A promissory note form is a written promise to pay money to someone. A promissory note form can be used to create a legally binding agreement when lending money or financing the sale of personal property. You can complete a promissory note’s payment schedule to fit your needs. You set out the terms of the loan in an unsecured promissory note form or a secured promissory note form: how much is loaned, the interest rate (if any), the rate of repayment and the security interest (if any). Or have the entire amount come due on a specified date. Our promissory note forms are set up to be fillable — you add the terms for your particular promissory note form by filling in the blanks with your computer.
