Executor
(d) Executor defined. For purposes of chapter 13, the executor is the executor or administrator of the decedent's estate. However, if no executor or administrator is appointed, qualified or acting within the United States, the executor is the fiduciary who is primarily responsible for payment of the decedent's debts and expenses. If there is no such executor, administrator or fiduciary, the executor is the person in actual or constructive possession of the largest portion of the value of the decedent's gross estate.
