Effective. If you sign a contract with a third party in the name of the principal, you can sign the principal's name, your own name, or both. According to the regulations, civil subjects can carry out civil legal acts through agents. In accordance with the provisions of the law, the agreement of the parties or the nature of civil legal acts, civil legal acts that should be implemented by themselves shall not be represented.

The other party can prove that I signed the fake name, and this contract is valid; If you sign a fake name for someone else, the contract is invalid. It is fraudulent to sign a contract without using your real name. According to the relevant laws and regulations, if one party uses fraudulent means to make the other party conclude a contract against its true meaning, the injured party has the right to request the people's court or arbitration institution to change or cancel it. If the signed pseudonym does not match the household registration, but belongs to other names used to express the meaning of the actor in daily activities, if the signing behavior is the expression of the actor's true meaning and does not make the other party violate the true meaning, the signed contract shall be a valid contract agreed by both parties. If the actor signs his name on the premise that it may harm the interests of others, so that the other party violates his true meaning without knowing it, the effectiveness of the actor's signature behavior is to be determined, and the contract can be revoked or changed. The legal consequences arising from the contract concluded by the entrusted agent shall be borne by the principal. However, contracts involving personal nature in adoption agreements, divorce agreements and bequest and maintenance agreements must be handled by the parties themselves and cannot be signed by others. To sum up, whether a contract that is not signed by me is invalid depends on whether the parties have explicitly authorized their signers to sign it on their behalf. Such a situation will be considered invalid in law if it is signed without the express authorization of the parties.
