guidelines but I have received a few raises since we have divorced two years ago. At the same time, he has gotten fired from jobs and doesn't even work full time and makes less than he did when we were married. I just got promoted again as my ex wants to again reopen child support saying I should be paying more because I make more. We share custody of our kids and they live with me half the time. I don't have an issue paying for children but it seems a bit much too readjust support every time i get a raise. Does it always have to be reopened?
