What To Do Immediately After an Illinois Arrest

The hours immediately following an arrest are critical. Illinois law gives you specific rights — but only if you invoke them. Here is exactly what to do:

  1. Stay calm and do not resist. Resisting a peace officer in Illinois is a separate charge (720 ILCS 5/31-1) that can make your situation significantly worse.
  2. Invoke your right to remain silent. Say clearly: “I am invoking my right to remain silent and I want a lawyer.” Do not answer questions beyond providing your name and ID.
  3. Do not consent to searches. Say: “I do not consent to any searches.” This preserves your Fourth Amendment rights even if officers proceed anyway.
  4. Remember everything you can. Write down officer names, badge numbers, what was said, and circumstances as soon as possible — your attorney will need this.
  5. Contact a criminal defense attorney before your first appearance. Since Illinois eliminated cash bail, a detention hearing can happen within 24–48 hours of arrest. Getting representation before that hearing protects your release under Illinois’s pretrial-fairness rules.

The Illinois Criminal Court Process: Step by Step

Understanding how Illinois courts process criminal cases helps you know what to expect and where your attorney can have the most impact. Both misdemeanors and felonies are handled in the Circuit Court of the county where the offense occurred.

1

Arrest & Charging

Police take you into custody. Prosecutors charge you by information, complaint, or (for felonies) grand jury indictment. What you are charged with can differ from the arrest offense, so early review by an attorney matters.

2

First Appearance & Detention Hearing

Since cash bail was abolished, a judge decides at a first appearance whether you are released on conditions. For eligible serious offenses the prosecutor may petition to deny pretrial release — your attorney argues at the detention hearing for release on the least restrictive conditions.

3

Preliminary Hearing or Grand Jury (Felonies)

For felonies, the State must show probable cause either at a preliminary hearing or through a grand jury indictment. Your attorney can challenge the sufficiency of the evidence, and many charges are reduced or dismissed at this stage.

4

Arraignment

You are formally advised of the charges and enter a plea. Your attorney ensures you understand the exposure before any plea is entered.

5

Discovery & Pre-Trial Motions

The prosecution must turn over its evidence under Illinois Supreme Court Rules 411–417. Your attorney can file motions to suppress evidence from an unlawful search, stop, or statement, and can move to dismiss defective charges.

6

Plea Negotiations & Diversion

Many first-time offenders qualify for diversion, drug court, or specialty courts. Where diversion does not apply, your attorney negotiates for reduced charges, probation, or lighter sentencing — how most Illinois cases resolve.

7

Trial & Sentencing

If no resolution is reached, your case goes to a bench or jury trial (a unanimous 12-person verdict is required for a conviction). If convicted, the judge imposes a sentence within the statutory class range, and your attorney presents mitigating factors to argue for the lowest sentence or probation where available.

Illinois Criminal Charge Levels & Sentencing

Illinois grades offenses under the Unified Code of Corrections (730 ILCS 5). Lower-level offenses are misdemeanors (Classes C, B, A); serious offenses are felonies graded Class 4 (least serious) up to Class X and first-degree murder.

LevelExamplesPunishment Range

Class B MisdemeanorCriminal trespass, harassmentUp to 6 months jail + fines up to $1,500

Illinois Ended Cash Bail: Why Your First Appearance Matters

On September 18, 2023, Illinois became the first state in the nation to fully abolish cash bail, under the Pretrial Fairness Act (part of the SAFE-T Act). Instead of posting money to secure release, most defendants are now released on non-monetary conditions while their case proceeds.

For certain serious or violent offenses, prosecutors may file a petition to deny pretrial release, and a judge decides at a detention hearing — usually within 24–48 hours of arrest. Because that hearing happens fast and can determine whether you remain free during your case, having an experienced Illinois defense attorney present from the outset is one of the most consequential decisions you can make. Your attorney can challenge the detention petition, argue for the least restrictive conditions, and keep you out of custody.

How To Choose an Illinois Criminal Defense Attorney

Not all defense attorneys are equal. When evaluating Illinois criminal defense lawyers, look for:

  • Illinois bar admission and criminal defense focus. Verify license status through the Attorney Registration & Disciplinary Commission (ARDC) attorney search.
  • Local court experience. An attorney who regularly appears in your county’s Circuit Court — whether Cook, DuPage, Lake, Will, Kane, or elsewhere — knows the judges, prosecutors, and procedures.
  • Trial experience. Ask specifically: “How many jury trials have you handled in the last two years?” You want someone willing and able to fight at trial if needed.
  • Experience with your specific charge. DUI, drug offenses, domestic battery, weapons, theft, and white-collar crimes each have distinct technical defenses.
  • Knowledge of diversion, sealing, and expungement. The right diversion program or a well-timed sealing petition can protect your record — ask whether you qualify.
  • Transparent fees. Get the full fee agreement in writing before signing anything.

⚠️ Red Flags to Avoid

  • Attorneys who guarantee a specific outcome before reviewing your case
  • Pressure to pay a large retainer before a full consultation
  • No written fee agreement
  • Attorneys who will not discuss trial experience or case results

Illinois Criminal Defense FAQ

How long does a criminal case take in Illinois?

Illinois misdemeanor cases often resolve in 2–6 months, while felonies routinely take 6–18 months and can run longer at trial. Illinois guarantees a statutory speedy trial: under 725 ILCS 5/103-5, a defendant held in custody must generally be tried within 120 days, and a defendant released on bond who demands trial must be tried within 160 days, excluding delays the defense causes. An experienced attorney can use these deadlines to pressure the prosecution.

What is the difference between a misdemeanor and a felony in Illinois?

Illinois grades misdemeanors as Class C (up to 30 days), Class B (up to 6 months), and Class A (up to 364 days in county jail). Felonies are graded Class 4 (1–3 years), Class 3 (2–5 years), Class 2 (3–7 years), Class 1 (4–15 years), Class X (6–30 years, non-probationable), plus first-degree murder (20–60 years or more). Because sentencing exposure rises sharply with each class, and some charges are enhanced by prior convictions, early legal representation is critical.

How does the Illinois SAFE-T Act affect bail and pretrial release?

Illinois abolished cash bail statewide on September 18, 2023 under the Pretrial Fairness Act (part of the SAFE-T Act), becoming the first state to eliminate money bond entirely. Instead of posting cash, most defendants are released on conditions. For certain serious or violent offenses, prosecutors may file a petition to deny pretrial release, and the judge decides at a detention hearing that usually happens within 24–48 hours of arrest. Having a defense attorney at that hearing is one of the most consequential decisions you can make.

Can a criminal record be expunged or sealed in Illinois?

Yes. Under 20 ILCS 2630/5.2, many Illinois arrests and some convictions can be expunged (destroyed) or sealed (hidden from most public view). Arrests that did not lead to conviction, and cases ending in acquittal or dismissal, are often eligible for expungement. Many misdemeanor and some felony convictions can be sealed after a waiting period (generally 3 years after completing your sentence). Certain offenses — such as DUI and most violent or sexual crimes — cannot be sealed. An Illinois criminal defense attorney can determine whether your record qualifies.

Should I talk to police before hiring an attorney in Illinois?

No. You have the right to remain silent and the right to counsel under the Fifth and Sixth Amendments and the Illinois Constitution. Clearly state “I am invoking my right to remain silent and I want a lawyer.” Questioning must stop once you unambiguously request an attorney. Anything you say beforehand can be used against you, so contact a criminal defense attorney before speaking with law enforcement.

How much does a criminal defense attorney cost in Illinois?

Illinois criminal defense fees vary by charge severity and county. Misdemeanor defense typically costs $1,500–$5,000. Felony defense ranges from $5,000–$25,000+, with complex cases and trials reaching $50,000–$150,000+. Many attorneys offer free initial consultations. If you cannot afford an attorney, the court must appoint counsel at no cost under the Sixth Amendment and Gideon v. Wainwright — in Illinois this is handled by the county Public Defender.

What are the penalties for a DUI in Illinois?

Under 625 ILCS 5/11-501, a first-offense DUI in Illinois is a Class A misdemeanor punishable by up to 364 days in jail, fines up to $2,500, and a minimum 1-year driver’s license suspension (statutory summary suspension). A third DUI is a Class 2 felony (aggravated DUI). Illinois also imposes an administrative statutory summary suspension separate from the criminal case, which you can challenge — but generally must do so within 90 days. Because DUI cannot be sealed or expunged in Illinois, fighting the charge matters.
