Wash. Super. Ct. Civ. R. 25

(a) Death.

(1) Procedure. If a party dies and the claim is not thereby extinguished, the court may

order substitution of the proper parties. The motion for substitution may be made by the

successors or representatives of the deceased party or by any party and, together with the notice

of hearing, shall be served on the parties as provided by rule 5 for service of notices, and upon

persons not parties in the manner provided by statute or by rule for the service of a summons. If

substitution is not made within the time authorized by law, the action may be dismissed as to the

deceased party.

(2) Partial Abatement. In the event of the death of one or more of the plaintiffs or of one or

more of the defendants in an action in which the right sought to be enforced survives only to the

surviving plaintiffs or only against the surviving defendants, the action does not abate. The death

shall be suggested upon the record and the action shall proceed in favor of or against the

surviving parties.

(b) Incompetency. If a party becomes incompetent, the court upon motion served as

provided in section (a) of this rule may allow the action to be continued by or against the party’s

representative.

(c) Transfer of Interest. In case of any transfer of interest, the action may be continued by

or against the original party unless the court upon motion directs the person to whom the interest

is transferred to be substituted in the action or joined with the original party. Service of the

motion shall be made as provided in section (a) of this rule.

(d) Public Offices; Death or Separation From Office. [Reserved.]
