Tennessee Code Title 66. Property § 66-11-114

(b)(1) The right to repossess and remove the materials shall not be affected by their sale, encumbrance, attachment or transfer from the site of the improvement subsequent to delivery to the site, except that the right to repossess shall not be effective as against a purchaser or encumbrancer of the materials in good faith whose interest in the materials arose since removal from the site of the improvement, or as against a creditor attaching after the removal.

(2) The right of repossession and removal given by this section shall extend only to materials whose purchase price does not exceed the amount remaining due to the person repossessing; but where materials have been partly paid for, the person delivering them may repossess them as allowed in this section on refunding the part of the purchase price that has been paid.
