Can Text Messages Be Used as Evidence in a Divorce?

Posted in Divorce on July 5, 2026

Divorce cases can become messy quickly. What you may have thought would be a civil dissolution can rapidly turn into a heated battle in which your spouse begins making false accusations against you.

If you and your spouse are in strong disagreement about topics like child custody or the division of assets, you might start searching far and wide for evidence to counter their accusations. Can text messages be used in divorce court? They can in California, as long as they are authenticated to prove that they came from the stated sender.

Your divorce lawyer can help you understand how to use text messages as evidence to support your case and why taking care to minimize text exchanges with your spouse may be wise.

Can You Use Text Messages as Evidence in California Family Court?

Text messages are admissible evidence in California family court under the California Evidence Code § 250 and § 1401. Evidence Code § 250 broadly defines a “writing” as handwriting, typewriting, printing, photographing, or other methods used to record a form of communication, including text messages.

Evidence Code § 1401 requires that all “writings” be authenticated before they can be admitted as evidence in court or before secondary evidence of their content may be received in evidence. Code § 1400 states that the party presenting the evidence must introduce facts sufficient to support a finding that the item is what it claims to be.

Under these codes, text messages can be used in California divorce court as long as they are properly authenticated. If you want to use text messages as evidence against your spouse, speak with your attorney about the authentication process and whether this evidence would be beneficial in your case.

Examples of How Text Messages May Be Used in Divorce Cases

Because text message evidence is generally admissible in California divorce court, it’s important to understand the different ways it can be used. You should be aware of how your own text messages could be used against you, as well as how you might leverage this evidence to support your case against your spouse.

These are a few common uses for text message evidence in divorce cases:

Child custody and visitation decisions: You might use electronic communications to show poor or neglectful parenting practices in support of you having majority custody. You could also use texts as evidence that your spouse’s accusations against you are false to support your fitness as a parent.
Evidence of abuse and harassment: Text messages with insults, threats, or derogatory remarks can be signs of abuse and harassment that could also impact custody decisions. If your spouse continuously degrades you over text, the court may question their ability to co-parent with you.
Evidence of financial problems: Text messages can serve as digital evidence of hidden assets or irresponsible spending habits that may also impact the divorce case, particularly in decisions regarding the division of property.
Evidence of infidelity: If your spouse was unfaithful during the marriage, having evidence of their infidelity through text messages may be helpful in custody or property decisions.

Remember that California is a no-fault divorce state, which means the court does not need evidence of fault or misconduct on the part of you or your spouse. In some states, using text messages to show evidence of infidelity may be helpful. But in California, this is usually unnecessary unless the infidelity was part of another problem, such as irresponsible spending.

The Process of Authenticating Text Messages

Can text messages be used in divorce court? They can, but you must authenticate them to show that they are legitimate and what you claim them to be. They also need to meet a few other standards to be generally admissible in California family court. Your divorce attorney can help you understand whether your text messages meet these standards and could be helpful in your case.

Proving the Legitimacy of the Messages

California law sets standards for the authentication of evidence to be used in court. For text messages to be authenticated, they must meet one of these requirements:

The person who wrote them admitted to sending them.
A witness saw the person write and send them.
The message’s context indicates that it is a response to an authenticated original message.
The message references information only the person in question would know about.

Showing That the Messages Are Relevant

For the court to accept text messages as evidence, they must also be relevant to the case. Text messages showing infidelity purely to pin fault for the divorce on your spouse may not be relevant in no-fault states like California. You would need to tie the message to actual issues being discussed in your case, such as child custody or the division of assets.

Demonstrating the Legality of the Acquisition

You must also lawfully obtain text messages for them to be admissible in court. You cannot hack into your spouse’s computer or steal their phone and take screenshots of the communications. If the court deems that you illegally acquired the messages, they may be rendered inadmissible.

Legal methods of obtaining the messages may include:

Taking screenshots of your own communications with your spouse from your device
Requesting text messages from your spouse during discovery
Issuing a subpoena to the cell phone provider to obtain text messages from your spouse (though federal law or technical restrictions may limit the carrier from providing the content of the messages)

When Third-Party Messages Are Admissible

California divorce courts typically accept only text messages between divorcing spouses. If you wish to use messages from a third party, that person may be required to testify under oath to the authenticity of the messages. Otherwise, the content of the messages may be considered “hearsay.”

Tips for Maintaining Responsible Communications During a Divorce Case

Text messages can be used against you in divorce court, so it is important to take caution when communicating with your spouse. The following tips can help you maintain mindful digital interactions during the divorce process:

Keep text conversations to a minimum. Avoid going into too much detail over text. Stick to the basics and have your attorney present during any longer interactions.
Avoid arguing over text. When you do need to text your spouse, keep the interaction professional. Arguments could be interpreted as hostility or aggression.
Do confirm details over text. If you are co-parenting with your soon-to-be-ex-spouse, it may be helpful to get details such as pickup times and locations in writing. Sending these over text and having your spouse confirm them can prevent confusion and misunderstandings that could be used as evidence of poor parenting.
