Legal analysis: the power of attorney of our company belongs to the general entrustment contract. If the company authorizes someone or an organization to handle the company's affairs on its behalf, it needs the signature of the legal representative and the official seal of the company to take effect. If it is a power of attorney issued by the unit, it needs to be stamped with the official seal and signed by the legal representative to take effect. The official seal of an enterprise can represent the company's behavior. If the company sends a non-legal representative to sign the contract, the other party must provide the power of attorney given by the company to avoid disputes caused by unclear authorization.
