Real Estate Agency Relationships in Missouri, Illinois, Kansas, and Arkansas

If you are buying or selling a home in the St. Louis Metro Area, the single most important thing to understand is this: who the agent represents, and what the agent can and cannot do for you.

Agency is not just paperwork. It affects price guidance, negotiation strategy, inspections, disclosure, and how protected you are when the deal gets tense. This page explains the main types of real estate agency available in Missouri, Illinois, Kansas, and Arkansas, the default relationship in each state, and the real-world pros and cons from the consumer side.

Quick Definitions (Plain English)

• Seller agency: the agent works for the seller and advocates for the seller.
• Buyer agency: the agent works for the buyer and advocates for the buyer.
• Dual agency: one brokerage (and sometimes the same agent) represents both buyer and seller in the same transaction, but with limited ability to advise either side.
• Transaction broker / transaction brokerage: the broker facilitates the deal but is not an advocate for either side.
• Customer or no agency relationship: the agent may handle clerical or basic transactional steps, but does not represent you as a client.

Missouri Agency Relationships (St. Louis City, St. Louis County, St. Charles, Jefferson, Franklin, and beyond)

Missouri is very clear on this point: unless there is a written agency agreement, the licensee is considered a transaction broker. That is the default relationship in Missouri.

• Default in Missouri: Transaction broker unless a written agency agreement exists. (MO Rev Stat 339.720)
• Common options: Seller's agent, Buyer's agent, Transaction broker, Dual agent (limited agent).

Missouri Seller's Agent

• Good for sellers because the agent is hired to promote the seller's interests.
• Watch-outs for buyers: If you are not represented, do not assume the listing agent is advising you.

Missouri Buyer's Agent

• Good for buyers because you get advocacy, strategy, and guidance.
• Watch-outs: Make sure the relationship is clearly documented in writing.

Missouri Transaction Broker

What it is: The broker helps facilitate the transaction but does not represent either side as an advocate.

Downside: When a real problem hits, people often expect advice and strategy.

Missouri Dual Agency (My opinion, and why it matters)

Dual agency is legal in Missouri, but it requires consent from all parties and the agent becomes a limited agent for both sides. (MO Rev Stat 339.750)

My take: Dual agency is often sold as smooth and efficient. It can be smooth right up until the moment you need real advice.

If you are unsure whether dual agency makes sense in your situation, ask me before you sign anything.
