KEY POINTS:
Kevin Federline's lawyer wants Britney Spears to pay some of her ex-husband's legal expenses in their divorce case, court documents show.
Attorney Mark Vincent Kaplan said Federline has "no net income" after various expenses, and that his spousal support of US$20,000 ($28,947) a month ends in November.
Spears, meanwhile, brings in an average monthly income of US$737,868. Spears is "clearly the monied party," in the dispute and should pay US$50,000 for Federline's litigation expenses, Kaplan argued.
