Iowa Code § 499A.9
Any cooperative organized under this chapter may change its name or amend its articles of incorporation by a vote of a majority of the members, in such manner as may be provided in its articles; but if no such provision is made in the articles the same may be amended at any regular meeting or special meeting called for that purpose by the president or secretary or a majority of the board of directors. Notice of any meeting at which it is proposed to amend the articles of incorporation, shall be given by mailing to each member at the member's last known post office address at least ten days prior to such meeting, a notice signed by the secretary setting forth the proposed amendments in substance, or by two publications of said notice in some daily or weekly newspaper in general circulation in the county wherein said cooperative has its principal place of business. The last publication of said notice shall be not less than ten days prior to the date of said meeting. There shall be paid to the secretary of state at the time of the filing of such change or amendment a recording fee of fifty cents per page.
