The common law doctrine of uberrimae fidei is pivotal to all contracts of insurance. It imposes a duty on the parties to act towards each other with utmost good faith by disclosing all material facts and not misrepresenting any fact, either before the contract is formed or while the contract subsists. This article examines the doctrine and its statutory reforms in Nigeria and the United Kingdom. It argues that, before the statutory interventions, the iniquitous doctrine was a potent weapon, most often used by insurers to defeat just and legitimate claims by an insured. Although the legislation has brought some measure of relief to the insured in these jurisdictions, the article concludes that there are still some grey areas in the Nigerian law that need to be addressed to further the cause of justice between the contracting parties.
