The real estate industry is in the midst of a profound transformation, and the legal battles targeting the National Association of Realtors (NAR) are the earthquakes that are causing the tectonic shifts. Just as the industry began to digest the implications of the landmark Sitzer/Burnett verdict and the subsequent $418 million settlement, a new and aggressive antitrust suit has been filed, this time by Washington, D.C.-area broker William Whittman. This lawsuit is not a simple rehash of the past but an attack on a different, yet equally fundamental, aspect of the NAR’s structure: the “three-way agreement” that mandates local, state, and national membership for access to essential business tools.
This new legal challenge, which seeks a staggering $2 billion in punitive damages and $50 million in treble damages, represents a significant escalation. It shifts the focus from the cooperative compensation model for commissions to the very foundation of the NAR’s membership structure. Whittman’s lawsuit alleges that the association has created a “cartel of unprecedented scale,” an “infestation” that acts as a gatekeeper, stifling competition and bleeding real estate professionals dry through a multi-layered paywall.
The Heart of the Complaint: A “Three-Way” Cartel
William Whittman, a broker at Proplocate Realty, filed his pro-se lawsuit in the U.S. District Court for the District of Maryland. His complaint is not about the amount of commission paid by a home seller, as was the case in Sitzer/Burnett. Instead, it argues that the NAR, in concert with its state and local chapters—specifically Virginia Realtors (VR), Maryland Realtors (MR), the Northern Virginia Association of Realtors (NVAR), and the Greater Capital Area Association of Realtors (GCAAR)—has unlawfully tied access to essential services to mandatory, duplicative, and geographically restricted memberships.
Whittman’s central claim is that the “three-way agreement,” which requires a real estate agent to join the local, state, and national associations to become a “Realtor®,” creates a monopolistic structure. This compulsory membership, he argues, is the only way for a broker and their agents to gain access to critical tools like:
- Multiple Listing Services (MLS): The primary database of properties for sale.
- Lockboxes: The physical devices that allow agents to access properties.
- Standardized Forms: The legal documents required for real estate transactions.
The lawsuit alleges that these associations have “seized control” of these tools, erecting “private tollgates where the law requires none.” For a broker like Whittman, who operates in the greater D.C. area, this means paying separate and expensive dues to different local boards just to access listings and forms in a neighboring county, even within the same state. He claims this system prevented his firm from expanding nationwide, leading to lost agents and millions of dollars in damages. The complaint is filled with passionate language, calling the associations “predatory gatekeepers” and “cancerous growths feeding on REALTORS®.”
The Broader Context: Sitzer/Burnett’s Aftermath
While the Whittman case is distinct in its specific claims, it is undeniably a product of the post-Sitzer/Burnett environment. The Missouri jury’s verdict in October 2023, which found the NAR and major brokerages guilty of colluding to inflate commissions, opened the floodgates for similar litigation and heightened public scrutiny.
The Sitzer/Burnett case successfully challenged the cooperative compensation rule, a long-standing NAR policy that required a listing broker to make an offer of compensation to the buyer’s broker in order to submit a listing to an MLS. Critics argued that this rule effectively tied the buyer’s agent’s commission to the seller’s agent’s fee, preventing true price competition. The NAR’s subsequent $418 million settlement and the new rules it mandates—including a ban on offers of buyer agent compensation on the MLS—were a direct response to this pressure.
The Whittman lawsuit builds on this momentum by tackling a different pillar of the NAR’s business model. While the Sitzer/Burnett case focused on how commissions were set, Whittman’s suit targets the very requirement of membership itself as an antitrust violation. It argues that if access to essential business tools is tied to paying dues to a private organization, that organization is abusing its market power. This shift in legal strategy signals that the antitrust scrutiny of the real estate industry is far from over.
The Ripple Effect: Industry on High Alert
The filing of the Whittman lawsuit sends a clear message that the legal challenges to the NAR’s practices are becoming more diverse and aggressive. The industry is already grappling with the changes brought about by the settlement, including the widespread adoption of buyer-broker agreements and the decoupling of buyer and seller agent commissions.
NAR has consistently defended its membership structure, stating that it is optional and provides valuable benefits such as a unified voice on policy issues, a uniform Code of Ethics, and professional development opportunities. In response to Whittman’s suit, an NAR spokesperson reiterated this stance, highlighting the value delivered to members and noting that two separate courts had previously ruled against similar challenges. However, those rulings have since been appealed, indicating that the legal debate is far from settled.
The Whittman case, if successful, could force a major restructuring of how real estate agents and brokers operate. Instead of a mandatory, tri-layered membership, a single membership might provide statewide or even nationwide access to MLSs and other tools. This could dramatically reduce the costs of doing business for brokers who operate across multiple jurisdictions, fostering greater competition and potentially leading to more flexible and innovative business models.
Furthermore, the lawsuit’s focus on the geographic restrictions of MLS access resonates with many agents who feel burdened by what they see as unnecessary and duplicative fees. The complaint alleges that these rules create a “disjointed system of artificial borders” that hinders an agent’s ability to serve clients seamlessly across metropolitan areas. The legal action, therefore, could serve as a catalyst for a more unified and efficient national real estate market.

A New Era of Competition
The antitrust suit filed by William Whittman is more than just another legal skirmish; it’s a direct assault on the institutional framework that has governed the real estate industry for decades. By challenging the “three-way agreement” and the mandatory membership structure, Whittman is targeting a core source of the NAR’s power and influence.
The Sitzer/Burnett verdict was a reckoning over commissions, but the Whittman lawsuit is a challenge to the very essence of the “Realtor®” brand and the system that supports it. While the legal process will be long and complex, this case serves as a powerful reminder that the real estate industry is entering a new era. It’s an era defined by a move toward greater transparency, increased competition, and a re-evaluation of long-held practices. For brokers, agents, and consumers alike, the outcome of this lawsuit could shape the future of home buying and selling in America for years to come.
