U.S. Bank seeks to enforce a promissory note as a holder in due course, relying on an indorsement on a separate piece of paper. The note and the separate piece of paper have matching holes showing they were once stapled together, but are now simply sitting next to each other in the loan file. Is U.S. Bank a holder? See Mitchell v. U.S. Bank, N.A., 2017 WL 3707274 (Mass. Land Ct. 2017). What if the allonge had been executed one day before the note? Does that pre-dating affect its validity when it's subsequently attached to the note? See Bank of New York Mellon v. Florida Kalanit, 770 LLC, 2019 WL 1781954 (Fla. App. 2019)
