D.C. Mun. Regs. tit. 29, r. 29-1702
The Department shall use all available means for enforcement of child support orders when the applicant is a recipient of public assistance. In non-public assistance cases, a caretaker or custodian may request assistance from the Department for enforcement of child support orders by means other than, or in addition to, income withholding.
When assistance has been requested, or when a case is being enforced under Part D of Title 4 of the Social Security Act, and the Department identifies real or personal property of a responsible relative upon which a lien may be asserted, it shall refer the matter to the Office of the Corporation Counsel for review and appropriate action.
In every support case in which assistance is requested or which is being enforced under Part D of Title 4 of the Social Security Act, the Department shall, in addition to using other available means, refer the matter to the Department of Finance and Revenue for interception of the income tax refund of individuals who owe overdue support.
