Jamie McCourt had claimed that the 2011 agreement should be dismantled because her ex-husband fraudulently portrayed the value of the Dodgers at below $300 million. He sold the team last year for $2.15 billion.

Los Angeles County, Calif., Superior Court Judge Scott Gordon disagreed, finding that Jamie McCourt, a practicing family law attorney for 20 years who was chief executive officer of the baseball team before the couple split, had sufficient documentation and knowledge of the value of the Dodgers assets when she signed the deal.
