California Code, Government Code - GOV § 27297.7

(a) Following adoption of an authorizing resolution by the board of supervisors, the county recorder may, within 30 days of recordation of a deed, quitclaim deed, or deed of trust, notify by mail the party or parties executing the document. The recorder may require, as a condition of recording, that a deed, quitclaim deed, or deed of trust indicate the assessor's identification number or numbers that fully contain all, or a portion of, the real property described in the legal description. If the description contains more than one assessor' s parcel, all assessor's parcels shall be indicated. The form of the entry shall be substantially as follows:

Assessor's Identification Number ___-___-___.

(b) This section shall not apply to the recordation of any document where the federal government, or state, county, city, or any subdivision of the state acquires title.

(c) The failure of the county recorder to provide the notice as permitted by this section shall not result in any liability against the recorder or the county. In the event that the notice is returned to the recorder by the postal service as undeliverable, the recorder is not required to retain the returned notice.

(d) Where the county recorder contracts with any party or parties for the performance of the processing or the mailing of the notice, or both, as authorized by this section, the contract shall be awarded by competitive bid. The county recorder shall solicit written bids for the contract in a newspaper of general circulation in the county, and all bids received shall be publicly opened and the contract awarded to the lowest responsible bidder. If the county recorder or his or her designee deems the acceptance of the lowest responsible bid is not in the best interest of the county, all bids may be rejected.
