Yes. In most of the United States, a real estate agent can represent both the buyer and the seller in the same transaction, an arrangement called dual agency. Eight states ban it outright, and every state that allows it requires written consent from both parties. The catch is what you give up by agreeing: the agent stops being your advocate and becomes a neutral middleman who cannot advise you on price, negotiation, or strategy.
What Dual Agency Actually Is
In a normal sale, you hire an agent who owes you fiduciary duties: loyalty, confidentiality, and a legal obligation to put your interests ahead of the other side’s. The agent across the table owes the same duties to their client. Two advocates pulling in opposite directions is what produces a fair price.
Dual agency collapses that structure. One agent, or two agents working under the same brokerage, handles both sides. The moment that happens, the adversarial dynamic disappears. The same person cannot fight to drive the price down for you and drive it up for the seller. Those goals are directly opposed, and professionalism does not resolve the conflict; it only manages it.
States That Ban Dual Agency
Eight states prohibit dual agency entirely: Alaska, Colorado, Florida, Kansas, Maryland, Texas, Vermont, and Wyoming. In those states, one agent cannot represent both sides of the same deal under any circumstances. The remaining states and the District of Columbia allow it, subject to disclosure and consent rules.
Some of the states that ban traditional dual agency still allow transaction brokerage, a related but narrower arrangement covered further down.
What the Agent Can and Cannot Do
Once dual agency kicks in, the agent switches from advocate to referee. The practical limits are significant:
- No negotiation advice. The agent cannot tell the buyer what to offer or tell the seller what to accept.
- No sharing of confidential information. The agent cannot tell the buyer that the seller would take less, or tell the seller that the buyer could pay more.
- No strategic recommendations. The agent cannot suggest which repairs the seller should make, what concessions the buyer should press for, or whether a particular inspection finding is a dealbreaker.
The agent can still handle paperwork, coordinate scheduling, make sure required property disclosures get completed, and pass offers and counteroffers back and forth without commentary. The agent also keeps a duty to be honest with both parties and to disclose known material facts about the property, such as structural problems or water damage. An agent who knows the roof leaks cannot hide that from the buyer just because the seller is also a client.
Written Consent Is Required
Dual agency cannot happen without both parties signing off. Every state that permits it requires informed, written consent from both the buyer and the seller. Verbal agreement is not enough, and consent cannot be buried in fine print or implied from the circumstances.
The National Association of REALTORS also requires its members to fully disclose the arrangement and obtain informed consent before proceeding, and to warn clients about the possibility of dual agency when the listing or buyer representation agreement is first signed.1National Association of REALTORS. 2026 Code of Ethics and Standards of Practice
The typical trigger: you are working with an agent to find a home, and you want to make an offer on a property that your own agent, or a colleague at the same brokerage, has listed. At that point, the agent must present the consent form before negotiations begin. If either party declines, the representation has to be restructured.
The form itself, usually titled something like “Consent to Dual Agency” or “Dual Agency Disclosure,” spells out the modified role and the specific duties the agent can no longer perform. By signing, you acknowledge that you will not get the full loyalty, advocacy, and strategic advice a dedicated agent would provide. Read it as a decision, not a formality.
The Commission Incentive
In a typical sale, the total commission is split between the buyer’s agent and the seller’s agent. When one agent handles both sides, that agent collects both portions. On a $400,000 home with a 5% total commission, that is the difference between splitting $20,000 and keeping all of it.
That financial pull is why the consent requirement exists. Some agents voluntarily reduce their total commission when acting as a dual agent, but it is not automatic. If you agree to dual agency, negotiating a lower combined rate is one of your few remaining leverage points, and the agent is saving the effort of coordinating with a counterpart, so a reduction is a reasonable ask.
Why Buyers Usually Lose More
On paper, dual agency disadvantages both sides equally. In practice, buyers tend to lose more. Sellers have already set their price expectations and the property is already listed. Buyers are the ones who need active guidance: what to offer, how to read an inspection report, whether the asking price matches the market, when to walk away. All of that advice disappears under dual agency.
A seller’s agent normally works to get the highest price. A buyer’s agent normally works to get the lowest. When those roles merge, the agent’s path of least resistance is whatever closes the deal fastest, which usually means the buyer pays more than they might have with independent representation. No agent will coach you through a lowball strategy when the seller is also their client.
First-time buyers are especially exposed. They are less likely to know what to ask, less familiar with local market conditions, and more dependent on the agent’s judgment. Agreeing to dual agency in that position means giving up the help you need most.
Alternatives Worth Considering
Designated Agency
The most common alternative is designated agency, sometimes called appointed agency. The brokerage still touches both sides, but the managing broker assigns two separate agents within the firm to represent the buyer and seller individually.2National Association of REALTORS. Vocabulary: Agency and Agency Relationships Each designated agent owes full fiduciary duties, including loyalty, confidentiality, and advocacy, to their own client. You get a real advocate even though the commissions flow through the same brokerage.
It is not perfect. The two agents share an office, a broker, and possibly information systems. But each agent can actually advise their client on strategy, pricing, and negotiation, which is a meaningful step up.
Transaction Brokerage
In some states, an agent can act as a transaction broker: assisting both parties with the mechanics of the deal without representing either one. There is no fiduciary relationship, no advocacy, and no loyalty to either side. The broker handles paperwork, coordinates timelines, and presents offers without weighing in on whether they are good or bad.
This is how several states that ban dual agency still let a single brokerage facilitate a deal. The difference from dual agency is transparency: no one is pretending to represent you, and the limited role is stated up front.
Saying No
You can always decline. If either the buyer or the seller refuses dual agency, the representation for that transaction has to be restructured, which usually means one party finds an agent at a different brokerage. On a high-value purchase, where the cost of weak representation runs into tens of thousands of dollars, this is often the cleanest option.
If Dual Agency Happens Without Your Consent
If an agent acts as a dual agent without obtaining proper written consent, the consequences are real. In most states that allow the practice, an undisclosed dual agent forfeits any right to a commission on the transaction. Either party can also seek to rescind the sale, meaning the deal can be unwound regardless of whether the agent acted in good faith.
Undisclosed dual agency is also grounds for discipline by state real estate licensing boards, with penalties that can include suspension or revocation of the license and civil fines. The agent may face a lawsuit for breach of fiduciary duty, which can produce damages beyond the lost commission.
If you find out after closing that your agent was quietly representing both sides, you likely have legal options. Talk to a real estate attorney promptly, because rescission deadlines vary by state.
