You don’t need to hire a detective if you are trying to establish your spouse’s infidelity. Too often you can simply use social media including Facebook, Twitter, MySpace, Match.com, eHarmony, etc., to obtain information about your spouse’s internet relationships. When you choose to “friend” or “follow” or when you “write on a wall” or when you list your significant other as a “friend” on your profile, the impact on your marriage can be great. Facebook, Twitter, MySpace cannot be erased. Just because you press a button that says delete does not mean the information does not leave a permanent digital trail. Information posted on Facebook is often used as evidence in divorces. For example, if a separated man on Facebook in his efforts to imbelish his profile indicates that he earns $100,000 when he does not, that information can be used against the husband in the divorce trial. Inappropriate pictures also are fuel for placement and custody cases. The bottom line is be careful what you post online.
