Kevin Federline, Britney Spears

He is also asking that Spears to contribute to attorney’s fees incurred to date and future fees anticipated to be no less than $250,000 as well as $100,000 for forensic accounting fees. The documents also state that Spears refuses to provide her financial records to allow them and the court to determine a proper guideline for the child support and, as such, Federline argues he will need experts to help determine those figures.

“We tried to see if we could voluntarily come to an agreement on what the increased number of child support would be and in the process for doing that, [Britney’s team] came back with several conditions that were not acceptable,” Federline’s attorney Mark Vincent Kaplantold E! News in a statement. “As a result, Kevin had to file a formal request that the court determine what the appropriate amount for child support is. If the court decides that this should be a reasonable needs order, then we’re going to use expert testimony to establish what the reasonable needs are of the minor children.”
