The pair reportedly spent three hours side by side in a Beverly Hills office with legal professionals.
Brad, 55, who was dressed down in jeans was seen giving a thumbs up as he made his way to his car.
Angelina managed to evade cameras on her way out of the office.
Angelina, 43, filed for divorce from Brad in September 26, citing irreconcilable differences.
It took two years from their split for the pair to reach a temporary child custody agreement.
“It is not permanent but rather a temporary agreement in place, for now, to keep things moving along in the right direction,” a source told WHO of the deal that sees Pitt granted joint physical and legal custody of Pax, 15, Zahara, 14, Shiloh, 12, and 10-year-old twins Vivienne and Knox.
