Broker Commission Litigation

Decoupled Compensation, Durable Doctrine: Commission Claims After the NAR Settlement

The antitrust litigation that rewired broker compensation ended in a nationwide settlement, and the final-approval order is now the anchor document. Sitzer v. National Association of Realtors, No. 4:19-cv-00332 (W.D. Mo. Nov 27, 2024) approved the deal over a wave of objections, crediting "the significant practice change relief reflected in the Settlements which require the Settling Defendants, among other things, to eliminate and not enforce industry-wide rules mandating compensation offers to cooperating broker on all MLS listings." The five-year sunset was no obstacle — "A time limitation on practice changes is both common and reasonable," because "No company wishes to stay under the enforcement power of a court indefinitely, nor does a court wish to retain indefinite jurisdiction" — and the release runs to the edge of federal preclusion: for class judgments arising from settlement, "courts have developed a parallel test that gives preclusive effect to all claims – even those not pleaded – that “arise out of the same factual predicate as the pleaded claims.”" As the court put it, "The same factual predicate standard recognizes that a party may be precluded from suing twice for the same wrong."

The settlement did not buy peace on the buyer side of the transaction. Davis v. Hanna Holdings, Inc., 787 F. Supp. 3d 42 (E.D. Pa. 2025) let homebuyers’ Sherman Act claims past dismissal on a vertical theory: "Although Plaintiffs have not plausibly alleged a horizontal agreement between Hanna and its competitor brokerages, they have plausibly alleged a vertical agreement between Hanna and NAR" — NAR membership, executives on NAR boards, and a mandate that brokers follow NAR rules "directly and circumstantially describes an agreement" between entities at different levels of the market. The horizontal theory failed on settled trade-association law: "joining a trade organization, helping develop its rules, and enforcing those rules (even in collaboration with other members of the organization) do not plausibly establish the existence of a prior and separate horizontal agreement among competitors," and that kind of "conscious parallelism" "is not outlawed by the Sherman Act, because it is just as likely to result from independent business judgment as from prior agreement among competitors." The court also refused to force the claims through Amex’s two-sided-platform framework — "brokers sell services to homebuyers and homesellers, not transactions themselves," and "Hanna can earn a commission by only representing one party in a home sale, even if that sale is necessarily a two-party transaction."

Most commission fights, though, still run on doctrine that long predates the settlement. Business Consulting Services, Inc. v. Wicks, 703 N.W.2d 427 (Iowa 2005) states the baseline: "Under common law, a broker is entitled to a commission, even if the sale occurs after the termination of the brokerage agreement, if the broker is the “efficient procuring cause” of the sale" — a cause "originating with a series of events which without break in their continuity result in procuring a purchaser ready, willing and able to buy on the owner’s terms." But the doctrine "only applies if the contract between the parties is silent on the issue of a sale after the expiration of the original listing period. In other words, it is the default rule." Under a written extension clause "the broker is not required, in order to be entitled to a commission, to show that he was the “procuring cause” of such sale," yet he "must establish some causal connection between the broker’s efforts and the eventual sale" — the clause "surely was not intended to benefit a real estate man who has done nothing, by conferring upon him a “windfall” commission." The buyer-representation agreements the settlement made universal get the same contract-first treatment. Sheryl Schey and Tim Schey v. Eric Copper and KWI-1, Ltd., No. 03-24-00321-CV (Tex. App. May 30, 2025) shows how those agreements now get litigated: the form commission was earned when "Client enters into a contract to buy or lease property in the market area" or "Client breaches this agreement," but the court reversed the broker’s summary judgment and rendered a take-nothing judgment, because the damages clause — "Client will be liable for the amount of compensation that Broker would have received under this agreement if Client was not in default" — requires causation, and where the buyers lawfully terminated the only purchase contract during their option period, "based on the undisputed evidence, that amount was zero."

Sort every new matter into one of three buckets before drafting. If the client’s grievance traces to the pre-settlement conspiracy and the client is a class member, run the release analysis first — anything sharing the settlement’s factual predicate is gone, no matter how the new complaint is captioned. If the theory is antitrust, plead vertical agreements with NAR and the MLSs, and treat horizontal allegations built on shared membership as presumptively inadequate, because conscious parallelism will not survive a motion to dismiss. And in the everyday commission dispute, start with the paper rather than the introduction story: extension clauses and buyer-representation agreements displace procuring-cause doctrine, so the case turns on the clause’s trigger and on what the broker would actually have earned but for the breach. Procuring cause remains the default only where the contract is silent — and now that written buyer agreements are mandatory, silence is increasingly rare.
