Missouri Agency Law Guide

Agency law is among the most heavily tested topics on the Missouri real estate exam state section. Missouri's Brokerage Relationship Act creates a specific framework for how licensees must define and disclose their relationships with clients. Understanding this framework is essential for passing.

The Missouri Brokerage Relationship Act

Missouri's agency law is governed by the Brokerage Relationship Act (BRA), found within Missouri Revised Statutes Chapter 339. The BRA defines four types of brokerage relationships:

1. Seller's Agent The licensee represents the seller. All fiduciary duties run to the seller: loyalty, confidentiality, disclosure of material facts, obedience to lawful instructions, reasonable care, and accounting for funds. The seller's agent must disclose their agency status to buyers in writing.

2. Buyer's Agent The licensee represents the buyer. All fiduciary duties run to the buyer. The buyer's agent must disclose material facts about the property condition and market, protect the buyer's negotiating position, and avoid disclosing confidential buyer information to the seller.

Key Missouri distinction: Missouri does NOT require a buyer agency agreement to be in writing to be legally enforceable. This is different from many other states. The exam will test this.

3. Dual Agent When the same brokerage represents both buyer and seller in the same transaction, dual agency arises. Missouri allows dual agency only with the informed written consent of both parties. A dual agent cannot fully advocate for either client and must not disclose negotiating positions to either party.

4. Transaction Broker (Non-Agent) A transaction broker assists both parties without representing either. Transaction brokers owe honesty, competence, and proper handling of funds — but NOT full fiduciary duties to either party. Missouri permits transaction brokerage and it is an important part of the BRA.

Agency Disclosure Requirements

Missouri licensees must disclose their brokerage relationship status to prospective buyers and sellers at the first substantive contact — before any confidential information is exchanged. The disclosure must be made in writing.

The written disclosure must include: - The type of brokerage relationship being offered - A description of the duties owed under that relationship - A signature from the prospective client acknowledging receipt

Fiduciary Duties in Missouri

For licensees operating as agents (seller's or buyer's), the following duties apply:

  • Loyalty — Place the client's interest above all others, including the licensee's own interest
  • Confidentiality — Do not disclose information that could harm the client's negotiating position
  • Disclosure — Reveal all material facts known to the agent, including adverse property conditions
  • Obedience — Follow the client's lawful instructions
  • Reasonable Care — Perform with professional competence
  • Accounting — Properly handle and account for all client funds

Trust Account Handling

Trust fund handling is directly tied to fiduciary duty. In Missouri:

  • A salesperson who receives earnest money must deliver it to the broker by the next business day
  • The broker must deposit trust funds within the required period
  • Commingling trust funds with personal or operating funds is a license law violation
  • Records must be retained for 5 years

Designated Agency

When one brokerage represents both buyer and seller, Missouri law allows designated agency — assigning different salespersons from the same brokerage to each party. The designated agents act as full agents for their respective clients. The broker in the middle may technically be a dual agent, but the clients receive full representation from their designated agent.

Common Exam Traps

  • Forgetting that Missouri's BRA allows transaction brokerage (non-agency) — this is tested
  • Confusing dual agency (same agent) with designated agency (different agents, same brokerage)
  • Thinking Missouri requires a written buyer agency agreement (it does NOT)
  • Misapplying fiduciary duties: loyalty runs only to the client, not to all parties
