Can't Find the note holder of the seller's 2nd mortage

[Dustin S.]

Hi all I am under contract to purchase a property where the seller hasn't paid on her 2nd mortgage in years. The original note holder went under in 2003 all of their assets were acquired by 2 small banks one sold to chase and one stills exists neither Chase nor the small bank say the hold the note. The seller's credit doesn't show the debt. Title is willing to insure the deed and my lender is even ok with everything. The closing attorney wants everyone involved to sign a hold harmless, Indemnity agreement. Seller is worried about future financial consequences I don't know enough about this sort of thing to calm the seller down. Can anyone help enlighten me Please.
