a friend of mine is in process of divorce, he found out that his wives and his baby, or rather the baby that he thought was his, is not really his. If he asks for paternity testing and it comes out that it is not his child, will he still have to pay child suport? they have been seperated for a long time already, however he has finally convinced her to file for divorce as she would not before this. He cannot afford to, and she is living with who we belive to be the child's real father. This is why he was asking her to file. We just want to know how this works in the state of wisconsin.
