Priscilla Presley has filed papers in Los Angeles Superior Court challenging a critical portion of her late daughters estate.

Elvis Presley s widow is arguing that a 2016 amendment to her daughters Promenade Trust was approved using an invalid signature of Lisa Marie Presley , who died of a heart attack on Jan. 12 at age 54.

Lisa Marie was granted sole access to her dads fortune when she turned 25 in 1993.

Priscilla Presley claims in the 13-page document filed Thursday that she and her daughters former business manager Barry Siegel had been named as co-trustees in the event of her daughters death. But a late addition replaced their names with those of Lisa Maries two children with her ex-husband Danny Keough Riley and Benjamin Keogh.

Under the estates current terms, the 33-year-old Zola actor is now the sole trustee since her brothers death by suicide in 2020.

But Priscilla Presley is challenging the authenticity and validity of Lisa Maries signature approving the trustee change, which appears inconsistent with her usual and customary signature, notes the court filing.

In addition, the filing claims the following about the amendment document: It was never delivered to Priscilla during Lisa Maries lifetime (as required by express terms of the trust agreement), it misspells Priscillas name, and it wasnt witnessed or notarized making the change an invalid modification.

The action seeks a court order determining that the purported 2016 amendment is invalid, confirming the validity and existence of the restated 2010 trust, and confirming that petitioner is a current trustee of the trust.

Riley Keough has not yet responded to the court action.

Lisa Marie is also survived by her 14-year-old twin daughters, Harper and Finley Lockwood, with ex-husband Michael Lockwood.

A spokesperson has confirmed that Lisa Maries three surviving children would inherit Graceland.
