A contractual warranty is a legally binding promise made by one party to another in a written agreement, guaranteeing the quality, performance, or condition of a product or service. It serves as a form of protection for the consumer, ensuring that the product or service will meet the specified standards and any defects or issues will be addressed by the seller. Unlike a general warranty, which is implied by law, a contractual warranty is explicitly stated in the contract and can be negotiated and tailored to the needs of both parties. It provides peace of mind and adds an extra layer of assurance to the transaction, making it an essential aspect of any business agreement.
