Here's a question worth asking yourself right now, honestly: if someone walked into your office today, found your company seal, and pressed it onto a document you'd never seen, how long would it take you to even notice? For a lot of Nigerian business owners, the honest answer is uncomfortable — because that heavy, metal, jaw-like device sitting in a desk drawer somewhere doesn't get treated with anywhere near the seriousness it deserves. It's often filed away like a stapler. It shouldn't be.

First, Let's Be Precise About What We're Actually Talking About

It's worth separating two things that get confused constantly, even by people who should know better. An ink stamp — the kind used to mark "Received," date documents, or print an address on routine paperwork — is a working tool. If it's misused, the damage is usually limited and easy to spot. A company common seal is a different category of object entirely. When it's pressed onto a document alongside proper signatures, it functions as a physical declaration that the company itself, not just an individual employee, has bound itself to whatever that document says.

What Nigerian Law Actually Says (And What Changed in 2020)

Here's something that surprises a lot of business owners: since the Companies and Allied Matters Act (CAMA) 2020, having a common seal is no longer legally mandatory. Under Section 98, it's now optional — a company can choose not to have one at all. Sections 101 through 103 lay out alternative ways to properly execute a document: signature by a director and the company secretary, by at least two directors, or by a single director in the presence of an attesting witness. Any of these carries the same legal weight as if the document had been sealed.

But here's the part that matters for this conversation: plenty of Nigerian companies still choose to keep and use a common seal — for the added weight it carries with banks, legal counterparties, and courts, and because a properly engraved seal is harder to casually forge than a signature alone. And when a company does have one, the law hasn't gotten any more forgiving about who's authorised to use it. A document bearing your genuine company seal is difficult to disown later, regardless of who in your office actually pressed it down. The seal doesn't ask permission before it convinces a judge.

How This Actually Goes Wrong

The scenario is rarely dramatic. You're travelling, or simply out of the office for a few days handling something else entirely. Back at base, someone needs a document actioned urgently — a supplier agreement, a lease, an authorisation letter. Rather than waiting for you, an overeager staff member decides the sensible thing is to "just handle it," retrieves the seal from an unlocked drawer, and presses it onto a document you've never laid eyes on. By the time you're back, the company is already, legally, a party to whatever that paper says.

It doesn't require dishonesty to go wrong this way — just casualness. And once a document carries your company's genuine seal, proving in court that it was unauthorised is a genuinely difficult fight, not a quick clarification.

Keeping It Under Proper Control

None of the fixes here are complicated. They just require treating the seal like what it actually is:

  • Store it like something valuable — a locked cabinet or safe, not a shared drawer everyone in the office has access to.
  • Apply a two-person rule — the seal only comes out when at least two authorised people (typically two directors, or a director and the company secretary) are present, matching how CAMA itself expects deeds to be executed.
  • Keep a seal register — every time it's used, log the date, the document, who authorised it, and who witnessed it. A simple habit that turns "he said, she said" into an actual paper trail.
  • Limit who even knows where it's kept — the fewer people who can casually access it, the fewer opportunities for a costly mistake.

Where a Properly Made Seal Actually Helps You

One detail worth knowing: the quality of the seal itself is part of your protection. A precisely engraved Corporate Pocket Seal or Corporate Table Seal — with your company's exact registered name and RC number, cut cleanly and consistently — is genuinely harder to replicate or forge convincingly than a cheaply made one. If you're due for a replacement, or you've never actually had yours professionally made, that's worth sorting out alongside tightening who has access to it. Good custody habits and a well-made seal work together, not separately.

Running a business in Nigeria already means managing enough real risk. An unsecured company seal shouldn't be one you're carrying without realising it.
