Cal. Probate Code § 9964

(a) The court shall make an order authorizing the personal representative to grant the option upon the terms and conditions stated in the order if the court is satisfied as to all of the following: (1) Good reason exists to grant the option and granting the option will be to the advantage of the estate. (2) It does not appear that a higher offer with respect to the purchase price of the real property subject to the option may be obtained. An offer is a higher offer with respect to purchase price only if the offer satisfies the requirements of Section 10311 governing increased bids in real property sales. (3) It does not appear that a better offer with respect to the terms of the option may be obtained. An offer is a better offer with respect to the terms of the option only if the offer is materially more advantageous to the estate. (b) A higher offer made either for cash or on credit, whether on the same or different credit terms, or a better offer, shall be considered only if the personal representative informs the court in person or by counsel, before the court makes its order authorizing the granting of the option, that the offer is acceptable.
