Nigerian Age Declaration Affidavit for NPC Birth Attestation (Template)

What This Template Helps You Do

This template helps you create a properly formatted age declaration affidavit that the National Population Commission (NPC) will accept for birth attestation applications. The affidavit is the required prerequisite document you must swear at a Nigerian High Court before NPC can issue your birth attestation certificate.

Without this sworn affidavit, you cannot obtain an NPC attestation certificate for passport applications, visa processing, NIN registration, or international document use. Using the wrong format leads to NPC rejection, wasted court fees, and processing delays that can derail critical immigration timelines.

Frequently Asked Questions about Nigerian Age Declaration Affidavit for NPC Attestation

Q: Which version should I use if I am abroad?

A: Use Version B (Parent/Sibling Declaration). Your parent or older sibling in Nigeria swears the affidavit on your behalf at a Nigerian High Court. This is the standard and most widely accepted method for diaspora Nigerians.

Q: Can I swear this affidavit at a Nigerian embassy abroad?

A: Some embassies offer this service but availability varies by location. However, the parent/sibling declaration sworn in Nigeria (Version B) is the most reliable method that all NPC offices and foreign immigration authorities accept without question.

Q: How long does the affidavit remain valid?

A: Age declaration affidavits generally do not expire. However, some institutions may prefer recently sworn affidavits. The NPC typically accepts affidavits of any age if properly formatted.

Q: Do I need to authenticate/legalize this affidavit before using it?

A: It depends on the country of intended use. Some countries (such as the Netherlands and Belgium) require you to authenticate/legalize the age declaration affidavit (along with the NPC birth attestation) at the Nigerian Ministry of Foreign Affairs before it can be accepted for immigration purposes. You need to find out from your destination country if this is required. 

Q: Can I use this affidavit for purposes other than NPC attestation?

A: While designed specifically for NPC attestation, the affidavit may be accepted by other institutions for age verification. However, the NPC attestation certificate you obtain with it is the proper document for most official purposes.

Q: What if my information is wrong after swearing?

A: You must swear a new affidavit. Alterations to sworn affidavits are not acceptable. Ensure all information is correct before swearing at the court.

Q: Will the NPC reject my affidavit if I use this template?

A: You do not simply print and submit this template itself to the NPC, It is just a template that guides you on how to correctly prepare your affidavit at the High Court.
