Legal Question in Consumer Law in California

See Code of Civil Procedure section 430.10. You can find examples of a demurrer at a law library. There might be some in form books. But it also involves knowledge of which precedential cases and statutes apply to your particular situation.

Remember that the purpose of a complaint is to provide sufficient facts to put you on notice of what the plaintiff is claiming. The plaintiff is not required to provide every fact, only enough to state a cause of action to proceed with the lawsuit. Other facts might be developed later through "discovery," i.e. written interrogatories, document demands, requests for admissions, subpoenas, and depositions.
