An **e-note** (short for **electronic promissory note**) is a digital version of a traditional paper promissory note used in lending, particularly for mortgages. It serves as the borrower’s promise to repay a loan and is created, signed, and stored electronically in compliance with laws such as the U.S. Electronic Signatures in Global and National Commerce (E-SIGN) Act and the Uniform Electronic Transactions Act (UETA). E-notes are managed through secure electronic vaults to ensure authenticity and prevent duplication.
