No Secrets in Cyberspace: Admissibility of Texts, Emails, and Social Media Posts in the Courtroom


What to Know about Digital Messaging, Social Media, Investigations, and Litigation

I recently saw a meme on social media that said something like “Dance Like No One is Watching, But Text, Email and Post Like it Will be Read in Court One Day.”  Wise advice from the Land of Meme.

Whether the matter is a criminal investigation, criminal prosecution, civil action, and/or family law case, digital communications, texts, emails and social media posts are fertile and increasingly common sources of evidence in investigations and litigation.

Digital communications such as texts, emails, and social media posts can be introduced into evidence through simple circumstantial evidence.  New Jersey Rules of Evidence 901 establishes that “[t]he requirement of authentication or identification as a condition precedent to admissibility is satisfied by evidence sufficient to support a finding that the matter is what its proponent claims.” As one New Jersey Appellate Division panel confirmed, the standard for admissibility is fairly low and does not need “certainty” or “conclusive proof.”  A basic (“prima facie”) showing that the posting is authentic is all that is required.

Fake text messagePeople sometimes drink and type.  People sometimes get angry and type.  People sometimes get “high” and type. Whether the communication is in a text, email or a social media post, stupid, angry, or impulsive rants are creating a record, potential evidence, that may one day become a source of embarrassment, a rejection for employment, worse yet, become damaging evidence in a court room.

It is remarkable as to the extent people willingly and recklessly surrender their privacy to others through the internet without a second thought.  People can text, email, and/or post personal, sensitive, embarrassing and sometimes incriminating information about themselves, their families, their friends, and believe it or not, even their co-conspirators.  

Texting, emailing or posting photographs and comments about incidents that involve potential civil lawsuits, family law proceedings, investigations, and/or criminal charges is simply foolish.  Sadly, people voluntarily disclose the most personal and/or embarrassing information through digital messaging platforms and social media sites, and in the process generate a digital trail that makes it easy to retrieve such information for use in a court room.

It is not unusual for angry, reckless texts, emails, and/or postings to occur in incidents involving parties, clubs or other venues where drug use or allegations of physical or sexual assault arise. The posting of photos or videos of people smoking marijuana or being obviously intoxicated at a party or bar may seem funny to some, but may be disastrous if there is a related criminal investigation, a custody dispute, pending employment application,  or if there is civil litigation anticipated or pending.  It may sound obvious, but people disregard the obvious risks and text, email, and post at their peril.

In any criminal investigation, potential or pending civil action, or family part matter, one of the first places an adversary checks for information is the history of digital communications, texts, emails, and social media profiles and posts.  Simply put, the digital profile of a person is an invaluable source for the collection of evidence.

Remember that digital records may one day be read out loud, for the world to hear, in court.  While you may dance like no one is watching, your digital profile is forever.
