The 44-year-old actor had been living in a guest house on the estate he shared with estranged wife Jennifer Garner and their three children - Violet, 11, Seraphina, eight and Samuel, five - but after the former couple officially started divorce proceedings last month, almost two years after they separated, he has now gone his own way and is already settled into the new abode.
A source told People magazine: "The family house is for Jen and the kids now. Ben won't have any things at the house."
"The kids are doing well. They have been to Ben's new house."
It was previously claimed the Argo star had "slowly" been moving from the house, with the intention to be there full time from this week.
