Agent for undisclosed or partially disclosed principal: An agent need not inform the person with whom he is negotiating that he is acting on behalf of a principal. The secret principal is usually called an “undisclosed principal.” oOr the agent may tell the other person that he is acting as an agent but not disclose the principal’s name, in which event the principal is “partially disclosed.” Lack of authority in agent: An agent who purports to make a contract on behalf of a principal, but who in fact has no authority to do so, is liable to the other party. Agent acting on own accord: An agent will be liable on contracts made in a personal capacity. Termination of agency: The agency relationship can terminate either by action of the parties or by law. By act of parties: The agency agreement may be terminated either expressly or implicitly. oExpress termination: Many agreements contain specified circumstances whose occurrence signals the end of the agency (expiration of a fixed period of time). An agreement may also terminate on the accomplishment of a specified act or following a specific event. Mutual consent between the parties will end the agency. Moreover, the principal may revoke the agency or the agent may renounce it; such a revocation or renunciation of agencywould be an express termination. oImplied termination: There are a number of other circumstances that will spell the end of the relationship by implication.
