Agency Relationships in Real Estate — Types, Examples, and Exam Tips

What Are Agency Relationships in Real Estate?

An agency relationship in real estate is a fiduciary relationship in which an agent is authorized to act on behalf of a principal — typically a buyer or seller — in property transactions. The real estate license exam tests agency relationships under Contracts & Agency as one of the highest-weighted topics on both the national and state portions.

This article covers the 5 types of agency, how agency relationships are created, what fiduciary duties agents owe, which type is most common, how agency can be terminated, and what exam questions to expect. Five types of agency relationships are tested on the salesperson exam.

What Are the Types of Agency Relationships?

Agency relationships in real estate fall into 5 main categories tested on the licensing exam: buyer’s agent, seller’s agent, dual agent, transaction broker, and designated agent. Each type creates different duties and obligations between the agent and the parties involved.

The type of agency determines who receives loyalty, confidentiality, and advocacy. Misidentifying the agency type on the exam leads to incorrect answers about duties, disclosure, and consent.

What is a buyer’s agent?

A buyer’s agent represents the buyer exclusively in a real estate transaction and owes full fiduciary duties to the buyer. The buyer’s agent helps find properties, negotiate purchase price, and protect the buyer’s financial interests throughout closing.

A buyer agency agreement — a written contract — creates this relationship. The buyer’s agent cannot disclose the buyer’s maximum price or motivation to the seller under any circumstances.

What is a seller’s agent?

A seller’s agent — also called a listing agent — represents the seller and is hired through a listing agreement to market and sell the property. Full fiduciary duties flow to the seller, including confidentiality about the seller’s minimum acceptable price.

Cooperating agents who bring buyers are subagents of the seller unless a separate buyer agency agreement exists. The seller’s agent earns commission only when the property sells under most listing agreement structures.

What is a dual agent?

A dual agency situation arises when one agent represents both the buyer and the seller in the same real estate transaction. This creates inherent conflicts of interest because the agent cannot fully advocate for either party.

Dual agency is illegal or restricted in many states. Where permitted, both parties must give informed written consent. A dual agent cannot disclose either party’s negotiating position to the other.

What is a transaction broker?

A transaction broker facilitates a real estate transaction without representing either party as a fiduciary agent. The transaction broker provides limited services: assisting with paperwork, coordinating communication, and ensuring contractual deadlines are met.

No loyalty or confidentiality duties extend beyond publicly available information. Transaction brokerage is the default relationship in some states, including Colorado, where dual agency is prohibited.

What is a designated agent?

A designated agent is an individual licensee within a brokerage assigned to represent one party exclusively when the brokerage has clients on both sides. This structure solves the dual agency problem by giving each client a dedicated advocate.

Each designated agent owes full fiduciary duties to their assigned client. The supervising broker remains a dual agent while the designated agents represent individual parties within the same firm.

How Are Agency Relationships Created?

Agency relationships in real estate are created through 4 primary methods: express agreement, implied agreement, estoppel, and ratification. Each method carries different legal weight and enforceability.

1. Express agreement — a written contract such as a listing agreement or buyer agency agreement. This is the strongest, most legally defensible method. Example: a seller signs an exclusive right-to-sell listing with a brokerage.

2. Implied agreement — agency created through conduct and actions without a formal written agreement. Example: an agent regularly shows properties and negotiates on a buyer’s behalf without signing a buyer agency form.

3. Agency by estoppel — created when a principal’s actions lead a third party to reasonably believe an agent has authority. Example: a property owner allows someone to negotiate a sale on their behalf without objecting.

4. Ratification — a principal accepts and approves an agent’s unauthorized actions after the fact. Example: an agent submits an offer without authorization, and the principal later agrees to honor it.

Express written agreements are the safest method. Licensing courses and exam questions emphasize written agreements because they prevent disputes over whether agency existed.

What Fiduciary Duties Does an Agent Owe?

An agent in a real estate agency relationship owes 6 fiduciary duties to their principal, remembered by the mnemonic OLDCAR. Each duty is independently testable on the licensing exam.

• Obedience — follow all lawful instructions from the principal
• Loyalty — put the client’s interests above all others, including the agent’s own financial interest
• Disclosure — reveal all material facts that could affect the client’s decisions
• Confidentiality — protect the client’s private information, including financial position and motivation
• Accounting — account for all funds, documents, and property entrusted to the agent
• Reasonable Care — exercise professional competence and diligence in every task

Which duty is most commonly violated? Disclosure — failure to disclose material facts is the leading cause of license discipline across all 50 states. Agents who fail to disclose known property defects, environmental hazards, or conflicts of interest face license suspension, fines, and civil liability.

What Is the Most Common Type of Agency Relationship?

The most common type of agency relationship in real estate is the seller’s agency, established through a listing agreement between the property owner and a licensed broker. Historically, all agents in a transaction were assumed to represent the seller — buyer’s agency did not exist as a separate practice until the 1990s.

Today, buyer agency agreements are increasingly common. Many markets require written buyer representation before an agent can show properties or submit offers. The shift toward mandatory buyer representation has changed how agency disclosure is documented at every stage of the transaction. State licensing laws now require disclosure of agency type at first substantive contact.

Can an Agency Relationship Be Terminated?

Agency relationships in real estate can be terminated through 5 methods recognized by real estate law. Each method carries specific consequences for commission rights and contractual obligations.

1. Mutual agreement — both the principal and agent agree to end the relationship voluntarily.

2. Expiration — the listing agreement or buyer agency agreement reaches its contractual end date.

3. Revocation by principal — the principal cancels the agency, though the agent may be owed damages or commission under the agreement terms.

4. Renunciation by agent — the agent withdraws from the relationship, though doing so may forfeit commission rights.

5. Operation of law — death of either party, legal incapacity, bankruptcy, or destruction of the subject property terminates agency automatically.

Written listing agreements typically include a protection period that survives termination. During this period, the agent earns commission if the property sells to a buyer the agent previously introduced.

What Agency Relationship Questions Appear on the Real Estate Exam?

Agency relationship questions appear on both the national and state portions of the real estate salesperson exam under Contracts & Agency. This topic carries significant weight — expect 8 to 12 questions across both portions combined.

Common exam question patterns include:

• “Which type of agency allows one agent to represent both parties?” — dual agency
• “What duties does an agent owe under OLDCAR?” — obedience, loyalty, disclosure, confidentiality, accounting, reasonable care
• “How is an agency relationship created by conduct without a written agreement?” — implied agency
• “What is the default agency relationship in states that use transaction brokerage?” — transaction broker with no fiduciary duties

On the exam, know the difference between dual agency and designated agency — this is a frequently tested distinction. Dual agency means one agent serves both parties. Designated agency means the brokerage assigns separate agents so each client has an exclusive representative.

How Are Agency Relationships Different from Fiduciary Duties?

Agency relationships define the legal bond between agent and client, while fiduciary duties are the specific obligations that flow from that bond. The agency relationship is the container. Fiduciary duties (OLDCAR) are the contents.

Every agency relationship creates fiduciary duties, but the scope varies by type. Exclusive buyer’s agents and seller’s agents owe all 6 OLDCAR duties. Dual agents have limited duties — loyalty and confidentiality are restricted. Transaction brokers owe no fiduciary duties at all.
