(CNN) Angelina Jolie is claiming in court documents obtained by CNN that Brad Pitt is not pulling his weight when it comes to child support for their six children.

"[Pitt] has a statutory duty to pay child support. As of present, [Pitt] has paid no meaningful child support since separation," Jolie's attorney, Samantha Bley DeJean, writes in the legal documents that were filed on Tuesday.

DeJean goes on to state that Jolie would like the court to have Pitt pay her the money she is owed.

"Given that 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 [request for a court order] for the establishment of a retroactive child support order," the documents state.

A source close to Pitt told CNN, "It is sad that someone would deliberately misrepresent the situation, especially after Brad has continued to fulfill his commitments."
