Criminal Court Records in Mount Prospect

Mount Prospect is in Cook County. Every criminal case filed for the city goes through the Cook County Circuit Court. The Circuit Court handles the full range of criminal matters, including felonies, misdemeanors, traffic cases, and local ordinance violations. Cook County is the largest unified court system in the United States.

Cook County does not take part in re:SearchIL or the Judici database for criminal case records. Those systems serve most other Illinois counties but not Cook. To search a Mount Prospect criminal case, you have to go to a courthouse in person. No online access exists, and staff will not give out case details over the phone.

Mount Prospect is in the northwest part of Cook County. Cases from this area are often heard at the Rolling Meadows Courthouse at 2121 Euclid Ave., Rolling Meadows, IL 60008. Some matters may go through the main courthouse in Chicago. Before you make the trip, call the clerk at 312/603-5030 to confirm which location holds the file you need.

Cook County Circuit Court Clerk Contact

The Circuit Court Clerk for Cook County is Mariyana T. Spyropoulos. Her office handles all filings, record requests, and public access across the county's courthouse network.

• Main Office: 50 W. Washington St., Suite 1001, Chicago, IL 60602
• Phone: 312/603-5030
• Website: cookcountyclerkofcourt.org
• Rolling Meadows Courthouse: 2121 Euclid Ave., Rolling Meadows, IL 60008

Offices are open on weekdays. Standard hours are 8:30 a.m. to 4:30 p.m. Check with the clerk before going, as hours may change. Bring a valid photo ID. If you have the case number, bring it. If not, staff can search by name, though that may take longer if the name is common or if there are multiple filings under the same name.

Copies of records carry a per-page fee. Certified copies are available at a higher rate. Certified copies are typically needed for expungement petitions, legal proceedings, or other official purposes. Ask about accepted payment methods at the courthouse you plan to visit.

Using Public Access Terminals

Every Cook County courthouse has public access terminals in the clerk's office area. They are free to use. No appointment is needed. Anyone can walk in and search.

The terminals let you search by name or case number. Search results show the case index entry with charge type, court dates, and current status. Pulling up a specific case shows the full docket, which is a chronological list of every event and filing from the time the case opened to its close. You can see what motions were filed, when hearings were held, and what the outcome was.

Document images are not always viewable on terminals. For copies of specific documents, such as a charging sheet or a judgment, you request them from clerk staff. There is a fee per page. Certified copies cost more. Bring enough to cover a few pages and confirm payment options when you arrive.

If the name you are searching is common, having a date of birth or a year of filing helps narrow the results. Cook County processes a high volume of cases, so broad name searches can return many results. Plan extra time if you are not sure of the exact case details.

What Criminal Records Show

A criminal court file covers a single case. It is not a summary of all of someone's criminal activity. The file includes the charging document, all motions and orders filed, and the final disposition.

The charging document names the defendant, lists the charges with statute citations, and shows the date of filing. It may be a misdemeanor complaint, a felony information, or a grand jury indictment. The rest of the file tracks the case through court, including any bond orders, discovery motions, and pretrial rulings.

The disposition record shows how the case ended. A case can end by guilty plea, a not guilty verdict after trial, dismissal by the state, or dismissal by the court. If there was a sentence, the order shows what it was, whether jail time, probation, fines, community service, or conditional discharge.

Court supervision is another possible outcome. In supervision, no conviction is entered as long as the person meets certain conditions during a set period. The case still appears in the file but the record shows supervision rather than conviction. Understanding the distinction matters when you are reading a record.

Sealed and expunged records are not available to the public. Juvenile records are also closed. If a record falls under one of those categories, you may not be able to confirm it exists. The Circuit Court Clerk Act at 705 ILCS 105 defines the clerk's obligations around public access and record retention.

ISP Bureau of Identification

A court file covers one case. If you need a complete statewide criminal history for a person, the right source is the Illinois State Police Bureau of Identification. The ISP BOI maintains the state's official criminal history database and takes requests from individuals and authorized entities.

Address: 260 N. Chicago St., Joliet, IL 60432. Phone: 815/740-5160. You can submit a request online through the ISP portal or by mail. Fees apply. Turnaround time depends on the submission method and typically runs from a few days to a few weeks.

Individuals can request their own report to see what the state has on file. The report covers all Illinois counties. It includes arrests and dispositions reported to the state from every jurisdiction in Illinois. It is the most complete and reliable source for statewide criminal history information.

Authorized entities, such as schools, licensing boards, and law enforcement agencies, can also access the database under specific state rules. The rules are set out in the Criminal Identification Act at 20 ILCS 2635, which also governs expungement and record sealing in Illinois.

Statewide Court Search Tools

Cook County criminal records are not in any online database. But the re:SearchIL portal covers many other Illinois counties and is free since May 1, 2025. If you need to check cases from Lake County or other nearby counties, re:SearchIL is a good tool.
