One of the very first steps to take in any legal dispute is to consult with your attorney about the best practices for handling communications and information regarding the dispute. It can be tempting to immediately pick up the phone and start talking, texting, or emailing others when you learn about a lawsuit or the prospect of one. This can lead to trouble.
In litigation an adversary can ask for and receive copies of all unprivileged communications and information relevant to the legal dispute. This could include discovery of communications (both verbal and written) with friends or colleagues, business associates, suppliers, employees and customers. So, it is important to be careful about creating communications or information that concern the legal dispute or the adversary.
What may seem like a reasonable or harmless communication to you about the dispute will need to be preserved, will be subject to discovery, and it could be used against you in unanticipated ways. This is certainly true when it comes to expressing opinions about the dispute or your adversary.
When it comes to such opinions, reserve expression of them to verbal communications had with your attorney in confidence. Attorney-client communications are privileged and generally not subject to discovery by an adversary. However, to preserve the protection of the privilege you must keep all such communications with your attorney confidential.
