Search the forums. Title issues have been discussed quite often. But, yeah, it varies pretty widely state to state.
Some states, like FL, would require ALL of 'em (the guy who's name is on the title PLUS whoever's signatures are on there) to come in and two ALL the transfers - A to B, B to C, C to you... And pay for it each time. In other words, you'd be screwed.
Other states don't have any provisions AT ALL.
Other states are pretty lenient or have non-burdensome requirements.
Good luck, but anymore, for me here in FL, non-titled bikes are only bought if I need the parts...
