Corporate Bylaws Adoption and Amendment Requirements in Montana

At a glance

Requirements one by one

Mont. Code Ann. § 35-14-101 names the Montana Business Corporation Act. Mont. Code Ann. § 35-14-140(5) identifies the domestic for-profit corporation covered here, while the same section classifies corporate bylaws as private organic rules and the articles as the public organic record.

Initial bylaws are mandatory after incorporation

Mont. Code Ann. §§ 35-14-205 to 35-14-206 require the incorporators or board to adopt initial bylaws and permit any provision consistent with law and the articles. Named initial directors organize at a meeting called by a majority. If the articles name no initial directors, a majority of the incorporators calls a meeting to elect directors and complete organization or to elect a board that completes organization. The meeting may occur inside or outside Montana, but the section places it after incorporation and states no later deadline.

Every incorporator may instead sign written consent describing the action. For board action, Mont. Code Ann. § 35-14-821 requires every director to sign and deliver a consent unless the articles or bylaws require a meeting. The board acts when all signed consents are delivered, although the consent may state a later effective time.

Board and shareholders share later power

Under Mont. Code Ann. §§ 35-14-1020 to 35-14-1022, shareholders may amend or repeal bylaws. The board may also act unless the articles or a special-bylaw section reserves power to shareholders, or shareholders expressly protect a bylaw from board amendment, repeal, or adoption.

Mont. Code Ann. § 35-14-825(4)(d) separately bars a board committee from adopting, amending, or repealing bylaws.

Meeting-place and higher-board-vote bylaws follow special safeguards

Mont. Code Ann. § 35-14-1021 applies its actor-of-origin rule both to a bylaw that raises the board's quorum or vote and to a bylaw requiring shareholder meetings at a place. A shareholder-originated version remains shareholder- controlled unless it says otherwise; a board-originated version may be changed by the board or shareholders.

A shareholder-adopted higher-board-threshold bylaw may specify the shareholder or board vote needed for amendment or repeal. When the board changes such a bylaw, its action must satisfy the current or proposed quorum and vote, whichever is greater.

Proxy, election, emergency, and forum bylaws retain separate limits

Section 35-14-206 permits proxy-access and qualifying proxy-expense bylaws. Even if shareholders protect one, subsection (4) preserves the board's power over conditions and procedures needed for a reasonable, practical, and orderly process.

Mont. Code Ann. § 35-14-1022 permits an election bylaw unless the articles specifically prohibit it, alter the referenced ordinary vote, or provide cumulative voting. The bylaw supplies an uncontested-election framework and a limited term for an elected nominee who receives more votes against than for; repeal power follows the actor of origin. The current section is not limited to a statutory public corporation.

Mont. Code Ann. § 35-14-207 permits temporary emergency bylaws unless the articles provide otherwise. Shareholders may amend or repeal them, and the emergency terms end with the emergency. Mont. Code Ann. § 35-14-208 also permits an internal-claim forum bylaw, but it cannot bar suit in Montana courts or require arbitration.

Current bylaws are directly inspectable

Mont. Code Ann. §§ 35-14-1601 to 35-14-1602 require the corporation to maintain its current bylaws in a manner that makes them available within a reasonable time. A shareholder may inspect and copy them at the principal office during regular business hours after at least five business days' signed written notice. Current bylaws are in the direct tier, so the proper- purpose conditions for accounting and specified board records do not apply, and the articles or bylaws cannot abolish or limit the inspection right.

The surveyed Act states no general signature, certification, acknowledgment, notarization, or Secretary of State filing requirement for ordinary bylaws.

A shareholder agreement states its own duration limits

Mont. Code Ann. § 35-14-732 permits a qualifying shareholder agreement to restrict or eliminate board authority, allocate voting power, or otherwise govern the corporation even when inconsistent with another chapter provision and not contrary to public policy. It may appear in the articles or bylaws with every current shareholder's approval, or in a writing signed by every current shareholder and made known to the corporation.

The agreement defaults to unanimous amendment unless it says otherwise, and any duration limits must appear in the agreement. The current section states no separate public-company cutoff. If the agreement ends, the board may remove it and its references from the articles or bylaws without shareholder action.

What trips people up

Montana protects more than a higher-board-vote bylaw under the actor-of-origin rule. Section 35-14-1021 also protects a bylaw requiring shareholder meetings to be held at a place.

Protecting a proxy-access or proxy-expense bylaw does not eliminate all board authority. Section 35-14-206(4) preserves the board's reasonable process- setting power.

The election-bylaw route in § 35-14-1022 is not written as a public-company- only provision, while the shareholder-agreement section does not state the public-company cutoff found in some states' statutes.

Common questions

Must a Montana corporation adopt bylaws?

Yes. Mont. Code Ann. § 35-14-206(1) directs the incorporators or board to adopt initial bylaws.

Can shareholders stop the board from changing a bylaw?

Generally yes under § 35-14-1020(2)(b), although special rules preserve board authority over proxy-bylaw procedures and identify who may change higher-vote, meeting-place, and election bylaws.

Can the board adopt bylaws without a meeting?

Yes, unless the articles or bylaws require a meeting, but every director must sign and deliver the consent required by § 35-14-821.

Does a shareholder need a proper purpose to inspect current bylaws?

No. Current bylaws are directly inspectable under § 35-14-1602(1) after five business days' signed written notice.
