A tentative settlement has been reached in a major legal malpractice lawsuit against Katten Muchin Rosenman, halting a trial that was scheduled to begin with jury selection this week.

Attorneys for the Am Law 100 firm and plaintiff CashCall Inc., filed a stipulation and proposed order Friday that calls for Orange County Superior Court Judge William Claster in California to vacate the Aug. 16 trial and stay the case for 21 days.
