CNN  —  The future of Graceland, Elvis Presley’s historic Memphis home, could be determined in court Wednesday after a bizarre set of events set the late singer’s granddaughter against a mysterious company that claimed Elvis’ daughter gave it Graceland’s deed. A hearing is scheduled for 10 am ET in the Shelby County, Tennessee, Chancery Court to determine whether a foreclosure auction of Graceland can proceed. The sale had been scheduled for Thursday but was stopped – at least temporarily – when Presley’s granddaughter, Danielle Riley Keough, sued to block it. Keough took ownership of the estate and popular tourist attraction after her mother and Elvis’ daughter, Lisa Marie Presley, died in January 2023. Who holds the rights to Graceland? But a company called Naussany Investments & Private Lending LLC claims that Lisa Marie Presley failed to pay back a $3.8 million loan it had given her – and Naussany claims Presley had put up Graceland as collateral against the loan. Seeking repayment, it had scheduled an auction of the estate. This was no typical foreclosure sale. Keough filed a lawsuit earlier this month, claiming there was no such loan. She also claims Naussany isn’t even a real company. “These documents are fraudulent,” Keough’s lawsuit alleges. “Lisa Marie Presley never borrowed money from Naussany Investments and never gave a deed of trust to Naussany Investments.” The lawsuit alleges Naussany Investments & Private Lending LLC “appears to be a false entity created for the purpose of defrauding.” Although Naussany provided what appears to be a 2018 notarized promissory note signed by Lisa Marie Presley to put up Graceland as collateral, Keough’s lawsuit said that was a forgery. In a signed affidavit, the notary public denied ever notarizing anything that Lisa Marie Presley had signed. When CNN attempted to reach Naussany Investments & Private Lending LLC by phone, the number was no longer in service. The business was listed in a court document from Keough’s attorney as being located in Kimberling City, Missouri, but CNN was unable to locate a business in the state of Missouri by that name via the secretary of state’s office. CNN was also unable to locate a business by that name when searching nationwide. Elvis Presley Enterprises, the company that manages Presley’s estate, concurred that Naussany’s claim was illegitimate. “Elvis Presley Enterprises can confirm that these claims are fraudulent,” the company said. “There is no foreclosure sale. Simply put, the counter lawsuit has been filed is to stop the fraud.” A judge last week granted a temporary restraining order, preventing Naussany from selling Graceland. Wednesday’s hearing could determine whether the sale can go forward or not. An estate in dispute Following Lisa Marie Presley’s death, Keogh and her grandmother, Priscilla Presley, fought over the rights to her estate – including Graceland. Ultimately, Keough and Presley settled, and Keough became Graceland’s sole owner. In 2004, Lisa Marie Presley sold 85% of Elvis Presley Enterprises’ assets in a deal reportedly worth more than $100 million. But she maintained complete ownership of the Graceland mansion and Elvis’ personal items housed in what is now the Graceland museum, according to the Graceland website. Graceland is one of the South’s biggest tourist draws, visited by hundreds of thousands of people each year, Graceland says on its website. Lisa Marie Presley annually earned seven figures from it, based on a court filing in her 2022 divorce. Keough is a well-known actor, appearing in “Mad Max Fury Road” and other Hollywood hits. She also appears in Hulu’s “Under the Bridge.” CNN’s Raja Razek, Joe Sutton and Alli Rosenbloom contributed to this report.
