Oil man Harold Hamm's ex-wife seeking to cash divorce check: source
Earlier, Arnall's lawyers had said she did not want to accept the check for fear of hurting her appeal of a divorce ruling she viewed as short changing her.
It's not yet clear if Arnall's attempt to cash the check will lead to her withdrawing her appeal in the divorce ruling or how it may affect the Continental Resources chief executive's own appeal of the case to Oklahoma's Supreme Court.
