TMZ Video Used in McCourt Divorce

The L.A. Dodgers divorce just got even uglier, and this time a TMZ video became evidence against the lawyer Jamie wants to represent her.

Frank McCourt's lawyers went to court today, objecting to Jamie McCourt's request to bring D.C. attorney David Boies into the case to represent her. Boies had applied to the court for permission to practice in a California court for this case only.

Frank's lawyers filed legal docs -- obtained by TMZ -- arguing that Boies violated a cardinal rule in the legal profession -- interrogating an L.A. Dodgers employee, despite the fact that all Dodgers employees are represented by counsel.

Boies grilled a security guard at Dodger Stadium on March 27, when Jamie tried in vain to get inside to move her stuff out of her office. Frank's lawyers say the guard is an employee of the Dodgers, who are represented by counsel and Boies had no right to intermeddle.

Nonetheless, the judge allowed Boies to enter the case. BTW, for whoever ends up paying the legal bill, Boies is really expensive.
