The Oscar-winning actress finalized her divorce from celebrity biker Jesse James last week in Texas. The 45-year-old filed for divorce in April after reports surfaced that James had been cheating.
Details of the settlement were sealed by the court, but Bullock's initial filing cited "discord or conflict of personalities" as reason for the split.
The divorce paves the way for Bullock to complete her recent single-parent adoption.
The actress and "Monster Garage" star met in 2003 and married in 2005. It was the first marriage for Bullock, who became a devoted stepmom to James' children: Sunny, 6; Jesse Jr., 12; and Chandler, 15.
Their problems surfaced in March, just 10 days after Bullock won the best-actress Oscar for her role in "The Blind Side." Internet rumors surfaced that James had been unfaithful while Bullock was away making her Oscar-winning film.
James later confirmed he cheated on the actress, saying in a tearful interview on ABC's Nightline in May that he "took a pretty amazing life and marriage and threw it away."
