Islamic Inheritance in Nigeria: A Complete Guide to Faraid and Nigerian Muslim Family Law

Nigeria has one of the largest Muslim populations in Africa, and Islamic inheritance here runs on the usual split: the Quran fixes who inherits and how much, while Nigerian law decides how that share actually gets transferred. What makes Nigeria different from every other country in this series is that "Nigerian law" isn't one system — it's three running side by side, statutory, customary and Islamic, and which one actually gets applied to a Muslim's estate can depend on which state the family lives in as much as on the Faraid calculation itself.

Nigeria's Legal Framework for Muslim Inheritance

Nigeria's inheritance law is genuinely tripartite: statutory law (English-derived, administered through State Probate Registries), customary law (varying by ethnic community), and Islamic law, which is meant to apply as the deceased's personal law whenever the deceased was Muslim. Section 262 of the 1999 Constitution gives the Sharia Court of Appeal jurisdiction over Islamic personal law matters — including inheritance, succession, marriage and guardianship — wherever all parties involved are Muslim.

In practice, that constitutional recognition plays out very differently depending on where in Nigeria a family lives, which is the subject of its own section below.

Sunni and Shia Muslims Inherit Differently — and Nigeria's Maliki Default

This guide covers Sunni Faraid — the fixed-share and residuary system the overwhelming majority of Nigerian Muslims follow, and the system FaraidHub's calculator applies. Nigeria's small Shia minority classifies heirs differently under Shia fiqh; if your family follows Shia jurisprudence, get the calculation from a scholar trained in that system instead.

Within Sunni Islam, Nigeria follows the Maliki madhab by default — the school historically dominant across West Africa, a genuine difference from the Hanafi default across South Asia and the Shafi'i default in Singapore. The core Quranic fixed shares (1/2, 1/4, 1/8, 2/3, 1/3 and 1/6) are identical across all four Sunni madhabs; where the schools differ is in narrower technical areas, not the basic entitlements this guide covers.

The North-South Divide — Where You Live Changes How Faraid Gets Enforced

Twelve northern states adopted Sharia-based legal systems between 2000 and 2002: Zamfara, Kano, Sokoto, Katsina, Kebbi, Yobe, Bauchi, Borno, Gombe, Niger, Kaduna and Jigawa. In these states, a dedicated Sharia Court exists specifically to apply Islamic personal law, with the Sharia Court of Appeal available if a decision is disputed — a legal system built, staffed and trained for exactly this purpose.

Outside those twelve states — including Lagos and most of southern Nigeria — there's no equivalent dedicated court. A Muslim's estate there is still meant to be distributed under Islamic law, since that remains the deceased's personal law regardless of location, but the actual administration goes through the ordinary State Probate Registry and general courts rather than a Sharia-specific one. Getting the Faraid calculation correctly recognised and enforced then depends more on the family's own lawyer, documentation and the presiding judge's familiarity with Islamic law than on a specialised system built for the job. This gap doesn't mean Faraid stops applying outside the Sharia states — it means the burden of getting it applied correctly shifts onto the family.

Getting Letters of Administration for a Muslim Estate

In a Sharia state, a Muslim family typically brings the estate before the Sharia Court, which determines the heirs and their shares under Islamic law and can issue rulings enforceable through the same machinery as any other Nigerian court judgment. Outside the Sharia states, the family applies to the State Probate Registry for a Grant of Probate (where there's a valid will) or Letters of Administration (where there isn't); until administration is formally granted, the estate remains under the oversight of the State's Chief Judge. Several states — including Oyo, Kwara and Jigawa — have gone further and written recognition of Islamic law for a Muslim's intestate estate directly into their Wills Laws, giving families outside the core Sharia-court system firmer statutory ground to insist on Faraid distribution.

Worked Example: Faraid Distribution in Nigeria

A man dies leaving an estate of NGN 48,000,000 after funeral costs and debts are settled, with no valid Wasiyyah bequests. He is survived by his wife, his father and two daughters — no sons, and his mother predeceased him.

With no son, the two daughters take a combined fixed 2/3 of the estate, and the wife takes her fixed 1/8. The father takes his fixed 1/6 — but because there's no son to absorb the remaining residue, the father also inherits what's left over as a residuary heir, on top of his fixed share. The 1/24 residue added to his 1/6 brings his total to 5/24 of the estate. The total comes to exactly NGN 48,000,000. This is the same Faraid arithmetic used everywhere Sunni Muslims live, Maliki or Hanafi; what changes in Nigeria is only which court applies it and how the estate gets formally administered.

Does a Wasiyyah Override Faraid in Nigeria?

No. A Wasiyyah can appoint an executor, record funeral wishes, settle debts and make bequests to people who are not already Quranic heirs — but generally only up to one-third of the estate, and not to an existing heir unless every other heir agrees after death. The remaining estate is still distributed under Faraid, whether the family lives in a Sharia state or not.

Women's Inheritance Rights — Islamic Law vs Customary Law in Nigeria

Here's a point most guides miss entirely: in Nigeria, Islamic law is often the stronger protection for a woman's inheritance, not the weaker one. Many of Nigeria's customary law systems — the ethnic and tribal inheritance traditions that predate and still coexist with both statutory and Islamic law — exclude women from land inheritance altogether, leaving widows and daughters with nothing when in-laws or male relatives claim the estate. Faraid, by contrast, guarantees a woman a fixed Quranic share, even if it's smaller than a son's.

The gap isn't in the law, it's in getting it enforced. In parts of Northern Nigeria, women's right to inherit under Islamic law has still been denied in practice — sometimes because judges or families apply customary norms instead of Sharia, sometimes from straightforward family pressure to give up a claim. The trend is genuinely improving: Sharia courts have increasingly recognised and upheld women's inheritance rights over the past two to three decades. But knowing that Islamic law is on your side is only useful if you're prepared to insist on it rather than defer to whichever system your family finds more convenient.

Practical Checklist for Nigerian Muslim Families

• Register the death and obtain the death certificate.
• Identify every asset and confirm the deceased's state of residence, since it determines which court process applies.
• Settle outstanding debts before anything is distributed.
• Carry out any valid Wasiyyah bequests, within the one-third limit.
• In one of the 12 Sharia states, bring the estate before the Sharia Court; elsewhere, apply to the State Probate Registry for a Grant of Probate or Letters of Administration.
• Calculate each heir's Faraid share — use the calculator below for the Quranic-shares part.
• If a woman's share is being withheld or overridden by customary practice, be prepared to insist on the Islamic-law entitlement explicitly, with legal support if needed.
• Keep the court ruling or Grant/Letters and the calculation with the estate records.
