According to NBC News, 43-year-old Jolie made the accusations in a court filing Tuesday in Los Angeles Superior Court and obtained by NBC. "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.
The site also reports that Jolie's lawyer claims that Pitt hasn't paid "meaningful child support" since the two separated nearly two years ago.
Pitt and Angelina, who filed for divorce from Pitt in September 2016, are still fighting over custody of their children. Per the filing, Jolie intends to file for retroactive child support.
Pitt and Jolie have three sons and three daughters, ages 17 and under.
The estranged couple has not yet finalized their divorce, and reportedly put the process on hold as they worked out a shared custody agreement.More news: Trump Touts Iran Sanctions

"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.
Jolie, who underwent a double mastectomy and got her ovaries removed in 2013 to prevent an aggressive form of cancer that killed her mother, grandmother and aunt, also told Vanity Fair that she had developed Bell's palsy.
The arrangement for child support was allegedly informal, per the TMZ report, but Jolie claims that Pitt has not even lived up to those informal expectations.
But the Los Angeles Times quoted a source close to Pitt saying that it was all "a publicity stunt".
Pitt has kept a low profile in the past two years, while Jolie has recently been filming a sequel to fairytale drama "Maleficent" in London and directed a 2017 film about the 1970s Khmer Rouge regime in Cambodia in which more than one million people died.
Pitt's attorney Lance Spiegel did not immediately respond to a request for comment.
