Brooke Mueller's lawyers have asked Charlie Sheen's former bosses, Warner Bros. Television, to garnish $55,000 a month from any payments due to the former Two and a Half Men star.
The amount represents Charlie's monthly child support obligation for his twin sons with Brooke, Max and Bob, under the former couple's divorce settlement of May 2.
The request is legally binding as it is based on a ruling last Friday by Los Angeles Superior Court Judge Hank Goldberg.
Sources close to Mueller tell TMZ that Sheen has not defaulted on his payments, but Brooke wants to ensure regular flow of child support in case he runs low on cash.
Earlier this year, Sheen's attorney Marty Singer had reportedly sent a letter to Warner Bros and CBS demanding that Sheen be paid for the remaining eight episodes of Men that were never filmed in the wake of the actor's erratic behavior.
