An agency is a fiduciary relationship said to be created when a person (principal) gives authority to another (agent) to act on his behalf and the agent accepts to act on the authority. The authority may be express or implied. This relationship is usually not determined by the terminology used by the parties to describe their relationship but on the nature of their agreement and the circumstances of the relationship between parties. See Bayero v. Mainasara and Sons Ltd (2006) LPELR-7587 CA; (2006) 8 NWLR (Pt. 982) Pg. 391; Upkanah v. Ayaya (2010) LPELR-8590 (CA). An agency can be created by any of the following; 1. Agreement whether formal or not between the parties. 2. Ratification by the principal of the acts done on his behalf. 3. Operation of law under the doctrine of necessity. See Niger Progress Ltd v. N.E.L. Corp (1989) NWLR (Pt. 107) 68; (1989) LPELR-1996 (SC) 33; Edem v. Canon Balls Ltd and Anor (2005) 12 NWLR (Pt. 938) 27; (2005) LPELR-1007 (SC); (2005) 6 S.C (Pt. II) 16; Ukpanah v. Ayaya (Supra).
