The battle lines are being drawn in divorce of Citadel Investment Group founder Kenneth Griffin and his wife, Aragon Global Management founder Anne Dias Griffin.
A day after Dias Griffin accused her estranged husband of “unilaterally” filing for divorce as she left for a London vacation with their children, Griffin’s lawyers made clear that they consider the couple’s prenuptial agreement “valid, binding and enforceable.”
Griffin, who is worth about $5.5 billion, and his wife signed the prenuptial agreement a day before their 2003 wedding, his lawyers said. The deal “governs all issues resulting from the parties’ marriage, including, but not limited to, maintenance and the division of marital and non-marital property. Prior to the premarital agreement being executed, both parties were represented by counsel, entered into the premarital agreement freely and voluntarily, and each party made a full disclosure of their assets and liabilities.”
Griffin’s lawyers also said that he would seek joint custody of their three young children, whose ages range from two to six years.
The Griffins have been separated for about a year. Griffin recently purchased the apartment below the Chicago penthouse he formerly shared with his wife.
Dias Griffin learned about the divorce filing while in the car on the way to the airport, the Chicago Sun-Times reports. A source told the newspaper that she suspects Griffin chose that time “knowing she couldn’t call him back immediately because their children would overhear the conversation.”
Dias Griffin was surprised by the filing and “thought they were still in settlement negotiations,” the source said. But a source close to Griffin told the Sun-Times that “proposals which had been on the table for the last five months in order to avoid going to court had not come to fruition,” and that a filing “had been bubbling for days.”
Dias Griffin, the source said, “knew [Griffin] was done.”
