In law, battery is the intentional, nonconsensual harmful or offensive physical contact with another person. That short formula is the working definition of battery in law, and it holds whether the case is prosecuted as a crime by the government or filed as a civil tort by the person who was touched. The contact does not need to leave a bruise, cause pain, or produce any lasting injury. Any unwanted physical interference can qualify, from a shove to a spit to a yank on someone’s sleeve.
The Three Elements
Every battery claim rests on three things, and all three have to be present.
Intent. The person must have meant to make the contact happen, or at least known it was substantially certain to occur. The law does not require a desire to injure. It requires the deliberate choice to perform the act that led to the touching. That is what separates battery from an accidental bump on a crowded sidewalk.
Contact. There must be actual physical contact, however slight. A light push counts. A grab of the wrist counts. Spitting on someone counts. No visible mark is needed.
No consent. The other person did not agree to the interaction. Where genuine consent exists, the contact is generally not battery, which is why a boxing match does not end in criminal charges.
Criminal and civil battery add slightly different gloss on top of these elements. In the criminal version, the contact must be “unlawful,” meaning not legally justified. Federal law, for example, defines the basic offense of assault by striking, beating, or wounding within federal jurisdiction.1Office of the Law Revision Counsel. 18 USC 113 – Assaults Within Maritime and Territorial Jurisdiction In the civil version, the question is whether the contact was “harmful or offensive,” judged by a reasonable-person standard. Not what the particular victim found upsetting. What an ordinary person would consider a violation of personal dignity. A friendly tap on the shoulder in a crowded room would not qualify. Cornering someone and poking them in the chest likely would.
What Counts as Physical Contact
Battery reaches further than a punch or a slap. Courts have long held that anything closely connected to a person’s body is, legally speaking, part of that person. Grabbing a purse strap while the owner is wearing it is contact with the owner. Knocking a phone out of someone’s hand is contact with them. Yanking a chair out from under someone is contact.
Indirect contact also qualifies. Throwing a rock, spraying someone with a hose, releasing a dog on someone, or setting a trap that eventually makes contact all count. The question is whether the defendant set in motion a force that resulted in contact with the victim. The delivery method does not matter.
Assault Versus Battery
People say “assault and battery” so often that the two run together, but they are distinct ideas. Assault is about fear. It occurs when someone’s conduct puts another person in reasonable apprehension of imminent harmful contact. Battery is about contact. It occurs when the harmful or offensive touching actually happens. You can commit assault without battery by swinging a fist and missing. You can commit battery without assault by shoving someone from behind who never saw it coming.
Many states have merged the two into a single offense called “assault,” following the approach of the Model Penal Code, which folded battery into its assault statute. The underlying distinction still matters in civil lawsuits and in states that keep the offenses separate.
Criminal Battery and Civil Battery
The same physical act can set off two separate legal proceedings, and the same defendant can face both at once.
A criminal battery case is brought by the government. A prosecutor, not the victim, decides whether to file charges. The prosecution must prove every element beyond a reasonable doubt. Conviction can mean jail or prison time, fines, probation, and a criminal record.
A civil battery lawsuit is filed by the victim and seeks money damages. The burden of proof is lower: preponderance of the evidence, meaning more likely than not. A victim can win the civil case even if the criminal case ended in acquittal, because the civil bar is easier to clear. Damages typically include compensation for medical bills, lost wages, and pain and suffering. Where the conduct was especially reckless or malicious, courts may add punitive damages meant to punish the defendant and discourage similar behavior.
Simple Battery and Aggravated Battery
Not every battery charge carries the same weight. Simple battery covers minor contact without serious injury and is a misdemeanor in most states. Jail sentences up to six months or a year are common, along with fines ranging from a few hundred to several thousand dollars. First offenses with no aggravating factors often result in probation.
Aggravated battery is typically a felony. The usual triggers are the use of a deadly weapon such as a firearm, knife, or vehicle; serious bodily injury such as broken bones, disfigurement, or loss of organ function; and victim status, where the target is a law enforcement officer, firefighter, paramedic, elderly person, child, or other protected class. State felony sentences for the most serious aggravated offenses generally fall in a range of two to twenty years. Federal law sets a ten-year maximum for assault resulting in serious bodily injury and the same maximum for assault with a dangerous weapon with intent to do bodily harm.1Office of the Law Revision Counsel. 18 USC 113 – Assaults Within Maritime and Territorial Jurisdiction
Domestic Battery
When battery occurs between spouses, dating partners, family members, or cohabitants, many states reclassify or enhance the charge. A domestic battery designation can trigger mandatory arrest policies, no-contact orders that force the accused to leave a shared home, and court-ordered treatment programs.
One consequence catches many defendants off guard. Federal law permanently prohibits anyone convicted of a misdemeanor crime of domestic violence from possessing firearms or ammunition.2Office of the Law Revision Counsel. 18 USC 922 – Unlawful Acts The ban applies even when the underlying offense was only a misdemeanor, and it applies in every state regardless of local gun laws.
Defenses That Negate Battery
Having the elements technically present does not always mean the defendant is liable or guilty. Several recognized defenses can defeat a battery claim.
Self-Defense
The most frequently raised defense. The person claiming it generally must show that they faced an imminent threat of harm, that they genuinely believed force was necessary to protect themselves, and that the force used was proportional to the threat. Punching someone who is lunging with a weapon is likely proportional. Continuing to strike after the threat has stopped is not. A person who started the fight usually cannot claim self-defense unless they clearly tried to withdraw and the other person kept attacking.
Defense of Others
The same principles apply when the force is used to protect a third party. The threat to the other person must be imminent and the force must be reasonable. The test is essentially the same one used for self-defense.
Consent
Consent eliminates the battery claim entirely, because an element of the offense is that the contact was unwanted. Consent can be explicit, like signing a waiver before a medical procedure, or implied, like stepping onto a football field. Athletes are generally understood to have consented to the contact inherent in their sport, but contact that goes well beyond the rules, like punching an opponent in a soccer match, falls outside that implied consent. The same logic applies in medicine: a patient who consents to knee surgery has not consented to the surgeon operating on a shoulder.
Defense of Property
Reasonable force to prevent theft or destruction of property is allowed, but this defense is narrower than self-defense. Deadly force to protect property alone, with no threat to a person, is not justified in most jurisdictions.
Transferred Intent
Battery law contains a doctrine that extends the definition in a way many people find surprising. If someone intends to commit battery against one person but accidentally strikes another, they are still liable for battery against the unintended victim. The law treats the original intent as transferring from the person who was targeted to the person who was actually hit. Throw a bottle at Person A, miss, and hit Person B, and the battery is complete against Person B. The doctrine also runs across related offenses, so intent to commit assault can support a battery charge against the unintended victim.
