Final answer:
A valid deed requires that the grantor be of sound mind, but the buyer's mental state is not a requirement for the deed. The grantee's signature is not a necessity for the validity of the deed; it is the grantor's signature that is crucial.
Step-by-step explanation:
What Makes a Valid Deed
In the context of property law, a valid deed must meet several requirements. First, the grantor (seller) must have the legal capacity to transfer the property, which includes being of sound mind. However, the buyer's sound mind is not a requirement for the deed itself. The grantee (buyer) does not have to be of legal age; a minor can own property. The grantee's signature is generally not required on the deed for it to be valid; it is the grantor's signature that is essential. The deed must also accurately describe the person involved in the transaction, which means they must be a real person or a legally recognized entity. Therefore, the correct option is (d) Be a real person, though (a) Buyer of sound mind is also a factor in general contract law to determine the validity of an agreement. However, it is not specifically required for the deed to be valid.
