Cal. Rev. & Tax. Code § 55336

(a) At least 30 days prior to the filing or recording of liens under Chapter 14 (commencing with Section 7150) or Chapter 14.5 (commencing with Section 7220) of Division 7 of Title 1 of the Government Code, the board shall mail to the taxpayer a preliminary notice. The notice shall specify the statutory authority of the board for filing or recording the lien, indicate the earliest date on which the lien may be filed or recorded, and state the remedies available to the taxpayer to prevent the filing or recording of the lien. In the event tax liens are filed for the same liability in multiple counties, only one preliminary notice shall be sent.

(c) If the board determines that filing a lien was in error, it shall mail a release to the taxpayer and the entity recording the lien as soon as possible, but not later than seven days, after this determination and receipt of lien recording information. The release shall contain a statement that the lien was filed in error. In the event the erroneous lien is obstructing a lawful transaction, the board shall immediately issue a release of lien to the taxpayer and the entity recording the lien.

(d) When the board releases a lien erroneously filed, notice of that fact shall be mailed to the taxpayer and, upon the request of the taxpayer, a copy of the release shall be mailed to the major credit reporting companies in the county where the lien was filed.

(e) The board may release or subordinate a lien if the board determines that the release or subordination will facilitate the collection of the tax liability or will be in the best interest of the state and the taxpayer.
