REX filed an anti-trust lawsuit against NAR and Zillow in March of 2021. In January of 2022, NAR filed a countersuit alleging that REX makes false and misleading claims to deceive consumers, "discouraging them from obtaining the pro-consumer, pro-competitive benefits provided by NAR members and independent, local multiple listing services marketplaces." NAR sought an injunction preventing REX from continuing its false and misleading practices, the monetary damages determined at the trial and the reimbursement of costs and attorneys' fees Three weeks later, in late February, REX filed a motion to dismiss, challenging the legality of the claims made by NAR in the countersuit. NAR spokesperson Mantill Williams stated that NAR was disappointed in the court's decision.
