A trio of Am Law 100 firms are advising on the $1.1 billion sale of Internet Brands—owner of websites like ApartmentRatings.com, CarsDirect.com and Lawyers.com—to private equity giant KKR.

The New York-based buyout shop confirmed Tuesday its purchase of the El Segundo, Calif.-based new media company from private equity rivals Hellman & Friedman and JMI Equity. The deal comes three months after the completion of a joint venture deal between Internet Brands’ Lawyers.com business and LexisNexis’ Martindale-Hubbell unit to deliver marketing services for lawyers.
