When a person is held as trustee upon a negotiable paper in an action in which a claimant does not appear or is not cited in, and an action is afterwards brought against the trustee upon such paper by an assignee thereof, the trustee may plead the former judgment against himself or herself in bar. The court shall thereupon issue a citation, and such assignee shall cause it to be served on the plaintiff in the trustee process or his or her attorney of record.
