How to Manage a UK and Nigerian Estate After Death in Two Countries

The Core Problem: Two Countries, Two Probate Systems, One Deadline Pressure

When a Nigerian national dies in the UK with assets in both countries, the surviving family faces two separate estate administration processes running simultaneously under different legal systems, different document requirements, and different timelines. The UK-side estate (bank accounts, pension, property, tax liabilities) operates under English, Scottish, or Northern Irish probate law. The Nigerian-side estate (bank accounts, property, NIN-linked assets, pension fund) operates under the Administration of Estates Law of the relevant state. Neither system waits for the other, and a mistake on one side creates cascading delays on the other.

The Nigerian Dies in the UK — Family Guide covers this dual-jurisdiction process end to end with a worked IHT domicile example and the exact document sequence that prevents rejection at each probate registry. If you are only dealing with Nigerian-side estate issues after a domestic death, the estate settlement and probate guides for Nigeria cover that separately.

The Two Parallel Tracks

UK-Side Estate: What Freezes and What Triggers Probate

On the UK side, the deceased's sole-signatory bank accounts are frozen the moment the bank receives a death notification. Joint accounts with survivorship continue to function, but sole accounts — including savings, ISAs, and investment platforms — are locked. The bank will not release funds without either a Grant of Probate (if there's a will) or a Grant of Letters of Administration (if intestate).

For estates above the applicable tax-free IHT nil-rate band, UK Inheritance Tax is payable before probate is granted. This creates a cash-flow trap: the estate's money is frozen, but HMRC wants tax paid before it releases the money. The standard workaround is a Direct Payment Scheme, where the bank pays HMRC directly from the frozen account before releasing the remainder to the executor.

For Nigerian nationals, the UK IHT liability depends on domicile and the applicable UK rules, not citizenship. A Nigerian citizen who was UK-domiciled or deemed domiciled under those rules may be liable on their worldwide estate — including Nigerian property and bank accounts. The guide includes a worked example showing how this domicile issue applies; cross-border double-taxation questions require professional advice.

Nigerian-Side Estate: Immediate Freeze, Long Probate

On the Nigerian side, financial institutions enforce an immediate hard freeze on all sole-signatory bank accounts, investment portfolios, and mobile money wallets the moment they receive formal notification of the account holder's death. UK probate timelines vary by jurisdiction and estate; Nigerian Letters of Administration take a minimum of six months and commonly stretch to nine months.

For an intestate estate, the Probate Registry of the High Court requires a joint application (minimum two, maximum four administrators), an assets inventory that lists every account and property by name, and—where Nigerian-issued records are being used—15–20 Certified True Copies of the death certificate from the National Population Commission or relevant Local Government Area. If the death occurred in the UK, the UK death certificate must be fully legalised — FCDO paper apostille, then consular stamp from the Nigerian High Commission in London — before the Probate Court will accept it. Electronic apostilles and solicitor-certified copies are rejected outright, halting the application indefinitely.

Pension Fund Administrators (PFAs) add a further documentation barrier. To release the deceased's Retirement Savings Account balance, the PFA requires the Letters of Administration to explicitly include the phrasing "Pensions with [Specific PFA Name]" in the court-approved asset inventory. If the estate inventory omits this exact wording, the PFA rejects the claim, and the administrators must return to the Probate Registry for an amended grant — adding months.

The Sequencing That Matters

The critical insight for dual-jurisdiction estates is that document legalisation is the bottleneck that gates both tracks. The UK death certificate must be legalised (FCDO apostille plus High Commission consular stamp) before the Nigerian probate process can begin. But the same death certificate must also be presented to UK authorities for the probate process in England, Scotland, or Northern Ireland. This means you need multiple certified copies from the outset — the guide recommends ordering at least six GRO-certified originals, because the Nigerian legalisation and probate steps require original certified documents rather than photocopies.

Recommended parallel execution:

1. Week 1: Register the death in the UK. Order six certified death certificates. Notify the deceased's UK banks (triggers freeze but starts the clock on their bereavement process). De-register the deceased's NIN and BVN at a NIMC office in Nigeria to prevent SIM-swap fraud on dormant accounts.

2. Weeks 2–3: Submit the FCDO paper apostille application (express is one working day, standard post takes up to 25 working days). Simultaneously, begin the UK probate application if assets are solely in the deceased's name.

3. Weeks 3–5: After the FCDO apostille is returned, submit the apostilled death certificate to the Nigerian High Commission for consular legalisation (five to ten working days, no express option). In parallel, the UK probate application continues its own timeline.

4. Week 6 onward: With the fully legalised death certificate, file the Letters of Administration application at the Nigerian Probate Registry. This six-to-nine-month process runs concurrently with any remaining UK estate administration.

The guide provides a Document Legalisation Tracker and an Estate Asset Inventory (covering both UK and Nigerian assets) to manage these parallel workflows.

Who This Is For

• Families of Nigerian nationals who died in the UK and left assets in both countries — bank accounts, property, pensions, or investments on either or both sides
• Executors or administrators named in a will that covers both UK and Nigerian assets, needing to understand which jurisdiction's probate process to initiate first
• Family members tasked with protecting Nigerian-side assets (bank accounts, NIN, BVN) from fraud during the extended probate timeline
• Solicitors or estate planners advising clients on cross-border estate structures involving the UK and Nigeria

Who This Is NOT For

• Families dealing with an estate entirely within the UK (no Nigerian assets) — standard UK probate guides apply
• Families dealing with an estate entirely within Nigeria (no UK assets and the death occurred in Nigeria) — the domestic Nigerian estate settlement guides on this site cover that process
• Estates involving countries other than the UK and Nigeria — different legalisation pathways and bilateral agreements apply

The Fraud Window Nobody Warns You About

Between the death notification and the grant of Letters of Administration in Nigeria, access to the estate remains restricted for six to nine months minimum. Fraudsters in Nigeria actively monitor death announcements and obituaries to identify dormant accounts. Armed with the deceased's NIN, phone number, or basic personal details, they execute SIM swaps, access mobile banking apps, and drain funds or take out loans in the deceased's name.

The first 30 days after death are the highest-risk window. De-registering the NIN and BVN at a NIMC office and hand-delivering a formal notification letter to each bank's bereavement desk are the two most time-critical steps on the Nigerian side. These steps cost nothing and can be done while the UK document legalisation is still in progress — but families focused entirely on repatriation logistics often neglect them until it is too late.

Frequently Asked Questions

Does UK probate give me access to Nigerian bank accounts?

No. A UK Grant of Probate has no direct legal force in Nigeria. Nigerian banks require Nigerian Letters of Administration or a Nigerian Grant of Probate; for Nigerian assets, a UK grant must be formally resealed by the relevant Nigerian High Court before it can be used there. However, the UK death certificate — once legalised through the FCDO and High Commission — is the foundational document for starting the Nigerian probate application. Without it, the Nigerian Probate Registry will not accept the application at all.

Can I use a Nigerian power of attorney to access UK bank accounts?

No. UK financial institutions require a UK Grant of Probate or Letters of Administration issued by an English, Scottish, or Northern Irish court. A Nigerian power of attorney — even one drafted under the Powers of Attorney Act — has no standing with UK banks. The reverse is also true: a UK Lasting Power of Attorney ceases on death and cannot be used to access Nigerian-side assets.

What if the deceased had no will in either country?

If the deceased died intestate, both jurisdictions apply their own intestacy rules independently. In the UK, the applicable jurisdiction's intestacy rules determine who inherits the UK assets. In Nigeria, the applicable intestacy law depends on the deceased's ethnic and religious background — the Marriage Act, Yoruba customary law, Igbo customary law, Hausa/Islamic law, or state-specific statutes each produce different distributions. The Nigerian Probate Registry determines which law applies. The guide covers this with the specific documentation each path requires.

How do I avoid paying Inheritance Tax twice on the same asset?

Cross-border double-taxation relief is fact-specific and should be checked with a UK/Nigerian tax professional. The guide includes a worked domicile analysis showing why the deceased's UK domicile or residence history and the location of assets matter for IHT liability.
