Expungement and Record Sealing in U.S. Law

Expungement and record sealing are distinct legal mechanisms that limit public access to criminal history records, with direct consequences for employment eligibility, housing applications, professional licensing, and immigration status. Both processes are governed almost entirely by state statute, meaning eligibility rules, procedures, and outcomes differ sharply across all 50 jurisdictions. This page covers the legal definitions of each mechanism, how the processes work procedurally, the most common qualifying scenarios, and the factors that determine which remedy — if any — applies to a given record type.

Definition and scope

Expungement and record sealing are frequently conflated but carry legally distinct meanings under most state codes.

Expungement refers to the physical or legal destruction, erasure, or removal of a criminal record from court and law enforcement databases. In jurisdictions that permit true expungement, a granted petition results in the record being treated as though the underlying arrest, charge, or conviction never occurred. California Penal Code § 1203.4, for example, allows dismissal of certain convictions after probation completion, though the record itself may remain in court files accessible under limited circumstances — a hybrid outcome that illustrates how the term "expungement" is applied inconsistently by different state legislatures.

Record sealing does not destroy the record. Instead, it restricts access so that the record is invisible to standard background checks conducted by private employers or landlords, while remaining accessible to law enforcement agencies, courts, and — under most state frameworks — certain licensing boards. The sealed record continues to exist and can be unsealed by court order.

The distinction matters enormously in practice. Under civil vs. criminal law distinctions, a sealed conviction may still be treated as a prior offense in a subsequent criminal proceeding. A fully expunged record may not be.

Scope is also constrained by the nature of the underlying offense. Most state statutes exclude:

1. Violent felony convictions (e.g., murder, rape, aggravated assault)
2. Sex offenses requiring registry under statutes aligned with the federal Sex Offender Registration and Notification Act (SORNA), 34 U.S.C. § 20901 et seq.
3. Offenses involving minors as victims
4. DUI/DWI convictions in a significant number of states (including Pennsylvania and Illinois under their standard expungement statutes)

Federal criminal convictions are subject to a separate and far narrower framework. No general federal expungement statute exists for adult convictions; 18 U.S.C. § 3607 provides a limited expungement pathway only for first-offense simple possession of a controlled substance by individuals who were under 21 at the time of the offense (U.S. Code, 18 U.S.C. § 3607).

How it works

The procedural pathway for expungement or sealing follows a structured sequence that varies by state but commonly includes the following phases:

1. Eligibility determination — The petitioner or their attorney reviews the controlling state statute to confirm the offense type, disposition (dismissal, acquittal, conviction, deferred adjudication), and any mandatory waiting period have been satisfied.
2. Petition filing — A formal petition is filed in the court of conviction (or, for arrests without conviction, in the court with jurisdiction over the arrest). Filing fees vary; as of the most recent data published by the National Inventory of Collateral Consequences of Conviction (NICCC) — maintained by the American Bar Association — fees range from $0 in some jurisdictions to over $400 in others.
3. Notice to prosecutorial agencies — Most states require the petitioner to serve notice on the district attorney's office and the arresting law enforcement agency, both of which have the right to object.
4. Hearing (if contested or required) — Some jurisdictions mandate a hearing regardless of whether the state objects; others allow the court to grant the petition on the papers if unopposed.
5. Court order — If granted, the court issues an order directing all named agencies — typically the clerk of court, the state bureau of investigation, and local law enforcement — to expunge or seal the record within a specified timeframe.
6. Agency compliance — The FBI's Interstate Identification Index (III), maintained by the Criminal Justice Information Services (CJIS) Division, receives notification through state-level reporting; however, third-party background check vendors are not automatically updated and may retain outdated records unless separately notified under the Fair Credit Reporting Act (FCRA), 15 U.S.C. § 1681 et seq.

The FCRA, enforced by the Federal Trade Commission, imposes obligations on consumer reporting agencies to maintain accurate records, but the practical lag between a court order and database correction is a documented problem in criminal record accuracy literature.

Common scenarios

The following offense categories account for the largest share of expungement and sealing petitions filed nationally.

Arrests without conviction — Dismissals, nolle prosequi outcomes, and acquittals are the most broadly eligible category in nearly every state. The legal rationale, grounded in due process rights in the U.S., holds that an arrest record without a corresponding conviction creates a presumptive reputational harm without proof of wrongdoing.

First-time, low-level drug offenses — States including New York (under the Marijuana Regulation and Taxation Act, effective 2021) and Illinois have enacted automatic sealing or expungement for marijuana possession convictions below threshold quantities. Other states require petition-based proceedings.

Juvenile adjudications — Juvenile records occupy a distinct legal category under state juvenile codes. Most states seal juvenile records automatically at age 18 or upon petition shortly thereafter, though serious felony adjudications are typically excluded. The Office of Juvenile Justice and Delinquency Prevention (OJJDP) tracks state-by-state juvenile record confidentiality statutes.

Deferred adjudication and diversion completions — Defendants who successfully complete court-ordered diversion programs or deferred adjudication agreements often qualify for expungement as a built-in incentive of those programs, even where a standard conviction would not be eligible.

Misdemeanor convictions after waiting periods — Most states permit expungement or sealing of misdemeanor convictions after a waiting period (typically 3 to 5 years offense-free), subject to offense-type exclusions and limits on the number of prior convictions.

Decision boundaries

The threshold questions that determine whether expungement or sealing is available are highly fact-specific and turn on the following classification boundaries.

State vs. federal jurisdiction — Federal convictions are not expungeable under any general statute. State convictions are governed exclusively by state law, with no federal right to expungement recognized by the U.S. Supreme Court. The structure of the U.S. court system directly determines which body of law controls.

Conviction vs. non-conviction — Non-conviction records (dismissals, acquittals, no-bills from grand juries) are eligible in virtually all 50 states. Conviction records face a far narrower set of statutory conditions.

Offense severity classification:

Waiting periods — These range from immediate eligibility (for dismissals in many states) to 10 years post-sentence for felony convictions in more restrictive jurisdictions. The waiting period clock typically begins from the later of the conviction date or the completion of any sentence, including probation.

Subsequent criminal history — A new conviction during the waiting period resets or eliminates eligibility under most state statutes. This threshold is sometimes called a "clean period" requirement.

Automatic vs. petition-based relief — A growing number of states, including Pennsylvania (under the Clean Slate Act of 2018, 18 Pa. C.S. § 9122.2), Michigan, Utah, and Connecticut, have enacted automatic sealing statutes that operate without a petition for qualifying offenses. Petition-based systems require affirmative action by the individual. The distinction carries significant practical weight because sentencing guidelines and standards that result in probation-only sentences may render someone automatically eligible in an automatic-sealing jurisdiction years before they would otherwise seek relief.

The legal effect of a granted order also varies. Under most state statutes, a petitioner whose record is expunged may lawfully deny the existence of the arrest or conviction on private employment applications. However, exceptions apply for applications to law enforcement agencies, positions requiring state or federal security clearances, and licensing boards governed by statutes that require disclosure of expunged records. The rights of the accused in the U.S. framework shapes how courts interpret these disclosure carve-outs when constitutional challenges arise.
