My partner and I used a friend to concieve a baby.. the friend and I did it the old fashion way bc we figured it would work better, anyways now that our son was born he has changed his mind and is fighting for custody, we have a lawyer and understand he is going to have his rights, but another friend mentioned maybe he would agree to a THREE WAY custody.. I was just wondering what that was and what that would mean for my partner, what rights would she have?
