A guarantor's form trips up a lot of first-time applicants, mostly because it's easy to confuse with a renewal, which doesn't need one at all.
Here's what the requirement actually covers, and who it applies to.
What the form is for
NIS asks fresh adult applicants for a guarantor's form signed before a Commissioner for Oaths, with a copy of the guarantor's Nigerian passport data page and a photo.
In plain terms: someone vouches for you in writing, in front of an official, and backs that up with their own passport details as part of your passport application.
NIS treats this as a check on identity, not a formality. A form with gaps, or a guarantor who can't produce their own passport data page, holds up the whole file.
Who needs one, and who doesn't
This requirement sits with fresh adult applications only. A standard renewal's document list does not ask for a guarantor at all.
If you're renewing rather than applying for the first time, skip this step and go straight to our renewal documents checklist.
It's worth checking which category you're actually in before you start. Some people assume a long-expired passport means starting "fresh", when NIS still treats it as a renewal for document purposes.
Where the form gets signed
The form is signed before a Commissioner for Oaths, not simply witnessed by anyone with a stamp. That's what gives it the same standing as an affidavit.
Bring the guarantor's own Nigerian passport data page and a photo to that appointment. NIS wants proof of who the guarantor is, not only a signature.
A Commissioner for Oaths is the same official who witnesses affidavits, so the same courts and law offices that handle those can usually handle this too.
The guarantor's other job
Signing the form isn't the end of it. The guarantor also endorses the back of your passport photos, confirming they really are photos of you.
Sort this out before your own biometric appointment, not on the day, since a missing endorsement can hold up an otherwise complete file.
Choosing the right guarantor
NIS's form itself sets out who can act as a guarantor. Read those conditions carefully rather than assuming a parent, sibling or friend automatically qualifies.
Once you have someone who fits, the rest is paperwork: the form, their data page, their photo, and their endorsement on yours.
Chasing a guarantor tends to take longer than any other part of a fresh application, mostly because it depends on someone else's schedule, not just your own. Start here first, before you book a biometric appointment or finalise anything else.
Common mistakes
- Assuming a renewal needs a guarantor, when the requirement is for fresh applications only.
- Getting the form signed by someone other than a Commissioner for Oaths.
- Forgetting the guarantor's photo endorsement until the day of the appointment.
- Leaving the guarantor's paperwork until every other document is already sorted.
Once your guarantor's paperwork is settled, the rest of a fresh application runs through the same NIS portal as any other passport. Our passport renewal guide covers what comes next.
