I'm not sure this is exactly the law in the Boston area but I would surmise it is at least similar. You might consider seeing if you are eligible for legal advise from Greater Boston Legal Services (GBLS). GBLS serves low income families and individuals (earning up to 125% of the poverty level, $33,125 for a family of 4 in 2021, or up to 200% in limited circumstances.) You can call: 617-371-1234
