Assault and battery in the third degree is the least serious tier of assault and battery charges, covering conduct where a person intentionally or recklessly causes minor physical injury to someone else without using a deadly weapon and without targeting a protected victim. In most states it is a misdemeanor, punishable by up to a year in jail, fines commonly ranging from $1,000 to $5,000, probation, or some combination of the three. Not every state uses the “degree” label. Many call the same offense “simple assault” or “simple battery,” but the concept is the same: it sits at the bottom of the severity ladder, below offenses involving serious injuries, weapons, or vulnerable victims.
What Puts a Charge in the Third Degree
States that number their assault statutes reserve first degree for the worst conduct: attacks that cause life-threatening injuries, involve a deadly weapon, or are committed with intent to kill or permanently disfigure. Second degree generally covers serious physical injury or the use of a dangerous weapon without a specific intent to kill. Third degree is what is left after those higher categories are stripped away — intentional or reckless conduct that causes ordinary physical injury, with no weapon and no intent to inflict devastating harm.
The dividing line most often turns on the injury itself. Federal law defines bodily injury broadly to include a cut, bruise, burn, physical pain, illness, or any impairment of a bodily function, no matter how temporary. Serious bodily injury is a much higher bar, requiring a substantial risk of death, extreme physical pain, obvious and lasting disfigurement, or long-term loss of function in a limb, organ, or mental faculty.1Office of the Law Revision Counsel. 18 USC 1365 – Tampering With Consumer Products A bloody nose or bruise from a punch lands in the bodily-injury category. A fractured skull from the same punch crosses into serious bodily injury and bumps the charge up.
Two other concepts sit inside the “assault and battery” label. Assault is the threat — an act that makes another person reasonably believe they are about to be struck. No contact is required. Battery is the contact itself, made intentionally in a harmful or offensive way without consent. Some states have merged them under a single assault statute; others still charge them separately. When you see the combined phrase, the prosecution is alleging both.
What the Prosecution Has to Prove
A third-degree charge has three parts, each of which the prosecution must establish beyond a reasonable doubt.
Mental State
The prosecutor does not have to prove the defendant planned to hurt anyone badly. The mental state can be intentional (meaning the person meant to cause some physical injury), reckless (meaning the person knew their conduct created a substantial risk of injury and did it anyway), or, in some jurisdictions, criminally negligent (meaning a reasonable person would have recognized the risk).2Congress.gov. Mens Rea: An Overview of State-of-Mind Requirements for Federal Criminal Law Recklessness and negligence are not the same: recklessness means you knew and ignored the risk, negligence means you should have known but didn’t.
The Act and the Injury
The defendant must have committed a physical act, or, for assault alone, an act that put someone in reasonable fear of imminent contact. The injury that resulted must qualify as ordinary bodily injury, not serious bodily injury. The actual medical outcome, not what the defendant intended, often decides the degree. A punch thrown as a warning shot that happens to break an orbital bone can jump from third to second degree because of the fracture alone.
No Aggravating Factors
Third degree also requires the absence of factors that would push the charge higher: use of a deadly weapon, an attack on a law enforcement officer or other protected person (a child, elderly person, or emergency responder), or an assault committed during another felony. If any of those are present, the charge escalates even when the physical injury is minor.
Typical Situations That Lead to These Charges
Third-degree cases tend to follow a pattern. A confrontation escalates, someone gets physical, and the injury is real but not severe. A shove during an argument that leaves a bruise. A slap in a heated dispute. A bar-fight punch that produces a black eye or a split lip but no broken bones. An unwanted grab that leaves a sore arm. Contact was intentional, it caused pain or visible injury, and it stopped well short of creating a risk of death or permanent damage.
Penalties
Because third-degree assault and battery is a misdemeanor in most states, the maximum jail term is generally one year or less. Some states cap simple assault at six months; others go to a full year. Fines usually fall between $1,000 and $5,000, depending on the state and the facts.
Under federal law, which applies on federal property and military installations, simple assault carries up to six months in jail, while assault by striking or wounding carries up to one year.3Office of the Law Revision Counsel. 18 USC 113 – Assaults Within Maritime and Territorial Jurisdiction These federal categories track what most states call third-degree offenses.
Jail and fines are not the whole sentence. Common add-ons include:
- Probation, often in place of or on top of jail for first-time offenders, with conditions that can include anger management, substance abuse counseling, community service, and check-ins with a probation officer.
- Restitution for the victim’s documented out-of-pocket losses, such as medical bills and lost wages. Restitution does not cover pain and suffering, which belongs in a civil case.4U.S. Department of Justice. Restitution Process
- No-contact orders prohibiting communication with the victim during probation or longer.
When the Charge Involves a Domestic Relationship
The same conduct that produces a straightforward third-degree charge between strangers carries harsher consequences when the parties are family members, romantic partners, or members of the same household. Most states enhance penalties for assault and battery committed in these relationships even when the injury is minor. Enhancements often include mandatory intervention programs, longer probation, and no-contact orders.
There is one federal consequence worth flagging because it surprises people. A misdemeanor conviction for a crime of domestic violence triggers a firearms ban under 18 U.S.C. § 922, prohibiting the person from possessing or purchasing firearms or ammunition.5Office of the Law Revision Counsel. 18 USC 922 – Unlawful Acts The ban is permanent unless the conviction is expunged or set aside. A “minor” charge can produce a lifetime consequence most defendants never see coming.
Defenses
Several defenses can apply to a third-degree charge, and the right one can be the difference between conviction and dismissal.
- Self-defense. The most common defense. You must show that you reasonably believed you faced an imminent physical threat and that the force you used was proportional. It fails if you started the confrontation or used far more force than the situation called for.
- Defense of others. Similar to self-defense, but you were protecting a third person. Most jurisdictions allow it as long as it reasonably appeared the person you were protecting had the right to defend themselves.
- Consent. If the alleged victim agreed to the contact — as in a boxing match or a football game — there may be no battery. Consent has limits, and it generally will not cover contact that goes well beyond the rules of the activity.
- Lack of intent. If contact was genuinely accidental with no recklessness or negligence, the mental state element fails. Bumping into someone on a crowded sidewalk is not assault, even if they fall.
Self-defense claims are fact-intensive. Juries look at who started it, whether retreat was possible, and whether the response matched the threat. Answering a shove with a weapon is a much harder self-defense case than answering open hands with open hands.
Life After a Conviction
The sentence a judge hands down is only part of what a conviction costs. A third-degree assault or battery conviction creates a criminal record that shows up in places the courtroom never mentioned.
Employment
Most employers run background checks, and criminal convictions have no time limit on reporting for employment or tenant screening.6Federal Trade Commission. Tenant Background Checks and Your Rights The EEOC advises employers to weigh the seriousness of the offense, the time that has passed, and the job’s relevance rather than reject applicants automatically.7U.S. Equal Employment Opportunity Commission. Arrest and Conviction Records: Resources for Job Seekers, Workers and Employers In practice, a violence-related conviction can still block roles involving vulnerable populations, customer contact, or any employer with a blanket policy against hiring people with records. “Ban the box” laws in some states and cities push the criminal history question later in the hiring process, but they do not prevent it.
Housing
Landlords routinely screen for criminal history. Unlike some negative items that fall off credit reports after seven years, criminal convictions have no expiration under the Fair Credit Reporting Act. A misdemeanor assault conviction from a decade ago can still surface on a rental screening report.
Professional Licensing
Licensed professionals in healthcare, education, law, and other regulated fields face a separate layer of risk. State licensing boards typically require disclosure of criminal convictions and can deny, suspend, or revoke a license based on an assault or battery conviction. Any conviction involving violence draws scrutiny.
Expungement
Many states allow misdemeanor convictions to be expunged or sealed after a waiting period, provided the person has completed the sentence and stayed out of trouble. Policies vary widely. Some states offer automatic sealing for qualifying offenses; others require a petition and a hearing. Waiting periods run from one year to several. If expungement is granted, the conviction is removed from public background check databases, which can meaningfully reduce the housing and employment barriers above.
How Long Prosecutors Have to File
The state does not have unlimited time to bring a third-degree charge. Every state sets its own deadline, and the clock generally starts on the date of the offense. For misdemeanors, filing deadlines commonly fall between one and three years. If the suspect leaves the state or actively conceals their involvement, most jurisdictions pause the clock until the person returns or the concealment ends. Once the deadline passes, the prosecution cannot bring the charge regardless of the evidence.
