Which of the following is NOT required for a deed to be valid in Connecticut?

In Connecticut, for a deed to be valid, it is not necessary for the grantee to sign the deed. The essential requirements focus primarily on the grantor, who must sign the deed for it to effectively transfer ownership. The grantor's signature is crucial because it represents the intention to convey the property.

While the deed must be duly executed and typically requires acknowledgment, the signature of a witness is not a mandated condition for validity, though it can provide an additional layer of authenticity. The acknowledgment, which is the notarization of the grantor's signature, is important for the deed to be recorded in the land records, but it does not affect the basic validity of the deed itself.

Thus, the grantee's signature is not a legal requirement for the deed's validity in Connecticut, making it the correct answer for what is NOT required.
