In determining whether any given transaction is in the nature of a mortgage, equity looks at the substance of the matter and not merely at the form. – Iguh JSC. Ejikeme v. Okonkwo (1994)
A MORTGAGEE HAS A POWER OF SALE AS OF RIGHT IN THIS INSTANCE
A mortgagee, unless where a contrary intention is shown, has a power of sale provided: (a) the mortgage was made by deed; and (b) the mortgage money is due, that is the legal date for redemption has passed. Where the money is payable by installments, the power of sale arises as soon as any installment is in arrears.
