Child support question - Is child support determined only on one full-time job or is it based on all income?

Child support is considered for all income-both yours and his. He is trying to scare you into not going to court. I had the same issue last year with my ex. In Utah we have a recovery services that collects support from the absent parent for a small fee but it is well worth it. My support is never late and if they find he is making more money they take him to court on my childrens and mine behalf
