In October 2011, Jamie McCourt agreed to a divorce settlement in which she would get $131 million and give up any claim to the Dodgers.
Six months later, the Dodgers sold for $2 billion.
"I was surprised I could have made such a huge mistake," she testified Friday.
McCourt returned to Los Angeles Superior Court on Friday, for the first day of a hearing in which she has asked Judge Scott Gordon to throw out the divorce settlement. Frank McCourt, her ex-husband and the former Dodgers owner, also was in court, although Jamie McCourt was the only witness to testify Friday morning.
Jamie McCourt argues that the settlement should be invalidated because Frank McCourt knowingly misled her about the value of the Dodgers during negotiations. Her most significant evidence, at least so far, appears to be an interview in which Peter Cohen, the lead investment banker handling the Dodgers' sale, is asked whether the sale price was more than he had anticipated from the outset.
"No," he said.
Cohen's firm, Blackstone Advisory Partners, was retained by Frank McCourt three months before the McCourts agreed on the divorce settlement.
"When Peter Cohen ... stated for many people that he knew from day one the value was going to be this high," Jamie McCourt testified, "I knew -- or I believed -- that Frank knew all along what the assets were worth and didn't tell me."
