Priscilla Presley is challenging her daughter Lisa Marie's will

"In a legal filing in Los Angeles Superior Court last week, Priscilla Presley disputed the validity of a 2016 amendment to Lisa Marie Presley's living trust that removed her and a former business manager as trustees and replaced them with Lisa Marie Presley's two oldest children, Riley Keough and Benjamin Keough, if Lisa Marie died or became incapacitated. Benjamin Keough died in 2020."
