Emily Ellis, a solo practitioner, wants to buy a commercial building from her longtime client Edward Everett.

Echo Systems orally agrees to buy custom software from Eclipse Manufacturing for $75,000 with delivery in nine months.

Ezra Eastman signs a promissory note believing it is a receipt for equipment repair. The payee had substituted a note with different interest and maturity terms.

Edith Eberhardt meets with Equinox Energy to sign a solar-panel lease. The salesperson hands her a document and states it is only a preliminary survey form. Eberhardt signs without reading the fine print that actually creates a twenty-year binding obligation. Because the misrepresentation concerned the essential terms, her signature does not manifest assent.
Courts look to whether the term is necessary to identify the parties, subject matter, and the core unperformed promises so that the agreement can be enforced without resort to parol evidence for those elements. Price, quantity, and duration are frequently treated as essential, but the determination is fact-specific and depends on the type of contract.

Rule 1.8(a)(3) requires the client to give informed consent in a signed writing to the essential terms of the transaction and the lawyer's role in it. The rule does not demand disclosure of every ancillary detail, but the core commercial terms and the lawyer's conflicting position must be clear.

UCC § 3-305(a)(1)(iii) provides a real defense to enforcement of a negotiable instrument when fraud induced the obligor to sign without knowledge or reasonable opportunity to learn the instrument's character or essential terms. Unlike ordinary fraud, which is usually only a personal defense, this real defense cuts off even a holder in due course.
