Child Support Services

The Division of Child Support Services is responsible for establishing and enforcing orders for child support. Our Mission: Children deserve the security of having their needs met. Parents are responsible for providing financial, medical and emotional support for their children. To achieve these goals, we establish and enforce child support orders, treating all parties with respect, and serve the community through outreach and education.

In accordance with the Federal Deficit Reduction Act of 2005 the Department of Child Support Services may assess a $25 Annual Service Fee for each case that has never received public assistance. This fee will be assessed every year on October 1 for each case in which at least $500 has been disbursed to the family in the prior Federal Fiscal Year (October 1 - September 30). The fee will be automatically deducted from the next payment(s) issued to the custodial party after October 1 until the fee has been recovered in full.
