Corporate Bylaws Adoption and Amendment Requirements in Mississippi

At a glance

Requirements one by one

Miss. Code § 79-4-1.01 names the Mississippi Business Corporation Act. The rules below address an ordinary domestic private corporation under that Act, not a nonprofit, professional, public, foreign, close, or regulated entity.

Initial bylaws are mandatory

Miss. Code § 79-4-2.06 requires the incorporators or board to adopt initial bylaws. The bylaws may regulate the corporation's management and affairs so long as they remain consistent with law and the articles.

Section 79-4-2.05 supplies the organization sequence. Named initial directors hold a meeting called by their majority to appoint officers, adopt bylaws, and complete organization. If the articles name no initial directors, a majority of the incorporators calls the meeting; the incorporators elect directors and complete organization or elect a board to complete it. The meeting may occur inside or outside Mississippi, and every incorporator may instead sign written consent.

The board has a separate action-without-meeting route under § 79-4-8.21. Every director must sign a consent describing the action and deliver it to the corporation. The action occurs when all signed consents have been delivered, unless the consent specifies an effective time, and a director may revoke before all unrevoked consents arrive. The Act states no post-filing deadline for initial adoption.

Board and shareholders share later power

Under Miss. Code § 79-4-10.20, shareholders may amend or repeal bylaws. The board may also amend or repeal them unless the articles or § 79-4-10.21 reserve power to shareholders, or shareholders expressly provide that the board may not amend, repeal, or reinstate a particular bylaw.

A board committee cannot exercise that authority. Section 79-4-8.25 expressly bars a committee from adopting, amending, or repealing bylaws.

Greater board quorum and vote bylaws have special protection

Miss. Code § 79-4-10.21 follows the actor of origin for a bylaw that increases a board quorum or voting requirement. A shareholder-adopted version is shareholder-controlled unless the bylaw says otherwise. A board-adopted version may be changed by the shareholders or board. Board action must meet the same quorum and vote required by the current or proposed rule, whichever is greater.

A shareholder-adopted higher-board-vote bylaw may itself prescribe a specified shareholder or board vote for later amendment or repeal. The former separate higher-shareholder-quorum or higher-shareholder-vote bylaw provision is not a current route: § 79-4-10.22 was repealed effective July 1, 2000.

Emergency, forum, and indemnification terms have narrow rules

Unless the articles provide otherwise, § 79-4-2.07 permits board-adopted emergency bylaws when a catastrophic event prevents a director quorum from being readily assembled. Shareholders may amend or repeal them; consistent regular bylaws continue during the emergency, and the emergency terms end when the emergency ends.

Section 79-4-2.02(b)(6) permits the articles to include or reference a bylaw requiring derivative proceedings and other listed internal claims to be brought in the appropriate court of the county where the principal office is located, subject to applicable law and jurisdiction. The statute frames this as an articles provision or articles reference, not a free-standing ordinary bylaw power.

Under § 79-4-8.58, bylaws may obligate the corporation in advance to provide statutory indemnification or expense advances. A later bylaw amendment cannot eliminate or impair the right for an earlier act or omission unless the original provision expressly authorized that later impairment.

Current bylaws are directly inspectable

Miss. Code § 79-4-16.01 requires the corporation to keep currently effective bylaws or restated bylaws and all current amendments at its principal office. The records may be electronic or otherwise convertible into paper form within a reasonable time.

Section 79-4-16.02 places those documents in the direct inspection tier. A shareholder may inspect and copy them during regular business hours at the principal office after giving at least five business days' signed written notice. The proper-purpose conditions for the section's second-tier records do not govern this direct tier, and the articles or bylaws cannot abolish or limit the right.

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

A unanimous shareholder agreement can override ordinary governance

Miss. Code § 79-4-7.32 permits a qualifying shareholder agreement to restrict or eliminate board authority, allocate voting power, or otherwise govern the corporation even when inconsistent with another provision of the chapter and not contrary to public policy. It may appear in the articles or bylaws with the approval of every current shareholder, or in a writing signed by every current shareholder and made known to the corporation.

The agreement defaults to ten years and unanimous amendment unless it says otherwise. It ends when the corporation becomes public. If it ends for any reason and is contained or referenced in the articles or bylaws, the board may delete it and its references without shareholder action.

What trips people up

Mississippi uses “shall” for initial adoption. Filing articles and electing a board do not replace the separate § 79-4-2.06 duty.

Section 79-4-10.22's location in the code does not create a current greater- shareholder-vote bylaw route. The section is repealed; the surviving special rule in § 79-4-10.21 concerns greater board quorum and voting requirements.

An internal-claims venue term under § 79-4-2.02(b)(6) depends on an articles provision or reference and remains subject to jurisdictional and other applicable law.

Common questions

Must a Mississippi corporation adopt bylaws?

Yes. Miss. Code § 79-4-2.06 requires the incorporators or board to adopt initial bylaws.

Can shareholders stop the board from changing a bylaw?

Yes. Under § 79-4-10.20, shareholders may expressly bar the board from amending, repealing, or reinstating a particular bylaw.

Can the board adopt bylaws without a meeting?

Yes, but every director must sign and deliver the consent required by § 79-4-8.21 before the board action occurs.

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

No. Current bylaws are in § 79-4-16.02's direct inspection tier. At least five business days' signed written notice is required.
