In an interstate case, the parents live in different states, but asking the DC Superior Court to exercise long-arm jurisdiction to decide the case either is not possible or is not the best option for proceeding.
If the child(ren)'s primary custodian lives in the District and the other parent lives elsewhere, CSSD can ask the other state's child support agency for help to establish parentage, child support, retroactive child support, medical support, and even to enforce an already established order.
When the child(ren)'s primary custodian lives in another state and the other parent lives in the District, CSSD cooperates with the custodial parent's state to proceed with the case in an effort to ensure that parentage is established and the children receive the support owed.
