Ghislaine Maxwell has said Jeffrey Epstein's suicide in prison last year is to blame for the "uniquely onerous conditions" she is facing in jail.
The British socialite is currently awaiting trial on charges she procured teenage girls for the disgraced financier Epstein to abuse. She denies the claims.
Epstein was found unresponsive in his cell in the Metropolitan Correctional Centre in New York on August 10 last year. He was pronounced dead a short time after he was found in his cell.
Maxwell is claiming through her lawyers that his suicide means she is being treated differently than other prisoners who are also awaiting trial.
The 58-year-old has asked a judge to help improve her treatment in a Brooklyn federal lock-up, saying difficult conditions in jail limit her computer access and frustrate her ability to provide for a trial scheduled for next July.
Her lawyers said she should be housed in the general population at the Metropolitan Detention Centre rather than under restrictions that limit her time outside her cell to three hours a day.
“As a result of what occurred with Mr Epstein, Ms Maxwell is being treated worse than other similarly situated pretrial detainees, which significantly impacts her ability to prepare a defence and be ready for trial,” the lawyers wrote.
They said she is watched around-the-clock by security cameras and multiple prison guards, including individuals who do not seem to be usual staff workers.
“These prison guards constantly observe Ms Maxwell and take notes on her every activity, including her phone conversations with defence counsel,” they said.
“Until recently, Ms Maxwell was subjected to suicide watch protocols, including being woken up every few hours during the night and being forced to wear special clothing.”
They said this was occurring even though she “has never been suicidal and was never diagnosed as exhibiting risk factors for suicide”.
Her cell is searched multiple times each day and she has been forced to undergo numerous body scans, the lawyers said.
A spokesman for the prosecutors declined to comment.
Maxwell is held without bail after US District Judge Alison J Nathan concluded days after her July arrest at a New Hampshire estate that she was a risk to flee.
The lawyers also asked Judge Nathan to order prosecutors to reveal the identities of three women whose claims of sexual abuse by Epstein and Maxwell in the 1990s formed the basis of charges against her.
They said they need the identities to properly investigate their allegations of abuse at residences in New York, Florida, New Mexico and the United Kingdom.
The women were not identified in an indictment in Manhattan federal court that charged Maxwell with recruiting and grooming them for abuse when they were under the age of 18.
The indictment, to which Maxwell has pleaded not guilty, alleges that one victim was 14 when she was recruited.
Maxwell’s lawyers noted that Epstein is alleged to have abused dozens, if not hundreds, of girls and women so it would be hard to guess which women were working with prosecutors.
The judge ordered prosecutors to respond to the letter from defence attorneys Mark Cohen Christian Everdell by Thursday.
