A "Breach of Warranty" occurs when a seller fails to fulfill a promise or guarantee about a product's quality or performance. Warranties can be express, meaning they are clearly stated, or implied, meaning they are assumed based on the nature of the transaction. When a warranty is breached, the buyer may seek remedies such as repairs, replacements, or refunds. In legal terms, a breach of warranty can lead to a lawsuit if the buyer suffers damages due to the defective product. This concept is important in consumer protection, ensuring that buyers receive what they were promised when purchasing goods or services.
