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."
