Sign the surrender express and write the name of the surrender person. According to the relevant information, the application for surrender needs to specify the reason and time of surrender, the seal of the insured unit and the personal signature. Surrender is to cancel the insurance policy. After the insurance contract is signed, both parties may terminate the contract through agreement or according to national laws. In most forms of non-life insurance term policies, there is generally a policy cancellation clause, which explains the conditions for either party to cancel the policy before the expiration, so as to safeguard their respective interests from unreasonable damage due to the termination of the insurance contract.
