Assault

The short version

Assault and battery are criminal charges that involve harm or the threat of harm to another person. "Assault" usually refers to the threat or attempt to cause harm, while "battery" is the actual physical contact. These laws protect people from violence and the fear of violence, and understanding them helps you know your rights and responsibilities if you are accused or are a victim.

The law this is built on

Every point below comes from the authority named next to it. Verify the current text before relying on it.

This amendment says you cannot be forced to testify against yourself and guarantees due process of law. It also prohibits double jeopardy, meaning you can't be tried twice for the same crime.
Why it matters: You have the right to remain silent and to a fair legal process if charged with assault or battery.
U.S. Const. amend. VI
This amendment guarantees the right to a speedy and public trial, an impartial jury, to be informed of the charges, to confront witnesses, and to have legal counsel. This applies to criminal prosecutions for assault or battery.
Why it matters: You have fundamental rights during any criminal case, including a lawyer, a jury, and knowing the specific charges against you.

Words you need to know

Assault (Simple): Usually defined as an intentional act that causes another person to reasonably fear immediate harmful or offensive contact. Actual physical contact is not required for an assault charge.
Battery: Typically defined as the intentional, unlawful physical contact with another person without their consent. Battery requires actual physical touching.
Aggravated Assault: A more serious form of assault, often involving the use of a dangerous weapon, intent to commit another serious crime (like rape), or causing serious bodily injury. It carries harsher penalties than simple assault.
Intent: For assault and battery, intent usually means you meant to perform the action that caused the fear or contact, even if you didn't mean to cause serious harm. Some states also consider reckless actions as intent.
Serious Bodily Injury: This term is often used in aggravated assault charges and typically refers to injury that creates a substantial risk of death, causes serious permanent disfigurement, or results in a protracted loss or impairment of the function of any bodily member or organ.
Self-Defense: A legal defense where you can use reasonable force to protect yourself or another person from immediate harm. The amount of force used must be proportional to the threat.

How the process actually works

1
Incident Occurs
When the alleged assault or battery happens
An event involving a threat of harm or actual physical contact takes place. This could be an argument that escalates or an unprovoked attack.
2
Police Investigation
Immediately after the incident, or when reported
Law enforcement may be called to the scene. They will gather evidence, interview witnesses, and potentially make an arrest. They need probable cause to arrest you (U.S. Const. amend. IV).
3
Arrest & Booking
Soon after the investigation and decision to arrest
If arrested, you are taken to the police station for booking, which includes fingerprinting and photographs. You have the right to remain silent and to request a lawyer (U.S. Const. amend. V, VI).
4
Initial Appearance & Bail
Within 24-72 hours of arrest, varies by state
You will appear before a judge, who will inform you of the charges and set bail if applicable. Bail should not be excessive (U.S. Const. amend. VIII).
5
Discovery & Motions
Weeks to months after arrest, varies by complexity
Your attorney will gather evidence from the prosecution (discovery) and may file motions to challenge evidence or dismiss the case. Both sides prepare for trial.
6
Plea Bargaining or Trial
Months after initial appearance, depending on court schedule
You may enter a plea agreement with the prosecution, or the case will proceed to trial. At trial, the prosecution must prove guilt beyond a reasonable doubt.
7
Sentencing
Immediately after conviction or weeks later
If you are convicted or plead guilty, the judge will determine the punishment, which could include fines, probation, or jail time. Punishments must not be cruel or unusual (U.S. Const. amend. VIII).

Deadlines that can end your case

Statute of Limitations (Misdemeanor Assault)
Varies by state, typically 1-3 years from the date of the incident
If charges are not filed within this window, you generally cannot be prosecuted for that specific crime.
Statute of Limitations (Felony Assault/Aggravated Assault)
Varies by state, typically 3-10 years, some serious felonies have no limitation
Prosecutors must file charges within this time frame, or the case cannot proceed.
Speedy Trial Right
Varies by state and jurisdiction, often 90-180 days for misdemeanors if in custody, longer for felonies
If your trial is delayed beyond a certain period without good reason, your case might be dismissed (U.S. Const. amend. VI).

Costly mistakes

✕Talking to police without an attorney present after being arrested or accused. You have the right to remain silent (U.S. Const. amend. V).
✕Failing to seek medical attention for injuries, whether you are the victim or claiming self-defense. This can weaken your case or defense.
✕Trying to contact the alleged victim or witnesses after being told not to, which can lead to new charges or violate bail conditions.
✕Not understanding the difference between assault and battery definitions, which vary by state and impact the charges.
✕Not being aware of the specific state laws regarding self-defense, which can vary widely.
✕Ignoring court summons or failing to appear, which can lead to a warrant for your arrest.

Your checklist

If accused, immediately stop talking to police and clearly state you wish to exercise your right to remain silent and have an attorney (U.S. Const. amend. V, VI).
Do not resist arrest, even if you believe it is unlawful. Your rights are protected through the legal process (U.S. Const. amend. IV).
Seek legal counsel as soon as possible. An attorney can explain your rights and the specific charges against you.
If you are the victim, report the incident to law enforcement and seek medical attention for any injuries.
Document everything: dates, times, names of officers, any statements made, and preserve any evidence you may have.
Review your state's specific definitions of assault, battery, and self-defense, as these laws vary widely.
Understand the conditions of your bail or release, if applicable, and follow them strictly to avoid further legal trouble.

Common questions

What is the difference between assault and battery?

Generally, assault is the threat or attempt to cause physical harm or offensive contact, making someone fear for their safety. Battery is the actual unwanted physical contact. Some states combine these into a single 'assault' charge, but the core distinction is the presence of physical contact. For example, 18 U.S.C. § 113 distinguishes 'assault' from 'assault by striking, beating, or wounding.'

Can I be charged with assault if I didn't touch anyone?

Yes, in many places, you can be charged with simple assault if you made someone reasonably believe they were about to be harmed, even without physical contact. The fear of imminent harm is often enough for an assault charge.

What makes an assault 'aggravated'?

Aggravated assault is typically a more serious felony charge. It involves factors like using a dangerous weapon, intending to commit another felony (like robbery), causing serious bodily injury, or assaulting certain protected individuals (e.g., police officers). These factors increase the potential penalties significantly.

What if I acted in self-defense?

Self-defense is a legal justification for using force against another person. You can use reasonable force to protect yourself or another person from imminent harm. The force used must be proportional to the threat. For example, you generally can't use a deadly weapon to defend against a simple shove.

What are the potential penalties for assault and battery?

Penalties vary widely by state and the severity of the charge. Simple assault or battery might result in fines, probation, or up to a year in jail (misdemeanor). Aggravated assault can lead to years or decades in state prison, significant fines, and a felony record. The U.S. Constitution's Eighth Amendment protects you from cruel and unusual punishment, and excessive bail.

How this changes by state

Criminal law, including definitions of assault and battery, varies significantly from state to state. While the federal government has some laws (like 18 U.S.C. § 113), most assault and battery cases are prosecuted under state criminal codes. Each state has its own specific definitions for simple assault, aggravated assault, and battery, including what constitutes 'bodily injury,' 'dangerous weapon,' and the elements required for intent. Penalties also differ widely. To understand the exact laws that apply to you, you must consult your state's specific criminal statutes. You can often find these by searching online for '[Your State Name] criminal code assault' or by contacting a local legal aid organization or attorney.

When you need a lawyer

You should seek legal counsel immediately if you are questioned by the police regarding an assault or battery, if you have been arrested, or if you are a victim and need help understanding your options. An attorney can protect your rights, explain the charges, negotiate with prosecutors, and represent you in court. If you are facing charges, a lawyer is crucial to navigate the complex legal system and ensure you receive a fair process (U.S. Const. amend. VI).
