Illinois Felony Classifications

Illinois classifies felonies into six categories, each carrying different sentencing ranges. Understanding your charge is the first step in building your defense:

Class Prison Sentence Extended Term Fine (Max)

Class X

6–30 years

30–60 years

$25,000

Class 1

4–15 years

15–30 years

$25,000

Class 2

3–7 years

7–14 years

$25,000

Class 3

2–5 years

5–10 years

$25,000

Class 4

1–3 years

3–6 years

$25,000

Murder

20–60 years

60–100 years / Life

$25,000

Note: Many felonies are probationable, meaning the court may impose probation instead of prison for certain offenses and first-time offenders. However, Class X felonies are generally non-probationable.

Collateral Consequences of a Felony Conviction

Beyond prison time and fines, a felony conviction in Illinois triggers serious collateral consequences:

  • Employment — Many employers refuse to hire convicted felons
  • Professional licenses — Nurses, teachers, real estate agents, and others may lose their licenses
  • Housing — Landlords can legally deny housing to felons
  • Firearm rights — Felons cannot possess firearms under Illinois and federal law
  • Voting — You cannot vote while incarcerated (rights restored upon release)
  • Immigration — Non-citizens face deportation, denial of naturalization, or inadmissibility
  • Student loans/financial aid — Drug convictions can disqualify you from federal aid
  • Child custody — Courts consider criminal history in custody determinations

Defense Strategies for Felony Cases

Every felony case is different, but effective defense strategies often include:

Challenging the Evidence

Was the evidence obtained legally? We examine whether police had probable cause for the arrest, whether searches were constitutional, and whether your Miranda rights were violated. Illegally obtained evidence can be suppressed.

Attacking the State's Witnesses

Eyewitness identification is notoriously unreliable. We investigate witness credibility, uncover inconsistencies, and expose biases or motives to lie.

Establishing Reasonable Doubt

The State must prove every element of the offense beyond a reasonable doubt. We identify weaknesses in their case and present evidence that creates doubt in the minds of judges and jurors.

Asserting Affirmative Defenses

Depending on the circumstances, defenses such as self-defense, defense of others, duress, entrapment, or necessity may apply.

Negotiating Reduced Charges

When the evidence is strong, we negotiate with prosecutors to reduce felony charges to misdemeanors, or to reduce the class of felony — significantly reducing potential sentences.

Pursuing Alternatives to Prison

For probationable offenses, we advocate for probation, drug treatment court, mental health court, or other alternatives to incarceration.
