In an ordinary California injury action, the summons directs a written response within 30 days after service. Start with legally effective service and exclude the service day when applying the governing counting rules. Check holidays and valid extensions. Do not calculate from the collision date, complaint upload date, or the insurer’s first contact with counsel.
Documents and facts to assemble
- The issued summons and signed personal-service proof
- The response calendar and any written extension
Build a personal-service response timeline
For each served driver or vehicle owner, keep a separate record of the delivery date, the defendant named on the summons, and the person identified in the proof. Compare the signed proof with the process server’s notes before entering a response date. If several defendants were served on different days, use separate calendar entries rather than one deadline for the entire accident case.
Practical checklist
- Match the defendant’s name on the proof to the summons and complaint.
- Record the delivery date and time shown by the server, with the signed proof attached.
- Keep the original response calculation and any later written extension together.
Final review
Before acting on a missed response date, compare the service record, current docket, and any extension or court order. The proof-of-service guide below helps identify the records to review.
