If the signer uses another person's signature without authorization, the fraudulent person shall bear the contract liability.
It's against my will if you sign the contract yourself without a power of attorney. You can bring your own non-signature certificate (explanation) and the original ID card to communicate with the signatory to terminate the contract.
Article 66 of the General Principles of Civil Law states that if an agent has no power of agency, exceeds the power of agency or terminates the power of agency, the principal will bear civil liability only after ratification by the principal. If the act is not ratified, the actor shall bear civil liability. Knowing that someone else has committed a civil act in my name without denying it is regarded as consent.
