In principle, it must be signed by myself. Because if it is not signed by the applicant and the insured himself, the insurance contract may not take effect, and the insurance company may refuse to pay compensation on this ground when the insurance accident occurs.

If the insured is a minor and the beneficiary is the guardian of the insured, he may sign on behalf of the insured, but he cannot sign on behalf of the insured.

I didn't sign the agreement, whether it has legal effect depends on the specific situation:

1. If your agent signs for you within the scope of authority of the agent; Or you know that someone else signed the cooperation agreement in your name without denying it, then the signature is valid and the cooperation agreement is valid.

2. If someone else signs on your behalf without authorization, beyond the scope of authorization or after the authorization is terminated, the signature of the agent is valid and the cooperation agreement is valid after your ratification.

3. If it doesn't belong to the above situation, the signed cooperation agreement is invalid and has no legal binding force on you.
