The star of TV's "Two and a Half Men" and his wife, Brooke, are both to appear in an Aspen courtroom before District Court Judge Boyd.
They are expected to ask him to modify a restraining order that separates them. Attorneys say they want to reconcile.
The actor is scheduled to enter a plea in his Dec. 25 arrest on suspicion of felony menacing, second-degree assault and criminal mischief.
A police officer's arrest affidavit quoted Brooke Sheen as saying the actor held a knife to her throat. Sheen denies threatening or hitting his wife.
