California Code, Civil Code - CIV § 8214

(a) Each person who has served a preliminary notice may file the preliminary notice with the county recorder. A preliminary notice filed pursuant to this section shall comply with the requirements of Section 8102.

(b) Upon the acceptance for recording of a notice of completion or notice of cessation the county recorder shall mail to those persons who have filed a preliminary notice, notification that a notice of completion or notice of cessation has been recorded on the property, and shall affix the date that the notice of completion or notice of cessation was recorded with the county recorder. The notification given by the county recorder under this section is not governed by the requirements of Chapter 2 (commencing with Section 8100) of Title 1.

(c) The failure of the county recorder to mail the notification to the person who filed a preliminary notice, or the failure of those persons to receive the notification or to receive complete notification, shall not affect the period within which a claim of lien is required to be recorded. However, the county recorder shall make a good faith effort to mail notification to those persons who have filed the preliminary notice under this section and to do so within five days after the recording of a notice of completion or notice of cessation.

(d) The county recorder may cause to be destroyed all documents filed pursuant to this section, two years after the date of filing.

(e) The preliminary notice that a person may file pursuant to this section is for the limited purpose of facilitating the mailing of notice by the county recorder of recorded notices of completion and notices of cessation. The notice that is filed is not a recordable document and shall not be entered into those official records of the county which by law impart constructive notice. Notwithstanding any other provision of law, the index maintained by the recorder of filed preliminary notices shall be separate and distinct from those indexes maintained by the county recorder of those official records of the county which by law impart constructive notice. The filing of a preliminary notice with the county recorder does not give rise to any actual or constructive notice with respect to any party of the existence or contents of a filed preliminary notice nor to any duty of inquiry on the part of any party as to the existence or contents of that notice.
