Wollenberg v. Tonningsen

Holding

The court held that a complaint for declaratory relief need not be predicated solely upon a disputed written instrument to state a justiciable controversy, as the statutory scheme equally permits such an action where a party seeks a declaration of rights or duties with respect to property or another person, and that the trial court's findings on the validity of a trust and the propriety of appointing a substituted trustee were fully supported by the evidence and established legal principles.
