The Complete Legal Difference Between Expunging and Sealing a Criminal Record in Illinois

Current as of: September 16, 2026 Expungements & Record Sealing Illinois
📄
In Illinois, expunging a record means it is physically destroyed or returned to you, erasing it as if it never happened. Sealing a record means it is hidden from the general public and most employers, but law enforcement and courts can still see it. Both processes help you pass background checks for housing and employment.

Understanding the Criminal Identification Act

When you are trying to move forward with your life, an old criminal record can be a massive roadblock. In Illinois, you have two primary options to clean up your background: expungement and sealing. The rules for both are governed by the Criminal Identification Act, 20 ILCS 2630/5.2. While both options will stop a past mistake from showing up on a standard background check, they have entirely different legal definitions and outcomes. If you are unsure which option applies to you, you can easily find an experienced criminal defense lawyer in our US Lawyer Directory to help evaluate your case in cities like Chicago, Springfield, or Rockford.

Physical Destruction vs. Restricted Access

The core difference between these two processes comes down to what actually happens to the paperwork. Expungement results in the physical destruction of your arrest and court records. The Illinois State Police, Springfield will literally delete the files from their database, and the local court will destroy the physical documents or give them back to you. Legally, the event never happened. Sealing, on the other hand, means the records are put under restricted access. The files still exist in the government databases and courthouses, but a legal seal is placed on them so that everyday people cannot see them.

Who Can See Sealed vs. Expunged Records?

Because sealing and expunging treat the physical files differently, the people who have access to your history will change depending on which process you complete. Illinois courts, as shown in cases like People v. Thon, 319 Ill. App. 3d 855 (IL Appellate Court 2001), take the statutory limits and legal protection of sealed and expunged records very seriously.

Law Enforcement and Government Agencies

If your record is expunged, law enforcement agencies generally cannot see it. If you are pulled over for a traffic stop, the officer's computer will not show the expunged arrest. However, if your record is sealed, law enforcement, prosecutors, and the courts can still view your entire history. This is why sealing is often used for convictions that the state wants to keep an eye on, just in case you are arrested again.

Employers, Landlords, and the Public

For both expunged and sealed records, the general public, private employers, and landlords will not see your criminal history. When they run a standard commercial background check, your record will come back clean. However, there are exceptions for sealed records. If you apply for a job that requires fingerprinting or involves sensitive populations (like a hospital, school, or police department), those specific employers may still be able to see a sealed felony conviction.

Step-by-Step Guide: Which Do You Qualify For?

Figuring out whether you can expunge or seal your record depends entirely on how your case ended. Here is a step-by-step guide to help you determine your eligibility in Illinois.

Step 1: Obtain Your Criminal Record

You cannot guess your case outcomes. You must get a formal copy of your criminal history, often called a RAP sheet. You can request this from the Chicago Police Department, Chicago or your local arresting agency.

Step 2: Look for Convictions

Review your RAP sheet for the final disposition of each case. Did you receive a conviction? A conviction includes finding of guilt, prison time, or regular probation. If you were convicted of a misdemeanor or a felony, you generally cannot expunge it. Instead, you must look into sealing the record.

Step 3: Identify Dismissals and Acquittals

Did your case end in a dismissal, "Nolle Prosequi" (dropped charges), an acquittal (not guilty), or successfully completed Court Supervision? If you were not convicted, these arrests and charges are generally eligible for full expungement.

Step 4: Fill Out the Proper Forms

Once you know what you qualify for, you must fill out the official paperwork. The most common document is the Form EX-R 2903, Illinois, Circuit Court, Request to Expunge & Impound and/or Seal Criminal Records. You will file this with the Circuit Clerk in the county where you were arrested.

How Long Does the Process Take?

In Illinois, clearing your record is not a fast process. From the moment you file your petition at a local court, such as the Circuit Court of Cook County, Chicago or Circuit Court of DuPage County, Wheaton, the State's Attorney and the Illinois State Police have 60 days to object. If there is no objection, a judge will review your file. Generally, the entire process takes about 4 to 6 months in smaller counties, and up to 8 to 12 months in larger areas like Chicago.

Frequently Asked Questions (FAQ)

Do I have to disclose an expunged record on a job application?

No. Under Illinois law, you can legally answer "no" if an employer asks if you have ever been arrested or convicted of a crime that has been expunged.

Can all convictions be sealed in Illinois?

No. While most misdemeanors and many non-violent felonies can be sealed, certain crimes like domestic battery, DUI, and animal abuse cannot be sealed or expunged if they resulted in a conviction.

Can a sealed record be unsealed?

Yes, but typically only by a court order. If you commit a new crime, the court or prosecutors can view your sealed record to determine appropriate sentencing.

Do I need a lawyer to expunge my record?

While you are allowed to file the paperwork yourself, a simple mistake can result in a denial. Hiring a professional attorney ensures the correct statutes are cited and all waiting periods have been met.
