Its a hard question to answer because first of all  Bitcoin replicates many of the formal aspects of real estate transactions.Bitcoin transactions have features that closely resemble grantor names,grantee names,legal descriptions,and signatures found in real property deeds.While these "bitcoin deeds" may eb interesting,they are not profound!Which means Bitcoin goes beyond creating simple digital deeds,however,and replicates institutional aspects of real estate in particular recordation and title assurance (as in your case).When more than one grantor executes more than deed covering the same property,recordation acts determine which grantee wins.
