Responding to an Unlawful Detainer Lawsuit in California
Receiving eviction papers can make it difficult to focus on anything else. The first priority is identifying what you received and protecting your opportunity to respond. A California unlawful detainer lawsuit moves quickly, and explaining your position to the landlord does not replace a response in court.
This guide concerns tenants named as defendants in California residential eviction cases. Unnamed occupants, foreclosure-related cases, and commercial rentals may require different procedures. Seek prompt help with the actual papers rather than relying on a general article to calculate your deadline.
Identify the papers you received
A landlord's notice, such as a notice to pay rent or quit, is different from a summons and complaint. The notice states a demand and a deadline. The summons and complaint mean a court case has been filed and call for a court response. Neither document, by itself, is a sheriff's order to remove you.
Keep every page and envelope. Note when the papers arrived, who received them, whether anything was mailed, and whether copies were posted. Check the court, case number, named defendants, and any hearing notices. Do not assume a roommate's response will protect your separate interests.
Confirm the response deadline immediately
For a named tenant personally served with the summons and complaint, the usual response period is 10 court days after service. Saturdays, Sundays, and judicial holidays are excluded. This rule took effect January 1, 2025; older references to a five-day initial response deadline are outdated. The ordinary 30-day civil-lawsuit rule does not apply. Code of Civil Procedure section 1167
Other methods, including substituted service and court-authorized posting followed by mailing, have different service-completion rules. Service through California's Safe at Home program also carries an additional statutory response period. Have the delivery facts, proof of service, applicable holidays, and any court order reviewed together. Do not treat the date you happened to read the papers as necessarily controlling.
Choose the response before filing
An answer lets you respond to the complaint's allegations and state applicable defenses. The current Judicial Council unlawful detainer answer form UD-105 is revised January 1, 2026. Read its instructions and verification carefully; do not simply deny everything or check every defense.
An answer is not the only possible response. If service or jurisdiction may be defective, ask a lawyer about that issue before filing or taking other action that could constitute an appearance. Procedural choices can affect whether an objection is preserved, and eviction motions have special timing rules.
If a private attorney cannot review the papers before the deadline, contact legal aid or the court's self-help center immediately. An unanswered request for assistance does not extend your time.
Support your defenses with facts
A defense must fit both the facts and the applicable law. Depending on the case, relevant issues may include an improper termination notice, payment records that contradict the claimed rent, serious housing conditions, retaliation, or state or local eviction protections. A disagreement with the landlord does not establish every listed defense. California Courts' defense guide
Gather the lease, notices, payment confirmations, messages, repair requests, photographs, and any inspection records. For example, if the complaint alleges an unpaid month that your records show was paid, identify the payment date, amount, recipient, and confirmation. Keep the complete record, including unfavorable communications. Do not invent dates or describe an assumption as something you witnessed.
Local protections depend on the property's location and coverage requirements. Give the reviewer the full rental address and relevant tenancy history.
Complete both service and filing
Preparing an answer is only part of responding. You must also arrange proper service on the landlord or the landlord's attorney and timely file the response with the court.
For the mail-service procedure described by California Courts, another adult who is at least 18 and not a party mails the answer and attachments. The tenant cannot perform that service personally. The server completes and signs the proof of service, commonly form POS-030, which is filed with the court. California Courts' answer-service instructions
Check local forms, filing methods, and fees; a fee waiver may be available. Keep the filed answer, proof of service, and filing confirmation. If filing electronically, check whether the court accepted the submission.
Keep preparing after the answer
Filing an answer does not finish the case. Either side may request trial, and the statutory schedule generally calls for trial within 20 days after that request, subject to permitted extensions. Review every new court paper promptly and prepare your evidence and witnesses. Code of Civil Procedure section 1170.5
Settlement discussions do not themselves pause deadlines. Have any proposed agreement or extension documented and checked before relying on it. Understand any payment, move-out, dismissal, or judgment terms before signing.
Treat default and lockout papers as urgent
A missed deadline, an entered default, and an eviction judgment are different stages. If you may be late, seek immediate help checking the court record. Once default is entered, an answer alone ordinarily will not reopen the case.
A sheriff's notice to vacate requires separate, urgent review. Do not assume submitting an answer or requesting relief stops enforcement. Available remedies depend on the record and procedural stage. California Courts' guide to eviction judgments
