Arizona Real Estate Exam: Agency Relationships Explained

Last updated: April 2026

Understanding the nuances of agency law is one of the most critical steps in passing your state licensing exam and establishing a successful career as a real estate professional. Governed by the Arizona Department of Real Estate (ADRE) and outlined in Arizona Revised Statutes (A.R.S.) Title 32, agency relationships define the legal responsibilities and ethical boundaries between real estate licensees and the public.

Whether you are representing a first-time homebuyer in Phoenix or listing a commercial property in Tucson, mastering these concepts is non-negotiable. For a comprehensive look at everything you need to know for your upcoming test, be sure to bookmark our Complete Arizona Exam Guide.

What is an Agency Relationship in Arizona?

In real estate, an agency relationship is created when one person (the principal/client) delegates to another (the agent) the right to act on their behalf in business transactions. In Arizona, it is vital to understand a fundamental rule: all agency relationships legally belong to the Designated Broker, not the individual salesperson.

When a seller signs a listing agreement with a real estate agent, the contract is actually between the seller and the agent's employing brokerage. The salesperson acts as a "subagent" to their broker, carrying out the duties on the broker's behalf.

Client vs. Customer

The Arizona real estate exam will frequently test your ability to distinguish between a client and a customer:

Client (Principal): A person who has entered into an express, written agency agreement with a brokerage. The broker and their agents owe this person full fiduciary duties.
Customer: A third party in the transaction who is not represented by your brokerage. While you do not owe them fiduciary duties, Arizona law mandates that you treat all customers with honesty, fairness, and good faith, and disclose any known material facts.

Types of Agency Relationships in Arizona

Arizona recognizes several types of agency relationships. Knowing the distinctions between them is critical for both exam day and real-world practice.

Single Agency

Single agency occurs when a brokerage represents only one party in a transaction—either the buyer or the seller, but never both.

Seller’s Agent: The broker represents the seller. Their primary goal is to secure the highest possible price and best terms for the seller.
Buyer’s Agent: The broker represents the buyer. Their primary goal is to negotiate the lowest possible price and most favorable terms for the buyer.

Dual Agency

Dual agency occurs when the same brokerage represents both the buyer and the seller in the same real estate transaction. Under A.R.S. § 32-2156, dual agency is legal in Arizona only with the prior, express written consent of both parties.

In a dual agency scenario, the broker's fiduciary duties are limited. The agent cannot disclose confidential information, such as the highest price the buyer is willing to pay or the lowest price the seller will accept, without explicit permission. Because of the inherent conflict of interest, dual agency is highly regulated.

Subagency

Though less common in modern Arizona residential real estate due to the rise of buyer broker agreements, subagency occurs when an agent from one brokerage acts on behalf of the listing broker (and therefore the seller) to find a buyer. In this case, the buyer is unrepresented and is treated as a customer.

Fiduciary Duties: The "OLD CAR" Acronym

When an agency relationship is established, the agent owes the principal fiduciary duties. These are the highest standard of care imposed by law. An easy way to remember these for the Arizona exam is the acronym OLD CAR:

Obedience: You must follow all lawful instructions of your client. (If a client asks you to violate the federal Fair Housing Act, you must refuse).
Loyalty: You must put your client’s interests above all others, including your own.
Disclosure: You must disclose all material facts to your client. For a deeper dive into what constitutes proper disclosure and ethical behavior, review our guide on Arizona real estate ethics and standards.
Confidentiality: You must keep your client's personal information (like their motivation for selling or financial status) secret, even after the agency relationship ends.
Accounting: You must account for all funds and documents entrusted to you. In Arizona, brokers must deposit earnest money into a trust account or escrow promptly.
Reasonable Care and Skill: You must use your professional expertise to protect your client. This includes understanding complex regulations, such as ADA compliance in real estate, to properly advise commercial clients.

Creation and Termination of Agency

How Agency is Created

In Arizona, the ADRE strongly prefers that agency relationships be created through an Express Agency agreement. This is a formal, written contract, such as an Exclusive Right to Sell Listing Agreement or a Buyer-Broker Exclusive Employment Agreement.

Beware of Implied Agency, which occurs when an agent's actions lead a consumer to believe they are being represented, even without a written contract. Implied agency can lead to accidental, undisclosed dual agency, which is a violation of Arizona real estate law.

How Agency is Terminated

Agency relationships do not last forever. They can be terminated by:

Performance/Completion: The property closes, and the goal of the agency is met.
Expiration: The term of the listing or buyer agreement runs out.
Mutual Agreement: Both the broker and the client agree to cancel the contract.
Revocation or Renunciation: The client fires the broker, or the broker fires the client (though this may result in a breach of contract claim).
Operation of Law: This includes the death or incapacity of either the principal or the Designated Broker, destruction of the property, or bankruptcy of the principal. Exam Tip: The death of the salesperson does NOT terminate the agency, because the contract is with the broker!

Exam Prep Strategy for Agency Questions

Agency questions make up a significant portion of the Arizona state licensing exam. When reading scenario-based questions, always identify who the principal is, who the agent is (remember, it's the broker), and whether a party is a client or a customer. Applying these rules systematically will help you avoid trick questions. For more tips on tackling scenario-based questions, check out our Arizona practice test strategies.

Frequently Asked Questions (FAQs)

1. Is dual agency legal in Arizona?

Yes, dual agency is legal in Arizona, but it strictly requires the prior, express written consent of both the buyer and the seller. Without written consent, it is an illegal undisclosed dual agency and can result in the loss of your license.

2. What is the difference between a client and a customer under ADRE rules?

A client has signed a written representation agreement with the brokerage and is owed full fiduciary duties (OLD CAR). A customer is an unrepresented third party who is only owed honesty, fairness, and the disclosure of known material facts regarding the property.

3. If a real estate salesperson passes away, what happens to their active listing agreements?

The listing agreements remain valid and active. In Arizona, agency agreements are legally between the client and the Designated Broker, not the individual salesperson. The broker would simply assign a new salesperson to handle the listings.

4. Can an agent disclose that a seller is facing foreclosure to a potential buyer?

No, unless the seller has given the agent explicit written permission to do so. A seller's financial distress is confidential information. Disclosing it without permission violates the fiduciary duty of confidentiality.

5. What is the Real Estate Agency Disclosure and Election (READE) form?

While specific brokerage forms vary, Arizona agents use agency disclosure forms to clearly explain the types of representation available to a consumer before they share any confidential information. This ensures the consumer understands whether the agent is representing them or the other party.
