You both go to the Ampur where you were married, both taking your marriage paper with you. Tell them you want a divorce, both fill out a paper, the clerk will help you. If there are no children or assets and she doesn't want monthly payments ( hopefully she wants the divorce too ) you see the big guy, he'll talk to you a bit sign off. They'll give you each a divorce paper and you're on your merry way. takes all of an hour, no lawyer need.
