If you are represented by an attorney - talk to them. Depending on what you did in your chapter 13 there are serious issues involved in converting your case: vehicles, house, taxes, child support, etc.. If you are not represented see my warning above. As far as how to convert - in Arizona you file a notice with the court. I don't know where you live so cannot predict the procedure you need to take. See if there is a self-help center at your Bankruptcy Court. If not, perhaps a volunteer lawyer group.
