Analytical Study of the Burden of Proof in Civil Fraud Claims in Nigerian Commercial Litigation

Civil fraud claims in Nigerian commercial litigation present unique evidentiary challenges because fraud must be proved to a standard higher than the ordinary balance of probabilities, yet lower than the criminal standard of proof beyond reasonable doubt. This study provides an analytical examination of the burden and standard of proof in civil fraud claims in Nigerian commercial courts, reviewing decisions from the Supreme Court, Court of Appeal, and commercial divisions of state High Courts between 2016 and 2024. Using a doctrinal methodology, the research analyses how Nigerian courts have articulated and applied the elevated civil fraud standard in banking fraud, corporate misconduct, and contract misrepresentation cases, comparing the Nigerian approach with developments in English, Australian, and Ghanaian civil fraud jurisprudence. Interviews with 25 commercial fraud litigators in Lagos and Port Harcourt provide practitioner perspectives on proof challenges in fraud cases. Findings reveal judicial inconsistency in defining and applying the standard of proof for fraud, with some courts apparently reverting to the balance of probabilities and others requiring near-criminal certainty, creating doctrinal confusion and strategic uncertainty. The study contributes an original analytical framework for rationalising the civil fraud standard in Nigerian law. Recommendations include clear judicial guidelines from the Supreme Court on civil fraud proof standards, enhanced judicial training on fraud evidence, and legislative clarification of fraud pleading requirements in commercial cases.
