For a sale under customary law, such as the sale to the plaintiff in 1965, this Court has in A.O. Odufuye v. Jacob Adeoye Fatoke (1977) 4 SC. 11, accepted the proposition of law that where the purchaser fails to pay the full purchase price there is no valid sale. This must be so, for to constitute a valid sale of land under customary law, three essential ingredients are required, viz: (i) Payment of the purchase price (ii) Purchaser is let into possession by the vendor (iii) In the presence of witnesses See: Aboyade Cole v. S.R.. Folami (1956) SCNLR 180; (1956) 1 FSC 66; Akingbade v. Elemosho (1964) 1 All NLR 154; Ogunbambi v. Abowaba, 13 WACA 222, 225. It follows, therefore, that where the purchase price is not fully paid there can be no valid sale, notwithstanding that the purchaser is in possession.
