You aced two interviews, then the background check landed on HR's desk and the phone stopped ringing. Or maybe it's the apartment you'll never get, the professional license held up “pending review,” or the volunteer form at your kid's school that asks the question you dread.

Even an old arrest — one that never led to a conviction — can follow you for years. The good news: Illinois law gives many people a real path to clear that record. The catch: the rules are technical, waiting periods vary, and Cook County's courts have their own procedures. Here's what you need to know in plain English.

Expungement vs. Sealing: They Are Not the Same Thing

The two most common forms of record relief in Illinois are expungement and sealing. People use the words interchangeably, but they do very different things — and only one is available for most convictions.

Both remedies are governed by Section 5.2 of the Criminal Identification Act, 20 ILCS 2630/5.2, which is the foundation of Illinois record-clearing law.

Expungement vs. Sealing at a Glance

Feature	Expungement	Sealing
What it does	Physically destroys or returns the records to the petitioner; the case is treated as if it never happened	Hides the records from most public view, but the file still exists
Who can still see it	Almost no one — limited law enforcement use in narrow situations	Law enforcement, courts, certain licensing agencies, and some employers (e.g., schools, healthcare with kids/elderly)
Who qualifies	Generally people who were not convicted — arrests with no charges, dismissals, acquittals, completed court supervision, or qualified probation	People with most misdemeanor convictions and many Class 3 and Class 4 felony convictions
Effect on background checks	Conviction/arrest typically disappears from private background reports	Standard private background checks should not return the sealed case
Can you legally say it never happened?	Yes, in most situations (with some narrow exceptions, like applying to be a police officer)	You generally do not have to disclose, but certain regulated employers may still see it

The short version: expungement is the gold standard, but most convictions can only be sealed. If your case ended in a conviction (other than reversed, vacated, or pardoned), expungement is almost certainly off the table — but sealing may still be available.

Who Qualifies in Cook County (and Who Does Not)

Illinois law applies the same way whether your case was in Chicago, Skokie, Rolling Meadows, or anywhere else in Cook County. But because Cook County handles more criminal cases than any other county in the state, local experience matters — the right courthouse, the right judge, and the State's Attorney's likely response are all things a Cook County attorney brings to the table.

You May Qualify for Expungement If

• You were arrested but never charged.
• Your case was dismissed, you were acquitted, or your conviction was reversed or vacated.
• You successfully completed court supervision (after the waiting period).
• You completed qualified probation — e.g., 720 ILCS 570/410 first-offender drug probation, TASC, or second-chance probation — after the waiting period.
• You received a pardon from the Governor that specifically authorizes expungement.

You May Qualify for Sealing If

• You have most misdemeanor convictions after the waiting period.
• You have Class 3 or Class 4 felony convictions not on the excluded list.
• You completed probation, conditional discharge, or a jail/prison sentence and have stayed out of trouble.

What Cannot Be Expunged or Sealed in Illinois

This is where many people get bad news. Under 20 ILCS 2630/5.2, the following are generally excluded:

• DUI convictions, including first-offense DUI — they stay on your record for life. (Narrower options may exist for DUI court supervision; talk to a lawyer.)
• Reckless driving (with limited exceptions for offenders under 25 with clean records).
• Domestic battery convictions.
• Violations of orders of protection.
• Sex offenses that require registration.
• Animal cruelty offenses.
• Most major and minor traffic offenses.

If you've been told a case “can't be expunged,” the next question is always: Can it be sealed? Sometimes the answer is yes. And if not, executive clemency from the Governor remains a long-shot but real option.

Illinois Waiting Periods: How Long Before You Can File?

This is the single most common question we hear, and it deserves a clear answer. The waiting period depends on the disposition of your case — not the offense level alone.

Illinois Expungement & Sealing Waiting Periods

Case Outcome	Type of Relief	Waiting Period
Arrest with no charges filed	Expungement	None — file immediately
Charges dismissed (nolle prossed, SOL, DWP)	Expungement	None — file immediately
Acquittal at trial	Expungement	None — file immediately
Conviction reversed or vacated	Expungement	None — file immediately
Court supervision — most offenses	Expungement	2 years after successful termination
Court supervision — certain enumerated offenses (e.g., specific Vehicle Code insurance/registration violations, battery, criminal sexual abuse)	Expungement	5 years after successful termination
Reckless driving (11-503(a)) — offender under 25, clean record	Expungement	When petitioner turns 25 (and meets other criteria)
Qualified probation (e.g., 720 ILCS 570/410 first-offender drug probation, TASC, second-chance probation)	Expungement	5 years after successful termination
Most eligible misdemeanor convictions	Sealing	3 years after completion of last sentence
Most eligible Class 3 or Class 4 felony convictions	Sealing	3 years after completion of last sentence
Cannabis: arrests for ≤30g, before June 25, 2019, no enhancements	Automatic expungement	No filing required in most cases (handled by Illinois State Police)

A few notes that trip people up:

• The waiting period for sealing runs from the end of the most recent sentence — including probation, parole, mandatory supervised release, or the date of your jail/prison discharge — not the date of conviction.
• A new conviction during the waiting period restarts the clock.
• The Illinois legislature has continued to expand record relief in recent years. Several “Clean Slate” reforms have been debated to shorten misdemeanor sealing waiting periods — talk to an attorney about whether any recent change affects your case.

The Cook County Process: Where and How You File

Under Illinois law, an expungement or sealing petition must be filed in the circuit court of the county where the case was prosecuted. If your case was in Cook County, that means:

• Felony cases — generally filed at the Leighton Criminal Court Building at 26th & California in Chicago (Criminal Division of the Circuit Court of Cook County).
• Misdemeanor cases — filed at the municipal district courthouse that handled the original case. Cook County is divided into six municipal districts:
  • District 1 – Daley Center (Chicago)
  • District 2 – Skokie
  • District 3 – Rolling Meadows
  • District 4 – Maywood
  • District 5 – Bridgeview
  • District 6 – Markham
• Traffic and DUI-related cases — usually filed in the same municipal district as the underlying case.

If your case was in Lake County (Waukegan, Vernon Hills, Mundelein), you'll file in the 19th Judicial Circuit at the Lake County Courthouse in Waukegan.

The petition is served on the State's Attorney's Office, the Illinois State Police, the arresting agency, and the chief legal officer of the municipality. Any of them can object within 60 days. If no one objects, the judge often grants the petition on the pleadings. If there is an objection, the court schedules a hearing. From filing to final order, expect 3 to 9 months in Cook County — sometimes longer if there's an objection or the Illinois State Police are slow to process the order.

Automatic Cannabis Expungement: What You Probably Don't Need to Do

When Illinois legalized adult-use cannabis through the Cannabis Regulation and Tax Act (410 ILCS 705/), the legislature paired legalization with one of the broadest automatic expungement programs in the country.

If you have a “minor cannabis offense” — generally, an arrest or conviction for possession (or non-aggravated manufacture/delivery) involving 30 grams or less, occurring before June 25, 2019, with no penalty enhancements and no associated violent offense — the Illinois State Police and the Governor's Office have been clearing these records automatically. You generally do not have to file anything.

The rollout has been phased and imperfect, though. If a minor cannabis case still appears on background checks, you can request your rap sheet from the Illinois State Police, then file a petition under 20 ILCS 2630/5.2 to clear anything the automatic process missed. For larger cannabis cases (over 30 grams, or post-2019), regular expungement and sealing rules apply.

Juvenile Records: Easier, but Not Always Automatic

Illinois treats juvenile records very differently. Many juvenile arrest and adjudication records are automatically expunged without any petition — particularly arrests that did not lead to a delinquency finding, and certain low-level adjudications after the person turns 18 or 21, depending on the offense. If a juvenile record hasn't been cleared, the petition process is generally faster and more forgiving than the adult version. Confirming the status of an old juvenile case is one of the easiest cleanup wins we see.

What Expungement and Sealing Actually Do for You

Clearing your record is not just paperwork. The practical effects are real:

• Employment. Expunged records will not appear on standard background checks; sealed records also will not appear on most private checks. Under the Illinois Human Rights Act, employers generally cannot ask about expunged or sealed records.
• Housing. Landlords routinely pull background reports. A cleared record removes one of the most common reasons for denial.
• Professional licensing. Nursing, real estate, insurance, cosmetology, and many other licensed fields consider criminal history. Cleared records carry far less weight in licensing decisions.
• Education and financial aid. Certain federal aid and graduate programs ask about criminal history. Expungement lets you answer “no” with confidence in most circumstances.
• Peace of mind. A clean record means moving forward without an old mistake hovering over every application.

The Limits You Should Know About

Expungement and sealing are powerful, but they are not magic:

• Federal background checks (FBI fingerprint checks, security clearances, immigration) may still surface records Illinois has expunged or sealed.
• Law enforcement and the courts can still see sealed records — and in narrow circumstances, even expunged records.
• Certain employers (schools, healthcare with vulnerable populations, law enforcement, the bar, the bench) have statutory access to sealed records.
• Immigration consequences are governed by federal law and are generally not eliminated by Illinois expungement. If you are not a U.S. citizen, consult both a criminal defense attorney and an immigration attorney before filing.

What It Costs

Unlike personal injury cases, expungement is not a contingency-fee matter. Our fees depend on what we're dealing with — how many cases, how many counties, what type of relief, and how complex the file is. Some petitions are straightforward; others take significant work. Court filing fees and Illinois State Police processing fees are also part of the picture, and a fee waiver is available for petitioners who cannot afford them. The best way to get a real answer on cost is a free consultation — we'll review your record and give you a straight number.

Frequently Asked Questions

Can I expunge a DUI in Illinois?

No. A DUI conviction in Illinois cannot be expunged or sealed under 20 ILCS 2630/5.2 — it stays on your driving and criminal record for life. The only narrow exceptions involve cases that did not end in conviction (for example, a DUI charge dismissed or reduced to a non-DUI offense). DUI court supervision is not technically a conviction, but the underlying record generally still cannot be expunged. Talk to a lawyer about your specific disposition.

How long does expungement take in Cook County?

Most Cook County expungement and sealing cases take 3 to 9 months from filing to the records actually being cleared by the Illinois State Police. The timeline depends on the courthouse, whether the State's Attorney objects, and how quickly the Illinois State Police process the order after the judge signs it.

Will an expungement show up on a background check?

Once the Illinois State Police process the order, an expunged case should not appear on standard private background checks. Sealed records also will not appear on most private checks, but they remain visible to law enforcement, courts, and certain regulated employers (schools, healthcare providers working with children or the elderly, etc.).

How much does it cost to expunge a record in Illinois?

Fees vary case-by-case. Attorney's fees depend on the complexity of your file — number of arrests or convictions, counties involved, and the type of relief requested. There are also court filing fees and Illinois State Police processing fees to factor in, and a fee waiver is available for petitioners who qualify based on income. The smartest move is a free consultation: we'll review your record and tell you exactly what your case looks like and what it costs. Call 847-520-4810.

What's the difference between expungement and sealing?

Expungement physically destroys or returns the records — for most purposes, the case is treated as if it never happened. Sealing hides the records from public view but the file still exists and remains accessible to law enforcement, courts, and certain employers. Most non-convictions qualify for expungement; most eligible convictions only qualify for sealing.

Can I expunge a felony in Illinois?

You generally cannot expunge a felony conviction in Illinois, but many Class 3 and Class 4 felony convictions can be sealed under 20 ILCS 2630/5.2 after a three-year waiting period from the end of your last sentence. Certain felonies — including most violent offenses, sex offenses, and felony DUI — are excluded from sealing entirely.

Do I need a lawyer to file for expungement in Illinois?

No, you are not legally required to hire a lawyer — the Office of the Illinois Courts publishes self-help forms, and Illinois Legal Aid Online has step-by-step resources. That said, eligibility rules under 20 ILCS 2630/5.2 are technical, the State's Attorney can object, and a denied petition can leave your record worse than before. For most clients, having an experienced attorney handle the petition is well worth it to get it right the first time.
