Chapter 3. Formation of a Contract under the UCC
3.1. Common Law Principles of Contract Formation. Common law has developed principles
governing formation of a contract, including the requirement of mutual assent between the
parties manifested through an offer and acceptance. Early in its development, the common law
was strict, making it difficult at times to form a contract.
3.1.1. Under the early mirror image rule, the terms of the acceptance had to exactly
mirror the terms of the offer in order for a contract to be formed. Furthermore, the manner
of acceptance (promise or performance) had to be the same, as did the medium of
acceptance (letter, telegraph, etc.). For example, if an offer to sell a horse was delivered to
a potential buyer in a telegram, the buyer could accept the offer only by telegram, and not
by letter and not by performance. However, even before the UCC was adopted, these
strict rules of contract formation were being relaxed by the courts and legislatures. See,
offer was sufficient to form a contract). Reflecting current common law, the Restatement
(Second) of Contracts § 30 (1981) provides: “Unless otherwise indicated by the language
or the circumstances, an offer invites acceptance in any manner and by any medium
reasonable in the circumstances.”
3.1.1.1. Even though common law has relaxed the rules of offer and acceptance,
many courts require a “mirror image” acceptance of the terms proposed. In other
words, a purported acceptance is not effective if it adds new or differing terms
from those proposed; instead, it is a counter-offer. See Restatement (Second) of
Contracts § 59 (1981): “A reply to an offer which purports to accept it but is
conditional on the offeror’s assent to terms additional to or different from those
offered is not an acceptance but is a counter-offer.” If a seller offers to sell a horse
for $2,000, and the buyer replies, “It’s a deal if you include the bridle,” then there
is no acceptance. The buyer’s response is a counter-offer.
3.1.2. At common law, a contract cannot be formed if essential terms are missing. In
determined that a letter regarding the lease of property did not form a contract. Although
the letter referenced the lease of a specific property and the rental amount, it did not
specify the commencement date of the lease or the responsibility of the parties for taxes,
insurance, repairs, maintenance and utilities. In addition, the letter provided for renewal
terms, but failed to specify the rental amount for the renewal periods.
3.2. Relaxed Formation Rules under the UCC. As noted by the Montana Supreme Court in
Conagra, Inc. v. Nierenberg, 7 P.3d 369, ¶ 28 (Mont. 2000), “the UCC rules governing sales
agreements are far more permissive in this respect than the general common law rules governing
contract formation.” The party trying to avoid a contract for the sale of grain argued that there
