(2) A provision that the conservator has the right to avoid any transaction made by the conservatee pursuant to the authority of the order if the transaction is not one into which a reasonably prudent person might enter. (c) The court, in its discretion, may provide in the order that, unless extended by subsequent order of the court, the order or specific provisions of the order terminate at a time specified in the order. (d) An order under this section continues in effect until the earliest of the following times: (1) The time specified in the order, if any. (2) The time the order is modified or revoked. (3) The time the conservatorship of the estate is terminated. (e) An order under this section may be modified or revoked upon petition filed by the conservator, conservatee, the spouse or domestic partner of the conservatee, or any relative or friend of the conservatee, or any interested person. Notice of the hearing on the petition shall be given for the period and in the manner provided in Chapter 3 (commencing with Section 1460) of Part 1.
