Any such plat may be vacated by the proprietors thereof at any
time before the sale of any lots therein, by a written
instrument declaring the same to be vacated, duly executed,
acknowledged or proved and recorded in the same office with the

out or described in such plat, and in case where any lots have
been sold, the plat may be vacated as herein provided, by all
the owners of lots in such plat joining in the execution of the

provided without the approval of the city or town. No plat or
portion thereof for which a subdivision permit has been obtained
pursuant to W.S. 18-5-304 shall be vacated as herein provided
