My husband found out today that his job has to fill out paper work for child support the thing about it is that the child is 12 we live in TX and she lives in AZ. He is not on the birth cert nor never seen the child nor has he taken a DNA test. If he gives up his rights will he still have to pay child support even if he has 3 children of his own with me? He got served with papers back in 2003 but it never went through.
