That Instagram Post Could Cost You Custody. Here's What Courts Actually Do With Social Media.
According to the American Academy of Matrimonial Lawyers, over 80% of divorce attorneys have used social media evidence in their cases. Facebook posts, Instagram stories, dating app profiles, Venmo transactions, and even LinkedIn updates have all been admitted as evidence in divorce proceedings. What you post — and what your spouse posts — can dramatically affect custody, asset division, and support.

Get Guidance NowWhat Social Media Evidence IS Admissible in Court
Courts generally treat social media content the same way they treat other documentary evidence. If it's relevant and properly authenticated, it's likely admissible. Here's what courts regularly accept:
Public posts and photos
Anything you post publicly on Facebook, Instagram, X (Twitter), TikTok, or any other platform is fair game. A photo of you partying when you claimed to be too sick to work, or a vacation post when you said you couldn't afford child support — courts see these regularly.
Direct messages (DMs) and private messages
Messages sent to or received by your spouse are admissible because they're a party to the conversation. Messages obtained from the other person in the conversation (a friend, affair partner) may also be admissible if that person voluntarily provides them.
Dating app profiles
Active profiles on Tinder, Bumble, Hinge, or other dating apps can be evidence of adultery (relevant in fault states), proof that a relationship has ended (useful for separation date disputes), or evidence of lifestyle inconsistent with claimed finances.
Check-ins and location data
Facebook check-ins, Instagram location tags, and geotagged photos can prove where a person was at a specific time — contradicting testimony about whereabouts, proving meetings with affair partners, or showing a parent wasn't where they said they'd be during custody time.
Financial posts and transactions
Venmo transactions (which are public by default), posts showing expensive purchases, vacation photos, or social media marketplace listings can all contradict claims of financial hardship or hidden income.
Comments, likes, and interactions
Even passive engagement can be relevant. Liking inappropriate content, commenting on an affair partner's posts, or interactions that suggest a closer relationship than admitted can all be presented to the court.
What Is NOT Admissible (and Can Get You in Trouble)
Not all social media evidence is fair game. Obtaining evidence improperly can not only get it excluded — it can result in sanctions against you or even criminal charges:
- ✗Hacking into your spouse's accounts — Accessing your spouse's social media, email, or other accounts without permission violates federal law (the Computer Fraud and Abuse Act) and state wiretapping laws. Evidence obtained this way is typically inadmissible AND can result in criminal prosecution.
- ✗Using a fake profile to gain access — Creating a fake account to “friend” your spouse and view private content is considered deceptive. Many courts will exclude this evidence and some states consider it a form of harassment.
- ✗Illegally recorded conversations — Recording phone calls or video chats without consent (in two-party consent states like California, Florida, and Illinois) is illegal. Screenshots of text conversations you're part of are different from recorded calls.
- ✗Unverified or altered screenshots — Screenshots that can't be authenticated or appear to have been altered may be excluded. Opposing counsel will challenge the authenticity of any evidence you present.
- ✗Hearsay content — A post by a third party saying “I saw your spouse at a bar last night” is generally hearsay and may be excluded unless the third party testifies. Your spouse's own posts, however, are admissions by a party-opponent and are not hearsay.
How Social Media Affects Custody Decisions
Custody is where social media evidence has the most devastating impact. Judges make custody decisions based on the best interests of the child, and social media provides a window into a parent's real behavior:
Evidence of substance abuse
Photos or posts showing excessive drinking, drug use, or partying — especially during parenting time — directly impact custody. A parent who posts photos drinking heavily on a weeknight when they have the children is giving the other side powerful evidence.
Parental fitness concerns
Posts showing reckless behavior, violent language, association with dangerous people, or neglect of parental duties can all be used to argue a parent is unfit. Even “venting” posts expressing hatred toward the other parent or frustration with the children can be harmful.
Badmouthing the other parent
Courts take a very dim view of parents who publicly disparage the other parent on social media. This behavior suggests an inability to co-parent and can be seen as parental alienation — a factor that can actually cause a court to reduce your custody time.
Contradicting testimony
Telling the court you're a dedicated, stay-at-home parent while your Instagram shows you traveling constantly or out every weekend destroys your credibility. Judges have very long memories for litigants who mislead the court.
Social Media and Hidden Income or Assets
One of the most effective uses of social media in divorce is exposing financial dishonesty. People who claim poverty in court often can't resist showing off on social media:
- ✓Lifestyle inconsistencies — Claiming you can't afford child support while posting photos from a luxury vacation or with a new car is a gift to the opposing attorney.
- ✓Undisclosed businesses — LinkedIn profiles, business Facebook pages, or posts about business deals can reveal income sources not disclosed in financial declarations.
- ✓Venmo and Cash App — Venmo transactions are public by default. Payments labeled “rent,” large transfers, or frequent payments from unknown sources can indicate hidden income or assets.
- ✓Marketplace sales — Facebook Marketplace, eBay, and Poshmark activity can show unreported income from selling assets or running a side business.
- ✓New partner's lifestyle — If your spouse claims financial hardship but their new partner posts about expensive gifts, trips, or a shared luxurious lifestyle, this can suggest undisclosed income.
Protecting Yourself: The Social Media Rules During Divorce
The best advice most divorce attorneys give their clients about social media is simple: assume everything you post will be read by a judge. Here are specific guidelines:
Do NOT delete posts or accounts
This is the most critical rule. Once litigation has started (or is reasonably anticipated), deleting social media content constitutes spoliation of evidence. Courts can impose severe sanctions, including adverse inference (the court assumes the deleted content was damaging). Even deactivating an account can be seen as destruction of evidence.
Tighten your privacy settings
Set all accounts to the maximum privacy level. Remove your spouse and their family and friends from your connections. Review who can see your posts, photos, and check-ins. Be aware that privacy settings are not foolproof — mutual friends can still screenshot and share your content.
Stop posting about your personal life
No photos of dates, parties, vacations, or expensive purchases. No venting about your spouse, the divorce, or the legal process. No cryptic “subtweets” or vague posts that could be interpreted negatively. If you must post, stick to completely neutral content.
Ask friends and family not to tag you
Even if you're careful, a friend tagging you in a photo at a bar or a family member posting about your new relationship can undermine your case. Let your inner circle know you're going through a divorce and ask them to keep you off social media.
Preserve your spouse's social media
If your spouse's social media contains relevant evidence, preserve it immediately. Take screenshots that include the URL, date, and time. Better yet, use tools that capture metadata or have your attorney issue a preservation letter to your spouse requiring them not to delete content.
Screenshots, Metadata, and Authentication
To use social media evidence in court, you need to authenticate it — prove that it is what you say it is and hasn't been altered. Here's how to do it right:
- ✓Full-page screenshots — Capture the entire page, not just the post. Include the URL bar, the poster's profile name, the date and time of the post, and any engagement (likes, comments).
- ✓Multiple capture methods — Take screenshots on your device AND use a web archiving service like the Wayback Machine (archive.org) or a legal preservation tool. This provides independent verification.
- ✓Preserve metadata — Photos posted on social media often contain EXIF data showing when and where the photo was taken. This data can prove a photo was taken on a specific date at a specific location.
- ✓Chain of custody — Document when you captured the evidence, from where, and store it securely. If questioned, you need to show the evidence hasn't been tampered with.
- ✓Witness affidavit — If someone else saw the post, their testimony can help authenticate the evidence. This is especially useful for content that was later deleted (before litigation started).
