DuPage Court System Overview
DuPage County is served by the 18th Judicial Circuit Court, which falls within Circuit District 3 of the Illinois unified court system. The 18th Judicial Circuit serves DuPage County exclusively — it is a single-county circuit. The Chief Judge of the circuit oversees court administration, judicial assignments, and local rule implementation. The circuit court is a court of general jurisdiction, meaning it handles all categories of cases — criminal, civil, family, probate, juvenile, and traffic — through specialized divisions rather than through separate district and magistrate courts. Associate judges hear many of the same case types as circuit judges, with assignments determined by the Chief Judge.

District Court Cases in DuPage
Illinois uses a unified circuit court system rather than separate district and magistrate courts. In the Felony Division of the 18th Judicial Circuit, circuit judges preside over serious criminal prosecutions — Class X felonies, Class 1 through Class 4 felonies, and first-degree murder cases. Felony cases typically begin when the DuPage County State's Attorney files charges following a grand jury indictment or a preliminary hearing. Cases are assigned to individual judges who manage them from arraignment through trial and sentencing. The court also hears post-conviction petitions, motions to vacate, and other post-judgment criminal matters. Civil cases involving larger dollar amounts and complex litigation — including contract disputes, personal injury, and real estate matters — are heard by circuit judges in the civil division.
Magistrate Court Cases in DuPage
Associate judges in the 18th Judicial Circuit handle many of the functions that magistrate judges perform in other states. The Misdemeanor and Traffic Division hears Class A, B, and C misdemeanors, traffic violations, DUI cases, and ordinance violations. Associate judges also preside over preliminary hearings in felony cases.
Small claims cases — civil disputes involving $10,000 or less under Illinois law — are heard in the civil division by associate judges. Civil cases above the small claims threshold but below more complex litigation levels are also assigned to associate judges. Because DuPage County has a high case volume, associate judges are typically assigned to specific divisions such as traffic, misdemeanor, or small claims to manage the caseload efficiently.
Family Law, Probate, and Juvenile Matters in DuPage
Family Law
The Domestic Relations Division handles divorce (dissolution of marriage), allocation of parental responsibilities (custody), child support, civil orders of protection, paternity, and termination of parental rights. The Illinois Supreme Court has approved standardized forms for divorce, child support, and maintenance that all circuit courts must accept. Certified copies of dissolution of marriage records can be obtained from the circuit clerk in the county where the dissolution was granted.
Probate
The Probate and Guardianship Division oversees decedent estates, guardianships of disabled adults and minors, conservatorships, and trust disputes. Guardianship applications and annual reporting requirements are managed through this division.
Juvenile
Juvenile delinquency cases, abuse and neglect proceedings, and truancy matters are heard in a separate juvenile courtroom. Juvenile court records are confidential under Illinois law and are not available through the public case lookup system. Contact the Circuit Clerk's office directly for questions about access to juvenile records.
How Cases Move Through the DuPage Court System
- Filing / Initiation: Criminal cases begin with a complaint or indictment filed by the State's Attorney. Civil cases start when a plaintiff files a complaint. Family and probate matters are initiated by petition.
- Case Assignment: The Circuit Clerk assigns each case a number and it is allocated to a judge within the appropriate division.
- Initial Hearing: In criminal cases, the defendant is arraigned and enters a plea. In civil cases, a scheduling conference sets deadlines for discovery and motions.
- Pre-Trial Phase: Parties exchange evidence through discovery, file motions, and may engage in plea negotiations (criminal) or settlement discussions (civil).
- Trial or Resolution: Cases proceed to a bench or jury trial, or are resolved by plea agreement, settlement, default judgment, or dismissal.
- Post-Judgment: Criminal cases may involve sentencing, probation, or appeals. Civil cases may involve enforcement of judgments or post-trial motions. Appeals go to the Second District Appellate Court.
