In it simplest terms, a promissory note is a written promise to repay a loan or debt under specific terms - usually at a stated time, through a specified series of payments, or upon demand. A promissory note will clearly identify the parties, the amount of the obligation, and if necessary, the consideration for the obligation, that is, what the debtor has already received or will receive in return for signing the note. The note will also include the terms of repayment, whether that be in one lump sum or at stated intervals, and, if applicable, the interest rate which will apply. It may also include an "acceleration clause" which will make the entire amount of the note due if a payment is missed.

What follows is a specific guide to drafting key provisions found in most promissory notes.

Paragraph 1: Identifies the Parties, Sum, and the Repayment Terms

The first paragraph of a typical promissory note should begin by listing the parties involved (promissor and promissee), the sum demanded, and the date when or intervals at which the sum must be repaid. The first paragraph may also include the consideration for the debt. This can be a general provision such as "for value received", or could spell out the services or goods that were the subject of the note, if applicable (i.e. legal services, medical services, etc.).

For example, the first paragraph of a typical promissory note might read:

"For value received, John Doe, on behalf of himself, individually, promises to pay to Jane Smith & Associates, Inc., without offset, the principal sum of $3,500.00, on or before the 15th day of June, 2008, for technology consulting services rendered to the undersigned, that remain unpaid to April 31, 2008."

A demand promissory note is a variation of a promissory note which calls for the payment of the sum "on demand" by the promissee, as opposed to calling for payment on a certain date or at certain intervals. The first paragraph of a demand promissory note might be drafted to read:
