If you do it just get the BIS notarized so he can't try to say it's fake. Also, find out what is his reasoning why he can't give you the signed title and you just hold it until November? If he gives you the title and you don't transfer it into your name before then it won't affect anything he has going on with it right now. If you can get him to do that you can be cool and just hold the title or since he seems like he's fuckin you around get it and go transfer it anyway. Once you have the signed title it's yours whether you get it transferred into your name or not.
