California parents are civilly liable for a “minor’s acts of willful misconduct resulting in death, personal injury or property damage.” See Cal. Civ. Code § 1714.1 (2005). Specifically,
Any act of willful misconduct of a minor which results in injury or death to another person or in any injury to the property of another shall be imputed to the parent or guardian having custody and control of the minor for all purposes of civil damages, and the parent or guardian having custody and control shall be jointly and severally liable with the minor for any damages resulting from the willful misconduct.
Subject to the provisions of subdivision (c), the joint and several liability of the parent or guardian having custody and control of a minor under this subdivision shall not exceed twenty-five thousand dollars ($ 25,000) for each tort of the minor, and in the case of injury to a person, imputed liability shall be further limited to medical, dental and hospital expenses incurred by the injured person, not to exceed twenty-five thousand dollars ($ 25,000). The liability imposed by this section is in addition to any liability now imposed by law.
