Promissory Note with Installment Payments

An installment promissory note records not just the amount borrowed, but when each payment is due. It is useful for personal loans, seller financing and family arrangements where a single lump-sum due date is unrealistic.

What to prepare

  • Full names and addresses of borrower and lender
  • Principal amount, in words and figures
  • Interest rate and how it is applied
  • Number of installments, amount per installment and due dates
  • Grace period, late-payment charge and prepayment terms

Good to know for this situation

  • Use a table or annex for the installment schedule so there is no dispute about dates.
  • State whether interest is fixed or variable, and whether it is simple or compounded.
  • Keep proof of each payment, such as bank transfers or signed receipts.
  • For large amounts or secured loans, have a lawyer review the note and any collateral document.

Questions

Does an installment note need to be notarized?
Not necessarily to be valid between the parties, but notarization makes it stronger evidence. Some lenders require it.
Can the borrower pay early?
Only if the note allows it, or if the lender agrees. Add a prepayment clause if early payment is intended.
What happens if one installment is missed?
The note should state whether the lender can demand the entire balance or only the missed installment. Without a clause, the remedy may be limited.
