An Analytical Study of the Doctrine of Unconscionability in Nigerian Contract Law and Its Application to Standard Form Contracts

Unconscionability as a doctrine invalidating contracts obtained through inequality of bargaining power, procedural unfairness, or substantive imbalance has been received into Nigerian law through equity, yet its development in Nigerian judicial decisions and its application to standard form contracts including insurance policies, consumer credit agreements, and franchise agreements remain analytically underdeveloped. This study analyses the judicial development of unconscionability doctrine in Nigeria through examination of approximately 40 relevant court decisions from 1990 to 2023 and assesses its application to standard form contracts in three key sectors. A doctrinal methodology was adopted, incorporating comparative analysis of doctrinal development in England, South Africa, and Australia. Practitioner interviews with 15 contract lawyers supplemented the analysis. Results indicate that Nigerian courts have applied unconscionability inconsistently, sometimes relying on undue influence, non est factum, and duress as proxy doctrines rather than engaging directly with unconscionability. Standard form contracts in insurance and consumer credit contain exclusion clauses that would likely be unconscionable under developed unconscionability standards. Judicial awareness of unfair contract terms regulation in other jurisdictions is limited. The study fills an important doctrinal gap and concludes that Nigeria requires statutory unfair contract terms legislation applicable to consumer and small business standard form contracts. Recommendations include enactment of an Unfair Contract Terms Act based on the United Kingdom model, incorporating a fairness test for standard form exclusion and limitation clauses.
