Charlie Sheen and Brooke Mueller have mutually agreed to modify custody details regarding their 14-year-old twin sons. According to court documents obtained by Us Weekly, Sheen, 58, requested on Thursday, January 19, joint physical and legal custody with Mueller, 46. He was granted the emergency request with stipulations including that he would “immediately” assume “sole legal custody” of sons Bob and Max “in the event Brooke tests positive" for drugs or alcohol. The paperwork noted that the children primarily reside with Sheen while Mueller received “reasonable and flexible periods" of custody and visitation. She will need to test for drugs and alcohol as often as required by her probation officer within 24 hours of a written request from Sheen or his attorney. Sheen will continue to provide Mueller additional financial assistance from time to time but he won't be signing on any new lease or month-to-month extension for any home, the documents state. He will also keep paying Mueller's rent at her current home as long as she is clean and sober.
