I'm not entirely sure if I understand the question. But, if you are looking for a California mechanics lien template, you can download one here.
However, if you are looking for a mechanics lien that has already been recorded against a property, you will need to check the county recorder's office in the county where the property is located. A full list of CA county recorder's offices and their contact information can be found here. Depending on the county, they may or may not offer online access to their records.
