(A) Pleading. In an action brought by one or more shareholders in an incorporated or unincorporated association because the association has refused or failed to enforce rights which may properly be asserted by it, the complaint shall set forth under oath and with particularity the efforts of the plaintiff to secure from the managing directors or trustees the action the plaintiff desires and the reasons for the failure to obtain such action, or the reasons for not making such an effort.
(B) Security. At any stage of an action under this subrule the court may require such security and impose such terms as shall fairly and adequately protect the interests of the class or association in whose behalf the action is brought or defended.
(C) Notice. The court may order that notice be given, in the manner and to the persons it directs,
(1) of the right of absent persons to appear and present claims and defenses;
(2) of the pendency of the action;
(3) of a proposed settlement;
(4) of entry of judgment; or
(5) of any other proceedings in the action.
(D) Inadequate Representation. Whenever the representation appears to the court inadequate to protect the interests of absent persons who may be bound by the judgment, the court may at any time prior to judgment order an amendment of the pleadings to eliminate references to representation of absent persons, and the court shall enter judgment in such form as to affect only the parties to the action and those adequately represented.

Plain-English Summary

MCR 3.502 covers the shareholder suit brought because the association will not sue for itself. The rule speaks to an action brought by one or more shareholders in an incorporated or unincorporated association that has refused or failed to enforce rights the association could properly assert. It addresses four things: the pleading, the security, the notice, and the fallback when the representation turns out to be thin.

The sworn complaint

Subrule (A) puts a verification requirement at the front of the case. The complaint must set forth under oath and with particularity the efforts the plaintiff made to secure from the managing directors or trustees the action the plaintiff wants, and the reasons those efforts did not produce it. A plaintiff who made no such effort must instead plead, to the same standard, the reasons for not making one.

Two phrases carry the weight. Under oath means the allegations are sworn rather than merely pleaded. With particularity means the subrule asks for specifics either way — what was asked of the directors or trustees and what came back, or why nothing was asked at all.

Security

Subrule (B) lets the court act at any stage of the action. It may require such security and impose such terms as will adequately protect the interests of the class or association on whose behalf the action is brought or defended. The security runs to the interests of the class or association rather than to the party who posts it, and the subrule covers an action brought or defended on their behalf.

Notice

Subrule (C) leaves notice to the court, both in manner and in audience. The court may order notice given to the persons it directs of any of the following:

  • the right of absent persons to appear and present claims and defenses;
  • the pendency of the action;
  • a proposed settlement;
  • entry of judgment; or
  • any other proceedings in the action.

The subrule is written as a grant of authority, not a checklist of required mailings. Nothing in it makes any of these notices automatic.

When representation falls short

Subrule (D) is the release valve for absent persons. Whenever the representation appears to the court inadequate to protect the interests of absent persons who may be bound by the judgment, the court may order an amendment of the pleadings that eliminates references to representation of absent persons. It may do so at any time prior to judgment.

The judgment that follows is then entered in a form that affects only the parties to the action and those adequately represented. The case does not end when representation fails. It narrows to the people who are before the court, and the judgment is entered in a form that does not reach the absent persons.

Frequently Asked Questions

What must a shareholder plead before suing on behalf of a corporation in Michigan?

Subrule (A) requires the complaint to set forth under oath and with particularity the plaintiff's efforts to secure from the managing directors or trustees the action the plaintiff desires, together with the reasons for the failure to obtain that action.

A plaintiff who made no such effort must instead set forth the reasons for not making one, under the same oath and particularity requirement.

Does MCR 3.502 apply to unincorporated associations?

Yes. Subrule (A) describes an action brought by one or more shareholders in an incorporated or unincorporated association. The rule turns on the association having refused or failed to enforce rights which may properly be asserted by it, not on its corporate form.

Can a Michigan court require security in a shareholder secondary action?

Subrule (B) allows it at any stage of the action. The court may require such security and impose such terms as will adequately protect the interests of the class or association in whose behalf the action is brought or defended.

The subrule sets no amount, no trigger, and no timing. It leaves both the security and the accompanying terms to the court.

What notice do absent shareholders receive in a secondary action?

Under subrule (C), the court may order notice given in the manner and to the persons it directs. The listed occasions are the right of absent persons to appear and present claims and defenses, the pendency of the action, a proposed settlement, entry of judgment, and any other proceedings in the action.

The subrule is permissive. It grants the court authority to order these notices rather than requiring them in every case.

What happens if the shareholder is not an adequate representative?

Subrule (D) applies whenever the representation appears to the court inadequate to protect the interests of absent persons who may be bound by the judgment. At any time prior to judgment, the court may order an amendment of the pleadings to eliminate references to representation of absent persons.

The court then enters judgment in a form that affects only the parties to the action and those adequately represented.
