Unfortunately, no relevant information is found.
Anyway, it doesn't matter, better continue with my doubts. In my case, if my car were stolen and not only the plates, I would need a title replacement?
I mean, like the title was lost because it was inside the car?
Well, yeah. If that were the case, certainly you should apply for a replacement title as soon as possible, to prevent any real damage. You can check Replace a Title Certificate section for more information.
