Lisa Marie Presley insists she in massive debt, despite her father's estate bringing in millions in 2016.
Her claim's detailed in court documents, part of messy proceedings between Presley and the singer's former husband of 10 years, Michael Lockwood.
The documents include an accusation Lockwood has hundreds of inappropriate photographs of children on his computer, a claim Lockwood's lawyer says is "highly sensational" and "inaccurate".
Presley says she was "shocked and horrified and sick to [her] stomach" when she discovered the photos. The claims will be addressed in a trial in March, according to Presley.
Despite claims of massive debt, Presley has a 15 percent stake in Elvis Presley Enterprises, which earned US$27 million (NZ$37.5m) in 2016, according Forbes magazine.
Lockwood is asking the court to order Presley to pay him US$40,000 (NZ$56,000) per month in spousal support, saying he gave up his career to work with his wife.
He's also asking for attorney fees of US$100,000 (NZ$139,000) - which is exactly how much Presley gets paid out monthly in an inheritance cheque. That's topped up with NZ$6000 a month and health insurance cover from her father's estate.
But Presley claims she owes millions of dollars in taxes and on credit cards, after her money was mishandled by a business manager. The documents say her home in England is worth less than the debt owed on it.
Presley's 11-bedroom, nine-bathroom East Sussex home was listed on the market for £4.5m in 2016, and is still listed for sale with Sotheby's International Realty. She purchased the home with Lockwood in 2010.
Lockwood claims Presley has more money than she is revealing, while Presley insists he spent $US1 million on her credit cards - a claim Lockwood denies.
The couple's eight-year-old twin daughters are under state protection, and Presley has been living rent-free with her adult daughter, as well as being treated in a facility for undisclosed reasons last year.
