The Child Support Enforcement Office in Union, Missouri is a division of the Franklin County Prosecuting Attorney’s Office.  The Franklin County Child Support division receives cases from the state child support office to prosecute through the court system.  These cases include enforcement of an existing child support order, i.e. when there was a divorce decree that ordered child support to be paid, and the support is not being paid, or obtaining a paternity and child support order, i.e. a child is born out of wedlock.  The Child Support Enforcement Office does not handle the issues of visitation or custody.



Cases are initiated at the State office level.  We do not open cases at our office.  A custodial parent may open a child support case by contacting the appropriate district office for the county where the custodial parent resides.
