Cal. CCP § 699.060

(a) The levying officer shall release property levied upon when the levying officer receives a written direction to release the property from the judgment creditor’s attorney of record or, if the judgment creditor does not have an attorney of record, from the judgment creditor, or when the levying officer receives a certified copy of a court order for release, or when otherwise required to release the property. The release shall include the signature and name of the attorney or judgment creditor issuing the release. The release extinguishes any execution lien or attachment lien in favor of the judgment creditor on the property released.

(b) If the property to be released has been taken into custody under the levy, it shall be released to the person from whom it was taken unless otherwise ordered by the court. If the person does not claim the property to be released, the levying officer shall retain custody of the property and shall serve on the person a notice of where possession of the property may be obtained. Service shall be made personally or by mail. If the person does not claim the property within 30 days after the notice is served, the levying officer shall sell the property in the manner provided by Article 6 (commencing with Section 701.510), other than cash, which does not have a value exceeding its face value. The levying officer shall deposit the proceeds of sale and cash, after first deducting the levying officer’s costs, with the county treasurer of the county where the property is located, payable to the order of the person. If the amount deposited is not claimed by the person, or the legal representative of the person, within five years after the deposit is made by making application to the treasurer or other official designated by the county, it shall be paid into the general fund of the county.

(c) If the property to be released has not been taken into custody under the levy, the levying officer shall release the property by issuing a written notice of release and serving it on the person who was served with a copy of the writ and a notice of levy to create the lien. Service shall be made personally or by mail.

(d) If the property to be released was levied upon by recording or filing a copy of the writ and a notice of levy, the levying officer shall record or file a written notice of release in the same office.

(e) The levying officer is not liable for releasing property in accordance with this section nor is any other person liable for acting in conformity with the release.

(f) The written direction to release property specified in subdivision (a) may be transmitted electronically to the levying officer pursuant to Chapter 2 (commencing with Section 263) of Title 4 of Part 1.
