Ross split from the filmmaker after he was caught kissing his Snow White and the Huntsman leading lady Kristen Stewart in a Los Angeles car park. The illicit romance also torpedoed Stewart's romance with Robert Pattinson.
According to the settlement agreement, obtained by Tmz.com, Ross gets the family home and two other London residences, $25,000 (Gbp14,700)-a-month in spousal support for the next four years and $14,000 (Gbp8,300)-a-month in child support for the couple's two children.
The model, who is now reportedly dating music mogul Jimmy Iovine, also gets 15 per cent of her ex-husband's future movie profits.
She will share joint custody of the kids with Sanders.
