Cal. Rev. & Tax. Code § 19263

At any sale authorized by Section 19262, the property shall be sold by the Franchise Tax Board or its duly authorized agent in accordance with law and the notice of sale, and the Franchise Tax Board shall deliver to the purchaser a bill of sale for the property so sold and the bill of sale shall vest title in the purchaser. The unsold portion of any property so seized may be left at the place of sale at the risk of the taxpayer. If, upon any sale, the moneys so received exceed the amount of all taxes, interest, penalties and costs due the state from the taxpayer, any excess shall be returned to the taxpayer and a receipt therefor obtained. However, if any person having an interest in or lien upon the property has filed with the Franchise Tax Board prior to any sale notice of the interest or lien, the Franchise Tax Board shall withhold any excess pending a determination of the rights of the respective parties thereto by a court of competent jurisdiction.

If, for any reason, the receipt of the taxpayer is not available, the Franchise Tax Board shall deposit the excess moneys with the Treasurer, as trustee for the owner, subject to the order of the taxpayer or his or her trust or estate, or in the case of a corporation, its successor through reorganization, merger, or consolidation, or its stockholders upon dissolution.
