How it differs from an IOU
An IOU is a simple acknowledgment that money is owed. A promissory note is a more formal, structured document that includes specific repayment terms.
Because of its structure, a promissory note is generally easier to enforce in a dispute than a casual IOU.
Common elements
Promissory notes typically include:
- Principal amount
- Interest rate (if any) and how it accrues
- Repayment schedule — lump sum, installments, or on demand
- Late fees and default provisions
- Security or collateral, if secured
- Governing law and signatures
Secured vs unsecured notes
A secured promissory note is backed by collateral the lender can claim if the borrower defaults. An unsecured note relies only on the borrower's promise to pay.
