From the New York Times’ Gretchen Morgenson:

Guess What Got Lost in the Loan Pool?

WE are all learning, to our deep distress, how the perpetual pursuit of profits drove so many of the bad decisions that financial institutions made during the mortgage mania.

But while investors tally the losses that were generated by loose lending so far, the impact of another lax practice is only beginning to be seen. That is the big banks’ minimalist approach to meeting legal requirements — bookkeeping matters, really — when pooling thousands of loans into securitization trusts.

Stated simply, the notes that underlie mortgages placed in securitization trusts must be assigned to those trusts soon after the firms create them. And any transfers of these notes must also be recorded.

But this seems not to have been a priority with many big banks. The result is that bankruptcy judges are finding that institutions claiming to hold the notes that back specific mortgages often cannot prove it.

On Feb. 11, a circuit court judge in Miami-Dade County in Florida set aside a judgment against Ana L. Fernandez, a borrower whose home had been foreclosed and repurchased on Jan. 21 by Chevy Chase Bank, the institution claiming to hold the note. But the bank had been unable to produce evidence that the original lender had assigned the note, which was in the amount of $225,000, to Chevy Chase.

With the sale set aside, Ms. Fernandez remains in the home. “We believe this loan was never assigned,” said Ray Garcia, the lawyer in Miami who represented the borrower.
