Final answer:
The essential element of a valid North Carolina deed is words of conveyance, which establish the intent to transfer property and are crucial for the deed's legality.
Step-by-step explanation:
The essential element of a valid North Carolina deed that must be present is words of conveyance. A deed is a legal document used to transfer real estate from one person (the grantor) to another (the grantee). The deed must include certain formal elements to be considered valid. While a seal and recordation of the deed may provide evidence of its validity, they are not required for the deed to be effective. Furthermore, the signature of the grantee is not a necessary element for a valid deed. Therefore, it is the words of conveyance that establish the intent to transfer the property, and this is the crucial element needed to ensure the deed is legally operative.
