Here is the Tennessee law on recording a materialmans lien: "In order to preserve the priority of the lien provided by this chapter as of the date of its attachment, as concerns subsequent purchasers or encumbrancers for a valuable consideration without notice of the lien, though not as concerns the owner, the lienor, who has not recorded the lienor's contract pursuant to § 66-11-111, is required to record in the office of the register of deeds of the county where the real property, or any part affected, lies, a sworn statement of the amount for, and a reasonably certain description of the real property on, which the lien is claimed. The recording party shall pay filing fees, and shall be provided a receipt for the filing fees, which amount shall be part of the lien amount. Recordation is required to be done no later than ninety (90) days after the date the improvement is complete or is abandoned, prior to which time the lien shall be effective as against the purchasers or encumbrancers without the recordation."
§ 66-11-112. Sworn statements; notice; abandonment.
