QUICK ANSWER

An agency relationship is one where a principal authorizes an agent to act on their behalf with a third party. Agents are classed by authority: a special agent handles one task (a real estate agent selling a home), a general agent has ongoing authority (a property manager), and a universal agent has unlimited authority (a power of attorney). Agency can be created by express agreement, implied conduct, ratification, or estoppel, and it ends by the acts of the parties or by operation of law. Texas prohibits dual agency and uses the intermediary instead.

Agency is the foundation of the whole Contracts and Agency area, because everything an agent does flows from who they represent. This spoke is part of the Contracts and Agency area. It covers the general agency concepts, while the IABS disclosure and Texas intermediary rules live in their own guides.

The topic breaks into four questions: who are the parties, what type of agent is involved, how was the agency created, and how does it end. Answer those, and the questions fall into place. Let us build it.

What is an agency relationship?

Snippet answer: An agency relationship is a fiduciary relationship in which a principal hires an agent to represent them in dealings with a third party. The principal is the client the agent represents, the agent acts on the principal's behalf, and the third party is the other side, often called the customer. The agent owes the principal fiduciary duties, and owes the customer honesty and fair dealing.

Agency starts with three roles, so learn the vocabulary first. The principal is the person who hires the agent and whose interests the agent serves. The agent is the one authorized to act on the principal's behalf. The third party, often called the customer, is the other side of the transaction.

The relationship is fiduciary, meaning the agent owes the principal a high level of trust and loyalty, covered in the fiduciary duties spoke. The agent still owes the customer honesty and fair treatment, but not the same loyalty. Keep those two duty levels separate, because the exam tests who is owed what.

Types of agents: special, general, universal

Snippet answer: Agents are classified by how much authority they have. A special agent is hired for one specific task, which is what a typical real estate agent is when listing a single home. A general agent has ongoing authority to handle a range of matters, like a property manager running a property. A universal agent has unlimited authority to act for the principal, such as someone holding a full power of attorney.

The scope of authority defines the agent type, and the exam loves to test the examples.

Agent type Authority Real estate example
Special agent One specific task or transaction An agent hired to sell one home
General agent Ongoing authority in a business or area A property manager running a property
Universal agent Unlimited authority to act for the principal A person with full power of attorney

The one to anchor is the special agent, because that is what a real estate sales agent usually is. You are hired for one transaction, and your authority ends when the deal closes or the listing expires. A property manager, by contrast, is a general agent, with authority to lease, collect rent, and manage over time. A universal agent is rare in real estate.

Types of agency: single, sub, and dual

Snippet answer: Agency relationships are also classed by how many parties an agent represents. Single agency means representing only one party, the buyer or the seller, which avoids a conflict of interest. Subagency is when another agent works under the listing broker and represents that same principal. Dual agency means representing both sides at once, and Texas prohibits it, using the intermediary relationship instead.

This is the classification most likely to appear on the Texas exam, because of the Texas twist at the end.

Single agency is the clean case: the agent represents one party, the buyer or the seller, and owes full loyalty to that one principal. Subagency is a traditional arrangement where a cooperating agent works under the listing broker and represents the seller, though it is far less common today with buyer representation.

Dual agency is the trap. It means one agent, or one broker, representing both the buyer and the seller in the same deal. Many states allow it with disclosure and consent, but Texas does not permit dual agency. Instead, a Texas broker who has both parties acts as an intermediary under specific rules, covered in the Texas intermediary practice guide. If a Texas exam answer says an agent may act as a dual agent, be suspicious.

How is an agency relationship created?

Snippet answer: Agency can be created four ways. Express agency comes from a spoken or written agreement, like a listing or buyer-representation agreement. Implied agency arises from the conduct of the parties acting as if a relationship exists. Ratification happens when a principal later approves an act done without prior authority, for that one act. Estoppel prevents a principal from denying an agency they led a third party to believe existed.

Agency does not always require a signed contract, so know all four paths.

Method How it forms
Express A spoken or written agreement between principal and agent
Implied The parties act as though an agency exists, without stating it
Ratification The principal approves an unauthorized act after the fact
Estoppel The principal let a third party reasonably believe an agency existed

Express is the normal case, created by a listing or buyer-representation agreement. Implied agency is the exam trap, because an agent can create it accidentally by acting like someone's representative. Ratification covers only the single act approved, not future acts. Estoppel stops a principal from denying an agency their own conduct created. For safety, agents use written agreements so representation is clear.

Actual versus apparent authority

Snippet answer: An agent's authority comes in two forms. Actual authority is what the principal genuinely gave the agent, whether stated expressly or reasonably implied. Apparent authority, also called ostensible authority, is authority a third party reasonably believes the agent has because of the principal's conduct, even if it was never actually granted. Both can bind the principal, which is why clear agreements matter.

Authority is what lets an agent bind the principal, and it splits two ways. Actual authority is the real thing: what the principal expressly told the agent to do, plus what is reasonably implied to carry that out. If a seller authorizes an agent to market the home, marketing tasks are within actual authority.

Apparent authority is trickier. It exists when the principal's own conduct leads a third party to reasonably believe the agent has authority, even if the principal never granted it. Because apparent authority can still bind the principal, sloppy conduct creates risk. The lesson is that clear, written scope keeps actual and apparent authority aligned.

Agent types and the no-dual-agency rule are prime exam material. Run the free contracts and agency question set to drill them.

How does an agency relationship terminate?

Snippet answer: Agency ends two ways. By the acts of the parties, it ends through completion of the task, expiration of the term, mutual agreement, revocation by the principal, or renunciation by the agent. By operation of law, it ends through death or incapacity of either party, bankruptcy, or destruction of the property. An agency coupled with an interest is the exception: the principal cannot revoke it because the agent holds an interest in the property.

Agency relationships do not last forever, and the exam tests how they end. Group the endings into two buckets.

By acts of the parties By operation of law
Task completed or performed Death or incapacity of either party
Term expired Bankruptcy of the principal
Mutual agreement to end Destruction or condemnation of the property
Revocation by the principal
Renunciation by the agent

There is one important exception. An agency coupled with an interest arises when the agent holds an actual interest in the property that is the subject of the agency. In that case, the principal cannot revoke the agency before the interest ends, and it does not automatically terminate on the principal's death. For the exam, remember that a normal agency can be revoked, but an agency coupled with an interest cannot.

How agency works in Texas

Snippet answer: In Texas, the broker is the agent. A client contracts with a broker, and sponsored sales agents act on behalf of that broker. Texas requires the Information About Brokerage Services (IABS) notice at first substantive communication, prohibits dual agency, and allows a broker with both parties to act as an intermediary under written consent. So agency questions in Texas run through the broker, not the individual sales agent alone.

Texas adds a structural rule that reframes everything above. The broker is the agent of the client, and sales agents act on behalf of their sponsoring broker. So when a client hires representation, the agency relationship is with the broker, and the sales agent carries it out under the broker's license.

Two Texas rules follow. First, the IABS notice must be provided at the first substantive communication about a specific property. Second, because dual agency is prohibited, a broker who ends up with both the buyer and the seller uses the intermediary process instead. Keep the general agency concepts from this spoke, then layer the Texas broker structure on top.

How to study agency relationships for the exam

Snippet answer: Study agency with four questions: who are the parties, what type of agent, how was it created, and how does it end. Anchor the examples, a real estate agent is a special agent and a property manager is a general agent, and the four creation methods of express, implied, ratification, and estoppel. Remember Texas bans dual agency and uses the intermediary, and that an agency coupled with an interest cannot be revoked.

Do not memorize agency as a list of terms. Run the four questions on any fact pattern. Identify the principal, agent, and customer. Classify the agent by authority. Spot how the agency was created, especially accidental implied agency. Then check how it ends.

Keep this spoke tied to its neighbors. The fiduciary duties spoke covers what the agent owes the principal, the duties to clients and minimum services guide covers the Texas statutory duties, and the Contracts and Agency hub ties the area together.

Frequently asked questions

What type of agent is a real estate sales agent? Usually a special agent. A special agent is hired for one specific task, such as listing and selling a single property, and the authority ends when that task is complete. This differs from a general agent, like a property manager, who has ongoing authority to handle many matters over time, and a universal agent, who has unlimited authority through something like a full power of attorney.

Does Texas allow dual agency? No. Texas prohibits dual agency, where one agent or broker represents both the buyer and the seller. Instead, a Texas broker who has obtained both parties can act as an intermediary under specific written-consent rules. If an exam answer describes an agent serving as a dual agent in Texas, it is describing something Texas law does not permit.

What is the difference between actual and apparent authority? Actual authority is what the principal genuinely granted the agent, either expressly or by reasonable implication. Apparent authority is authority a third party reasonably believes the agent has because of the principal's conduct, even if it was never actually granted. Both can bind the principal, which is why agents should keep their authority clearly defined in writing.

What is an agency coupled with an interest? It is an agency in which the agent holds an actual interest in the property that is the subject of the agency. Unlike an ordinary agency, the principal cannot revoke it before the interest ends, and it does not automatically terminate on the principal's death. It is the main exception to the rule that a principal may revoke an agency.

Practice questions

1. An agent is hired to list and sell one specific home. What type of agent is this? A. A general agent B. A universal agent C. A special agent D. A subagent

Answer: C. An agent hired for one specific task, like selling a single home, is a special agent. A general agent has ongoing authority (A), a universal agent has unlimited authority (B), and a subagent works under another agent for the same principal (D).

2. In Texas, a broker has obtained both the buyer and the seller as clients in one transaction. The broker may: A. Act as a dual agent with disclosure B. Act as an intermediary under written consent C. Represent neither party D. Secretly favor the seller

Answer: B. Texas prohibits dual agency, so the broker uses the intermediary process with written consent. Dual agency is not permitted (A), the broker can still facilitate the deal rather than dropping both (C), and favoring one party violates intermediary rules (D).

3. A principal approves an act that an agent already performed without prior authority, adopting it as their own. This creates agency by: A. Estoppel B. Ratification C. Implication D. Express agreement

Answer: B. Ratification is a principal approving an unauthorized act after the fact, creating agency for that act. Estoppel prevents denying an apparent agency (A), implied agency arises from conduct (C), and express agency comes from a stated agreement (D).

4. Which event terminates an agency by operation of law rather than by the acts of the parties? A. The task is completed B. The parties mutually agree to end it C. The principal dies D. The principal revokes the agency

Answer: C. Death or incapacity of a party ends an agency by operation of law. Completion (A), mutual agreement (B), and revocation (D) are terminations by the acts of the parties. Note that an agency coupled with an interest survives the principal's death.
