What Is Assault and Battery in Massachusetts?

In Massachusetts, Assault and Battery is a serious offense that involves either intentional physical contact or an attempt to cause harm. According to Massachusetts General Laws Chapter 265, Section 13A, Assault and Battery can occur in two forms:

  • Harmful Battery: The deliberate and unlawful use of force on another person.
  • Offensive Battery: Unwanted physical contact that does not necessarily cause harm but is offensive or disrespectful.


Depending on the severity of the alleged offence and whether there are any aggravating circumstances, assault and battery carry the following penalties:

  • Use of a dangerous weapon
  • Serious bodily injury
  • Victim being a public employee, elderly, pregnant, or disabled


In Massachusetts, even a first-time conviction can result in jail time, fines, probation, or mandatory anger management programs. More serious charges like Aggravated Assault and Battery may lead to years of imprisonment.

I was fortunate enough to come across Matthew Peterson Law via word of mouth and incredibly positive reviews. And if I could give 10,000 stars I would. I was assisted by Attorney Margaret Petersen, who is an excellent, incredibly knowledgeable, compassionate, and diligent professional. The individuals at Matthew Peterson Law are top notch and I cannot say enough positive words about them.

I am an attorney and a registered nurse, and I hold professionals to a high standard. Matthew Peterson exceeded every one of them. I retained him seven days before a contested 209A restraining order hearing — from out of state, with a record thousands of pages deep and an active case in another jurisdiction layered on top. Seven days is not much time. He made it look like plenty. He read everything; I know because within a day his questions were sharper than mine. He built the strategy, moved fast, and kept me informed in plain English at every step. His entire office works the same way — I sent materials at one in the morning and had a substantive reply before lunch. Not once did I wonder where my case stood. In the courtroom he was everything you want: prepared, precise, composed, and completely in command of the record. The order was dismissed at the return hearing. What set him apart was not just skill — it was judgment and decency. He understood what was actually at stake for my family and treated it with the seriousness it deserved, without ever losing his calm. He told me the truth, including when it was hard, and then he delivered. If you need a restraining order defense attorney in Massachusetts, hire Matthew Peterson. I say that as a client and as a fellow lawyer: he was everything I could have asked for, and more. Five stars is the ceiling on this form. He earned more.

I will recommend this Law Firm to anyone who wants their case be treated with the utmost attention needed. This office delivered on their promise. Thank you, Prince

I had the pleasure of getting Attorney Manchinton to represent me at a Clerks Magistrate Hearing. I believe that helped turn this situation into a positive experience for myself. I believe without his help it would have been much more stressful. I thank him and all those at the office that helped too!
