A source told Radar that the actress had a fight with her estranged husband on Friday, August 10, inside his new $19 million Palisades mansion.
"Apparently she didn't like what she saw, because she ordered Ben back into rehab if he wants to see the kids," a source told Radar.
On Monday morning, Affleck, 45, was back at Buddhist rehab facility Refuge Recovery in Los Angeles.
The bust-up came during another twist in the former couple's divorce saga – with Los Angeles Superior Court telling the couple their case could be dismissed as they don't immediately finalize the details of their split.
Garner, 46, confronted Affleck when she returned home following a trip to Sweden with their three kids: Violet, 12, Seraphina, 9, and Samuel, 6.
"After a terse meeting with Ben, Jen agreed to allow him to see the kids — at her house, in her presence," the source continued.
Affleck was seen entering Refuge Recovery early the on August 13 with an iced coffee in hand, just three days after the fight with his ex.
The double Oscar winner – who first checked into rehab in 2001 to get help for his alcoholism – has credited the facility for saving his life.
He secretly completed a stint at the center, which says it offers a Buddhist path to recovering from addiction, in March.
