This guide explains what can happen if you miss jury duty and how courts usually handle it. You’ll also learn what to do right away to lower the chance of penalties.
Imagine you plan your day, then—through an accident, a mix-up, or bad timing—you do not appear when the jury summons says you must. For the court, that’s not just “a missed appointment.” It can delay court proceedings and affects other people’s trials. That is why there are clear steps and serious consequences for non-compliance.
How Cook County jury service is set up
In the Circuit Court of Cook County, the Office of Jury Administration helps run jury service. Its job includes mailing summonses, handling requests, answering juror questions, and paying jurors.
The “one day one trial” system
Cook County uses a streamlined system often called one day/one trial:
- You report on the date and time on your summons
- If you are not empaneled by the end of your first day, and you are not in a courtroom for jury selection, you are excused from further service
What time you report
You generally arrive promptly at the time listed on your summons—often 8:30 a.m., 9:00 a.m., or 9:30 a.m., depending on the location.
Where you report in Cook County
Here are the jury assembly room locations and key details:
| Jurisdiction location | Courthouse | Jury assembly room | Where |
|---|---|---|---|
| 1st Municipal District | Daley Center | Room 1700 | 17th floor |
| 2nd Municipal District | Skokie Courthouse | Room 111 | 1st floor |
| 3rd Municipal District | Rolling Meadows Courthouse | Room 220 | 2nd floor |
| 4th Municipal District | Maywood Courthouse | Room 59A | Lower Level (LL) |
| 5th Municipal District | Bridgeview Courthouse | Room 220 | 2nd floor |
| 6th Municipal District | Markham Courthouse | Room 219 | 2nd floor |
| Criminal Courthouse in Chicago | George N. Leighton Courthouse | Room 3A00 | 3rd floor |
If you do not show up at the location listed on your summons, the court can treat it as a failure to appear.
Dress, items, and technology you can bring
Dress code recommendations
Dress comfortably, but appropriately. The court says these are not permitted:
- shorts
- mini-skirts
- tank tops
- halters
If you arrive wearing these, you may be sent home to change.
Items you may bring
Because you may wait a long time, jurors are encouraged to bring:
- a book or other reading material
The court states you may NOT bring:
- cameras
- radios
Cell phones and electronic devices
Cook County’s device rules for jurors are different from some courthouse rules:
- You may bring cell phones and electronic devices into the courthouse
- You may use them in the jury assembly room
- You must turn them off when you are in a courtroom
- The judge will say whether you can use devices to take notes during trial
Wireless internet in the jury room
Yes. The court provides free wireless internet in the jury assembly rooms.
Nursing mother accommodations
A private lactation space is available. When you arrive:
- tell jury room personnel you need the lactation space
- if you later enter a courtroom, tell courtroom staff so they can make arrangements
Illinois law also states a mother may be excused from jury service upon request.
What if you miss a jury summons
Missing a jury summons can lead to a chain reaction. Courts generally follow an enforcement pattern: notice ? order ? judge review ? penalties.
Common enforcement path
| Step | What happens | Why it matters |
|---|---|---|
| 1 | Court sends a notice after you don’t appear | Signals the court has a problem to fix |
| 2 | The court may issue an order to appear and explain | You must respond, not ignore |
| 3 | If no good reason is shown, penalties can follow | Fines and court orders become possible |
| 4 | Willful non-compliance can become a criminal issue | This is when records and serious outcomes can happen |
Federal consequences if you fail to respond
For federal jury matters, the law spells out possible penalties.
Under 28 U.S.C. §1864(b), a person who fails to comply may face one or more of:
- a fine up to $1,000
- imprisonment up to three days
- being ordered to perform community service
It also states that a person who willfully misrepresents a material fact on a juror qualification form may be fined up to $1,000, imprisoned up to three days, ordered to perform community service, or a combination.
Missing jury duty can affect your record
Even if your first mistake seems small, contempt-related court actions can create a lasting legal problem.
A contempt finding can be serious because:
- it can lead to criminal-record style impacts depending on the situation
- it may affect future background checks
This is exactly why it’s important to respond quickly rather than hoping the issue disappears.
What to do right after you realize you missed it
1. Don’t wait
As soon as you learn you missed jury service, contact the correct court office as quickly as possible. Courts tend to respond more favorably when you show good faith.
2. Explain clearly
Be honest about what happened. If there was a mix-up, say so. If you moved, be ready to explain.
3. Fix your address
Courts stress the importance of providing an updated address for jury service. If your location details or mailing info are wrong, you may miss instructions without realizing it.
4. Keep proof
If you have any supporting documents (move proof, medical documentation, calendar issues), keep them ready.
Federal “Failure to Respond” and deadlines
If you miss the initial response requirement (federal rules mention a ten-day period), a “Failure to Respond” packet can be mailed.
Key points from federal instructions:
- A Failure to Respond packet includes paper copies of questionnaires
- You are urged to fill out questionnaires immediately
- Paper questionnaires must be returned within 5 days of receipt
If you do not have a computer
Federal courts provide options:
- use a public computer at a local library
- use a computer at the court location
- if those options aren’t available, request a paper copy by calling the court’s listed number
Also remember:
- if your address changed, provide the updated address
- return the paper forms within the deadline

Quick answers for the most common worries
“Is it ever just a warning?”
Sometimes you may get notices first. But you should not treat a summons as optional—courts can move to formal enforcement.
“Can I explain later?”
You should explain as soon as possible. Waiting makes it look less like a mistake and more like refusal.
“What if I never received the summons?”
If that’s true, act fast anyway: contact the court office and explain what happened. Proof can help, but timely communication is the key.
A practical checklist to avoid penalties
| Situation | Best action |
|---|---|
| You missed the date | Contact the court office right away and explain |
| Your address changed | Provide the updated address for jury service |
| You got a Failure to Respond packet | Fill out questionnaires immediately |
| No computer access | Use a library/court computer or request paper copies |
| You need an accommodation | Submit requests early when required |
Bottom line
Missing jury summons is taken seriously. The court expects attendance or a proper, timely response. If you realize you missed jury service, act quickly, communicate clearly, and correct details like your address. That approach gives you the best chance to avoid escalating consequences.
