Promissory notes can be unsecured, secured, payment in installments, or on demand, as well as made with or without interest.
The person making the promissory note may be called the debtor or maker of the note. The person loaning the money may be called the lender or creditor. If you default on a promissory note by failing to make a payment on time, the holder of the promissory note may give notice of default and if the past due payment is not paid, file an action to collect the entire balance of the note plus any interest due. If the note is secured, the holder may seek to obtain the security as full or partial satisfaction of the debt
