Document Legalisation for Nigeria: FCDO Apostille and High Commission Attestation
Why Standard Apostilles Don't Work for Nigeria
Nigeria is not a member of the 1961 Hague Apostille Convention. That single fact transforms a normally straightforward document verification into a two-stage legalisation process: the High Commission stage takes five to ten working days, while FCDO processing adds one to two working days through an express agent or up to 30 days by standard post. The total can cost several hundred pounds.
For families repatriating remains from the UK, this process is unavoidable. Nigerian courts, banks, pension fund administrators, and the Probate Registry all refuse to recognise a UK-issued death certificate, grant of probate, or power of attorney without both an FCDO apostille and a Nigerian High Commission consular stamp.
Stage 1: FCDO Paper Apostille
The original UK death certificate — not a photocopy, not a solicitor-certified copy, and not a scanned PDF — must be submitted to the Foreign, Commonwealth & Development Office (FCDO) Legalisation Office at Hanslope Park, Milton Keynes.
The FCDO verifies the registrar's wet-ink signature on the certificate and attaches a physical paper apostille to the document. This apostille confirms that the certificate was genuinely issued by a UK authority.
The e-Apostille trap. The FCDO now offers electronic apostilles for certain document types. The Nigerian High Commission categorically rejects these. Only a physical, paper-based apostille is accepted. If you submit a document with an e-Apostille to the High Commission, it will be returned, and you'll need to restart the FCDO process with the correct format.
Processing Times and Costs
- Express (via accredited agent): 1–2 working days, £79–£97
- Standard postal submission: Up to 30 days
Express processing through a legalisation agent is almost always worth the cost. Standard postal submission is vulnerable to Royal Mail delays, and every day the apostille takes is another day of mortuary storage fees accumulating on the body.
Stage 2: Nigerian High Commission Consular Attestation
Once the FCDO apostille is attached, the document goes to the Nigerian High Commission at 9 Northumberland Avenue, London, WC2N 5BX.
The consular section verifies the FCDO apostille and applies its own consular stamp and signature. This second layer of authentication is what makes the document legally valid in Nigeria.
What to Submit
- The original apostilled death certificate
- A complete photocopy of the entire document bundle
- A photocopy of the applicant's passport
- A formal cover letter addressed to the High Commissioner, stating the purpose of legalisation and the names of all parties involved
- Postal orders for the fee (typically £45 per document plus £20 administrative charge)
Payment: Postal Orders Only
The High Commission accepts payment exclusively via UK postal orders from the Post Office. Cash, personal cheques, bank drafts, and credit or debit cards are all rejected. Purchase postal orders before your appointment — Post Office branches in central London often have limited stock of higher-denomination orders.
Processing: 5–10 Working Days, No Express Option
The High Commission does not offer expedited or same-day processing. Submit during the consular section's stated hours of 9:00 AM to 1:00 PM, Monday to Friday. There is no way to pay more for faster turnaround.
This means you need to factor five to ten working days (up to two calendar weeks) into your repatriation timeline just for the consular stage, after the FCDO apostille is already complete.

Which Documents Need Legalisation
Not every document in the repatriation process requires the full two-stage treatment:
| Document | Legalisation Needed? | Why |
|---|---|---|
| UK death certificate | Yes — FCDO + consular | Required for Nigerian probate, bank claims, and pension recovery |
| UK grant of probate | Yes — FCDO + consular | Required to reseal the probate in Nigerian courts |
| Embalming certificate | No separate FCDO + consular legalisation | Include it in the Laissez-Passer and airline paperwork; it is not itself double-legalised |
| Coroner Form 103 | No (airline use only) | UK departure clearance — not used in Nigeria |
| Freedom from infection certificate | No separate FCDO + consular legalisation | Include it in the Laissez-Passer, airline, and Port Health paperwork; it is not itself double-legalised |
If the deceased held assets in Nigeria and you'll need probate resealing, legalise both the death certificate and the grant of probate at the same time. Submitting them together saves a separate trip to both the FCDO and the High Commission.
Common Mistakes That Cause Rejection
Submitting photocopies. The High Commission requires the original GRO-certified death certificate with the registrar's wet-ink signature or official seal. Plain photocopies and solicitor-certified copies are rejected immediately.
Using an e-Apostille. As noted above, the High Commission only accepts paper apostilles. If the FCDO issued an electronic version, you must resubmit for the paper format.
Missing the cover letter. The High Commission expects a formal typed letter addressed to the High Commissioner. This isn't a formality — applications without a cover letter are returned without processing.
Wrong payment method. Arriving with cash or a credit card means leaving without submitting. Postal orders must be purchased in advance.
