How Does Probation Work in California? Formal vs Informal Probation Explained
The short answer: probation in California is a sentence that lets you stay out of custody as long as you follow conditions set by the judge. Informal probation, also called summary probation or a conditional sentence, is supervised by the court itself and is the usual outcome in misdemeanor cases. Formal probation is supervised by a county probation officer and is the usual outcome in felony cases that do not result in prison. Since 2021, most misdemeanor probation is capped at one year and most felony probation at two years, but the conditions during that time, from search waivers to classes to stay-away orders, carry real consequences, and a violation can send you to jail for the full suspended sentence. This guide explains how probation is granted, what it requires, how it ends, and what happens when it goes wrong in Riverside, San Bernardino, Los Angeles, and Orange counties.
What Probation Is Under California Law
Probation is a suspended sentence with conditions. Under Penal Code section 1203, probation means the suspension of the imposition or execution of a sentence and the conditional release of the defendant into the community under the supervision of a probation officer. The same section defines a conditional sentence, commonly called informal or summary probation, as release without a probation officer, supervised by the court. In both forms, the judge keeps the power to impose jail or prison if you fail to comply. Our guide to how sentencing works in California explains where probation fits in the sentencing hearing.
Imposition suspended versus execution suspended. When a judge suspends imposition of sentence, no specific jail or prison term is chosen; if you violate, the judge can sentence you anywhere within the legal range. When a judge suspends execution of a specific sentence, that term has already been pronounced and will be imposed on a violation. Prosecutors in Riverside and San Bernardino counties often insist on an execution-suspended sentence, sometimes called a "hammer," as part of a plea bargain, and understanding which form you are accepting is essential before you plead.
Probation is a privilege, not a right. Penal Code section 1203, subdivision (e) lists categories of defendants who are presumptively ineligible for probation, including some who used a deadly weapon or who have two or more prior felony convictions, unless the court finds an unusual case under rule 4.413 of the California Rules of Court. For everyone else, the judge weighs the factors in rule 4.414 of the California Rules of Court, including the nature of the offense, the harm to the victim, prior record, remorse, and the likelihood of compliance. In felony cases, Penal Code section 1203, subdivision (b) requires a probation officer's report before sentencing.
Formal Probation vs Informal Probation
Informal probation is court-supervised. In a typical misdemeanor case at the Riverside Hall of Justice or the Rancho Cucamonga courthouse, the judge places the defendant on informal probation with conditions such as obeying all laws, paying fines, completing a class, and staying away from a person or place. There is no probation officer, no check-ins, and no drug testing unless the judge orders it. Compliance is proven by filing proof of completion with the clerk, and the next time the court hears about you should be when you file to terminate probation or to expunge the conviction.
Formal probation is officer-supervised. In a felony case, or a serious misdemeanor such as domestic violence or a second DUI, the judge may order formal probation. You report to a county probation officer, usually at an office in the county where you live, and the officer can require drug tests, home visits, employment verification, and permission before you travel out of the county or state. Riverside County and San Bernardino County both run formal probation through their probation departments, and the officer, not the judge, is your day-to-day contact. A High Desert resident on formal probation in Barstow or Victorville reports to the probation department's local office, and the court's and department's websites list current locations.
Formal probation is not parole or mandatory supervision. Parole and post-release community supervision under Penal Code section 3451 follow a prison sentence; mandatory supervision under Penal Code section 1170, subdivision (h) follows a split county jail sentence. Probation is different because no sentence has been served; the judge is giving you a chance to avoid it entirely. That difference matters for immigration, employment, and expungement.
How Long Probation Lasts in California After AB 1950
Misdemeanor probation is generally capped at one year. Penal Code section 1203a limits misdemeanor probation to one year, with exceptions for offenses that carry a specific probation length in their own statute. Before 2021, three years of misdemeanor probation was routine in Southern California courts; the one-year cap has reduced both the time on probation and the window for violations.
Felony probation is generally capped at two years. Penal Code section 1203.1 limits felony probation to two years, with exceptions for violent felonies listed in Penal Code section 667.5, for offenses with a specific probation length in their own statute, and for certain large-dollar theft and fraud offenses. Judges in Riverside and San Bernardino counties apply these limits at sentencing, and defendants sentenced to longer terms before the change have generally been able to seek modification.
Domestic violence and DUI are the major exceptions. Penal Code section 1203.097 requires a minimum of 36 months of probation for domestic violence offenses, and Vehicle Code section 23600 requires three to five years of probation for a DUI. Those statutory terms control over the general caps. Our guides to domestic violence charges at the Victorville courthouse and what happens after a DUI arrest explain those cases.
Common Probation Conditions in California
Conditions must relate to the crime or to future criminality. Under People v. Lent (1975) 15 Cal.3d 481, a probation condition is invalid if it has no relationship to the crime, involves conduct that is not itself criminal, and is not reasonably related to preventing future criminality. In In re Ricardo P. (2019) 7 Cal.5th 1113, the California Supreme Court struck down an electronics search condition that was out of proportion to the offense. These cases give the defense a basis to object at sentencing to conditions that go too far, and the objection must be made at sentencing or it is usually forfeited.
The search waiver is the condition with the most consequences. Nearly every felony probationer, and many misdemeanor probationers, must agree to a Fourth Amendment waiver allowing police to search their person, vehicle, and home without a warrant or probable cause. Officers in Fontana, Moreno Valley, and Hesperia run names during traffic stops specifically to find probationers with search terms. A search waiver is why a new arrest during probation so often produces a second case; our guide on when police can search your car explains how it changes the analysis.
Jail time, work release, and custody credits. A judge can impose county jail as a condition of probation, and many plea bargains include a short jail term served through a sheriff's work release program or electronic monitoring where available. Time already served in custody is credited under Penal Code section 2900.5, with conduct credits under Penal Code section 4019. Whether the jail term is served up front or hangs over your head as a suspended sentence is a negotiation point.
Financial conditions. Victim restitution under Penal Code section 1202.4 is mandatory and survives probation as a civil judgment. Fines and penalty assessments are set by the judge, who must consider ability to pay in many circumstances. Probation supervision fees were eliminated statewide in 2021, so a probation department that still demands a monthly supervision fee is applying a repealed rule.
Classes, treatment, and stay-away orders. Depending on the offense, probation commonly requires a DUI program, a 52-week batterer intervention program, anger management, a theft awareness class, drug or alcohol treatment, or community service. A criminal protective order under Penal Code section 136.2 on form CR-160 frequently continues through probation, and violating it is both a probation violation and a new crime under Penal Code section 273.6. Firearm conditions mirror the statutory bans in Penal Code section 29800 for felonies and Penal Code section 29805 for listed misdemeanors.
What Happens If You Violate Probation in California
A violation starts with a petition or a new arrest. Under Penal Code section 1203.2, the court can revoke probation when it has probable cause to believe you violated a condition, and a probation officer or prosecutor files a petition describing the violation. Common triggers are a new arrest, a missed class deadline, a failed drug test, a missed court date, or unpaid restitution. The judge often issues a bench warrant and sets no bail on a felony violation, which is why our guide to what happens if you miss court matters for probationers.
The hearing is easier for the prosecution than a trial. You are entitled to notice, a hearing, and a chance to present evidence under Morrissey v. Brewer (1972) 408 U.S. 471 and Gagnon v. Scarpelli (1973) 411 U.S. 778, but there is no jury, the standard of proof is a preponderance of the evidence rather than beyond a reasonable doubt, and the rules of evidence are relaxed. Our guide to probation violation hearings at the Victorville courthouse walks through the hearing in detail. If the violation is a new crime, the prosecutor often proceeds on the violation first because it is easier to prove.
The judge has a range of options. After finding a violation, the judge can reinstate probation on the same terms, reinstate with added jail or new conditions, or terminate probation and impose the sentence. For an execution-suspended sentence, that means the full term already pronounced. Judges at the San Bernardino Justice Center and the Riverside Hall of Justice tend to reinstate on a first technical violation and impose custody on repeated or new-crime violations, but the outcome depends heavily on preparation: proof of completed classes, employment, treatment enrollment, and payments made before the hearing changes the result.
Tolling and the probation clock. When probation is revoked, the running of the probation period is tolled under Penal Code section 1203.2 until the violation is resolved, so a violation filed near the end of probation does not simply expire. Getting a violation resolved quickly, or contesting it, keeps probation from stretching far beyond its original term.
How Probation Ends: Early Termination, Expungement, and Reduction
Probation can end early. Penal Code section 1203.3 allows the court to modify or terminate probation at any time in the interests of justice, and our guide to terminating probation early explains how judges in Riverside and San Bernardino counties evaluate those motions. Completion of all conditions, full restitution, employment, and a specific reason such as a job or housing requirement are the usual ingredients. Domestic violence and DUI probation are harder to shorten because of their statutory minimums.
Expungement follows successful probation. Once probation ends, Penal Code section 1203.4 allows you to withdraw your plea and have the case dismissed, using form CR-180, as explained in our expungement guide. Successful completion of probation makes the relief mandatory for most offenses; a probation violation does not bar it but moves the decision into the judge's discretion. Sealing an arrest that never led to a conviction is a separate process under Penal Code section 851.91.
Felony probation can lead to a misdemeanor. If the offense is a wobbler, Penal Code section 17, subdivision (b) lets the judge reduce the felony to a misdemeanor at sentencing or after probation, as our guide to reducing a felony to a misdemeanor explains. A reduction followed by expungement is the best available outcome for most felony probationers, and a lawyer should plan for it from the day the plea is entered.
Probation and Immigration, Employment, and Firearms
The 364-day rule. Penal Code section 18.5 caps misdemeanor sentences at 364 days so that a California misdemeanor does not trigger the federal immigration consequences that attach to a sentence of one year or more. A suspended sentence counts as a sentence for immigration purposes, so the length of the hammer in a plea bargain can matter more than the time actually served. Under Padilla v. Kentucky (2010) 559 U.S. 356 and Penal Code section 1016.3, counsel must evaluate those consequences before any plea.
Employment and licensing. A conviction with probation appears on background checks until expunged, and licensed professionals usually must report it. California's fair chance law restricts how private employers use conviction history, but it does not erase the conviction. Planning the plea with an eye toward a 17(b) reduction and prompt expungement limits the damage.
Firearms. A felony conviction brings a lifetime ban under Penal Code section 29800 whether or not probation was granted, and expungement does not restore the right. Listed misdemeanors, including domestic battery, bring the ten-year ban under Penal Code section 29805. Avoiding a qualifying conviction, through diversion or a plea to a non-listed offense, is the only way to keep firearm rights intact, which is why diversion under Penal Code section 1001.95 is often preferable to a probation sentence for eligible misdemeanors.
Frequently Asked Questions
What is the difference between formal and informal probation in California?
Supervision. Formal probation is supervised by a county probation officer with reporting, testing, and travel restrictions, and is typical for felonies. Informal probation, also called summary probation or a conditional sentence under Penal Code section 1203, is supervised by the court, has no probation officer, and is typical for misdemeanors. Both require obeying all laws and completing the conditions the judge sets.
How long is probation for a misdemeanor in California?
Usually one year or less. Penal Code section 1203a caps most misdemeanor probation at one year. Domestic violence offenses require 36 months under Penal Code section 1203.097, and DUI requires three to five years under Vehicle Code section 23600. Felony probation is generally capped at two years under Penal Code section 1203.1, with exceptions for violent felonies and certain other offenses.
Can I travel while on probation?
Usually within the county, and elsewhere with permission. Informal probation rarely restricts travel unless the judge says so. Formal probation generally requires the probation officer's permission to leave the county and always to leave the state, and a move to another state requires an interstate compact transfer. Traveling without permission is a technical violation that can be used against you later, so ask first and get the answer in writing.
What happens if I violate probation in California?
A hearing, and possibly the suspended sentence. Under Penal Code section 1203.2, the judge decides by a preponderance of the evidence whether you violated a condition and then chooses between reinstating probation, adding jail or conditions, or imposing the full sentence. Showing up with proof that you have fixed the problem, such as a completed class or a treatment enrollment, is the most effective way to be reinstated. A lawyer can also contest whether a violation occurred at all.
Can I end probation early in California?
Yes, if the court finds it is in the interests of justice. Penal Code section 1203.3 allows early termination, and judges generally expect completed conditions, paid restitution, a clean record during probation, and a concrete reason such as employment or housing. The motion is often paired with a request for a 17(b) reduction and expungement under Penal Code section 1203.4. Flat-fee representation is available for these post-conviction motions.
Does probation show up on a background check?
The conviction does, until it is expunged. Probation itself is a sentence, and the underlying conviction appears on criminal background checks while it stands. Once probation ends and the case is dismissed under Penal Code section 1203.4, most private employers may not consider it. Government licensing agencies and some employers can still see the dismissed conviction, so the plea itself is the place to limit the damage, as our guide on whether to take a plea deal explains.
