California expungement under PC 1203.4: dismissal, sealing, and what the Clean Slate Act changed

California's record-relief framework is more complex than it looks. The state's primary statute, Penal Code §1203.4, is commonly called "expungement" but doesn't actually destroy or seal the underlying record. Instead, it provides dismissal of the conviction: the guilty plea is withdrawn, the case is dismissed in the interest of justice, and the petitioner is released from most "penalties and disabilities" resulting from the conviction. The record continues to exist; what changes is how it can be used.

That distinction mattered enormously for decades. A 1203.4 dismissal helped with private employment (private employers couldn't ask about dismissed convictions) but did nothing about background checks for housing, professional licensing, public employment, or government contracting. The Clean Slate Act (AB 1076, effective 2019, retroactive 2020) and its expansion through SB 731 and PC 1203.425 (effective January 1, 2023) fundamentally changed this. For convictions eligible for dismissal under 1203.4 and similar statutes, the court record is now automatically sealed without requiring petition. The combined relief is closer to what most people mean when they say "expungement," though the technical mechanics remain the dismissal-plus-sealing framework rather than true destruction of the record.

For someone navigating California's record-relief system in 2026, the framework asks three questions in sequence. Is your conviction eligible for 1203.4 dismissal? Has automatic relief already been applied under the Clean Slate framework? If not, does a petition-based remedy still apply? Understanding each question gets you to the correct path quickly, including the substantial number of cases where relief is already in place and the petitioner doesn't realize it.

What PC 1203.4 dismissal actually does

Penal Code §1203.4 applies to convictions where the defendant was placed on probation and successfully completed it. The statute provides a specific form of relief: the court permits withdrawal of the plea of guilty or no contest, enters a plea of not guilty, and dismisses the accusations or information. The defendant is then "released from all penalties and disabilities resulting from the offense" with several enumerated exceptions.

The relief is substantial in some contexts and limited in others.

What dismissal does provide:

Private employers in California cannot ask about or consider convictions that have been dismissed under 1203.4. California Labor Code §432.7 and the Fair Chance Act provide additional protections. A dismissed conviction generally cannot be the basis for adverse employment action by a private employer.

Most professional licensing boards in California cannot deny a license solely on the basis of a dismissed conviction under Business and Professions Code §480. The 480 protection applies to approximately 300 occupations regulated by the Department of Consumer Affairs.

The petitioner can answer "no" to standard questions about prior convictions on most private employment and housing applications, with limited exceptions noted below.

What dismissal does NOT provide:

The conviction record continues to exist in court files, law enforcement databases, and (until automatic sealing takes effect) background check databases. Public employers, law enforcement agencies, government contractors, and certain regulated employers can still see the record.

Firearm rights are not automatically restored. Convictions that triggered firearm prohibitions under state or federal law remain disqualifying regardless of 1203.4 dismissal. Separate restoration procedures apply for firearm rights.

The conviction can still be used against the petitioner in three specific contexts under §1203.4(a): a direct question contained in any questionnaire or application for public office, an application for licensure by any state or local agency, or contracting with the California State Lottery. The petitioner must disclose the conviction when directly asked in these specific contexts even if it has been dismissed.

Immigration consequences are generally unaffected by 1203.4 dismissal. The federal government does not recognize state expungement or dismissal for immigration purposes; a dismissed state conviction may still trigger deportation, inadmissibility, or naturalization consequences under federal immigration law.

The conviction can still be used as a prior in subsequent California criminal proceedings, including for sentencing enhancement, "strike" consequences under the Three Strikes Law, and similar uses.

Eligibility for 1203.4 dismissal

The traditional path to dismissal requires the petitioner to meet four conditions under §1203.4(a):

The petitioner was placed on probation for the offense. (Section §1203.4a provides similar relief for misdemeanor cases that didn't involve probation.)

The petitioner successfully completed probation, including all terms (fines, restitution, classes, community service). Probation violations don't automatically disqualify the petitioner; courts have discretion under §1203.4(a) to grant dismissal "in the interests of justice" even with prior violations.

The petitioner is not currently serving a sentence, on probation, or charged with another offense.

The petitioner did not serve time in state prison for the offense. Under California's Realignment legislation (Proposition 47, AB 109, and subsequent reforms), some convictions that would have resulted in state prison time before realignment are now treated as eligible under expanded provisions; the analysis depends on the specific offense and date of conviction.

Certain offenses are categorically excluded from 1203.4 dismissal, including serious felonies (violent offenses, sex offenses requiring lifetime registration under Penal Code §290, and several enumerated categories) and offenses with mandatory minimum sentences. The exclusions are listed in §1203.4(b) and incorporated into petition forms.

For convictions that don't qualify for 1203.4, separate provisions may apply: §1203.4a for non-probation misdemeanors, §1203.41 for certain felony convictions sentenced under §1170(h), §1203.42 for older felony convictions where the petitioner would have been sentenced to county jail under current law, and §1203.425 for the automatic relief framework.

The Clean Slate Act and automatic sealing

The transformation of California's record-relief system started with AB 1076 in 2019 and continued through SB 731 and the addition of Penal Code §1203.425 effective January 1, 2023. Together, these statutes added automatic sealing of court records to the existing dismissal framework.

The automatic relief operates as follows. The California Department of Justice identifies records eligible for relief based on the statutory criteria (type of offense, time elapsed, subsequent criminal history). For eligible records, the DOJ marks the record as sealed and provides notice to the relevant court. Beginning August 1, 2022, courts are directly prohibited from disclosing information about any conviction granted relief under §1203.4, §1203.4a, §1203.41, §1203.42, or §1203.425, except to the person whose conviction was granted relief or to criminal justice agencies.

For most eligible petitioners, this means the record is sealed without any action on their part. The conviction record continues to exist within criminal justice databases but is not accessible to private employers, landlords, professional licensing boards (with the narrow exceptions noted above), or other parties conducting background checks.

What automatic relief covers:

Most non-conviction records (arrests that didn't lead to charges or that resulted in dismissal or acquittal). Automatic sealing for these has been operational since the original AB 1076 implementation.

Misdemeanor convictions where the petitioner completed probation and has been conviction-free for the relevant waiting period (typically 4 years for the original AB 1076 framework, with SB 731 expansion to shorter periods for some offenses).

Many non-violent felony convictions where the petitioner completed sentence and has been conviction-free for the relevant waiting period (typically 4 years under SB 731 expansion for non-violent, non-sex-offense felonies).

What automatic relief does NOT cover:

Serious felonies, violent felonies, and sex offenses requiring §290 registration remain excluded from automatic relief. Petition-based dismissal under 1203.4 (where eligible) is the available path.

Convictions where the petitioner has subsequent criminal history that disqualifies them under the eligibility rules.

Convictions where the DOJ has determined the petitioner poses a continuing danger; AB 1076 includes a "dangerousness" review that can exclude individual cases from automatic relief.

If automatic relief was denied or didn't apply for some reason, the petitioner can still file a traditional petition for dismissal under 1203.4 or the applicable provision.

Petition-based dismissal: the procedure

For cases where automatic relief hasn't been applied or doesn't apply, the petition-based path under 1203.4 remains available. The procedural sequence:

Obtain criminal history records. Get a copy of your California Department of Justice record (a "Live Scan" request) and your court file from the convicting court. Confirm the accuracy of the records and identify the specific case to be addressed.

Prepare the petition. Most California superior courts provide Petition for Dismissal forms (often labeled CR-180 or a county-specific equivalent). The petition identifies the case, the offense, the date of conviction, the date of probation completion, and the basis for relief.

File the petition with the court that handled the original conviction. Filing fees range from $0 (waiver available for low-income petitioners) to $150 depending on the county. Some counties accept e-filing; others require in-person or mailed filing.

Serve the district attorney's office. The DA has the right to oppose the petition. Most petitions for routine 1203.4 dismissal are not opposed; petitions involving unpaid restitution, probation violations, or offenses that trigger discretionary considerations are more likely to receive opposition.

Attend the hearing if one is scheduled. Some counties handle uncontested 1203.4 petitions administratively without hearings; others require a brief court appearance. Hearings are generally short and decided based on the petition and any DA opposition.

Receive the dismissal order. If granted, the court issues an order dismissing the case under §1203.4. The order is sent to the California DOJ, which updates the record. Background check companies typically take 30 to 90 days to reflect the change.

The total timeline from petition filing to fully implemented dismissal is generally 2 to 6 months depending on the county and whether the petition is contested.

Special considerations for specific offenses

DUI convictions can be dismissed under 1203.4 if the petitioner completed probation, but the dismissal does not affect the DMV's separate record of the DUI for insurance and licensing purposes. The criminal record dismissal and the DMV record are managed under different statutes.

Drug possession convictions under Health & Safety Code §11350 and similar provisions are generally eligible for 1203.4 dismissal after probation completion. Many drug possession convictions are also eligible for reduction from felony to misdemeanor under Proposition 47, which can be a useful procedural step before pursuing dismissal.

Domestic violence convictions can be eligible for 1203.4 dismissal but federal firearms prohibitions under 18 U.S.C. §922(g)(9) generally continue regardless. Federal law treats state dismissals as not removing the underlying conviction for federal firearms purposes.

Marijuana convictions have a separate framework under Health & Safety Code §11361.8, which provides retroactive relief for many marijuana convictions that would no longer be crimes under Proposition 64 (recreational legalization). The marijuana-specific framework is faster and broader than 1203.4 for qualifying convictions.

Sex offenses requiring §290 registration are generally not eligible for 1203.4 dismissal. The Certificate of Rehabilitation under Penal Code §4852.03 is the available remedy for some §290 registrants, though it doesn't seal the registration record.

What dismissal under 1203.4 versus other states' systems

California's dismissal-plus-sealing framework is structurally different from other states' expungement systems in ways that matter for practical effect.

True expungement (record destruction) is rare in California. Most relief is dismissal that preserves the record while restricting access to it. Texas's expunction under Chapter 55A actually destroys the record; California's framework does not. We cover the broader state-by-state variation in our overview of state expungement frameworks.

Automatic relief is more developed in California than in most other states. Pennsylvania, Michigan, New Jersey, New York, and Virginia all have some automatic relief framework, but California's combined AB 1076 + SB 731 + §1203.425 system covers more offense categories with shorter waiting periods than most peer states.

The Business & Professions Code §480 protection for dismissed convictions in professional licensing is broader than equivalent provisions in many states. For petitioners pursuing licensed occupations in California, 1203.4 dismissal has more substantive value than equivalent relief might in other states.

Immigration consequences remain a serious limitation that California's dismissal framework doesn't address. Petitioners with non-citizen immigration status should work with both criminal defense and immigration counsel before pursuing 1203.4 dismissal because the strategic considerations differ from cases where immigration isn't a factor.

What to do if you're considering relief

Check whether automatic relief already applies. Request a current copy of your California DOJ record through a Live Scan service. Review how the conviction is reflected. If it's already marked as sealed or otherwise indicates relief has been applied, you may not need to file anything. The DOJ doesn't always notify individuals when automatic relief is applied.

Identify the specific statutory provision that applies to your case. The applicable section depends on the offense type, sentence imposed, and current circumstances. §1203.4 covers most probation-completed cases. §1203.4a covers non-probation misdemeanors. §1203.41 and §1203.42 cover specific felony situations. §1203.425 governs the automatic relief framework. §11361.8 covers marijuana convictions. The correct statutory provision determines the procedure.

For petition-based relief, consider whether you need attorney help. Routine 1203.4 petitions in uncontested cases are workable without counsel; California courts and resources like the Judicial Council forms make the process navigable. For contested cases (DA opposition, unpaid restitution issues, probation violation history), serious offenses with marginal eligibility, or cases with immigration consequences, attorney representation typically improves outcomes substantially.

For automatic relief that should have applied but didn't, the procedural path varies. Contact the California Department of Justice or your county's criminal records office to inquire about why automatic relief wasn't applied. Sometimes the issue is a technical disqualifier that can be addressed; sometimes a petition-based remedy is the available alternative.

The California record-relief system is genuinely more expansive than it was a decade ago, particularly with the automatic relief framework. For many people with eligible convictions, relief is either already in place or available with relatively modest effort. The work is in understanding which statutory provision applies and what procedural step (if any) is needed. For those with eligible convictions still affecting employment, housing, or licensing, the path to relief exists and the procedural cost is generally far lower than the benefit of clearing the record from public view.
