Dual Agency
Dual agency is when one agent represents both the buyer and the seller (or both landlord and tenant) in the same transaction. Because the agent can no longer give either side undivided loyalty or full disclosure, both parties must give written, informed consent before it can happen, and the agent must stay strictly neutral on price and negotiating strategy for the rest of the deal.
Agency is one of the most heavily tested sections on the national exam, and dual agency is its trickiest scenario. Expect questions asking what an agent can and can't disclose once dual agency is in place, and questions that test whether you can tell dual agency apart from subagency and designated agency.
One agent, two clients, one problem
Dual agency happens when a single agent ends up representing both the buyer and the seller in the same transaction, most commonly when a buyer becomes interested in a home listed by their own agent's brokerage, or when the same agent works with both sides directly. The problem is structural: full fiduciary duty requires undivided loyalty and full disclosure to one client, and an agent can't give either of those things fully to two people negotiating against each other.
Because of that conflict, dual agency is only allowed with informed, written consent from both parties. The disclosure has to happen before the agent proceeds in the dual role, and it has to explain exactly what the client is giving up: full advocacy and confidential handling of their negotiating position.
What the agent can still do, and what they can't
A dual agent doesn't lose every duty. They still owe both parties honesty, fair dealing, accounting for funds and documents, and reasonable care and skill. What they lose is undivided loyalty (they can't push for the best possible price for one side at the other's expense) and full disclosure (they can't share confidential facts like a seller's rock-bottom price or a buyer's maximum budget with the other party). The agent essentially becomes a neutral facilitator rather than an advocate, which is why some states restrict or ban the practice outright in favor of alternatives.
The alternative: designated agency
Many brokerages avoid the conflict with designated agency: the brokerage represents both the buyer and seller, but two different agents within the firm are each designated to represent only one side. Each designated agent keeps full fiduciary duties, including undivided loyalty and confidentiality, toward their own client, and doesn't share that client's confidential information with the other designated agent. This preserves full representation for both sides in a way a single dual agent structurally cannot.
How it appears on the exam
Expect scenario questions where an agent already in a dual agency role is asked, or tempted, to share one client's private information with the other, and you have to identify that doing so breaches the agent's remaining duties. Expect definitional questions distinguishing dual agency (one agent, both parties) from subagency (an agent representing only the seller through the listing broker) and designated agency (two different agents at one brokerage, each representing one side). The fastest way through all three: count how many agents are involved and ask whose interests each one is actually allowed to advocate for.
Memory trick
COIN
What changes once dual agency begins: remember C-O-I-N.
- C
Consent required: both parties must agree to the dual agency in writing before it starts, with full knowledge of what it means
- O
Others' confidences stay sealed: the agent can't reveal one side's motivation, urgency, or price flexibility to the other
- I
Impartial only: the agent can't advocate, negotiate, or give strategic advice that favors either party
- N
No full loyalty or disclosure: two of the six fiduciary duties are necessarily limited; the agent still owes honesty, accounting, and reasonable care to both

How the exam tricks you on this
The most common trap is an agent who leaks one side's motivation to the other under the guise of helping the deal along. If a dual agent tells the buyer "the seller really needs to sell fast" or tells the seller "the buyer will probably go higher," that's a breach, even if it's true and even if it speeds up the sale. Once dual agency is in place, the agent's job is to stay neutral, not to broker information between two clients who each expect confidentiality.
Two more patterns to watch for:
- Dual agency vs. subagency. Subagency is a different structure entirely: a cooperating broker (and their agents) work on behalf of the listing broker, and therefore represent only the seller, never the buyer. If a question describes an agent representing just one side through another broker's listing, that's subagency, not dual agency.
- Dual agency vs. designated agency. Some states allow designated agency, where two different agents at the same brokerage each represent one side of the deal exclusively, one for the buyer, one for the seller. Each designated agent owes full, undivided loyalty to their own client. That's not dual agency; dual agency exists only when a single agent represents both parties personally.

Escrow is a neutral third-party arrangement that holds money and documents on behalf of a buyer and seller until every condition of the sale contract has been met. The escrow agent has no stake in the transaction: they simply follow the escrow instructions both parties signed, releasing funds and title only when every condition clears.
