Tenn. Code Ann. § 66-11-132: Consolidation of proceedings

If separate complaints, petitions, or civil warrants to enforce liens provided by this chapter are brought in the same court, then they must be consolidated; and if in different courts, the proceedings may, upon application, be removed into the court, if a court of record, in which the first complaint, petition, or civil warrant was filed, and there consolidated, unless the later proceeding is one for the benefit of all lienors, in the nature of a lien-creditors' bill, in which event earlier proceedings not of that nature must be consolidated into the lien-creditors' bill, on petition.
