Can a Person Sued for Child Support Claim Infertility as a Defense in Nigeria?

Yes. A defendant in a paternity or child maintenance suit can raise medical infertility or sterility as a complete defense, provided it is supported by conclusive medical evidence.

Under Nigerian evidence and family law, the legal presumption of paternity can be rebutted by cogent medical proof demonstrating that the alleged father was physically incapable of procreation.

Medical evidence showing conditions like permanent bilateral azoospermia, anatomical sterility, or post-surgical vasectomy prior to the conception window creates an unshakeable rebuttal.

Step-by-Step Procedure to Resolve This Legal Matter:

1. Preserve Contemporaneous Evidence: Collate physical receipts, verified bank timestamps, stamped letters, and electronic communication logs prior to formal intervention.
2. Deliver Statutory Pre-Action Notice: Issue a formal written demand outlining the specific statutory breach and giving the opposing party statutory time to remedy the grievance.
3. Engage Accredited Legal Counsel: Initiate judicial proceedings before the competent court of record or submit an official petition to the relevant regulatory commission.

However, a mere verbal assertion of infertility will be dismissed by the court as self-serving without accredited clinical and laboratory verification.

Key Evidential Considerations & Statutory Benchmarks:

• Documented statutory breach and verified timeline of events.
• Jurisdictional competence of the regulatory agency or superior court.
• Contemporaneous written correspondences, notices, and financial records.
• Quantifiable proof of pecuniary loss or civil rights violation.

“The rule of law ensures that statutory rights and duties cannot be compromised by informal arrangements or administrative fiat; every citizen has the constitutional right to due process.”
— Nigerian Legal Precedent & Constitutional Jurisprudence

The court will immediately order the defendant to undergo an independent, court-supervised semen analysis and DNA paternity test at a recognized teaching hospital.

If the certified medical tests establish that the defendant produces zero viable sperm and the DNA test excludes biological paternity, the suit must fail.

The court will dismiss the child maintenance claim against the defendant and discharge all interim financial orders previously imposed.

The mother will then bear the sole responsibility for maintenance or be required to institute fresh proceedings against the actual biological father.

A defendant falsely accused of paternity can also counter-claim for the recovery of all financial support previously paid under the mistaken belief of paternity.

Courts in Nigeria award special damages for money had and received where a mother deliberately deceived a man into maintaining a child known to belong to another.

Medical science provides absolute clarity in paternity disputes. The law will never force a sterile or biologically excluded man to pay child support for another’s child.

Biological parentage remains the bedrock of child support. Conclusive medical proof of infertility completely exonerates a falsely accused defendant in court.

In Nigeria, statutory rights and constitutional protections exist to shield ordinary citizens from exploitation, abuse of official power, and predatory commercial arrangements. The courts remain accessible, and regulatory bodies actively intervene to hold wrongdoers accountable.

Do not allow ignorance of the legal system or fear of intimidation to stop you from asserting your lawful rights. Consulting a certified Nigerian legal practitioner early provides strategic clarity and protects your personal and commercial interests.

Taking decisive, well-documented legal steps promptly is far more effective than waiting until violations cause permanent financial or emotional damage. Nigerian courts consistently reward diligent parties who assert their legal rights without unreasonable delay.
