Corporate Shareholder Agreement Governance-Override Requirements in New Mexico
At a glance
| Governing law, entity, agreement, and override scope | Ordinary domestic for-profit corporation; no omnibus agreement override. Articles may redirect board powers and duties; separate agreement statute reaches share voting only (NMSA 1978 §§ 53-11-2, -34(B), -35(A), 53-12-2) |
|---|---|
| Permitted subjects, statutory limits, and public policy | Articles may direct management, regulate affairs and internal affairs, define/limit/regulate corporation, director, shareholder or class powers, restrict transfers, and include bylaw-permitted provisions, all subject to consistency with law (§ 53-12-2(B)-(D)) |
| Eligible holders, owners, incorporators, and subscribers | Articles route is corporate charter architecture, not an all-holder agreement; original articles use one or more incorporators. Shareholder means record holder; no beneficial-owner or prospective-holder agreement route stated (§§ 53-11-2(E)-(F), 53-12-1) |
| Instrument, corporate party, knowledge, and consideration | Board-power allocation must be in articles; bylaws may regulate management only consistently with law and articles. Written voting agreements are valid and specifically enforceable but do not supply omnibus effect (§§ 53-11-27, -34(B), -35(A), 53-12-2) |
| Initial approval, signature, unanimity, class, and board rules | Original articles signed/delivered by one or more incorporators; no all-shareholder signature rule. No-shares amendment is board-only; issued-share amendment requires board proposal plus shareholder vote (§§ 53-12-1, 53-13-2(A)) |
| Amendment, revocation, extension, successors, and threshold | Articles amendment ordinarily requires majority of all entitled shares plus majority of each entitled class; charter may require more. Pre-June 17, 1983 private corporations retain former two-thirds rules until articles opt in (§§ 53-13-2(C), 53-18-6, -6.1(A)) |
| Duration, renewal, legacy agreements, and termination | Articles provision remains until lawfully amended; no fixed term, renewal, successor-holder, public-market cutoff, or omnibus-agreement legacy rule stated. Separate voting trust, not voting agreement, has 10-year maximum (§§ 53-11-34, 53-13-1 to -2) |
| Certificate or statement notice, recall, delivery, and validity | No special governance-agreement certificate legend, uncertificated statement, recall, delivery, or validity rule; the corporation-binding terms reside in publicly filed articles (complete Business Corporation Act; §§ 53-12-1 to -3, 53-13-4 to -5) |
| Purchaser knowledge, rescission, deadlines, and contract remedies | No omnibus purchaser-knowledge or rescission package. Voting agreements are specifically enforceable; no statutory rescission clock or contract-remedy rule is supplied for the articles route (§ 53-11-34(B)) |
| Public status, transferred power, liability, and boundaries | No public-status cutoff or agreement-based shareholder-liability shield. Articles may assign board powers/duties to named persons; statute does not expressly shift director liability to them. Ordinary director standards and limited articles exculpation remain (§§ 53-11-35, 53-12-2(E)) |
Requirements one by one
New Mexico uses articles, not an omnibus shareholder agreement
The board is the statutory starting point: it exercises corporate powers and directs the business and affairs. The Act then allows the articles of incorporation to provide otherwise and to identify the person or persons who exercise or perform specified board powers and duties (NMSA 1978 § 53-11-35(A)).
That is corporation-binding charter architecture. Section 53-11-34(B) separately makes agreements about voting shares valid and specifically enforceable, but it does not say that such an agreement displaces board authority or inconsistent Business Corporation Act rules.
The articles menu is broad but remains subject to law
The articles may direct management, regulate corporate affairs, define, limit, and regulate the powers of the corporation, directors, shareholders, or a class, restrict share transfers, and include provisions otherwise permitted in bylaws. They may also contain an incorporator-selected provision regulating internal affairs. Each route remains limited to provisions consistent with law (NMSA 1978 § 53-12-2(B)-(D)).
Bylaws are subordinate. The board adopts them and retains amendment power unless the articles reserve that power to shareholders; bylaw regulation of management cannot conflict with law or the articles (NMSA 1978 § 53-11-27).
Adoption and later amendment do not use a special unanimity rule
One or more persons or a domestic or foreign corporation may act as incorporator by signing and delivering the original articles and a copy. The original articles therefore do not require every current or prospective shareholder to sign (NMSA 1978 § 53-12-1).
After shares issue, the board proposes an articles amendment and submits it to shareholders. The ordinary rule is a majority of all shares entitled to vote, plus a majority of each class entitled to vote separately. If no shares have issued, the board adopts the amendment without shareholder action (NMSA 1978 §§ 53-13-1 to 53-13-3).
The articles may require a greater vote. A private corporation already in existence on June 17, 1983, also remains under the former two-thirds thresholds until it amends its articles to accept the 1983 simple-majority rules (NMSA 1978 §§ 53-18-6, 53-18-6.1(A)).
New Mexico does not add the Model Act notice and purchaser package
The corporation-binding provision is in original or amended articles delivered for filing with the Secretary of State. The Business Corporation Act supplies no separate governance-agreement certificate legend, certificate recall, uncertificated-share statement, purchaser-knowledge rule, or rescission clock (NMSA 1978 §§ 53-12-3, 53-13-4 to 53-13-5).
The ten-year number in Section 53-11-34(A) belongs to a voting trust. Subsection (B) expressly separates ordinary voting agreements from that voting-trust regime, while supplying specific enforceability for agreements about voting shares.
Liability remains ordinary unless another articles rule applies
Section 53-11-35(A) says who may exercise board powers under an articles provision, but it does not expressly relieve directors or shift director-law liability to those persons. Directors remain subject to the statutory conduct standard in Section 53-11-35(B).
The articles may contain the limited director monetary-liability provision in Section 53-12-2(E), subject to its conduct and role conditions. That is not a general shareholder personal-liability shield based on a governance agreement, and the Act states no public-market termination event for the articles route.
What trips people up
A written agreement signed by every shareholder does not by itself replace the board. The special enforceability sentence in Section 53-11-34(B) concerns how the parties vote their shares; a board-power allocation belongs in the articles.
Bylaws can regulate management but cannot conflict with the articles or law. They also do not become shareholder-controlled unless the articles reserve bylaw amendment power to shareholders.
The modern majority vote is not universal for every old corporation. A private corporation that existed on June 17, 1983, can retain the former two-thirds amendment threshold until it affirmatively opts into the lower rules.
Common questions
May the articles assign board powers to people who are not directors?
Yes. Section 53-11-35(A) says the articles may provide the extent to which board powers and duties are exercised or performed and identify the person or persons who do so.
Must every shareholder approve the original governance provision?
No special all-shareholder rule appears. One or more incorporators sign and deliver original articles; later amendments follow the board-proposal and shareholder-vote process, including any class or greater-vote requirement (NMSA 1978 §§ 53-12-1, 53-13-2, 53-18-6).
Does the ten-year limit apply to a voting agreement?
No. It applies to the voting trust described in Section 53-11-34(A). Subsection (B) says non-trust voting agreements are outside Subsection (A) and are valid and specifically enforceable.
