Understanding California Expungement Law: A Complete Guide to PC § 1203.4

California has one of the more widely used expungement frameworks in the United States, offering a meaningful path for people who have completed probation to clear their records under Penal Code § 1203.4. The process is sometimes referred to as a "dismissal" rather than a true erasure — an important distinction that shapes everything from employer background checks to professional licensing. Understanding exactly what PC § 1203.4 accomplishes, who qualifies, and how the Clean Slate Act of 2024 changed the landscape is essential before beginning this process.

What California's Expungement Law Actually Does

The term "expungement" in California can be misleading. Penal Code § 1203.4 does not erase or destroy the criminal record. Instead, it allows the court to withdraw a guilty or no-contest plea, enter a not-guilty plea in its place, and then dismiss the case. The result on your record is that the conviction shows as "dismissed" on Department of Justice (DOJ) records rather than as a conviction standing against you.

This distinction matters enormously. The conviction still appears in some databases and remains accessible to certain agencies and employers. What changes is how it is legally characterized and who can use it against you. For most private-sector employment purposes in California, however, this dismissal carries real and significant weight, thanks to companion protections in California Labor Code § 432.7.

Who Qualifies Under PC § 1203.4

Eligibility for a PC § 1203.4 dismissal hinges on several conditions. You generally qualify if all of the following are true:

You were granted and have successfully completed probation for a misdemeanor or felony offense. "Successfully completed" means you fulfilled all conditions of probation, including paying fines, completing community service, attending required programs, and avoiding new criminal violations.

You are not currently charged with a criminal offense, on probation for another offense, or serving a sentence for another crime at the time you petition.

You were not sentenced to state prison. This is a critical limitation. Individuals who served time in California state prison (as opposed to county jail under Realignment — AB 109) are generally not eligible for § 1203.4 relief, though there are separate statutes that may apply in limited circumstances.

Certain offenses are categorically ineligible regardless of probation completion. These include most offenses requiring sex offender registration under Penal Code § 290, violations of Vehicle Code § 42002.1, and certain serious offenses involving children. If you are required to register as a sex offender, § 1203.4 relief is generally not available to you under standard procedures.

The Clean Slate Act: AB 1076 and Automatic Expungement

One of the most significant reforms to California's expungement system in decades came with Assembly Bill 1076, signed into law and effective Jan. 1, 2024. Known as the Clean Slate Act, AB 1076 created a framework for the California Department of Justice to automatically petition for expungement on behalf of eligible individuals — without those individuals needing to file anything themselves.

The automatic process targets misdemeanor convictions where probation has been completed or discharged and a defined waiting period has passed. Eligible individuals receive the benefit of dismissal without navigating the court system, paying filing fees, or hiring an attorney.

However, there are important limitations to AB 1076's automatic process. Not every conviction qualifies for automatic processing. Felony convictions, offenses with state prison sentences, and any offense on the § 290 sex offender registration list are generally not covered by the automatic pathway. Individuals with those types of records still need to petition manually through the court where they were originally sentenced. Additionally, the DOJ rollout of automatic processing is ongoing, and not every eligible individual may have received their automatic dismissal yet. Checking your official DOJ record is the most reliable way to confirm whether the dismissal has been processed.

The Petition Process for Manual Expungements

For those who do not qualify for automatic processing under AB 1076 or whose automatic dismissal has not yet been processed, the manual petition route remains available. The process begins with filing a petition in the superior court that handled the original case. The court and county matter — each county processes petitions through its own clerk's office, and forms, fees, and local rules vary.

After filing, the court typically notifies the prosecutor's office, which has an opportunity to respond or object. A hearing may or may not be required depending on the county and the nature of the case. Many straightforward petitions are granted without a contested hearing, but the judge retains discretion in all cases.

Timeline from filing to granted dismissal varies considerably by county. Many counties in California process straightforward petitions in two to four months, though some high-volume courts take longer. Counties with heavier criminal court dockets — including some in the Los Angeles area — have historically had longer processing times.

What Expungement Does Not Do

Understanding the limits of PC § 1203.4 is as important as understanding what it accomplishes. There are several things expungement in California definitively does not do.

It does not restore firearm rights. Even after a § 1203.4 dismissal, Penal Code § 29800 may still prohibit firearm possession depending on the nature of the original offense. A felony conviction that has been dismissed under § 1203.4 may still trigger the federal prohibition on firearm possession under 18 U.S.C. § 922(g). Anyone concerned about firearm rights should consult an attorney before drawing conclusions from the dismissal alone.

It does not seal the record from law enforcement. Police, prosecutors, courts, and criminal justice agencies can still access and use the dismissed conviction. It remains part of your criminal history from their perspective.

It does not automatically restore professional licenses. Licensing boards in California operate under their own statutory frameworks. Some boards are required by law to consider the dismissal favorably; others retain broad discretion. Healthcare licensing boards (the Medical Board, Board of Registered Nursing, and others), real estate licensing, and law licensing boards each have their own rules about how dismissed convictions are treated. The dismissal is generally a factor in your favor, but it is not a guarantee that a revoked or denied license will be reinstated.

It does not eliminate the record from all federal databases. The FBI's Interstate Identification Index may still retain the underlying record. Federal agencies and positions requiring security clearances generally have access to the full criminal history regardless of state expungement or dismissal.

Employer Background Checks and Labor Code § 432.7

California Labor Code § 432.7 is where the practical employment benefit of § 1203.4 lives. This statute generally prohibits private employers from asking about, seeking, or using information about arrests that did not result in conviction and convictions that have been dismissed under § 1203.4. In most private-sector hiring situations, a California employer subject to § 432.7 cannot require you to disclose an expunged conviction.

The exceptions are significant, though. Government employers — including law enforcement agencies and positions in the criminal justice system — are generally exempt from § 432.7's restrictions. Jobs requiring a license, certificate, or permit from a state or local agency may also require disclosure. Certain healthcare positions, positions involving work with minors or vulnerable populations, and positions in the lottery or healthcare industries have specific disclosure requirements.

The practical takeaway is that for the vast majority of private-sector job applications in California, a § 1203.4 dismissal allows you to answer "no" or leave blank questions about prior convictions — with important exceptions carved out for the categories above. Misrepresenting your record in situations where disclosure is legally required is a serious risk, which is another reason consulting an attorney before making any disclosure decision is worth considering.

Common Record Types: Eligible vs. Ineligible

Most misdemeanor convictions where probation was granted and completed are eligible for § 1203.4 relief. This includes convictions for offenses like petty theft, simple assault, drug possession, DUI (with some nuances), and many other non-violent misdemeanors.

Felony convictions are eligible only if probation — not state prison — was the sentence. Some "wobbler" offenses (crimes that can be charged as either misdemeanor or felony) may also benefit from a reduction to misdemeanor status under PC § 17(b) before or alongside the § 1203.4 petition.

Offenses that involved a state prison sentence, crimes requiring sex offender registration under PC § 290, and offenses listed as ineligible under specific statutes (including certain crimes against children under PC § 288 and related provisions) cannot be dismissed under § 1203.4.

Taking the Next Step

If you have completed probation and are wondering whether your record qualifies for dismissal under California Penal Code § 1203.4, you may want to start by obtaining your official California DOJ criminal history report. This gives you an accurate picture of what is on your record and whether an automatic dismissal under AB 1076 may have already been processed. An attorney can review your eligibility for the manual petition process and advise on any complications — including prior convictions, parole issues, or licensing concerns — that may affect your outcome.
