I find it hard to believe she is broke so that may be a ploy to get out of support...but then again..she is not stable..so it is possible.
The whole thing is tragic for the kids. I think she sold of a huge portion of the rights to Elvis. They may have blown through that money.

Lisa Marie Presley has sold 85% of all trademark rights to Elvis’ name, likeness and image, intellectual property, including EPE’s collection of photographs, archival documents and footage, successful music publishing catalogue and other investments. The title to Graceland and its surrounding property, including most of Elvis’ personal effects, will remain with Lisa Marie Presley. Lisa Marie said: ‘I feel confident that Bob Sillerman and his team are the right people to do this with. ‘My greatest responsibility to my father is to preserve and protect his legacy, and this is an exciting new structure that opens up an incredible array of opportunities with a major infusion of new investment capital to do just that’. Lisa will collect $53 million ($A69 million) in cash and the rest will be split almost in half between preferred stock and debt repayments.
