In court documents filed earlier this month, the former dancer, 40, claimed he makes less than 1 percent of what Spears does. “We think the reasonable needs for the children while they would be in Kevin’s custody is probably three times what he’s currently receiving,” Federline’s attorney Mark Vincent Kaplan previously told PEOPLE. A rep for Spears has not commented on the court battle.
