Jolie filed for divorce from the 52-year-old actor on Monday, after two years of marriage.
Jolie, 41, cited irreconcilable differences for their split. She asked for physical custody of the couple’s shared six children – Maddox, Pax, Zahara, Shiloh, Vivienne, and Knox – asking for Pitt to be granted visitation.
She did not request child or spousal support.
The documents state that the couple have been separated since September 15.
“Angelina Jolie Pitt has filed for dissolution of the marriage. This decision was made for the health of the family. She will not be commenting at this time, and asks that the family be given their privacy during this difficult time,” Jolie’s attorney told PEOPLE.
In a statement to PEOPLE Pitt said, “I am very saddened by this, but what matters most now is the well being of our kids. I kindly ask the press to give them the space they deserve during this challenging time.”
A source close to the situation told PEOPLE, “Both Brad and Angelina care very much about their kids and there is sadness on both sides.”
The couple were last spotted together in mid-July, just ahead of their second wedding anniversary – though the insider told PEOPLE Pitt has escaped to France “many time this year because they were fighting.”
“The divorce is a complete shock,” a source close to the couple told PEOPLE. “They have definitely spent more time apart this year, but it’s still a shock. They just celebrated their wedding anniversary together.”
In the wake their split, speculation surfaced about the actor’s relationship with costar Marion Cotillard. The actors are co-starring in the upcoming World War II drama Allied.
The New York Post reported that Jolie had hired “a private eye” to spy on them. “She felt that he was fooling around with [Cotillard] on the set, and it turns out, he was. And that was the final straw,” the paper reported.
However, a source told PEOPLE that the pair’s breakup has nothing to do with Cotillard and denied the comments reported by The Post.
Just last month, sources told PEOPLE that the couple were “as happy as ever.”
“They really are great,” the source said. “They’re really busy, but happy. The kids are getting so big! It’s hard to believe.”

Pitt and Jolie first met on the 2003 set of their 2005 thriller Mr. & Mrs. Smith, and began publicly dating a few years later – after the actor’s split from then-wife Jennifer Aniston.
“Because of the film, we ended up being brought together to do all these crazy things, and I think we found this strange friendship and partnership that kind of just suddenly happened,” Jolie Pitt told Vogue in 2006. “I think a few months in I realized, ‘God, I can’t wait to get to work.’ … Anything we had to do with each other, we just found a lot of joy in it together and a lot of real teamwork. We just became kind of a pair.”
In May 2006, the couple welcomed their first child together, daughter Shiloh, now 10. She joined Jolie Pitt’s adopted brood of Maddox, now 15, and Zahara, now 11.

In 2007, the couple adopted son Pax, now 12, from a Vietnamese orphanage.
The next year, twins Knox and Vivienne were born. Of their new family of eight, Jolie Pitt told PEOPLE at the time, “It is chaos, but we are managing it and having a wonderful time.”
