Key facts: Assault requires apprehension of imminent harmful contact, battery requires the contact itself, and penalties rise sharply when aggravating factors such as a deadly weapon or serious injury are involved.[1][2][3]

Assault and battery are related but distinct offenses under American law. Assault generally involves putting another person in reasonable apprehension of imminent harmful or offensive contact, while battery involves the actual harmful or offensive contact itself.[1][2]Many jurisdictions merge the two into a single offense, often labeled assault, while others keep them separate crimes.[2]

Definitions

Assault is generally defined under common law as an intentional act that puts another person in reasonable apprehension of imminent harmful or offensive contact, and no physical injury is required.[1]Battery is the intentional infliction of harmful or offensive physical contact with another person without consent.[2]In criminal law, assault may refer either to the act of causing apprehension of harmful contact or to the harmful contact itself, depending on the jurisdiction, and some states merge assault and battery into a single offense.[1][2]These offenses fall within the broader category of violent crimes, and understanding them often requires familiarity with the general elements of a crime.

Assault

A prima facie case for assault has three components: the defendant acts, the defendant intends to cause the victim to apprehend imminent harmful or offensive contact, and the defendant's act causes the victim to reasonably apprehend such contact.[1]Intent in this context means the act is not accidental, but motive is immaterial; it does not matter whether the goal was merely to scare the victim or whether the act was meant as a joke.[1]"Reasonable apprehension" refers to the victim's reasonable belief that imminent harmful or offensive contact will occur, and the victim does not need to prove actual fear, only awareness that such contact might occur.[1]If the victim and the person acting do not know each other, the standard is what an ordinary reasonable person in the victim's circumstances would have believed, though special knowledge between the parties may affect the analysis.[1]Some jurisdictions label assault as attempted battery, and the two are often paired as "assault and battery," with assault referring to the apprehension-causing act and battery referring to the actual contact.[1]State definitions vary: for example, California law defines assault as "an unlawful attempt, coupled with a present ability, to commit a violent injury on the person of another," while New York defines third-degree assault around intentional, reckless, or criminally negligent infliction of physical injury.[1]Readers who want background on how prosecutors must prove mental state can review the discussion of mens rea.

Battery

Civil battery requires that the defendant acted, intended to cause contact with the plaintiff, and that the contact was harmful or offensive and resulted in harm or offense.[2]A harmful contact causes physical impairment or injury, while an offensive contact is one that would offend a reasonable sense of personal dignity under an objective standard; even an otherwise inoffensive contact can be deemed offensive if the actor knew of and exploited the victim's special sensitivity.[2][1]A plaintiff does not need to prove actual damages, because the law treats the harmful or offensive contact itself as an injury, allowing nominal damages and, where malice is present, punitive damages.[2]Under the eggshell skull rule, a defendant remains liable for all consequences of the contact even if the victim had an unforeseen preexisting condition.[2]In criminal law, many jurisdictions merge assault and battery into a single offense called assault, though some retain battery as a separate crime defined as the unlawful application of force resulting in bodily injury or offensive contact.[2]Criminal battery is generally treated as a general intent crime, meaning it does not require proof of specific intent beyond the intent to commit the contact.[2]

Aggravated assault

Assault committed under aggravating circumstances may be raised to aggravated assault, and aggravated battery similarly involves additional factors such as use of a deadly weapon or causing serious bodily harm, which carry harsher penalties.[1][2]Federal law illustrates how aggravating facts increase punishment: assault with intent to commit murder or certain sexual offenses carries a longer maximum prison term than assault by striking, beating, or wounding, or simple assault.[3]Federal law also singles out assault with a dangerous weapon committed with intent to do bodily harm, assault resulting in serious bodily injury, and assault resulting in substantial bodily injury to a spouse, intimate partner, dating partner, or a person under 16, each carrying its own maximum penalty.[3]Because grading of aggravated offenses varies significantly, the line between a misdemeanor and a felony assault charge depends heavily on the facts and the jurisdiction.

Federal assault law

Federal assault law applies within the special maritime and territorial jurisdiction of the United States and sets out a graduated scale of offenses and penalties.[3]These range from simple assault, punishable by a fine or imprisonment of not more than six months (or up to one year if the victim is under 16), up to assault with intent to commit murder or certain sexual offenses, punishable by a fine, imprisonment for not more than 20 years, or both.[3]The statute also defines specific terms used in grading these offenses, including "serious bodily injury," "substantial bodily injury," "strangling," and "suffocating," and addresses assaults involving strangulation or suffocation of a spouse, intimate partner, or dating partner.[3]This federal scheme sits alongside the much larger body of state assault and battery law, and both can be relevant depending on where and against whom the conduct occurred; readers interested in the federal system generally can review federal crimes.

Defenses

Consent, whether express or implied, is recognized as a defense to battery, such as consent arising from participation in a sport.[2]Self-defense and defense of others are also recognized defenses to battery, so long as the response is reasonable under the circumstances.[2]There is some disagreement among jurisdictions regarding the role of consent in assault cases specifically.[1]Anyone facing an assault or battery charge can ask for a lawyer, and general information about the stages that follow an arrest is available in the overview of arrest and the broader discussion of criminal defenses.

Common questions

What is the difference between assault and battery?

Assault refers to the act that causes a victim to reasonably apprehend imminent harmful or offensive contact, while battery refers to the actual harmful or offensive contact itself.[1]Many jurisdictions merge the two into a single offense, often called assault, though some states keep battery as a separate crime.[2]

What makes an assault aggravated?

Assault committed under aggravating circumstances, such as use of a deadly weapon or causing serious bodily harm, may be classified as aggravated assault or aggravated battery, which carries harsher penalties than simple assault.[1][2]Under federal law, for example, assault with a dangerous weapon and assault resulting in serious bodily injury each carry higher maximum sentences than simple assault.[3]

Can words alone be an assault?

Assault requires an act that causes the victim to reasonably apprehend imminent harmful or offensive contact, and the threatened contact must be certain or likely to occur very soon.[1]Courts have found that a threat combined with surrounding acts and circumstances can reasonably put someone in apprehension of imminent bodily harm, as in the Kansas case of Vetter v. Morgan.[1]

Does the victim have to be physically injured for there to be an assault?

No physical injury is required for assault; the actor must have intended to cause a harmful or offensive contact and the victim must have been put in immediate apprehension of such contact.[1]For civil battery, however, actual contact must occur, though the victim does not need to prove actual damages because the harmful or offensive contact itself is treated as an injury.[2]

Is consent a defense to assault or battery?

Consent, whether express or implied, is a recognized defense to battery, such as consent implied by participating in a sport.[2]There is some disagreement among jurisdictions about the role of consent in assault cases.[1]
