# Service Protocol — California Pro Se

## Part 1: Service of summons and complaint (initial process)

### Governing law: CCP §§ 412.10–417.40

When you file a new civil case in California, you must serve the
**summons and complaint** on each defendant. The clerk issues a
signed, sealed summons (SUM-100). You must serve it within **60
days of filing** in an unlimited civil case (Code Civ. Proc.,
§ 583.210 requires service within 3 years for dismissal, but
courts apply their own case management timelines; LASC requires
service within 60 days under LASC Rule 3.26).

The **plaintiff cannot serve their own summons.** Service must be
made by a person who is at least 18 years old and not a party
(Code Civ. Proc., § 414.10).

### Methods of initial service

#### 1. Personal service (CCP § 415.10) — gold standard

Deliver a copy of the summons and complaint directly to the
defendant in person. The process server must be:

- At least 18 years old
- Not a party to the case

Use a licensed process server or the county sheriff. The
**registered process server** (listed with the county clerk)
carries presumptions of valid service in most disputes.

**Cost:** Sheriff service: $50–$100 per attempt (varies by county).
Private process server: $75–$150 per successful service; prices
vary by location.

**When complete:** At the moment of personal delivery.

#### 2. Substituted service (CCP § 415.20)

If after reasonable diligence (typically 3+ personal-service
attempts at different times) the defendant cannot be personally
served, you may substitute service by:

1. Leaving a copy of the summons and complaint with a **competent
   member of the household** (18 or older) at the defendant's
   residence or usual place of business; **AND**
2. **Mailing** a copy to the defendant at the same address on the
   same day or the next day.

Substituted service is complete on the **10th day after mailing**.
(Code Civ. Proc., § 415.20(b).)

Document the prior attempts carefully — the Proof of Service must
describe the reasonable diligence efforts.

#### 3. Service by mail with Notice and Acknowledgment of Receipt (CCP § 415.30)

Mailing the summons and complaint to a defendant **does not
constitute service** unless the defendant executes and returns
a Notice and Acknowledgment of Receipt form (Judicial Council
form POS-015 or equivalent).

- Mail the documents with two copies of the Notice and
  Acknowledgment and a pre-addressed, postage-paid return envelope
- Service is complete when the defendant **signs and returns** the
  acknowledgment (Code Civ. Proc., § 415.30(c))
- If the defendant refuses to return it, you must personally serve
  or substitute-serve; the defendant who refuses bears the costs
  of any required personal service (Code Civ. Proc., § 415.30(d))

This method is unreliable for defendants who may not cooperate.

#### 4. Service on a business entity (CCP § 416.10)

For corporations: serve the **registered agent** for service of
process (look up at the California Secretary of State website:
https://bizfileonline.sos.ca.gov/) or any officer or agent
authorized to accept service.

For LLCs: serve the registered agent, any manager (managed LLC),
or any member (member-managed LLC) (Code Civ. Proc., § 416.40).

#### 5. Service by publication (CCP § 415.50)

Last resort — requires a **court order** after demonstrating that
the defendant cannot be served by any other method through
reasonable diligence. The summons is published in a newspaper
of general circulation in the county for 4 consecutive weeks.

Apply using forms SUM-100 and accompanying declaration showing
diligent search.

### After service: Proof of Service of Summons (POS-010)

After service, the process server completes and signs **POS-010**
(Proof of Service of Summons). This form is mandatory — it is
the court's record that service occurred.

File the original POS-010 with the court. Retain a copy.

If service was by personal or substituted service, the server
must state:

- Date, time, place of service
- Manner of service
- Name and description of person served (for substituted service)
- For substituted: description of household member and mailing date

### Serving out-of-state defendants (CCP § 413.10)

California summons may be served on out-of-state defendants by
the same methods listed above, subject to the law of the state
where service occurs. For most states, personal service by a
private process server is the practical method.

## Part 2: Service of motions and other papers after filing

### Governing law: CCP §§ 1010–1020

After the initial complaint is served, all subsequent filings
and papers are served under Code of Civil Procedure sections
1010 through 1020.

### Methods

#### 1. Electronic service (CCP § 1010.6)

California courts have broadly expanded mandatory electronic
service. Key rules:

- **Represented parties:** Electronic service on a represented
  party is **permitted** when the party (or their attorney) has
  consented to electronic service, either expressly or by
  registering for an electronic filing system (Code Civ. Proc.,
  § 1010.6(a)(2)).
- **Pro se parties:** Electronic service on a self-represented
  litigant requires **affirmative written consent** (Code Civ.
  Proc., § 1010.6(a)(2)(A)(i)). You cannot electronically serve
  an In Pro Per litigant without their consent.
- **Electronic service adds 2 court days** to any deadline computed
  from service (Code Civ. Proc., § 1010.6(a)(4)) — same as mail
  in most contexts.
- Many courts now mandate electronic filing (eFiling), which
  typically constitutes electronic service on registered parties
  simultaneously.

**Practical note for In Pro Per defendants:** Consent to electronic
service at the outset (provide your email address to opposing
counsel in writing). It is faster, cheaper, and eliminates
disputes about whether mail was received.

#### 2. Service by mail (CCP § 1013)

Service by depositing a copy in a sealed envelope addressed to
the party's last known address, with first-class postage prepaid,
in the U.S. mail.

**The 5-day mail extension:** When service is by mail within
California, **5 calendar days** are added to any period for
response or right to do any act (Code Civ. Proc., § 1013(a)).
This is the most commonly missed deadline extender in California
practice.

For mail outside California but within the U.S.: 10 additional
days (Code Civ. Proc., § 1013(b)).
For mail outside the U.S.: 20 additional days (Code Civ. Proc.,
§ 1013(c)).

**Example:** If a motion is noticed for hearing in 21 days, and
service is by mail within California, the notice period is
effectively 16 calendar days from mailing (21 - 5 = 16 days
minimum mailing lead time).

#### 3. Personal delivery (CCP § 1011)

Delivering a copy directly to the party or their attorney's
office. No extension added to deadlines.

#### 4. Overnight delivery (CCP § 1013(c))

If using a commercial messenger or overnight delivery service,
**2 additional calendar days** are added to response periods
(Code Civ. Proc., § 1013(c)).

### Notice periods for motions

Under California Rules of Court, rule 3.1300(a) and Code of Civil
Procedure section 1005(b), the **minimum notice** for most civil
motions is:

- **16 court days** before the hearing (plus service extensions)
- Plus **5 calendar days** if served by mail within California
- Plus **10 calendar days** if served by mail outside California
  but within the U.S.
- Plus **2 court days** if served by electronic service
- Plus **2 calendar days** if served by overnight delivery

**Summary for typical in-state mail service:**
- Hearing must be at least **21 calendar days** after the date of
  mailing the motion papers (16 court days + 5-day mail extension;
  convert court days to calendar days accounting for weekends and
  holidays)

**Summary judgment:** Notice must be given **75 days** before the
hearing (Code Civ. Proc., § 437c(a)(2)), plus service extensions.

## Proof of Service forms

### POS-010 — Proof of Service of Summons

Use for **initial service** of the summons and complaint.
Completed by the process server (not the plaintiff).
File with the court after service.

### POS-030 — Proof of Service by First-Class Mail

Use to prove **mail service** of any document after the initial
complaint. Completed by the person who mailed the document (the
plaintiff or their assistant — not the attorney if you are In Pro
Per, because you cannot serve your own summons, but you CAN mail
subsequent documents yourself).

Template:

```
                  PROOF OF SERVICE BY MAIL
               (Code Civ. Proc., § 1013a(3))

I am a citizen of the United States and a resident of the
County of [County]. I am over the age of eighteen years and
not a party to the within entitled action. My business address
is [address].

On [date], I served the following document(s):

    [List all documents served]

by placing a true and correct copy thereof in a sealed
envelope addressed as follows:

    [Name of party/attorney served]
    [Street address]
    [City, State, ZIP]

and depositing said envelope in the United States mail at
[city], California, with first-class postage thereon fully
prepaid.

I declare under penalty of perjury under the laws of the
State of California that the foregoing is true and correct.

Executed on [date] at [city], California.

____________________________
[Name]
```

### POS-040 — Proof of Personal Service

Use to prove **personal service** of any document (not initial
summons — use POS-010 for summons; use POS-040 for other
personally delivered papers).

## Service best practices for In Pro Per litigants

### 1. Photograph mailed envelopes before and after

Before mailing: photograph the front of the envelope showing the
address and contents list. After mailing at the post office:
keep the receipt showing date of mailing and certified/tracking
number.

### 2. Use Certified Mail for critical filings

For motions with tight deadlines, mail service disputes can
knock out your filing. USPS Certified Mail with Return Receipt
Requested (green card) provides:

- A postmarked receipt (proof of mailing date)
- The signed return receipt card (proof of receipt)

Cost: approximately $4-5 per piece.

### 3. Memorialize every communication

After any phone call or in-person meeting with opposing counsel,
immediately send a short email: "To confirm our call today:
[summary of what was agreed]." If opposing counsel later disputes
the call, the email is contemporaneous evidence.

### 4. Keep a service log

| Date | Document | Method | Recipient | Tracking / Receipt | Notes |
|------|----------|--------|-----------|-------------------|-------|
| 04/15/25 | Motion to Compel | USPS Certified + email | Atty. Jones | EJ123456789US | |

Update this log after every service event.

### 5. Consent to electronic service early

File a short notice or include in your first filing: "Defendant
John Doe, In Pro Per, consents to electronic service at the
following email address: [email]." This eliminates the 5-day
mail extension running against you, speeds up receiving filings,
and avoids disputes about whether mail arrived.

## Common service mistakes in California

| Mistake | Consequence |
|---------|-------------|
| Plaintiff serves their own summons | Service void; default judgment may be set aside (Code Civ. Proc., § 414.10) |
| Missing POS-010 after service of summons | Cannot enter default without proof of service |
| Failing to add 5 days for in-state mail | Miscomputed deadlines; premature motions |
| Electronic service to In Pro Per without consent | Service may be invalid (Code Civ. Proc., § 1010.6(a)(2)) |
| Wrong address on substituted service | Service invalid; re-serve |
| Forgetting that substituted service is complete on day 10 after mailing | Miscalculated response deadline |
| Not checking if defendant has registered agent | Serving a corporation at the wrong address is void |
| No Certificate of Service / POS on filed motions | Clerk may reject; court may not consider the filing |
