Kenneth Griffin’s Wife Seeks Child Custody Amid Divorce

The wife of Kenneth Griffin, the billionaire founder of Chicago hedge-fund firm Citadel LLC, countered his divorce filing with a demand for sole custody of their children and asked a court to void a premarital agreement she claims to have signed under duress.

Anne Dias Griffin, 43, saying her husband is angling to leave her with less than 1 percent of his wealth after an 11-year marriage, said she signed the prenuptial agreement on the advice of a psychologist three hours before their wedding rehearsal dinner, according to her filing yesterday in state court in Chicago.
