BEIJING, Nov. 2 (Xinhuanet) -- Britney Spears' defiance of a court order is what led to the pop star having to temporarily surrender custody of her two sons to Kevin Federline, according to court documents released Thursday.

    The documents reveal Superior Court Commissioner Scott M. Gorden ordered Spears and Federline not to drive their children unless they are properly insured and have a valid driver's license.

    "At all times, the minor children shall be transported in a properly insured and registered vehicle, which shall be driven only by a properly insured driver who has a current and valid driver's license," Gordon wrote.

    Spears was caught disobeying the order when she was photographed driving Sean Preston, 2, and Jayden James, 1, a few days after the Sept. 28 order.

    She was ordered Oct. 2 to relinquish her children "until further order of the court" when she wasn't able to prove compliance with Gordon's order, namely proof of a valid California driver's license.

    The two previously had joint custody of their sons, and Federline was seeking a greater share of custody. After he got temporary custody, Spears went to a motor vehicles department office and got a temporary driver's license.
