I’ve been reading about different financial instruments and came across the term promissory note. From what I understand, it’s a written promise to pay a certain amount of money to someone, but I’m still not clear on the exact details. Can anyone explain what exactly a promissory note is, how it differs from a loan agreement, and in what situations it’s typically used (like business loans or personal lending)? Also, are there any legal requirements or risks involved in issuing one?
