Sonja Norwood filed a lawsuit in L.A. County Superior Court on Monday against the star, after Kardashian allegedly abused the use of a credit card given to her to make "one (and only one)" purchase on behalf of Norwood.
However, Kardashian is accused of giving the American Express card to other members of her family--Khloe, Kourtney and Robert Jr. The three are alleged to have run up debts of $120,635 on the card in 2006 and 2007.
The suit also claims thousands of dollars from the unauthorized payments were charged in the family's Dash and Smooch stores, reports TMZ.com.
The Kardashian family has yet to comment on the case.
