The 77-year-old actress wrote in documents obtained by 'Entertainment Tonight' "there are many issues surrounding the authenticity and validity of the purported 2016 amendment", such as the misspelling of Priscilla's name and that the amendment "was never delivered to [Priscilla] during Lisa Marie Presley's lifetime as required by the express terms of the Trust."

She also argued Lisa Marie's signature on the 2016 paperwork "appears inconsistent with her usual and customary signature."

Priscilla wants the amendment to be declared invalid by a judge.

At the time of Lisa Marie's death, she and Barry were engaged in a court battle over the management of her fortune.

The Promenade Trust holds a 15 per cent interest in Lisa Marie's father, the late Elvis Presley's Graceland estate and the licensing of his intellectual property.
