In the United States, a person can do pretty much anything in the legal system by representing themselves. In the legal word, this is known as pro se representation ("pro se" is Latin for "for oneself"). If you feel comfortable doing this procedure, then it's your right to go ahead and file it. Don't count on the judges or the State to give you any leeway because you are not an attorney. If they can oppose your motion or claim that you haven't properly noticed them, then they will. This can mean a lot of wasted time down at the courthouse that you might save by hiring an attorney to file this petition for you.
Ultimately, this decision is up to you. Good luck.
