Formation questions often turn on timing and objective manifestations of assent. The safest method is to identify the governing law, then track offer, termination, and acceptance events in chronological order.
Practice in Testify →Choose common law or Article 2 first. Identify whether a valid offer exists, whether it remained open, and how acceptance could occur. Then apply the timing rule to the method actually used. If forms conflict under the UCC, separate contract formation from which additional or different terms become part of the agreement.
Students frequently apply the mailbox rule to option contracts or assume every changed term is a rejection. Another trap is overlooking whether an advertisement, price quote, or preliminary negotiation was definite enough to constitute an offer.
Write a short timeline: offer, attempted revocation, acceptance dispatch, acceptance receipt, and any intervening communication. Formation becomes much easier once the timing is visible.
In a Contracts course, professors may ask for several alternative theories of formation. Explain what happens under each plausible characterization rather than forcing ambiguous facts into one label.
For bar review, mix common-law and UCC formation questions. Before analyzing assent, always identify whether the transaction is primarily for goods or governed by common-law contract principles.
