More than half of Nigerian children under five have no birth certificate on record, according to UNICEF, leaving millions of adults today with no formal proof of their date of birth. That single gap follows people for life, surfacing at the worst possible moments: a passport application stalls, a job offer hangs on hold, a school admission gets rejected, all because no birth certificate exists to confirm an applicant’s age. An Age declaration affidavit exists precisely to close this gap, yet many Nigerians discover the requirement only after an urgent deadline forces the issue. Additionally, a Nigerian abroad trying to process a visa, a passport renewal, or a school application back home, and the pressure multiplies fast: no birth certificate, no clear starting point, and no idea how an Affidavit in Nigeria even works from thousands of miles away.
Anyone facing this exact situation keeps circling back to the same questions:
- What is an Age declaration affidavit, and who actually needs one?
- Which court or agency handles this process in Nigeria?
- Can a Nigerian abroad complete an Affidavit in Nigeria without flying home?
- What documents support an age declaration when no birth certificate exists?
- How long does the entire process take, and what does it cost?
Searching for straight answers across scattered forums rarely settles these questions with any confidence. This guide breaks down exactly how to obtain an Age declaration affidavit in Nigeria, step by step, using the correct legal process and required documents. DocuTrust Africa takes it further, handling the sworn declaration, court process, and follow- through, so Nigerians at home and abroad settle this once and move forward without delay.

Request an AffidavitWhat Is an Age Declaration Affidavit?
An Age declaration affidavit stands as a sworn legal statement that declares a person’s date of birth, or an approximate age, in the absence of an official birth certificate. Nigerian law recognizes this document as valid proof of age once a Commissioner for Oaths witnesses and stamps it, which makes it one of the most requested forms of Affidavit in Nigeria today.
The deponent, or the person making the declaration, typically provides details such as their full name, place of birth, parents’ names, and estimated date of birth, then swears to the accuracy of this information before a court official. This process gives someone without a birth certificate a legally recognized alternative for confirming their age across schools, employers, and government agencies.
Understanding an Affidavit in Nigeria: The Legal Basis
Every Affidavit in Nigeria, including an Age declaration affidavit, derives its authority from the Oaths Act, Laws of the Federation of Nigeria (LFN) 2004, alongside the Oaths (Amendment) Act 2016, which introduced further procedural updates to the swearing process. This law authorizes specific officials to witness and validate a sworn declaration:
- A Commissioner for Oaths at a High Court or Magistrate Court
- A Notary Public
- Judges of the Federal High Court, Court of Appeal, and Supreme Court, in defined circumstances
The Evidence Act 2011 treats affidavit content as sworn testimony, which means an Age declaration affidavit carries the same legal weight as testimony given in open court. Providing false information on any Affidavit in Nigeria exposes the deponent to criminal liability, so accuracy matters as much as speed throughout this process.
Why Nigeria’s Birth Registration Gap Makes Age Declaration Affidavits Necessary
Nigeria’s birth registration numbers explain why so many citizens eventually need an Age declaration affidavit. The 2013 Demographic and Health Survey reported that only 30% of children under five had their births registered, while Multiple Indicator Cluster Surveys placed the rate at 23% in 2007 and 42% in 2011. Civil registration data further shows birth registration currently sitting around 53% nationally.
The Births, Deaths, etc. (Compulsory Registration) Act, No. 69 of 1992, established the National Population Commission (NPC) and made birth registration a legal requirement in Nigeria. Despite this law, gaps in access, awareness, and rural coverage leave millions of Nigerians without a birth certificate, which pushes them toward an Age declaration affidavit as the practical route to proving their age later in life.
Who Needs an Age Declaration Affidavit?
Several groups of Nigerians commonly require an Age declaration affidavit:
- Adults born before the NPC’s full operational rollout, who never received a birth certificate
- Individuals whose birth certificate got lost, damaged, or was never issued
- Anyone applying for a first- time international passport without a birth certificate
- Job applicants whose employer requires formal proof of age
- Students applying for school admission or examination registration
- Nigerians abroad who need to regularize their age records for visa, immigration, or consular purposes
Recognizing which category applies helps determine the exact type of Affidavit in Nigeria required, since age declaration processes differ slightly for minors and adults.
Documents Required to Obtain an Age Declaration Affidavit
Gathering the right documents before visiting court speeds up the entire process. Typical requirements include:
| Requirement | Purpose |
|---|---|
| Valid means of identification | Confirms the deponent’s identity |
| Passport photograph | Attached to the sworn affidavit |
| Parents’ details (names, if known) | Supports the declaration of parentage |
| Place and estimated date of birth | Forms the core content of the affidavit |
| National Identification Number (NIN) | Required to commence the NPC attestation process afterward |
| Active phone number | Needed for correspondence during processing |
The National Population Commission requires applicants to hold a valid NIN before beginning the birth certificate attestation process that typically follows an Age declaration affidavit. Nigerians born locally but currently residing abroad can also obtain a NIN through any designated overseas NIN processing center, which keeps this step accessible for the diaspora.
Age Declaration Affidavit for Minors vs Adults
Nigerian procedure treats minors and adults differently when it comes to age declaration.
| Category | Process | Outcome |
|---|---|---|
| Under 18 years | A parent or legal guardian swears the Age declaration affidavit on the child’s behalf | NPC issues a standard birth certificate |
| 18 years and above | The individual swears their own Age declaration affidavit | NPC issues an Attestation of Birth, backed by the sworn affidavit |
For applicants under 17, the presence of a parent remains a standard requirement before an Age declaration affidavit gets accepted at the NPC. For adults, the NPC issues an attestation letter that backs up the sworn declaration rather than a full birth certificate, since a birth certificate cannot retroactively cover someone born decades earlier without an original hospital or local government record.

Request an AffidavitReasons and Uses of an Age Declaration Affidavit
An Age declaration affidavit supports far more than one single purpose. Common uses include:
- First- time international passport applications, where no birth certificate exists
- School admissions and examination registrations requiring proof of age
- Employment applications, particularly for public service roles
- Marriage registration, where age verification forms part of the legal process
- Visa and immigration applications for Nigerians relocating or traveling abroad
- Pension and retirement benefit claims that require confirmed date of birth
Each of these situations treats a properly sworn Affidavit in Nigeria as credible, legally recognized proof of age, provided the NPC has validated it through attestation.
From Affidavit to Attestation: What Happens at the NPC
Swearing an Age declaration affidavit marks only the first half of the journey. The National Population Commission remains the only statutory agency authorized to issue birth documents in Nigeria, and any birth- related document not issued by the NPC may not gain acceptance for official purposes.
After swearing the affidavit, applicants typically follow these steps at the NPC:
- Start an online application. Applicants with a NIN and the sworn Affidavit in Nigeria can begin the process through the NPC portal.
- Upload the affidavit and supporting documents. The NPC requires the properly stamped Age declaration affidavit alongside identification and NIN details.
- Pay the official NPC fee. Payment runs through the NPC portal during the application process.
- Wait for verification. The NPC reviews the submitted Age declaration affidavit and supporting details before issuing a certificate or attestation.
- Receive the attestation or birth certificate. Applicants aged 17 and above receive an Attestation of Birth, while those under 17 receive a standard birth certificate.
This two- stage journey, from court to NPC, explains why many Nigerians find the process confusing without proper guidance.
How Nigerians Abroad Can Obtain an Affidavit in Nigeria Remotely
Nigerians living in London, Houston, Toronto, or elsewhere abroad often assume they must travel home to complete an Age declaration affidavit. That assumption does not always hold true. Several Nigerian courts now support remote deposition through e- Affidavit platforms, allowing a Commissioner for Oaths to verify identity and witness a signature virtually.
A few practical points matter for the diaspora audience:
- Obtain a NIN in advance through an overseas NIN processing center, since applicants born in Nigeria but currently living abroad can register without traveling home.
- Gather scanned, high- resolution copies of identification and any available birth- related documents before starting the process.
- Confirm which court or platform supports remote swearing of an Affidavit in Nigeria before beginning.
- Budget extra time for coordinating between court processing and NPC attestation across different time zones.
Coordinating a two- stage process across an ocean creates real friction, and a single missed detail can stall a passport renewal, a visa application, or a job offer for months. This is precisely where Docutrust Africa closes the distance gap helping clients complete the process without unnecessary travel or confusion.
Common Mistakes to Avoid
- Providing inconsistent details. Any mismatch between the Age declaration affidavit and other identification documents can trigger rejection at the NPC.
- Skipping the NIN registration step. Attempting to start the NPC process without a valid NIN causes unnecessary delays.
- Using unverified agents. Fraudulent affidavits circulate through unofficial channels, and using one violates the Oaths Act while risking outright rejection by government agencies.
- Assuming one document covers every purpose. Some institutions request the original sworn affidavit, while others accept only the NPC- issued attestation, so confirm requirements before submission.
- Delaying the process until a deadline looms. Passport applications, job offers, and school admissions rarely pause for a lengthy affidavit and attestation process, so starting early avoids last- minute pressure.

Request an AffidavitFrequently Asked Questions on Age Declaration Affidavit
What is the difference between an Age declaration affidavit and a birth certificate?
An Age declaration affidavit is a sworn court statement declaring a person’s estimated date of birth, while a birth certificate is an official NPC- issued document confirming birth details. The NPC often requires a sworn affidavit before issuing an attestation or replacement certificate for someone without an original birth record.
Who can swear an Age declaration affidavit for a child?
A parent or legal guardian must swear the Age declaration affidavit on behalf of anyone under 18 years old, since minors cannot legally swear affidavits for themselves.
Can Nigerians abroad obtain an Affidavit in Nigeria without traveling home?
Yes, in many cases. Several courts now support remote swearing through e- Affidavit platforms, and applicants can register for a NIN through overseas processing centers before completing the NPC attestation process.
Do I need a NIN before obtaining an Age declaration affidavit?
Yes. The National Population Commission requires applicants to hold a valid NIN before commencing the birth certificate attestation process that follows a sworn affidavit.
What happens after I swear my Age declaration affidavit?
Submit the sworn document to the nearest NPC office, along with your NIN and identification, to begin the attestation or certificate issuance process.
Is an Age declaration affidavit legally binding?
Yes. The Evidence Act 2011 treats every properly sworn Affidavit in Nigeria as sworn testimony, and providing false information exposes the deponent to criminal liability under Nigerian law.
