Child support assessments are made based on a variety of formulae, and vary from state to state in the United States. According to one study 38% of Illinois "obligor" parents not paying child-support said they lacked the money to pay. 23% used non-payment to protest a lack of visitation rights. 69% complained of no accountability over the spending of their child support money, while 13% said they did not want their child or children and 12% denied parentage.
