My husband's ex wife had child in NC while she was still legally married to my husband. His name is now on the child's birth certificate because she was still married to him. He didn't know anything about this until recently now that she is trying to put the child's biological father on child support. To my knowledge, NC law states that the husband goes on a birth certificate even if he's not the father. She contacted child support in NC and said she was told that the father on the certificate must take a paternity test to be removed before they can go after the biological father. Is this correct? Secondly she is having the child support case sent to Louisiana because that's where she think my husband is located, and she said Louisiana child support law says that my husband will be responsible for not only the child whose birth certificate he's on but also her other child. The biological father of the second child is the same man for the first child. He signed an affidavit since they was not married with the second child to have his name put on the birth certificate. The confusing part to me is how will my husband be responsible for a child/children that is not his, and why should he take a paternity test if the biological father is coming forward saying that both kids are his? Can her and the kids biological father get this matter taken care of on their own without involving my husband? Can each party sign an affidavit acknowledging that my husband is not the father and have the biological father state that he is the father?
