McCourt testified that although she is a lawyer, she left legal matters up to lawyers working for her and her husband.
"I said protect the houses for us," she said. "Protect them from business risks."
Frank McCourt alleges that his wife wanted a firewall between her $70 million in real estate and his Dodgers, which were bought with borrowed money.
She said her understanding was that the Dodgers would continue as community property, regardless of what the marital property agreement stated.
"They took their whole estate and poured it into the baseball team," said Dennis Wasser, Jamie McCourt's attorney. "To suggest, because there was some risk there, that she would say, 'You know what? I don't want any risk. Take everything that we've ever worked for. It's yours, Frank.' That is absurd."
Yet, the agreement spells out a specific division, according to Frank McCourt's attorney.
He said that property titled to him, including the Dodgers, would be solely his property.
But Jamie McCourt's side points to a single word that was changed on the agreement after it was signed: that Frank's property first excluded, and then included the Dodgers.
It is the writing of Silverstein, who was representing both the McCourts.
However, Jamie McCourt has said she signed the agreement, but did not read it.
"They should be null and void because they say different thing," Wasser said about the agreement. "One says the Dodgers go to Frank, the other says the Dodgers go to both of them. What happens is that you have inconsistent documents."
The couple, who married in November 1979 and have four grown sons, separated on July 6, 2009.
Frank McCourt, 57, fired his 56-year-old wife as the Dodgers' chief executive officer a day after the team lost a playoff series to the Philadelphia Phillies. She filed for divorce five days after her firing.
