Apparent authority的意思为“表见代理权；表见授权”，指第三人根据其与被代理人的交易情况，或者被代理人明知而允许代理人为其实施行为，或者被代理人的行为表示代理人在其控制之下，从而合理地相信代理人所享有的授权。

为了更好的理解Apparent authority，以下是该词的英文释义：In the United States, the United Kingdom, Australia, Canada and South Africa, apparent authority (also called “ostensible authority”) relates to the doctrines of the law of agency. It is relevant particularly in corporate law and constitutional law. Apparent authority refers to a situation where a reasonable third party would understand that an agent had authority to act. This means a principal is bound by the agent's actions, even if the agent had no actual authority, whether express or implied. It raises an estoppel because the third party is given an assurance, which he relies on and would be inequitable for the principal to deny the authority given. Apparent authority can legally be found, even if actual authority has not been given.

如：

1.Unauthorized signature means a signature made without actual, implied or apparent authority. The term includes a forgery. 

“未经授权的签字”指未经实践授权、默示授权或表见授权而作出的签字。该术语包括假造。

2.The apparent authority of an agent is to be determined by the acts of the principal and not by the acts of the agent. 

代理人的表见代理权是本人的行为而不是代理人的行为决定的。
