CRMLS Seeks Declaratory Judgment, Files Complaint Against Compass, Inc.
CRMLS said Compass wants to profit from cooperative listings while avoiding submission rules, and it is organizing a legal defense fund to back the policy.
On Monday, October 5, 2026, California Regional Multiple Listing Service rejected demands from Compass to cease enforcement of cooperation policies and filed for a declaratory judgment in the Southern District of New York.
Compass threatened a lawsuit in a September demand letter, alleging CRMLS's cooperation rules violate antitrust laws, while CRMLS argues Compass seeks to benefit from shared listings while withholding its own.
CRMLS CEO Art Carter announced the organization of an MLS Cooperation Legal Defense Fund to support legal efforts. "I want to be clear: this case is about more than defending CRMLS from a lawsuit," Carter said.
Seeking judicial affirmation, CRMLS aims to prove its marketplace principles—transparency, equal listing access, and cooperation—are lawful and appropriate, though Compass has rejected this reasoning and advanced competing legal arguments.
The dispute reflects industry-wide friction over the "persistent and increasing presence of off-MLS home marketing," with Compass threatening similar litigation against other multiple listing services refusing to meet its demands.
