Brad Pitt will seek joint physical custody of his six children with Angelina Jolie in their ongoing divorce.

The actor filed his response to Jolie’s petition on Friday, and is asking to share joint physical and joint legal custody of the children with his soon-to-be ex-wife, PEOPLE confirms. In her Sept. 19 divorce filing, Jolie requested sole physical custody with visitation rights for Pitt.

Custody of the couple’s six children — Maddox, 15, Pax, 12, Zahara, 11, Shiloh, 10, and 8-year-old twins Knox and Vivienne — has been a major point of contention between the former couple as they’ve been locked in divorce negotiations over the past several weeks.

The children remain continue to live with Jolie and a source close to the situation tells PEOPLE: “The kids are Angie’s sole focus. She’s cancelled everything else – work, everything. She’s been home each day, supporting them, helping them with homework, been there constantly. And no, this isn’t with a big staff of nannies and helpers.”

Meanwhile, a separate source close to the family said recently: “They are still working on issues that they can’t agree on. It seems their issues still involve the kids.”

“Brad and Angie haven’t had any contact, and it’s all being worked out via their teams,” said the family source recently. “It’s just a sad situation.”
