> He is charged with notice of every fact shown by the record and is presumed to know every fact shown by the record and is presumed to know every fact which an examination of the record would have disclosed
> Since it is the act of registration which transfers ownership of the land sold, it has been held that a subsequent claimant cannot claim a better right over the land which had been previously registered in the name of another.
