Katherine Jackson will appear in a Los Angeles courtroom today in the hopes of becoming a co-executor of Michael Jackson's multimillion-dollar estate, an attempt to wrest control of her son's fortune from the two men he handpicked to oversee his legacy.

Rather than contest the will outright -- a risky maneuver that if unsuccessful would cost Katherine, 79, the money she already is assured -- the family is instead trying to raise questions about the legitimacy of the executors Jackson named in his will.

Aside from Jackson's children, Katherine Jackson was the only member of the family named in Jackson's will.
