An Oklahoma County judge has ordered oil magnate and Continental Resources Chief Executive Officer Harold Hamm to pay nearly $1 billion in a divorce judgment, according to a court filing made public on Monday.

Special Judge Howard Haralson found that Hamm should pay his ex-wife Sue Ann Hamm a total of $995.5 million, with about a third of the funds, or $322.7 million, to be paid by the end of the year, the filing says.

Hamm will then be required to pay the rest of the judgment, some $650 million, in installments worth at least $7 million per month, the filing says. Sue Ann Hamm has already been awarded around $25 million since the case was filed in 2012, the filing says.
