Historical Context & Motivation
Before a single issue of offer, acceptance, or breach can be analyzed on a contracts question, a preliminary threshold inquiry must be resolved: which body of law governs the transaction? American contract law developed along two parallel tracks. The common law of contracts, rooted in centuries of English judicial decision-making, evolved through case-by-case adjudication and was eventually synthesized in the Restatement (Second) of Contracts (1981). Meanwhile, the rapid growth of commercial trade in the twentieth century exposed the inadequacy of common law rules for transactions involving the sale of tangible goods, prompting the creation of a statutory framework specifically designed for merchants and commercial parties.
This dual-track development means that American contract law is not monolithic. A contract for the construction of a building is governed by entirely different default rules than a contract for the purchase of steel beams used in that building. On the bar exam, correctly identifying the governing body of law is the gateway to the entire analysis—an error at this stage can cascade through every subsequent issue, from formation to remedies. The central question, then, is deceptively simple: Is this a transaction in goods?
Core Principles & Definitions
The determination of governing law rests on a set of foundational definitions drawn from UCC § 2-105 and general common law doctrine. Understanding these definitions is essential because the bar exam frequently tests borderline scenarios—such as mixed contracts involving both goods and services—where the classification is outcome-determinative. The following core concepts form the analytical framework that every contracts question demands.

Visual Decision Framework
The diagram above captures the analytical structure that should guide every bar exam contracts question. Note that the flowchart is strictly hierarchical: the subject matter inquiry always comes first. Only when a contract involves both goods and services does the analysis require the additional step of applying the predominant purpose test. A common error on the MBE is failing to perform this threshold analysis altogether, leading examinees to apply UCC rules (such as the battle of the forms under § 2-207) to what is actually a common law services contract.
How the Classification Works — Distinguishing Goods from Non-Goods
Defining "Goods" Under UCC § 2-105
The statutory definition is deceptively straightforward. Under UCC § 2-105(1), goods are defined as "all things (including specially manufactured goods) which are movable at the time of identification to the contract for sale." Several important principles flow from this definition. First, the test is temporal: the item must be movable at the time it is identified to the contract, not at some earlier or later moment. Second, the test focuses on tangibility and movability—intangible rights such as patents, copyrights, and contract rights are excluded. Third, certain items that might seem like goods are expressly excluded: money used as the medium of exchange (though rare coins sold as collector's items qualify as goods), investment securities governed by Article 8, and things in action.
Borderline Categories
| Category | Classification | Rationale |
|---|---|---|
| Growing crops | Goods (UCC) | Crops are movable once harvested and are identified to the contract while still growing. UCC § 2-107(2). |
| Timber, minerals, structures to be severed by seller | Goods (UCC) | When the seller is to sever them from realty, they are treated as goods. UCC § 2-107(1). |
| Timber, minerals severed by buyer | Real property (Common Law) | When the buyer is to sever, the contract is treated as a real property transaction. |
| Software (custom-developed) | Likely services (Common Law) | Most courts treat custom software as predominantly a service contract. But off-the-shelf, mass-produced software on physical media is often treated as goods. |
| Blood transfusions | Service (Common Law) | Most jurisdictions have enacted "blood shield" statutes classifying blood transfusions as services, not sales of goods, to shield hospitals from strict liability. |
| Electricity | Split of authority | Some courts classify electricity as a good (it is metered and sold in units); others treat it as a service. |
The Predominant Purpose Test in Detail
The leading case on the predominant purpose test is Bonebrake v. Cox (8th Cir. 1974), which held that a court should look to the contract as a whole to determine whether its predominant factor, thrust, or purpose is the rendition of a service or the sale of goods. Courts examine multiple factors: the language of the contract (does it describe "goods sold" or "services rendered"?), the nature of the supplier's business (is the supplier primarily a manufacturer/retailer or a service provider?), the relative value allocated to goods versus services, and the basis of the complaint or breach. A minority of jurisdictions apply the gravamen test, which examines not the contract as a whole but the specific aspect of the transaction that is the source of the complaint. Under this approach, if the buyer's complaint relates to defective goods, Article 2 governs that issue even if the contract as a whole is predominantly for services. The MBE, however, overwhelmingly tests the majority predominant purpose approach.
Why It Matters — Key Doctrinal Differences Between Common Law and UCC
The classification of governing law is not an abstract exercise. It determines which set of substantive rules applies to every stage of the contracting process—from formation to performance to remedies. The following diagram and table illustrate the most significant divergences, many of which are frequently tested on the MBE and MEE.
As the diagram illustrates, the consequences of misidentifying governing law are substantial. Consider modification: under common law, an agreement to modify a contract requires fresh consideration—the pre-existing duty rule. Under UCC § 2-209, no new consideration is required so long as the modification is made in good faith. If an examinee applies the wrong body of law, the analysis of whether a valid modification occurred will be fundamentally flawed. Similarly, the acceptance rules diverge dramatically: where common law's mirror image rule treats any variant acceptance as a counteroffer, UCC § 2-207 permits a definite expression of acceptance to form a contract even when it includes additional or different terms—the so-called "battle of the forms."
Worked Example — Classifying a Contract
Consider the following fact pattern, representative of MBE-style questions: HomeOwner contracts with BuilderCo to renovate her kitchen. The contract states that BuilderCo will design and install custom cabinetry, granite countertops, and new appliances. The total contract price is $50,000, with $35,000 allocated to materials and appliances, and $15,000 to design and labor. A dispute arises when the countertops arrive with visible cracks. Which body of law governs?
Predominant Purpose Test vs. Gravamen Test
While the predominant purpose test is the majority approach and the one most frequently tested on the bar exam, it is important to understand its alternative. The gravamen test takes a fundamentally different approach to mixed contracts. Rather than applying a single body of law to the entire contract, the gravamen test looks at the specific source of the complaint or issue in dispute. If the complaint stems from a defect in the goods component, the UCC governs that issue; if it stems from deficient services, common law governs. This issue-specific approach has been adopted by a minority of courts, but most bar review materials—and the MBE—default to the predominant purpose test unless otherwise indicated.
| Feature | Predominant Purpose Test (Majority) | Gravamen Test (Minority) |
|---|---|---|
| Unit of analysis | The contract as a whole | The specific issue or complaint in dispute |
| Governing law outcome | One body of law governs the entire contract | Different bodies of law may govern different aspects of the same contract |
| Advantage | Predictability and simplicity; avoids applying two legal frameworks to one transaction | Tailored analysis; applies the more appropriate body of law to each issue |
| Disadvantage | May apply an ill-fitting body of law to one component (e.g., UCC perfect tender rule to a services issue) | Complexity; potential inconsistency in applying two sets of rules to one contract |
| Leading authority | Bonebrake v. Cox, 499 F.2d 951 (8th Cir. 1974) | Anthony Pools v. Sheehan, 455 A.2d 1002 (Md. 1983) |
| Bar exam default | Tested as the default approach | Rarely tested; may appear as a wrong answer choice |
Connections to Advanced Issues & Other UCC Articles
Once a student masters the Article 2 vs. common law distinction, several advanced issues emerge. First, Article 2 does not exist in isolation: the broader UCC contains articles governing leases of goods (Article 2A), negotiable instruments (Article 3), and secured transactions (Article 9), each with its own scope and definitions. Second, the international analog of Article 2—the United Nations Convention on Contracts for the International Sale of Goods (CISG)—applies to cross-border sales of goods between parties in signatory nations unless the parties expressly opt out. While the CISG is less heavily tested on the bar exam, understanding its existence is important for any contracts analysis involving international parties.
| Concept | Article 2 (Basic) | Advanced Extension |
|---|---|---|
| Scope | Sale of goods | Article 2A extends analogous rules to leases of goods; CISG governs international sales |
| Merchant rules | §§ 2-104, 2-205, 2-207, 2-209 | Article 2A also has merchant-specific provisions for lease transactions |
| Digital goods / SaaS | Uncertain; most courts treat as non-goods | Proposed UCITA (Uniform Computer Information Transactions Act) was withdrawn; no uniform statute governs software licenses |
| Mixed contracts | Predominant purpose test | Emerging question: should 3D-printed goods, which are manufactured on-site through a service process, be treated as goods or services? |
The digital economy poses particularly interesting challenges to the traditional goods/services dichotomy. When a consumer downloads software from the internet, there is no tangible, movable object—yet the transaction resembles a sale. When a business subscribes to a cloud-based Software-as-a-Service (SaaS) platform, the transaction has characteristics of both a license and a service agreement. These frontier questions are unlikely to appear on the current bar exam, but they illustrate why mastering the foundational classification framework is essential: as commerce evolves, the core analytical question—"Is this a transaction in goods?"—remains the starting point for every analysis.
Practice Problems
Lesson Summary
The threshold question in every contracts analysis on the bar exam is determining the governing body of law. UCC Article 2 governs contracts for the sale of goods—defined as all things that are movable at the time of identification to the contract. Common law governs everything else: services, real estate, employment, insurance, and intellectual property contracts. When a contract involves both goods and services (mixed contracts), the majority rule requires applying the predominant purpose test to determine which component—goods or services—forms the primary thrust of the agreement, and then applying that body of law to the entire contract.
Getting this classification right is outcome-determinative because the UCC and common law diverge on critical issues: the mirror image rule vs. § 2-207 for acceptance, consideration for modification vs. good faith, the $500 statute of frauds threshold, firm offers without consideration, gap-fillers for open terms, and the perfect tender rule vs. substantial performance. Always begin your contracts analysis by identifying the subject matter and selecting the correct legal framework before addressing any substantive issue.
