How to Subpoena Witnesses in Illinois Small Claims Court

When You Need a Subpoena

Your neighbor saw the contractor walk off the job. Your mechanic inspected the car and found the defect the plaintiff swears doesn't exist. You need them in court, and they've told you they'd rather not get involved. That's exactly what a subpoena is for — it's a court order that compels a witness to appear and testify under oath.

In Illinois small claims court, you can subpoena any person whose testimony is relevant to your case. A subpoena can also require a witness to bring documents or records (a subpoena duces tecum). The authority comes from Supreme Court Rule 237 and 735 ILCS 5/2-1101.

You don't need a lawyer to issue one. But you do need to follow the rules precisely, or the subpoena won't hold up.

How to Get and Serve a Subpoena

Start at the Circuit Court Clerk's office in the county where your case is filed. Ask for a blank subpoena form. In most counties you can also generate one through eFileIL if you're filing electronically.

Fill in the witness's full legal name, the case number, the date and time of the hearing, the courtroom or Zoom link (if your county conducts initial appearances remotely), and the specific documents you want them to bring, if any.

You may serve the subpoena personally or by certified or registered mail under Rule 237's requirements. For mail service, proof is prima facie if the witness or an authorized agent receives it at least seven days before the appearance date, with restricted delivery, an affidavit of mailing, and the witness fees and mileage enclosed. This seven-day period is a condition for that proof-of-service method, not a universal deadline for every subpoena. Personal service can be made by the county sheriff, a licensed private process server, or any person over 18 who is not a party to the case.

Here's the part many defendants miss: under 705 ILCS 35/4.3, a subpoena is legally unenforceable unless you tender the statutory witness fee at the time of service. That fee is $20 per day of attendance plus $0.20 per mile for round-trip travel from the witness's home to the courthouse. Hand the witness a check or money order along with the subpoena. If you skip this step, they can legally ignore it.

Timing and Practical Considerations

If you use the certified or registered mail method, allow at least seven days before the appearance date and follow Rule 237's delivery and affidavit requirements. Illinois law authorizes subpoenas for witnesses throughout the state under 735 ILCS 5/2-1101.

You may subpoena a witness who lives in another Illinois county. Rule 237(b)'s provision allowing the court to set terms for a nonresident's attendance concerns a party or a party's officer, director, or employee; it does not create a blanket county-of-residence limit for other witnesses.

Keep your witness list short. Judges in small claims hearings under Rule 286(b) conduct informal proceedings and will get impatient with redundant testimony. One strong witness who observed the key event carries more weight than three people repeating the same secondhand account.

What Happens if a Witness Ignores the Subpoena

A witness who has been properly served (with fees tendered) and fails to appear can be held in contempt of court. Before an order of body attachment for indirect civil contempt may issue, the witness must have an opportunity, after personal or abode service of a Rule 105 notice, to appear and show cause why they should not be held in contempt (735 ILCS 5/12-107.5).

In practice, judges rarely issue body attachments in small claims cases. What happens more often is the judge grants you a continuance to re-serve the witness or adjusts how much weight to give the testimony gap in the final decision.

Alternatives to a Subpoena

If your witness is willing to testify but can't attend on the hearing date, ask the court for a continuance to a date that works for everyone. File a written motion for continuance showing good cause and give notice to the opposing party.

For witnesses who simply don't want the inconvenience, sometimes a direct conversation explaining the stakes is enough. Most people cooperate once they understand they could be subpoenaed anyway.
