Wash. Super. Ct. Civ. R. 23.1

In a derivative action brought by one or more shareholders or members to enforce a right of

a corporation or of an unincorporated association, the corporation or association having failed to

enforce a right which may properly be asserted by it, the complaint shall be verified and shall

allege (a) that the plaintiff was a shareholder or member at the time of the transaction of which

the plaintiff complains or that the plaintiff’s share or membership thereafter devolved on the

plaintiff by operation of law, and (b) that the action is not a collusive one to confer jurisdiction

on a court of this state which it would not otherwise have. The complaint shall also allege with

particularity the efforts, if any, made by the plaintiff to obtain the action the plaintiff desires from

the directors or comparable authority and, if necessary, from the shareholders or members, and

the reasons for the plaintiff’s failure to obtain the action or for not making the effort. The

derivative action may not be maintained if it appears that the plaintiff does not fairly and

adequately represent the interests of the shareholders or members similarly situated in enforcing

the right of the corporation or association. The action shall not be dismissed or compromised

without the approval of the court, and notice of the proposed dismissal or compromise shall be

given to shareholders or members in such manner as the court directs.
