Short answer: an attorney’s main value here is figuring out which relief you actually qualify for (expungement vs. sealing), preparing the petition correctly, and handling it if the state’s attorney objects — mistakes in this process commonly get petitions denied or delayed.
First, the key distinction: expungement vs. sealing

• Expungement physically destroys or returns the records — legally, it’s treated as if the arrest/case never happened. Generally only available when a case ended without a conviction (charges dismissed, acquittal, arrest with no charges filed, or successfully completed supervision in most cases).

• Sealing keeps the record but hides it from public view (most employers and landlords can’t see it), while it remains visible to law enforcement and certain licensing agencies. This is typically the option when there was a conviction.

What’s changed recently: Illinois enacted the Clean Slate Act (signed January 2026, automatic-sealing provisions effective mid-2026), which automates sealing for many eligible nonviolent records without requiring a petition, and shortens some waiting periods — for example, the waiting period for sealing most misdemeanor/ordinance convictions is dropping from three years to two. Whether your specific record falls under the automatic process or still needs a petition is exactly the kind of thing that’s easy to get wrong without help.

What’s generally NOT eligible, regardless of time passed:

• DUI convictions

• Domestic battery convictions

• Sex offenses requiring registration

• Violation of an order of protection

• Most violent felonies

• Minor traffic offenses

How a criminal defense attorney actually helps:

1. Determining eligibility. This isn’t always obvious — it depends on the exact disposition (dismissed vs. supervision vs. conviction), the specific charge, and how much time has passed since your sentence ended (not since arrest). An attorney pulls your full record and sorts out what qualifies for what.

2. Handling multiple or mixed records. If you have more than one arrest or case, some eligible and some not, the filing strategy matters — errors here can jeopardize otherwise-eligible records.

3. Preparing and filing the petition correctly. Petitions get denied for procedural mistakes — wrong court, missing records, incomplete forms — as often as for substantive eligibility problems.

4. Representing you if the State’s Attorney objects. Prosecutors can object to a sealing petition, which triggers a hearing where a judge weighs the request against public interest. Having an attorney argue that is very different from doing it alone.

5. Navigating the Clean Slate transition. Since automatic sealing is new, there’s real value in an attorney confirming whether your record was actually processed automatically or still needs action from you.

Bottom line: you can technically file some of these petitions yourself (forms are available free through the Clerk’s office or Illinois Legal Aid), but given how fact-specific eligibility is and how much a procedural misstep can cost you, most people benefit from having an attorney at least review the record before filing.
