Authority of an Agent: Actual and Apparent Authority

Updated 11 October 2026 · Fact-checked

Authority is the power of an agent to bind the principal in contracts with third parties. Actual authority comes from what the principal agreed with the agent, either express or implied. Apparent authority arises from the principal's representation to the third party. If any type exists, the principal is bound.

Understand Authority of an Agent

An agent is a person who has power to change the legal position of another person, the principal, with third parties. The key question in most exam scenarios is: did the agent have authority when the contract was made? If yes, the principal is bound and the agent normally drops out.

Actual authority is the authority the principal really gave the agent. It comes in two forms. Express actual authority is stated in words, spoken or written. For example, "you may buy up to 100 units of stock for me". Implied actual authority is not stated but is inferred. It covers what is necessary or usual to do the job, from the agent's position or role, the nature of the business, or a course of dealing between the parties.

Apparent (ostensible) authority is different. It is not about what the principal told the agent. It is about what the principal led the third party to believe. It arises where the principal makes a representation, by words or conduct (including placing the agent in a position that normally carries that authority), that the agent has authority. The third party relies on it. The principal is then estopped (prevented) from denying the agent's authority, even if the agent was told not to act.

The case usually cited for apparent authority is Freeman and Lockyer v Buckhurst Park Properties (Mangal) Ltd. A director acted as managing director with the board's knowledge, though he was never appointed. The company had allowed him to act that way, so it was bound. The case sets out the conditions: a representation that the agent has authority, made by someone with actual authority to manage the business, reliance by the third party, and the company being able to give that authority under its constitution.

So the quick contrast is this. Actual authority is the relationship between principal and agent. Apparent authority is the relationship between principal and third party. A principal can be bound under apparent authority and then claim against the agent for acting beyond instructions.

Key formulas to remember

Principal bound: Actual authority (express or implied) OR apparent authority → principal bound to third party; Only one type is needed. Check actual first, then apparent.
Express actual authority: Principal's words or writing to the agent → authority; Limited to what the instruction covers, read in a sensible way.
Implied actual authority: Necessary for the task / usual for the role / course of dealing → authority; Cannot override an express limit the principal gave the agent.
Apparent authority conditions: Representation by principal + reliance by third party + principal able to give that authority; The representation must come from the principal, not from the agent alone. The third party must not know the agent lacks authority.
Agent acting outside authority: No actual or apparent authority → principal not bound unless ratifies; agent may be liable for breach of warranty of authority; Ratification must be by a principal who existed and had capacity when the act was done, and must cover the whole act.

How to solve Authority of an Agent questions

Use the same order for every authority scenario. It keeps you from missing a type of authority and gives a clear written answer.

1Identify the principal, the agent and the third party, and the contract made.
2Ask what the principal actually told the agent. If the act was within the instructions, there is express actual authority.
3If not, ask whether the act was necessary or usual for the agent's role or business, or fits past dealings. If so, there is implied actual authority. Check that no express limit blocks it.
4If actual authority fails, look at what the principal said or did towards the third party. Was there a representation that the agent could act? Did the third party rely on it, in good faith, without knowing of the limit?
5State the conclusion: is the principal bound? Name the type of authority that applies.
6If no authority exists, consider ratification by the principal and the agent's personal liability for breach of warranty of authority.
7Add the effect: the principal is liable on the contract, and the agent can be liable to the principal for exceeding instructions.

Quickest way: Three-question authority check

When to use it: For Section A and Section B objective questions where you have about a minute per question.

Q1: Did the principal tell the agent to do this? Yes → express actual authority → principal bound.
Q2: Is it a normal part of this agent's role? Yes, and no ban given → implied actual authority → principal bound.
Q3: Did the principal make the third party think the agent could do it, and does the third party have no knowledge of the limit? Yes → apparent authority → principal bound.
If all three are no, the principal is not bound unless they ratify. The agent may be liable to the third party.

Common mistakes in Authority of an Agent

Saying the principal is not bound because the agent ignored instructions.
Students look only at the principal-agent relationship and forget the third party.
Fix: Always test apparent authority next. A secret limit does not bind a third party who relied on a representation.
Treating apparent authority as created by the agent's own claim.
Students think any statement 'I am authorised' is enough.
Fix: The representation must come from the principal, or someone the principal allows to speak for them. An agent cannot create their own apparent authority.
Confusing implied actual authority with apparent authority.
Both are not written down, so they look alike.
Fix: Implied authority is real authority between principal and agent. Apparent authority is a representation to the third party. Ask who is relying on what.
Allowing apparent authority when the third party knew of the limit.
Students focus on the principal's conduct and ignore the third party's knowledge.
Fix: Reliance needs good faith. If the third party knew, or was clearly put on inquiry, there is no apparent authority.
Forgetting the agent's own liability.
Students stop once they decide whether the principal is bound.
Fix: If no authority and no ratification, say the agent may be liable for breach of warranty of authority. If the principal is bound under apparent authority, the agent may owe the principal damages.
Overstating Freeman and Lockyer as covering any employee.
Students remember the result and not the conditions.
Fix: Quote the conditions. The principal's representation, reliance, and the principal's capacity to give that authority must all be there.

Worked examples

Example 1

Anil is a purchasing manager at Rao Ltd. The board told him to buy raw materials of up to $50,000 per order. He orders materials of $30,000 from Seller Co. Seller Co later asks if Rao Ltd is bound. Advise.

Show the solution

Principal: Rao Ltd. Agent: Anil. Third party: Seller Co.
The board expressly allowed orders up to $50,000.
The $30,000 order is within that limit, so Anil had express actual authority.
No need to rely on apparent authority, because actual authority is enough.

Answer: Rao Ltd is bound by the contract with Seller Co, because Anil acted within his express actual authority.

Example 2

Meera runs a shop and tells her assistant Dev never to buy stock above $2,000 without her approval. Dev has been buying stock for her for years. She has let Dev deal with Supplier Ltd on his own, and Supplier Ltd does not know about the limit. Dev orders $5,000 of stock from Supplier Ltd. Is Meera bound?

Show the solution

Principal: Meera. Agent: Dev. Third party: Supplier Ltd.
Express actual authority: Meera set a limit of $2,000, so the $5,000 order is outside it.
Implied actual authority: buying stock is usual for Dev's role, but the express limit overrides it, so it does not cover this order.
Apparent authority: Meera allowed Dev to deal with Supplier Ltd on his own over time, which is a representation by conduct that he could buy stock.
Supplier Ltd relied on this and did not know of the limit, so reliance in good faith is met. Meera could give this authority herself.
So Meera is estopped from denying Dev's authority.

Answer: Meera is bound to Supplier Ltd under apparent authority. She may be able to claim against Dev for exceeding her instructions.

Exam tips

In Section B scenarios, underline who made a statement to the third party. That is your evidence for apparent authority.
Always give the type of authority by name. A bare 'bound' or 'not bound' answer can lose the mark in an all-or-nothing question.
Watch for words such as 'unknown to the third party' or 'the third party knew'. They usually decide the answer.
In Section A, if an option says apparent authority is created by the agent's own statement, treat it as wrong.
Link authority with the next steps: ratification, liability of the agent, and termination. Scenarios often combine them.

Authority of an Agent: frequently asked questions

What is the difference between actual and apparent authority?

Actual authority is what the principal gave the agent, in words (express) or by inference from the role or dealings (implied). Apparent authority is created by the principal's representation to the third party. Actual is between principal and agent. Apparent is between principal and third party.

What did Freeman and Lockyer v Buckhurst Park decide?

A company was held bound by contracts made by a director who acted as managing director, as the board knew and allowed it. The case gives the conditions for apparent authority: a representation, reliance, and the company's ability to give that authority. It is the case most often cited on this point.

How does apparent authority bind the principal?

The principal made the third party believe the agent had authority, and the third party relied on that. The principal is then estopped from denying it. The contract binds the principal even if the agent had no actual authority.

Can an agent be liable if there is no authority?

Yes. If there is no actual or apparent authority and the principal does not ratify, the agent may be liable to the third party for breach of warranty of authority. The principal is not bound.
