Buyers often rely on promises about quality. A warranty is a guarantee—express or implied by law—about the nature, quality, or performance of goods or services, creating liability if the promise is not met.

Express warranties arise from affirmations of fact, descriptions, or samples. Implied warranties, such as merchantability and fitness for a particular purpose, are imposed by commercial statutes in many sales of goods. Disclaimers and limitations are regulated and sometimes ineffective against consumers.

Breach of warranty supports remedies including repair, replacement, refund, or damages. Warranty law sits at the intersection of contract and consumer protection. Clear warranty documents and realistic marketing claims reduce disputes after sale.
