My son's father so far has never met or even asked to visit with his son. He just now was served paper like a month or two ago the day of court regarding paternity? He denied being the father and requested a DNA test to be done. Which the test proved he is my son' father. But he is still avoiding? His parents retained him a attorney, can he actually sign his parental right over and not have to pay child support. Even though I am a single mom who is received state assistance to help with his child?
