Assault and Battery Defense

Assault, under Penal Code 240, is an unlawful attempt, coupled with the present ability, to commit a violent injury on someone else. No contact is required. Nobody has to be touched, hurt, or even frightened. What matters is that you did something that would probably result in force being applied, and that you were actually able to do it at the time.

Simple assault is a misdemeanor carrying up to six months in county jail and a fine of up to $1,000.

Battery, under Penal Code 242, is any willful and unlawful use of force or violence on another person. Here contact is required, but injury is not. A shove, a poke, a thrown drink, or grabbing someone's shirt is enough. California courts treat any harmful or offensive touching as sufficient, however slight.

Simple battery is a misdemeanor carrying up to six months in county jail and a fine of up to $2,000.

You can be charged with both for a single incident, and frequently are.

The simple versions are misdemeanors. Several related statutes are not, and which one gets filed depends heavily on the injury alleged and on what object, if any, was involved.

Battery causing serious bodily injury, Penal Code 243(d). This is a wobbler. As a misdemeanor it carries up to one year in county jail. As a felony it carries two, three, or four years.

Assault with a deadly weapon, Penal Code 245(a)(1). A wobbler carrying up to one year as a misdemeanor, or two, three, or four years as a felony. "Deadly weapon" is broader than most people expect. California courts have found bottles, bats, vehicles, and in the right circumstances a shod foot to qualify. The object doesn't have to be designed as a weapon; it has to be used in a way capable of producing great bodily injury.

Assault by means of force likely to produce great bodily injury, Penal Code 245(a)(4). A wobbler with the same ranges, and no weapon required at all. This is how a fistfight becomes a felony.

Battery on a peace officer, Penal Code 243(b) and 243(c)(2). Where no injury results, a misdemeanor carrying up to one year. Where the officer is injured, a wobbler with felony exposure of 16 months, two years, or three years.

Assault with a firearm, Penal Code 245(a)(2). Covered in more detail on our firearm violations page, and carrying its own exposure and enhancements.

Great bodily injury enhancement, Penal Code 12022.7. Where great bodily injury was personally inflicted, this adds three years or more on top of the underlying felony.

Where the alleged victim is a spouse, former spouse, cohabitant, dating partner, or the parent of your child, different statutes apply entirely, including Penal Code 243(e)(1) and Penal Code 273.5. Those cases carry mandatory programs and consequences the general assault statutes do not, and they are addressed on our domestic violence page.

These two phrases appear across the assault and battery statutes, and they are not interchangeable. They are separate legal standards with separate definitions, they attach to different code sections, and a case can meet one without meeting the other.

This matters because the difference between a bruise and a serious bodily injury is the difference between a misdemeanor and felony exposure. That determination is made from medical records, photographs, and often from a single line in a police report written by someone who is not a physician.

Soreness, bruising, and minor cuts don't automatically qualify. Where the injury allegation is what elevated your charge, the medical evidence behind it deserves close examination rather than acceptance.

If you have been reading about your charge online, you have probably encountered flat statements that these offenses are strikes under California's Three Strikes law. Some sources say assault with a deadly weapon is a strike. Others say battery with serious bodily injury is. Some say both. They cannot all be right, and the confusion has real consequences, because a strike doubles the sentence on any future felony and limits custody credits so that roughly 85 percent of a sentence is served.

Here is the honest version. A felony conviction under Penal Code 245(a)(1), assault with a deadly weapon, is a serious felony and does carry a strike. For other offenses in this family, including battery with serious bodily injury under Penal Code 243(d) and assault by means of force likely to produce great bodily injury under Penal Code 245(a)(4), whether a strike attaches depends on what was specifically alleged and found true in the case, particularly whether great bodily injury was personally inflicted.

That distinction is not a technicality. It's frequently the most valuable thing negotiated in an assault case, because two charges carrying identical maximum terms can have completely different long-term consequences. Which section a plea is entered to, and which allegations are dismissed, can matter far more than the sentence attached to it.

If someone has told you flatly what your charge means for strike purposes without looking at the specific allegations in your case, get a second opinion.

In assault and battery cases, self-defense is not a mitigating factor. It is a complete defense, meaning that if it applies, no crime was committed.

California law asks three questions. Did you reasonably believe you were in imminent danger of being harmed or unlawfully touched? Did you reasonably believe force was necessary to stop that danger? Did you use no more force than was reasonably necessary?

Two features of this matter enormously in practice.

Reasonableness is judged from your position at the time, not in hindsight. What you knew, what you could see, and what had happened before that moment all count. A jury is not permitted to evaluate your decision with information you did not have.

The same rules apply to defending someone else. Protecting another person from harm you reasonably believed was imminent is defended on the same terms.

The practical problem with self-defense is evidentiary. Police arriving at a fight often take the account of whoever called first or whoever appears more injured, and that account becomes the report. Documenting your own injuries, immediately, is the single most useful thing a person in that position can do.

For misdemeanor assault and battery cases, California has diversion programs that can result in the charges being dismissed rather than resulting in a conviction.

Misdemeanor diversion under Penal Code 1001.95 allows a judge to divert certain misdemeanor cases, including simple assault and battery, over the prosecutor's objection. Completion results in dismissal. Domestic violence offenses are excluded.

Mental health diversion under Penal Code 1001.36 may be available where a qualifying mental health condition played a significant role in the offense.

Military diversion under Penal Code 1001.80 may be available to current and former service members on misdemeanor charges.

Eligibility depends on the charge, the record, and the specific facts, and diversion is not automatic. It has to be requested and argued for. But in a first-offense misdemeanor case, this path is often more valuable than any plea negotiation, and it's worth asking about before anything is resolved.

We reconstruct who started it. Assault cases are frequently mutual incidents that got characterized one way because of who called 911 or who was still at the scene when police arrived. Witnesses who saw the beginning of an altercation are the most valuable evidence in these cases and the least likely to appear in a report.

We document our client's injuries immediately. Photographs, urgent care records, and booking photos. In a self-defense case this evidence is decisive, and it disappears within days as bruises fade.

We push hard on the injury allegation. Whether an injury meets the legal standard that elevated your charge is a question the medical records answer, not the police report. Where the elevation doesn't hold, the case becomes a different case.

We fight over which section a case resolves under. Given how much the strike consequences differ between statutes carrying identical terms, the section named in a disposition can matter more than the sentence. This is not a detail we treat as an afterthought.

We pursue diversion where it fits. In first-offense misdemeanor cases, a dismissal after completing a program is a better outcome than any conviction, and it has to be raised early.

We work the wobbler. Getting a case filed or reduced as a misdemeanor under Penal Code 17(b) changes employment, licensing, immigration exposure, and firearm rights.

We move on video and witnesses in the first days. Bar cameras, business cameras, doorbell cameras, phone footage from bystanders. Retention windows are short and nobody preserves this for you.

The custody exposure on these charges is often modest. The consequences that follow the case are not, and they're the real reason the misdemeanor-versus-felony fight matters.

Your firearm rights. A felony conviction means a lifetime prohibition on possessing firearms in California. Several of the misdemeanors in this family, including assault with a deadly weapon and brandishing, trigger a ten-year prohibition under Penal Code 29805. People are regularly surprised to learn a misdemeanor did this, usually years later when they try to buy a firearm.

Your immigration status. Assault and battery convictions can be treated as crimes involving moral turpitude under federal immigration law — a federal category with no statutory definition, decided by the wording of the statute rather than by what happened — and a felony conviction carrying a sentence of a year or more can raise aggravated felony exposure. For anyone who is not a United States citizen, this has to shape the defense from the first conversation, including what sentence length any plea carries. It is not something to address after a plea is entered.

Your professional license. Licensing boards ask about convictions, and a violent-offense conviction reads differently to a board than most other offenses. Nurses, teachers, contractors, security personnel, and anyone in a licensed trade should raise this early.

Employment and housing. A conviction involving violence is among the categories employers and landlords screen for most aggressively.

And a strike, in some cases. As above, a felony conviction under Penal Code 245(a)(1) carries a strike, which doubles the sentence on any future felony and limits custody credits. This is the consequence that outlasts all the others.

A reduction to a misdemeanor under Penal Code 17(b), or a dismissal through diversion, changes several of these outcomes. Which is why those are worth pursuing even in a case where nobody is going to jail.

Photograph your injuries today. Every mark, from multiple angles, with timestamps. Get seen at urgent care even if you think you're fine, because a medical record created that day is worth more later than your description of what happened.

Do not contact the other person. Not to apologize, not to explain, not through mutual friends. Contact can create new charges and it will be read as consciousness of guilt.

Get names and numbers of anyone who saw how it started. Not just how it ended. This is the evidence that most often decides these cases and it evaporates quickly.

Preserve video and messages, including anything unflattering. Deleting is worse than whatever the content shows.

Do not post about it.

Say nothing about the incident to police without a lawyer. If charges haven't been filed yet, that window is the most useful stage of the case. In a self-defense case, an explanation given at the scene can undercut the defense you would otherwise have.
