Fkent,
Note that pnoid said he bought it as a stolen vehicle. I took that to assume that it is already titled as a previously-stolen vehicle. That's the assumption I based my comments on, that and the fact that pnoid was talking about a conversation with the dealer. If it's already titled as previously stolen (pnoid, is it?) then I can't see why "by law", "any law" he would be required to VOLUNTEER that information again, in a conversation.
If asked, yes, he shouldn't lie. If signing over the title there is a checkbox to indicate previously stolen status, then he should check it, and sign over the title.
But in conversation, if not asked, should he SAY anything?...That seemed to be his question.
Again, unless someone shows me a law SPECIFICALLY about having to volunteer such information in conversation, then I will stand by what I said.
Now, if pnoid asked: When signing over the title do I have to indicate it is previously stolen? Then I would ask if on the title transfer documentation there is a place to report such things. He didn't specifically ask that question, nor indicate if the vehicle is already titled as previously stolen.
