Iowa Code § 232.1

This chapter shall be liberally construed to the end that each child under the jurisdiction of the court shall receive, preferably in the child’s own home, the care, guidance and control that will best serve the child’s welfare and the best interest of the state. When a child is removed from the control of the child’s parents, the court shall secure for the child care as nearly as possible equivalent to that which should have been given by the parents.
