Re: Title help!!!
Not sure what IN needs to title the boat. I believe (though I've never done it) the seller here in TN can get a document (not sure what it's called) in lieu of a title for you as an out of state purchaser. But I'm 90% sure that has to happen through the seller (as you're not a resident and haven't registered the boat here).
Though, check with Indiana and see if they'll accept a bill of sale to title.
There might be a way for you to register the boat in TN (our laws require a TN registration even for non-residents if the boat runs mostly on TN waters). If you can do that, then you might be able to establish ownership to satisfy IN to register up there. Again, have never done that myself so I'm not sure how it would practically work.
