Estate Planning in Nigeria: The Complete Guide to Wills, Succession, and Protecting Your Family (2026)

Why Nigerians Delay Estate Planning — And Why That’s Costly

Estate planning is frequently deferred because it requires confronting mortality directly, because many people assume it is only relevant to the very wealthy or the very old, and because the absence of a plan does not create any visible, immediate consequence — the cost only becomes apparent to the family left behind, after the person who should have planned is no longer present to address it.

For business owners specifically, the stakes are materially higher. A will is necessary but often insufficient on its own — company shares, control provisions, and the operational continuity of a business require specific succession planning that a general will typically does not address in adequate detail.

What Happens If You Die Without a Will

Dying without a valid will — intestate — means your estate is distributed according to statutory intestacy rules rather than your own wishes. In Nigeria, this can involve a combination of statutory provisions and, in some cases, customary law considerations depending on the nature of the deceased’s marriage and family circumstances, creating outcomes that frequently do not align with what the deceased would have actually wanted.

This is particularly consequential in several common Nigerian family situations: blended families with children from more than one relationship, where intestacy rules may not reflect the deceased’s actual intentions for each child; unmarried partners, who generally have no automatic entitlement under intestacy regardless of the relationship’s duration; business owners, where intestate succession of company shares can create governance paralysis while the estate is administered; and families where the deceased wished to make specific provisions for a dependant, a charity, or an individual outside the standard intestacy categories.

Making a Valid Will in Nigeria

A will must meet specific formal requirements to be valid and enforceable. Under the applicable state Wills Law (for example, the Wills Law of Lagos State), the core requirements are:

• In writing — an oral will has no legal effect for the disposition of property under formal wills legislation
• Signed by the testator (the person making the will), or by someone else in their presence and at their direction
• Witnessed by at least two independent witnesses, present at the same time, who also sign the will
• Witnesses must not be beneficiaries under the will — a gift to a witness or their spouse is generally void, even though the will itself may remain valid
• The testator must have testamentary capacity — understanding the nature of making a will, the extent of their property, and the claims they ought to consider

A well-drafted will should also name an executor (or executors) to administer the estate, specify guardians for minor children where relevant, address specific bequests clearly to avoid ambiguity, and be reviewed periodically — particularly after major life events such as marriage, divorce, the birth of children, or significant changes in asset composition or business interests.

Business Owners: Protecting the Company After You

For business owners, estate planning must go beyond a general will to address the specific mechanics of business succession:

• Share transfer provisions — a will should clearly address what happens to company shares, but this should also be considered alongside the company’s Articles of Association and any shareholder agreement, which may contain their own provisions on share transfer upon a shareholder’s death
• Interim management authority — clarity on who has authority to make operational decisions during the period between death and full estate administration is often overlooked, creating a genuine governance gap at a critical time
• Buy-sell or cross-purchase agreements — for businesses with multiple shareholders, an agreement addressing what happens to a deceased shareholder’s stake (whether other shareholders have a right or obligation to purchase it, and at what valuation) prevents disputes and provides liquidity to the deceased’s estate
• Key person considerations — where the business depends significantly on the deceased’s specific relationships, expertise, or personal guarantees, a succession plan should address how these gaps will be managed

This connects directly to the corporate governance considerations covered in our broader guide to tax and wealth structuring, since the tax treatment of business assets on death and the succession mechanics are closely related planning questions that should be addressed together, not separately.

Probate: What Your Family Must Do After Your Death

Where a valid will exists, the named executor applies for a Grant of Probate, which formally confirms their authority to administer the estate according to the will’s terms. Where no will exists, an interested party (typically a close family member) applies for Letters of Administration, which grants authority to administer the estate under intestacy rules.

The probate process involves identifying and valuing the estate’s assets, settling any outstanding debts and liabilities, and distributing the remaining assets according to the will (or intestacy rules where no will exists). A well-prepared will, with clearly identified assets and a named executor familiar with the estate, generally results in a smoother and faster probate process than an intestate estate, which frequently requires more extensive investigation and can be more prone to disputes among family members over entitlement.

Trusts and Alternative Structures

Beyond a straightforward will, some individuals — particularly those with more complex family circumstances, significant assets, or specific concerns such as providing for a minor or vulnerable dependant over an extended period — may benefit from a trust structure. A trust can provide more controlled, staged distribution of assets over time, rather than an outright transfer upon death, and can offer additional protection and flexibility that a simple will does not provide. Whether a trust structure is appropriate depends heavily on individual circumstances and should be assessed as part of a comprehensive estate planning review.

Common Estate Planning Mistakes

• Assuming a will is only necessary for the very wealthy or elderly. Anyone with assets, dependants, or business interests benefits from a clear estate plan, regardless of age or net worth.
• Never reviewing or updating an existing will. A will drafted years ago, before marriage, children, or significant business changes, may no longer reflect the testator’s actual circumstances or wishes.
• Naming a beneficiary as a witness. This can void that specific gift under the will, even where the rest of the will remains valid — a straightforward drafting error with real consequences.
• Treating a general will as sufficient for business succession. As discussed above, business owners require specific additional planning beyond a general will to address share transfer, interim management, and buy-sell arrangements.
• Not communicating the existence and location of the will to the family or named executor. A perfectly valid will that cannot be located after death creates the same practical problems as having no will at all.
