The Presley family feud has been publicly reported on since the devastating death of Lisa Marie in January.
The 54-year-old was the only child of rock legend, Elvis Presley and his ex-wife Priscilla. She died after suffering from an apparent cardiac arrest at her home.
Shortly after her death, her mother filed a petition in Los Angeles questioning the "authenticity and validity" of a 2016 amendment to her daughter's will, and ultimately asked a judge to set aside the change.
