Depending on the specific situation, if the company is not authorized to act as an agent, the signed contract company will not ratify it and will not bear civil liability. Article 17 1 of the Civil Code stipulates: "If there is no agency right, the agency right is exceeded or the agency right is terminated, the principal will bear civil liability only after ratification by the principal. If the act is not ratified, the actor shall bear civil liability. I know that if someone else carries out a civil act in my own name without denying it, it is regarded as consent. "
