I am engaged to a great man and have been for years, we let a friend of ours move in with us for a few months and it ended terribly. Now the friend is grasping at straws and trying to use anything to seek revenge... he is asking for a paternity test, obviously my fiance is on the birth certificate. I am wondering if I am denying him one can he take me to court and force one on me even tho my childs certificate is already signed?
