Legal Question in Credit and Debt Law in California

You first must file a proper response to the complaint within 30 days of service of the summons and complaint, i.e. an answer, demurrer, and/or motion to strike. Once you do that, you are entitled to conduct "discovery," which means sending to the plaintiff written questions (interrogatories), demand for production of documents, and requests for admissions. Once received, the responses and documents should give you a better picture of what is being claimed and whether the plaintiff has evidence to support its claim.
