Under the statute of frauds, which requirement is NOT necessary for Henry's real estate offer to be enforceable?

For a real estate offer to be enforceable under the statute of frauds, it indeed must meet certain requirements. The correct choice points out that notarization of the contract is not a necessary requirement for enforceability. The statute of frauds primarily requires that contracts for the sale of real estate must be in writing, signed by the party to be charged, and must include clear terms that outline the agreement between the parties.

Notarization may serve as a method of verification or authentication but does not affect the validity of the contract itself. Consequently, a real estate offer can be enforceable if it fulfills the written and signature requirements along with having clear terms, even if it hasn't been notarized. This distinction is important for understanding the legal requirements surrounding real estate transactions.
