California has 58 counties, 58 superior courts, and one civil procedure code that governs how legal documents get from a court file to the person who needs to receive them. This is the long version of what every paralegal learns in their first year of litigation work — and what every pro se litigant has to figure out fast.
What service of process actually is
Service of process is the formal serving of a court document — a summons, a complaint, a subpoena, a notice — on the person who needs to receive it. The court will not move your case forward without proof that the other party was served correctly. The proof is a sworn affidavit by the person who served the papers.
In California, the rules live in the Code of Civil Procedure (CCP) sections 415.10 through 415.95. The most common methods:
- Personal service under §415.10 — in-hand serve on the named party
- Substituted service under §415.20 — leaving with a competent adult at the dwelling or workplace, then mailing
- Service by mail with acknowledgment under §415.30 — uncommon in litigation
- Service by publication under §415.50 — last-resort after court order
- Posting under §415.45 (real-property cases) and §415.46(c) (unlawful detainer) — last-resort after court order
The default rule is personal service. Everything else requires either statutory authorization (UD has its own §415.46 substituted-service rule) or a court order based on a diligence record.
Who can serve papers in California
Under CCP §414.10, any person 18 or older who is not a party to the action may serve process. Two practical caveats:
First, California Business and Professions Code §22350-22360 requires anyone who serves more than 10 papers a year for compensation to register as a process server in the county where they live. Each individual server holds their own county registration. Servd, as an entity, registers under BPC §22440 as a process serving company.
Second, even though anyone over 18 can theoretically serve, you do not want a party's friend or relative serving papers. The affidavit will be challenged, the service can be voided, and your case timeline restarts. Use a registered server.
Deadlines that matter
Service has to land inside several overlapping windows depending on case type:
- Summons after filing — CCP §583.210 requires service within 3 years of filing or the case is subject to mandatory dismissal under §583.250
- Practical window — most cases need service well before 3 years to keep the hearing calendar tight
- Hearing-pegged motions — most civil motions need to be served at least 16 court days before the hearing under CCP §1005(b), plus 5 days for mail
- Unlawful detainer — the answer is due 5 days after service under §1167
- Family law — RFOs and other hearing-pegged motions follow §1005, with their own family-code wrinkles
- TROs and protective orders — service must complete before the hearing date listed on the order
A defective service can be cured but the cost is time. Time you may not have.
What things cost
Process serving fees vary across vendors. Servd nationwide rates (single tier, no B2B/B2C split):
- Standard service: $99 (up to 5 attempts, 3-5 business days)
- Rush: $159 (24-48 hours)
- Expedited: $229 (same-day)
- Sub-service: priced as Standard ($99)
- Posting: $125
- Skip trace add-on: $80 flat
Volume discount applies to law firms with 11+ cases per month: 5% (11-25), 10% (26-50), 15% (51-100), 20% + account manager (101+). Individual consumers pay list price; volume firms qualify automatically.
What can go wrong
The five most common service problems we see:
1. Wrong defendant served — paralegals occasionally provide the wrong address from intake. The remedy is reserve at the correct address; the affidavit at the wrong address is voided. 2. Sub-service before diligence — a server leaves the papers with a roommate on the first attempt without documenting that the named party was unavailable. Sub-service requires reasonable diligence first. 3. Missing the mailing step — substituted service under §415.20 is incomplete without the mailing follow-up. Service is deemed complete 10 days after mailing. 4. Defective declarant language — the affidavit needs the CCP §2015.5 perjury statement, the server's name, the date, the place. Missing any element and the affidavit is challenged. 5. Stale address — the address in the complaint is from intake six months ago. Skip trace at intake costs $80 flat and saves a week.
When to use a professional
For any active litigation matter, use a registered process server. The fee is a fraction of the cost of refiling a defective service. For pro se matters, the court self-help center is the right starting point for the procedural questions; the service work itself is mechanical and a registered server is still the right choice.
Servd is one option. Most counties have a working pool of independent registered servers as well. The decision matters less than getting it right.
