The 41-year-old musician and Monique have a five-year-old daughter Reign together, reported TMZ online.
Monique has asked for child support for Reign and also for her 10-year-old son from a previous relationship.
Monique said in court documents that the rapper has 'publicly and privately proclaimed this child as his own'.
Monique also has asked for alimony, life insurance, private school, vacations, summer camp and other expenses.
The former publicist also wants Timbaland, whose given name is Timothy Zachery Mosley, to pay for her legal fees. She also is seeking 'rehabilitative alimony' and permanent alimony in addition to funds while divorce proceedings continue.
Timbaland has been a fixture on the music scene since the mid-1990s and has worked with many of the music industry's biggest stars, including Justin Timberlake, Nelly Furtado, Jay-Z, Bjork, 50-Cent, Ginuwine and the late Aaliyah.
