Va. Code Ann. § 63.2-1911

Whenever a local department approves an application for public assistance on behalf of a child or children and it appears to the satisfaction of the local department that the child has been abandoned by the noncustodial parent or that the person who has a responsibility for the care, support, or maintenance of such child has failed or neglected to give proper care or support to such child, the local department shall refer the matter to the Division within the Department responsible for the enforcement of support. The foregoing provisions of this section shall not apply to applications for the Child Care Subsidy Program.
