Question

You verbally promise to pay your sister tomorrow the $25 that you owe her. This promise however, is not a negotiable instrument because: it is not in writing. it is not payable at a specific time. it is not a promise to pay a specific amount. it does not contain an unconditional promise.

Answer 1

You still need to pay your sister the $25 because you must keep your word. A promise is a non-negotiable instrument because it is not in writing. If you were to have it in writing that it could be a more arguable case.
