Close a Case

Child Support Services (CSS) will close a case:

Step 1.When an obligation ends and the non-custodial parent has paid all support and arrears, or

Step 2.When making all possible reasonable attempts to establish or enforce an order with no success, or

Step 3.When trying but not being able to find the non-custodial parent or the custodial party, or

Step 4.When a written closure notice is provided by the person who applied for services

CSS may send a letter to you 60 days before closing the case. Even if a case is closed, it does not always mean that the non-custodial parent's legal duty to pay support will end. If new information about a case is received, the case may be reopened.
