A DUI conviction from years ago can still follow you into job applications, housing searches, and background checks. California law offers a path to relief — but "expungement" doesn't mean the conviction disappears entirely, and understanding exactly what it does is the first step.
What Expungement Actually Does
Under California Penal Code § 1203.4[1], a qualifying defendant can petition the court to withdraw a guilty or no contest plea, enter a new not-guilty plea, and have the case dismissed. The result is a dismissal, not a deletion — your record will show the original conviction followed by a formal dismissal.
Filing in the Court That Originally Handled Your Case
If your DUI conviction came out of a Chino Hills arrest, the petition is generally filed in the same San Bernardino County Superior Court that handled the original case — typically the Rancho Cucamonga Justice Center[2]. Filing in the correct originating court matters; a petition filed in the wrong venue can face unnecessary delay.
Who Qualifies
Generally, you must have successfully completed probation for the DUI, or obtained an early termination of probation, and you can't be currently serving a sentence or facing new charges. Most uncontested petitions are resolved on the paperwork alone, without a hearing.
What Expungement Does Not Do
- It doesn't clear your DMV record. Your driving record is separate from your criminal record, and a DUI conviction typically remains visible there for 10 years.
- It can still count as a prior. If you're arrested for DUI again within that window, the expunged conviction can generally still be used to charge the new case as a second or subsequent offense.
- It doesn't restore firearm rights affected by the underlying conviction.
- Disclosure may still be required on applications for public office, most state professional licenses, or certain government positions.
Why It's Still Worth Doing
Under California Labor Code § 432.7[3], most private employers are prohibited from asking job applicants about, or considering, convictions that have been judicially dismissed. For the vast majority of job and housing applications, a dismissed DUI conviction generally no longer needs to be disclosed at all.

Frequently Asked Questions
Where do I file for expungement if I was convicted after a Chino Hills DUI arrest?
Generally in the same San Bernardino County Superior Court that handled your original case, typically the Rancho Cucamonga Justice Center.
Can I file while still on probation?
Not yet — you'll generally need to complete probation, or successfully petition for early termination, before the court will consider the petition.
Does expungement mean I never have to mention the DUI again?
For most private-sector job applications, yes, thanks to Labor Code 432.7 — but disclosure may still be required for certain government positions, professional licenses, or public office applications.
