hello! Generally speaking, whether you buy insurance in other provinces or in the province, you need to personally sign the insurance application, otherwise it will affect the legal validity of the insurance contract. Of course, if you are a child under the age of 18, you can ask your guardian to sign it. In this case, you must apply for a supplementary signature. In order to avoid disputes and protect their legitimate rights and interests, both the insured and the insured who have not signed the application form should go to the insurance company in time to go through the formalities of supplementary signature so as to keep written evidence. In essence, supplementary signature is an after-the-fact ratification of the signature behavior of others, which has legal effect and is protected by law.
