In April 1998, the District of Columbia Child Support Program was transferred from the Department of Human Services to the Office of the Corporation Counsel, now the Office of the Attorney General (OAG). This act merged the administrative and legal functions of the program. Accordingly, OAG is the authorized IV-D agency for the District of Columbia.

The Child Support Services Division (CSSD), authorized under Title IV-D (hereinafter, IV-D) of the Social Security Act, provides services to assist families by locating absent parents, establishing paternity, establishing monetary and medical support orders, collecting ongoing support and enforcing delinquent support orders.  The program helps many families transition from TANF and keeps other families from needing to seek public assistance to all.  In addition, the program collects payments directly from non-custodial parents (NCPs), as well as from NCPs through their employers and other states' government entities.  CSSD also disburses payments to custodial parents (CPs) in the District and in other states, recoups welfare – Temporary Assistance to Needy Families (TANF) – payments and Medicaid paid to or for families, and recoups foster care costs for children. 

The District’s IV-D Program has approximately 198 authorized full-time employees (FTEs) and, of that number, three positions vacant at the beginning of 2009. For fiscal year 2008, the program also reports 63,203 cases, representing about 67,695 children younger than 18 years old. There are 17,599 current TANF cases, 27,367 former TANF cases, and 18,237 never TANF cases. Like so many states across the country, the CSSD caseload has shifted substantially so that now a majority of customers have either moved off of TANF or were never on TANF.
