(a) Notwithstanding the death of a party who made a written agreement to submit a controversy to arbitration, the arbitration proceedings may begin or continue if an application has been filed by or notice given to his personal representative.

(b) If a guardian has been appointed, the proceedings may be continued:

(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.
