Tenn. Code Ann. § 54-12-117

If the county legislative body should not see fit to order the preliminary expenses be paid, and the parties to whom the expenses are owing are not willing to agree to wait until a fund for their payment can be provided by special assessments upon the district, then the county legislative body, by proper order, shall require the petitioner to pay to the county clerk a fund sufficient to pay the preliminary expenses, and the bond required of petitioners by this part shall be liable for the preliminary expenses, and judgment on the bonds may be rendered at any time by the county legislative body to the end the fund for expenses be provided, just as the county legislative body renders judgment on cost bonds, and one (1) judgment shall not prevent other judgments on the same bond, so the sum of the judgments does not exceed the penalty of the bond.
