📋 What Is Unlawful Detainer?
An unlawful detainer (UD) is the legal name for an eviction lawsuit in California and several other states. When a tenant stays in a rental unit after their right to possession has ended — whether because the lease expired, rent went unpaid, or a lease was violated — their continued possession of the property is “unlawful detention” of the landlord’s property. The lawsuit to reclaim possession is the unlawful detainer action. In plain terms: unlawful detainer is eviction by another name in . 🏠

⚖️ UD vs. Eviction — Is There a Difference?
In most contexts, “unlawful detainer” and “eviction” refer to the same legal proceeding. The terminology differs by state:
| State | Term Used |
|---|---|
| California | Unlawful Detainer (UD) — filed in Superior Court |
| Texas | Eviction (also called “forcible detainer”) — filed in Justice Court |
| New York | Summary Proceeding — filed in Housing Court |
| Florida | Eviction — filed in County Court |
| Illinois | Eviction — filed in Circuit Court |
| Colorado | Unlawful Detainer — filed in County Court |
📋 When to File an Unlawful Detainer
You file an unlawful detainer when:
- 💰 Tenant failed to pay rent and the pay-or-quit notice period has expired
- 📋 Tenant failed to cure a lease violation after the cure-or-quit notice period expired
- 📅 Tenant has not vacated after a termination of tenancy notice expired
- 🏠 Tenant is a holdover and refuses to leave after lease expiration
⚠️ File Immediately After Notice Expires
Every day you delay after the notice period expires costs you rent you’ll never recover. File the UD complaint the same day the notice period runs — don’t wait to see if the tenant might leave voluntarily. Getting on the court calendar quickly is the only way to control your timeline.
🏛️ The UD Process (California Example)
- Serve Proper Notice — 3-day, 30-day, 60-day, or 90-day notice depending on the reason and tenancy length.
- File UD Complaint — File with the Superior Court (limited civil division) after the notice period expires. Pay filing fee ($240–$385 in California depending on amount claimed).
- Serve Summons and Complaint — Personal service, substituted service, or posting+mail per CCP requirements.
- Wait for Response — Tenant has 5 days to file a written response after service. If no response: request default judgment.
- Trial (if Contested) — Hearing typically scheduled 20 days after filing. Brief hearing (30–90 minutes). Judge decides.
- Judgment for Possession — If landlord wins, obtain Writ of Possession from clerk.
- Sheriff Lockout — Deliver writ to Sheriff. Sheriff posts 5-day notice then executes lockout on scheduled date.
⚖️ The UD Judgment — Possession and Money
A UD judgment can include two components:
- 🔑 Possession — judgment granting the landlord return of the property (always sought in UD)
- 💰 Money judgment — for unpaid rent, damages, and costs (request this at the hearing)
Winning possession does not automatically collect the money owed. To collect unpaid rent and damages, you must: request a money judgment at the UD hearing, then separately pursue enforcement (wage garnishment, bank levy, collections). 💰
📊 UD on a Tenant’s Record
An unlawful detainer filing — even one that was dismissed or settled — appears in court records and may show up in tenant screening reports. This is one of the reasons UD filings are such a significant screening signal. Even a dismissed UD often means the landlord had to escalate to court action, which is itself informative about the tenant’s history. 📋

❓ Frequently Asked Questions
An uncontested California UD typically takes 3–6 weeks from filing to lockout. A contested UD with a tenant who files a response and takes the case to trial can take 2–4 months or longer. In the San Francisco Bay Area and Los Angeles, contested cases can take 3–6+ months due to court backlog.
In California, tenants can “cure” a nonpayment UD by paying all past-due rent plus costs before judgment. After judgment is entered, the landlord can generally reject payment. In some circumstances, the landlord can also reject payment after the UD is filed if they choose not to accept the cure. Consult an attorney about your rights to reject payment once you’ve filed.
