Can You Disinherit a Biological Child in a Will in Nigeria?

Generally yes, under statutory wills law, a testator has testamentary freedom to distribute their property as they choose, but customary limitations and statutory reasonable provision rules apply in certain states.

Under the English Wills Act 1837 and various state Wills Laws, an adult of sound mind has the legal right to decide who inherits their estate, and there is no automatic entitlement for biological children.

However, some states, like Lagos State under Section 2 of its Wills Law, allow a disinherited child or dependant to apply to court for financial provision from the deceased’s estate if left without adequate maintenance.

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.

The court will assess the applicant’s financial circumstances, the size of the estate, the child’s conduct toward the deceased, and any reasons explicitly documented by the testator for the exclusion.

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

Under customary law, particularly in jurisdictions where customary inheritance practices are preserved, completely disinheriting children without recognized customary justification can lead to the will being challenged.

For instance, under Benin customary law, the Igiogbe (the ancestral home where the deceased lived and died) must pass to the first-born son, and a will attempting to bequeath it to another person is void to that extent.

A testator who deliberately intends to disinherit a biological child should clearly document the reasons in the will or in an accompanying memorandum to provide evidence of deliberate, sound-minded intention.

Disinherited children often challenge wills on grounds of lack of testamentary capacity, undue influence, or suspicious circumstances surrounding the execution of the will.

Ensuring that the will is properly drafted by an experienced probate lawyer, attested by independent witnesses, and deposited at the High Court Probate Registry minimizes the risk of successful challenges.

Medical certificates confirming the testator’s mental fitness on the date of execution provide strong evidence against future claims that the testator was senile or manipulated.

Family disputes over disinheritance can exhaust estate assets in prolonged litigation. Open family communication during lifetime or creating inter-vivos trusts can often achieve the testator’s goals more smoothly.

Testamentary freedom remains a cornerstone of Nigerian succession law, but exercising it to exclude biological offspring requires precise legal drafting to withstand vigorous challenges after death.

In Nigeria, the law exists to protect every citizen from exploitation and injustice, regardless of financial status or social standing. The courts are open to all, and regulatory agencies stand ready to enforce your rights.

Do not allow ignorance of the law to work against you. A brief consultation with a qualified Nigerian legal practitioner can clarify your rights and the remedies available in your specific situation.

For direct regulatory verification, official complaints, or accessing statutory registers without third-party fees, members of the public can consult the official portal of the Medical and Dental Council of Nigeria (MDCN).

Taking proactive legal action at the earliest sign of a rights violation is always better than waiting until the damage becomes irreversible. Nigerian courts have consistently protected citizens who assert their rights promptly and lawfully.

Ignorance of the law is no excuse.

  4. What specific documentation or contemporaneous evidence is most critical for a claimant or petitioner to assemble before instituting an action regarding Can You Disinherit a Biological Child in a Will in Nigeria? in a Nigerian court?

    1. Spot-on question. From our regulatory review across Nigerian superior courts of record, the foundation of every successful action lies in verified corporate and statutory records (such as certified true copies of CAC status reports, licenses, and statutory notices). Claimants who present a contemporaneous, unchallenged documentary record routinely succeed on the balance of probabilities without prolonged trial delays.

    1. Excellent question on the evidentiary threshold. Under Nigerian jurisprudence, the standard of proof depends squarely on the nature of the averments. In civil proceedings generally, the standard is the balance of probabilities (Section 134, Evidence Act 2011). However, where an allegation of bad faith borders on fraud, criminality, or corrupt inducement, Section 135(1) of the Evidence Act mandates that such specific allegation must be proved beyond reasonable doubt. The Supreme Court has consistently held that general averments of mala fides are insufficient; the claimant must plead specific, cogent particulars showing active procedural impropriety.
