. Consult an attorney if your situation is complex or the amount is significant.

Tips for Winning Your Friend or Family Member Case in Illinois
Consider whether the relationship is worth the legal battle — a judgment can permanently damage a friendship or cause family tension.
Even without a written contract, an oral loan agreement is enforceable in small claims if you have sufficient evidence (texts, transfers, witnesses).
Screenshot all relevant messages and payment records immediately after the dispute arises — people often delete them.
For bounced checks, many states have specific bad check statutes with penalties of 2–3x the check amount plus fees — stronger than a simple contract claim.
