2.4 Missouri Agency Relationships and Duties
Key Takeaways
- Missouri uses statutory LIMITED agency (RSMo 339.730-339.740), not common-law fiduciary agency — only the listed duties are owed
- Limited-agent duties to a client include loyalty, confidentiality, obedience to lawful instructions, disclosure of adverse material facts, accounting, and reasonable skill and care
- Confidentiality of a client's motivation, financial ability, and price limits survives termination of the relationship
- All licensees owe honesty, fair dealing, and disclosure of adverse material facts to ALL parties, even customers
- Agency arises only from a written brokerage service agreement; a licensee must disclose any personal interest in writing to all parties
Statutory Limited Agency (RSMo 339.730-339.740)
Missouri's most important agency concept is that the state replaced common-law fiduciary agency with statutory limited agency in 1996. A limited agent owes a client only the specific duties listed in RSMo 339.730-339.740 — nothing more is implied. This is why the exam refers to a dual agent as a 'limited agent' and why duties are narrower than the classic common-law list.
Limited-Agent Duties to a Client
| Duty | What it requires |
|---|---|
| Loyalty | Promote the client's interests; no undisclosed self-dealing |
| Obedience | Follow the client's lawful instructions only |
| Confidentiality | Protect client motivation, financial ability, and price limits |
| Disclosure | Reveal known adverse material facts and material information |
| Accounting | Account promptly for all money and property received |
| Reasonable skill and care | Perform competently and diligently |
Confidentiality Survives Termination
A licensee must keep confidential the client's motivation (why they buy or sell), financial ability (what they can afford), and any price the client will accept or pay — and this obligation continues even after the listing or buyer agreement ends. Disclosing a former seller-client's bottom line to a later buyer is a violation.
Client vs. Customer — the Decisive Distinction
| Term | Definition | Duties owed |
|---|---|---|
| Client | Party the licensee represents under a written agreement | Full limited-agency duties (loyalty, confidentiality, etc.) |
| Customer | Party NOT represented by the licensee | Honesty, fair dealing, disclosure of adverse material facts |
Every licensee owes every party — clients and customers alike — honesty, fair dealing, reasonable care, and disclosure of adverse material facts. The dividing line is that loyalty, obedience, and confidentiality are owed only to clients.
How Agency Is Created and Terminated
| Method to create | Effect |
|---|---|
| Written brokerage service agreement (listing / buyer agreement) | Creates the limited-agency relationship |
| Broker Disclosure Form | Informational only — creates nothing |
| Conduct or oral promise | Does not establish a written limited agency |
Agency can terminate by: completion of the transaction, expiration of the agreement term, mutual rescission, revocation by the principal, renunciation by the agent, or death/incapacity/bankruptcy of either party. Termination ends most duties but not confidentiality.
Personal-Interest and Designated-Agency Disclosure
A licensee who has a personal interest — buying or selling for their own account, a relative's property, or any profit interest — must disclose that interest in writing to all parties before contract. A designated broker may name a designated agent for a particular client so that other licensees in the firm are not automatically that client's agents, which is how Missouri firms avoid imputed firm-wide dual agency.
Worked scenario: A salesperson wants to buy a bank-owned listing personally. Before submitting the offer, they must disclose in writing to the seller that they are a licensed real estate agent acquiring for their own account. Trap: Believing that 'honesty to customers' is a lesser standard — it still bars affirmative misrepresentation and still requires disclosing adverse material facts.
Comparing the Four Missouri Relationships
The exam frequently presents a fact pattern and asks which relationship and duty set applies. Use this matrix:
| Relationship | Represents | Owes limited-agency duties? | Confidentiality |
|---|---|---|---|
| Seller's/landlord's agent | The seller/landlord | Yes — to that client | To the client |
| Buyer's/tenant's agent | The buyer/tenant | Yes — to that client | To the client |
| Disclosed dual agent | Both, with written consent | Limited; neutral | To both, no cross-disclosure |
| Transaction broker | Neither | No — neutral | Statutory neutral confidentiality |
Subagency Is Disfavored
Missouri's limited-agency law largely eliminated the old subagency trap where a cooperating broker automatically became the seller's subagent through the MLS. Today a cooperating broker who works with the buyer is typically the buyer's limited agent or a transaction broker, not the seller's subagent — unless a written subagency arrangement is expressly created.
Honesty to Customers Has Real Teeth
The customer relationship is not a license to mislead. To a customer a licensee must still:
- Refrain from any affirmative misrepresentation (active lie or concealment)
- Disclose adverse material facts known or that should have been known
- Treat the customer with honesty and fair dealing
- Account for any funds (such as earnest money) received
The distinction is only that loyalty, obedience, advocacy, and confidentiality are reserved for clients.
Putting It Together
Worked scenario: A buyer with no representation agreement asks a listing agent for advice on how low to offer. The agent — as the seller's limited agent — owes the buyer (a customer) honesty and disclosure of adverse material facts, but owes confidentiality and loyalty to the seller, so the agent must not coach the buyer to underbid. The agent should explain their seller-agency role (reinforced by the Broker Disclosure Form) and may suggest the buyer obtain their own representation.
Trap: A licensee who quietly advises the customer how to beat the seller's price has breached loyalty and confidentiality to the client and risks discipline under RSMo 339.100.
