Wash. Rev. Code § 64.12.050
When any two or more persons are opposing claimants under the laws of the United States to any land in this state, and one is threatening to commit upon such land waste which tends materially to lessen the value of the inheritance and which cannot be compensated by damages and there is imminent danger that unless restrained such waste will be committed, the party, on filing his or her complaint and satisfying the court or judge of the existence of the facts, may have an injunction to restrain the adverse party. In all cases he or she shall give notice and bond as is provided in other cases where injunction is granted, and the injunction when granted shall be set aside or modified as is provided generally for injunction and restraining orders.
