A subpoena in a California criminal case is a formal court order requiring a person to appear in court to testify or produce physical evidence.
Under California law, prosecutors and criminal defense attorneys can issue subpoenas to compel compliance when voluntary cooperation fails.
Subpoenas play a vital role in protecting a defendant's Sixth Amendment right to present a defense and access evidence.
Because ignoring a subpoena carries severe legal consequences—including fines and jail time—understanding how subpoenas work, how they are served, and what rights you hold is essential.

What Is a Subpoena in a California Criminal Case?
A subpoena is an enforceable legal mandate issued under court authority. In California criminal proceedings, a subpoena officially requires an individual or entity to:
-
Appear in court to provide oral testimony under oath, or
-
Produce documents, records, or physical evidence for review.
A subpoena is not a request or an invitation—it is a mandatory court order. Failing to comply can result in serious legal penalties, including contempt of court.
Who Can Issue a Subpoena in California Criminal Proceedings?
Under California Penal Code provisions, several parties have the legal authority to issue subpoenas in a criminal case:
-
The Prosecutor (District Attorney or City Attorney)
-
The Criminal Defense Attorney
-
The Court Clerk (acting upon request of an attorney)
While attorneys prepare and issue these documents, the court enforces them. To be legally valid, a subpoena must be properly served by an individual who is at least 18 years old and not a party to the criminal case.
The 2 Primary Types of Subpoenas in California
California criminal law utilizes two main categories of subpoenas, depending on whether testimony or tangible evidence is needed.
|
Subpoena Type |
What It Compels |
Common Applications |
| Witness Subpoena | In-person attendance to testify in court | Preliminary hearings, motion hearings, jury trials, and sentencing |
| Subpoena Duces Tecum | Production of specific records or physical items | Medical files, phone logs, bank records, surveillance footage |
1. Witness Subpoenas
A witness subpoena orders a person to attend court on a specified date and time to give sworn testimony. If a properly served witness fails to appear, the judge may issue a bench warrant for their arrest, postpone the trial, or hold the witness in civil or criminal contempt.
2. Subpoena Duces Tecum (Production of Evidence)
A subpoena duces tecum (Latin for "bring with you under penalty") requires a custodian of records or organization to produce relevant documents or tangible materials.
Common records requested via subpoena duces tecum include:
-
Medical, psychological, and hospital records
-
Financial, banking, and business documents
-
Phone, text message, and cellular location logs
-
Insurance files and claims data
-
Security camera and video surveillance footage
-
Employment and payroll records
In most situations, the official custodian of records can submit certified copies directly to the court rather than testifying in person. Courts will reject or modify requests that seek irrelevant, overly broad, or harassing materials.
How Are Subpoenas Properly Served in California?
For a subpoena to be legally binding in a California criminal court, it must comply with strict rules of service:
-
Eligible Process Servers: Service must be completed by a law enforcement officer, a registered process server, or any neutral adult not named in the lawsuit.
-
Reasonable Notice: The recipient must be given sufficient time to prepare, locate requested records, or travel to court.
-
Personal Service vs. Mail: While certified mail service is permissible under limited conditions, personal in-hand service remains the standard for establishing undeniable proof of service.
Obtaining Records Without a Subpoena
Records can sometimes be obtained voluntarily if the owner or record subject signs a written privacy authorization form. However, if a party refuses to release documents—or if sensitive personal privacy rights are involved—a subpoena duces tecum is mandatory. In sensitive scenarios, judicial review or a formal court order may be required prior to disclosure.
Challenging a Subpoena: Filing a Motion to Quash
Receiving a subpoena does not automatically mean you must disclose every record or testify without limitation. Recipients have the right to challenge a subpoena by filing a legal action called a Motion to Quash.
Common legal grounds to quash or modify a subpoena include:
-
Irrelevance: The requested evidence bears no connection to the criminal charges.
-
Overbreadth: The scope of the request is excessively wide or burdensome.
-
Privilege: The material is protected under established legal privileges.
-
Undue Burden: Compliance imposes unreasonable expense, effort, or hardship.
-
Improper Service: The subpoena was served incorrectly under California law.
If the court grants the motion, it can completely invalidate the subpoena or modify its scope to protect the recipient.
Privileged Records and Constitutional Rights
1. Privileged Communications
California law protects specific confidential relationships. Courts carefully weigh an accused person's right to evidence against these statutory privacy protections.
Protected privileges include:
-
Attorney-Client Privilege
-
Psychotherapist-Patient Privilege
-
Physician-Patient Privilege
-
Clergy-Penitent Privilege
2. The Fifth Amendment Right Against Self-Incrimination
Under the Fifth Amendment to the U.S. Constitution, a witness cannot be forced to give testimony that could incriminate them in a crime.
Important Note: You cannot simply ignore a subpoena because you wish to invoke the Fifth Amendment. You must appear in court (or have your defense lawyer appear on your behalf) to formally assert your constitutional right on the record.
Consequences of Ignoring a Subpoena in California
Ignoring a valid court subpoena carries swift statutory penalties under California law.
If you fail to appear or produce required documents, a judge may issue:
-
An immediate bench warrant for your arrest
-
Formal contempt of court charges
-
Financial fines up to $1,000
-
Up to six months in county jail

Frequently Asked Questions (FAQs)
Can a defense attorney subpoena police records in California?
Yes. Criminal defense attorneys can issue subpoenas for police records, officer body-cam footage, dispatch logs, and internal department reports, provided the requested items are relevant to the defense and comply with California discovery rules (such as Pitchess motions for officer personnel files).
Can a witness refuse to testify after receiving a subpoena?
A witness cannot simply refuse to show up. However, if answering specific questions could expose the witness to criminal liability, they may formally invoke their Fifth Amendment privilege against self-incrimination in court.
What should I do if a subpoena demands confidential or private records?
If a subpoena requests privileged or highly confidential information—such as medical files or trade secrets—you should consult a lawyer immediately to file a Motion to Quash or request a protective order before producing the documents.
What happens if I received a subpoena by mail in California?
While personal service is standard, some California subpoenas sent by mail include an Acknowledgment of Receipt. If you do not sign and return the receipt, the subpoena may not be enforceable until personal service is formally executed. Consult an attorney to determine your legal obligations.
Do I need a criminal defense lawyer if I am only a subpoenaed witness?
Yes, consulting a lawyer is strongly recommended if testifying or producing documents could expose you to criminal charges, breach confidential agreements, or force disclosure of private records. A defense lawyer ensures your constitutional rights remain protected throughout the proceeding.
