I live in Washington DC. My and I have been married almost four years. Back in May a woman left a message on his phone saying she was pregnant. I called the women in January and she is not stating that the baby is three months old. She has not filed for child support. My husband is claiming that of course he never has been with her. However to try and salvage our marriage he said he would do a paternity test to convince me. How would he legal go about establishing paternity for this baby? Yes I know this is show for me but honestly me and his mother want to know. He mother ask can he sue her for slander if it is not true because she believes him.
