Difficulty: Moderately Challenging
Step1
Your first step is to see if you can remedy the situation without resorting to charges or legal means. Although it can be nerve-wracking, it might help to try an arrangement with those who are threatening blackmail. A compromise is sometimes possible.
Step2
If compromise doesn't work, blackmailers occasionally respond to some kind of hardball response. If you have information on the blackmailers, it's possible to reach some kind of stalemate that will de-escalate the situation.
Step3
Think about damage control. If you can somehow erase evidence of whatever the blackmailers are threatening to expose, the situation will be somewhat resolved. However, be fully cognizant of legality, some types of covering up activities are legal, and some are not. This depends mainly on the type of behavior that blackmailers are threatening to expose.
Step4
Get lawyered up. If you are going to pursue blackmail charges, your lawyer can best instruct you on how to go about it. You will want to have a thorough understanding of case precedents. Some cases of blackmail are prosecutable and some are not.
Step5
Contact a private investigator. Besides lawyers, private investigators also have knowledge of the ins and outs of blackmail situations, and on how to react to threats legally and maybe without entering the courtroom.
