A petition for the change of name of any township, town, or city may be filed in the district court of such county, signed by a majority of the legal voters of such body, setting forth the cause why such change is desirable and the name to be substituted. The court, upon being satisfied by proof that the prayer of the petitioners is just and reasonable, that notice as required in the foregoing section has been given, that the petitioners are legal voters of such township, town, or city and that they desire the change, and that such change will not result in an objectionable confusion of names within the state, may order the change prayed for in such petition.
