Subpoena Service in San Diego: Legal Requirements and Common Mistakes

Subpoena service is one of the most technical areas of process serving. Because subpoenas compel compliance, California courts expect strict adherence to service rules. As a result, improper service can make a subpoena unenforceable.

What Is a Subpoena?

A subpoena is a court-issued command that requires a person or entity to appear in court, provide testimony, or produce documents and records. Therefore, service must follow California requirements closely.

Types of Subpoenas in California

Before service begins, you must confirm which subpoena type applies. In practice, each type carries specific notice and service requirements.

• Subpoena for Personal Appearance
• Subpoena Duces Tecum (documents or records)
• Deposition Subpoena
• Trial Subpoena

Who Can Serve a Subpoena in California?

California allows a registered professional process server, a county sheriff, or any adult (18+) who is not a party to the case to serve a subpoena. However, attorneys typically prefer professional service because subpoenas require strict compliance, proper handling of witness fees, and accurate Proof of Service.

How to Serve a Subpoena in California

To serve a subpoena correctly, follow a methodical process. Otherwise, the subpoena may fail before enforcement becomes possible.

1. Prepare the Subpoena

First, confirm the court, case number, and party names. In addition, verify that the subpoena form matches the correct subpoena type.

2. Include Required Witness Fees

Next, tender required witness fees at the time of service when the law requires them. This typically includes an appearance fee and mileage reimbursement.

3. Complete Personal Service

In most cases, the process server must personally hand-deliver the subpoena to the witness or custodian of records. Therefore, the server should plan service attempts strategically.

4. Document Service

After service, the server must complete a court-compliant Proof of Service that accurately reflects what occurred.

5. File Proof of Service

Finally, the party must file Proof of Service when required. Without this filing, enforcement and court appearance issues may arise.

Witness Fees: A Commonly Missed Requirement

One of the most frequent subpoena service mistakes is failing to include required witness fees. As a result, the subpoena may become unenforceable.

When witness fees apply, the process server should tender the statutory appearance fee and mileage reimbursement at the time of service. For this reason, professional service helps reduce avoidable failures.

Can Subpoenas Be Served by Mail?

Generally, no. Most California subpoenas require personal service. Although limited exceptions may apply in specific situations, service by mail is not the default method. Therefore, using the wrong method is a primary reason subpoenas are quashed.

Deadlines and Timing Matter

Subpoenas must be served with sufficient notice. If service happens too late, the receiving party may object, file a motion to quash, or refuse compliance. Consequently, attorneys and litigation staff should plan service early and track deadlines closely.

Common Subpoena Service Mistakes

Courts frequently see subpoenas fail due to avoidable errors. For example, parties use an improper service method, miss witness fees, misidentify the recipient, serve too late, or submit a defective Proof of Service.

These mistakes delay discovery and weaken enforcement. Therefore, accurate service and documentation matter from the start.

Proof of Service in Subpoena Cases

Proof of Service must clearly state the date, time, and location of service, the method used, and the identity of the person served. In addition, it should confirm whether the server tendered witness fees when required.

Because subpoenas are often challenged, documentation must be precise and consistent with California rules.

Local Practice Matters in San Diego

Local practice affects successful service. In San Diego, effective subpoena service often depends on courthouse procedures, business access protocols, and medical or corporate compliance practices. As a result, local experience improves acceptance and reduces disputes.

Frequently Asked Questions

Can a subpoena be left with someone else?

Generally no. Most subpoenas require personal service on the named witness or recipient.

What happens if service is improper?

The court may quash the subpoena, and the subpoena may become unenforceable.

Can a process server testify about subpoena service?

Yes. Professional process servers are prepared to testify if a party challenges service.

Final Thought: Subpoenas Require Precision

Subpoena service demands procedural accuracy. Therefore, professional service helps attorneys and paralegals maintain statutory compliance, protect enforceability, and rely on defensible Proof of Service.

Subpoenas work only when service is done correctly.
