warranty

This term carries a strong sense of legal obligation and commercial security. It differs from a guarantee in that a warranty is often a specific, written contract that may be optional or purchased separately, whereas a guarantee is frequently seen as a general promise of quality. In a commercial setting, it shifts the risk of failure from the buyer back to the manufacturer. In legal and real estate contexts, the word functions as a formal assurance of title or condition. It creates a binding promise that certain facts are true, providing the buyer with a legal remedy if those facts are later proven false.
