Claiming it would be a good thing for her two sons, an attorney for Britney Spears asked a court commissioner Monday to prevent county authorities from reviewing court filings in her child custody dispute.

The Los Angeles County Department of Children and Family Services is a "large bureaucracy with thousands of employees" where the details of the case could easily leak out, argued Thomas Paine Dunlap, an attorney for Spears.

The department is looking into Spears’parenting skills. Ex-husband Kevin Federline's attorney, Mark Vincent Kaplan, argued that if the court turned files over it should identify and release only relevant issues.

Following Dunlap and Kaplan presentations, an attorney for the department asked for the hearing to be closed, and Superior Court Commissioner Scott M. Gordon's decision was not disclosed.

Among other issues addressed behind closed doors Monday was a new holiday visitation schedule for Sean Preston, 2, and Jayden James, 1. No details were released. The boys spent the night before Thanksgiving with their mother and Thanksgiving Day with their father.
