From what I understand, a "representation" is a statement of fact that underpins e.g., a contract.
My understanding is that a "warranty" is a promise that if something isn't true, it will be "made true" during the course of the warranty's life. E.g. "If your widget doesn't work within the first year of sale, we'll give you another one that works."
Within the above context, I am confused by the dual term "representation and warranty" or "represents and warrants" in a contract. What exactly does it mean? Put another way, how can something be both a statement of fact and a promise? Or does a term that draws on two other terms have a "third" meaning?
