Attorneys asked a judge to deny a live Internet feed from the courtroom requested by TMZ Productions when Brooke Mueller appears on Jan. 23.
The 34-year-old Mueller faces a felony charge of possession of cocaine with intent to distribute and a misdemeanor assault charge.
She was arrested Dec. 3 after a woman reported being assaulted at a nightclub.
The Aspen Times reported that police found between four and five grams of cocaine when they contacted Mueller.
Sheen and Mueller divorced earlier this year after Sheen was arrested on suspicion of assaulting her in 2009. He completed his probation in November 2010.
