Estimated agreement amount: $1.2 billion
The 2009 divorce between billionaire Bernie Ecclestone, now 88, and wife Slavica, a Croatia-born old model, was at the time thought to be the most expensive in history — in the range of $4 billion. However, the final settlement between Ecclestone and Slavica, now 60, is conjectured by various reports to be in the range of $1 billion to $1.2 billion. The settlement has not been made public, but experts from across the planet believe the latter number is more realistic.
