Playbook 1: The Agency Relationship Playbook

Formation, Duties & Termination

Last Verified: 2026-09-06 | Author: Kateule Sydney | Published by E-cyclopedia Resources
Agency law governs the fiduciary relationship between principal and agent — a cornerstone of commercial and tort liability.

Summary: This playbook dissects the agency relationship from formation to termination, covering consent, control, fiduciary duties, and key case law drawn from Bowstead & Reynolds and Oxford Law Pro authorities.

Chapter 1 — Defining the Agency Relationship

1.1 Key Elements: Consent, Control & Fiduciary Nature

Agency is a consensual fiduciary relationship in which one person (the agent) acts on behalf of another (the principal) and is subject to the principal's control. The relationship arises when the principal manifests assent to the agent that the agent shall act on the principal's behalf and subject to the principal's control, and the agent consents so to act.

Three pillars define the relationship:

  • Consent: Both parties voluntarily enter the relationship — no agency without mutual assent.
  • Control: The principal has the right to direct the agent's conduct in matters entrusted to the agent.
  • Fiduciary nature: The agent owes duties of loyalty, care, and good faith — the highest standard known to law.
1.2 Distinguishing Agency from Other Relationships

Agency is narrower than "employment" or "service" — it specifically involves the power to bind the principal legally. A servant or employee may or may not be an agent depending on whether they have authority to enter into contracts on the principal's behalf.

  • Independent contractor: Generally not an agent because the principal lacks control over the manner of work.
  • Bailee: Holds goods but does not represent the bailor in transactions.
  • Trustee: Holds legal title for beneficiary — fiduciary but not necessarily an agent.

Chapter 2 — How Agency Is Created

2.1 Express, Implied, and Apparent Authority

Authority is the agent's power to affect the principal's legal relations. It arises in three primary forms:

  • Express authority: Granted by written or oral words — e.g., a power of attorney or board resolution.
  • Implied authority: Incidental to express authority — includes acts reasonably necessary to carry out the express mandate.
  • Apparent authority: Arises from the principal's manifestations to third parties — even if no actual authority exists, the principal may be bound if they "cloaked" the agent with indicia of authority.

Key case: In Law Debenture Trust Corp Plc v Ukraine [2023] UKSC 11, the Supreme Court examined the boundaries of actual and apparent authority in sovereign debt transactions, clarifying when a state is bound by its agent's representations.

2.2 Agency by Estoppel and Ratification

Agency by estoppel (or apparent authority) binds the principal where the principal's conduct leads a third party to reasonably believe the agent has authority, and the third party relies on that belief to their detriment.

Ratification occurs when a principal later affirms an agent's unauthorized act, retroactively creating agency authority. Ratification requires the principal to have full knowledge of all material facts and to accept the transaction with the intention of being bound.

Chapter 3 — Fiduciary Duties of the Agent

3.1 Duty of Loyalty — Conflicts, Secret Profits, Competition

The duty of loyalty is the "hard core" of fiduciary obligation. An agent must act solely in the principal's interest and avoid any conflict of interest. This includes:

  • No secret profits: Any profit obtained by the agent in connection with the agency belongs to the principal.
  • No undisclosed conflicts: The agent must disclose any personal interest in a transaction.
  • No competition: During the agency, the agent may not compete with the principal's business unless fully disclosed and consented to.

Key case: In Wood v Commercial First Business Ltd [2021] EWCA Civ 471, the Court of Appeal addressed bribes and secret commissions, affirming that an agent who receives a secret commission must account for it and may forfeit their remuneration.

3.2 Duty of Care, Skill, and Diligence

An agent must perform their duties with the care and skill reasonably expected given their profession or representation. A gratuitous agent is held to a lower standard than a paid agent, but all agents must exercise at least reasonable care.

  • Professional agents (solicitors, brokers) are held to the standard of their profession.
  • Special skill — if the agent professes special expertise, they are liable for failing to exercise it.
3.3 Duty to Account and Disclose Information

The agent must maintain accurate accounts of all transactions undertaken on the principal's behalf and disclose all material information that might affect the principal's decisions. This duty persists even after the agency terminates.

Chapter 4 — Principal's Corresponding Obligations

4.1 Indemnification, Compensation, and Cooperation

The principal owes reciprocal obligations to the agent:

  • Indemnification: The principal must reimburse the agent for all expenses and losses incurred in the proper execution of the agency.
  • Compensation: Unless the agency is gratuitous, the principal must pay the agreed remuneration (or reasonable quantum meruit if no amount is fixed).
  • Duty to cooperate: The principal may not prevent the agent from performing their duties and must provide necessary information and facilities.

Key case: In Barton v Morris [2023] UKSC 3, the Supreme Court considered the scope of quantum meruit for services rendered by an agent, clarifying when an agent can claim restitutionary remuneration in the absence of a contract.

Chapter 5 — Termination of Agency

5.1 Mutual Agreement, Lapse of Time, or Accomplishment

Agency terminates by:

  • Mutual agreement: The parties may terminate by express or implied consent.
  • Lapse of time: If the agency is for a fixed period, it ends on expiry.
  • Accomplishment of purpose: Once the specific task is completed, the agency ends.
5.2 Operation of Law — Death, Incapacity, Bankruptcy

Termination occurs automatically by operation of law:

  • Death of either the principal or the agent terminates the agency immediately — unless the agency is coupled with an interest.
  • Incapacity — mental incapacity or loss of legal capacity ends the agency.
  • Bankruptcy — if the principal becomes bankrupt, the agent's authority generally terminates, subject to exceptions under insolvency law.

Note: The principal's death does not automatically terminate apparent authority in relation to third parties who have no notice of the death.

5.3 Irrevocable Agencies — Agency Coupled with an Interest

An agency is "coupled with an interest" when the agent holds a proprietary interest in the subject matter of the agency. Such agencies are irrevocable — the principal cannot terminate them unilaterally, and they survive the principal's death.

  • Example: A mortgagee who is appointed to sell mortgaged property has an agency coupled with an interest.
  • Key distinction: The interest must be in the subject matter itself, not merely a right to commission.

Chapter 6 — Key Case Clips: Formation, Duties & Termination Disputes

⚖️ Law Debenture Trust Corp Plc v Ukraine [2023] UKSC 11 — Authority
The Supreme Court clarified the limits of actual and apparent authority in the context of sovereign debt, holding that a state is not bound by an agent's representations unless the agent had actual authority or the state cloaked the agent with apparent authority.

⚖️ Wood v Commercial First Business Ltd [2021] EWCA Civ 471 — Duty of Loyalty (Secret Profits)
The Court of Appeal reaffirmed that an agent who receives a secret commission or bribe must account for the profit to the principal and may forfeit all remuneration, even if the principal suffered no loss.

⚖️ Barton v Morris [2023] UKSC 3 — Remuneration / Quantum Meruit
The Supreme Court ruled that an agent who performs services without a fixed remuneration agreement may claim quantum meruit only where the circumstances justify restitution, rejecting an automatic entitlement.

⚖️ Philipp v Barclays Bank UK Plc [2023] UKSC 25 — Actual and Apparent Authority
The Supreme Court examined the scope of actual and apparent authority in banking transactions, reinforcing that banks are not automatically liable for their agents' misrepresentations absent clear authority.

⚖️ Barclay-Watt v Alpha Panareti Public Ltd [2022] EWCA Civ 1169 — Agent's Liability for Misrepresentation
The Court of Appeal considered joint tortfeasance and an agent's personal liability for misrepresentations made in the course of the agency, confirming that an agent can be personally liable even when acting for a disclosed principal.

FAQ

What is the difference between actual and apparent authority?

Actual authority is created by the principal's direct manifestation to the agent (express or implied). Apparent authority arises from the principal's manifestation to a third party — even if the agent has no actual authority, the principal may be bound if they "held out" the agent as having authority and the third party reasonably relied on that.

Can an agent bind a principal after the agency has terminated?

Generally, no — termination ends the agent's authority. However, the principal may remain bound to third parties who had no notice of termination if the agent had apparent authority. Good practice requires the principal to give clear notice of termination to all known third parties.

What happens if an agent acts without authority?

If an agent acts without authority, the principal is generally not bound. However, the principal may ratify the act (retroactively conferring authority), or third parties may hold the agent personally liable for breach of warranty of authority. Estoppel may also bind the principal if they contributed to the appearance of authority.
