Question

Does Promissary Note debt that has been reassigned (legally) end when both originating parties die?

Answer

No, not necessarily, as the note could be part of the decedent's estate who was owed the money. or conceivably could now be held by a still living third party who is a BPV (bonified purchaser for value).of this note.
