Which of the following is NOT a requirement for a valid deed?

A deed is a formal document that conveys ownership of real property, and for it to be valid, certain requirements must be met. Among these, the signature of the grantor ensures that the person transferring the property consents to the transfer. Delivery refers to the intention of the grantor to convey the property rights, which is fundamental; without delivery, there is no valid transfer. The legal description of the property is also crucial because it explicitly identifies what is being conveyed, preventing ambiguity regarding the property involved.

While acknowledgment, which typically refers to the process of having the deed notarized or witnessed to prove that the grantor signed it willingly, can provide additional assurance of authenticity and help in public record keeping, it is not a strict requirement for the deed to be valid. Therefore, the absence of acknowledgment does not invalidate a deed as long as the other essential conditions are satisfied. This distinction highlights why acknowledgment is the correct choice for something that is not a necessity for the validity of a deed.
