Sue Ann Arnall, the ex-wife of Oklahoma oil magnate Harold Hamm, has deposited a handwritten $975 million divorce check, Hamm's lawyer said on Thursday, in a move that may end an epic divorce battle over a fortune worth billions.

Last month, when oil magnate Harold Hamm was ordered to pay his ex-wife $1 billion in their divorce, he called the ruling "fair and equitable,” publicly thanked the judge and said he was happy to have the case behind him.

The ex-wife of Oklahoma oil magnate Harold Hamm has appealed a November divorce ruling that awarded her $1 billion, citing 78 alleged errors and missteps that caused a judge to grossly undervalue her stake in one of America's greatest oil fortunes.
