Illinois Criminal Defense Attorneys

At DearLegal, we connect you with experienced Illinois criminal defense attorneys who navigate the SAFE-T Act / Pretrial Fairness Act (eliminating cash bail since September 2023), recreational marijuana under the Cannabis Regulation and Tax Act, and Illinois’s broad expungement and sealing framework under 20 ILCS 2630/5.2. Whether your case is in Cook County, DuPage, Lake, Will, Kane, or anywhere across Illinois’s 102 counties, we’ll match you with the right attorney — at no cost to get started.

No. Politely decline and ask for an attorney. Chicago PD, ISP, county sheriffs, and suburban departments use trained interrogation techniques — and Illinois has had national high-profile false-confession cases. Illinois requires electronic recording of custodial interrogations for many felonies under 725 ILCS 5/103-2.1, but only after Miranda. Invoke your rights.

Yes. Illinois Class A misdemeanors carry up to 364 days in jail and $2,500 fines under 730 ILCS 5/5-4.5-55. Class B and C are shorter but still carry jail. Cook County and many other jurisdictions offer Deferred Prosecution and Drug School diversion. 410 Probation under 720 ILCS 570/410 is uniquely valuable for first-time drug offenses.

State cases go through Illinois Circuit Court (Cook, DuPage, etc.). Federal cases go to U.S. District Court for the Northern District (Chicago, Rockford), Central District (Springfield, Peoria, Urbana), or Southern District (East St. Louis, Benton) of Illinois under the U.S. Sentencing Guidelines. Federal cases in Chicago especially include drug trafficking (Mexican cartel sources), § 922(g) firearm prosecutions (Chicago violence focus), wire fraud, and public corruption.

Illinois plea agreements under Ill. Sup. Ct. R. 402 are negotiated between the State’s Attorney and defense. Pleas can include charge reductions, 410 Probation (first-time drug), 710 Probation (first-time felony cannabis), TASC probation, Deferred Prosecution, and recommended sentences. Cook County offers extensive specialty courts (drug, mental health, veterans).

Yes — Illinois has one of the most expansive sealing/expungement frameworks in the country. 20 ILCS 2630/5.2 allows sealing of most misdemeanors and Class 4-1 felonies after waiting periods (3 to 5 years). Many Class 2 felonies sealable. The Cannabis Regulation and Tax Act (410 ILCS 705/) provides automatic expungement of many low-level marijuana convictions. Class X felonies, DUI, and most sex/DV offenses are excluded.

Illinois handles juveniles under 18 in juvenile court under the Juvenile Court Act (705 ILCS 405/). Records are confidential and many are automatically expunged at 18 or 21 under 705 ILCS 405/5-915 (one of the broadest auto-expunge statutes in the country). Direct file by State’s Attorney is restricted; most adult transfers require judicial discretionary transfer hearings.

Illinois DUI under 625 ILCS 5/11-501 uses .08 BAC (.04 commercial, any amount under-21 / zero tolerance). Implied consent / Summary Suspension under 625 ILCS 5/11-501.1 — refusal or .08+ triggers 6- or 12-month administrative license suspension. Ignition interlock (BAIID) for all DUI convictions under 625 ILCS 5/6-205.2. Third DUI is a Class 2 felony.

Illinois grades felonies as Class X (mandatory 6-30 years, no probation), Class 1 (4-15 years), Class 2 (3-7 years), Class 3 (2-5 years), and Class 4 (1-3 years) under 730 ILCS 5/5-4.5. Murder is a separate offense with mandatory 20-60 years, life, or natural life depending on circumstances. The Truth-in-Sentencing Act (730 ILCS 5/3-6-3) requires 100% service for first-degree murder and 85% for many violent felonies. Illinois’s historic Pretrial Fairness Act (part of the SAFE-T Act, P.A. 101-652) took effect September 18, 2023 — eliminating cash bail entirely and requiring courts to base pretrial detention on dangerousness or flight risk. Illinois legalized recreational marijuana on January 1, 2020 under the Cannabis Regulation and Tax Act (410 ILCS 705/) — adults 21+ can possess up to 30g flower, 5g concentrate, 500mg THC infused. The Act also created automatic expungement for many prior marijuana arrests and convictions. Illinois sealing/expungement under 20 ILCS 2630/5.2 is broad — most felony classes (except Class X, certain DV/sex offenses) can be sealed after waiting periods. Clean Slate provisions (705 ILCS 405/5-915 for juveniles) automatically expunge many records.

Even a small misstep can hurt your case. Here’s what to avoid:

How Much Do Illinois Criminal Defense Attorneys Cost?

Flat Fee

Most matters are billed as a flat fee per petition or filing — fee depends on case complexity.

Criminal defense attorneys in Illinois work on hourly or flat-fee retainers — contingency fees are prohibited in criminal cases under Ill. R. Prof. Conduct 1.5(d) and ABA Model Rule 1.5(d). Misdemeanors and most felonies are flat-fee; complex cases (homicide, federal, multi-count) use hourly billing. The Cook County Public Defender’s Office and county/state PD offices represent indigent defendants — Cook County PD is one of the largest in the country.

What Can Your Illinois Criminal Defense Compensation Include?

Charge Dismissal

Outright dismissal through motion to quash (725 ILCS 5/114-1), motion to suppress (725 ILCS 5/114-12), speedy trial under 725 ILCS 5/103-5 (Illinois has aggressive 120-day in-custody, 160-day on-bond speedy trial rules), or SOL/SLA motion to dismiss.
