I agree with the learned trial Judge that Exhibit 3 is an instrument within the meaning of section 2 of the Land Instrument Registration Law and that having regard to the mandatory provisions of section 15 of the said law no registrable instrument which has not been registered should be given in evidence. But it was probably too wide a statement for him to have concluded that “no title” could be based on Exhibit 3. Certainly not a legal title but equitable title or interest, yes. In the case of Okoye v. Dumez Nigeria Ltd & Anor (1985) 1 NWLR (Pt.4) 783: (1985) 6 S.C. 3 Bello. J.S.C. (as he then was) delivering the lead judgment said on page 12 thus: “It is trite law that where a purchaser of land or a lessee is in possession of the land by virtue of a registrable instrument which has not been registered and has paid the purchase money or the rent to the vendor or the lessor, then in either case the purchaser or the lessee has acquired an equitable interest in the land which is as good as legal estate and this equitable interest can only be defeated by a purchaser of the land for value without notice of the prior equity. A registrable instrument which has not been registered is admissible to prove such equitable interest and to prove payment of purchase money or rent: Savage v. Sarrough (1937) 13 NLR 141: Ogunbambi v. Abowab (1951) 13 WACA 222: Fakoya v. St, Paul’ s Church, Shagamu (1966) 1 All NLR 74: Oni v. Arimoro (1973) 3 S.C. 163; Bucknor-Maclean v. Inlaks ( 1980) 8-11 S.C. 1 and Obijuru v. Ozims S.C. 48/1984 delivered on 4th April 1985 unreported yet. It follows from the foregoing that the 1st respondent’s lease under Exhibits E and F was as good as if the instruments had been registered.”
