If the individual knows the contents of the insurance contract and intends to authorize the salesman to sign it on his behalf, the insurance contract is valid in this case. If the salesman signs the insurance contract without the knowledge of the customer, the insurance contract is invalid.

As an insurance salesperson, you are not allowed to sign for customers during the exhibition period. It is illegal for business personnel to sign for customers. If they sign without the customer's consent, they will bear corresponding legal responsibilities for illegal acts.

But as long as the customer agrees, the insurance company will generally not pursue it. After all, insurance companies first have management loopholes.

Extended data:

Whether to surrender in full depends on the collection of evidence. If it can be proved that I didn't sign it, it can be settled by agreement or by bringing a lawsuit to the court. However, insurance companies act in accordance with the contract.

If the minor is the insured, it needs the signature of the insured, that is, the adult, which is recognized in the insurance law.

If the insured is an adult, it needs to be signed by himself for confirmation, otherwise it can be considered as a partially invalid contract.
