Most developed contries have digitized their deed system, so I am not sure how you can con someone out of their deed.
Also, back when we did use physical deeds, there generally was owner’s copy and land office’s copy, and on the back of the deed would be the transfer history.
So to con someone out of their deed, you would not only need to get the owner’s deed, but you would also have to get your name added to the land office’s copy.
