Chapter Introduction
Few agency questions are more likely to confuse students than the difference between subagency and buyer brokerage. That confusion is understandable because, in both situations, a licensee may be the person speaking with the buyer, showing the property, discussing logistics, and helping move the transaction forward. Yet the law does not define the relationship by physical proximity or conversational contact. It defines the relationship by agency structure.
This is why the chapter matters so much. A buyer may believe a cooperating broker is “my agent” because of the interaction, while in fact the broker may owe fiduciary duties to the seller through subagency. On the other hand, a true buyer’s broker does represent the buyer and may lawfully protect the buyer’s interests within that fiduciary framework. The exam tests this distinction repeatedly because it goes directly to loyalty, confidentiality, disclosure, and advocacy.
Core insight: the person helping the buyer is not necessarily the buyer’s agent. Representation depends on the legal chain of authority, not the appearance of assistance.
1. Who Creates Subagency?
Subagency is not created by the buyer. It is created through the relationship that flows from the original principal and the original agent. In the classic structure, the seller authorizes the listing broker to represent the seller. If another broker enters the transaction under a structure that makes that broker an extension of the listing side, then the cooperating broker may become a subagent of the seller. The subagent therefore owes fiduciary duties to the seller, not to the buyer with whom the subagent may be working directly.
At an elite testing level, students should understand that subagency is about derivative authority. The subagent does not receive authority directly from the buyer. The authority flows down from the original principal through the original agency relationship. That is why the buyer’s belief or comfort level does not itself create buyer representation.
This also explains why the relationship of the principal to the subagent matters so much. The principal may never have met the subagent personally, yet the law still recognizes a fiduciary chain because the subagent is functioning through the original agency structure.
2. The “Blanket Unilateral Offer of Subagency” and Why the Exam Cares About It
Historically, real estate instruction often discussed the “blanket unilateral offer of subagency” as a way to explain how cooperation in a listing environment could create subagency by default. Whether that exact phrase continues to dominate current practice language is less important for exam reasoning than the structural principle behind it: a cooperating broker is not automatically the buyer’s representative simply because the broker finds or assists the buyer.
The real testing point is this: students must recognize that cooperation and compensation do not alone determine representation. A cooperating broker can be compensated and still owe fiduciary duties to the seller through subagency. This is one reason agency disclosure and relationship clarity are so important under New York law.
Exam insight: if the question is asking who is represented, do not answer based on who is being helped. Answer based on how the agency structure was created.
3. Rejecting Subagency and the Rise of Buyer Brokerage
Subagency may be rejected. When it is rejected, the cooperating broker does not step into a fiduciary chain running to the seller through the listing broker. That does not mean brokerage activity must stop. It means the transaction must be structured differently. One important alternative is buyer brokerage, in which the cooperating broker represents the buyer directly rather than serving as a subagent of the seller.
This is a major conceptual shift. Under subagency, the buyer may receive service without fiduciary representation. Under buyer brokerage, the buyer becomes the principal. That changes confidentiality, loyalty, advice, and strategic conduct. The cooperating broker is no longer simply another arm of the listing side. Instead, the broker stands in a direct fiduciary relationship to the buyer.
The exam may therefore ask whether brokerage can be conducted without subagency. The answer is yes. Brokerage can absolutely occur without subagency. But if subagency is rejected, students must be prepared to identify what alternative structure has taken its place.
Textbook Breakdown: Subagent or Buyer’s Broker?
1. The Subagent’s Loyalty Runs to the Seller
+
A subagent owes fiduciary duties to the seller because the subagent derives authority from the listing side of the transaction. This means the subagent must act with loyalty, confidentiality, disclosure, obedience, reasonable care, and accounting in relation to the seller as principal. The fact that the subagent may speak often with the buyer does not alter that fiduciary direction.
This is one of the most important corrections students must make to their intuition. Day-to-day contact does not define the principal. Legal structure does.
2. The Buyer Under Subagency Is Not the Client
+
Under a subagency structure, the buyer may be assisted, informed, and guided through logistics, but the buyer is not the principal receiving fiduciary loyalty from the subagent. The buyer is therefore not entitled to confidential advocacy from that subagent in the way a true client would be. This is a classic exam issue because students often project fiduciary status onto the most visible relationship in the facts.
3. The Buyer’s Broker Represents the Buyer Directly
+
A buyer’s broker stands in a direct agency relationship with the buyer. In this structure, the buyer is the principal, and the broker owes fiduciary duties to the buyer. That means the broker may protect the buyer’s confidential information, help negotiate for the buyer’s best lawful advantage, and provide advice consistent with buyer advocacy.
This is the clearest contrast with subagency. Under subagency, the cooperating broker’s loyalty runs backward to the seller. Under buyer brokerage, loyalty runs directly to the buyer.
4. Brokerage Can Be Conducted Without Subagency
+
Yes, brokerage can be conducted without subagency. This is an important exam answer because some students assume that if the cooperating broker is not a subagent, the broker cannot participate at all. That is incorrect. The broker may instead act as a buyer’s broker, as another form of authorized representative, or within another properly disclosed and lawful structure.
5. The Principal’s Relationship to the Subagent
+
The relationship between the principal and the subagent may feel indirect, but it is still legally meaningful. The seller may not personally appoint the subagent in day-to-day language, yet the subagent’s authority and obligations derive from the seller’s original agency arrangement. Students should therefore recognize that agency can be legally real even when the consumer experience feels mediated through multiple licensees.
4. Obligations of the Subagent to the Seller
The subagent owes the seller the full fiduciary package appropriate to the agency role: loyalty, confidentiality, disclosure of material information, obedience to lawful instructions, reasonable care, and accounting. This means the subagent must protect the seller’s interests even while physically working with a buyer in the transaction.
That is why certain disclosures to the buyer would be improper under subagency. If the buyer tells the subagent something highly favorable to the seller’s negotiating position, the subagent may have obligations that do not align with buyer advocacy. This often surprises students, but it is exactly why agency status must be made clear.
High-level rule: under subagency, the seller is not merely the owner of the property. The seller is the principal to whom fiduciary loyalty runs.
5. Obligations of the Subagent to the Buyer
Even though the subagent does not owe fiduciary duties to the buyer, the subagent is not free to deceive, manipulate, or mislead the buyer. The subagent still owes duties of honesty, fair dealing, and lawful conduct. This is a key exam distinction. The buyer is not abandoned simply because the buyer is not the principal. Rather, the buyer receives a different type of legal protection.
Students should therefore distinguish between fiduciary duty and general obligation of honesty. The subagent may not lie to the buyer. But the subagent also may not provide the buyer with the same confidential, fully aligned advocacy that a true buyer’s broker could provide.
6. How Buyer Brokerage Changes the Entire Analysis
Once the cooperating broker becomes a buyer’s broker, the structure shifts dramatically. The buyer becomes the principal. The broker may now lawfully protect the buyer’s confidences, strategize on the buyer’s behalf, and pursue the buyer’s best lawful interest. This is the relationship most consumers intuitively imagine when they think of “my agent.” But from a legal standpoint, that status must actually exist. It cannot be assumed.
This is why buyer brokerage is so important in New York agency law. It replaces ambiguity with direct representation. It gives the buyer a clearly identifiable fiduciary advocate. The exam often tests this by comparing two otherwise similar scenarios in which one cooperating broker is a subagent and the other is a buyer’s broker. The visible conduct may look the same, but the legal meaning is completely different.
Examples That Reflect New York Testing Logic
Example 1: Cooperating Broker as Subagent
A broker from another office shows a listed property to a buyer and helps prepare the offer. The buyer assumes this broker is “my agent.” But if the broker entered the transaction through the listing side in a subagency structure, fiduciary duties still run to the seller.
Example 2: Buyer Brokerage Instead of Subagency
A buyer signs a buyer representation agreement with a broker before viewing homes. Now, when that broker shows the buyer listed properties, the broker is acting as the buyer’s broker, not as a subagent of the seller.
Example 3: Brokerage Without Subagency
A cooperating broker rejects subagency and does not represent the seller through the listing broker. The broker still participates in the transaction, but does so under a different relationship structure, such as buyer brokerage.
Study takeaway: the question is never just “Who is helping the buyer?” The real question is “To whom does this licensee owe fiduciary loyalty?”
What New York Wants You to Know for the State Exam
- Subagency is created through the original agency chain, not by the buyer.
- A subagent may work with a buyer while owing fiduciary duties to the seller.
- The buyer under subagency is not the client of the subagent.
- A buyer’s broker represents the buyer directly and owes fiduciary duties to the buyer.
- Brokerage can be conducted without subagency.
- Rejecting subagency does not end brokerage activity; it changes the representation structure.
- Under subagency, the buyer is still owed honesty and fair dealing, even though fiduciary loyalty runs to the seller.
High-yield memory phrase: subagency follows the seller; buyer brokerage follows the buyer.

Chapter Conclusion
Subagency and buyer brokerage are often confused because the visible conduct in the transaction can look nearly identical. In both structures, the buyer may speak to the same broker, tour the same property, and submit the same offer through the same channel. But the law is not measuring surface similarity. It is measuring representation.
Students who want strong exam performance should therefore build a disciplined habit: when a cooperating broker appears, immediately ask whether the broker’s loyalty runs back to the seller through subagency or directly to the buyer through buyer brokerage. Once that question is answered, the rest of the legal analysis becomes far clearer. That is the essential skill this chapter is designed to produce.
