Legal Analysis

1. According to the authorization of the authorizer, signing on behalf of the authorizer is a legal act. This phenomenon is very common in real life. Some are trivial matters in daily life, and some are major economic activities and important matters, which are authorized by the principal to be signed by others. For example, it is normal for the principal to hand over his or her ID card and authorization letter to the principal to pick up the express or even sign the contract. 2. Without the entrustment and authorization of the principal, it is illegal to sign on behalf of others without permission. In serious cases, you may also be held criminally responsible. For example, if a national civil servant signs an important request for instructions without the consent, approval, or authorization of the person with the authority to handle it, resulting in significant economic losses or casualties, he will be held criminally responsible. Agents include principal agents and legal agents. Whoever defrauds the other party of property during the process of signing and performing a contract for the purpose of illegal possession, and the amount is relatively large, shall be sentenced to fixed-term imprisonment of not more than three years or criminal detention, and shall also or solely be fined.
