November 2026 | Acme Institute Real Estate Legal Update
The real estate industry is watching an increasingly contentious legal battle between Compass and several multiple listing services.
On November 2, Northern California’s MLSListings became the latest organization to join federal litigation challenging Compass’s approach to marketing properties outside the traditional MLS system.
At the heart of the dispute is a familiar question: Who gets to decide how a seller’s property is marketed?
Compass maintains that property owners should be free to choose their marketing strategies, including public marketing outside the MLS.
The MLS organizations counter that brokerages participating in a cooperative listing service should not benefit from their competitors’ shared listings while withholding their own publicly marketed properties.
The controversy raises important questions about antitrust law, competition, seller instructions, brokerage obligations, and consumer access to housing information.
It also raises an interesting distinction: A seller who genuinely wants privacy is not necessarily in the same position as a seller whose property is publicly advertised but withheld from competing brokers through the MLS.
What should happen when a seller’s marketing instructions conflict with an MLS’s participation rules?
That’s a question worth discussing in every real estate classroom.
The courts have not yet resolved these disputes. We’ll be following the developments as we prepare Acme Institute’s 2027 continuing education programs.
