"Angelina is not in need of money and could easily put a payment plan together for child support with Brad without this aggressive approach, but this is the way she chooses to handle things", the source continues.
ET has reached out to Pitt's rep.
Pitt and Jolie have three sons and three daughters, ages 17 and under. According to the Jolie source, it's "ultimately up to the court" to set up "an arrangement that is in the children's best interest".
The court filing did not specify what "meaningful" support is, but a spokesman for Pitt says that the 54-year-old actor has fulfilled all of his commitments.
The same source has also claimed Jolie is 'fueled with anger and has gotten ridiculously unreasonable'.
But Jolie's camp have rubbished these claims, telling People that the new filing requests a hearing to move forward with their divorce. "The motion today was created to move all of that forward".
"Jolie's attorney, Samantha Bley DeJean, wrote in the brief, "[Pitt] has a duty to pay child support.
The latest news comes after a spokesperson for the actress slammed reports suggesting she was parting ways with her attorney during a crucial juncture in her custody battle.
DeJean goes on to state that Jolie would like the court to have Pitt pay her the money she is owed.
But the Los Angeles Times quoted a source close to Pitt saying that it was all "a publicity stunt". "It's deplorable that someone for their own selfish reasons leaked selective portions of the confidential and sealed court record to create an inaccurate and unfair picture of what is really happening".
