Why you can't do it yourself
It sounds strange the first time you hear it: you filed the case, you know exactly where the defendant lives or works, and you still aren't allowed to hand them the paperwork. The rule exists so a defendant can't later claim they were pressured, harassed, or never actually notified by the person suing them. Because the rule catches so many people off guard, it's the single most common reason a small claims case gets delayed or thrown out — not because the claim was weak, but because of who delivered the papers.
Who is allowed to serve
- Any adult who is not a party to the case — a friend, relative, or coworker, as long as they aren't you or a co-plaintiff.
- The county sheriff or marshal, for a modest fee.
- A registered process server — a person or company bonded and registered with the county specifically to do this (Bus. & Prof. Code § 22350 et seq.).
- For some business defendants, certified mail to the registered agent for service can satisfy the requirement — worth confirming for your specific defendant type before relying on it.
The deadline that actually matters
Your hearing date sets a countdown running backward: service generally has to be completed at least 15 days before the hearing if the defendant lives in the same county as the court, or 20 days if they're elsewhere. After that, proof that service happened — filed on the court's own proof-of-service form — is due at least 5 days before the hearing. Miss either deadline and the case is typically postponed to a new date rather than heard that day, which starts the clock over.
If service doesn't go through
A process server who can't locate or reach the defendant after a reasonable attempt will usually tell you, and most counties allow a continuance to try again or attempt a different method, like substituted service. It's frustrating, but it's routine — better to hear it from a process server before your hearing date than to find out from the judge on the day of.
