It is settled law that a Certificate of Occupancy regularity issued by competent authority raises the presumption that the holder is the owner in exclusive possession of the land in respect thereof. The presumption is however rebuttable. But there is no evidence from the Appellant to rebut the presumption. As a matter of fact, the Appellants did not attack the Certificate of Occupancy.
