Can Text Messages Be Used in a Custody Case?

Yes. Text messages can be used in court in a New York custody case when they are relevant and properly authenticated, meaning someone can show who sent them and that they are accurate. October is Cybersecurity Awareness Month, a reminder that how you collect digital evidence matters as much as what it says.

At Cedeño Law Group, PLLC, attorney Peter L. Cedeño and our NYC child custody attorneys represent parents in Manhattan, Brooklyn, Queens, the Bronx, and Staten Island in Family Court and in the Supreme Court matrimonial part. Our NYC child custody lawyers build the record from the first meeting, and in most custody cases today, a large part of that record lives on a phone.

If you are in a custody dispute and have messages you think the judge should see, contact Cedeño Law Group, PLLC to schedule a confidential consultation.

Are Text Messages Admissible in Family Court in New York?

Text messages are generally admissible in New York Family Court and in the Supreme Court matrimonial part if they are relevant to an issue in the case and can be authenticated. The judge decides whether each message comes in and how much weight it deserves, based on the facts and the evidence rules.

Relevance in a custody case is broad. The central question is the best interests of the child, so messages that show how each parent communicates, cooperates, supports the child’s relationship with the other parent, handles schedule changes, and responds to the child’s needs can all matter.

The other parent’s own messages are usually the easiest to use. Statements a party made themselves can generally be offered against that party. Your own messages can be used against you in exactly the same way, which is why what you send during a custody dispute deserves as much care as what you receive.

How Do You Prove a Text Message Is Real?

Authenticating a text message means showing the court it is what you say it is. That can be done through testimony from the person who received it, the phone number it came from, details in the message only the sender would know, the context of the conversation, and, when needed, phone carrier records or a forensic extraction of the device.

Most text messages are authenticated through ordinary testimony. A parent testifies that they know the other parent’s number, that they received the messages on specific dates, and that the screenshots are accurate copies. If the other side denies sending a message, the dispute may require more proof, such as subpoenaed phone records showing the messages were sent between the two numbers.

Credibility matters here too. A judge who sees a complete, consistent thread is more likely to trust it than a handful of cropped screenshots with no dates.

Can Screenshots of Text Messages Be Used in Court?

Yes, screenshots can be used, but how they are captured affects how much weight they carry. The best screenshots show the full thread, the date and time of each message, and the phone number or contact name. Keep the original messages on the phone, and never edit, crop, or reorder them.

To preserve text messages for a custody case:

• Take screenshots that show the sender’s number or contact information, not just a nickname
• Capture the dates and times of every message, including earlier and later messages that give context
• Do not delete the original messages or the conversation from your phone
• Back up the phone to a secure account the other parent cannot access
• Export full conversations when possible, rather than relying only on screenshots
• Keep a simple log listing the date, time, and subject of important messages

Selective screenshots can backfire. If the other side produces the rest of the conversation and it changes the meaning, the judge may question everything else you offer.

What Kinds of Text Messages Matter in a Custody Case?

Messages that show how each parent behaves toward the child and toward the other parent carry the most weight. That includes threats, harassment, refusals to follow the parenting schedule, missed pickups, interference with the child’s relationship with the other parent, and messages showing substance use or unsafe decisions.

Text messages can also show the positive side of a parent’s record. A long history of calm, child-focused messages about school, doctor’s appointments, and schedule changes can be powerful evidence of a parent who supports cooperation.

Common categories of messages that come up in custody cases include:

• Threats or harassment directed at the other parent
• Refusals to return the child or to follow the parenting time schedule
• Messages showing a parent regularly cancels or misses time with the child
• Attempts to keep the child from speaking with the other parent
• Messages sent directly to the child that involve the child in the adult conflict
• Statements about alcohol or drug use, unsafe driving, or leaving the child unsupervised
• Admissions about income, spending, or plans to relocate with the child

Threatening or harassing messages can also support a family offense petition in Family Court. Our NYC order of protection attorneys can review whether the messages fit.

Can Your Own Text Messages Hurt Your Custody Case?

Yes. Everything you send during a custody dispute can end up in front of the judge. Angry, sarcastic, or insulting messages to the other parent, messages that criticize the other parent to the child, or messages that ignore reasonable requests can all hurt how a judge views your judgment and your willingness to cooperate.

A simple rule helps: write every message as if the judge will read it, because the judge might. Keep messages short, factual, and focused on the child. Respond to scheduling questions directly. Do not argue about the case over text. If a message makes you angry, wait before responding.

Some parents use a co-parenting app that keeps a time-stamped record of every message and cannot be edited after sending. Judges sometimes order parents in high-conflict cases to communicate only through one of these apps. Even without an order, using one can create a cleaner record.

Can You Use Messages Taken From the Other Parent’s Phone?

Be very careful. Secretly accessing another person’s phone, email, or social media account without permission can be illegal in New York, and communications intercepted without consent can be kept out of court. Installing monitoring apps on another adult’s phone can also expose you to criminal and civil consequences.

In 2023, the New York Attorney General secured $410,000 from a group of companies selling so-called stalkerware apps that let users secretly monitor another person’s calls, texts, photos, and location. As Attorney General Letitia James put it, “Snooping on a partner and tracking their cell phone without their knowledge isn’t just a sign of an unhealthy relationship, it is against the law.”

The safer path is to use messages you legitimately received or sent, and to ask the court for anything else. In a custody or divorce case, attorneys can use discovery and subpoenas to obtain records through proper channels. Evidence gathered lawfully is far more useful than evidence that creates a new legal problem for the parent who collected it.

What If You Think Your Phone Is Being Monitored?

Signs of stalkerware can include fast battery drain, unexplained data use, a phone that overheats or shuts down unexpectedly, and an ex who knows where you have been or what you have said privately. Before removing anything, think about safety and preserving evidence.

The Federal Trade Commission warns that removing monitoring software can alert the person who installed it and may escalate abusive behavior. It recommends using a separate or borrowed phone to seek help, documenting what is happening before making changes, and considering a new phone with accounts the other person cannot access.

If the other parent is monitoring your phone, that conduct may be relevant to custody and may support a family offense petition. Speak with our NYC child custody attorneys about how to document it and what steps to take.

Do Social Media Posts and Emails Count Too?

Yes. Emails, social media posts, direct messages, photos, and videos follow the same basic rules as text messages. They must be relevant and authenticated. Public posts about parties, drinking, new partners, travel, or the custody case itself frequently appear as exhibits in custody hearings.

During a custody case, assume that anything you post can be seen by the other parent, the attorney for the child, a forensic custody evaluator, and the judge. Avoid posting about the case, the other parent, or the children’s private lives. Do not delete existing posts that may be relevant without talking to counsel first, because deleting evidence can create its own problems.

How Do Our NYC Child Custody Attorneys Use Digital Evidence?

Our NYC child custody attorneys treat digital evidence as part of the trial record from day one. That means preserving messages early, organizing them into a clear timeline, authenticating them properly, obtaining missing records through discovery, and presenting them in a way that helps the judge see the full pattern.

• Early preservation. Our child custody lawyers help clients capture and back up messages before anything is lost.
• Timeline building. Our NYC custody attorneys organize messages alongside school records, medical records, and parenting logs so the pattern is easy to follow.
• Discovery and subpoenas. Our family law attorneys request records from the other side and from third parties when the full picture is not on the client’s phone.
• Communication guidance. Our NYC child custody lawyers help clients adjust how they communicate with the other parent while the case is pending.
• Hearing and trial presentation. Our custody attorneys authenticate exhibits, prepare clients to testify about them, and challenge unreliable or unlawfully obtained evidence from the other side.
