(1) No lands or tenements shall be sold by virtue of any execution unless such sale is at public venue and between the hours of nine in the morning and the setting of the sun on the same day nor unless the time and place of holding such sale has been previously advertised for the space of twenty days, by publishing notices of the time and place thereof in some daily or weekly newspaper printed and published in the county where such lands and tenements are situate or, if there is no such newspaper printed in the county, by posting such notices, printed or written, or partly printed and partly written, in three of the most public places in the county where the lands may be situated specifying the names of the plaintiff and defendant in the execution. In all such notices, the lands or tenements to be sold shall be described with reasonable certainty by setting forth their number or by some other appropriate description, and such notices shall comply with section 24-70-109, C.R.S.

(2) If any sheriff or other officer sells any lands or tenements by virtue of any such execution, otherwise than in the manner aforesaid, or without such previous notice, the sheriff or other officer so offending shall forfeit and pay the sum of fifty dollars for every offense to be recovered, with costs of suit, in any court of record in this state by the person whose lands were advertised and sold. No such offense nor any irregularity on the part of the sheriff or other officer having the execution shall affect the validity of any sale made under it, unless it appears that the purchaser had notice of such irregularity.
