Chicago hedge fund billionaire Ken Griffin and his money manager wife are embroiled in a contentious divorce, and the couple's battles over money had CNBC last month asking, "How can three kids under age 10 cost $1 million a month?" That after court papers indicated Anne Dias Griffin wanted that figure to raise the children. Now, a Friday court filing along with some previously filed papers detail just where some of the money goes each month. Per NBC News and the Chicago Tribune: $300,000 for travel on private jets, $160,000 for vacation rentals (the couple also own five homes), $6,800 on groceries, $7,200 on dining, $8,000 on gifts, and $2,000 on stationery. Griffin also says his wife wanted $450,000 to take the kids on a 10-day winter-break vacation to St. Bart's; he gave her 10% of that amount.
What Dias wants: the prenup voided (she says she was busy planning their wedding when she signed it and wasn't able to properly pore over his financial disclosures; he counters that they hired two wedding planners) and, per state law, the kids' lifestyle funded as it was pre-split. Griffin maintains he's doing the latter and more, as some of what he's funding helps only Dias, in his view: four nannies, a personal chef, a number of house cleaners, and a personal assistant. Griffin is worth an estimated $5 billion and is the richest man in Illinois. Money isn't the only topic the two are tussling over: Dias is seeking sole custody and wants to move the kids to NYC. Griffin states that she had sought to get a provision in the prenup that would allow her to move any children to NYC or San Francisco because "she considered [Chicago] to be unsophisticated." The issue of location ultimately wasn't included in the prenup. The two separated in 2012, and Griffin filed for divorce in July. (Read more billionaire stories.)
