4.4 Principles of Agency

What Is Agency?

Agency is a legal relationship in which one party (the agent) is authorised to act on behalf of another party (the principal) to create legal relations between the principal and a third party. When an agent acts within authority, the legal consequences fall on the principal, not on the agent: the principal is bound to the third party and acquires rights against the third party, just as if the principal had acted personally.

Agency is fundamental to insurance. Insurers sell through brokers, tied agents, appointed representatives, comparison websites, and their own staff. Almost every insurance transaction involves an agent of some kind, so the law of agency decides who is bound by what was said, known, or done during the sale.

Quick Answer: The single most important agency question in IF1 is "whose agent is this person?" An insurance broker is generally the agent of the insured; a tied agent, appointed representative, or the insurer's own sales staff is the agent of the insurer. That distinction determines who is bound by the agent's knowledge and acts.

Creation of Agency

An agency relationship can arise in four ways.

1. By Express Agreement

The principal and agent expressly agree, orally or in writing, that the agent will act for the principal. A formal agency agreement between an insurer and a broker or appointed representative is the clearest example.

2. By Implied Conduct or Ratification

• Implied agency arises from the parties' conduct or the circumstances — for example, an employee who habitually negotiates contracts of a particular kind for the employer.
• Ratification occurs when a person (the principal) later approves an act that an agent did without authority. Ratification retrospectively makes the act binding on the principal as if it had been authorised from the outset. The principal must have been in existence at the time of the act, must know the material facts, and must ratify within a reasonable time.

3. By Estoppel (Apparent or Ostensible Authority)

If the principal, by words or conduct, represents to a third party that a person has authority to act on the principal's behalf, and the third party relies on that representation, the principal is estopped (prevented) from denying the agent's authority. This is agency by estoppel, and it is the basis of apparent (ostensible) authority.

4. By Necessity

Agency of necessity arises in an emergency where a person takes action to preserve or protect another's property when the owner cannot be contacted (for example, a carrier arranging emergency repairs to perishable goods). The requirements are strict: a genuine emergency, impossibility of communication, and action that is reasonable and in the owner's interest.

Types of Authority

The legal effect of an agent's act depends on the type of authority the agent possessed.

Actual Authority

Actual authority is what the principal has actually authorised the agent to do, whether expressly (in writing or by oral instruction) or by implication from the role the agent occupies. An insurance broker given binding authority to place risks up to a stated limit has actual authority up to that limit.

Apparent (Ostensible) Authority

Apparent authority (also called ostensible authority) depends not on what the agent was actually told but on what the principal represented to the third party. If an insurer allows an agent to hold itself out as the insurer's representative, the insurer can be bound by the agent's acts within the apparent scope of that representation, even if the agent exceeded actual instructions. The third party must act in good faith and without notice of the limitation.

Exceeding Authority and Ratification

If an agent acts outside both actual and apparent authority, the principal is not bound. The principal may, however, ratify the unauthorised act, after which it is treated as authorised from the outset. If the principal does not ratify, the agent may be personally liable to the third party for breach of warranty of authority (see Section 4.5).

Broker vs Agent in Insurance

This is the most heavily tested agency distinction in IF1. The words "broker" and "agent" have specific legal meanings in insurance, and using them loosely will cost marks.

An Insurance Broker Is the Agent of the Insured

An insurance broker acts on behalf of the insured (the client). The broker's primary duty is to the client, not to the insurer. Practical consequences:

• The broker owes the client fiduciary duties, a duty of care, and a duty to follow the client's instructions.
• The broker's knowledge of facts relating to the risk is generally treated as the insured's knowledge, not the insurer's.
• If the broker negligently fails to disclose a material fact to the insurer, the insured (not the insurer) typically bears the consequences — the insured's remedy is to sue the broker for professional negligence.

A Tied Agent or Appointed Representative Is the Agent of the Insurer

A tied agent, an appointed representative, and the insurer's own sales staff act on behalf of the insurer. Practical consequences:

• Their duties are owed to the insurer.
• Their knowledge of facts relating to the risk is generally imputed to the insurer — the insurer is treated as knowing what its agent knows.
• An act within their authority binds the insurer to the insured, even if internal instructions were not followed.

Summary Table

This table is worth memorising. IF1 scenarios frequently ask whether a particular fact (for example, a previous claim, a medical condition, a modification to a vehicle) must be treated as known by the insurer, and the answer turns entirely on whether the person who received the information was the agent of the insurer or of the insured.
