Federline's attorney, Mark V. Kaplan, said his client's spousal support payments of $20,000 a month from Spears will end Nov. 15. He requested an additional $50,000 for legal expenses, E! News reported.
In court documents filed in Los Angeles Superior Court, Kaplan said Spears should help pay Federline's legal fees, stating her average monthly income was $737,868.
While not revealing his client's monthly salary, Kaplan claimed Federline has "no net income" after paying for unspecified expenses.
In another development, Spears' attorney, Laura Wasser, said she doesn't have enough time to prepare for approaching discovery deadlines and court hearings because of a scheduled Aug. 17-Sept. 3 vacation and would be unavailable for any depositions scheduled during that time, Entertainment Tonight reported.
Spears filed for divorce from Federline in November 2006 after a little over two years of marriage. The divorce was finalized in July.
