Dual agency is bad because one agent, or one brokerage, cannot genuinely represent both the buyer and the seller in the same deal. The moment the same person sits on both sides of the table, the duties that make an agent useful — loyalty, confidentiality, strategic advice, and the obligation to put your interests first — are stripped down to a neutral facilitator role. You keep paying for representation, but you stop receiving it.
The Agent Gets Paid Twice to Not Take Sides
A seller wants the highest price. A buyer wants the lowest. There is no way to fight for one without hurting the other, so a dual agent’s only lawful move is to stop fighting for either. That is the structural problem, and it exists regardless of how honest or well-intentioned the individual agent is.
The money makes it worse. Total real estate commissions now average roughly 5% to 5.5% of the sale price, typically split between a listing agent and a buyer’s agent. A dual agent handling both sides of a $500,000 sale could collect the entire commission, around $25,000 to $27,500, instead of the $12,500 to $13,750 they would earn on one side. That is a strong incentive to keep the deal together rather than push for a better number for you.
Following the nationwide settlement with the National Association of Realtors that took effect in August 2024, buyers now typically negotiate their own agent’s compensation in writing before touring homes. In a dual agency setup, that negotiation is happening with the same agent who is also being paid by the seller — another layer of conflict baked into the paperwork.
You Sign Away the Duties You Hired an Agent For
A dedicated buyer’s agent or listing agent owes you fiduciary duties: loyalty, confidentiality, full disclosure, obedience to your lawful instructions, and the obligation to act in your best interest above their own. Those duties are the whole point of hiring an agent.
Dual agency removes most of them. Before an agent can represent both sides, both parties must sign a written consent form acknowledging that the agent can no longer advocate exclusively for either one. The NAR’s 2026 Code of Ethics requires “full disclosure to and with informed consent of both parties” before any agent may represent both buyer and seller in the same transaction.1National Association of REALTORS®. 2026 Code of Ethics and Standards of Practice Once signed, the agent shifts from advocate to neutral facilitator, and the duty of undivided loyalty effectively disappears.
Many consumers sign without understanding what they are giving up. The legal language is dense, and the person handing it to you has a direct financial reason to keep both parties in the deal. Read the form as a list of protections you are agreeing to lose, not as a routine formality.
No Advice on Price, No Advice on Terms
The most immediate loss is pricing guidance. A dual agent cannot tell a buyer the home is overpriced, suggest offering less than asking, or point out that comparable properties sold for significantly less. The agent also cannot advise a seller to reject a low offer, push for a higher counter, or hint that a buyer has room in their budget to pay more.
Every other negotiable term carries the same restriction. Inspection repair requests, financing contingencies, closing cost credits, move-in timelines — each requires strategic judgment, and the agent is barred from providing it to either side. Advising one party on which concessions to grant or demand would, by definition, hurt the other.
So you end up making six-figure decisions on your own market read. A first-time buyer may not realize the seller already dropped the price twice and is clearly flexible. A seller might accept terms that leave thousands on the table. The agent typically knows these things and legally cannot use them to help you.
Your Confidential Information Is Not Really Confidential
Agents learn sensitive things in the normal course of the job: a seller’s divorce forcing a quick sale, a buyer’s maximum pre-approval amount, a willingness to accept less or pay more than the stated number. Under dual agency, the same person holds those details for both sides and is prohibited from sharing them without written permission.
The categories a dual agent must keep confidential include each party’s financial position, motivations, bargaining position, and personal details that could move the price. The agent cannot reveal a seller’s willingness to accept less than list, or a buyer’s willingness to pay more than offered. An offhand remark or even a facial expression during negotiations can function as an implied disclosure that shifts leverage.
At the same time, the agent still has an independent duty to disclose material defects about the property. If they know about a foundation issue the seller has not mentioned, they must tell the buyer, even though that hurts the seller. The competing obligations create constant tension, and a single misstep can trigger legal liability and state licensing discipline.
When Two Agents in the Same Office Share One Deal
Dual agency does not only mean one agent showing their own buyer their own listing. It also arises when two agents from the same brokerage end up on opposite sides of the same transaction. Both commissions flow through the same managing broker, so the brokerage itself becomes a dual agent even if the individual agents think of themselves as independent.
Many states address this through “designated agency,” where the managing broker appoints one agent to represent the seller and another to represent the buyer. Designated agents give their clients full representation with fiduciary duties intact, which avoids the reduced-duty problem of standard dual agency.2National Association of REALTORS®. Vocabulary: Agency and Agency Relationships The managing broker, though, remains a dual agent and must keep confidential information from leaking between the two files.
In practice, designated agency has real limits. The agents share an office, a managing broker, and often a team brand. The information barrier depends on office discipline, not physical separation. If the managing broker directly supervises one of the designated agents, as with a newly licensed agent, that broker may still see both sides’ confidential details. If you work with a large team or brokerage, ask early how the firm handles situations where another agent in the office has the other side of a deal you want.
Some States Have Banned It
Roughly eight states have decided the conflicts are too severe to manage through disclosure and have banned dual agency outright. In those states, when a situation would otherwise create dual agency, the agent must shift to a “transaction broker” or similar non-agent role rather than represent both sides.
A transaction broker handles the paperwork and logistics without representing either party in a fiduciary capacity. The limited duties owed are honesty, fair dealing, accounting for funds, disclosure of known property facts, and presenting all offers and counteroffers. What is missing: loyalty, obedience, and the obligation to put either party first. Some consumers assume a transaction broker is “their” agent; legally, the relationship is much thinner than that.
In states that still allow dual agency, proceeding without proper disclosure can carry severe consequences, including rescission of completed sales, commission forfeiture, and license suspension or revocation.
The Consent Form Is the Whole Ballgame
Where dual agency is permitted, it cannot proceed without written consent from both buyer and seller, obtained before the agent starts acting for both sides. The NAR Code of Ethics also requires agents to flag the possibility of dual agency at the outset of listing and buyer-representation agreements, so clients can think about it before a specific deal forces the issue.1National Association of REALTORS®. 2026 Code of Ethics and Standards of Practice
Agents accepting compensation from both parties must separately disclose that fact and obtain informed consent from each client.1National Association of REALTORS®. 2026 Code of Ethics and Standards of Practice If anything material changes after consent is given, the agent must re-disclose and give both parties a fresh chance to revoke. Signing the form unread, or under time pressure at an open house, is one of the most common ways people quietly give up full representation.
How to Protect Yourself
The simplest protection is to hire your own independent agent from a different brokerage. Separate representation gives each side an advocate with no conflicting obligations, and in most transactions it costs you nothing extra, since commissions are negotiated independently.
If dual agency is already on the table and you are deciding whether to proceed, these steps limit your exposure:
- Negotiate the commission down. A dual agent is collecting from both sides with no cooperating broker to split with. Many will agree to a reduced total, sometimes from the typical 5% to 5.5% range down to 4% or less. Ask before signing anything.
- Hire a real estate attorney. An attorney owes you undivided loyalty and can review the contract, advise on price, and flag unfavorable terms, which are exactly the things the dual agent cannot do. The fee is usually a fraction of what a bad deal costs.
- Get an independent appraisal or comparative market analysis. Since the dual agent cannot tell you whether the price is fair, pay for your own valuation. That gives you the market data the agent is barred from interpreting for you.
- Read the consent form line by line. Treat it as a contract that removes your protections, because that is what it is. If a provision is unclear, ask for a written explanation or run it past an attorney first.
- Put everything in writing. Accidental disclosures can shift bargaining power and create disputes later, so keep communications about price, terms, and contingencies in channels you can document.
Dual agency is one of the few places in real estate where the person you are paying to help you is legally barred from fully doing so. The time to weigh that tradeoff is before you sign the consent form, not after.
