Citadel Investment Group founder Kenneth Griffin has filed for divorce from his wife of 10 years.
Griffin’s lawyers filed the petition for dissolution yesterday, they said in a statement. His wife, Anne Dias Griffin, said through her attorney that the divorce filing was unilateral and made “with no notice to either me or my client.”
Robert Cohen said Griffin’s filing came after “she had just left for summer vacation with their three young children and would therefore be unable to respond.”
The Griffins are among Chicago’s most prominent philanthropists; he is worth an estimated $5.5 billion. It is unclear whether the couple signed a prenuptial agreement before their 2004 marriage, which was Griffin’s second.
Dias Griffin was a hedge-fund manager in her own right as founder of Aragon Global Management. She turned the firm into a family office in 2009 to give herself more time to focus on her family and other projects, which include a news Web site dedicated to promoting political and fiscal reform in the Midwest.
“Anne’s highest priority remains here family, especially the well-being of her children,” Cohen said. “She is hopeful that this personal matter can be resolved privately and in the best interests of her children.”
Griffin’s lawyers also asked for discretion. “This is a personal matter, and the family asks for privacy as they work through this process and focus on the well-being of their children.”
