Text Messages and Digital Evidence in California Legal Cases

Yes. Text messages, emails, voicemails and social media messages can be used as evidence in a California civil sexual abuse case. California law treats them as writings. To be used in court, a message generally has to be shown to be genuine, and it has to fit within the hearsay rules, which govern out-of-court statements.

The focus here is civil claims, meaning lawsuits a survivor brings for money damages against an abuser and, in many cases, against an institution such as a school, church, youth organization or healthcare provider that allegedly failed to protect them.

What Makes a Text Message 'Evidence' Under California Law

California Evidence Code § 250 defines a "writing" as handwriting, typewriting, printing, photographs, electronic mail, "and every other means of recording upon any tangible thing, any form of communication or representation, including letters, words, pictures, sounds, or symbols," regardless of how the record is stored. A text message, a direct message on a social platform, an email and a saved voicemail all fit within that definition.

In civil litigation, this material is usually called electronically stored information, or ESI. The term covers texts, DMs, emails, voicemails, photos and the metadata attached to them. Metadata is the background data a device or platform records, such as when a message was sent, from which number or account, and on what device.

Courts look at what a message shows, not at whether the person who kept it reacted "correctly." Digital material is one part of a broader picture; the site's overview of evidence in a sexual abuse lawsuit explains how claims are built from many kinds of proof.

Authentication: How California Courts Verify Digital Messages

Authentication is the step of proving a document is what it claims to be. Under California Evidence Code § 1400, authentication means introducing "evidence sufficient to sustain a finding that it is the writing that the proponent of the evidence claims it is." Evid. Code § 1401 adds that authentication "is required before it may be received in evidence."

For a text message, the question is usually who sent it. A message showing a contact name proves very little by itself, because contact names can be edited. Courts therefore look for context connecting the message to a particular person. Common ways of doing that include:

• testimony from the person who received or sent the message
• phone carrier records showing communication between two numbers at the relevant time
• metadata showing the date, time and account
• screenshots that display the phone number or account handle, not only a nickname
• content that only the claimed sender would likely know, or a reply that responds to it

A screenshot is a useful starting point. But the original device, or a forensic copy of it (an exact, verified duplicate made by a trained examiner), generally makes authentication considerably stronger, because it carries the underlying data a screenshot does not.

Preservation: What to Do With Digital Evidence Before It Disappears

Spoliation is the legal term for the destruction or loss of evidence. It becomes a legal problem when evidence is lost after a duty to preserve it has arisen. That duty generally begins when litigation is reasonably anticipated, which can be well before a lawsuit is filed.

California Code of Civil Procedure § 2023.030 allows courts to sanction misuse of the discovery process. The available sanctions include monetary sanctions, an order treating certain facts as established, an order barring a party from introducing certain evidence, and in serious cases orders striking pleadings, dismissing an action or entering a default judgment. The section also generally protects a party from sanctions for electronic information lost through the "routine, good faith operation of an electronic information system," while stating that this protection does not change any obligation to preserve discoverable information.

For someone holding messages that may matter, the practical steps people commonly take are simple:

• not deleting messages or conversation threads, including ones that are painful to keep
• backing messages up to a secure location that only they control
• not factory-resetting, trading in or discarding an old phone
• writing down, privately, the approximate dates of messages that seem important

Cloud backups such as iCloud or Google Drive may hold copies of messages even if a phone is lost, broken or replaced. Phone carriers also keep records of when texts were sent and received, though often not their content, and those records can be reached by subpoena in a civil case. The site's guide on what evidence to preserve covers non-digital material as well.

Discovery and Electronic Evidence in California Civil Cases

Discovery is the formal process, after a lawsuit is filed, by which each side obtains evidence from the other. California Code of Civil Procedure § 2031.010 allows any party to demand that another party produce documents, tangible things and "electronically stored information in the possession, custody, or control" of that party for inspection, copying, testing or sampling.

Code Civ. Proc. § 2031.030 sets out how those demands are made. Each demand must describe the items sought specifically or by reasonably particular category, and the demanding party "may specify the form or forms in which each type of electronically stored information is to be produced." The demand generally must allow at least 30 days for the response.

In a sexual abuse case, a survivor's attorney can use this process to seek text messages, emails, social media messages and device data from the abuser. Where an institution is a defendant, discovery can reach its internal emails, reports and records, which is often how a claim of negligent supervision or negligent retention in abuse cases is proven.

Discovery runs in both directions. The other side may ask a survivor to produce their own messages. Courts generally balance how relevant the material is against the burden and intrusion of producing it, and the parties must meet and confer to try to resolve disagreements before asking a judge to decide. The California Courts self-help center describes the civil process in general terms.

Criminal cases follow a separate discovery framework, which the site's comparison of civil and criminal cases explains.

Privacy Protections and the California Electronic Communications Privacy Act

The California Electronic Communications Privacy Act, known as CalECPA, begins at California Penal Code § 1546. It governs how a government entity, which § 1546 defines as a state or local department or agency or a person acting on its behalf, may obtain electronic information. Under CalECPA, law enforcement generally needs a warrant, a wiretap order or specific consent to compel a phone carrier or platform to hand over message content or device data. Penal Code § 1546.4 allows a person to move to suppress electronic information obtained in violation of the act.

CalECPA concerns government access. It does not govern a civil lawsuit between private parties, where messages are sought through discovery, subject to objections and court oversight.

That civil process has its own privacy limits. The California Constitution expressly lists privacy as an inalienable right, and California courts weigh that right against a party's need for discovery. Requests that reach into a survivor's unrelated personal life can be challenged.

Nothing in CalECPA prevents a person from voluntarily giving their own communications to their attorney. Messages deleted from a device may sometimes still exist with the platform for a period of time.

Hearsay, Exceptions, and When Digital Messages Come In

Under California Evidence Code § 1200, hearsay is "evidence of a statement that was made other than by a witness while testifying at the hearing and that is offered to prove the truth of the matter stated." Except as provided by law, hearsay is not admissible.

A text message offered to prove that what it says is true is hearsay. A message offered only to show that it was sent, or that contact happened, may not be. Three exceptions come up often in abuse cases:

• Party admissions. Evid. Code § 1220 provides that a statement is not excluded by the hearsay rule "when offered against the declarant in an action to which he is a party." In plain terms, messages written by the person a survivor is suing are often admissible against them, which makes this one of the most important exceptions for survivors.
• Then-existing state of mind or physical condition. Evid. Code § 1250 generally allows a statement of the declarant's "then existing state of mind, emotion, or physical sensation," including fear, intent or pain, when that state is itself at issue or explains the person's conduct. It does not cover statements of memory or belief offered to prove the fact remembered.
• Spontaneous statements. Evid. Code § 1240 covers a statement describing an event the speaker perceived, made spontaneously "while the declarant was under the stress of excitement caused by such perception." A message sent in the immediate aftermath of an event may qualify.

A message that would be hearsay for one purpose can sometimes come in for another, such as showing its effect on the recipient or a pattern of contact. The analysis is message by message.

Working With an Attorney on Digital Evidence in California

With digital evidence, an attorney typically assesses whether messages can be authenticated, identifies preservation concerns, considers which messages may be admissible and under what theory, and plans what to seek from the other side in discovery. The site's step-by-step overview of how a civil lawsuit works places these steps in the larger process.

A digital forensics examiner is a separate professional who can recover deleted messages, extract metadata or create a forensic image of a device. Not every case needs one; often the messages already preserved are sufficient.

If You Have Questions About What You Have, Privately

If someone sexually abused or assaulted you in California, you may have the right to pursue a civil claim against that person and, in some cases, against an institution that failed to protect you. A civil claim allows a survivor to seek compensation, which may include damages for emotional harm, the cost of therapy and medical care, lost income, and other losses the law allows. California has extended and revived filing deadlines for many abuse claims, so options may exist even when the abuse happened many years ago.

A confidential case review with Justice for Survivors looks at whether a claim may be available, which deadlines may apply, and whether the messages or records you have can be preserved and used. It is private and free, and it creates no obligation. You do not need to describe what happened, gather your phone records or organize anything first in order to ask a question, and you can reach out by whichever channel feels safest. This article is not asking you to decide anything today.

To ask a private attorney what this may mean for your situation, call Justice for Survivors at (866) 694-1630 for a confidential case review.
