They're on, they're off, and apparently, they're off. Lawyers for Charlie Sheen and Denise Richards filed legal papers Wednesday asking a private judge to handle the couple's divorce, Sheen's publicist said.

"They asked the court to go to a private arbitrator. They want to keep it private," publicist Stan Rosenfield said Wednesday.

He would not comment further. Richards' publicist could not be reached for comment.

The papers, filed in Los Angeles Superior Court, requested that the case be taken out of court and assigned to retired commissioner Jill S. Robbins.

Richards filed for divorce last March after three years of marriage. The relationship appeared to dissolve in the public eye just months before Richards gave birth to their second child.

Months later, the couple seemed to have reconciled. In November, Sheen flashed his wedding ring on CBS' "Late Late Show," telling host Craig Ferguson "things are really good."

The two were married in June 2002. They met while shooting the independent film "Good Advice" in 2000 and appeared in 2003's "Scary Movie 3."
