AH, different state laws. In Mich9igan, where this title would be from, there is no requirement for a notarized title. If an owner has a title with no bank lein on it, it is considered a "clear title". When he sells it to someone, then he signs off of it and the new ownder simple fills in his own info and signs whenever he wants and then takes it to the Sec of State office. No notarizing needed at all. In fact, if you have a title that was signed off by the previous owner, you don't even have to sign it and title it yourself if you don't intend to register it for plates, though technically you are suposed to.
Say you bought it just to resell it real quick. The previous owner signs off the title, you take the title and sell the bike to someone else the next day and you just give them the title signed off of by the previous owner without ever having re-titled it in your name. As long as that title is clear ( no leins) and is signed off of by the previous owner, it is a good title. The party that yuo resold it to would just fill in their info and take it to the SoS office. Plain and simple.
SO in this case, since it is a Michigan title you are talking about, it is a clear and good title. That's why I wasn't familar with your term, "open title". In fact you buy any bike from MI and that is what you are going to get
