According to Entertainment Weekly, Greg Nevius, a producer on the Chasing Farrah reality show, charged that certain family members are withholding the actress's money.
He cites that a lawsuit filed against him in January which accuses him of embezzlement is an example of the misuse of the Charlie's Angels star's funds.
"I've read Mr Nevius's response to our complaint, which I think contains spurious and outrageous allegations. I'm confident the truth will all come out during the course of the litigation," said estate attorney Howard Weitzman.
The lawyer also represents Fawcett's former boyfriend Ryan O'Neal and her friend Alana Stewart.
