CAC registration vs trademark registration is the question that trips up more Nigerian founders than almost any other, because the two sound like they do the same job. They don’t. One makes your business legal. The other makes your brand yours.

In 2025, a baker in Ibadan registered her business name with the CAC in April. By July, the CAC had sent her a notice telling her to change it within six weeks, because another business already held a trademark on that name. She hadn’t copied anyone. She just didn’t know the trademark existed, and nothing in the CAC process had told her.

This guide explains the difference in plain English: what each registration actually gives you, what it doesn’t, and how to get both without learning the lesson the hard way.

CAC registration vs trademark registration: the short answer

CAC registration gives your business a legal identity. It’s what lets you open a bank account, sign contracts, pay tax, and operate lawfully. Trademark registration gives you the exclusive right to use your brand name, logo, or slogan for the goods and services you register it for, and the power to stop other people from using something confusingly similar.

Both matter, and neither replaces the other. Here’s how they compare side by side:

The rest of this guide unpacks that table, starting with what CAC registration really does for you.

What CAC registration gives you

CAC registration is what makes your business real in the eyes of the law. With a certificate in hand, you can open a corporate bank account, get a tax ID, sign contracts in the company’s name, and show investors that the business actually exists. It’s also not optional: CAMA treats carrying on business under a name that isn’t registered with the CAC as an offence.

When you apply, the CAC checks the name you want against its own register. If nobody on that register already has the same name or one that’s too similar, the name gets approved.

That’s the whole name check, and it’s worth reading that sentence twice. The CAC checks the CAC register. Which brings us to what the certificate doesn’t do.

What CAC registration doesn’t give you

A CAC certificate proves your company exists. It doesn’t prove you own the brand. Specifically:

• It doesn’t give you exclusive rights over the name. Outside the CAC register, anyone can still use a similar name, and nothing in your certificate stops them.
• It doesn’t cover your logo or slogan. Those aren’t registered at the CAC at all.
• It doesn’t stop your name from being challenged later. Even after approval, the name can be taken away or changed, which we’ll get to in a moment.
• It doesn’t reach beyond Nigeria. A CAC certificate means nothing in Kenya, Ghana, or anywhere else.

The challenge point is the one that catches people out. CAMA 2020 says the CAC shouldn’t register a name that’s identical to, or too close to, a registered trademark unless the trademark owner agrees. When a conflicting name does slip through, the CAC can direct the company to change it. That’s exactly what happened to the Ibadan baker.

CAMA 2020 also set up the Administrative Proceedings Committee, a tribunal-style body that hears objections to company names. One of the grounds is that the name infringes a registered trademark, or a mark the objector has built goodwill in. The CAC can also cancel a registered business name it finds deceptive or misleading. So a CAC certificate is a starting point, not a shield.

Why CAC approval doesn’t catch trademark conflicts

You might wonder why the CAC approved the baker’s name in the first place if a trademark already existed. The answer is that the two registers are separate. The CAC checks its own register of companies and business names. Trademarks live at the Trademarks Registry, and the CAC’s name approval doesn’t automatically cross-check it.

So a name can sail through CAC approval and still collide with someone’s trademark. When that happens, you’re the one who pays for it, through new signage, new packaging, a new domain, and the goodwill you built under a name you now have to drop.

Even big names run into this. KPMG Nigeria challenged the CAC’s registration of a company with a similar name, and the court held that the registration was improper and misleading under the law. If a firm that size has to go to court over it, a small business has very little room for error.

The fix is simple, though, and it starts with understanding what a trademark does.

What trademark registration gives you

A registered trademark gives you exclusive rights to your brand identity for the goods and services you registered it for. In practice, that gets you four things:

• The right to stop copycats. If someone uses a confusingly similar name or logo for similar goods or services, you have a legal basis to act against them.
• Coverage for your logo and slogan, not just your name.
• Standing to challenge a conflicting company name, the same route that worked against the baker’s name.
• An asset investors can see. When you raise money, a registered trademark shows the company owns its brand. Our fundraising documents checklist covers how investors check this.

To be fair, an unregistered brand isn’t completely unprotected. The law recognizes goodwill that you build through use. The catch is that you have to prove it, which takes time, evidence, and money. A registration is proof you can simply point to.

So do you need both?

Yes. They do different jobs, and the cleanest way to see it is this: a CAC certificate lets you run a business, and a trademark lets you keep the name you run it under. A trademark doesn’t give you the right to operate, and a CAC certificate doesn’t give you the right to the brand.

Founders who treat them as alternatives usually end up with one and a problem. Founders who treat them as a pair end up with a business that’s both legal and defensible. Here’s the order that works.

How to cover both, step by step

1. Search both registers before you commit to a name. Check the CAC portal for company names, and check the trademark register for marks. A trademark search takes a few working days, which is nothing compared with a rebrand.
2. Pick a name that clears both. If either search turns up something identical or close, choose a different name now, while changing it costs nothing.
3. Register the business with the CAC. If you plan to raise money, bring on co-founders, or scale, register as a Limited Company. Take a look at the  CAC Registration Documents Checklist
4. File your trademark in the company’s name, in the right classes for what you sell.
5. Put the dates in your calendar. That means CAC annual returns every year and trademark renewal when your term ends.

If you’re expanding beyond Nigeria, repeat step four in each new country, because protection doesn’t travel on its own.

Three myths that cost founders their brand names

“My CAC certificate proves I own the name.” It proves your company exists and that the name was available on the CAC register on the day you applied. It says nothing about who owns the brand.

“I registered a Business Name, so it’s covered.” A Business Name is also just a CAC registration. It can be objected to before the Administrative Proceedings Committee, and it gives you no exclusive rights over the name.

“I’ll trademark it once the business takes off.” This is the expensive one. The more your brand grows, the more it costs to change and the more attractive it is for someone else to register first. The cheapest time to file is before anyone is looking.

What to do next

If you’ve registered with the CAC but never filed a trademark, that’s the gap to close. Start with a search of the trademark register for your name and logo, before anything else. If it comes back clear, file. If it doesn’t, you’ve just saved yourself a rebrand.

Frequently asked questions

Does CAC registration protect my business name? Only in a limited way. It stops the CAC from registering an identical name on its own register, but it doesn’t give you exclusive rights to the name as a brand. Only a registered trademark does that.

What’s the difference between CAC registration and trademark registration? CAC registration makes your business a legal entity that can operate, bank, and contract. Trademark registration gives you the exclusive right to use your name, logo, or slogan for specific goods and services, and the power to enforce it.

Can someone register a trademark on a name I already registered with the CAC? Yes. CAC registration doesn’t block a trademark application, so if you haven’t filed, someone else can. That can put your name at risk, especially if they register the mark first.

What can I do if someone has already registered my brand name with the CAC? If you hold a registered trademark, or can show you’ve built goodwill in the name, you can object before the Administrative Proceedings Committee. Act quickly and get advice, because the position depends on the facts.

Should I file the trademark as an individual or in my company’s name? You can do either, but filing in your company’s name, with its certificate of incorporation, keeps ownership clean from the start, especially if you’ll raise money or sell the business later.

How long does trademark registration take in Nigeria? You can usually expect an acceptance decision within two to three weeks of filing if there’s no conflict. After that, the mark is published for opposition, and if nobody objects, the certificate is issued.

Does a Nigerian trademark protect me in other countries? No. Trademark protection is national, so every country you operate in needs its own filing.
