This is stipulated in the Civil Procedure Law for the Disabled and the Evidence Regulations of the Supreme Court. Both parties negotiate to select the appraisal institution. If negotiation fails, the court shall designate an authentication institution. What is popular now is that negotiation fails, and the court draws lots to determine the appraisal institution. Not going will not affect the selection and entrustment of appraisal institutions. The insurance company has no right to disagree with the court's choice, and the court will clearly define the liability for compensation in the judgment. When to carry out the appraisal, the appraisal institution shall make a decision after receiving the entrustment, whether to issue an appraisal opinion or temporarily suspend the appraisal, and then reply to the appraisal when the time is ripe. The compensation standard is determined according to the appraisal conclusion.
