What Is Limited Dual Agency in Washington?
Limited dual agency is when one brokerage — or one agent — works both sides of a deal. It's legal in Washington with written disclosure. Here's what you give up.
Limited dual agency is when the same agent — or two agents at the same brokerage — represents both the buyer and the seller in one transaction. It’s legal in Washington, but only with written disclosure and the parties’ consent, and the word “limited” is doing the real work: a dual agent legally cannot give either side the full loyalty a normal agent owes. They become a neutral facilitator of the deal rather than your advocate in it.
Why this arrangement exists
Brokerages are big, and deals are local. The same office that listed a Wallingford craftsman often also has a buyer’s agent with a client who wants it — and sometimes the listing agent personally meets an unrepresented buyer at the open house who says “can you just write it up?” Banning that outright would unwind a lot of deals, so Washington’s agency law takes the disclosure route instead: dual agency is permitted, but the limitation on loyalty must be put in front of you in writing, and you must agree to it.
The honest framing: dual agency exists primarily because it’s convenient and lucrative for the brokerage side, not because it serves consumers. When one agent handles both sides, both halves of the commission can land in one place.
The two flavors, and why the difference matters
- Same brokerage, different agents. Your agent and the other side’s agent share a company. The designated-agent structure means each of you still has your own advocate day to day; the firm is the dual agent. This version is common and, in practice, usually low-drama.
- Same individual agent, both sides. One human represents the buyer and the seller in the same negotiation. This is the version that should make you slow down, because the conflicts aren’t theoretical: that agent knows your maximum and the seller’s minimum, and owes full loyalty to neither of you.

What you actually give up
A dual agent can still do the mechanical work: write the contract, hit the deadlines, coordinate escrow and inspections. What they can’t do is the judgment work you hired an advocate for:
- They can’t tell the buyer “offer less — the seller’s desperate,” or tell the seller “hold firm — this buyer loves the house.”
- They can’t share either side’s confidential price tolerance.
- Their incentive tilts toward the deal closing, which is not always the same as your best deal.
The most common harm isn’t dramatic betrayal; it’s a quiet shading of advice toward whatever keeps the transaction alive — the same conflict-of-interest gravity that runs through commission-paid representation generally, concentrated into one person.
What to actually do if it comes up
- Read the agency disclosure, don’t just sign it. Washington requires the limitation to be disclosed in writing. That paper is your cue to ask: who exactly represents me, and what can’t you tell me anymore?
- You can say no. Consent is required. You can ask for a different agent in the same brokerage, or bring your own representation.
- If you proceed, negotiate the fee. A dual agent doing half the advocacy for double the commission share is a fair thing to push back on. Asking for a meaningful fee reduction in a dual-agency deal is reasonable, and commissions are negotiable in Washington — full stop.
- Lean harder on the objective record. With no advocate interpreting for you, the Form 17 disclosure, the inspection, and a solid CMA become your real protection.
