In the lawsuit, filed July 3 in Los Angeles Superior Court, Rowe seeks an immediate payment of $195,000 for attorney fees and $50,000 in living expenses so that she can continue pursuing her child-custody case against him.
The next court hearing on the matter is slated for July 26.
Rowe is the mother of Jackson's two children, Prince Michael Joseph Jackson, 9, and Paris-Michael Katherine Jackson, 8. She gave up her parental rights to the children in 2001 but asked a judge to reinstate them in 2003 after she learned of Jackson's arrest on child molestation charges.
Rowe says in the lawsuit that Jackson stopped making his promised payments to her in October, 2003.
Jackson agreed when they divorced to pay his ex-wife $1 million a year for the first three years after their split and $750,000 annually for six more years. Rowe also received a house in Beverly Hills and a 1998 Ford Explorer. She agreed to visit her children only once every 45 days, according to the lawsuit.
Jackson maintained ownership of his Neverland Ranch and two adjacent properties in Santa Barbara, Calif., other residential and commercial properties, plus a fleet of vehicles that includes two fire trucks, three vintage Rolls Royces, four tractors and nine golf carts.
