Sure seems like a worthwhile gambit; you could blow $2500 in a failed suit to assemble the originating docs and if the lender can’t come up with them, you could gain well into 5 figures.
It is almost impossible to find a lawyer who will take a case on Student Loan negation. This is because the S.Ct affirmed rulings in many Fed. Circuit Courts that upheld laws passed by Congress to deter all lawsuits for relief of loan obligations.
This was because many of the student debtors were negating loans via the route of bankruptcy. This loophole was closed by an new bankruptcy act that took effect in Oct. 2007 I think.
At any rate, finding a lawyer who will represent a student in an action to renege on the loans is virtually impossible, so a student would have to file the suit Pro Se in most cases.
