The first hearing in the action against the Scottish Football Association due to be heard at Edinburgh’s Court of Session, is scheduled for Friday, December 11.
The court action will come just two days after the bid by Mr Ashley, who also owns Newcastle United, to have Mr King thrown in jail accusing him of breaching a gagging order.
The contempt charge has been set for December 9 at London’s High Court and if convicted a sentence of 30 days in prison could be handed down by the judge.
The issue surrounds Mr King for discussing his relationship with Sports Direct during an interview in July.
Mr Ashley's gagging order stopping Rangers from blowing the lid off controversial details of contracts with his retail chain went UK wide in June.
Mr Ashley served legal papers in the case against the SFA last month calling for the judicial review of the SFA ruling made on May 19.
The SFA are expected to defend their position.
