Because California is a community property state, Vanessa is likely entitled to half of Kobe's earnings during their 10-year marriage. The LA Lakers star is expected to make $25,244,493 this year, according to ESPN.
Vanessa is being represented by Laura Wasser, who recently repped Kim Kardashian in her divorce from Kris Humphries.
According to the court documents (via TMZ), Vanessa is requesting spousal support and joint custody of the couple's two daughters, 8-year-old Natalia and 5-year-old Giana.
The pair tied the knot in April 2001, and their marriage withstood the star's 2003 sexual assault charges. Though the case was ultimately dismissed, Bryant did admit to having sexual relations with his 20-year-old accuser.
Sources tell TMZ that Vanessa's filing was prompted by infidelity.
