Section 18-1800. Change of name

The name of a village may be changed upon
  the adoption of a proposition therefor at an annual or special election.
  The proposition must contain the proposed new name, and  be  accompanied
  by written notice to the United States Postal Service of such change. If
  the  proposition be adopted a certificate thereof, attested by the mayor
  and clerk of the village, shall, within ten days after the election,  be
  filed  in the office of such clerk, in the office of the county clerk of
  each county in which any part of the village is situated,  and  also  in
  the  office  of  the secretary of state. The change of name takes effect
  upon the filing of the certificate in the office of the village clerk.
