I second jghilino's comment, You don't have to sign title nor transfer it into your name, and all my yards here in Indiana, all they do is check the title to the VIN on the car being hauled in. If you have title- it is like having the keys so to speak- If you want to be doubly safe- run a VIN check, print it out and bring it in with you to the yard with title, that way you can show it is not stolen, you have the vehicle, presumably the key, and the title.
