If the trustee of a trust that is not revocable has refused to transfer administration of the trust to a successor trust company on request of the beneficiaries described in subdivision (c) of Section 15640 and the court in subsequent proceedings under Section 17200 makes an order removing the existing trustee and appointing a trust company as successor trustee, the court may, in its discretion, award costs and reasonable attorney’s fees incurred by the petitioner in the proceeding to be paid by the trustee or from the trust as ordered by the court.
