A law firm that helped to defend Ghislaine Maxwell, who was convicted of helping Jeffery Epstein sexually abuse underage girls, is suing her for $878,00 (£743,000) over unpaid work.
Her brother and husbands are also subject to the lawsuit.
Denver-based Haddon, Morgan and Foreman alleged in the lawsuit filed on Monday that Maxwell put her brother Kevin Maxwell in charge of paying her legal fees after she was arrested in 2020 - but that he only paid a fraction of what they had charged leading up to and during her trial.
Mr Maxwell urged the firm to keep working on appeal issues after she was convicted despite the unpaid bills and had blamed Maxwell's husband, Scott Borgerson, for getting in the way of making payments, according to the lawsuit.
The lawsuit alleges that Borgerson formed an LLC to buy real estate to shield his wife's assets from creditors.
Two lawyers at the firm - Laura Menninger and Jeffrey Pagliuca - were part of Maxwell’s legal team during her trial in New York.
Maxwell was found guilty in December of sex trafficking, transporting a minor to participate in illegal sex acts and two conspiracy charges.
She was sentenced in June to 20 years in prison and is serving time at FCI Tallahassee, a low-security federal prison in Florida’s capital.
Emails and telephone messages left for two of Maxwell's defence attorneys, Christian Everdell and Bobbi Sternheim, were not returned.
Calls to telephone numbers listed for Mr Borgeson were not returned. Kevin Maxwell could not be immediately located for comment.
In an email, his brother, Ian Maxwell, said nobody in the family, including Ghislaine Maxwell, would comment on the litigation.

According to the lawsuit, Haddon, Morgan and Foreman - a firm founded by former public defenders that has represented other high-profile clients like basketball star Kobe Bryant - first began representing Maxwell in a 2015 lawsuit brought by Virginia Guiffre.
In lawsuits, Giuffre claimed that starting when she was 17, Jeffrey Epstein and Maxwell set up sexual encounters with royalty, politicians, businessmen and other rich and powerful men, including Britain’s Prince Andrew.
Andrew strenuously denied the allegations and agreed to settle the lawsuit against him earlier this year.
