Los Angeles Dodgers owner Frank McCourt’s 30-year relationship with his wife Jamie McCourt turned into a nasty courtroom battle. Now, it appears his decade-long relationship with the law firm Bingham McCutchen is headed in the same direction.

Bingham filed a lawsuit against McCourt late Monday in Superior Court in Massachusetts, seeking a declaratory judgment that the firm is not liable for any losses the real estate developer turned baseball team owner might suffer as a result of the pending divorce action.
