Cal. Gov. Code § 53812
A trustee, appointed pursuant to Section 53811, or acting under a deed of trust, indenture, or other agreement, whether or not all certificates have been declared due and payable, may have a receiver appointed. The receiver may, to the same extent that the board itself could do, enter and take possession of the public buildings of the board, or any parts thereof, the revenues, rentals, or receipts from which are applicable to the payment of the certificates in default, and operate and maintain the public buildings and collect and receive all rentals and revenues thereof arising therefrom in the same manner as the board might do. The receiver shall deposit money in a separate account and apply it in such manner as the court directs. In any action or proceeding by the trustees, the fees, counsel fees, and expenses of the trustees, and of the receiver, and all costs and disbursements allowed by the court, are a first charge on any revenues and receipts derived from the public buildings of the board, the revenues or receipts from which are or may be applicable to the payment of the certificates in default. The trustee shall have and possess all the powers necessary or appropriate for the exercise of any functions specifically set forth in this article or incident to the general representation of the certificate holders in the protection and enforcement of their rights; provided, however, that nothing in this section or any other section in this article shall authorize any trustee appointed pursuant to Section 53811, for the purpose of operating and maintaining any public buildings of the board, to sell, assign, mortgage, or otherwise dispose of, any of the assets of whatever kind and character belonging to the board.
