Unlawful Detainer Appeals: What Happens After You Lose at Trial

California Tenant Defense System | Justice Foundation

Losing an unlawful detainer trial is not necessarily the end of your housing. California law provides several post-judgment options that can delay or reverse an eviction judgment, and understanding these options — and their timelines — is essential for tenants who lose at trial or by default.

Appealing a Judgment

A tenant who loses an unlawful detainer trial can appeal the judgment to the superior court appellate division. The appeal must be filed within 30 days of the judgment. In unlawful detainer cases, an appeal does not automatically stay the eviction — unless you post a bond in the amount of the judgment plus additional amounts. The appellate court reviews the trial record to determine whether legal errors were made; it does not hold a new evidentiary hearing. Appeals are most likely to succeed when the trial court made a legal error — misapplied the law, admitted evidence it shouldn’t have, or excluded evidence you needed.

Motion to Vacate a Default Judgment

If you received a default judgment — because you didn’t file a response to the unlawful detainer complaint within the 5-day deadline — you can file a motion to vacate the default. You must show that your failure to respond was due to mistake, inadvertence, surprise, or excusable neglect (under Code of Civil Procedure Section 473), and that you have a meritorious defense to the eviction. Time is critical — you must file promptly after discovering the default. Courts have discretion to grant or deny motions to vacate; a strong defense combined with a plausible explanation for the default gives the best chance of success.

Writ of Supersedeas

A writ of supersedeas is an emergency appellate court order staying the eviction while the appeal is pending. It requires showing: a likelihood of success on appeal, irreparable harm if the eviction proceeds, and that the balance of hardships favors the stay. Writs of supersedeas are difficult to obtain but can buy critical time while the appeal is reviewed. The Justice Foundation kit covers post-judgment options including appeal procedures, default motion templates, and the writ of supersedeas application process.
