In a personal injury or wrongful death action, the plaintiff must serve a statement of damages of the defendant. No additional fee is charged if served at the same time as the summons and complaint. If served separately from the summons and complaint, the fee is charged and the statement of damages is served in the same manner as a summons if the defendant has not appeared in the action or in the manner provided by CCP 1010 et seq. if the defendant has appeared in the action. (CCP 425.11)
