Real Estate License Types of Agency: Buyer, Seller, Dual, Designated

Last updated: May 2, 2026

Types of Agency: Buyer, Seller, Dual, Designated questions are one of the highest-leverage areas to study for the Real Estate License. This guide breaks down the rule, the elements you need to recognize, the named traps that catch most students, and a memory aid that scales to test day. Read it once, then practice the same sub-topic adaptively in the app.

The rule

Agency in real estate is the legal relationship in which a licensee (the agent) owes fiduciary duties to a principal (the client). The four core forms tested are seller agency, buyer agency, dual agency, and designated agency. Single agency (representing only one side) carries the full bundle of fiduciary duties — commonly remembered as OLD CAR (Obedience, Loyalty, Disclosure, Confidentiality, Accounting, Reasonable care). Dual agency requires informed written consent from both parties and reduces the agent to limited or 'facilitator' duties; designated agency lets one brokerage assign different in-house licensees to each side, preserving full fiduciary duties to each client at the agent level while the broker remains a dual agent.

Elements breakdown

Seller Agency (Listing Agency)

The licensee represents the seller as client; the buyer is a customer entitled to honesty and material defect disclosure but not fiduciary duties.

  • Created by written listing agreement
  • Full OLD CAR duties to seller
  • Buyer treated as customer, not client
  • Cooperating subagency now disfavored in most states

Buyer Agency

The licensee represents the buyer as client, typically under a written buyer-representation agreement; the seller is the customer.

  • Written buyer agreement increasingly required
  • Full OLD CAR duties to buyer
  • Compensation may come from seller, buyer, or split
  • Must disclose buyer-agency status to listing side

Dual Agency

One licensee (or one brokerage with no designation) represents both buyer and seller in the same transaction.

  • Requires informed written consent from both
  • Illegal in some states (e.g., several have banned it)
  • Agent becomes neutral; cannot advocate price or terms
  • Confidential information of either side must not be shared
  • Cannot disclose seller's lowest price or buyer's highest offer

Designated Agency

Within a single brokerage, the broker designates one licensee to represent the seller and a different licensee to represent the buyer; each designated agent owes full fiduciary duties to their assigned client.

  • Permitted only where state statute authorizes it
  • Broker remains a dual agent at firm level
  • Designated agents owe full single-agency duties
  • Firewall must protect confidential information
  • Written disclosure and consent typically required

Subagency

A cooperating broker from another firm represents the seller through the listing broker rather than the buyer; largely abandoned today but still tested.

  • Created via MLS offer of subagency
  • Cooperating agent owes duties to seller, not buyer
  • Buyer is a customer in this arrangement
  • Must be disclosed to the buyer up front

Transactional / Non-Agency Brokerage

A 'facilitator' or 'transaction broker' assists both parties to close the deal without representing either as a client; recognized in some states only.

  • No fiduciary duties owed
  • Owes honesty, accounting, statutory disclosures
  • Often used as alternative to dual agency
  • Status must be disclosed in writing

Common patterns and traps

Customer-Mistaken-For-Client Trap

The fact pattern shows a buyer working casually with a listing agent, asking advice, even sharing motivation and budget. The candidate is tempted to treat the buyer as a client and demand full fiduciary duties. Without a written buyer-representation agreement (or in subagency states, without a buyer-agency disclosure), the buyer is a customer of the listing firm and the agent's loyalty remains with the seller.

A choice that says the agent must keep the buyer's maximum price confidential from the seller, when no buyer-agency relationship has been formed.

Silent Dual Agency Trap

One licensee ends up working with both sides — often because their own buyer wants to see their own listing — but no written consent is obtained. Undisclosed dual agency is a per se violation of license law in virtually every state and is grounds for discipline, commission forfeiture, and rescission. Exam writers love to hide this in a friendly-sounding fact pattern.

A choice that says the arrangement is fine because the agent 'treated both parties fairly' or 'didn't share confidential information.'

Designated-Equals-Dual Confusion

Candidates assume that because the brokerage is dual at the firm level, the individual designated agents owe only limited duties. In a properly executed designated agency, each assigned agent owes full single-agency fiduciary duties to their client, including loyalty and full disclosure of material facts the agent personally knows.

A choice that says a designated buyer's agent cannot advise the buyer on what price to offer.

Disclosure-Timing Trap

Agency disclosure has a state-mandated trigger — usually 'first substantive contact' or before any confidential information is exchanged, and always before any offer is signed. Wrong choices push the timing to closing, to the listing presentation only, or treat verbal disclosure as sufficient when the state requires writing.

A choice that says agency disclosure can be made at the closing table or only when an offer is presented.

Confidentiality-Survives-Closing Trap

The duty of confidentiality outlasts the agency relationship. Even after closing or termination of the listing, the agent cannot reveal the former client's motivation, financial position, or willingness to accept different terms. Wrong answers suggest the duty ends when the deal closes.

A choice that says once the transaction closes, the former agent may freely tell a new buyer how low the prior seller was willing to go.

How it works

Picture a brokerage, Reyes Realty Group, where licensee Mara has the listing on a $410,000 ranch home and licensee Devon is working with a buyer interested in that exact property. If Mara alone tries to represent both sides, she becomes a dual agent and must obtain written consent from both parties; she can no longer advise either on price strategy. If the broker-in-charge instead designates Mara to the seller and Devon to the buyer, the firm is in designated agency: Mara still owes full loyalty and confidentiality to the seller, Devon owes the same to the buyer, and the broker manages the conflict at the top. The buyer-as-customer trap appears when Devon is actually the listing agent and a walk-in buyer assumes Devon is 'their' agent — without a written buyer agreement, that buyer is just a customer and Devon's loyalty stays with the seller. Exam questions almost always hinge on (1) who the client is, (2) whether consent is in writing, and (3) what the agent may or may not disclose.

Worked examples

Worked Example 1

Under standard agency principles, what is Priya's correct course of action?

  • A Treat Marcus as her client because he disclosed his maximum price, and keep that figure confidential from her seller.
  • B Provide written agency disclosure identifying her as the seller's agent, treat Marcus as a customer, and inform her seller that Marcus is willing to pay up to $400,000. ✓ Correct
  • C Become a dual agent automatically since she is now working with both sides, and proceed to write the offer.
  • D Refuse to discuss the property further with Marcus until he hires his own buyer's agent.
  • E placeholder

Why B is correct: Without a written buyer-agency agreement, Marcus is a customer of the listing firm, and Priya's fiduciary duties — including loyalty and disclosure of material facts — run to her seller-client. Priya is required to deliver the written agency disclosure and must pass along the buyer's stated willingness to pay more, because that information is material to the seller's decision. Dual agency does not arise without informed written consent from both parties.

Why each wrong choice fails:

  • A: Marcus never became Priya's client — there is no written buyer-agency agreement — so Priya owes him no duty of confidentiality. Withholding the higher price from her actual client (the seller) would breach loyalty and disclosure. (Customer-Mistaken-For-Client Trap)
  • C: Dual agency is never automatic. It requires informed, written consent from both buyer and seller; simply working with both sides without that consent is undisclosed dual agency and a license-law violation. (Silent Dual Agency Trap)
  • D: Priya is allowed — and indeed obligated — to continue marketing her seller's property to interested customers. Refusing to engage with an unrepresented buyer would breach her duty of obedience and reasonable care to the seller.
Worked Example 2

Which statement most accurately describes the agents' duties under this designated agency arrangement?

  • A Elena and Brent each owe only the limited duties of a dual agent and may not advise their clients on price.
  • B Elena owes full fiduciary duties to the Patels and Brent owes full fiduciary duties to the Nguyens; Harrison is a dual agent at the firm level and must maintain a confidentiality firewall. ✓ Correct
  • C Because the brokerage represents both sides, Elena and Brent must share all confidential information they receive with each other to ensure transparency.
  • D Designated agency is invalid in any transaction where the buyer and seller are represented by salespersons of the same broker.
  • E placeholder

Why B is correct: Properly executed designated agency lets each assigned licensee continue to owe full single-agency fiduciary duties — loyalty, obedience, disclosure, confidentiality, accounting, and reasonable care — to their respective client. The broker-in-charge sits at the firm level as a dual agent and must keep the two sides' confidential information separated. This is the entire purpose of designated agency: preserving advocacy at the salesperson level.

Why each wrong choice fails:

  • A: This is the classic designated-equals-dual confusion. In designated agency the salesperson is NOT a dual agent; they retain full fiduciary duties and may absolutely advise their client on price strategy. (Designated-Equals-Dual Confusion)
  • C: Sharing confidential information between the two designated agents would defeat the entire mechanism. Each agent's confidentiality duty to their own client requires a firewall, not transparency between the agents.
  • D: Designated agency is specifically the statutory tool many states created to handle in-house transactions. Where authorized, it is valid precisely because the broker designates separate licensees to each side.
Worked Example 3

What is Tomasz permitted to say?

  • A He may share that the Hendersons paid full asking price quickly because of personal pressure, since the transaction is closed.
  • B He may reveal the Hendersons' divorce because public records would show it anyway.
  • C He must not disclose the Hendersons' motivation, financial position, or willingness to pay full price; the duty of confidentiality survives the termination of the agency relationship. ✓ Correct
  • D He may share the information only if his current buyer signs a confidentiality agreement.
  • E placeholder

Why C is correct: The fiduciary duty of confidentiality outlives the agency relationship indefinitely. Information learned in confidence — motivation, financial pressure, willingness to pay above market — cannot be disclosed to a future client, even after the original transaction has closed. This is one of the most heavily tested points on agency duties.

Why each wrong choice fails:

  • A: Closing does not terminate the duty of confidentiality. Disclosing a former client's pricing strategy or motivation is a breach regardless of how much time has passed. (Confidentiality-Survives-Closing Trap)
  • B: Whether information is independently available in public records does not authorize the agent to share it. The duty arises from the confidential relationship, not the secrecy of the underlying fact. (Confidentiality-Survives-Closing Trap)
  • D: A confidentiality agreement with the new buyer cannot waive the former client's right to confidentiality. Only the former client can release the agent from the duty, and even then only as to information they own.

Memory aid

OLD CAR for fiduciary duties (Obedience, Loyalty, Disclosure, Confidentiality, Accounting, Reasonable care). For agency type, ask: Who signed what? No written agreement = customer, not client.

Key distinction

In dual agency, the SAME licensee represents both sides and duties are reduced to neutrality. In designated agency, DIFFERENT licensees in the same firm represent each side and full fiduciary duties survive at the agent level.

Summary

Identify the client by the written agreement, then match the agency type to what the agent is allowed to say, do, and disclose.
