Before you start How do I find the form? The form you need to respond to an eviction case is Answer - Unlawful Detainer-Eviction (form UD-105).If you get a Summons (form SUM-130), this means your landlord started a court case asking a judge to order you to move out - to evict you. The California Unlawful Detainer complaint is served to the tenant along with the Unlawful Detainer Summons when the tenant has violated the lease agreement. You can serve the defendant with just the Summons and Complaint. Even if you win, the people who are not named in the Complaint do not have to leave right away. The tenant isn't allowed any time to fix the violation, and if the tenant doesn't move out within three days, the landlord can file an eviction lawsuit. You have 5 days from the date you were served to respond in writing to the landlord's complaint and file your response with the court. The first step is to serve your tenant with the initial Notice, which will inform them of the issue and what is required of them to resolve it. Prepare the Required Documents: To initiate the lawsuit, landlords must file the following forms with the appropriate court.
