The 30-Day Deadline
Under California Code of Civil Procedure Β§ 412.20, you have 30 calendar days from the date you were served to file a response. If you were served by substituted service (left with someone else or posted), you may have 40 days. Miss this deadline and the plaintiff can request a default judgmentβmeaning they win without you ever getting to tell your side.
What Counts as Your Response Date?
- Personal service: 30 days from the date you personally received the papers
- Substituted service: 40 days from the date of mailing (10 days added)
- Service by publication: 30 days after last publication date
- Out of state: 30 days plus additional time may apply
Check your Proof of Service carefully. The date matters.
