2.2 Dual Agency and Transaction Brokerage
Key Takeaways
- A Missouri dual agent is a 'limited agent' who, with written consent of ALL parties, represents both sides of the same transaction (RSMo 339.710)
- Dual agency requires written informed consent obtained BEFORE the licensee begins acting as a dual agent
- A transaction broker is neutral, owes NO fiduciary/limited-agency duties, and serves as neither advocate nor advisor
- Confidential information learned before dual agency began stays confidential and may not be revealed to the other party
- Designated agency lets two licensees in the same firm each represent one side, avoiding firm-wide dual agency
Disclosed Dual Agency in Missouri
Under RSMo 339.710, a dual agent is a limited agent who, with the written consent of all parties to a contemplated transaction, has entered an agency brokerage relationship — not a transaction-brokerage relationship — and therefore represents both the seller and buyer (or landlord and tenant). The word limited matters: a Missouri dual agent owes only the statutory limited-agency duties, not full common-law fiduciary duties to either side.
When Dual Agency Arises
| Situation | Result |
|---|---|
| Same salesperson lists a home and also represents the buyer | Individual dual agency (consent required) |
| Two salespeople in one firm represent opposite sides, with no designated agency | Firm-level dual agency by imputation |
| Designated agents appointed for each side in one firm | NOT dual agency — each is a limited agent for one party |
The Consent Rule
Consent must be written, informed, signed by all parties, and obtained before the licensee begins acting as a dual agent. The disclosure must explain the limits on advocacy: the dual agent cannot negotiate for one side against the other and cannot reveal confidential information.
What a Dual Agent Can and Cannot Do
| Must do | Cannot do |
|---|---|
| Treat both parties honestly and fairly | Disclose one party's confidential financial limits |
| Disclose known adverse material facts | Reveal a party's negotiating strategy or motivation |
| Account for all funds and documents | Advocate for one party over the other |
| Follow lawful instructions of both | Recommend or suggest a specific price to either side |
Transaction Brokerage — the Neutral Alternative
Under RSMo 339.710, a transaction broker assists the parties without an agency or fiduciary relationship to either party and is therefore neutral, serving as neither advocate nor advisor. In Missouri, a licensee is presumed to be a transaction broker unless a written agreement establishes a different relationship — a default that frequently appears on the exam.
Dual Agency vs. Transaction Brokerage
| Feature | Dual Agency | Transaction Brokerage |
|---|---|---|
| Represents | Both parties (limited) | Neither party |
| Fiduciary/limited duties | Limited agency duties | None — neutral |
| Written consent | Required from all parties | Not required to establish (it is the default) |
| Advocacy | None (neutral between clients) | None (never a representative) |
| Confidentiality | Owed to both clients | Statutory confidentiality of specific facts |
Confidentiality Carryover
If a salesperson represented the seller as a single agent, then later both parties consent to dual agency, everything the agent learned as the seller's agent — the seller's bottom-line price, urgency, or financial pressure — remains confidential and may not be revealed to the buyer.
Worked scenario: A broker's two salespeople each have a signed agreement, one with the seller and one with the buyer, for the same listing. If the designated broker appoints each as a designated agent, the firm avoids dual agency entirely and each salesperson keeps full limited-agency duties to their own client. Trap: Failing to obtain written consent before acting, or revealing carried-over confidential information, exposes the licensee to MREC discipline under RSMo 339.100.
Designated Agency — Missouri's Preferred Solution
Missouri firms overwhelmingly use designated agency to handle in-house transactions instead of triggering dual agency. Under RSMo 339.820, the designated broker may appoint individual affiliated licensees as designated agents for particular clients. Each designated agent then owes full limited-agency duties to their own client, and the duties of one designated agent are not imputed to the other or to the rest of the firm.
| Model | Who represents whom | Confidentiality |
|---|---|---|
| Firm-wide dual agency | The whole firm represents both | Limited; agents neutral |
| Designated agency | One named agent per side | Full per client; not imputed firm-wide |
| Transaction brokerage | Neither party represented | Statutory neutral confidentiality |
Why it matters: In a designated-agency setup, the seller's designated agent can still advocate for the seller and the buyer's designated agent can still advocate for the buyer, even though both work under the same designated broker. Only the designated broker personally is treated as a dual agent or transaction broker for that file.
Statutory Confidentiality of a Transaction Broker
Even though a transaction broker is neutral, Missouri still imposes confidentiality of certain specific facts unless disclosure is authorized: a party's willingness to accept more or less than the asking/offering price, a party's motivation, and any information a party asks to be kept confidential — unless disclosure is required by law (for example, a known adverse material fact about the property) or is authorized in writing.
Disciplinary Exposure
Acting as a dual agent without written consent of all parties, or breaching the neutrality and confidentiality rules, is grounds for discipline under RSMo 339.100. The Commission can impose a civil penalty, suspension, or revocation. A licensee who 'helps both sides' informally without proper written disclosure has, in the Commission's view, performed undisclosed dual agency — a frequent complaint category.
Worked scenario: A buyer client falls in love with their own agent's listing. The agent may proceed only after both buyer and seller sign a written dual-agency consent, OR the designated broker appoints separate designated agents, OR the parties agree the licensee will act as a transaction broker. Simply continuing without any written instrument is a violation.
