Law of agency

The law of agency is an area of commercial law dealing with a set of contractual, quasi-contractual and non-contractual fiduciary relationships that involve a person, called the agent, who is authorized to act on behalf of another (called the principal) to create legal relations with a third party. It may be referred to as the equal relationship between a principal and an agent whereby the principal, expressly or implicitly, authorizes the agent to work under their control and on their behalf. The agent is, thus, required to negotiate on behalf of the principal or bring them and third parties into contractual relationship. This branch of law separates and regulates the relationships between:

The reciprocal rights and liabilities between a principal and an agent reflect commercial and legal realities. A business owner often relies on an employee or another person to conduct a business. In the case of a corporation, since a corporation can only act through natural person agents, the principal is bound by the contract entered into by the agent, so long as the agent performs within the scope of the agency.

A third party may rely in good faith on the representation by a person who identifies himself as an agent for another. It is not always cost effective to check whether someone who is represented as having the authority to act for another actually has such authority. If it is subsequently found that the alleged agent was acting without necessary authority, the agent will generally be held liable.

The role of an agent and scope of their authority affect how the agent is described. For example,

An agent who acts within the scope of authority conferred by their principal binds the principal in the obligations they create against third parties. There are essentially three kinds of authority recognized in the law: actual authority (whether express or implied), apparent authority, and ratified authority.

Actual authority can be of two kinds. Either the principal may have expressly conferred authority on the agent, or authority may be implied. Authority arises by consensual agreement, and whether it exists is a question of fact. An agent, as a general rule, is only entitled to indemnity from the principal if they have acted within the scope of their actual authority, and if they act outside of that authority they may be in breach of contract, and liable to a third party for breach of the implied warranty of authority.

Express actual authority means an agent has been expressly told they may act on behalf of a principal.

Implied actual authority, also called "usual authority", is authority an agent has by virtue of being reasonably necessary to carry out his express authority. As such, it can be inferred by virtue of a position held by an agent. For example, partners have authority to bind the other partners in the firm, their liability being joint and several, and in a corporation, all executives and senior employees with decision-making authority by virtue of their position have authority to bind the corporation. Other forms of implied actual authority include customary authority. This is where customs of a trade imply the agent to have certain powers. In wool buying industries it is customary for traders to purchase in their own names. Also incidental authority, where an agent is supposed to have any authority to complete other tasks which are necessary and incidental to completing the express actual authority. This must be no more than necessary
