Assault and Battery in Massachusetts: Charges and Consequences

Assault and battery penalties in Massachusetts range from a misdemeanor punishable by up to two and a half years in a house of correction and a $1,000 fine to a felony punishable by up to 15 years in state prison when a dangerous weapon causes serious bodily injury. The state treats assault (a threat or attempt to harm) and battery (actual harmful contact) as distinct offenses, and the sentence a court can impose depends on who was harmed, how, and whether the defendant has qualifying priors.

Assault and Battery Are Two Different Things

Neither offense is defined by statute. Massachusetts courts have built the definitions through common law, and the assault and battery statute prescribes penalties without spelling out the elements.¹

Assault happens in one of two ways: an attempted battery (you swing and miss) or a threatened battery (menacing conduct that causes someone to fear immediate harm).² Battery is the intentional and unjustified use of force against another person. Any unwanted physical contact qualifies, however slight. A shove, a slap, spitting. The contact must be intentional, but you do not need to intend serious harm.

Simple Assault and Battery

The baseline charge under Chapter 265, Section 13A(a) is a misdemeanor. The maximum penalty is two and a half years in a house of correction or a fine of up to $1,000.¹ Courts can also impose probation, community service, or anger management as sentencing conditions.

Misdemeanor here does not mean minor. A conviction goes on your criminal record, shows up on background checks, and can cost you a professional license.

Assault and Battery Causing Serious Bodily Injury

Section 13A(b) turns the offense into a felony in three situations:

The victim suffers serious bodily injury, meaning permanent disfigurement, loss or impairment of a bodily function or limb, or an injury creating a substantial risk of death.
The defendant knew or had reason to know the victim was pregnant.
The defendant knew a temporary or permanent restraining, vacate, or no-contact order was in effect against them.

Each of these carries up to five years in state prison, or up to two and a half years in a house of correction, a fine of up to $5,000, or both prison and a fine.¹

Assault and Battery With a Dangerous Weapon

Using a weapon triggers a separate statute, Chapter 265, Section 15A, and much steeper penalties. A dangerous weapon includes firearms and knives, and Massachusetts courts have also applied the term to ordinary objects used in a way capable of causing serious harm or death, including a baseball bat, a car, and a shod foot.

Penalties scale by circumstance:

General offense under Section 15A(b): up to 10 years in state prison, or up to two and a half years in a house of correction, a fine of up to $5,000, or both.
Victim age 60 or older under Section 15A(a): up to 10 years in state prison. A second or subsequent conviction carries a mandatory minimum of two years, with no probation, parole, or early release.
Serious bodily injury, pregnant victim, or violation of a restraining order under Section 15A(c): up to 15 years in state prison, or up to two and a half years in a house of correction, a fine of up to $10,000, or both. This subsection also covers an adult who uses a dangerous weapon against a child under 14.

All are felonies.³

Domestic Assault and Battery

Chapter 265, Section 13M covers assault and battery against a family or household member. The category includes a current or former spouse, someone with whom the defendant shares a child, or someone in a current or former substantive dating or engagement relationship. Courts weigh the length of the relationship, its nature, frequency of contact, and how long ago it ended when deciding whether a dating relationship qualifies as substantive.⁴

A first offense is punishable by up to two and a half years in a house of correction, a fine of up to $5,000, or both. A second or subsequent conviction raises the maximum to five years in state prison.⁴

For any Section 13M conviction, or even a continuance without a finding, the court must order the defendant to complete a certified batterer’s intervention program unless the judge makes specific written findings that the program is unnecessary or the program itself determines the defendant is unsuitable.

Federal law then adds a lifetime firearm ban. Anyone convicted of a misdemeanor crime of domestic violence is permanently prohibited from possessing a firearm or ammunition.⁵ The ban has no expiration and no waiver.

Assaults on Police Officers and Public Employees

Chapter 265, Section 13D covers attacks on public employees, public transit workers, and contracted transit operators, and reserves the harshest penalties for assaults on police officers. Several of these carry mandatory minimums, meaning a judge cannot suspend the sentence or substitute probation:

Assault on a public employee or transit worker on duty: mandatory minimum of 90 days, maximum of two and a half years in a house of correction, and a fine between $500 and $5,000, or both.
Attempting to disarm a police officer on duty: up to 10 years in state prison, or up to two and a half years in a house of correction, plus a fine of up to $1,000.
Causing serious bodily injury to a police officer on duty: mandatory minimum of one year and maximum of 10 years in state prison, or one to two and a half years in a house of correction. A $500 to $10,000 fine may be added but cannot replace the prison term. The sentence cannot be suspended, reduced, or filed, and the defendant is ineligible for probation, parole, work release, furlough, or good conduct deductions.

The statute also authorizes warrantless arrest on probable cause when the victim is a transit worker assaulted while operating a vehicle.⁶

Repeat Offender Enhancements

Prior convictions can override the ordinary sentencing range. Chapter 279, Section 25 sets up two tracks.

The general habitual criminal provision applies to anyone convicted of a felony who has two prior felony convictions that each resulted in a state or federal prison sentence of at least three years. A defendant who meets that threshold must receive the maximum sentence allowed for the current offense.⁷

The second track is narrower and harsher. It lists qualifying violent and sexual offenses from Chapter 265, including assault and battery causing serious bodily injury and assault and battery with a dangerous weapon. If the defendant has two prior qualifying convictions with sentences of at least three years each, and the current offense is also a qualifying crime, the court must impose the statutory maximum with no possibility of reduction, suspension, probation, parole, work release, furlough, or good conduct credit.⁸ Juvenile adjudications do not count toward the two-prior requirement.

Consequences Beyond the Sentence

The statutory penalty is only part of what a conviction costs.

Criminal Record

Every conviction appears on your Criminal Offender Record Information (CORI), which Massachusetts employers, landlords, and licensing boards can access. A misdemeanor conviction becomes eligible for sealing three years after the date of conviction or release from incarceration, whichever is later. A felony requires a seven-year wait. Sealing is not automatic; you must petition the Massachusetts Probation Service, and sealed records remain accessible to law enforcement and certain government agencies.⁹

Firearms

A violent crime conviction makes obtaining a Massachusetts license to carry or firearms identification card very difficult. The federal domestic-violence firearm ban, described above, is permanent and applies nationwide.⁵

Immigration

For non-citizens, an assault or battery conviction can lead to deportation, denial of visa renewal, or permanent inadmissibility. Federal immigration law treats offenses involving intentional harmful conduct as potential crimes involving moral turpitude, and aggravated felony convictions under federal immigration definitions can trigger mandatory removal with almost no relief. Federal categories do not track Massachusetts categories, so a charge that looks minor under state law can carry severe immigration consequences.

Civil Liability

A victim can sue for damages regardless of what happens in the criminal case. Civil claims use a preponderance-of-the-evidence standard rather than proof beyond a reasonable doubt, so a defendant who wins the criminal case can still lose the civil one. Damages can cover medical expenses, lost income, pain and suffering, and compensation for scarring or disfigurement.
