The Enforceability of Prenuptial Agreements Under Nigerian Matrimonial Law

Prenuptial agreements, concluded between prospective spouses before marriage to regulate their financial and property rights upon divorce or death, occupy a contested legal space in Nigeria where their enforceability has never been definitively resolved by statute or superior court decision. This study examines the legal status and enforceability of prenuptial agreements under Nigerian matrimonial law, evaluating the Matrimonial Causes Act 1970, the Law of Contract, equitable principles, and the constitutional right to property. Using a doctrinal methodology, the research analyses the developing common law position in England and Commonwealth jurisdictions and compares this with the Nigerian judicial treatment of prenuptial arrangements in the few cases where such agreements have been raised. The study is supplemented by interviews with 30 family law practitioners in Lagos, Abuja, and Port Harcourt who report increasing client demand for prenuptial arrangements among high-net-worth individuals. Findings reveal significant legal uncertainty, with different courts taking divergent views on whether prenuptial agreements constitute valid contracts or are contrary to public policy as agreements in contemplation of divorce. Recommendations include statutory recognition of prenuptial agreements with safeguards for weaker parties, mandatory independent legal advice requirements, disclosure obligations, and a three-year waiting period before enforcement to ensure freedom from duress.
