The law of agency governs the relationship that arises when one person, the agent, acts on behalf of another, the principal, creating a legal relationship with a third party. A central issue in this area of law is the scope of the agent’s authority, as this determines whether the principal will be bound by the agent's actions. This essay will explain three fundamental categories through which an agent can derive authority: express actual authority, implied actual authority, and apparent authority. Understanding these categories is essential for determining the rights and liabilities between the principal, the agent, and the third party.
Express Actual Authority
The most straightforward category of authority is express actual authority. This is authority that the principal has explicitly given to the agent. It arises from a consensual agreement between the principal and the agent, and its scope is determined by interpreting this agreement. The instructions may be given orally or in writing, with more formal arrangements, such as a power of attorney or a detailed employment contract, providing a written record of the agent's powers (Sealy and Hooley, 2020).
For example, if a homeowner (the principal) instructs an estate agent (the agent) in writing to "market my property for sale at a price of no less than £250,000", the agent has express actual authority to advertise the property and enter negotiations on those terms. The key element is the explicit statement from the principal defining what the agent is permitted to do. If the agent acts within the confines of these express instructions, the principal will be legally bound by the resulting contract with a third party. Conversely, if the agent disregards these instructions, for instance by agreeing to a sale for £240,000, they would be acting outside their express actual authority.
Implied Actual Authority
Implied actual authority is another form of genuine authority that arises from the consent of the principal, but it is inferred rather than explicitly stated. It covers the power to do things that are reasonably necessary to carry out the express instructions given by the principal. This can be sub-divided into two types: incidental authority and usual authority.
Incidental authority is the authority to do whatever is ordinarily or necessarily incidental to the effective execution of the express authority. For example, an agent instructed to sell a car would have implied incidental authority to allow a potential buyer to test drive it. Usual authority is the authority to do what is usual in a particular trade, profession, or business for an agent of that type. In Hely-Hutchinson v Brayhead Ltd [1968] 1 QB 549, a company chairman who had often acted as a de facto managing director without formal appointment was held to have implied actual authority to bind the company to a contract, as the board had acquiesced to his conduct over a long period. Lord Denning MR stated that authority was implied from "the conduct of the parties and the circumstances of the case". This demonstrates that the law will infer authority where the agent's position implies they have the power to perform certain acts customary for that role.
Apparent (or Ostensible) Authority
Apparent authority, also known as ostensible authority, is conceptually different from the first two categories. It is not actual authority because it is not based on an agreement between the principal and the agent. Instead, it is the authority that an agent appears to have from the perspective of a third party, based on a representation made by the principal. Its purpose is to protect third parties who rely in good faith on such appearances (Sealy and Hooley, 2020).
The classic requirements for establishing apparent authority were outlined in Freeman & Lockyer v Buckhurst Park Properties (Mangal) Ltd [1964] 2 QB 480. For a principal to be bound, there must be:
- A representation by the principal to the third party that the agent had authority.
- Reliance on that representation by the third party.
- An alteration of the third party's position as a result of that reliance.
The "representation" can be made through conduct, such as by permitting the agent to occupy a certain position or by allowing them to act in a particular way. For example, if a company allows an individual to use the title of "Sales Director" and provides them with a company car and office, it is representing to the outside world that this person has the authority normally associated with that role. If a third party relies on this representation to enter into a contract, the company (the principal) will be estopped, or prevented, from denying the agent's authority and will be bound by the contract, even if the agent was acting outside their actual authority.
In conclusion, the authority of an agent can be established in several ways. Express actual authority is granted explicitly, while implied actual authority is inferred from the agent's role or the necessity of their task. By contrast, apparent authority is not real authority but is created by a principal's representation to a third party, binding the principal to protect the third party's reliance. These three categories create a framework that balances the principal's intention to control the agency relationship with the need to provide commercial certainty for third parties.
