Meanwhile, the actress' lawyer, Samantha Bley DeJean, filed a two page brief in Los Angeles Superior Court (obtained by TMZ), stating: "[Pitt] has a duty to pay child support. As of present, [Pitt] has paid no meaningful child support since separation."
Since the former couple have yet to officially divorce any financial agreement was an "informal arrangement" according to DeJean.
"Given the informal arrangements around the payment of the children's expenses have not been regularly sustained by [Pitt] for over a year and a half, [Jolie] intends to file an RFO [a request for a court order] for the establishment of a retroactive child support order," the filing read.
It is unknown at this time what -- if any -- informal agreement Jolie and Pitt had arrived at prior to this filing.
Reps for both Pitt and Jolie have been contacted by TooFab.
