The declaration in a court filing today is meant to counter Jolie Pitt's assertion in documents a day earlier that Pitt has paid "no meaningful child support".
In the papers which were lodged with LA Superior Court, Brad's lawyers said he: "adamantly disputes the contention that he has not paid child support".
Brad Pitt and Angelina Jolie split two years ago and things are still very messy.
The "Maleficent" star filed for divorce in September 2016, but divorce proceedings were ultimately put on hold while they sorted out their child custody issues.
The incident was reported and Pitt was investigated by both the Federal Bureau of Investigation and Los Angeles County Department of Children and Family Services, but was later cleared of wrongdoing. "Jen can't imagine what it must be like to fight with someone as powerful as Angelina over your own kids", a source claimed.
As previously reported, Jolie filed court documents asking a judge to both finalise their divorce and force Pitt to pay child support for their six children, as well as retroactively pay for what he has allegedly missed as per an informal agreement.
"Brad was asked to assist in the expense of a new home for Angelina and the children, but instead he loaned Angelina money, for which he is charging her interest on a payment plan", she continued. Pitt's legal team went on to slam Jolie and her attorney's recent claim, calling it "a thinly-veiled effort to manipulate media coverage". "Angelina will of course honour that loan".
This is especially common when the divorce is drawn out, as in the case of Pitt and Jolie.
ET has reached out to Pitt's rep for comment. "Angelina has had to shoulder the majority of those without his contribution for the past two years".
They tied the knot in a secret ceremony in August 2014, and share six children together: Maddox, 17, Pax, 14, Zahara, 13, Shiloh, 12, and twins Vivienne and Knox, 10. "Brad was coping with Angie's hard moves when everything was sealed, but now that she is changing attorneys and going public with her filings again, he feels like she has taken off the gloves and is fighting dirty", the source continued.
