Katherine Jackson's quest for money may have just cost her dearly ... because TMZ has obtained legal papers from a South Korean newspaper that is going after everything she makes ... until she pays off a $13 million debt.
Segye Times, a South Korean newspaper, filed papers with the Michael Jackson estate, informing the court it got a judgment against Katherine in 1994 for $4 million. That's when the newspaper advanced Katherine, Joe and Jermaine $5.5 million for a series of Jackson family concerts that never took place.
Segye claims with interest the judgment now exceeds $13 million, and it wants an order from the judge forcing the estate to pay Segye any money the estate might pay Katherine.
Now here's how Katherine screwed herself. By making all the deals she's been making -- for books, gala events and such -- she's made it clear to the world her goal is to roll in dough and Segye has taken notice.
