5. Harold Hamm and Sue Ann Hamm

Settlement Amount: $1 Billion

In 2012, Continental Resources CEO Harold Hamm and wife Sue Ann Hamm filed for divorce after 24 years of marriage. The oilman had an estimated $11 billion net worth prior to the filing. There was speculation that he had not signed a prenuptial agreement and his wife would be entitled to half of his wealth.

In November, Hamm, 68, was ordered to pay Mrs. Hamm a total of $995.5 million with $322.7 million expected to be paid before the end of 2014. The ruling is subject to appeal and came after a 10-week trail.

The remaining $650 million will be paid in installments of $7 million each month.
