How do I disown my son who has stolen from me, harassed and stalked me, hired others to steal and harass me?

You should consult with an experienced estate planning attorney in your area. He or she can help you to prepare your will, and power of attorney documents. In the will you must specifically state that it is your intent to leave no property or money to this particular child.

Don't give him anything in your will. That's what disowning means.

What good will it do? You don't have to give him anything and in your will specifically state that he gets nothing. Call the police regarding the thefts and go to court and get a protective order against him.
