The Department of Children and Family Services is investigating Britney Spears and ex-husband Kevin Federline for “multiple child abuse and neglect” complaints in their custody battle, according to court documents released Tuesday. In a request to unseal parts of the case file, an attorney for the agency wrote that there are concerns about the safety and welfare of the two toddlers, Sean Preston, 2, and Jayden James, 1, if they are left in the mother’s care. Though the county agency mentioned investigating allegations relating to Federline, the documents don’t provide details. The agency requested the court not alter the current custody and visitation arrangements until their investigation is completed. Federline has temporary custody of the boys after Spears defied court orders about regular drug testing.

The latest tidbits on the custody battle are in 300 pages of documents released by Los Angeles Superior Court Commissioner Scott M. Gordon. The document dump included previous court rulings, expense reports and income statements for both parents, the names of the custody evaluators selected by Spears’ and Federline’s attorneys and their detailed resumes. Spears had asked the court to seal the custody and visitation schedules in a declaration filed in October, arguing that, “Such information greatly increases the chances that the actions of the media could threaten the safety of the children by, for example, causing a traffic accident.” Spears, whose every errand is trailed by a mob of celebrity photographers, is notorious for distracted driving. She is under investigation for injuring a sheriff’s deputy while exiting the downtown courthouse in her white Mercedes. In 2006, she was photographed driving with her son on her lap. In October, she pleaded not guilty to a misdemeanor charge of driving without a valid driver’s license and later obtained a temporary California license. A misdemeanor hit-and-run charge from an August parking lot crash was dismissed after she paid an undisclosed amount to the car’s owner. Also released in the documents was a bill from Federline attorney Mark Vincent Kaplan. Kaplan is charging $550 per hour for his services. His firm billed Federline for $84,000 in for work in August, plus almost $85,000 for a week of work, mostly depositions, in September. Previously, Gordon ordered the pop star to pony up $120,000 in legal fees that her ex-husband owed his attorney. Spears pays Federline $15,000 per month in child support, and previous court rulings have said that he currently has no income.160Want local news?Sign up for the Localist and stay informed Something went wrong.
