No consolidation of contiguous municipalities may be considered unless fifteen percent of the registered voters of the municipality, based upon the total number of registered voters at the last preceding general election, desiring to be annexed to another who are also named as owners of real property in the tax list of the last preceding year, shall file with the municipal finance officer a petition requesting consolidation. When such petition has been filed the governing bodies of the municipalities concerned shall meet and fix the terms upon which the proposed annexation shall be made. If both governing bodies agree upon the proposed terms, they shall by identical resolutions so declare.
