Formation and gap-filling under Article 2

The Article 2 Switch: Goods, Quantity, and the Live Issue

Article 2 formation asks whether the parties made a sale-of-goods contract despite informal communications, incomplete terms, conflicting forms, or shipment conduct. Begin by identifying movable goods as the subject; for a mixed goods-services transaction, use any supplied direction on which law governs rather than assuming Article 2. Then ask whether quantity is stated or objectively determinable, whether a response accepts or conditions assent, and whether the writings and conduct satisfy the applicable enforceability rule.

This topic is not starred: legal resources may be supplied when it is tested, and where they are not, you need only demonstrate recognition that the topic is at issue.

The Floor to Carry: The Fast Vocabulary of a UCC Problem

Hold these terms and relationships in usable form: merchant, definite and seasonable expression of acceptance, expressly conditional acceptance, additional term, different term, conduct recognizing a contract, output contract, requirements contract, reasonable price, reasonable time, seller’s place of business, single delivery, and merchant confirmation.

Run the questions in this order:

Is this a sale of goods, or has supplied law assigned a hybrid transaction elsewhere?
Is quantity stated or determinable through an output or requirements measure? Article 2 can fill many terms, but it ordinarily does not invent quantity.
Does the response accept, expressly condition assent, or merely invite further negotiation? Does shipment operate as acceptance, breach, accommodation, or counteroffer?
Do the writings satisfy the goods statute of frauds when its threshold is met? If forms conflict, apply the supplied Article 2 rule rather than the common-law mirror-image rule.
After identifying agreed terms, course evidence, and usage, which default supplies each genuine gap?

The Merchant Paper Trail: When Forms Accept and When They Do Not

Article 2 permits a contract to be made in any manner showing agreement, including conduct, and the moment of formation need not be identifiable. The important limiting point is quantity: an output or requirements quantity can be sufficiently definite if measured in good faith, but a court generally cannot enforce an agreement that supplies no workable quantity. A requirements buyer may not demand a quantity unreasonably disproportionate to an estimate or normal prior requirements unless the agreement permits it; an output seller likewise must act in good faith.

A purchase order for goods priced at $500 or more also raises the goods statute of frauds. The writing need only indicate that a contract for sale was made and be signed by the party against whom enforcement is sought, but enforcement is limited to the quantity stated. Between merchants, if a writing in confirmation of the contract, sufficient against the sender, is received within a reasonable time and the recipient has reason to know its contents, it satisfies the statute of frauds against the recipient unless the recipient gives written notice of objection to its contents within 10 days after receipt. Other routes can enforce the quantity actually admitted, paid for, or received and accepted, and specially manufactured goods can qualify when the statutory conditions are met. Do not demand every negotiated term in the writing.

Under the Article 2 shipment rule, an order or other offer to buy goods for prompt or current shipment ordinarily invites acceptance by a prompt promise to ship or a prompt shipment. A shipment of nonconforming goods generally accepts the offer and breaches it at the same time. The exception is a seasonably notified accommodation: the seller says the shipment is offered only as an accommodation, so it is not an acceptance of the original offer but a counteroffer.

Battle-of-forms problems turn on a narrow distinction. A definite, seasonable expression of acceptance operates as acceptance even with additional or different terms, unless the response is expressly conditional on assent to those terms. “We accept, but request…” is ordinarily an acceptance with a proposed addition. “We will accept only if you assent…” is expressly conditional and does not accept under that rule.

When the response is an acceptance, an additional term is generally only a proposal. Between merchants it enters the contract unless the offer limits acceptance to its terms, the term materially alters the bargain, or the recipient already objected or reasonably objects. A consumer’s silence does not convert the proposed term into a contract term. “Different terms” are a known danger zone: courts use differing approaches, so follow the supplied rule. Never silently substitute a common-law mirror-image analysis.

Once goods, quantity, and a response are identified, this narrow decision tree keeps the conditional-acceptance question in order:

Loading diagram…

Read a supplied rule by locating its operative language first: “operates as an acceptance,” “unless,” and “become part.” Then classify each fact under that language. In the item below, “expressly conditional” is absent, so the acknowledgment accepts; “between merchants” activates the second subsection; and a material alteration remains excluded even though the buyer stayed silent.

For this item, use this supplied provision:

UCC 2-207

(1) A definite and seasonable expression of acceptance or a written confirmation which is sent within a reasonable time operates as an acceptance even though it states terms additional to or different from those offered or agreed upon, unless acceptance is expressly made conditional on assent to the additional or different terms.

(2) The additional terms are to be construed as proposals for addition to the contract. Between merchants such terms become part of the contract unless: (a) the offer expressly limits acceptance to the terms of the offer; (b) they materially alter it; or (c) notification of objection to them has already been given or is given within a reasonable time after notice of them is received.

(3) Conduct by both parties which recognizes the existence of a contract is sufficient to establish a contract for sale although the writings of the parties do not otherwise establish a contract. In such case the terms of the particular contract consist of those terms on which the writings of the parties agree, together with any supplementary terms incorporated under any other provisions of this Act.

A hospital, a merchant, sent a signed purchase order to ValveCo, also a merchant, for 100 valves at $10 each. The order contained no cancellation provision. ValveCo promptly sent an acknowledgment stating, “We accept your order,” and adding, “If the buyer cancels for any reason, the seller may charge a cancellation fee equal to 20% of the purchase price.” The hospital did not object, and ValveCo shipped the valves.

The Default Term Map: Filling the Gap Without Rewriting the Deal

A gap filler applies only after separating agreed terms from genuinely omitted terms. Read the whole transaction: express language first, then course of performance, course of dealing, and usage of trade when relevant, and only then the statutory default. An added term in an acknowledgment is not the same thing as an omitted term; the former is governed by the battle-of-forms analysis, while the latter invites a default.

Missing question	Article 2 default	Fact that displaces it
Price	Reasonable price at delivery if the parties intended to be bound	Agreed price, agreed method, or intent not to be bound without price
Quantity	No invented quantity; use a good-faith output or requirements measure when shown	Stated quantity, estimate, or valid output or requirements formula
Place	Seller’s place of business or residence; identified goods that are in another place at the time of contracting use that place	Agreed destination or other delivery location
Time	Reasonable time	Stated deadline, shipment period, or reliable trade practice
Payment	Generally when and where the buyer receives the goods	Credit terms, documents, or separately accepted lots
Delivery pattern	Single delivery	Agreement or circumstances authorizing delivery in lots

For open price, the parties may intend to be bound while leaving price to agreement, a market, or one party acting in good faith. If the intended method fails, the reasonable price at the time for delivery ordinarily fills the gap. But if the parties expressly intend no contract unless price is fixed, there is no contract merely because a court can calculate a reasonable price.

Quantity is the sharpest near-miss. “Price to be agreed later” can be cured by a reasonable-price default; “100 units, price to be agreed later” is generally a contract if intent is present. “We will buy whatever our needs are” can supply quantity through good-faith requirements. “We may buy some units” usually does not.

The place default is not automatically a destination term. If no place is stated, look first to the seller’s business or residence, with identified goods that are in another place at the time of contracting as the important exception. A stated “FOB” or destination provision is an agreed allocation, not a gap. Similarly, a reasonable-time default does not erase a definite delivery date, and a payment default does not override negotiated credit.

The Timed Distinctions: Three Questions on Formation and Defaults

Practice

A retailer orders 50 blue chairs from a merchant supplier for prompt shipment. The supplier promptly ships 50 red chairs and sends a note stating, “These chairs are an accommodation because the blue chairs are unavailable.” What is the legal effect of the shipment?

A manufacturer agrees to sell a retailer 100 filters, stating that the parties intend to be bound but leaving the price “to be agreed later.” They never agree on a price, and the contract contains no market formula. Which price applies?

A buyer and seller contract for identified machinery without stating a delivery location. At formation, the machinery is in Chicago, although the seller’s only business office is in Boston. Where is delivery due?

High-Yield Points - ⚡ Biggest Takeaways

Quantity must be stated or objectively determinable; a reasonable-price default cannot invent it. A definite acceptance with an added term forms the contract, but a material addition may stay outside it. A nonconforming shipment is acceptance and breach unless the seller seasonably identifies it as an accommodation.

Practice Questions: Formation and gap-filling under Article 2

2. Using only the supplied client file and legal resources, prepare an advisory letter to the client assessing whether the client can compel the seller to complete the land sale. Explain the writing requirement, the financing condition, available remedies, litigation risks, and the most appropriate immediate next step.

3. A building contractor asked a steel supplier for a price on 100 standard steel beams needed for a project. The supplier, a merchant in steel products, sent a signed email stating, “We offer 100 beams at $900 each and will hold this offer open for 5 months.” The contractor gave no consideration for that assurance. Relying on the quoted price, the contractor submitted a project bid that same afternoon but did not notify the supplier of the bid. Ten days later, before the contractor accepted, the supplier emailed a revocation because steel prices had increased. The contractor received the revocation immediately and attempted to accept the original offer the next day. Which of the following is the contractor's strongest argument that a contract was formed?

A. The contractor may enforce the promise because its foreseeable reliance substituted for acceptance of the supplier's offer.
B. The contractor may enforce the promise because a signed merchant firm offer is irrevocable for the stated period, capped at three months, and the revocation came well within that three-month window.
C. The supplier revoked effectively because the contractor gave no consideration to keep the offer open for 5 months.
D. The supplier could revoke because the assurance exceeded three months, so the firm-offer protection was void from the start.

Show answer

Answer: B. The contractor may enforce the promise because a signed merchant firm offer is irrevocable for the stated period, capped at three months, and the revocation came well within that three-month window.

The contractor may enforce the promise because a signed merchant firm offer is irrevocable for the stated period, capped at three months, and the revocation came well within that three-month window. - The supplier was a steel merchant whose signed email offered goods and expressly promised to hold the offer open, satisfying the UCC firm-offer rule without consideration. - Although the five-month assurance is capped at three months of irrevocability, the supplier tried to revoke after only ten days, so the contractor’s acceptance the next day formed a contract. The contractor may enforce the promise because its foreseeable reliance substituted for acceptance of the supplier's offer. - Submitting the project bid was not acceptance of the supplier’s offer, and the contractor did not notify the supplier of the bid. - Reliance may support a separate argument for relief, but the signed merchant firm offer supplies the stronger basis for treating the next day’s acceptance as effective. The supplier revoked effectively because the contractor gave no consideration to keep the offer open for 5 months. - A qualifying merchant firm offer is irrevocable without consideration for up to three months. - The lack of consideration prevents enforcement of the full five-month assurance under that rule, but it did not make the revocation after ten days effective. The supplier could revoke because the assurance exceeded three months, so the firm-offer protection was void from the start. - The three-month cap limits how long the signed assurance makes the offer irrevocable; it does not void that protection from the start. - Because the supplier’s revocation arrived only ten days after the offer, it fell within the protected period.

4. Using only the supplied file and legal resources, prepare a confidential negotiation memorandum for the supervising attorney and client. Evaluate whether BrightLeaf could assign royalty-payment rights or delegate editing and marketing duties to PageTurn Media, whether Ortiz must accept PageTurn's performance, and whether BrightLeaf's communications amount to repudiation. Recommend negotiation objectives, concessions, information requests, and protective terms that preserve the book's launch while addressing Ortiz's financial and performance concerns.

5. Using only the supplied file and legal resources, draft a persuasive settlement letter to counsel for Metro Packaging concerning FreshField Foods' purchase of 10,000 glass jars. State FreshField's supportable damages demand, explain which claimed losses are recoverable or vulnerable, address Metro's arguments about the limitation clause, foreseeability, certainty, and mitigation, and propose a commercially reasonable settlement structure. Do not threaten unsupported remedies or rely on outside law. The client wants prompt reimbursement while preserving the supplier relationship if adequate quality controls are adopted. Include a concise factual introduction, legal analysis, quantified demand, response to counterarguments, and a practical proposal for payment and future performance.

7. On March 1, a machine manufacturer sent a signed email to a retailer offering to sell 20 standard generators for $8,000 each. The email stated, "This offer will remain open through April 15." Both parties regularly deal in generators. The retailer gave no consideration for the promise to keep the offer open. On March 20, the manufacturer emailed, "Market prices have increased, so I withdraw my offer." The retailer received that message immediately. On March 25, the retailer emailed an unconditional acceptance of the March 1 terms. The manufacturer refused to deliver, asserting that the offer had been revoked. The retailer asks whether an enforceable contract was formed. Which of the following is the most appropriate advice?

A. A contract was formed because the signed merchant's assurance made the offer irrevocable when the retailer accepted within the stated period.
B. No contract was formed because an offeror may revoke any unaccepted offer unless the offeree paid consideration for an option.
C. No contract was formed because the retailer did not accept before the manufacturer communicated its attempted revocation.
D. A contract was formed only if the retailer can prove foreseeable reliance on the promise that the offer would remain open.

Show answer

Answer: A. A contract was formed because the signed merchant's assurance made the offer irrevocable when the retailer accepted within the stated period.

A contract was formed because the signed merchant's assurance made the offer irrevocable when the retailer accepted within the stated period. - Generators are goods, and the manufacturer’s signed email assuring that the offer would remain open through April 15 was a merchant’s firm offer under UCC Article 2. - The March 20 withdrawal was ineffective during that period, so the retailer’s unconditional March 25 acceptance formed a contract for 20 generators at $8,000 each. No contract was formed because an offeror may revoke any unaccepted offer unless the offeree paid consideration for an option. - Although an ordinary offer generally can be revoked before acceptance, UCC Article 2 makes a qualifying merchant’s firm offer irrevocable without consideration. - The retailer’s failure to pay for an option therefore did not permit withdrawal of the manufacturer’s signed offer before April 15. No contract was formed because the retailer did not accept before the manufacturer communicated its attempted revocation. - The retailer received the withdrawal on March 20 and accepted on March 25, but the signed assurance protected the offer through April 15. - Because the attempted revocation was ineffective, acceptance did not have to precede the March 20 message. A contract was formed only if the retailer can prove foreseeable reliance on the promise that the offer would remain open. - Reliance is not required to enforce a merchant’s firm offer satisfying UCC Article 2’s requirements. - The manufacturer’s signed assurance kept the offer open, and the retailer accepted its terms on March 25 without needing to prove any change of position.

8. A collector signed a written offer promising to sell a rare watch to a buyer for $18,000. The writing stated, "I will keep this offer open until Friday at 5:00 p.m." The buyer gave no consideration for that promise. On Thursday morning, a reliable mutual acquaintance told the buyer that the collector had sold the watch to another person. The collector had not directly communicated with the buyer. On Thursday afternoon, the buyer emailed an acceptance, which the collector received immediately. The transaction is a sale of goods, but the collector is not a merchant in watches. Which of the following best states whether a contract was formed?

A. A contract was formed because a signed promise to keep an offer open creates an option without consideration.
B. A contract was formed because only a revocation communicated directly by the offeror can terminate an offer.
C. No contract was formed because reliable information of the sale indirectly revoked the offer before acceptance.
D. No contract was formed because an offer to sell goods may be accepted only by tendering payment.

Show answer

Answer: C. No contract was formed because reliable information of the sale indirectly revoked the offer before acceptance.

No contract was formed because reliable information of the sale indirectly revoked the offer before acceptance. - The reliable mutual acquaintance’s report that the collector had sold the watch gave the buyer notice of definite action inconsistent with the offer, indirectly revoking it on Thursday morning. - The buyer’s email arrived Thursday afternoon, after the offer had been revoked, so it could not form a contract. A contract was formed because a signed promise to keep an offer open creates an option without consideration. - The collector’s promise to keep the offer open until Friday lacked the consideration needed to create an option contract. - A signed offer to sell goods can be irrevocable without consideration under the merchant firm-offer rule, but the collector was not a merchant in watches. A contract was formed because only a revocation communicated directly by the offeror can terminate an offer. - Revocation need not come directly from the collector when the buyer learns from a reliable source that the collector has sold the watch. - That information reached the buyer Thursday morning, before the buyer emailed an acceptance. No contract was formed because an offer to sell goods may be accepted only by tendering payment. - The written offer did not require tender of the $18,000 as the method of acceptance; an emailed acceptance could ordinarily suffice. - No contract formed because the offer had already been indirectly revoked, not because the buyer failed to tender payment.

Flashcards: Formation and gap-filling under Article 2

1. What is the common-law mirror-image rule, and what is the effect of a nonconforming response to an offer?

Show answer

Under the majority common-law rule, acceptance must match the offer’s terms exactly; a response adding or changing terms is generally a counteroffer, not an acceptance. A mere inquiry or request that does not condition assent on the new term is not a counteroffer.

2. When does an acceptance become effective under the mailbox rule, and what are its principal exceptions?

Show answer

Under the majority mailbox rule, an acceptance is effective when properly dispatched, unless the offer requires receipt, the acceptance is sent after a prior rejection, or the offer is an option contract. For an option contract, acceptance generally becomes effective only upon receipt.

3. What is the preexisting-duty rule for consideration?

Show answer

A promise to perform a duty the promisee already owes the promisor is not new consideration because it adds no legal detriment or benefit. The rule generally does not apply when the duty is owed to a third party or when unforeseen circumstances support a fair modification under the applicable law.

4. What is required to accept an offer for a unilateral contract under the Restatement majority rule?

Show answer

The offeree must complete the requested performance; beginning performance creates an option contract under Restatement § 45, but it does not itself complete acceptance or form the underlying contract.

5. What standard determines whether a party manifested intent to enter a contract?

Show answer

The majority rule applies an objective standard: intent is determined by the party’s outward words and conduct as reasonably understood by the other party, not by undisclosed intent.

6. What makes an offer sufficiently definite under the common law?

Show answer

The offer must identify the parties, subject matter, and essential terms with enough certainty for a court to determine breach and provide a remedy; typically, price, quantity, and time are required when material.

7. When can silence operate as acceptance of an offer?

Show answer

Silence ordinarily is not acceptance, but it may operate as acceptance when the offeree takes the benefit of offered services with a reasonable opportunity to reject, the parties’ prior dealings establish that silence means assent, or the offeree indicates that silence will constitute acceptance and intends that result.

8. How are advertisements and other general solicitations ordinarily treated in contract formation?

Show answer

Under the majority rule, they are invitations to make offers rather than offers because they usually lack commitment and definite terms. An advertisement can be an offer if it is clear, definite, explicit, and leaves nothing open for negotiation.

9. Why is an illusory promise insufficient consideration?

Show answer

A promise is illusory when it does not actually bind the promisor, such as a promise to buy only if the promisor chooses to do so. Because no legal detriment is exchanged, it cannot serve as consideration for the other party’s promise.

10. What events terminate the power of acceptance before acceptance occurs?

Show answer

Under the majority rule, the power of acceptance ends by rejection or counteroffer, lapse of the stated or reasonable time, revocation communicated to the offeree, or death or incapacity of either party.
