Dual Agency
A situation in which one agent or brokerage represents both the buyer and the seller in the same transaction, which limits full advocacy and requires informed consent where allowed.
The short answer
Dual agency is when one agent, or one brokerage, represents both the buyer and the seller in the same transaction. Where it is allowed, it requires informed written consent from both sides, and the agent can no longer advocate fully for either one.
Designated agency is the common alternative: the broker assigns one agent in the firm to the buyer and a different agent to the seller. Some states prohibit dual agency or use a transaction broker model instead, so check your state commission's agency rules.
| Arrangement | Who represents whom | Advocacy |
|---|---|---|
| Single agency | One agent or firm per side | Full advocacy for their own client |
| Dual agency | Same agent or firm for both sides | Limited: neutral on price and terms, with written consent |
| Designated agency | Same firm, different agents per side | Each agent advocates for their own client |
| Transaction broker | Facilitates the deal, represents neither side | No advocacy, only limited duties such as honesty |
Dual agency occurs when the same agent, or in some definitions the same brokerage, represents both the buyer and the seller in a single transaction. It creates an inherent tension: full fiduciary loyalty to two parties with opposing interests in price and terms is not simultaneously possible, so the agent's role is necessarily limited. Some states permit dual agency with the informed written consent of both parties, some permit modified forms such as designated agency, where different agents within one brokerage represent each side, and some prohibit it outright.
New agents encounter this issue sooner than they expect, often the first time a buyer calls about the agent's own listing. Understanding dual agency matters because handling it badly is one of the fastest ways to draw a complaint: you must recognize when a dual agency situation is forming, stop and disclose before continuing, and understand exactly which duties you can still perform and which you cannot. It also matters for advising clients honestly, since consenting to dual agency changes what representation they actually receive.
The rules here are strictly state-specific. Whether dual agency is legal, what disclosure and consent forms are required, when they must be signed, and whether designated agency or transaction brokerage are available alternatives are all defined by state law and your state real estate commission. Learn your state's required forms and timing cold before you are in the situation, and ask your sponsoring broker how the firm's policy handles in-house transactions, since brokerage policy is often stricter than the legal minimum.
Common questions
Is dual agency legal in every state?
No. Most states allow it with written consent, but some prohibit it or replace it with transaction brokerage or intermediary rules. Your state real estate commission publishes the agency relationships licensees may use.
What is the difference between dual agency and designated agency?
In dual agency one agent represents both sides, so they must stay neutral. In designated agency the brokerage appoints separate agents for buyer and seller, so each can advocate, although the broker above them still oversees both.
How does commission work in dual agency?
The brokerage may be paid for both sides of the sale. That is exactly why consent and disclosure are required: the agent has a financial reason to close the deal that is separate from either client's interest.
