The California Judicial Council has developed forms for use in all California state courts. Mandatory forms are marked with "Form Adopted for Mandatory Use" in their lower left hand corner. Other forms are optional but will save you time and ensure you are using a form that complies with court rules.
Most local California state courts have also added their own supplementary forms for use within the local court.
Multiple websites and databases provide access to these forms:
The California court system and its individual districts provide free, online sample pleadings and motions, as well as guidance on drafting and filing them.
Note that LA is in the second district.
The federal court system provides free online access to its forms and some sample filings. Most local federal courts also provide their own supplementary forms.
