Corporate Bylaws Adoption and Amendment Requirements in Maine

At a glance

Requirements one by one

13-C M.R.S. § 101 names the Maine Business Corporation Act. 13-C M.R.S. § 102(4) defines the domestic corporation covered here as a for-profit or share corporation incorporated under or subject to the Act and not a foreign corporation.

Initial bylaws are mandatory, but organization may precede incorporation

13-C M.R.S. §§ 205 to 207 require the incorporators or board to adopt initial bylaws and permit any provision consistent with law and the articles. Section 205 expressly says the organizational meeting must occur before or after incorporation.

Named initial directors organize at a majority-called meeting. If the articles name no initial directors, the incorporators meet to elect directors and complete organization or elect a board to do so. Every incorporator may instead sign written consent describing the action.

For later board action, 13-C M.R.S. § 822 requires each director to sign and deliver a consent unless the governing documents require a meeting. The action occurs when all signed consents are delivered, although the consent may state an effective time and a director may revoke before all unrevoked consents arrive.

Board and shareholders share later power

Under 13-C M.R.S. §§ 1020 to 1021, shareholders may amend or repeal bylaws. The board may also act unless the articles or the higher-board-vote section reserves power to shareholders, or shareholders expressly protect a bylaw from board amendment, repeal, or reinstatement.

13-C M.R.S. § 826(5)(E) separately bars a committee from adopting, amending, or repealing bylaws.

Proxy and higher-board-vote bylaws preserve special powers

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

13-C M.R.S. § 1021 follows the actor of origin for a bylaw increasing the board's quorum or vote. A shareholder-originated version remains shareholder- controlled unless it says otherwise; a board-originated version may be changed by the board or shareholders. Board action must satisfy the current or proposed threshold, whichever is greater.

13-C M.R.S. § 207 separately permits temporary emergency bylaws unless the articles provide otherwise. Shareholders may amend or repeal them, and the emergency terms end with the emergency.

Current bylaws are directly inspectable at either listed office

13-C M.R.S. § 1601(5)(B) requires the corporation to keep its current bylaws or restated bylaws and all current amendments at its principal office or registered office. Under 13-C M.R.S. § 1602, a shareholder may inspect and copy them there 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 other second-tier records do not apply. The financial- information restrictions authorized by § 1602(2) do not turn ordinary bylaws into financial records or impose a proper-purpose test on their inspection.

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

A shareholder agreement defaults to an unlimited term

13-C M.R.S. § 743 permits a qualifying shareholder agreement to restrict or eliminate board authority, allocate voting power, or otherwise govern the corporation even when inconsistent with another Act 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 and an unlimited term unless it says otherwise. It ends when the corporation becomes a public corporation, and the board may then remove it and its references from the articles or bylaws without shareholder action.

What trips people up

Maine expressly permits the organizational meeting before incorporation. That does not eliminate the statute's actor, meeting-call, or unanimous incorporator- consent requirements.

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

Maine's shareholder agreement does not carry the ten-year default used by many older Model Act statutes. Its current default is an unlimited term unless the agreement states otherwise.

Common questions

Must a Maine corporation adopt bylaws?

Yes. 13-C M.R.S. § 206(1) directs the incorporators or board to adopt initial bylaws.

May the organizational meeting occur before incorporation?

Yes. Section 205(1) expressly permits the meeting before or after incorporation.

Can shareholders stop the board from changing a bylaw?

Generally yes under § 1020(2)(B), although the proxy-bylaw exception preserves limited board procedure-setting power.

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

No. Current bylaws are directly inspectable under § 1602(2) after five business days' signed written notice.
