Tennessee Code Title 66. Property § 66-24-122

(a) A deed or other instrument transferring ownership of real property, but not including a deed of trust or mortgage, shall indicate the parcel identification number assigned by the county assessor of property or a sworn affidavit that such information was requested from the assessor and was not furnished promptly. The registrar of deeds shall accept no deed or other such instrument for recordation unless such information or affidavit is contained on the deed or other such instrument.

(b) Nothing contained within this section shall be construed to affect the validity of the underlying transfer or conveyance. If a deed or other instrument is accepted for recordation which does not contain the required parcel identification number or affidavit as aforementioned, then the deed or instrument shall be recorded, and the absence of such number or statement shall in no way affect the preference, priority or legal validity of such deed or other evidence of transfer or the legal validity of the recording of the deed or instrument.

(c) Nothing contained within this section shall be construed to affect the validity of the underlying transfer or conveyance. If, through error of the registrar of deeds, a deed or other evidence is accepted for recordation and does not contain the required parcel identification number or derivation clause, then the deed or instrument shall be recorded, and the absence of such number or clause shall in no way affect the preference, priority or legal validity of such deed or other evidence of transfer.
