Cal. Pub. Util. Code § 1412
Within 20 days after the commission has made and filed its finding, the owner of the lands, property, and rights may file with the legislative or other governing body of the political subdivision a written stipulation consenting and agreeing to accept the just compensation fixed by the commission. Upon the filing of the stipulation, the political subdivision shall proceed with all due diligence to provide the necessary funds under the law governing the providing of such funds, for paying the just compensation fixed by the commission. Whenever the just compensation has been tendered by the political subdivision, a deed of grant, bargain, and sale conveying the owner's right, title, and interest in and to the lands, property, and rights to the political subdivision shall be executed and delivered by the owner, and the other claimants who have any right, title, or interest in the property shall execute appropriate instruments conveying or releasing to the political subdivision their respective rights, titles, and interests therein. If the deed or the instruments of convenience or release are not executed and delivered within 60 days after such tender has been made, the political subdivision may commence an action in a court of competent jurisdiction or proceed under Section 1413.
