It is difficult to answer your question based on the information provided. It sounds as if you have an attorney and that you went to court to determine support. If the order signed by the judge is not in keeping with the evidence submitted at trial, or is not in keeping with what the judge decided, then there needs to be a Motion filed for relief from that order. However, it is certainly unclear from the information you give exactly what happened. Your attorney certainly should be able to answer your question.
