§ 11. Proceedings in case of death of assignee. In case an assignee shall die during the pendency of any proceeding under this article, or at any time subsequent to the filing of any bond required herein, his personal representative or successor in office, or both, may be brought in and substituted in such proceeding on such notice, of not less than eight days, as the judge may direct to be given; and any decree made thereafter shall bind the parties thus substituted as well as the property of such deceased assignee, provided, however, that if such assignee dies subsequent to the filing of his bond and before any proceedings may have been had thereunder, then the surety on such bond may apply to the judge for an accounting, who may, on such terms as to him seem just and proper, appoint another assignee and release such surety.
