A realtor can sue for commission when there’s a signed written agreement entitling them to compensation and they performed the work that agreement required. In practice, the suit is filed by the agent’s brokerage rather than the agent personally, and whether it succeeds turns on the specific language of the listing or buyer-broker agreement, proof that the agent held a valid license at the time, and evidence the agent actually did the work.
You Need a Written Agreement
No writing, no lawsuit. Nearly every state requires real estate commission agreements to be in writing under the statute of frauds. An oral promise to pay a commission is virtually unenforceable, no matter how clear the handshake felt. A court will not entertain testimony about a verbal deal that was never put on paper.
For sellers, the controlling document is the listing agreement between the seller and the brokerage. It sets the commission rate, the listing period, and what the agent is expected to do. Commissions are fully negotiable and are not set by any law or industry rule.1National Association of REALTORS®. Compensation, Commission and Concessions For buyers, the equivalent is a buyer-broker agreement covering the agent’s compensation and scope of representation. One of these documents is the contractual foundation of any commission suit.
Since the NAR settlement took effect in August 2024, any agent working with a buyer must sign a written agreement with that buyer before touring a home, and the agreement must state the specific amount or rate of compensation in a way that’s objectively measurable and not open-ended.2National Association of REALTORS®. NAR Settlement FAQs For buyer’s agents, that requirement is helpful in a dispute: every represented buyer now has a signed fee agreement that can support a breach-of-contract claim.
Listing agreements usually include a protection clause (sometimes called a safety clause or tail provision). It gives the agent a window after the listing expires to still collect a commission if the property sells to a buyer the agent introduced during the listing period. Protection periods typically run 30 to 90 days and are negotiable. Without that clause, a seller could wait out the listing and sell to the agent’s buyer the next day without owing anything.
When the Commission Is Legally Earned
There’s a meaningful difference between when a commission is earned and when it gets paid. Under the traditional rule, the agent earns the commission the moment they produce a “ready, willing, and able” buyer, meaning a buyer who wants to purchase on the seller’s terms and has the financial capacity to close.3Legal Information Institute. Ready, Willing, and Able If the seller then gets cold feet and walks away from a full-price offer, the agent has still performed and the commission is owed.
Many modern listing agreements override that default by tying payment to the actual closing and funding of the sale. Under that language, no closing means no commission, regardless of how qualified the buyer was. The specific words in the agreement decide which rule applies, which is why any agent who wants the stronger “ready, willing, and able” protection has to negotiate for it before signing.
Situations That Commonly Produce Lawsuits
The Seller Backs Out After Accepting an Offer
An agent finds a qualified buyer, the seller accepts, then the seller changes their mind. If the listing agreement uses the “ready, willing, and able” standard, the brokerage can sue for the full commission whether or not the sale closed. If the agreement conditions payment on closing, the claim is weaker, though the brokerage can still argue the seller breached the listing agreement by refusing to perform.
A Post-Expiration Sale to the Agent’s Buyer
This is exactly what the protection clause covers. A seller lets the listing lapse and quietly sells to someone the agent had shown the property to weeks earlier. To win, the brokerage has to show the buyer was introduced during the listing period and the sale closed within the protection window. Most listing agreements require the agent to submit a written list of buyers they introduced, and that list is the core evidence when this dispute arises.
The Seller and Buyer Cut the Agent Out
Sometimes a seller and buyer decide to save money by closing without the agent. If the agent originally introduced the buyer, that’s a clear breach of the listing agreement, and the brokerage can sue the seller for the commission. In some jurisdictions the agent may also have a claim against the buyer for tortious interference, though those claims are harder to prove and less commonly pursued.
Two Agents Claim the Same Commission
When a listing agent and a buyer’s agent both claim credit, the dispute is decided under the “procuring cause” doctrine: the agent whose efforts set off the unbroken chain of events leading to the sale is the one entitled to the commission. Simply showing a house once isn’t enough. If the buyer went silent for months and closed later through a different agent, the first agent’s claim is thin. Documentation wins these fights, so emails, texts, showing confirmations, and call notes matter more than memory.
For REALTORS who belong to an NAR-affiliated board, this kind of dispute doesn’t go to court. NAR’s Code of Ethics requires members to submit commission disputes with other REALTORS to mediation and, if that fails, binding arbitration through the local board.4National Association of REALTORS®. Statements of Professional Standards Policy Applicable to Arbitration Proceedings A REALTOR who refuses to arbitrate faces board sanctions up to suspension or expulsion.
The Brokerage Sues, Not the Individual Agent
A detail many agents miss: in most states the individual salesperson doesn’t have standing to sue for a commission. The listing agreement is between the seller and the brokerage. The buyer-broker agreement is between the buyer and the brokerage. The commission is owed to the brokerage, which then splits it with the agent under their internal arrangement. If a commission goes unpaid, the brokerage is the plaintiff.
Licensing is a second threshold. If the agent wasn’t properly licensed at the time of the transaction, courts will throw the claim out as a matter of public policy. Even a strong case on the merits can fail because of an expired or invalid license during the listing period. Letting a license lapse mid-listing creates a problem no lawyer can fix later.
Arbitration May Be Required Before Court
Not every commission dispute can go straight to court. Many listing and buyer-broker agreements include arbitration clauses that require disputes to be resolved privately. Arbitration is usually faster and cheaper than litigation, but the decision is binding and appeals are extremely limited.
For disputes between REALTORS from different firms, NAR’s Code of Ethics makes arbitration mandatory through the local board rather than the courts.4National Association of REALTORS®. Statements of Professional Standards Policy Applicable to Arbitration Proceedings If the arbitration panel decides the dispute is too legally complex or involves too much money, it can release the parties to go to court. For disputes between an agent and a client, whether arbitration is required depends on what the signed agreement says. Check the agreement before assuming litigation is available.
Steps to Take Before Filing
A commission suit should be the last option, not the first. Start with a formal demand letter that identifies the contractual basis for the commission, the exact amount owed, and a deadline for payment. Reference the specific listing or buyer-broker agreement and state clearly that the brokerage will pursue legal remedies if the commission isn’t paid. That letter gives the other side a final chance to pay and creates a paper trail showing the brokerage tried to resolve the matter first.
Watch the clock. Every state sets a statute of limitations for breach-of-contract claims, and a written commission agreement falls squarely in that category. Most states allow between three and six years, though a handful go up to ten. Once the deadline passes, the claim is dead no matter how strong it was. The clock generally starts when the commission was due but went unpaid.
Pull the documentation together before calling a lawyer. The signed agreement is the centerpiece, but the supporting materials do heavy work: communications with the client, proof of the buyer’s qualifications, showing records, marketing efforts, and any written acknowledgment that the agent introduced the buyer. A strong paper trail also makes settlement more likely.
What the Brokerage Can Recover
The main remedy is the unpaid commission itself, calculated under the terms of the agreement. A 5% commission on a $400,000 sale means the brokerage is seeking $20,000.
Many real estate agreements include a prevailing-party attorney’s fees clause. When that language is present, a brokerage that wins can recover its legal costs on top of the commission. Without it, each side generally pays its own lawyer regardless of the outcome, which can make smaller disputes economically impractical to litigate. For lower-value commissions, small claims court may be an option; filing limits vary by state but generally fall between a few thousand dollars and roughly $10,000 to $20,000.
Where the seller’s conduct was particularly egregious, such as deliberately conspiring with a buyer to avoid the commission, the brokerage may also seek consequential damages beyond the commission itself. Those claims are harder to prove and less common, but they exist when a straightforward breach-of-contract recovery doesn’t fully cover the harm.
