When your narcissist ex turns to social media to broadcast lies, it can feel like a personal and public ambush. The emotional toll is heavy, but the legal implications can also be significant.


Many clients ask, "Can I use these posts in court?"

The answer is: yes, but with careful handling.


Social media content can absolutely be used as evidence in family court. However, you must approach it strategically. Start by documenting everything your ex posts that contains false accusations, character attacks, or anything that pertains to parenting. Take clear screenshots, include timestamps, and preserve the original posts in case they are deleted later.


First, understand the nature of what they're posting. Is it defamation? Harassment? Emotional manipulation? Courts are increasingly receptive to digital evidence, especially when it reveals a pattern of alienation, bullying, or defamation that affects the child or co-parenting dynamic.


You must document everything. Take screenshots with timestamps. Use metadata where possible. Avoid engaging publicly, as narcissists thrive on reactions and can twist your responses.


Next, frame the content through the lens of parenting. Judges care about what affects the child’s best interest. Show how the social media behavior endangers your co-parenting relationship, undermines your authority, or emotionally harms the child.


Use the evidence strategically. Don’t make your case about "who looks worse online." Focus on impact. If needed, file motions asking for restrictions on online conduct, or request protective orders when the content escalates.


These posts can demonstrate patterns of harassment, defamation, or alienation. If your ex is consistently posting harmful or untrue content that affects your parenting or relationship with your child, this can be highly relevant in custody disputes.


But be cautious. Judges aren’t interested in petty back-and-forth or one-off outbursts. What matters is showing how this behavior impacts the best interest of your child. Frame your evidence around that principle.


For instance, if your child has started questioning your character based on what they saw online, or if the co-parenting dynamic has become toxic due to online defamation, those facts matter. Courts prioritize the child’s emotional and psychological safety above all.


In addition to documentation, consider filing a motion to limit or prohibit social media postings related to the case or your child. Many jurisdictions now recognize the harm that can come from online behavior and may grant protective orders or include restrictions in parenting plans.


Resist the urge to respond publicly. Narcissists thrive on drama and reaction. Your restraint will serve you well in court and keep the focus where it belongs—on your child's wellbeing. It can also help to gather character references and evidence of your parenting record, including messages, school involvement, or therapy notes. This allows the judge to see your consistent, calm presence against the narcissist's inflammatory conduct.


Your attorney can guide you in submitting social media evidence properly. Courts typically want to see authenticity—so preserve metadata when possible and avoid editing screenshots.

Lastly, remember this: what feels humiliating online can become powerful leverage in court. Document carefully. Stay composed. And make the evidence work for you.
