You know the deal, they're in court bickering back and forth with Keith claiming Lisa has a history of spending money on herself excessively rather than providing for the children, plus he provided evidence that Lisa stole from him in the presence of their kids. Lisa countered that Keith has been violent towards her, but no admitted there was no evidence he has ever been violent with any of his children. The children in question are Jordan Sweat, age 14 and Justin Sweat, age 11. If Lisa does get custody, she is requesting child support. Keith has had custody of the boys since he and Lisa divorced in 2003. Lisa has since been remarried to ex-pro football player Ed Hartwell with whom she has one son who is often seen on the RHoA reality show. Keith refused to allow his two sons with Lisa to be filmed.
