The Los Angeles Times said the voluntary deal will last until Oct. 20.
Both parties also reportedly agreed to undergo individual counseling and Pitt offered to submit to drug and alcohol testing.
Us Weekly said Jolie will temporarily maintain full physical custody of the couple's children. A therapist will supervise at least the first visitation between Pitt and the kids.
Jolie filed for divorce from her third husband on Sept. 19, ending their 12-year romance. The pair are parents to Maddox, 15; Pax, 12; Zahara, 11; Shiloh, 10; and 8-year-old twins Knox and Vivienne.
