California Civil Code Section 3144

(a) No lien provided for in this chapter binds any property for a longer period of time than 90 days after the recording of the claim of lien, unless within that time an action to foreclose the lien is commenced in a proper court, except that, if credit is given and notice of the fact and terms of such credit is recorded in the office of the county recorder subsequent to the recording of such claim of lien and prior to the expiration of such 90-day period, then such lien continues in force until 90 days after the expiration of such credit, but in no case longer than one year from the time of completion of the work of improvement.

   (b) If the claimant fails to commence an action to foreclose the lien within the time limitation provided in this section, the lien automatically shall be null and void and of no further force and effect.
