Daniel Igwu Uche v. Jonah Eke and 2 Ors., the Supreme Court per Belgore JSC (as he then was and now CJN) had this to say at pages 6 to 7: “Any grant of land whether private or by statutory right of occupancy evidenced by a certificate of occupancy will be mere piece of paper not worth anything if the root of title to make the conveyance is not vested in the vendor. If this is not so, all a person has to do is to go to the land office of the government and obtain a right of occupancy in respect of land of a family who may not know that their land has been given to a complete stranger.”
POSITION OF THE LAW WHERE TWO OR MORE PERSONS CLAIM A RIGHT OF OCCUPANCY OVER THE SAME LAND
“The law has been settled for long that where two or more persons claim title to land or a right of occupancy over the same land, the first in time takes priority as it is stronger in law. The latter grantee is deemed not to have been granted any title or right of occupancy. A grantor of title or right of occupancy cannot give title or right of occupancy to two persons, one must be valid, the other invalid. The law is trite one cannot grant title over a parcel of land and still be in legal position to grant such title to another. He would have no such title to grant to the latter grantee under the doctrine of “nemo dat quad non habet”. See FBB Ind. Ltd. v. Mutunci Co. (Nig.) Ltd. (2012) 6 NWLR (Pt. 1297) P. 487 @ 524; Omiyale v. Macaulay (2007) 7 NWLR (Pt. 1141) P. 597; Ibrahim v. Osunde (2009) 6 NWLR (Pt. 1137) P. 382; Ashiru v.
