Summary
Section 26(2)(b) of Nigeria's Constitution provides a registration route for a person who was born outside Nigeria, is of full age and capacity, and has a Nigerian-citizen grandparent. This is the relevant family route when an adult born abroad cannot claim citizenship by birth through a Nigerian parent but can prove the required grandparent link.
Registration is discretionary. The President must be satisfied about the applicant's character, intention to be domiciled in Nigeria, and Oath of Allegiance before granting a certificate.
Eligibility
The applicant must show all of the following:
- birth outside Nigeria;
- full age and capacity;
- at least one grandparent who is or is deemed to be a Nigerian citizen;
- good character;
- a clear intention to be domiciled in Nigeria; and
- completion of the constitutional Oath of Allegiance.
Section 31 can deem a parent or grandparent to be a Nigerian citizen where, at the applicant's birth, that ancestor would have been a citizen by birth had the ancestor been alive at independence. This is a historical-status rule, not a substitute for proving the family chain.
The Ministry of Interior's current checklist asks for the applicant's birth certificate, passport and residence documents, evidence of the Nigerian citizenship in the family line, relevant marriage records, and guarantor documents. The checklist also mentions parent and great-grandparent evidence. That evidence may help prove that the applicant's grandparent was Nigerian, but the Constitution's direct section 26(2)(b) test is keyed to a Nigerian-citizen grandparent.
Section 28 makes registration conditional on an applicant who holds another citizenship acquired other than by birth effectively renouncing it within a period of no more than 12 months after registration. This issue should be resolved before the applicant makes any irreversible filing.
What This Route Allows
An approved applicant becomes a Nigerian citizen by registration after the required steps are completed. The person may then apply separately for a Nigerian passport and other citizenship documents.
Registration can create a stronger long-term status than residence permission, but it remains acquired citizenship. Constitutional rules on dual nationality and possible deprivation differ from those for citizens by birth.
What This Route Is Not
This is not citizenship automatically inherited from any Nigerian ancestor. A great-grandparent alone is not stated as a direct qualifying relationship in section 26(2)(b), and the applicant must be born outside Nigeria and of full age and capacity.
It is also not citizenship by birth. A person born outside Nigeria with a Nigerian-citizen parent should first assess section 25, because that person may already be a citizen by birth rather than needing discretionary registration.
Next Steps
- Map the applicant-to-parent-to-grandparent relationship with official civil records.
- Prove the grandparent's Nigerian citizenship, using the historical deeming rule only where its facts are met.
- Gather current passport, residence, marriage/name-change, character, and guarantor documents from the Ministry checklist.
- Prepare evidence of a real intention to be domiciled in Nigeria.
- Review all other citizenships under section 28 and confirm the current procedure with the Ministry before filing or renouncing anything.
