n contract law, a warranty has various meanings but generally means a guarantee or promise[1] which provides assurance by one party to the other party that specific facts or conditions are true or will happen. This factual guarantee may be enforced regardless of materiality[2] which allows for a legal remedy if that promise is not true or followed.
Although a warranty is in its simplest form an element of a contract, some warranties run with a product so that a manufacturer makes the warranty to a consumer with which the manufacturer has no direct contractual relationship.
A warranty may be express or implied, depending on whether the warranty is explicitly provided (typically written) and the jurisdiction. Warranties may also state that a particular fact is true at one point in time or that the fact will be continue into the future (a "promissory" or continuing warranty).
