How Much Is the Fine for Missing Jury Duty in Cook County?

The fine for missing jury duty in Cook County is $5 to $100 under Section 15 of the Illinois Jury Act, paired with a contempt-of-court finding. That is the state penalty. If your summons came from the federal court in Chicago instead, the exposure is much higher: up to $1,000, up to three days in jail, community service, or a combination.¹²

The State Fine and the Contempt Finding

Under Section 15 of the Illinois Jury Act, a juror who was properly summoned and fails to appear without a reasonable excuse is treated as being in contempt of court. A judge can impose a fine of $5 to $100, payable to Cook County. The fine itself is modest. The contempt finding is the piece that matters, because it creates a court record and can escalate if you keep ignoring the court.¹

The statute also directs the court to issue an attachment order against a delinquent juror. In practice, that means you are compelled to appear before a judge and show good cause for the absence. The judge is allowed to accept your own sworn statement as evidence of the reason. For a first-time, unintentional miss, that hearing is usually where the matter ends. Repeated failures to appear can bring additional consequences, including community service or, in extreme cases, jail time.¹

Check Which Court Summoned You

Cook County residents can be called for either the Circuit Court of Cook County or the U.S. District Court for the Northern District of Illinois. The two systems have very different penalty structures, so look at the top of your summons before doing anything else.

A Circuit Court of Cook County summons falls under the state Jury Act, with the $5 to $100 fine range described above. A summons from the U.S. District Court falls under federal law, which authorizes a fine of up to $1,000, imprisonment for up to three days, community service, or any combination of those penalties.²

What Happens After a Missed Date

The court tracks who reported and who did not. If you are marked absent, expect a follow-up notice. That notice often takes the form of a show cause order, which requires you to appear before a judge and explain why you did not show up. Most missed-jury-duty cases end here: you appear, you give your explanation, and the judge decides whether the excuse was reasonable.

Ignoring the show cause order on top of the original summons is where things get serious. The court can issue a bench warrant. Warrants are not the first response, but judges do issue them when someone has been given multiple chances and still refuses to engage. A warrant can then surface during a routine traffic stop or a background check, well after you have forgotten about the summons.

Fix It Before Your Service Date

The simplest way to avoid any fine is to respond to the summons before the date on it. Cook County’s Jury Administration Office handles postponements, transfers to another courthouse, and requests for excusal. You can reach them at (312) 603-JURY (5879) or Jury.adm@cookcountyil.gov.³

Common grounds that support a postponement or excusal include:

Being 70 years old or older
A medical condition that makes service impractical, typically supported by a doctor’s note
Having already served on a jury within the past year
Being the primary caregiver for a young child or a person with a disability
Financial hardship severe enough that serving would create real difficulty
Full-time student status where coursework would be significantly disrupted

Have your documentation in hand before you call. A doctor’s note, class schedule, or letter from an employer explaining the hardship makes the request easier to grant. A postponement is generally simpler to obtain than a full excusal, so if the conflict is temporary, ask to reschedule.

Watch Out for Missed-Jury-Duty Scams

Scammers routinely call or email people, claim they missed jury duty, and demand immediate payment to cancel a supposed warrant. The fear of an arrest warrant is exactly what makes the pitch work. A few signs it is fake:

Demands for payment over the phone. No Cook County court collects fines by phone; legitimate fines are imposed by a judge after a hearing.
Insistence on gift cards, cryptocurrency, wire transfers, or payment apps, all of which are nearly impossible to reverse.
Requests for your Social Security number or date of birth. A real court will not call and ask for those details.

If you get one of these calls, hang up and contact the Jury Administration Office at (312) 603-JURY to check whether you actually have an outstanding summons.⁴
