Two of the women, "Katlyn Doe" and "Lisa Doe", met Epstein when they were 17, and the third, "Priscilla Doe", when she was 20, according to the lawsuits.

All said Epstein used a "vast enterprise" of associates to recruit them, subject them to unwanted sex acts and keep them under his control.

All three said the abuse continued after Epstein reached a deal with federal prosecutors in Florida in 2007.

The deal allowed him to plead guilty to state prostitution charges and spend 13 months in a county jail, during which time he was allowed to leave during the day on work release.

The lawsuits said Epstein had Katlyn and Priscilla flown to Florida so he could continue to abuse them even while he was on work release from jail, while he made Katlyn feel dependent by promising to pay for medical treatment she needed.

He exerted control over Lisa and Priscilla by promising, falsely, to advance their dance careers, their suits added.

The lawsuit by Katlyn alleges that in 2013, Epstein forced her to marry one of his associates who needed the arrangement to become a legal resident of the United States.

In addition to Epstein's estate, the lawsuits target several corporate entities he allegedly controlled.

A lawyer for the executors of the estate could not immediately be reached for comment.

Epstein was arrested on July 6 and pleaded not guilty to charges of sex trafficking involving dozens of underage girls as young as 14.

Just two days before his death, he signed a will placing all of his property, worth more than $US577 million ($851 million), in a trust called The 1953 Trust, named for the year of his birth.

The will was filed on Thursday in the Superior Court of the US Virgin Islands, where Epstein was domiciled.

According to the petition to the court, Epstein's personal property included some $US56 million in cash, $US18 million in planes, cars and boats, and nearly $US200 million in hedge funds and private equity investments.
