Are there laws that protect a spouse harassment after divorce and what are those?

If your son is 21 he is an adult and the might be little you can do against your ex.

First things first. Check with your divorce lawyer. If you did not have one, consult one now. You'll need to see the precise language of the divorce decree and any agreements or other documents which were included with it. You might find that he has violated part of a court order, in which case he could be held in contempt of court. You might also decide to try to resolve matters outside of court: it can be far less embittering, and certainly far less expensive. It's no clear what the role of your 21-year old son is in this. Is he participating in the harassment, or is he a victim of it? If he is a victim, he is old enough so that you may not fight his battles for him. Consult a skilled family lawyer. Good Luck.

If your so. Is 21 the court would have no jurisdiction over any of you.

Your son is an adult. If he feels harassed, he and not you needs to address it. It has nothing to do with the divorce. You don't say who is blocking communication, but none is required among any of you since all of you are adults.

If you believe you are being harassed, you can file for an injunction. You will have to convince the Court that it is harassment before the injunction will be issued. Go to the Court Clerk to get your paperwork. Good luck.

Post divorce harassment is potentially a crime, and it can be potentially enjoined. Your child is now an adult and therefore able to make their own mind up as to who is correct or not. It is sad, but commonly children are brought into and placed in the middle of divorcing parents. I would suggest you consult with a family law attorney.
