It has to be stressed however that the term delivery, in law, is not synonymous with the physical exchange of signed and sealed documents between the parties thereto. It does not also mean the handling over of a document to the other side. It does mean and has been judicially interpreted to connote an act done so as to evince an intention to be bound. Even though the possession of such deed still remains with the maker, or his solicitor, he is bound by it if he has had it delivered in law by doing some unequivocal act whether by words or action evincing an intention to be bound. – Iguh JSC. Awojugbagbe v. Chinukwe (1995)
EXTRINSIC EVIDENCE CANNOT VARY A DEED
It was common ground that the relationship between the plaintiff and the 1st defendant is contractual and governed by exhibit B, the Deed of Legal Mortgage. That being so, extrinsic evidence will generally not be acceptable to vary the terms agreed upon (see for example U.B.N. v. Ozigi (1994) 3 NWLR (Pt. 333) 385). – Kutigi JSC. Okonkwo v. Cooperative Bank (2003)
