Nonprofit Corporation Bylaw Adoption and Amendment Requirements in Michigan

At a glance

Requirements one by one

Initial adoption and content

Under § 450.2231(1)(a), incorporators, shareholders, members, or the board must adopt initial bylaws unless the articles reserve the power exclusively to one of those groups. Section § 450.2223 lets a majority of incorporators select the board before or after filing the articles and adopt bylaws at a meeting or by written instrument. After filing, any director may call the first board meeting on at least three days' mailed notice to each director; a majority forms the first-meeting quorum. Section § 450.2231(2) permits bylaw provisions for corporate affairs only if consistent with law and the articles.

Later amendments and voting

Section § 450.2231(1)(b) gives shareholders, members, and the board amendment and repeal power unless the articles reserve it exclusively. A member or shareholder who adopts a bylaw may state in that bylaw that the board cannot amend or repeal it under § 450.2231(1)(c). For a board amendment, § 450.2523(2) requires a vote of at least a majority of directors then in office, unless the articles or bylaws require more. That differs from the ordinary board action rule in § 450.2523(1), which measures a majority of directors present at a meeting with quorum.

For member or shareholder action, § 450.2441(2) ordinarily requires a majority of votes cast, subject to a higher articles vote or another statutory rule. Section § 450.2442 permits a separate class vote under the articles or bylaws and sets its default at a majority of votes cast by the class. Section § 450.2455 makes a higher voting proportion in the articles control over the Act's ordinary threshold.

Notice and emergency power

Section § 450.2404(1) generally calls for written notice of member or shareholder meeting purposes 10 to 60 days before the meeting. Board meeting notice follows the bylaws under § 450.2521(2). The corporation's powers include adopting, amending, or repealing emergency bylaws under § 450.2261(1)(d); the ordinary bylaw actor rule and any exclusive articles reservation in § 450.2231 still require attention.

Records and access

Section § 450.2485 requires books and records of account and minutes of shareholder or member, board, and executive committee proceedings. For a corporation organized on a membership basis, § 450.2487(2) permits a member of record to inspect other books and records during regular business hours for a proper purpose, after a written demand identifying the purpose and records with reasonable particularity. Section § 450.2487(7) allows specified inspection limits when approved on a good-faith finding about privacy, association, corporate purposes, or donor interests. Read those restrictions before treating a demand as automatic access to a particular record.

What trips people up

A board majority present can approve ordinary board business under § 450.2523(1), but a bylaw amendment needs a majority of the board then in office under subsection (2). A member-adopted bylaw can also bar board amendment under § 450.2231(1)(c). Those two checks should be made separately.

Common questions

Can incorporators adopt bylaws before filing? Section 450.2223 permits a majority of incorporators to adopt bylaws before or after the articles are filed.

Can a member amendment be approved by a bare majority? Under § 450.2441(2), the general rule is a majority of votes cast. The articles, another statutory rule, or a class vote under § 450.2442 can change the result.

Does a membership-corporation member automatically see every corporate record? Section 450.2487(2) requires a proper-purpose, particularized written demand for books and records; subsection (7) permits the specified inspection restrictions.
