Illinois expungement and sealing: how 20 ILCS 2630/5.2 actually works with cannabis automatic expungement and Clean Slate

Illinois operates one of the more comprehensive criminal record relief frameworks in the country through the Criminal Identification Act, 20 ILCS 2630/5.2. The framework provides two distinct remedies: true expungement (complete record destruction) for qualifying non-conviction cases and certain cannabis convictions, and sealing (records hidden from public view but accessible to law enforcement) for most other convictions. The state also operates automatic cannabis expungement under the Cannabis Regulation and Tax Act of 2019, which has cleared hundreds of thousands of low-level cannabis records since taking effect in 2020.

The framework is undergoing significant change. The Illinois Clean Slate Act (HB 1836) takes effect June 30, 2026 with expanded petition-based eligibility including reduced waiting periods for misdemeanor convictions and certain probation completion cases. The automated sealing component of the Clean Slate Act doesn't take effect until January 1, 2029, with Illinois State Police developing the technological infrastructure for automated record processing during the interim period. Until 2029, all sealing and expungement requires individual petitions filed in circuit court.

The two-remedy framework matters substantively. Expungement under 20 ILCS 2630/5.2 destroys records, making them inaccessible even to law enforcement in most cases. Sealing preserves records but restricts access — the records remain available to law enforcement, prosecutors, courts, and employers in sensitive fields, but don't appear in standard public background checks. Most conviction cases qualify only for sealing, not expungement; expungement is generally limited to non-conviction cases (acquittals, dismissals, successful supervision completion) and specific cannabis convictions.

This is how the Illinois framework actually works under the post-Clean Slate Act amendments, the distinction between expungement and sealing, the cannabis-specific procedures, the petition-based procedure that remains the primary path until 2029, and the strategic considerations for Illinois residents seeking record relief.

Expungement vs. sealing in Illinois

The distinction between the two remedies is fundamental:

Expungement under 20 ILCS 2630/5.2. Complete destruction of records. The records are physically destroyed and made inaccessible to law enforcement, employers, and other third parties (with limited exceptions for specific government functions). The individual can legally deny the arrest or conviction occurred in nearly all contexts.

Sealing under the Criminal Identification Act. Records are preserved but restricted from public view. Sealed records remain accessible to:

• Law enforcement
• Prosecutors
• Courts
• Employers in sensitive fields (specifically defined categories including positions involving children, vulnerable adults, certain professional licensing)
• Future sentencing courts (sealed records can affect sentencing in subsequent cases)

The individual can typically answer "no" to questions about the conviction in employment applications and other non-government contexts, but the records continue to exist and can be accessed by authorized entities.

Most non-conviction cases qualify for expungement. Most conviction cases qualify only for sealing. This is the central organizing principle of the Illinois framework.

What qualifies for expungement

Expungement under 20 ILCS 2630/5.2 is available in specific situations:

Acquittals. Cases that resulted in a verdict of not guilty after trial. No waiting period.

Dismissals. Cases dismissed by the prosecutor or the court before final disposition (where no conviction resulted). No waiting period.

Cases where charges were never filed. Arrests that didn't result in formal charges. No waiting period.

Successful supervision completion. Illinois "supervision" is a form of probation that doesn't result in formal conviction. Successful completion of supervision allows expungement of the underlying records. No waiting period after successful completion.

Qualified probation completion. Several specific probation programs qualify for expungement after successful completion:

• 710/1410 drug probation (no waiting period)
• TASC (Treatment Alternatives for Safe Communities) probation
• Second Chance Probation
• Mental health court probation

Cannabis convictions for conduct now legal. Cannabis convictions for amounts that would now be legal under the Cannabis Regulation and Tax Act qualify for vacatur and expungement. Possession of up to 30 grams of cannabis is now legal in Illinois; convictions for such conduct can be expunged.

Successful drug probation completion. Specific provisions for drug-related diversion programs that result in case dismissal upon successful completion.

What doesn't qualify for expungement (with limited exceptions):

Conviction cases generally. Standard misdemeanor and felony convictions don't qualify for expungement; they typically qualify only for sealing.

DUI offenses. Convictions for driving under the influence and similar offenses are categorically excluded from both expungement and sealing.

Domestic battery. Domestic battery convictions are categorically excluded from both expungement and sealing.

Sex offenses against minors. Categorically excluded.

Animal cruelty. Categorically excluded from sealing under 20 ILCS 2630/5.2 (some exceptions exist).

Reckless driving. Generally excluded from both procedures.

The Cannabis Regulation and Tax Act automatic expungement

The Cannabis Regulation and Tax Act (CRTA), effective January 1, 2020, made significant cannabis-related conduct legal and created automatic record-clearing procedures:

Automatic expungement of minor cannabis arrests. Effective 180 days after July 29, 2016 (the effective date of Public Act 99-697, the precursor to CRTA), Illinois law enforcement agencies and circuit clerks are required to automatically expunge records related to civil violations of cannabis possession or paraphernalia (less than 10 grams in many circumstances).

Process. Records are automatically expunged on or before January 1 and July 1 of each year. No petition is required.

Eligibility for cannabis under 30 grams. Records of arrests, charges, and convictions for possession of cannabis amounts that would now be legal under CRTA can be cleared. For minor amounts (under 30 grams), the process is largely automatic.

Petition-based for larger amounts. Cannabis convictions involving 30+ grams up to 500 grams (and certain other cannabis-related offenses) qualify for petition-based vacatur and expungement under specific procedures established by CRTA.

Drug testing restriction. Notably, the framework specifies that courts cannot deny cannabis-related expungement petitions because the petitioner submitted a drug test within 30 days that indicated cannabis use. Cannabis use is now legal in Illinois; positive tests for cannabis don't undermine eligibility.

The CRTA framework has been one of the largest automatic record-clearing programs in U.S. history, clearing hundreds of thousands of cannabis records since taking effect. The framework illustrates what automatic record-clearing systems can accomplish when properly implemented.

What qualifies for sealing

Sealing under 20 ILCS 2630/5.2 is available for most convictions:

Misdemeanor convictions. Most misdemeanor convictions qualify for sealing after the waiting period.

Class 1, 2, 3, or 4 felony convictions. Most non-violent felony convictions in these categories qualify for sealing.

Specific exclusions. Convictions excluded from sealing eligibility:

• DUI offenses
• Domestic battery
• Class X felonies (the most serious felony class in Illinois)
• Homicide offenses (murder, manslaughter, reckless homicide)
• Robbery
• Residential burglary
• Vehicular hijacking
• Trafficking offenses
• Violent firearm offenses
• Sex offenses requiring registration

The waiting periods:

Pre-Clean Slate Act: 3 years from sentence completion for misdemeanors and Class 1-4 felonies.

Post-Clean Slate Act (effective June 30, 2026): 2 years for misdemeanors and ordinance violations (reduced from 3 years). Felony waiting periods remain at 3 years.

Qualified probation completion: 2 years from completion (reduced from 3 years under Clean Slate Act).

No new convictions during waiting period. The waiting period is "clean" — a new conviction during the wait resets eligibility. Minor traffic offenses don't reset eligibility under recent amendments.

Not currently under supervision or serving a sentence. The applicant must have completed all sentence components including probation and community supervision.

The Clean Slate Act timeline

The Illinois Clean Slate Act (HB 1836) takes effect on a phased schedule:

June 30, 2026. Petition-based provisions take effect:

• Reduced waiting periods for misdemeanor convictions (3 years → 2 years)
• Reduced waiting periods for qualified probation completion (3 years → 2 years)
• Various procedural improvements

January 1, 2029. Automated sealing provisions take effect:

• Illinois State Police identifies eligible records
• Records automatically sealed without requiring individual petitions
• Continued petition-based options for cases not covered by automatic procedures

The three-year gap between petition-based and automated implementation reflects the technical work needed to build the automated sealing infrastructure. Illinois State Police is developing the systems and procedures needed for automated identification and processing. Until 2029, all sealing requires individual petitions.

The Clean Slate Act provisions don't change the fundamental distinction between expungement and sealing or expand the categories of offenses eligible for relief. They expand procedural accessibility within the existing substantive framework.

The petition procedure

For Illinois residents pursuing expungement or sealing (the primary path until 2029):

Obtain criminal history record. Request an Illinois State Police criminal history transcript (approximately $16.50). The transcript shows the current status of all Illinois records and identifies any errors that need to be addressed.

Determine eligibility for each conviction or arrest. Review the specific case dispositions, the offense classifications, and the elapsed time against eligibility criteria. Identify which cases qualify for expungement, which qualify for sealing, and which are excluded.

Prepare petitions using approved forms. Standard petition forms are available through the Illinois Office of the State Appellate Defender and other resources. Use different forms for expungement and sealing — the procedures are distinct.

File in the correct court. For expungement, file in the county where the arrest occurred. For sealing, file in the county where the conviction occurred. Filing fees typically range from $120-$200 depending on the county. Fee waivers are available for indigent applicants.

Serve required parties. The petition must be served on:

• State's Attorney for the county
• Illinois State Police
• All arresting agencies involved
• Chief legal officer of the unit of local government effecting the arrest

60-day objection period. The State's Attorney has 60 days to file an objection. If no objection is filed, the petition may be granted without a hearing.

Hearing if objection filed. If the State's Attorney objects, the court schedules a hearing. The court gives at least 30 days notice. At the hearing, both sides present evidence. The State's Attorney must consult with Illinois State Police before the hearing on the appropriateness of the relief sought.

Court decision. The court issues a written order granting or denying the petition. Standards for granting include eligibility under the statute and consistency with the interests of justice.

Implementation. If granted, the order is forwarded to Illinois State Police, court clerks, and arresting agencies. The agencies have specific timeframes for updating their records to reflect the expungement or sealing.

Timeline. Typical processing from filing to implementation is 70-120 days for uncontested cases, longer for contested cases.

How Illinois compares to other state frameworks

The Illinois framework has notable features:

Compared to Michigan's Clean Slate (Public Act 193 of 2020 with automatic set-aside since April 11, 2023): Michigan's automatic framework is operational; Illinois's automated sealing doesn't take effect until 2029. Michigan's framework is currently broader in automatic relief.

Compared to Pennsylvania's Clean Slate: Pennsylvania has the first and most aggressive automatic sealing framework. Illinois's framework is conceptually similar but implementation is delayed until 2029.

Compared to New York's Clean Slate Act (effective November 16, 2024): New York's framework provides automatic sealing already. Illinois's framework lags but will eventually be comparable.

Compared to Ohio's framework (R.C. §2953.32 post-SB 288): Both states distinguish between expungement (destruction) and sealing. Ohio provides true expungement for more conviction categories than Illinois. Illinois provides expungement primarily for non-conviction cases.

Compared to Virginia's Clean Slate (effective July 1, 2026) and Washington vacating convictions: All three jurisdictions are moving toward broader record relief but through different procedural mechanisms. Virginia and Washington have automatic provisions taking effect in 2026; Illinois's automated provisions wait until 2029.

The broader national trend toward automatic record relief is detailed in our state-by-state expungement framework overview. Illinois's framework is currently among the more accessible petition-based systems and will become significantly more accessible when the 2029 automated provisions take effect.

Strategic considerations

For Illinois residents seeking expungement or sealing:

Identify the right remedy. Expungement provides stronger relief but is available primarily for non-conviction cases and certain cannabis convictions. Sealing is the typical remedy for conviction cases. The strategic decision depends on case-specific facts.

Take advantage of cannabis automatic expungement. For cannabis arrests and convictions covered by CRTA's automatic expungement, the records may already be cleared. Verify status through current Illinois State Police criminal history report.

Consider timing for misdemeanor sealing. The Clean Slate Act reduces misdemeanor sealing waiting periods from 3 years to 2 years effective June 30, 2026. Petitioners with cases approaching the 3-year point may benefit from waiting until after June 30, 2026 to file under the shorter waiting period.

Use approved petition forms. Illinois courts have standardized expungement and sealing petition forms. Using the right form for the specific remedy and case type is procedurally important.

Plan for the timeline. Processing from filing to implementation typically takes 70-120 days. Plan accordingly if specific deadlines (employment applications, professional licensing, etc.) are involved.

Use Illinois Legal Aid Online resources. Illinois Legal Aid Online offers free guided forms for expungement and sealing. The Chicago Lawyers' Committee and various county legal aid offices hold expungement clinics. These resources are particularly valuable for low-income petitioners who can't afford private counsel.

Engage attorney representation for contested or complex cases. Uncontested petitions are procedurally manageable for self-representation, particularly with available form resources. Contested petitions (where the State's Attorney objects) typically benefit from counsel. Illinois expungement attorneys typically charge $500-$2,500 depending on case complexity.

Wait for automated sealing if appropriate. For cases that will be eligible for automated sealing under the January 1, 2029 framework, waiting for automatic processing avoids petition costs. However, the wait is significant (2+ years) and during the wait the records remain visible.

Verify completion after orders. After court orders, verify that records have been properly updated. Request updated Illinois State Police criminal history reports to confirm expungement or sealing took effect. Errors can occur in implementation.

Don't assume federal effects. Illinois state-level relief doesn't directly affect federal background checks, federal firearms rights, or federal immigration consequences. The relief is state-level only.

Coordinate with employment and licensing implications. Some Illinois employment and licensing decisions consider sealed records. Understanding which entities have access to sealed records helps plan around the limited reach of sealing remedies.

For Illinois residents whose records affect their current opportunities, the framework provides meaningful paths to relief. The combination of expungement for non-conviction cases, sealing for most conviction cases, automatic procedures for cannabis records, and the developing Clean Slate Act framework provides multiple options depending on case specifics. The work for Illinois residents is in identifying which remedy applies to each case, gathering the necessary documentation, following through with the petition procedure (until automated sealing takes effect in 2029), and verifying that the relief was properly implemented. For cases that succeed, the framework provides substantial relief from the consequences of past records, though the relief is state-level only and may not affect all background check sources.
