The Short Answer
Assault and battery are two distinct legal wrongs that often happen together. Assault is the threat of harmful or offensive contact. Battery is the actual contact. A person can commit an assault without ever touching anyone, and in some situations a battery can occur without a separate assault, though the two are usually charged together.
The distinction matters in both criminal law and civil law. It affects what a prosecutor must prove, what penalties apply, and what a person can recover in a lawsuit.
Two Wrongs, Often Charged Together
In everyday speech, people say "assault" to mean a physical attack. In the law, the words carry narrower meanings. Assault covers the threat, and battery covers the contact. When someone swings a fist and connects, the conduct can be both: the swing is the assault and the impact is the battery.
Criminal codes in most states list assault and battery as separate offenses, and prosecutors commonly charge both. Some states combine them into a single statute, or use the term assault to cover what other states call battery. That is why the same conduct can be labeled differently depending on where it happens.
Assault: The Threat
An assault is generally an intentional act that causes a person to reasonably fear imminent harmful or offensive contact. The key words are intentional, reasonable, and imminent.
- Intent. The person must intend to cause the fear or intend to make contact. An accidental scare is not an assault.
- Reasonable fear. The victim must actually perceive a threat, and a reasonable person in the same situation would perceive it too. Words alone are usually not enough, but words combined with a movement or a weapon can be.
- Imminent. The threat must be immediate, not a vague promise to harm someone at some future time.
No physical contact is required. Raising a fist, pointing a weapon, or lunging at someone can be an assault if the other person reasonably expects to be struck.
Battery: The Contact
A battery is the intentional infliction of harmful or offensive physical contact on another person. The contact does not have to cause injury. A shove, a spit, or an unwanted touch can qualify if it is offensive to a reasonable sense of personal dignity.
- Intent. The person must intend the contact, or know with substantial certainty that it will occur. Intent to injure is not required.
- Harmful or offensive. The contact must be either physically harmful or offensive to an ordinary person.
- No consent. Contact that the person consented to, such as contact within the rules of a sport, is generally not a battery.
Battery can occur even if the victim was asleep or unaware at the moment of contact, because the wrong is the unconsented touching itself.
Assault vs Battery at a Glance
| Assault | Battery | |
|---|---|---|
| Core idea | Threat of contact | Actual contact |
| Physical touching | Not required | Required |
| What must be shown | Fear of imminent harm | Harmful or offensive touching |
| Example | Raising a fist and stepping forward | Punching, shoving, or spitting |
| Can stand alone | Yes | Yes, as with a contact from behind |
Criminal Assault and Battery
There is no single federal assault statute that covers an ordinary street fight. Most assault and battery cases are prosecuted under state law, and each state sets its own definitions and penalties. Some states increase the charge based on the victim, the injury, or the use of a weapon. Assault on a police officer, domestic assault, and assault with a deadly weapon are common examples of elevated charges.
Federal law does criminalize certain assaults in specific contexts, such as assaults on federal officers, in federal facilities, or on federal property. These appear in Title 18 of the U.S. Code and can be found through the Government Publishing Office at govinfo.gov. State criminal codes are published by each state legislature. The Texas Penal Code and the California Penal Code both define assault and battery, for instance, but with different wording and different penalty ranges.
Penalties depend on the state and the level of the offense. A simple misdemeanor assault may carry fines, probation, or a short jail term, while aggravated assault can be a felony with prison time. Because the labels and ranges differ so much, always check the statute in the jurisdiction where the conduct occurred.
Civil Assault and Battery
Assault and battery are also torts, which means the victim can sue for money damages even if no criminal charge is filed. The standards are similar but not identical. In a civil case the plaintiff must prove the elements by a preponderance of the evidence, a lower burden than the beyond a reasonable doubt standard used in criminal cases.
The victim may recover for medical bills, lost wages, pain and suffering, and in some cases punitive damages. A single act can lead to both a criminal prosecution and a civil lawsuit. The two cases proceed separately, and the outcome of one does not automatically decide the other.
Common Defenses
- Consent. If the person agreed to the contact, there is generally no battery. Contact within the rules of a sport is the classic example.
- Self-defense. A person may use reasonable force to defend against an imminent threat. The force must be proportional, and the person must reasonably believe it is necessary.
- Defense of others. Similar rules can apply when a person uses force to protect someone else from harm.
- Lack of intent. Because both offenses require intent, an accidental collision or an unintentional scare is usually neither assault nor battery.
- Privilege. Certain people, such as police officers making a lawful arrest, may use limited force that would otherwise be a battery.
Related Offenses
Several offenses are easy to confuse with assault and battery. Menacing and criminal threats are close to assault but focus on placing a person in fear. Attempted battery is an incomplete battery. Sexual assault and domestic violence are separate statutory categories with their own procedures and penalties. Aggravated assault usually adds a weapon, serious injury, or a protected victim.
Why the Distinction Matters
Knowing whether conduct is an assault, a battery, or both affects charging decisions, defenses, and damages. It also matters for record keeping, since a conviction for one can carry different collateral consequences than the other. Definitions vary by state, and courts continue to interpret them. When a real dispute is involved, the exact wording of the local statute and the case law interpreting it are what control.
