In general, a warranty is a promise, assurance, or statement made by the warrantor regarding the existence or accuracy of specific facts or the condition, quality, quantity, or nature of a good or property. There are express and implied warranties, both of which are legally binding commitments.
In contracts, a warranty is a stipulation that makes part of the contract. Therefore, the warrantor must strictly comply with the warranty. Otherwise, there would be a breach of warranty.
Warranty and guarantee do not have the same legal meaning.
