Independent Verification Desk — Nigeria
A claim is only as good as the evidence set beside it.
Marvex records public claims, sets out the material we checked them against, and states plainly what we found. Every entry carries its reasoning, not just its verdict.

What we do
A record you can follow, not just a verdict to accept.
Marvex checks claims made in public — by officials, on broadcast, and across social platforms — against documents, interviews, and records we can point to directly. We set the plain-language finding above the technical detail, so a general reader and a working journalist can both use the same entry.
- Every finding is paired with its evidence ledger.
- Revisions are logged with dates, never silently edited.
- Status markers are written in words, never colour alone.
- Standing subjects are indexed so patterns are easy to trace.

Our approach
Legibility of judgement, not just a verdict
- We show the documents and interviews behind each finding.
- We record when and why an assessment changed.
- We write for readers who want to check our working, not just our conclusion.
If a claim in your work needs a second look, we're glad to help.
