Iowa Code § 234.41: Tort actions.

A foster parent licensed by the department stands in the same relationship to the foster parent’s minor foster child, for purposes of tort actions by or on behalf of the foster child against the foster parent, as a biological parent to the biological parent’s minor child who resides at home. This section does not apply to a foster parent whose malicious, willful and wanton conduct causes injury or damage to a foster child or exposes the foster child to a danger caused by violation of a statute or the rules of the department.
