Priscilla Presley could win her legal battle against granddaughter Riley Keough as Elvis' ex-wife seeks to invalidate an amendment made to Lisa Marie Presley's will.
The pair have gone head-to-head over Lisa Marie's trust, after a 2016 amendment removed Priscilla and Lisa Marie's former business manager Barry Siegel as trust managers.
A legal expert has claimed Priscilla could triumph in the case if a court determines "improper procedure" was followed.
