There shall be one form of civil action. The first pleading on the part of the plaintiff shall be known as the complaint and shall contain a statement of the facts constituting the cause of action and, on a separate page of the complaint, a demand for the relief, which shall be a statement of the remedy or remedies sought. When money damages are sought in the demand for relief, the demand for relief shall set forth: (1) That the amount, legal interest or property in demand is fifteen thousand dollars or more, exclusive of interest and costs; or (2) that the amount, legal interest or property in demand is two thousand five hundred dollars or more but is less than fifteen thousand dollars, exclusive of interest and costs; or (3) that the amount, legal interest or property in demand is less than two thousand five hundred dollars, exclusive of interest and costs. In addition, in a contract action in which only money damages are sought and in which the amount, legal interest or property in demand is less than fifteen thousand dollars, exclusive of interest and costs, the demand for relief shall also set forth whether or not the remedy sought is based upon an express or implied promise to pay a definite sum.
