Illinois State Guide · 2026
Illinois offers a relatively accessible framework for expunging and sealing criminal records compared to many other states - particularly through the Illinois Criminal Identification Act (20 ILCS 2630), which has been expanded several times through Smart Justice legislation. Expungement in Illinois applies primarily to non-conviction records (arrests, dismissals, acquittals, and completed supervision sentences), while sealing covers a broader range including certain conviction records after waiting periods. But as in every other state, obtaining legal relief in Illinois is only the beginning. The Cook County Clerk of Court portal, county-level public case searches, CourtListener, Justia, and data broker sites all hold independently indexed copies of your records that are entirely unaffected by expungement or sealing orders unless you take direct action on each platform.
