The onus or burden of proof is merely an onus to prove or establish an issue. There cannot be a burden of proof where there are no issues in dispute between the parties, and to discover where the burden lies in any given case, the court has bounden duty to critically look at the pleadings. The general rule is that, it is the plaintiff who seeks a decree of declaration of title that has the onus of proof: Onobruchere v. Esegine (1986) 1 NWLR (Pt. 19) 799; Kwamina Kuma v. Kofi Kuma (1936) 5 WACA 4; Kodilinye v. Mbanefo Odu (1935) 2 WACA 336 at 337; Ayitey Cobblah v. Tettey Gbeke (1947) 12 WACA 294 at 295; Anachuma Nwakaf or and Ors Nwankwo Udegbe and Ors (1963) 1 All NLR 107; Nwankwo Udegbe and Ors v. Anachuma Nwokafor and Ors (P.C) (1963) 1 All NLR 417; Mogaji and Ors v. Odofin and Anor (1978) 4 SC 91; Bello v. Eweka (198 1) 1 SC 101 at 117-120. The norm in civil cases is that the plaintiff starts the process of testimony first and his witnesses if any, thereafter, the defendant proffers his evidence in defence.
