Since the letter had no legal force, there is nothing to nullify. It appears that you are being harassed, and I suggest that you contact a local attorney. You can find one in Oklahoma City via AVVO search or in local ads. Take the letter along, as well as the details as to this stalker. It may be that your attorney will suggest you file criminal charges, but CONSULT FIRST.
We do not have a client/attorney relationship until you make an appointment, we discuss your case face to face, I accept a retainer, and we explictly agree to enter into representation.
