The singer-songwriter, the only child of Priscilla and the late Elvis Presley, died on 12 January at the age of 54 after suffering a heart attack. Later, Priscilla disputed a 2016 amendment to Lisa Marie's will. The 77-year-old alleged she and former business manager Barry Siegel had been removed as co-trustees, and had been replaced by Riley and Benjamin Keough without her knowledge. Lisa Marie's son Benjamin died at the age of 27 in 2020. But on Tuesday, lawyers acting for Priscilla and Riley reached a settlement at a Los Angeles court.
