A Nashville, Tennessee, judge issued the order on Tuesday, dissolving the union of the Oscar-winning actor and the Grammy-winning country singer.
Judge Stephanie J. Williams confirmed that the couple's agreements regarding asset division and child custody were sufficient, citing "irreconcilable differences" as the reason for the divorce.
Kidman initiated divorce proceedings in September, with all financial and custody matters settled and signed on the day of her initial filing.
Under the agreed plan, Kidman will serve as the primary residential parent for their two teenage daughters, with neither parent requiring child or spousal support.
