Legal and medical questions pose a real hazard for librarians, because we have to avoid "Unauthorized practice of law" in most states. But we can suggest places for folks to look, such as the state law and other Massachusetts sites noted in the earlier answers to this CORI question. Though they are no doubt heavily burdened by the present economic situation, it still might be worth looking into the Office of Labor and Workforce Development to find websites or local offices that could help advise you how to deal with these records.
