Email exchanges between Ferguson and Epstein indicate she asked for his financial advice over how to deal with her £6m debt pile while he was still in jail for soliciting prostitution from a minor.
Being named among the Epstein files is not an indication of wrongdoing.
A spokesperson for the former Duchess of York has been approached for comment.
The companies that are set to close are S Phoenix Events, Fergie’s Farm, La Luna Investments, Solamoon Ltd, Philanthrapreneur Ltd and Planet Partners Productions Ltd, none of which have any public profile.
Listings for five of the six companies state there is an “application to strike the company off the register”. That means the company will stop trading and will cease to exist.
The sixth, S Pheonix Events, which also notes the receipt of an application to strike off, lists Sarah Ferguson as the person authenticating the application on behalf of the company.
Ferguson is listed as an active director for three other businesses registered with Companies House: Ginger and Moss, set up as a lifestyle brand to sell tea, jewellery and housewares, a “motion picture production activities” business called Coat, and Librasol, classified under “artistic creation” on the official register for private companies.
