On Monday, Anderson appeared on "Good Morning America," claiming Sheen grabbed her by the throat and used racial slurs.
Sheen is suing Anderson, saying she tried to extort a million dollars from him to remain quiet about the incident.
Sheen's attorney said on Tuesday that the accusations against his client are false.
"The fact that any victim would wait a month and announce her story on 'Good Morning America' belies even imagination. If she was truly a victim, she should have gone to the police, should've filed these charges the night it occurred or even a day or two afterwards. To try and extort money in exchange for the threat of going on the air is just improper and that's why we're suing her and suing her legal team," said Galanter.
Anderson is scheduled to meet with a New York District Attorney, who is considering a second-degree harassment charge against Sheen.
