Nonprofit Corporation Articles Amendment Approval and Filing in Iowa

At a glance

Requirements one by one

Choose the approval route

Under § 504.1001, a corporation may add or change a permitted articles provision or delete one not required. § 504.1003(1)(a) calls for board approval in a public benefit or religious corporation when the amendment does not concern the number or composition of directors, their terms, or how they are selected. The board or members may seek member approval under § 504.1003(4), and either may condition adoption under § 504.1003(2)-(3).

The ordinary member threshold in § 504.1003(1)(b) is the lesser of two-thirds of votes cast or a majority of voting power that could be cast. The Act, articles, bylaws, board, or members may require more under § 504.1003(1)-(3). § 504.713(1) sets a general 10% of entitled votes meeting quorum unless law or governing documents set a different one.

Check class and other approval rights

Under § 504.1004(1)-(2), a class of a public benefit corporation votes separately for a different effect on its voting rights; a mutual benefit class has broader triggers, including changes to membership counts and transfer or dissolution rights. A religious corporation has a class vote only when its articles or bylaws provide one (§ 504.1004(3)). A required class vote uses the lesser of two-thirds of class votes cast or a majority of class voting power unless the religious corporation's documents provide otherwise (§ 504.1004(5)). § 504.1031 allows the articles to require a named person's written approval and protects that term from amendment without the same approval.

Without members and for narrow board changes

If there are no members, § 504.1002(2) allows incorporators to amend until directors are chosen, and then requires a majority of directors in office. Board meeting notice must describe the proposal; § 504.823(3) gives directors at least seven days' written notice of this member-equivalent action unless waived. § 504.1002(1) also permits specified board-only changes, such as deleting initial director information or making limited name changes, unless the articles provide otherwise.

Give notice, file, and set the date

For a member meeting, § 504.1003(4) requires written notice with a copy or summary of the amendment; § 504.705(3) sets the fair-notice timing, ordinarily 10 to 60 days and at least 30 days for mail other than first class or registered mail. § 504.1003(5) requires a copy or summary in written-consent or ballot solicitation. § 504.704(1) requires written consents from members holding at least 80% of voting power unless the articles or bylaws limit or prohibit consent. § 504.708 permits a written ballot with meeting-equivalent quorum and vote counts unless limited by the governing documents.

§ 504.1005 requires articles of amendment stating the corporate name, adopted text and date, the applicable approval certification, and any outside-person approval. Under § 504.111(6)-(9), the presiding board officer, president, other officer, or applicable incorporator signs and delivers the document to the Secretary of State. The Secretary of State's nonprofit fee table lists $10 for articles of amendment. § 504.114 makes filing the default effective event and permits a later specified time or date within 90 days. Under § 504.1006(2), new amendments in a restatement use the ordinary approval process.

What trips people up

For a public or mutual benefit corporation amendment that terminates all members or a class, or redeems or cancels memberships, § 504.1032 adds special safeguards. It requires a two-thirds vote of each class and, for a mutual benefit corporation, board notice of the amendment's general nature before a proposing resolution. A timely opposition statement may also need to accompany the member notice under § 504.1032(3).

Common questions

Does a member-consent approval take effect immediately?

If some members did not sign, § 504.704(4) requires notice to them and makes member approval effective 10 days after that notice.

Must the filing be notarized?

§ 504.111(7) requires the signer's name and capacity but makes an acknowledgment or verification optional.
