Prenups are supposed to be the ultimate divorce insurance for the wealthy. Yet like insurance, prenuptial agreements are often challenged when there's a claim.
The increasingly bitter and public divorce battle between hedge fund billionaire Ken Griffin and his wife of 10 years, Anne Dias-Griffin, centers on the couple's prenup, signed in 2002. In an Illinois court filing Tuesday, Anne Griffin said the prenup grants her only 1 percent of her husband's wealth. Ken Griffin, the founder of Citadel, is worth an estimated $5 billion.
Anne Griffin's legal claim to break the prenup centers on two arguments. First, she said that she signed the prenup under "duress and coercion" and under the "undue influence" of a psychologist who had a previous professional relationship with Ken Griffin. In the filing, she said she was given the prenup shortly before their wedding date and that she didn't sign it until three hours before the rehearsal dinner.
