A filing in U.S. District Court in Buffalo says San Diego attorney Jeffrey Lake is now representing Paul Ceglia (SEGG'-lee-uh), of Wellsville, N.Y.
Lake replaces the New York firm of DLA Piper and the Buffalo firm of Lippes Mathias Wexler Friedman. Dennis Vacco, a partner in the Buffalo firm, declined to comment Wednesday on the switch.
Lawyers for Ceglia and Palo Alto, Calif.-based Facebook are due in court Thursday for a hearing on the case.
Ceglia claims a contract he and Zuckerberg signed in 2003 entitles him to half ownership of Facebook. Zuckerberg calls the document a fraud.
