Several celebrity gossip outlets reported that the divorcing couple were persuaded to agree to the detente by the Los Angeles County Department of Children and Family Services.
Both will both get one-on-one counseling while Brad has to undergo drug and alcohol testing, TMZ said, despite already voluntarily submitting to a test which came back negative.
Angelina will have physical custody of the six children - three of whom are adopted - while Brad gets a first visit under the supervision of a therapist who will decide how to proceed in the coming weeks.
"This is a completely voluntary agreement, and it is not an order or a mandate of any kind, nor is it any determination of custody," entertainment website People quoted an unnamed source as saying.
It said the plan was effective up until October 20 and that the children would remain with Angelina at a rented LA house.
Angelina, 41, filed for divorce on September 19 citing irreconcilable differences and seeking permanent custody of their children.
The A-listers - given the celebrity monicker "Brangelina" - wed in France in August two years ago, but had been a couple since 2004.
The FBI has said it is gathering information before deciding whether to launch a federal probe into an alleged incident on a plane carrying Pitt and his children back from vacation in France.
It has not offered any details of the allegations but several US media outlets reported that Pitt had been involved in an angry outburst with at least one of his children.
Celebrity news organization Entertainment Tonight said on Thursday that Angelina's team had brought in well-known crisis manager Judy Smith - who was the inspiration for Kerry Washington's character on Scandal.
Brad, meanwhile, hired a New York-based strategic communications firm, along with Beverly Hills divorce attorney Lance Spiegel, whose past clients include Eva Longoria, ET reported.
ET quoted a source close to the couple as saying the two sides had recently been having "productive discussions."
"The fact that things have quieted down is a good sign for everyone," the source told the channel.
Representatives for the couple as well as the Children and Family services department did not respond immediately to a request for comment.
