DCSS is Delaware's IV-D agency, run as a single state division rather than independent county agencies, though customer service lines are organized by county — New Castle, Kent, and Sussex each have their own number.
The division locates noncustodial parents, establishes paternity, sets support orders, and collects and enforces payments once a case is active, with case management available through Delaware's my.delaware.gov portal.

How to Apply for Child Support in Delaware
A parent or caretaker of a child can apply for Delaware child support services through the my.delaware.gov portal or by calling the customer service line for their county. Families already receiving TANF or Medicaid in Delaware are typically referred for services automatically.
The application requires identifying information for both parents and the child, along with any existing custody or support paperwork. DCSS then works to establish paternity if needed and get a support order in place.
How to Collect Child Support Payments in Delaware
Delaware collects most support through income withholding once an order is active, disbursed to the receiving parent by direct deposit or debit card.
Payments can be tracked online through the iPayOnline portal, which shows payment history and current balances for both parents in a case.
Missed Payments & Enforcement
DCSS's enforcement measures include intercepting tax refunds, suspending licenses, and reporting arrears to credit bureaus when a parent falls behind on payments.
As in every state, federal law allows a passport to be denied or revoked once past-due support exceeds $2,500. Delaware's enforcement measures page has the current list of tools in active use.
