My wife wants a divorce. Last June she told me she does not love me any more. I have tried everything I know to do to fix it but she is determined determined to get a divorce. I live in Louisiana and want to know if we have joint custody do I have to pay child support and if so how much? 3 Children, The wife makes about 1600.00 A month I make about 4000.00 a month.

Depends on what kind of joint custody. There is joint legal custody and joint physical custody. Joint legal means you both have to make the decisions. It has nothing to do with visitation. Joint physical custody, you may end up owing some support since you make more than she does.
