“When potential buyers are on Zillow’s website, Zillow tricks them into signing up with a Zillow agent,” the complaint states. Defendants in the lawsuit — filed in U.S. District Court for the Western District of Washington — include Zillow Inc., Zillow Group Inc., Zillow Homes Inc. and Zillow Listing Services Inc. Attorneys with Hagens Berman also argue that Zillow is fully aware of how those costs may impact consumers. Zillow estimates that it possesses roughly 66 percent of the U.S. real estate audience share, Hagens Berman said, with 80 percent of consumers going directly to Zillow. The Moehrl suit — in which Hagens Berman represented homeseller plaintiffs — was one of the most significant of those cases.
