What is Maker?

Legal Definition
This term is applied to one who makes a promissory note and promises to pay it when due. He who makes a bill of exchange is called the drawer, and frequently in common parlance and in books of Reports we find the word drawer inaccurately applied to the maker of a promissory note. See Promissory note.
