Perhaps you are referring to DYFS? DYFS, or the Division of Youth and Family Services, is, according to their website (http://www.state.nj.us/dcf/divisions/dyfs/), "New Jersey's child protection and child welfare agency within the Department of Children and Families. Its mission is to ensure the safety, permanency and well-being of children and to support families.
DYFS is responsible for investigating allegations of child abuse and neglect and, if necessary, arranging for the child's protection and the family's treatment."
