Legal analysis: the contract is forged by others and can be reported to the police. Impersonation signature belongs to unauthorized agency behavior, and it will take legal effect only after being ratified by the principal. Unauthorized agency refers to the implementation of civil acts in the name of others without authorization, legal basis or designation by people's courts or designated units. A contract with forged signature is invalid. If it has the purpose of illegal possession and the amount is large, it is suspected of contract fraud.

Legal basis: Article 148 of the Civil Code of People's Republic of China (PRC) * * * Where a party commits a civil legal act that makes his will express against his true meaning by fraudulent means, the defrauded party has the right to request the people's court or an arbitration institution to cancel it.
