Probation comes with a list of conditions, and life does not always make them easy to keep. A new job, a move, a missed class or a missed payment can lead to a violation, and a missed court date can lead to a warrant.
These situations are stressful, but they are often manageable when they are handled early and handled well. Marcus E. DeBose has defended San Diego clients since 2001. He takes the time to learn what happened and why, then explains it to the prosecutor and the judge. This page explains how probation works in California, what happens when a violation is alleged, how bench warrants and arrest warrants work, and how a San Diego probation violation attorney can help you get ahead of the problem instead of waiting for it to find you.
How probation works in California
Probation is a sentence served in the community instead of, or in addition to, time in custody. The court suspends some or all of the sentence and allows you to stay at home, at work and with your family, as long as you follow the conditions the judge sets. If those conditions are not followed, the court can revisit the sentence.
Formal and summary probation
California has two main kinds of probation. Formal probation, which is common in felony cases, is supervised by a probation officer. In San Diego County, that means the San Diego County Probation Department. Summary probation, also called informal probation, is common in misdemeanor cases. There is usually no probation officer; you answer to the court directly, often by providing proof that you completed classes or paid amounts owed.
| Formal probation | Summary (informal) probation | |
|---|---|---|
| Typical case | Felony cases, and some misdemeanors | Most misdemeanor cases |
| Supervision | A probation officer, with regular reporting | No probation officer in most cases; the court monitors compliance |
| General length since 2021 | Up to two years for most felonies, with exceptions | Up to one year for most misdemeanors, with exceptions such as DUI |
| Common conditions | Reporting, search terms, programs, restitution, obeying all laws | Classes, fines, restitution, obeying all laws |
Length of probation
Since 2021, California law has generally limited felony probation to two years and misdemeanor probation to one year. There are exceptions, including offenses whose own statutes set a specific probation term. DUI is the most familiar example: DUI probation is commonly three to five years.
Suspended sentences
When probation is granted, the judge either suspends the imposition of sentence, meaning no sentence has been chosen yet, or imposes a sentence and suspends its execution. The difference matters if probation is ever revoked, because it affects what sentence the court can order. Your attorney can tell you which applies to your case.
Search conditions
Many grants of formal probation, and some summary probation grants, include a search condition, often called a Fourth waiver. It allows officers to search you, your home or your car without a warrant within the limits the court set. Knowing whether you have one, and its exact scope, matters for anyone living with you and for how any later search is reviewed.
Mandatory supervision
Some people sentenced for a felony under Penal Code section 1170(h) serve part of the term in the community under mandatory supervision, with a probation officer. It is not the same as probation, but alleged violations of mandatory supervision are handled through a similar court process, and much of what is on this page applies.
Common probation violations
A violation can happen whenever you do not follow a term of your probation. Violations generally fall into two groups.
Technical violations
These involve the conditions of probation themselves, rather than a new offense. Common examples include:
- Missing a meeting with a probation officer, or failing to report a change of address
- Not finishing a required class or program on time
- Falling behind on fines or restitution
- A positive or missed drug or alcohol test
- Not completing community service hours
- Leaving the area without permission, where that is a condition
- Missing a progress report date in court
Program and class problems
Some of the most common violations involve classes and programs: a provider that closed, an enrollment that was never processed, a schedule that clashed with a new job, or a certificate that was never filed with the court. These problems are often fixable. Proof of enrollment, attendance records and a quick plan to finish can go a long way, especially when they are presented before the court has to ask.
New law violations
Almost every grant of probation includes a condition that you obey all laws. A new arrest or new charge can therefore lead to a violation as well as a new case. This is covered in its own section below.
Why the reason matters
In general, a court revokes probation for a violation that was willful. A missed appointment because you were in the hospital is not the same as ignoring a probation officer. When it comes to money, California law generally does not allow probation to be revoked for failing to pay restitution unless the court finds that the person had the ability to pay and willfully did not. The reasons behind a violation, documented properly, are often the most important part of the defense.
Fees that may no longer apply
In recent years California eliminated many administrative fees that were once charged to people on probation, and some older balances of those fees are no longer collectible. If you are worried about unpaid amounts, it is worth checking which of them are still owed before assuming you are in violation.
What happens after a violation is alleged
The process depends on the kind of probation and on what is alleged, but the general steps are similar.
How the court finds out
On formal probation, a probation officer who believes you violated a condition can report it to the court and ask for a hearing. On summary probation, the court often learns of a problem when proof of completion is not filed by a deadline, or when a new case is filed. A prosecutor can also bring an alleged violation to the court.
Summary revocation
Under Penal Code section 1203.2, the court can summarily revoke probation when it has reason to believe a violation occurred. That does not mean a final decision has been made. In general, it suspends probation while the matter is resolved and stops the probation clock, which can extend the time you remain on probation. If you are not already before the court, a bench warrant is often issued at the same time.
Arrest without a warrant
The same statute allows a probation officer or peace officer to arrest a person on probation without a warrant when there is probable cause to believe a violation occurred. That is one reason it is better to address a problem through the court than to wait.
Notice and a court date
Before the court makes a final decision, you are entitled to notice of what is alleged and an opportunity to respond. Many violations are resolved at a first or second court date, through an agreement or an explanation the court accepts. Others go to a formal hearing.
If you know you have fallen behind
If you realize you are going to miss a deadline, or already have, it is usually better to deal with it before the court or your probation officer raises it. Before you explain anything in writing or by phone, talk to an attorney. Statements you make about a violation can be used at a hearing, and how a problem is presented often shapes how it is received. An attorney can help you decide whether to ask the court for more time, file proof of what you have completed, or request a modification.
The probation violation hearing
A probation violation hearing is not a new trial. It is a hearing in front of a judge to decide whether a violation occurred and, if so, what should happen next. These hearings are sometimes called Vickers hearings, after the California case that set out the basic rights involved.

The standard of proof
There is no jury, and the prosecution generally only needs to prove the violation by a preponderance of the evidence, meaning that it was more likely than not. That is far lower than the "beyond a reasonable doubt" standard at trial. This lower standard is why preparation matters, and why a violation can be found even if a related new case is later dismissed.
A lower standard, but real rights. Penal Code section 1203.2 governs revocation. The prosecution's burden is lower than at trial, but you still have the right to be represented, to present evidence and to explain what happened.
Your rights at the hearing
- Written notice of the alleged violation
- Disclosure of the evidence against you
- The right to be represented by an attorney
- The right to be heard and to present witnesses and documents
- A limited right to confront and question adverse witnesses
- A decision by a neutral judge, with the reasons stated
Hearsay and evidence
Evidence rules are looser at a violation hearing than at a trial. Some hearsay can be admitted, particularly routine records such as program attendance reports. When the key evidence is a statement from someone who is not present to be questioned, however, the court has to weigh your right to confront that witness. Challenging the reliability of the evidence is often an important part of the hearing.
Admitting or contesting
Not every case should be contested. Sometimes the strongest approach is to admit a technical violation and focus on the explanation and the plan going forward, often as part of an agreement to reinstate probation. Other times the facts are disputed and a hearing is the right path. Marcus reviews the evidence and the likely outcomes with you before that decision is made.
Where the hearing takes place
A violation is generally heard by the court that granted probation. In San Diego County, that may be the Central Courthouse downtown, the East County Regional Center in El Cajon, the South County Regional Center in Chula Vista, or the North County Regional Center in Vista. For probation granted in southwest Riverside County, it is often the Southwest Justice Center in Murrieta. Knowing how a particular courthouse tends to handle these matters is part of preparing for them.
Possible outcomes
If the judge finds that a violation occurred, there is a range of possible results. The reasons behind the violation, and everything you have done right while on probation, can influence what the judge decides.
Reinstatement
The court can reinstate probation on the same terms. This is common when the violation is minor, the explanation is reasonable, and you have otherwise been doing well.
Modification
The court can reinstate probation with changes, such as additional classes or treatment, more community service, a new deadline, or a longer probation term within what the law allows. Some modifications can include custody time, which is one reason a strong presentation matters.
Revocation
The court can revoke probation and sentence you. If imposition of sentence was originally suspended, the judge can generally choose any sentence that was available when probation was first granted. If a sentence was imposed and its execution suspended, the court generally orders that same sentence carried out. Revocation is the outcome most people fear, and it is what a careful defense works to avoid.
What can help
- Proof that the missed requirement has since been completed, or is underway
- Records showing why the violation happened, such as medical or work records
- Evidence of what has gone well: steady work, completed programs, payments made
- A realistic plan to finish the remaining conditions
- Letters from employers, family or counselors
How long it takes
A straightforward technical violation can sometimes be resolved at the first court date, particularly when proof of completion is ready. A contested violation, or one tied to a new case, can take longer, because it may wait on the new case or require witnesses. While the matter is pending, probation is often suspended and its clock stopped, so delay is not always in your interest. Marcus can explain the likely timeline once he knows the details.
How a new arrest affects probation
A new arrest while you are on probation creates two separate problems: the new case and the probation case. They are connected, and handling them together is usually important.
Two cases, two standards
The new case must be proven beyond a reasonable doubt. The probation violation only needs to be proven by a preponderance of the evidence. Because of that difference, the court can find a probation violation based on the conduct behind a new arrest even if the new case is dismissed or never filed. An arrest by itself is not automatically a violation, but the conduct behind it can be.
Timing and strategy
The order in which the two matters are heard can matter. In some cases it makes sense to resolve the new case first; in others, the two are resolved together in a single agreement covering both. California courts have also placed limits on how testimony given at a probation hearing can be used against you in the related new case, but whether and how to testify still requires care.
Global resolutions
When both cases are in the same county, an agreement sometimes resolves the new charge and the probation matter at once, for example by reinstating probation with modified terms. Marcus looks at both cases together so that a decision in one does not create problems in the other. If the new charge is a DUI, see second and third DUI; for other new charges, see criminal defense.
When the new charge is minor
Even a low-level new charge, such as a citation for a misdemeanor, deserves attention when you are on probation. The outcome of the new case, whether a dismissal, diversion or a reduced charge, can affect how the probation court views it. Options such as misdemeanor diversion may still be worth exploring, though being on probation can be a factor the judge considers. See misdemeanor defense for those options.
Bench warrants and arrest warrants
A warrant is a court order authorizing law enforcement to take a person into custody. There are two main kinds, and they arise in different ways.
Bench warrants
A bench warrant is issued by a judge, usually when someone misses a court date or does not follow a court order. Common causes include a missed arraignment, a missed progress report on probation, or not filing proof of completion by a deadline. Many people do not realize a bench warrant exists until it surfaces.
Arrest warrants
An arrest warrant is issued when the police or prosecutors ask a judge for permission to arrest someone for a suspected crime. Some are issued after charges are filed; others, sometimes called Ramey warrants, can be issued before charges are filed when there is probable cause.
How warrants surface
Warrants are entered into law enforcement databases. Either kind can surface at a routine traffic stop, at the airport, at a border crossing, or during a background check for a job or a license. In general, warrants do not simply expire; they remain active until they are resolved.
Warrants and the border
Many San Diego residents cross the border with Mexico regularly for work or family. Law enforcement checks at ports of entry and checkpoints can reveal an outstanding warrant, sometimes years after a missed court date. If you travel frequently, it is worth confirming that you have no open warrants before a trip rather than finding out at the crossing.
Failure to appear as a separate charge
Missing court can also have consequences of its own. In some situations, willfully failing to appear can be charged as a separate offense. Addressing a missed date promptly, with a good explanation, can help avoid that.
Addressing a warrant with an attorney
Addressing a warrant with an attorney, before it surfaces on its own, may help. It does not guarantee any particular outcome, but it often gives you more control over when and how the matter is handled.
What an attorney can do
Depending on the case, an attorney may be able to find out what the warrant is for, file a request asking the court to recall it, and have the matter placed on calendar so that you can appear on a scheduled date rather than being picked up unexpectedly. In many misdemeanor matters, an attorney may be able to appear for you under Penal Code section 977. Felony matters generally require you to attend in person. Every case is different, and the court decides.
Why it can make a difference
Judges generally view a person who comes to court voluntarily, with an attorney and an explanation, differently from a person who is brought in after an arrest. Coming in on your own terms also lets you arrange work and family obligations, bring documents that explain what happened, and show what you have done since.
What to bring
- Any paperwork from the original case, including the sentencing order or citation
- Proof of anything you have completed: classes, payments, community service
- Records explaining a missed date, such as medical, work or travel records
- Your current address and contact information for the court
What to avoid
- Ignoring the warrant and hoping it goes away
- Calling the court or police to discuss the facts of your case before speaking with an attorney
- Driving or traveling more than necessary while a warrant is active, when it can be addressed first
- Assuming that an old warrant has been cleared without confirming it
Do not wait for the warrant to find you. Call Marcus at (619) 876-0992 to find out what the warrant is for and what your options may be.
Out-of-county warrants and moving while on probation
Warrants and probation do not stop at county lines, and many people in San Diego have cases elsewhere in California.
Warrants from other counties
A warrant issued by one county court can be enforced anywhere in the state. If you are stopped in San Diego on a warrant from another county, you may be held until the other county arranges to take custody, which can take time. A warrant from another county is generally resolved in the court that issued it. Marcus handles matters throughout San Diego County and, for southwest Riverside County, at the Southwest Justice Center in Murrieta, which covers Temecula, Murrieta, Lake Elsinore, Menifee and Perris. That makes him a practical option for people who live in one area and have a case in the other.
Warrants from other states
Warrants from other states can also lead to an arrest in California, and they involve additional procedures. If you know of an out-of-state warrant, get advice before you travel.
Moving while on probation
If you are on formal probation and need to move to another California county, the court can transfer your probation to the county where you live under Penal Code section 1203.9. Moving to another state while on supervised probation generally requires approval through an interstate process. Moving without following these steps can itself become a violation, so plan the move with your attorney and probation officer first.
Probation violations after a DUI
DUI probation in California is usually summary probation, but it is longer than most misdemeanor probation and comes with conditions specific to DUI cases.
Common DUI probation conditions
DUI probation often includes completing a DUI program, not driving with any measurable alcohol in your system, not refusing a chemical test if lawfully asked to take one, and not driving without a valid license and insurance. Some cases also include an ignition interlock device.
When a violation is alleged
A new DUI arrest while on probation can lead to both a new case, often charged as a second or third DUI, and a probation violation. Driving with a small amount of alcohol, even below the usual legal limit, can be a violation of DUI probation and can also lead to separate action by the DMV. Late program completion is another common issue, and it is often fixable if handled early.
The DMV side
The DMV process is separate from the court case and has short deadlines. See DUI defense and the 10-day DMV hearing deadline.
Early termination and changes to probation
Probation is not always fixed for its full term. California law gives the court power to change or end it in the right circumstances.
Early termination under PC 1203.3
Penal Code section 1203.3 allows the court, at any time during probation, to terminate it early and discharge the person when the ends of justice would be served and the person's good conduct and reform justify it. Early termination is discretionary. The prosecution receives notice of the request and can respond.
What helps a request
Requests are generally stronger when all or most conditions have been completed, restitution has been paid or is on track, there have been no violations, and there is a concrete reason early termination would help, such as a job opportunity, a professional license application or a move. Early termination generally does not erase restitution obligations, and some offenses have their own restrictions. Marcus can tell you whether a request is realistic in your situation.
Timing a request
There is no fixed point at which a request becomes appropriate, but courts generally want to see a meaningful period of good conduct and most conditions completed. Pairing an early termination request with a later request for dismissal under Penal Code section 1203.4 can be part of a plan to put the case fully behind you.
Modifying probation terms
The court can also modify probation conditions, for example to allow travel for work, change a program schedule, or adjust payment deadlines. A person on probation can ask the court for a modification. Asking before a problem occurs is generally far better than explaining a violation afterward.
After probation: clearing your record
Completing probation, or being discharged early, opens the door to record relief.
Dismissal under PC 1203.4
Penal Code section 1203.4 allows the court to set aside a conviction and dismiss the case once probation is complete. When every condition was fulfilled, relief is generally available as a matter of right. When there were violations along the way, relief is still often possible, but it is up to the court's discretion, so the full picture of your time on probation matters.
Reducing a wobbler
If the original conviction was a felony wobbler, a request under Penal Code section 17(b) to reduce it to a misdemeanor can often be made at the same time. See felony defense for more on reductions.
Limits of a dismissal
A dismissal helps with many private employers, but it does not erase the case for every purpose. See record sealing and expungement for what it does and does not do.
Working with Marcus
Marcus E. DeBose has defended San Diego clients since 2001 (State Bar No. 216328), and has been a partner at Tegnelia & DeBose, APC, the firm behind Email My Lawyer, since 2016. Many of the people he helps with probation and warrant issues are working, raising families and trying to put an old case behind them.
Learning what happened and why
His approach starts with a long first conversation about what happened and why. Probation violations rarely happen in a vacuum: a job change, an illness, a family emergency, or a misunderstanding about a deadline is often behind them. Marcus gathers the records that tell that story and presents it to the prosecutor and the judge.
Early in his career, Marcus carried a caseload of 125 felony cases at one time. That experience gave him a close view of how San Diego courts handle probation, violations and warrants day to day, and how a well-prepared explanation can change the result.
