It is illegal to impersonate someone else's signature. If someone else pretends to be my signature without my knowledge, I won't ratify it, I won't bear legal responsibility, and the signatory will bear the responsibility. If it is approved, I should bear the responsibility. Signing on behalf of others is an agency act. If I don't know, I have no right to represent and I don't bear legal responsibility. However, if I know that someone else signed my name without denying it, or that I ratified it, the signature is binding on me and I should bear legal responsibility. Impersonating someone else's signature is an act of infringement of the right to name, perjury and so on. Selling fake star signatures constitutes the crime of obstructing testimony and bill fraud. Contracts signed in the course of litigation may constitute the crime of contract fraud, and other corresponding contracts may constitute the crime of financial fraud. Bear the consequences of the signed contract or other documents, and compensate the losses of the impersonator and signatory. The crime of fraud is the consequence of taking advantage of his position to impersonate his signature, and he also needs to bear legal responsibility.

The counterpart may urge the principal to ratify it within 30 days from the date of receiving the notice. If the trustor fails to declare it, it shall be deemed as refusal to ratify it. Before the act committed by the actor is ratified, the bona fide counterpart has the right to revoke it. Revocation shall be made by notice. If the act committed by the actor is not ratified, the bona fide counterpart has the right to demand the actor to perform the debt or demand the actor to compensate for the damage he has suffered. However, the scope of compensation shall not exceed the benefits that the counterpart can obtain when the principal ratifies. If the counterpart knows or should know that the actor has no right to act as an agent, the counterpart and the actor shall bear the responsibility according to their respective faults.
