"Angela and Warren are taking some time apart to figure out what is best for [daughter] Isabel and for their relationship," Kinsey's rep, Tess Finkle, told People. "They continue to be friends and spend time together with their daughter."
Lieberstein, a writer, is also the brother of Angela's "Office" co-star Paul Lieberstein – who plays Toby on the hit NBC show.
The couple, who wed in June 2000, welcomed daughter Isabel Ruby in May 2008.
Kinsey, 37, plays uptight Dunder-Mifflin accountant Angela on "The Office."
