The form of real estate agency that is illegal in most states where any agency type is prohibited is dual agency, the arrangement in which a single agent or brokerage represents both the buyer and the seller in the same transaction. Eight states ban it outright: Alaska, Colorado, Florida, Kansas, Maryland, Texas, Vermont, and Wyoming.1World Population Review. Dual Agency Legal States 2026 Every other state and the District of Columbia allow dual agency only under strict disclosure and written-consent rules, because the arrangement makes it nearly impossible for an agent to give either side the loyalty and confidentiality that normally come with representation.
What Dual Agency Is
Dual agency happens when one agent, or two agents working under the same brokerage, ends up on both sides of the same deal. The most common path there is simple. A buyer walks into an open house, likes the property, and asks the listing agent to write their offer. It can also occur when two agents at the same firm represent the buyer and seller separately, because the brokerage itself still represents both clients.
When you hire a real estate agent in a standard transaction, that agent becomes your fiduciary. They are legally required to put your interests ahead of everyone else’s, which is why the seller normally hires a listing agent and the buyer hires a separate buyer’s agent. Each side advocates for its own client. That adversarial structure is what keeps both parties protected.
Why This Is the Agency Type States Restrict
Dual agency is the arrangement states single out because the conflict of interest is built into it. One person now owes full fiduciary duties to two clients with directly opposing goals. The seller wants the highest price; the buyer wants the lowest. If the agent knows the seller would accept $20,000 less, they cannot share that with the buyer without harming the seller. If they know the buyer would pay $15,000 more, they cannot coach the seller to counter higher without harming the buyer. Loyalty and confidentiality become impossible to maintain on both sides at once.
The imbalance tends to fall harder on buyers. The listing agent already has an established relationship with the seller, knows the property’s history, and typically earns a percentage of the sale price, which rewards closing high. Buyers in a dual agency situation face several concrete risks:
- Weakened negotiation, because the agent cannot push hard on price for the buyer without undermining the seller, and details like the seller’s bottom line or urgency stay off-limits.
- Incomplete property information, because an agent who knows about issues may feel pressure to downplay them rather than torpedo the deal.
- A double-commission incentive, because the dual agent earns both sides of the fee and has a financial motive to close quickly rather than get either party the best outcome.
The Eight States That Ban Dual Agency Outright
In Alaska, Colorado, Florida, Kansas, Maryland, Texas, Vermont, and Wyoming, an agent cannot represent both sides of a transaction under any circumstances, no matter how clearly the parties consent. These states require agents to use a different structure, such as transaction brokerage or designated agency, that avoids placing one person in a position of conflicting loyalty. If you are buying or selling in one of these eight states, your agent is legally barred from also representing the other party.
How the Other 42 States and D.C. Regulate It
Everywhere else, dual agency is permitted but conditioned on consumer protections. The universal requirement is written disclosure and informed consent from both the buyer and the seller before the dual agency relationship begins.
Most states require agents to disclose their agency relationship at or before the first meaningful interaction about a property. The exact trigger varies. Some states specify first substantive contact; others tie it to the first showing, the first personal meeting, or the moment before an offer is drafted. The point is that you should know who the agent represents before you share any financial details or negotiating strategy.
When dual agency does arise in a state that allows it, both parties must sign a written consent form that explains what dual agency means and what each party is giving up. The agent’s role effectively shifts from advocate to neutral facilitator. They can share factual information about the property and handle paperwork, but they cannot advise either side on price strategy, negotiate aggressively for one party, or share confidential information one client disclosed. A dual agent still owes basic duties like honesty, fair dealing, and disclosure of material facts about the property’s condition. The full fiduciary duties of loyalty and confidentiality that come with exclusive representation are significantly watered down.
Consequences When Dual Agency Is Undisclosed
Practicing dual agency without proper disclosure is treated seriously whether a state allows the practice or bans it. State real estate commissions have the authority to suspend or revoke an agent’s license for acting as an undisclosed dual agent.2State of Texas. Texas Occupations Code 1101 – Section 1101.652 Beyond license discipline, undisclosed dual agency can give the harmed party grounds to rescind the contract, meaning the entire sale could be unwound. The agent may also forfeit their commission and face civil liability for any financial harm the client suffered because of the conflict.
If you discover after closing that your agent was also representing the other side without telling you, file a complaint with your state’s real estate commission and consult a real estate attorney about your options. The window for legal action varies by state, so moving quickly matters.
Legal Alternatives That Avoid the Conflict
Designated Agency
Designated agency, sometimes called appointed agency, is the most common alternative in states that allow it. When a buyer and seller are both clients of the same brokerage, the managing broker assigns separate agents to represent each side. Each designated agent owes full fiduciary duties to their own client, including loyalty and confidentiality.3National Association of REALTORS®. Vocabulary: Agency and Agency Relationships The brokerage must maintain information barriers so that confidential details about one client’s position don’t reach the other client’s agent.
It isn’t a perfect fix. Both agents still work for the same company, and the managing broker who appointed them has a relationship with both clients. But it provides far more protection than dual agency because each party has someone whose sole job is advocating for them.
Transaction Brokerage
Transaction brokerage removes the fiduciary relationship entirely. A transaction broker doesn’t represent either party. They serve as a neutral facilitator who handles paperwork, coordinates inspections and closing logistics, presents offers, and keeps the deal moving. They still owe honesty, fair dealing, and disclosure of known material defects. What they don’t owe is loyalty or confidentiality to either side, and they won’t advise you on what price to offer or whether to accept a counteroffer.
Several states that ban dual agency default to transaction brokerage as the standard relationship when an agent isn’t exclusively representing one party. Colorado and Florida both use this model. The important difference from dual agency is transparency: nobody is pretending to represent you while also representing the other side.
Protecting Yourself
Ask your agent directly who they represent before you share any financial information or discuss your negotiating strategy. Read the agency disclosure form carefully when it is presented to you. If the form says dual agent or transaction broker, understand that you don’t have someone in your corner the way you would with exclusive representation. You have the right to decline dual agency and find your own agent, even if it means walking away from a property you like.
If your agent asks you to sign a dual agency consent form mid-transaction, slow down. You are being asked to give up protections you started with. Get a second opinion or consult a real estate attorney before signing. The convenience of keeping the same agent rarely outweighs the cost of losing an advocate during the most expensive negotiation of your life.
