Yes, you can FAX or MAIL it to the Attorney Generals. But like Step 1 shows, if you decide to fax or mail, then you need to complete the affidavit of service form which needs to be sworn in and given to a court clerk. If you go in person and get the stamp, then no affidavit of service needs to be completed.
At trial, you would argue that the law allows one to make motions (as in your motion to stay your trial) without notice to anyone. If it gets this far at trial, expect difficulty in getting the Justice to accept that.
