Nonprofit Corporation Membership Exit and Termination in Iowa

At a glance

Requirements one by one

Classes, transfer, and resignation

An Iowa nonprofit need not have members (§ 504.603). If it does, § 504.611 gives members equal rights and obligations on voting, dissolution, redemption, and transfer unless articles or bylaws establish different classes. Mutual benefit members may transfer only if documents allow it, while public benefit and religious members cannot transfer a membership or any right arising from it (§ 504.612(1)–(2)). A later restriction on an existing permitted transfer also needs approval by the members and affected member (§ 504.612(3)).

Under § 504.621(1), a member may resign at any time. Subsection (2) preserves obligations incurred or commitments made before resignation.

Involuntary exit

For public or mutual benefit corporations, § 504.622(1) first points to the reasons and manner stated in the articles or bylaws. Where the documents do not address termination or suspension, subsection (2) requires a fair, reasonable, good-faith procedure. A document-based route gives at least 15 days' written reasons notice and a chance to respond orally or in writing at least five days before effectiveness to someone able to stop the action. The alternative considers all relevant circumstances before an authorized decision maker (§ 504.622(3)). Mailed notice under the section uses first-class or certified mail to the last recorded member address (§ 504.622(4)).

What trips people up

The 15-day and five-day route in § 504.622(3) is not automatically imposed when articles or bylaws already address termination or suspension; § 504.622(1)–(2) puts those documents first. A challenge, including one alleging defective notice, still must begin within one year after the effective date (§ 504.622(5)).

Section 504.614 permits a member to become liable for dues, assessments, or fees, but an article, bylaw, or board resolution merely imposing them does not itself create payment liability. Prior obligations may remain after resignation under § 504.621(2) or after expulsion or suspension under § 504.622(6). The corporation also keeps an internal member record from which a class-by-class voting list can be prepared (§ 504.1601(3)).

Common questions

May a mutual benefit corporation later restrict an existing transfer right? Section 504.612(3) requires approval by both the members and the affected member for a restriction to bind a membership issued before that restriction.

Does resignation settle dues already owed? Section 504.621(2) keeps earlier obligations and commitments in place; § 504.614 requires more than an authorizing document or resolution alone to create liability.
