To make sure, I would call an Ohio title office (Maybe Eaton, OH as they are close to the border). I'm thinking that you can just sign it in front of ANY notary. Take the title into a bank, fill out your info and sign it in front of the Notary, then give it to the buyer with a bill of sale (" I sold scooter VIN#....... to John Doe on 2/8/12 for $100"). He'll fill out his own info on the OH title before he takes it in for the xfer. Make sure you both agree on the selling price stated on the title and bill of sale. I've had the DMV call me (and the buyer) years later to verify the selling price. I wouldn't worry about the Indiana piece of the puzzle. Its titled in OH, and he's keeping it in OH. If you give him an Indiana title, he'll have to take it for an out-of-state inspection ($$$ and hassle), etc. Ohio thinks its still in Ohio, and it'll be kept in OH. No reason to involve Indiana. Has your driving deteriorated yet? I HATE getting behind Indiana-plated cars.
