The Utah Domestic Support Obligation Questionnaire (DSO) is a form used in the state of Utah to assess a person's financial obligations for the support of a minor child or children. It is a comprehensive form that requires detailed information about the incomes and expenses of both parents, and any other financial obligations that may affect the child or children's support. The DSO is completed by both parties in the child support case and submitted to a court or other state agency for review. There are two types of Does: the original DSO, and the modified DSO. The original DSO is used for initial child support determination, while the modified DSO is used for modifications or adjustments of existing child support orders. The DSO is used to calculate the amount of child support a parent may be required to pay.
