Warranty Law Law and Legal Definition

Warranties may be either express or implied. Express warranties are created by affirmative acts of the seller that are an affirmation of fact or promise made by the seller which relates to the goods and becomes part of the basis of the bargain. Express warranties can be created when the seller describes the goods or furnishes samples. Express warranties create strict liability for the seller, so that negligence need not be proven. In general, express warranties are based on factual statements rather than opinions about the future. An exception is made when it is a professional opinion which can create a warranty. Under the Uniform Commercial Code (UCC), which has been adopted in some form by almost all states, liability for breach of warranty is based on seller status. Manufacturer, distributor, and retailer could all be jointly and severally liable, so that the full amount of damages could be collected from one or any of them. The distributor and retailer may be able to escape liability if the manufacturer is not bankrupt. Purchasers, consumers, users, and even bystanders are entitled to sue in most states for breach of warranty.

Under the Uniform Commercial Code (UCC), which has been adopted in some form by almost all states, there are implied warranties in every sales transaction that the goods sold are fit for the ordinary purposes for which such goods are used. This is called the "implied warranty of merchantability". Under the implied warranty of merchantability, the good sold:

  • Are fit for the ordinary purposes for which such goods are used,
  • Would pass without objection in the trade
  • Is adequately packaged, labeled, and contained
  • Conforms to the promises made in the label

There may also be an "implied warranty of fitness for a particular use". This warranty is created when:

  • At the time of sale, the seller has reason to know the uses the buyer has for the goods, and
  • The buyer relies on the sellers judgment in selecting the goods
  • This implied warranty is not created if the buyer's knowledge of the goods is as great as the seller, or the buyer has a professional consultant,
  • The buyer supplies specifications to the seller

Implied warranties are part of every UCC contract unless disclaimed by the seller. Implied warranties are often disclaimed, which is legal as long as the disclaimers are conspicuous, such as in bold face print. Warranty disclaimers have been held a material alteration, such that they would not be part of the contract if the term was added in the acceptance. Although a seller cannot disclaim an express warranty, he can disclaim implied warranties.

A contract may contain the phrase "represent and warrant", which means to indicate and guarantee or assert something. For example, a disclaimer of warranties may provide as follows:

"We do not endorse, represent or warrant the accuracy or reliability of any of the information, content, advertisements or other materials contained on, distributed through, or linked, downloaded or accessed from our service. We do not endorse, represent or warrant the quality of any products, information or other materials displayed, purchased, or obtained as a result of or in connection with the service, and we do not endorse, represent or warrant the service, security or practices of any of the vendors whose products or services are included on the service. Any reliance upon any information, content, advertisements, materials, products, services or vendors included on or found through the service shall be at the user's sole risk. "

Additional Definitions


A product or service warranty (also known as guarantee) is a promise, from a manufacturer or seller, to stand behind the product or service. It is a statement about the integrity of the product and about the seller's commitment to correct problems should the product or service fail. Product and service warranties have become standard practice in most U.S. industries, although opinions vary somewhat regarding their impact on sales. But misleading language in these guarantees has the capacity to spark significant legal troubles for small businesses that run afoul, however inadvertently, of legal guidelines. Consumers can ask the courts to enforce warranties, whether they are express, implied, written, verbal, or given in any other way. Federal, state, and local government entities establish the regulatory basis upon which warranties are judged. The Federal Trade Commission (FTC) is the ultimate arbiter of warranty law in the United States. The FTC's primary tool in monitoring product and service guarantees is the Magnuson-Moss Consumer Warranty Act.


The law recognizes two basic kinds of warranties—implied warranties and express warranties.

Implied Warranties

Implied warranties are unspoken, unwritten promises, created by state law, that go from the seller or merchant to the customers. Implied warranties are based upon the common law principle of "fair value for money spent." The Uniform Commercial Code (UCC) provides for two basic types of implied warranties that occur in consumer product transactions. They are the implied warranty of merchantability and the implied warranty of fitness for a particular purpose. The "implied warranty of merchantability" is a seller's basic promise that the goods sold will do what they are supposed to do and that there is nothing significantly wrong with them. In other words, it is an implied promise that the goods are fit to be sold. According to the law, merchants make this promise automatically every time they sell a product they are in business to sell. By contrast, the implied warranty of "fitness for a particular purpose" is a promise that a seller makes when the customer relies on the advice that a product can be used for some specific purpose. For example, suppose a woman comes to an office supply store and asks for a printer that is able to print 1,000 sheets of paper per hour. If the office supply company recommends a particular model, and the customer buys that model on the strength of this recommendation, the law says that the office supply company has made a warranty of fitness for a particular purpose. If the printer recommended proves unable to produce 1,000 pages per hour, even though it may effectively print 800 pages an hour, the implied warranty of fitness for a particular purpose is breached.

Express Warranty

Unlike implied warranties, express warranties are not automatically a part of the sales contract based on state law; rather, they are explicitly offered warranties. They are promises and statements, made voluntarily by the seller or manufacturer, about a product or service and about the commitment to remedy defects and/or malfunctions that the customer may experience. Express warranties can take a variety of forms, ranging from advertising claims to formal certificates. An express warranty can be made either orally or in writing. While oral warranties are important, only written warranties on consumer products are covered by the Magnuson-Moss Warranty Act.


The Federal Trade Commission requires that written warranties bestowed in connection with the sale of a product or service explicitly detail the following information:

  • Who is covered by the warranty
  • Length of warranty
  • Description of the products, parts, properties, or characteristics covered by or excluded from the warranty
  • Steps for customer in the event that warranty coverage comes into play
  • Warrantor's response when confronted with product/service malfunctions, defects, or failures
  • Any exclusions of or limitations on relief such as incidental or consequential damages
  • Statement that indicates that some states do not allow such exclusions or limitations
  • Statement of consumer legal rights
  • Any limitations on the length of implied warranties, if possible


The Magnuson-Moss Act does not require businesses to provide warranties to customers. Indeed, some business owners decide that written warranties are not even necessary to enjoy success in their chosen field of endeavor. But other manufacturers and retailers are convinced that warranties help sell their products, pointing to the popularity of service contracts and the like.

Businesses that choose to provide written warranties may choose from two types: full and limited. FTC regulations concerning full warranties are considerably more stringent than those that apply to limited warranties. According to the Magnuson-Moss Act, "fully guaranteed" products or services must meet the following five criteria:

  • Customer receives full money back or replacement or repair of any defective part of product in the event of a complaint
  • Prompt and free repairs
  • If repairs are not fully satisfactory to the buyer, a prompt refund is available
  • Customer has no responsibility beyond reporting the defect to the company
  • Acknowledgment of all implied warranties

Limited warranties, which must be prominently labeled as such, limit the liability of the manufacturer or service provider. A limited warranty may offer to replace defective parts free, but only do so for a limited length of time, or require that the consumer ship the product to a manufacturer-approved service center. The distinctions between full and limited warranties and the obligations of manufacturers to honor them vary from state to state, so it is up to the consumer to carefully read the literature and understand what is covered before the purchase.


Vulnerability to express and/or implied warranties can be reduced somewhat through the use of disclaimers. A disclaimer is a means of denying that you are making one or more express or implied warranties. In the absence of a disclaimer, a breach of warranty will often give the purchaser of the faulty item the right to recover the cost of the item as well as additional damages caused by that breach of warranty.

Small business consultants note that warranties—both express and implied—can be negotiated with buyers, but they urge business owners to use specific language when adding such disclaimers to a sales contract. The term "exclusive remedy," for instance, can give a seller of products or services significant legal protection when it is used to explicitly limit a buyer's legal options in the event of complaints about product defects or workmanship. If, however, the customer is left without a working product, the seller may be sued no matter what agreement was signed, on the grounds that it's a remedy that "fails of its essential purpose." Obviously, the obligations imposed by law in the areas of warranty are extensive, so small business owners should make sure that they consult a legal expert so that they can develop the most effective disclaimer possible.


Extended warranties are somewhat controversial, but often profitable, warranty packages offered by manufacturers and service providers. Manufacturers sell these warranties, which are basically extensions of basic warranty packages, in hopes that the extended warranty will not be needed or used, thereby resulting in profits. Consumers buy them for peace of mind, reasoning that they are protecting their initial outlay of money. The controversy revolves around what the warranties cover. Some extended warranties are actually service agreements, resulting in higher charges than might be expected under a warranty. In other cases the fine print in the warranties exclude the very things that the consumer assumes would be covered.
