You’re staring at an MBE question about a defective toaster that caught fire, and you’re stuck deciding whether the buyer can recover under an express warranty or implied warranty of merchantability. The fact pattern mentions the seller saying “this is top quality” and you’re wondering: is that puffery or a warranty? And what’s the difference between merchantability and fitness for a particular purpose anyway?
UCC warranties are tested relentlessly on the MBE, and they’re easy points if you know the framework. The examiners love these questions because they can layer warranty issues with remedies, statute of frauds, and modification rules. Let’s break down exactly what you need to memorize.
The Three Types of Warranties Under Article 2
The UCC creates three distinct warranty categories, each with different formation requirements and different ways to disclaim them. Getting these mixed up costs you points.
Express warranties are created by the seller’s words or conduct. Under UCC Section 2-313, an express warranty forms when the seller makes any affirmation of fact or promise relating to the goods that becomes part of the basis of the bargain. This includes descriptions of the goods, samples, or models. The key phrase is “basis of the bargain”—the buyer doesn’t need to prove they relied on the statement, just that it was part of the deal.
Here’s the trap: not every statement creates an express warranty. Puffery (statements of opinion like “this is the best car in town” or “you’ll love this”) does not create a warranty. But saying “this engine has 50,000 miles” or “this fabric is 100% wool” absolutely does. The distinction turns on whether the statement is objectively verifiable.
Implied warranty of merchantability arises automatically in every sale of goods by a merchant who deals in goods of that kind. You don’t need magic words. If a merchant sells goods, those goods must be fit for their ordinary purpose. Under UCC Section 2-314, merchantable goods must pass without objection in the trade, be of fair average quality, be adequately contained and packaged, and conform to any promises made on the label.
The classic example: a consumer buys a sealed jar of peanut butter from a grocery store. The jar contains glass shards. The grocery store breached the implied warranty of merchantability because peanut butter is not fit for its ordinary purpose (eating) when it contains glass. The buyer doesn’t need to prove the seller said anything about the product’s quality.
Implied warranty of fitness for a particular purpose is narrower and requires three elements: (1) the seller has reason to know the buyer’s particular purpose, (2) the seller has reason to know the buyer is relying on the seller’s skill or judgment to select suitable goods, and (3) the buyer actually relies on the seller’s expertise. This warranty applies whether or not the seller is a merchant.
Think of it this way: A buyer tells a paint store employee she needs paint for a boat hull that will be in saltwater. The employee recommends a specific paint. That paint must be fit for saltwater use, not just for ordinary painting. The buyer’s reliance on the seller’s expertise triggers this warranty.
When Warranties Arise: Merchant vs. Non-Merchant Sellers
One of the most tested distinctions is who can create which warranty.
Express warranties can be created by anyone—merchant or not. If your neighbor sells you his used car and says “the transmission was just rebuilt,” that’s an express warranty even though your neighbor isn’t a car dealer.
The implied warranty of merchantability only arises when the seller is a merchant with respect to goods of that kind. A merchant is someone who deals in goods of that kind or holds themselves out as having special knowledge or skill related to those goods. The grocery store selling peanut butter is a merchant. Your neighbor having a yard sale is not.
The implied warranty of fitness for a particular purpose applies to any seller, merchant or not, as long as the three elements are met. But as a practical matter, it usually involves merchants because buyers typically rely on professional sellers’ expertise.
Disclaiming Warranties: What Works and What Doesn’t
This is where the MBE gets tricky. Each warranty type has specific disclaimer rules.
To disclaim an express warranty, the seller must avoid creating it in the first place. You cannot create an express warranty with specific language and then disclaim it with boilerplate. If the seller says “this watch is waterproof to 100 meters” and the contract includes “all warranties disclaimed,” the express warranty survives. Express warranties and disclaimers are inconsistent, and the express warranty wins.
To disclaim the implied warranty of merchantability, the disclaimer must mention “merchantability” by name. If the disclaimer is in writing, it must be conspicuous (typically bold, caps, or contrasting type). The magic phrase is “AS IS” or “WITH ALL FAULTS”—these disclaim all implied warranties without naming them specifically.
To disclaim the implied warranty of fitness for a particular purpose, the disclaimer must be in writing and conspicuous, but it doesn’t need to use the word “fitness.” A general disclaimer like “THERE ARE NO WARRANTIES WHICH EXTEND BEYOND THE DESCRIPTION ON THE FACE HEREOF” works.
Here’s an MBE favorite: a contract says “Seller disclaims all warranties” in small print at the bottom. Does this disclaim merchantability? No. It doesn’t mention merchantability by name, and it’s not conspicuous. The implied warranty of merchantability survives.
Privity: Who Can Sue for Breach of Warranty?
Traditional contract law required privity—a direct contractual relationship between plaintiff and defendant. But warranty law has expanded beyond this.
For vertical privity (manufacturer → retailer → consumer), most states follow one of three alternatives from UCC Section 2-318. Alternative A extends warranties to natural persons in the buyer’s household or guests. Alternative B extends to any natural person who may reasonably be expected to use or be affected by the goods. Alternative C extends to any person (including businesses) who may be expected to use or be affected by the goods.
On the MBE, assume Alternative B unless told otherwise. This means the buyer’s family member injured by a defective product can sue for breach of warranty even though they didn’t buy the product. But the manufacturer’s ability to disclaim still applies—if the warranty was properly disclaimed to the buyer, the family member can’t recover either.
For horizontal privity (remote purchaser suing manufacturer), most jurisdictions allow it for personal injury but not for pure economic loss. If a defective tire causes a crash and injuries, the driver can sue the tire manufacturer. If the tire just wears out prematurely (economic loss), some jurisdictions require the buyer to sue the retailer, not the manufacturer.
Breach of Warranty vs. Strict Products Liability
This distinction confuses many bar takers because both allow recovery without proving negligence. But they’re different claims with different rules.
Breach of warranty is a contract claim governed by the UCC. It requires notice to the seller within a reasonable time after the buyer discovers or should have discovered the breach. It allows the seller to disclaim liability. It’s subject to the UCC statute of limitations (four years from delivery, not from discovery of the breach).
Strict products liability is a tort claim. It requires proof that the product was defective and unreasonably dangerous. It does not allow disclaimers. It applies a discovery rule for the statute of limitations. It does not require notice to the seller.
When you see an MBE question about a defective product, identify which claim is being tested. If the call of the question asks about the seller’s disclaimer or whether proper notice was given, you’re in warranty land. If it asks whether the product was defectively designed or whether the manufacturer can escape liability through a disclaimer, you’re in tort land.
What You Must Memorize for Test Day
Lock in these bright-line rules:
Express warranty: Created by affirmation of fact, description, sample, or model. Not created by puffery. Cannot be effectively disclaimed if created.
Implied warranty of merchantability: Automatically arises when a merchant sells goods. Goods must be fit for ordinary purpose. Disclaim by mentioning “merchantability” (conspicuously if written) or using “AS IS.”
Implied warranty of fitness for particular purpose: Requires seller’s knowledge of buyer’s purpose and buyer’s reliance on seller’s expertise. Disclaim with conspicuous writing (no magic words needed).
Merchantability vs. fitness: Merchantability = ordinary purpose, merchant seller. Fitness = particular purpose, any seller, requires reliance.
Notice requirement: Buyer must notify seller of breach within reasonable time or be barred from any remedy (UCC Section 2-607). This trips up many examinees who forget this procedural requirement.
When you’re memorizing these rules, the hard part isn’t understanding the concepts—it’s keeping the elements and exceptions straight under time pressure. The implied warranty of merchantability requires a merchant seller, but fitness for a particular purpose doesn’t. Express warranties can’t be disclaimed, but implied warranties can. Merchantability disclaimers must use the word “merchantability,” but fitness disclaimers don’t need specific language.
This is exactly why active recall beats passive re-reading. You need these distinctions instantly accessible when you’re 45 seconds into an MBE question. If you’re looking for all the UCC warranty rules organized for active recall testing, FlashTables covers this in the Contracts table with every element, exception, and distinction laid out in two-column format. The structured repetition helps you spot the issues faster when the clock is running.
The MBE will give you fact patterns where multiple warranty theories apply, or where a valid disclaimer blocks one claim but not another. Your job is to work through the framework methodically: What type of warranty? Was it properly created? Was it properly disclaimed? Did the buyer give notice? Master these building blocks, and UCC warranty questions become some of the most predictable points on the exam.
