Bills, Notes, and Promissory Instruments

Learn how promissory notes, accommodation bills, and order paper create and transfer payment obligations.

Bills and notes are written payment instruments, but they do not create the same obligation. A promissory note contains the maker’s promise to pay. A bill of exchange contains the drawer’s order directing a drawee to pay. The distinction determines which party must act, whose acceptance matters, and how the payment claim may be enforced.

Evidence to Check

  • Original instrument or authoritative electronic record
  • Identity, authority, and capacity of every signer
  • Principal or face amount, currency, interest, and fees
  • Issue date, acceptance date, maturity, installments, and demand rights
  • Payee or bearer wording, endorsements, delivery, possession, and assignments
  • Collateral, guarantees, reimbursement agreements, and recourse terms
  • Presentment, dishonor, notices, amendments, waivers, and payment history
  • Governing law and jurisdiction-specific enforcement requirements

Common Mistakes

  • Treating every debt document as a promissory note.
  • Calling a bill a guarantee when the signer’s actual capacity is acceptor or endorser.
  • Assuming “order” wording makes an instrument freely tradeable or liquid.
  • Reading a payment instrument without the related loan, sale, security, or collection documents.
