A contractual provision whose inclusion in a signed writing is required to satisfy the statute of frauds or to show effective manifestation of assent when fraud concerning the document is later alleged.
Emma Erickson met with her lawyer Eugene Ellsworth to discuss selling her company to him. Ellsworth prepared a purchase agreement but omitted any writing in which Erickson consented to the price, payment terms, and his dual role as buyer and counsel. When Erickson later sought to rescind, the absence of signed consent to those essential terms prevented enforcement of the transaction under the professional conduct rules.
Edgar Evers signed a one-page memo agreeing to sell his warehouse to Emerald Enterprises for a stated price. The memo identified the property and parties but omitted any description of the closing date or financing obligations. Emerald sued for specific performance, yet the court held the memo failed to state the essential terms of the unperformed promises with reasonable certainty.

Elijah Edwards was handed a promissory note by a seller who falsely described it as a receipt for goods. Edwards signed without reading the document and without any chance to learn its payment terms or interest rate. When the holder sought enforcement, Edwards raised the defense that fraud had concealed the instrument's essential terms.
Esme Ellington was presented with a multi-page services agreement that a counterparty described only as a standard form. Ellington signed after being told the document contained no new obligations beyond prior discussions, but the writing actually altered payment schedules and liability limits. Because Ellington had neither knowledge nor opportunity to learn the essential terms, her signature did not manifest assent.
A seller handed a buyer a document described only as a receipt. The buyer signed without reading or opportunity to learn that the writing was actually a promissory note containing payment and interest terms. When enforcement was later sought, the signature was held ineffective as a manifestation of assent because fraud had concealed the essential terms.
An essential term is one whose inclusion is required for the contract to exist at all or to satisfy the statute of frauds. Its omission leaves the promises too uncertain to enforce, whereas a material term may be supplied by the court under gap-filler rules once the parties have manifested assent.

The statute requires only that the writing state the essential terms of the unperformed promises with reasonable certainty. Ancillary details such as exact closing procedures may be supplied by course of dealing or reasonable implication once the core obligations are identified.

Rule 1.8(a)(3) demands that the client give informed consent in a signed writing to the essential terms of the transaction and the lawyer's role. Without that consent the transaction is presumptively voidable regardless of fairness.

Yes. Under UCC § 3-305(a)(1)(iii) and Restatement (Second) of Contracts § 163, fraud that prevents the signer from knowing the character or essential terms of the instrument means the signature is not effective as a manifestation of assent, producing a void rather than merely voidable obligation.
