"Brooke and Charlie are very passionate about each other, they love each other and want to try and save their marriage," Galanter said Wednesday. "They had a bad night and want to get beyond it. They want to try and resolve their issues."
Galanter – who practices law in Florida and has represented O.J. Simpson – says he filed papers in Aspen, Colo., on Wednesday to alter the protective order put in place after Sheen's domestic violence arrest. He says Sheen, 44, and Mueller, 32, who are parents to twin boys, are seeking privacy to deal with their problems.
"They have absolutely gorgeous little babies and will do all they can to work out their problems," Galanter tells PEOPLE. "I filed papers so the couple can see each other immediately and work through the issues. I hope to meet with Charlie's lawyer in court in the next day or so, but probably not before Monday."
Sheen's Colorado-based attorney had no comment.
Galanter also says he plans to protect Mueller from any type of potential charge of dishonesty. Reports state that she took back some of the allegations against her Two and a Half Men star hubby after she called 911 on Christmas morning claiming that he'd pulled a knife on her. Sheen denied to police that her used a knife to threaten his wife.
"Brooke did not recant her story, she was simply unaware of the consequences when she called 911 and felt bad about it," says Galanter.
