This guide is general legal information, not legal advice, and does not create an attorney–client relationship. Rules change and vary by state — verify current requirements with official sources or a licensed attorney.
Ask most buyers who their agent works for and the answer is instant: "me." Ask what document creates that relationship, what duties come with it, and what happens when the same brokerage also lists the house, and the answers get vague fast. Those are the questions that decide whether an agent must protect your confidences, disclose what they know, and put your interests ahead of their own commission.
Real estate licensing and agency are governed by state law, and the labels differ sharply. What one state calls a "transaction broker" another calls a "facilitator" or "non-agent"; some states permit dual agency with consent, and at least a few prohibit it outright for the same licensee. The framework below explains the concepts; your state's real estate commission and required agency disclosure form supply the specifics.
Key takeaways
- Agency is created by agreement — a listing agreement or a buyer representation agreement — not by who showed you the house.
- A true agent owes fiduciary duties: loyalty, confidentiality, disclosure, obedience to lawful instructions, reasonable care, and accounting.
- Dual agency means one licensee or brokerage represents both sides; it requires informed written consent where allowed, and it necessarily limits advocacy for each side.
- Agents share the seller's duty to disclose known material defects in most states, and federal lead-paint disclosure duties apply to agents directly for most pre-1978 housing.
- RESPA Section 8 bars kickbacks and referral fees for settlement services, which is why affiliated-business relationships must be disclosed.
Who represents whom
Agency law, as Cornell's Legal Information Institute puts it, is the common law doctrine controlling relationships between agents and principals: an agent who acts within granted authority binds the principal. Applied to real estate, that produces four common arrangements.
| Arrangement | Who the licensee represents | Practical effect |
|---|---|---|
| Seller's (listing) agent | The seller alone | Owes the seller full fiduciary duties; must still deal honestly with buyers |
| Buyer's agent | The buyer alone | Advises on price and terms, keeps buyer confidences, advocates in negotiation |
| Dual agent | Both parties, with consent | Cannot advocate price strategy for either side; confidentiality is limited by disclosure duties |
| Transaction broker / facilitator | Neither party as a fiduciary | Provides services and paperwork with honesty and fair dealing, but no loyalty duty |
The paperwork is what matters. A licensee who has not signed a buyer representation agreement with you may be working for the seller no matter how helpful they have been. Following industry-wide changes to brokerage practice that took effect in 2024, written buyer agreements before showings became standard across much of the market, and offers of buyer-broker compensation are no longer displayed in many multiple listing services. Compensation is now more explicitly negotiable and more explicitly documented — read what you sign about the amount, the term, and whether it survives if you buy through someone else.
What a fiduciary actually owes
Where a true agency relationship exists, the duties are demanding and are usually summarized in six categories:
- Loyalty. Put the client's interests ahead of the agent's own, including the agent's interest in closing a deal to earn a commission.
- Confidentiality. Do not reveal the client's motivation, walk-away price, or financial position, and in most states that duty continues after the transaction ends.
- Disclosure. Tell the client material facts the agent knows that affect the transaction, including a personal interest in the property or a relationship with the other side.
- Obedience. Follow lawful instructions — but not unlawful ones, which the agent must decline.
- Reasonable care and diligence. Exercise the skill of a competent licensee: accurate paperwork, timely delivery of offers, sound advice within the agent's expertise.
- Accounting. Handle earnest money and documents properly, with escrow and trust-account rules that are strictly enforced by state regulators.
Example (hypothetical): A buyer tells her agent she is willing to pay up to $560,000 but wants to open at $530,000. If the agent represents the buyer, repeating that ceiling to the listing side breaches confidentiality. If the same agent also represents the seller as a dual agent, the state's disclosure form likely says that price confidences are protected from both sides — meaning nobody gets negotiating help. That tradeoff is the point of the consent form.
Duties of competence have limits. Agents are not inspectors, appraisers, surveyors, engineers, or lawyers, and in most states they may not practice law by drafting custom contract language. A careful agent refers those questions out. When contract terms depart from the standard state form, the analysis belongs with counsel — an issue explored in our guide to residential purchase contracts.
Dual and designated agency
Dual agency arises when one licensee, or one brokerage, represents both buyer and seller in the same transaction. It is common in practice — in-house sales happen constantly — and it is legally awkward, because undivided loyalty to two opposed parties is impossible. States respond in three ways: permit it with informed written consent, permit only "designated agency" where the brokerage assigns different licensees to each side with internal firewalls, or prohibit it in specified forms.
Where it is allowed, the consent must be informed and is normally required in writing before it arises, not disclosed at the closing table. Consenting is not irrational: the same firm may have the best inventory or the best market knowledge. But go in understanding what you give up — advocacy on price and terms — and consider whether an independent adviser should review the deal.
Undisclosed dual agency is a different matter entirely. It is a serious licensing violation in most states and can support claims for breach of fiduciary duty, rescission of the agency agreement, or forfeiture of commission.
The disclosure duties agents actually carry
Three distinct disclosure obligations touch agents, and they come from different bodies of law.
Known material defects
Most states require sellers to complete a written property condition disclosure, and most also impose an independent duty on the listing agent to disclose material defects the agent actually knows about — even if the seller left them off the form. Some states extend the duty to defects a reasonably competent agent should have observed during ordinary inspection of accessible areas. What counts as material, and whether items such as a death on the property or nearby nuisances must be disclosed, is genuinely state-specific. Defect disputes that surface after closing often turn into the claims described in our guide to construction defects and homeowner remedies.
Federal lead-paint disclosure
For most housing built before 1978, the federal disclosure rule described by the EPA reaches agents directly: they must ensure the seller or landlord provides the "Protect Your Family From Lead In Your Home" pamphlet, discloses known lead-based paint and available records, includes a lead warning statement in the contract or lease, and gives buyers a 10-day window to conduct an inspection or risk assessment unless the parties agree otherwise. Signed disclosures must be retained for three years. Agents share responsibility for compliance, and penalties attach to violations. The same rule reaches rentals, which is why it also appears in our landlord–tenant guide.
Fair housing
The federal Fair Housing Act prohibits discrimination in the sale, rental, and financing of housing on the basis of protected characteristics, and enforcement is handled through HUD. For agents this bars refusing to show or sell, providing different service, and "steering" — directing buyers toward or away from neighborhoods based on protected characteristics — even when framed as helpfulness about "fit." Many states and localities add protected classes beyond the federal list.
Compensation, referrals, and the kickback rules
Commission is a matter of contract and is negotiable; nothing in law sets a customary rate, and agreements among competitors to fix rates raise serious antitrust problems. Two rules deserve attention beyond the percentage.
First, RESPA Section 8, implemented at 12 CFR 1024.14, prohibits giving or accepting any fee or thing of value for referring settlement service business, and prohibits charges for services not actually performed. The rule reaches beyond cash to discounts, marketing subsidies, and similar benefits tied to referrals, and regulators may treat a practice or course of conduct as an agreement. Bona fide compensation for services actually rendered, and cooperative brokerage fee splits, sit outside the prohibition — but the line is enforced.
Second, where an agent refers you to an affiliated title company, mortgage broker, or insurer, the affiliation must be disclosed and the use generally cannot be required. Shopping independently is your right; the CFPB's Owning a Home tools exist partly to make that comparison feasible. Closing-cost mechanics are covered in our guide to mortgages and settlement.
Frequently asked questions
Does the agent at the open house represent me?
Almost certainly not. An agent hosting a seller's open house is typically the listing agent, working for the seller. Anything you volunteer about your budget, urgency, or maximum price can be reported to the seller. Most states require an agency disclosure at first substantive contact — read it, and hold back negotiating information until you have your own written representation agreement.
Can I refuse dual agency?
Yes. Where dual agency requires informed written consent, you can decline and ask the brokerage to assign a different licensee under a designated-agency structure, or you can hire an independent agent. If a firm treats consent as a precondition to seeing a property, that is a business choice, not a legal requirement, and you may take your representation elsewhere.
What can I do if my agent breached a duty?
Three routes exist and they are not exclusive: a complaint to the state real estate commission, which can discipline or revoke a license; a claim through the brokerage or its errors-and-omissions insurer; and a civil suit for breach of fiduciary duty, negligence, or misrepresentation, where remedies can include damages or forfeiture of commission. Deadlines are state-specific and can be short, so get advice early.
Is the commission always paid by the seller?
No, and that has become more visible since the 2024 changes to brokerage practice. Compensation is negotiable and can be paid by the seller, by the buyer under a buyer representation agreement, or shared. What matters is what your written agreement says: the amount or rate, how it is earned, whether the seller's contribution offsets it, and how long the obligation lasts after the agreement ends.
Before you sign with an agent
Read three documents with the same care you would give the purchase contract itself: the state agency disclosure form, so you know whose side the licensee is on; the representation agreement, for its term, exclusivity, compensation, and any obligation that survives termination; and any affiliated-business disclosure, so you know where referrals lead. Ask directly how the firm handles in-house sales, because that answer tells you what happens if you fall in love with one of their listings.
Good agents welcome these questions; the arrangement is clearer for everyone when it is written down early. For the transactional and land-use context that surrounds representation, browse our real estate law section.
