This guide sets out warranty law as it actually operates, beginning with how express and implied warranties are created and ending with what a claim is worth. It covers the federal consumer product statute in detail — disclosure, designation, minimum standards for full warranties, the tie-in prohibition, the bar on disclaiming implied warranties, and the informal dispute settlement rules — alongside the state sales law that supplies most of the substance. Separate parts address disclaimers and their formal requirements, remedy limitations and the doctrines that defeat them, notice and limitations deadlines, privity, and revocation of acceptance. Service contracts are treated separately because they are contracts rather than warranties and are regulated differently. The guide closes with claim handling, litigation strategy, damages, fee-shifting, and compliance guidance for sellers and manufacturers.
