N.M. Stat. § 58-10-24
The annual meeting of the members of each association shall be held each year at the time fixed in the bylaws of the association. Special meetings may be called as provided in the bylaws. Members entitled to vote at any meeting of the members are those who were members of record at the end of the calendar month next preceding the date of the meeting except those who have ceased to be members. The bylaws of an association having permanent capital stock may provide that only members who are holders of the stock are entitled to vote. In the absence of such bylaw, in the determination of all questions requiring action by the members, each member is entitled to cast one vote by virtue of his membership, plus an additional vote for each share or fraction thereof of the permanent capital stock of the association, if any, owned by the member, plus an additional vote for each one hundred dollars ($100) or fraction thereof of the withdrawal value of savings accounts, if any, held by the member, but no member shall cast more than fifty votes based upon the withdrawal value of his savings account. A loan or a savings account creates a single membership for voting purposes even though more than one person is obligated on the loan or has an interest in the savings account. Voting may be in person or by proxy. Every proxy shall be in writing and signed by the member or his attorney in fact and, when filed with the secretary, unless otherwise specified in the proxy, continues in force from year to year until a revocation in writing is delivered to the secretary or until superseded by subsequent proxies. The bylaws of each association shall specify the quorum requirements and other voting requirements for conducting business at membership meetings.
