Yes, a real estate agent can get a commission after the contract expires. The usual mechanism is a broker protection clause written into the original listing agreement, which lets the agent claim a commission if you sell to a buyer they introduced during the listing period, provided the sale falls within a defined window after expiration. Whether the agent actually collects depends on the contract’s language, the type of listing you signed, and whether the agent can show they were the reason the buyer bought.
The Broker Protection Clause
The broker protection clause, sometimes called a safety clause or tail provision, is the tool agents rely on for post-expiration commissions. The rule it sets is simple: if you sell to a buyer the agent introduced while the listing was active, you owe a commission even after the listing ends, so long as the sale closes within the protection window.
National Association of REALTORS® policy requires that any protection clause in a standard MLS listing form leave the time period blank and negotiable between the seller and the listing broker, rather than locking in a preset duration.1National Association of REALTORS®. Current Listings, Section 17: Protection Clauses in Association MLS Standard Listing Contracts (Policy Statement 7.37) In practice, most protection periods run between 30 and 90 days, though some agents push for longer. The duration is one of the most important terms in the agreement, and it is fully negotiable before you sign.
The Protected Buyer List
For the clause to work, the agent typically has to hand over a written list of the specific buyers they introduced during the listing period. The list names the people the agent showed the property to or brought into negotiations. If a buyer is not on that list, the agent generally cannot claim credit for that buyer’s later purchase.
Delivery deadlines vary by contract, but many agreements require the agent to provide the list within a few days of expiration or termination. Miss that deadline and the agent’s protection rights can fall away entirely, regardless of how much work went in. If you are the seller, ask for the list promptly when the contract ends and keep it on file.
How Your Listing Type Changes the Answer
Not every listing agreement gives an agent the same footing after expiration. The type you signed sets the starting position.
- Exclusive right to sell. The agent earns a commission no matter who finds the buyer, even if you find them yourself. This is the most common arrangement and gives the strongest basis for a post-expiration claim.
- Exclusive agency. The agent is the only one authorized to market the property, but you can sell to a buyer you found on your own without owing a commission. The protection clause still applies to buyers the agent introduced.
- Open listing. You can hire multiple agents at once, and only the one who actually brings the buyer earns a commission. Post-expiration claims here rise or fall almost entirely on whether the agent can prove they were the reason the sale happened.
Procuring Cause: Who Actually Earned It
When there is no protection clause, when the window has passed, or when two agents both claim credit for the same buyer, the fight turns on procuring cause. The NAR defines it as “the uninterrupted series of causal events which results in the successful transaction,” with a successful transaction meaning a sale that actually closes.2National Association of REALTORS®. Appendix II to Part Ten – Arbitration Guidelines
Arbitration panels and courts weigh the full picture, not any single factor. The NAR’s guidelines highlight several considerations that come up repeatedly:
- Who made first contact. Which agent first introduced the buyer to the property, and whether the buyer already knew about it before any agent was involved.
- Ongoing relationship. Whether the agent maintained reasonable contact with the buyer or let the relationship go cold.
- Abandonment. Whether the agent’s inactivity gave the buyer reason to think the agent had disengaged from the deal.
- Estrangement. Whether the agent’s own conduct pushed the buyer toward someone else.
- Continuity of events. Whether the agent’s introduction started an unbroken chain leading to closing, or a second agent’s separate effort produced the sale.
The NAR guidelines explicitly reject rules of thumb and predetermined formulas. Each case is judged on its own facts.2National Association of REALTORS®. Appendix II to Part Ten – Arbitration Guidelines An agent who showed the property once and then vanished for two months sits in a far weaker spot than one who stayed in regular contact, answered questions, and kept the deal moving.
Documentation carries the argument. Agents protecting a post-expiration claim need emails, text messages, showing records, and notes from conversations. Without a paper trail, procuring cause claims collapse quickly no matter what actually happened.
Avoiding Two Commissions on the Same Sale
One of the worst surprises for a seller is finding out they owe commissions to two different agents on one sale. This happens when the original agent’s protection period overlaps with a new listing signed with another broker. If the first agent introduced the buyer but the sale closes under the second agent’s listing, both may have grounds to claim a commission.
Most listing agreements handle this with a carve-out: the original agent’s protection clause does not apply if you sign a new exclusive listing with a different broker. The logic is that you should not owe two full commissions on the same sale. But the carve-out is not universal, and its exact wording matters. Some contracts require the new listing to be truly exclusive to trigger the exception. Others do not include the exception at all. Even where the carve-out applies, the first agent may still have a procuring cause claim against the new listing broker’s share of the commission.
Two practical steps head off the trap. Get the protected buyer list from your previous agent when the contract ends. Then share it with your new agent and have any overlapping buyers addressed in the new listing agreement, either through an exclusion list naming buyers who will not count toward the new agent’s commission, or through a clear allocation of who gets paid if one of those buyers ends up purchasing.
What If You Never Signed a Written Agreement
Every state has adopted some version of the statute of frauds, which generally requires real estate contracts to be in writing to be enforceable. Listing agreements and commission contracts fall under that rule. An agent with no signed agreement faces a steep climb collecting a commission, because most courts will not enforce an oral promise to pay a real estate commission.
A narrow exception exists. Under quantum meruit, an agent who provided valuable services that the seller accepted may recover the reasonable value of those services even without an enforceable written contract. Courts have allowed this where the agent did substantial work, the seller benefited, and refusing payment would be fundamentally unfair. These claims are hard to win precisely because the statute of frauds exists to prevent exactly this kind of dispute. A seller who never signed anything has a strong defense; an agent who worked without a signed agreement took a known risk.
The takeaway runs both directions. A verbal arrangement does not fully shield a seller, because some courts will still hear a quantum meruit argument. And no agent should start work without a signed agreement, because oral commission promises are difficult to enforce.
Check Whether the Contract Actually Expired
Some listing agreements include automatic renewal or “evergreen” clauses that extend the contract indefinitely unless the seller affirmatively cancels. These clauses effectively prevent the listing from ever truly expiring, which removes the post-expiration question by keeping the agent under contract. A growing number of states either prohibit or restrict automatic renewal in residential listing agreements, but the language still shows up. Before you assume your contract is over, read the termination clause and confirm what you had to do to end it.
Protecting Yourself Before You Sign
The protection clause is where sellers have the most leverage, and the time to use it is before signing. A few habits keep a surprise commission bill from landing months after you thought the relationship ended.
- Negotiate the protection period up front. NAR policy requires this term to be negotiable, not preset. If an agent asks for 180 days, push back. A 30- to 45-day window is common and reasonable for most residential sales.1National Association of REALTORS®. Current Listings, Section 17: Protection Clauses in Association MLS Standard Listing Contracts (Policy Statement 7.37)
- Demand the protected buyer list in writing. When the listing expires, ask for the list of buyers the agent claims to have introduced. If the contract sets a delivery deadline, hold the agent to it.
- Share the list with your next agent. If you plan to relist, give the new broker the previous agent’s protected buyer list. Build an exclusion clause into the new agreement so you know exactly who triggers a commission obligation, and to whom.
- Check for automatic renewal language. Read the termination clause carefully. If the agreement renews on its own, negotiate the provision out or calendar the cancellation deadline so you do not miss it.
- Keep your own records. Save emails, showing confirmations, and written communication with the agent. If a dispute comes up, your records matter as much as theirs.
An agent who invested real time and effort in marketing your property deserves to be paid for the results they produced. The terms of that payment should be clear from the start, not discovered later in fine print you never focused on. Read the protection clause, negotiate its length, and know exactly what happens the day the listing ends.
