How the California eviction process actually works
An unlawful detainer is a court process with strict steps. Skipping one restarts it, which is why most failed evictions fail on procedure.

Eviction in California is a court proceeding called an unlawful detainer. It is deliberately fast compared with other civil litigation, and deliberately strict about procedure.
Self-help is unlawful
An owner cannot change the locks, remove a tenant's belongings, shut off utilities, or remove doors to force a departure. These are unlawful regardless of how far behind the rent is, and they expose the owner to damages and penalties that typically exceed the arrears.
The notice
Everything starts with a written notice, and its form depends on the reason. A notice for non-payment gives a period to pay or leave. A notice for a curable breach gives a period to fix it. Some terminations require a longer period and, where just cause rules apply, a stated cause.
Filing and response
If the notice period expires without compliance, the owner files an unlawful detainer complaint. The tenant has a short window to respond — much shorter than ordinary civil litigation.
A tenant who does not respond in time risks a default judgment. A tenant who does respond gets a trial date, usually quickly.
Trial and writ
At trial the court decides possession, and may decide money owed. If the owner prevails, the court issues a writ of possession, which the sheriff executes after posting notice. The sheriff performs the lockout, not the owner.
“Every stage has a deadline, and every deadline is short. That cuts both ways.”
Practical points
- Owners: have the notice reviewed before serving it. It is the cheapest point to catch an error.
- Owners: keep contemporaneous records of service.
- Tenants: respond within the deadline even if you intend to move; a default judgment follows you.
- Both: local rules and just cause ordinances can add requirements on top of the state process.
