Lisa Marie Presley died suddenly in Los Angeles on Jan. 12 of cardiac arrest at the age of 54.
The singer had named her mother Priscilla in 2010 as one of the administrators of her large estate. She had modified her will in 2016 to bequeath her fortune to her eldest daughter, actress Riley Keough.Priscilla Presley had formally challenged this new will in January: her defense argued that she had only discovered the changes after the death of her daughter and questioned the authenticity of her signature.
