Final answer:
Joe and Jim, stepbrothers by marriage only, would not be considered family or household members under the abuse prevention law (MGL 209A).
Step-by-step explanation:
Under the abuse prevention law (MGL 209A), the definition of a family or household member includes people who are or were married to each other, people who are or were residing together, and people who have a child in common (whether or not they have ever married or lived together). Stepbrothers by marriage only, like Joe and Jim, would not be considered family or household members under the law.
