5.1 Broker Responsibilities, Brokerage Agreements, and Compensation
Key Takeaways
- An exclusive right-to-sell listing pays the broker no matter who finds the buyer, while exclusive agency lets the owner sell directly without owing commission
- Missouri Rule 20 CSR 2250-8.090 prohibits net listings
- Procuring cause, not who held the listing, decides which broker earned a contested commission
- Commission is always negotiable; agreeing on rates with competing firms is illegal price fixing
- The sponsoring broker supervises trust funds, advertising, and agents, and must avoid commingling client money with operating funds
Real estate practice rests on written brokerage agreements, supervision, and clear rules about who gets paid. The national exam tests these patterns heavily, so learn the agreement types and the compensation logic until they are automatic.
What the Supervising Broker Is Responsible For
Every salesperson works under a sponsoring broker (also called the designated or principal broker). That broker is legally accountable for the office, even for acts performed by salespeople. Core duties include:
- Supervising agents, listings, and negotiations
- Safeguarding client funds in a trust (escrow) account
- Reviewing advertising for accuracy and fair housing compliance
- Ensuring required disclosures are delivered on time
- Preventing the unauthorized practice of law (UPL)
UPL occurs when a licensee gives legal advice or drafts custom legal language instead of using state-approved forms. An agent may fill in blanks on an approved contract and explain what a clause does, but may not advise on the legal consequences of a deed or write new contract provisions.
The Four Listing-Agreement Types
A listing agreement is an employment contract between a seller and a broker. The differences come down to who may sell and who gets paid.
| Agreement | Who may sell | Commission owed? | Key feature |
|---|---|---|---|
| Exclusive right-to-sell | Broker, any cooperating agent, or the seller | Always, during the term | Broker is paid no matter who procures the buyer |
| Exclusive agency | Broker or the seller | Only if the broker (or a cooperating agent) sells | Seller may sell on their own with no commission |
| Open listing | Any number of brokers, or the seller | Only the broker who is procuring cause | Non-exclusive; brokers compete |
| Net listing | Broker | Broker keeps everything above the seller's net | Prohibited in Missouri under 20 CSR 2250-8.090 |
The exclusive right-to-sell is the most common because it gives the broker the most certainty and therefore the most marketing effort.
Exam trap: In a net listing the seller names a net amount; the broker keeps any excess. This lets the broker keep all upside above the seller's fixed net and can obscure the size of the fee, so it is banned or tightly restricted.
Buyer and Property-Management Agreements
A buyer representation (buyer-broker) agreement establishes how a broker represents a buyer. It states the scope of services, the geographic area and term, how compensation is earned, and termination terms. Putting it in writing prevents an accidental implied agency.
A property management agreement authorizes a broker to lease and operate property for an owner. The manager screens tenants, collects rent, arranges maintenance, and accounts for security deposits and owner funds, all while following fair housing and trust-account rules.
The Multiple Listing Service
The Multiple Listing Service (MLS) is a cooperative database where listing brokers share inventory and historically offered compensation to cooperating brokers. Following the 2024 NAR settlement, offers of compensation are no longer published in the MLS; commission is negotiated separately. Buyer-broker compensation is now typically addressed in the buyer agreement.
How Brokerage Agreements End
- Expiration of the stated term
- Full performance (a sale or lease closes)
- Mutual rescission by both parties
- Revocation by the principal or renunciation by the broker (may create liability)
- Death, incapacity, or destruction of the property
Compensation, Splits, and a Worked Example
Compensation is always negotiable and may be a percentage of price, a flat fee, or hourly/retainer. The seller, the buyer, or both can pay it, depending on the agreements signed. Commission is earned when the broker produces a ready, willing, and able buyer on the seller's terms, even if the seller then backs out.
Work the math step by step. Suppose a home sells for $420,000 with a 6% total fee, split 50/50 between the listing and selling sides. Each side's brokerage receives 0.06 x $420,000 / 2 = $12,600. If the selling salesperson is on a 70/30 split with their broker, the agent earns 0.70 x $12,600 = $8,820 and the broker keeps $3,780.
Procuring Cause
When two brokers each claim a commission, the question is procuring cause: which broker's unbroken efforts actually produced the ready, willing, and able buyer? Simply opening a door or sending one email rarely qualifies; an unbroken chain from first contact to contract usually does. MLS arbitration and the listing terms guide the split.
Trust Accounts and Common Pitfalls
Client money, earnest money, and deposits go into a separate trust/escrow account, never the broker's operating account. Mixing the two is commingling; using client funds for the broker's own purposes is conversion, a far more serious violation. Brokers reconcile these accounts regularly and keep records by transaction.
Frequent practice mistakes:
- Failing to document an agency relationship in writing
- Commingling earnest money with operating funds
- Giving legal advice instead of referring to an attorney
- Setting commission rates by agreement with competitors
Exam tip: A licensee should refer legal questions to an attorney, tax questions to a CPA, and structural questions to a licensed engineer or inspector. Staying within scope reduces liability.
Under which listing agreement may the seller sell the property without owing the broker a commission?
A home sells for $380,000 at a 6% total commission, split evenly between the listing and selling sides. The selling salesperson keeps 60% of their side. How much does that salesperson earn?
