DocketXWarranty
A warranty is a legally binding promise that a specific fact about a product or service is true, and that the thing will meet that promise.
What it actually is
In a court case, a warranty is a statement of fact or a guarantee made as part of a contract, for example, in a sales agreement for goods or real estate. It can appear as an express written or spoken promise, or an implied one automatically required by law (such as that a product is fit for ordinary use).
Why it matters in your case
If a warranty is breached (the promise is broken), you may have a legal claim for damages or to cancel the deal. It shifts the burden: you do not have to prove the seller was at fault, only that the promised fact was false when made.
The common misunderstanding
People often confuse a warranty with a guarantee of performance over time. Actually, a warranty is a statement about a fact at the time of the sale, not a promise the product will never break, though some extended warranties do promise future repairs.
