Custody Issues SurfaceIn the following year-plus, the exes kept the peace and got back to their lives. Jolie continued her advocacy work, produced an Oscar-nominatedanimated movieand resumed acting withMaleficent 2. Pitt starred in and produced numerous movies and started dating, according to source, being seen with MIT professorNeri Oxmanin April.

Then in June 2018, their clash over custody wound up surfacing in public court documents. A judge ruled that Jolie couldlose primary custodyof their kids if she didn’t allow them each to form a “healthy and strong relationship” with Pitt. The judge set a detailed visitation schedule of when Pitt could spend time with the children in London, where Jolie has been filming for the summer, and in L.A. The ruled also granted Pittunsupervised cell phone contactwith the kids.

A spokesperson for Jolie called the public release of the documents “deplorable.”

A Child-Support SpatJolie’s attorney Samantha Bley DeJean filed papers on Aug. 7 stating that Pitt “has a duty to pay child support. As of present,[Pitt] has paid no meaningful child support since separation.”

In a filing the next day, Pitt’s lawyer Lance Spiegelslammed Jolie’s filingas “unnecessary” and “a thinly-veiled effort to manipulate media coverage.” The filing state that Pitt“loaned” Jolie$8 million to help her purchase her current home and has contributed over $1.3 million “for the benefit of [Jolie] and the minor children.”

Jolie’s lawyer shot back in a statement calling Pitt’s filing “a blatant attempt to obfuscate the truth and distract from the fact that he has not fully met his legal obligations to support the children.” Bley DeJean said Jolie is paying interest on the $8 million loan: “A loan is not, however, child support and to represent it as such is misleading and inaccurate.”
