    (1)   Upon the application of the guardian; or
    (2)   Upon the notice to the guardian.
  (c)   Upon the death or incompetence of a party, the court may extend the time within which a petition to confirm, vacate, or modify the award, or to stay arbitration, must be made.
  (d)   If a party dies after an award was delivered, the subsequent proceedings are the same as where a party dies after a verdict.
