Harold Hamm was ordered by an Oklahoma County judge to hand over close to $1 billion to his ex-wife Sue Ann Hamm
Hamm has been told to pay a third of the funds, or $322.7 million, by the end of the year
The couple, who married in 1988, have two adult daughters. They never signed a prenuptial agreement
Hamm, who grew up in rural poverty in Oklahoma, is worth an estimated $14billion
Getting married without prenups might not be such a bad idea afterall.
