Cook County Pretrial Release, Detention and Bond Explained
Illinois ended cash bail for new cases when the Pretrial Fairness Act took effect on September 18, 2023. A family member usually cannot release a newly arrested person simply by paying a percentage of a newly set cash bond. The court instead decides whether to release the person, impose nonfinancial conditions or order pretrial detention after the required hearing.
The arresting agency begins processing and transport.
Identity, charges and jail classification are recorded.
A judge reviews release conditions or detention.
The person may be released, supervised or held by order.
The Clerk docket shows the upcoming court event.
The court may order appearance requirements, no-contact terms, electronic monitoring or another lawful condition.
The prosecution must use the applicable court process, and the judge determines whether detention is legally authorized.
The Cook County Bond Room still handles eligible monetary bonds, including qualifying legacy or other payable matters. Confirm with the Clerk before travelling.

Cook County Arrest Records FAQs
Where is the official Cook County inmate search?
Use the Cook County Sheriff’s Individual in Custody Locator at iic.ccsheriff.org. Search using the complete first and last name or the booking ID without a hyphen, then compare the birth date, booking date, charges and housing location.
How long after arrest does someone appear in the Cook County locator?
The Sheriff states that locator results are typically published four to six hours after the person is booked and processed into the jail. Transfer from the arresting police agency and unusual processing circumstances can take longer.
Does Cook County still use cash bail?
Illinois ended cash bail for new cases on September 18, 2023. A judge now determines release conditions or whether legally authorized pretrial detention is appropriate. The Cook County Bond Room still processes eligible payable monetary bonds, including qualifying older or other matters, so confirm the specific case with the Clerk.
How do I find a Cook County criminal court date?
Search the Clerk’s On-line Case Information using the case number or defendant name. You can also use the Cook County Automated Court Reminder System or call the Clerk. Online docket information is not the official court record and may update after a delay.
How do I find which Cook County Jail division holds someone?
Open the Sheriff’s custody result and read the housing-location field. The first characters identify the assigned division. You can also call the automated information line at 773-674-5245.
How do I apply to visit someone in Cook County Jail?
Create an official visitor account using a valid email address, complete the application with the same name shown on your identification, wait for approval and then schedule the correct in-person or family video visit for the person’s housing division.
What address should I use for Cook County Jail mail?
Address the letter with the individual’s full name and Cook County booking number, followed by 2700 S. California Ave., Chicago, IL 60608. Include a complete return address and review the prohibited-item rules before mailing enclosures.
How do I get a Cook County Public Defender after an arrest?
For someone still detained by police, call the Public Defender’s free 24-hour Arrest Response hotline at 844-817-4448. For an existing court case, use the Public Defender’s official location and attorney directory to contact the office assigned to that courthouse.
How do I request a Cook County arrest report?
Use the Cook County Sheriff’s FOIA portal for records maintained by the Sheriff. Chicago Police Department arrest reports must be requested from CPD because the Sheriff and CPD are separate agencies. FOIA is not the correct route for a complete Illinois criminal-history report.
Can a Cook County arrest record be expunged or sealed?
Some Illinois arrests and criminal cases may qualify for expungement or sealing, depending on the disposition and criminal history. Use the current Illinois Courts forms, obtain every case disposition and file in the Cook County district that handled the arrest or case.
