Never let anyone else sign it! Especially when the insurance salesman tells you that you can sign on your behalf, you should be more careful. Because the act of signing insurance on behalf of the insurance company may eventually have two consequences: First, if you later find yourself cheated into buying insurance and want to surrender the insurance in full on the grounds of signing insurance on behalf of the insurance company, the insurance company will use the Supreme Judicial Interpretation 2 to emphasize that the act of signing insurance on behalf of the insurance company is effective. Secondly, in case of an accident, you ask the insurance company for compensation, and the insurance company will "sign" the insurance contract, so the contract is invalid and refuses to pay compensation. In short, there are many sequelae caused by proxy signature.
In insurance practice, agent signature is often closely related to the misleading behavior of insurance salesmen. For example, in order to facilitate the contract as soon as possible and get the commission, the salesman of the insurance company will conceal the important contract information related to the signature and let the person who should not sign it sign it, thus misleading. More cases can go to the professional insurance website-Century Insurance. There are many cases of such sales fraud.
