Legal Question in Civil Litigation in Indiana

Re: stopping an ex affair from ruining a marriage

Probably not. (Of course, blackmail is a crime, and if the threat is coupled with a demand for money, you might want to call the police.)In many states the disclosure of private information is something you can sue for if it is sensitive enough and causes harm. However, in Indiana, if the information is true, you cannot sue. There may be other avenues you could try, so go see an attorney about this.

Good luck.
