You can certainly file a lawsuit for trespassing or nuisance and ask the court for a restraining order that way or, if you can convince a court that his behavior has escalated to the legal level of threatening or harrassment, you can ask for a personal protection order. To fully understand your options, you should contact a local attorney with experience in both criminal law and real property law. Most general practioners can help you in these areas. The worst thing you can do is take the law into your own hands. Good Luck.
So there is no misunderstanding, my answer to your question does not establish an attorney/client relationship with me or my firm and such a relationship will not be established unless and until you personally retain me or my firm to represent you.
