I am in a lesbian relationship and we have a 4-year-old son who is biologically mine. He doesnt have a father and we want to do a formal guardianship so that he can be on my partners medical insurance and flight benefits. My mother has threatened to take custody of him just because of the situation, but cannot prove me unfit. Would she stand a better chance of getting him if my partner had legal guardianship? Would that hurt me?
