Hello, the insurance contract, that is, the insurance policy, has been delivered to you, so the receipt is the only evidence to confirm whether you have personally received and signed it, so you must personally sign it. If the insurance salesman signed it for you, then I don't think the insurance salesman will bear any responsibility for you in the future. Therefore, the receipt signed on behalf of is invalid. You can ask him to bring you another receipt. You can confirm and sign it yourself. thank you
