The General Assembly determines the chancery court's jurisdiction, and may increase, decrease, or alter its jurisdiction. Tenn. Const., art. VI, § 8. Chancery courts "shall have all the powers, privileges, and jurisdiction properly and rightfully incident to a court of equity." T.C.A. § 16-11-101.  This inherent jurisdiction is original and exclusive in cases of an equitable nature, where the debt or demand exceeds $50, unless otherwise provided.  It lacks jurisdiction in cases where the debt or demand is less than $50, unless otherwise specifically provided. T.C.A. § 16-11-103. Although this inherent jurisdiction is exclusive, if no objection to jurisdiction is made, a circuit court may hear and determine such suits or may transfer the suit to chancery court.  T.C.A. § 16-10-111.
