Understanding Unlawful Detainer: A Landlord's Handbook

For landlords in Los Angeles, the term "eviction" is often used broadly to describe the process of removing a tenant. However, the precise legal term for the court action taken to regain possession of your property is "Unlawful Detainer." This lawsuit is the critical second phase of the eviction process, following the initial notice, and understanding its intricacies is absolutely essential for a successful outcome. Without a proper Unlawful Detainer action, you cannot legally compel a tenant to vacate, regardless of their lease violations or non-payment. Our firm specializes in expertly navigating this complex legal proceeding, ensuring landlords can efficiently regain control of their valuable assets.
The Purpose of Unlawful Detainer
An Unlawful Detainer lawsuit is a summary court proceeding, meaning it is designed to be expedited compared to other civil cases. Its sole purpose is for a landlord to regain possession of their rental property from a tenant who is unlawfully occupying it. This "unlawful occupation" typically arises when a tenant fails to comply with the demands of a properly served eviction notice (e.g., failing to pay rent after a 3-Day Notice to Pay Rent or Quit, or refusing to move after a 60-Day Notice to Terminate Tenancy).
It's crucial to distinguish the Unlawful Detainer from the initial eviction notice. The notice is a prerequisite, informing the tenant of the breach and the required action. The Unlawful Detainer is the actual lawsuit filed in court when the tenant fails to comply with that notice. Without a correctly drafted and served notice, an Unlawful Detainer lawsuit will likely be dismissed.
The lawsuit seeks a court order (a "Judgment for Possession") that formally terminates the tenant's right to occupy the property. While you can also seek monetary damages for unpaid rent and other costs within this lawsuit, the primary goal is always to regain possession.
Navigating the Unlawful Detainer Process
Once the eviction notice period expires and the tenant has not complied, the Unlawful Detainer process begins:
- Filing the Complaint and Summons: The landlord (through their attorney) files an Unlawful Detainer Complaint with the court, outlining the grounds for eviction. A Summons is also issued, which officially notifies the tenant of the lawsuit.
- Serving the Complaint and Summons: These documents must be formally served on the tenant by a professional process server. This service is highly regulated, and any error can lead to dismissal.
- Tenant's Response: After being served, the tenant has a limited time to respond. As of January 1, 2025, California's AB 2347 extended this response time from 5 to 10 court days (excluding weekends and judicial holidays) for residential properties. If the tenant files an "Answer," a trial will be scheduled. If no response is filed, the landlord can request a "Default Judgment."
- Trial or Default Judgment: If the tenant responds, a trial takes place where both sides present their arguments. If the tenant defaults or the landlord wins at trial, the court issues a "Judgment for Possession."
- Writ of Possession and Sheriff Lockout: With the judgment, a "Writ of Possession" is obtained. This writ is then given to the County Sheriff, who posts a final 5-day "Notice to Vacate" on the property. If the tenant does not leave, the Sheriff will physically remove them.
The Unlawful Detainer process is designed for speed, but its strict procedural requirements make legal expertise invaluable. Understanding each phase, meticulously adhering to timelines, and ensuring all documentation is flawless are paramount to a swift and successful tenant removal in Los Angeles.
