ok a couple months ago i sold a car that was still register to the previous owner the guy i sold it to just signed as the buyer and had no problems. also ounce i bought a car and the owner signed in the buyers box by mistake and i didn't realize it till i got home i singed as the seller and the lady at the dmv didn't say anything about it. i have also sign for the buyer one time in print and then signed my name in the buyers box and the lady didn't say anything. i guess what I'm trying to say is that what they don't know benefits you if the previous owner signed in the right box and you sign the buyers box i think you should be fine just scratch the other signature of and say that the owner was signing in the wrong place and he scratched it off him self just make sure the color ink of the pens your using match and be courteous to the lady's at the dmv, it helps, and i think you will have your new title without all the hassle of a long process and having to pay to much to get it to your name. at least that's how it has worked out for me in the past.
