Yesterday I went to court for child support here's the info in 1997 I met my now husband I was 6 months pregnant at the time. Well my sons biological father was not involved in his life because he was not given opportunity to do so because of my husband wanting to play the role of his ( my son) father as to why he volunteerily sign the declaration of paturnity on his own emissions well to move along 10 years later we are separated for 8 years and I have since filed for child support against him well my son is covered by his health insurance and the child support services caught up with him for monetary assistance he All of a sudden decided that he didn't know what he signed and doesn't want to pay . Well the Judge made the judgement for the declaration of paternity be set aside which meant he will not have to pay child support. My question is this How do I change my sons last name in this curcumstances ? I would like to ave my moms maiden name
