I must note right away, that the admissibility or otherwise of an unregistered registerable instrument depends on the purpose for which it is being sought to be admitted. – Nweze JSC. Abdullahi v. Adetutu (2019)
THREE MAIN CRITERIA FOR ADMISSIBILITY OF A DOCUMENT
A good starting point is to state the three main criteria that govern the admissibility of a document in evidence, namely:- (1) Is the document pleaded? (2) Is it relevant to the inquiry being tried by the court? and (3) Is it admissible in law? See Okonji v. Njokanma (1999) 11 – 12 SCNJ 259 @ 273 where Achike JSC stated thus: “The position of the law in relation to the question of admissibility of a document in evidence is that admissibility is one thing while the probative value that may be placed thereon is another. Generally, three main criteria govern the admissibility of a document in evidence, namely: (1) is the document pleaded? (2) is it relevant to the inquiry being tried by the court? and (3) is it admissible in law?”
