Key Takeaways

• California law permits dual agency — one real estate broker representing both buyer and seller — but only with informed written consent under California Civil Code sections 2079.13, 2079.14, and 2079.16.
• In a dual agency, each associate licensee under the same broker owes fiduciary duties to both principals, as established by the California Supreme Court in Horiike v. Coldwell Banker Residential Brokerage Co. (2016) 1 Cal.5th 1024.
• Dual agents cannot disclose price, motivation, or confidential strategy of one party to the other (Civil Code section 2079.21) — which significantly limits their ability to negotiate aggressively on either side.
• AB 2992 (Chapter 516, Statutes of 2024), effective January 1, 2025, requires written buyer-broker representation agreements, caps residential terms at three months, and prohibits automatic renewals — changing how buyer agency is documented in California.
• Buyers and sellers in high-stakes California transactions often retain their own attorney rather than relying on a dual agent, because an attorney can advocate aggressively for one side without the dual-agency conflict.

Dual Agency in California Real Estate: Risks Every Buyer and Seller Should Know

You toured the house with the listing agent. The conversation went well. The agent offered to write up your offer too — saving you the trouble of finding your own representation. Maybe a discount on commission was implied. The paperwork looks routine.

What you are stepping into is a dual agency. California law allows it, but only with informed written consent, and the dynamics are not what most buyers and sellers assume. This article walks through how dual agency works in California, what the agent legally can and cannot do, and where the real risks sit.

What dual agency is — and is not

California law uses specific terminology. The relevant Civil Code sections define:

• A “listing agent” — the agent representing the seller.
• A “selling agent” — the agent representing the buyer (or a dual agent representing both).
• A “dual agency” — the situation where the same broker represents both parties, often through different associate licensees within the same brokerage.

Dual agency in California is permitted under Civil Code sections 2079.13 and following sections, but it requires:

• Disclosure to both buyer and seller using the statutory Agency Relationship Disclosure (Form AD, codified text at Civil Code section 2079.16).
• Written confirmation of the agency relationship in or attached to the purchase contract under Civil Code section 2079.17.
• Informed consent from both principals.

Civil Code section 2079.18 separately prohibits the listing agent from also acting as the buyer’s exclusive agent in the same transaction without dual-agency consent. The framework reflects California’s longstanding policy of permitting dual agency only when both sides understand what they are giving up.

The Horiike rule: fiduciary duty to both sides

The California Supreme Court’s decision in Horiike v. Coldwell Banker Residential Brokerage Co. (2016) 1 Cal.5th 1024 clarified that when a single broker is a dual agent, each associate licensee under that broker owes fiduciary duties to BOTH the buyer and the seller — even when different agents within the same brokerage are working with the two sides.

This is a significant doctrine because it means an associate licensee working only with the seller still cannot ignore obligations to the buyer if the brokerage as a whole is in a dual agency. The associate cannot tell their seller “the buyer will go up” if they learned that information in confidence. They cannot advocate for the seller’s price position in a way that misleads the buyer. They cannot use information acquired through the dual agency to advantage one side over the other.

Horiike applies broadly. Even when buyer and seller appear to have “their own” agents, if both agents work for the same broker (the same brokerage), the brokerage is in a dual agency. The two agents may each feel like they are representing one side, but California law requires them to fulfill fiduciary duties to both.

What the dual agent cannot do

California Civil Code section 2079.21 prohibits a dual agent from disclosing certain confidential information without express consent:

• Disclosing to the buyer that the seller will accept a price less than the listed price (without seller authorization).
• Disclosing to the seller that the buyer will pay a price greater than the offered price (without buyer authorization).
• Sharing motivation, urgency, or other strategic information between the parties.

Practically, this means a dual agent cannot conduct the kind of aggressive negotiation that a single-side agent might. The dual agent has to remain neutral, which limits their effectiveness as an advocate for either party.

AB 2992: California’s new buyer-broker rules

AB 2992 (Chapter 516, Statutes of 2024), effective January 1, 2025, substantially changed how California buyer agency is documented. Key requirements:

• A buyer’s agent and a buyer must execute a written buyer-broker representation agreement no later than the execution of the buyer’s offer to purchase real property.
• Residential representation agreements are capped at three months.
• Automatic renewal of these agreements is prohibited.
• Agreements that violate the durational or renewal requirements are void and unenforceable.

AB 2992 was enacted in part as a response to industry changes following the Sitzer/Burnett antitrust settlement. The practical effect: California buyers should expect to sign a written buyer-broker agreement, and they should read it carefully. A buyer who signs without understanding the dual-agency exposure or the agent’s compensation structure may be giving up more than they realize.

Why buyers and sellers often hire their own attorney

In high-stakes California real estate transactions — luxury homes, complex commercial properties, family-related sales, transactions involving estate or trust issues — the limitations of dual agency often push parties toward independent attorney representation. A California real estate attorney can:

• Negotiate aggressively for one side without dual-agency conflicts.
• Advise on contract terms, contingencies, and risk allocation tailored to the client’s specific position.
• Review the dual agent’s disclosures and confirm that informed consent was obtained.
• Identify undisclosed conflicts and address them before closing.
• Coordinate with escrow, title, and the lender to ensure the client’s interests are protected at every step.
• Provide post-closing advocacy if problems emerge.

Bay Legal, PC’s transactional services are structured to provide this kind of representation for California buyers and sellers who want a clear advocate on their side, including in transactions where a dual agency is in place.

How dual agency affects price and terms negotiation

The structural neutrality of dual agency affects more than the agent’s behavior. Common practical consequences:

• Buyers in dual agency situations often pay closer to list price because the agent cannot help them craft a strategic low offer.
• Sellers in dual agency situations may leave money on the table because the agent cannot share their motivation or counsel against an early acceptance.
• Contingency periods, repair requests, and credit negotiations often resolve closer to the middle rather than favoring one side.
• When disputes arise, dual agents are typically less willing to advocate aggressively — they have ongoing obligations to both clients.

None of this means dual agency is inherently bad. For some transactions — especially smaller, less contentious deals between sophisticated parties — dual agency works well, can save commissions, and is straightforward. The issue is making an informed choice rather than drifting into dual agency without understanding the trade-offs.

Red flags worth pausing on

Some dual-agency situations warrant extra caution. Consider whether to consult an independent attorney if:

• The agent suggested dual agency rather than letting you choose.
• You have not seen and signed the Form AD agency disclosure.
• The compensation arrangement is unusual or unclear.
• The property is complex (HOA, condominium with SB 326 concerns, mixed-use, commercial).
• The transaction involves family members or close relationships.
• You feel pressure to remove contingencies before fully understanding what is in the disclosures.
• The agent’s behavior suggests they are emphasizing one side’s interests over the other.

Frequently Asked Questions

What is dual agency and is it legal in California?

Dual agency is when a single broker represents both the buyer and the seller in the same California real estate transaction. It is legal under Civil Code sections 2079.13 through 2079.18, but only with full disclosure and informed written consent from both parties.

What are the risks of using the seller’s agent as your buyer’s agent?

The agent cannot advocate aggressively for either side because they owe fiduciary duties to both. Confidential information is restricted. Negotiation tends to resolve closer to list price. And if conflicts arise, the agent often cannot meaningfully take a position. For high-stakes transactions, independent representation usually serves both buyer and seller better.

What disclosures is a dual agent required to make in California?

California Civil Code section 2079.14 requires delivery of the statutory Agency Relationship Disclosure (Form AD), with the text codified at Civil Code section 2079.16. Confirmation of the agency relationship in or attached to the purchase contract is required under Civil Code section 2079.17. After AB 2992, buyer-broker representation agreements are required and must comply with new durational and renewal limits.

When should you hire your own attorney instead of relying on a dual agent?

Strongly consider independent representation for high-value transactions, complex properties (HOA, condo, commercial, mixed-use), transactions with family or close relationships, or any situation where you want a clear advocate rather than a neutral facilitator. A California real estate attorney can negotiate without dual-agency constraints.

Does dual agency affect your ability to negotiate price or terms?

Yes. The dual agent cannot disclose confidential information that would advantage one side over the other, which limits aggressive negotiation. Many buyers and sellers in dual agency situations end up closer to middle-ground outcomes — sometimes favorably, often not.
