"I'm sure the world thinks, 'Sonja doesn't have to worry. She's got that husband there for her,'" she says. "But I'm on my own."
According to court documents filed by the Bravo star, Adams Morgan -- a descendant of famed financier J.P. Morgan and former President John Adams -- is refusing to pay Morgan a $3 million lump-sum divorce judgment along with $300,000 in back alimony.
Morgan also alleges that while her ex lives on his private, $19 million island off Stamford, Conn., she has been barred from selling or visiting their properties in Colorado and France.
As a result, Sonja says she may have to sell her $6 million Manhattan town house. (In November, Morgan filed for Chapter 11 bankruptcy protection; she listed $19.8 million in debt and $13.5 million in assets in her bankruptcy petition.)
