Final answer:
A valid deed must refer to an identifiable grantee, which means the grantee must be clearly specified. The grantee does not need to be competent, over 21, or intestate for the property transfer to be valid.
Step-by-step explanation:
In the context of real estate and property law, a valid deed must refer to a grantee who is identifiable. This means that the grantee, which is the person receiving the property, must be sufficiently specified in the deed so that they can be recognized or identified.
It is not necessary for the grantee to be competent, over 21 years old, or intestate to be the recipient of the property through a deed. It is important to note that the term intestate refers to a condition wherein a person has passed away without a will, implicating that state's intestacy laws will dictate how their assets are distributed. However, this condition applies to the decedent and is not a requirement for a grantee in a property transaction.
