I've heard OfficeMax has a kit for about $70. Eventually you will need an attourney, but only for filing fees, if you correctly fill out the paperwork, and you may not end up needing one. I wish I knew a website. I know in Chicago there are billboards advertising divorces for under $300. I have a friend who did it, and was very happy with how fast and easy it was. Maybe enter "cheap divorces in Indiana", in the search engine and see what you get. Good Luck. Worst case scenerio, is you each retain a lawyer and since it's an uncontested divorce you pay minimal fees.
Good luck,
let us know how it goes.
