Expungement

Expungement is the California process for cleaning up your criminal record after you have completed your sentence. It does not erase the record entirely, but it changes the entry — the conviction is set aside and the case is dismissed, and you can legally answer “no” on most private employment applications about whether you have been convicted. For many people, it is the most meaningful step toward putting a past mistake behind them.

How Expungement Works in California

California’s main expungement statute is Penal Code § 1203.4, which applies to misdemeanors and felonies where the defendant successfully completed probation. Under § 1203.4, a person can petition the court to withdraw the guilty plea or verdict, enter a not-guilty plea, and have the case dismissed. The court must grant the petition in many cases as a matter of right; in others, it is discretionary, requiring a showing that relief serves the interests of justice.

People who served time in jail without probation can use Penal Code § 1203.4a (misdemeanors) or § 1203.42 (certain felonies). Felonies that are also wobblers can first be reduced to misdemeanors under Penal Code § 17(b), and then expunged — a powerful one-two punch that can substantially repair a record. People who never received a conviction at all (arrests with no charges, dismissals, or acquittals) can pursue arrest record sealing under Penal Code § 851.91, or factual innocence sealing under § 851.8.

California also offers the Clean Slate Act under Penal Code § 1203.425, which provides automatic relief for many qualifying convictions without requiring a petition. This affects most arrests not resulting in conviction and many older completed cases. However, automatic relief does not cover everything, and a manual petition is often still the best way to ensure full and accurate relief — especially for cases involving probation completion, complicated histories, or wobblers eligible for reduction.

There are limits. Some convictions are ineligible for expungement, including most sex offenses requiring registration under Penal Code § 290, certain serious traffic offenses, and any case where the person is currently on probation or charged with a new offense. Even successful expungement under § 1203.4 has carve-outs: it does not restore firearm rights, does not eliminate the obligation to disclose on government applications, and does not prevent the conviction from being used as a prior in a future criminal case. Knowing what expungement does — and what it does not do — is essential before relying on it.

Why Expungement Matters to Your Defense

Expungement is one of the most consequential post-conviction tools in California, because the practical impact of a criminal record is enormous. A clean record opens doors to employment, professional licenses, housing, and even certain government benefits. A skilled criminal defense attorney does not view the case as over when sentencing happens — they look ahead to the day relief becomes available and plan the path to it.

The work often combines several remedies. A felony might first be reduced to a misdemeanor under § 17(b), then expunged under § 1203.4, then accompanied by a Certificate of Rehabilitation under Penal Code § 4852.01. Each step matters and each builds on the others. Defense attorneys who specialize in this area know which combinations apply, what the realistic timing looks like, and how to present the petition persuasively to the court.

For non-citizens, expungement requires special care. Standard § 1203.4 relief does not eliminate a conviction for federal immigration purposes, and post-conviction relief may instead require a motion under Penal Code § 1473.7 to vacate the conviction based on prejudicial error affecting the ability to understand immigration consequences. Choosing the wrong remedy can be a costly mistake. Strong California criminal defense includes guidance on which path actually achieves what the client needs.

Expungement connects to the broader concepts of a criminal record, the wobbler doctrine that allows reduction under § 17(b), the option of arrest record sealing, and the post-conviction relief sometimes available through habeas corpus.
