The less information is floating out in the public sphere, the more control you and your attorneys have about your case. In any successful Personal Injury case, it’s important to share information to convey your story, but this should only be done in a controlled manner and under your attorney’s supervision.
It’s common practice for defense attorneys and insurance companies to due a cursory search online with your name, email address, home address, telephone number, or any other identifiable information they have available to them. This will very likely lead them to your social media profile(s). You may be forced to disclose your private posts if your case is filed with the court, where formal discovery proceedings are allowed.
