2. The premise of the guarantee is that I need to agree to the contents of the guarantee agreement. If I sign the guarantee agreement, without my signature or authorization, the guarantee agreement is invalid for me, and I don't need to bear legal responsibility.
general rules of civil law
Article 66 An act without agency, beyond agency or after termination of agency can only be ratified by the principal, who shall bear civil liability. If the act is not ratified, the actor shall bear civil liability. Knowing that another person has committed a civil act in his own name without denying it is regarded as consent.
If an agent fails to perform his duties and causes damage to the agent, he shall bear civil liability.
If an agent colludes with a third party and damages the interests of the principal, the agent and the third party shall bear joint liability.
If a third party knowingly commits a civil act with the actor without agency, exceeds the agency or terminates the agency, and thus causes damage, the third party and the actor shall be jointly and severally liable.
