It seems that back in May the two decided to divide their assets and also talked about child custody.
Moreover, in the document obtained by TMZ, the two established that Brooke will get primary physical custody and Charlie will get visitation.
Mueller will receive $55,000 per month in child support “under no circumstances shall the child support paid by Charlie for Bob and Max be less than the child support paid by Charlie to Denise Richards for Sam and Lola.”
She will also receive money from several income sources and $1 mil so that Charlie could have the family house.
According to documents, the separation date seemed to have been 12/25/09, the same day Sheen was arrested for domestic incident involving Brooke.
