HOW TO USE CAC PUBLIC SEARCH FOR YOUR BUSINESS REGISTRATION
A Comprehensive Legal and Practical Guide for Nigerian Entrepreneurs, Startups, and Professionals
Understanding how to use CAC Public Search for your business registration is no longer optional for anyone serious about doing business in Nigeria. Whether you are a startup founder validating a business name, an investor conducting due diligence, a professional entering a partnership, or a business owner seeking regulatory compliance, CAC Public Search is a critical legal tool that directly affects the validity, safety, and enforceability of business transactions.
In practice, a significant number of business disputes, failed registrations, trademark conflicts, and even fraud cases in Nigeria arise because parties failed to properly search or verify records at the Corporate Affairs Commission (CAC) before proceeding. Many entrepreneurs assume that because a business name is in use on social media or has a website, it is legally registered. This assumption is frequently wrong—and costly.
This article provides a highly comprehensive, authoritative, and SEO-optimized guide on how to use CAC Public Search for your business registration, written from the perspective of Nigerian legal practice. It explains what CAC Public Search is, the legal framework behind it, step-by-step procedures, practical use cases, common mistakes, what lawyers and courts care about, and answers frequently asked questions based on real business scenarios.
What Is CAC Public Search?
CAC Public Search is an official online search facility provided by the Corporate Affairs Commission that allows members of the public to verify information about registered business names, companies, and incorporated trustees in Nigeria.
Through CAC Public Search, users can confirm whether a business name is available, already registered, reserved, or conflicts with existing entities. It also allows access to basic information about registered entities, including registered names, registration numbers, and status.
From a legal standpoint, CAC Public Search is a pre-registration and post-registration due diligence tool. It helps prevent identity conflicts, fraud, and regulatory breaches.
The Legal Framework Governing CAC and Public Search in Nigeria
The Companies and Allied Matters Act (CAMA)
The authority of the CAC, including its power to maintain and make company records accessible, is derived from the Companies and Allied Matters Act. CAMA establishes the CAC as the statutory body responsible for business registration and regulation in Nigeria.
CAMA mandates the Commission to keep registers of companies and business names and make them available for public inspection. This is the legal basis for CAC Public Search.
Transparency and Public Access to Corporate Records
The rationale behind CAC Public Search is transparency. Nigerian law recognises that third parties are entitled to rely on corporate records when entering into business relationships.
This principle aligns with broader commercial law practice, where public registers are relied upon to determine legal personality, ownership, and authority.
Why CAC Public Search Is Crucial Before Business Registration
Before registering any business name or company in Nigeria, CAC Public Search helps you determine:
• Whether your proposed name is already taken
• Whether it is deceptively similar to an existing name
• Whether it may conflict with restricted or prohibited names
• Whether it exposes you to legal action after registration
From a lawyer’s perspective, failing to conduct a proper CAC search is one of the most common and avoidable mistakes Nigerian entrepreneurs make.
Step-by-Step Guide: How to Use CAC Public Search
Step 1: Access the CAC Public Search Portal
The CAC Public Search is accessed through the official CAC online platform. You do not need to create a full registration account just to perform a basic public search.
This accessibility is intentional, as the law encourages public verification of business information.
Step 2: Choose the Appropriate Search Category
CAC Public Search allows you to search under different categories, including:
• Business Names
• Companies (Limited by Shares, Limited by Guarantee, Unlimited)
• Incorporated Trustees
Choosing the correct category is important. Many users mistakenly search for companies under business names or vice versa, leading to incorrect conclusions.
Step 3: Enter the Proposed or Existing Business Name
When entering a name, it is advisable to try multiple variations. Nigerian registration practice treats names as conflicting not only when they are identical, but also when they are confusingly similar.
For example, “Prime Tech Solutions” may conflict with “Prime Technologies Nigeria Ltd,” depending on context.
Step 4: Review Search Results Carefully
CAC Public Search results typically show whether a name is:
• Available
• Already registered
• Reserved
• Restricted
A common misunderstanding is assuming that because a name appears slightly different, it is safe to use. In practice, the CAC may still reject such names during registration.
Lawyer’s View: What Usually Goes Wrong With CAC Searches
In real practice, clients often rely on incomplete searches or screenshots shared by third parties. Others assume that because a name is not visible on Google, it is available at CAC.
Courts and regulators care about official records, not online presence. If a name conflicts with an existing registered entity, the later registrant may be compelled to change its name, rebrand, or face legal action—even after years of operation.
CAC Public Search and Business Name Reservation
CAC Public Search plays a critical role in name reservation, which is the process of temporarily securing a business name before full registration.
Name reservation does not create ownership; it merely prevents others from registering the same name during the reservation period. Many disputes arise when entrepreneurs mistakenly believe reservation equals registration.
Using CAC Public Search for Due Diligence and Verification
Beyond registration, CAC Public Search is widely used for:
• Verifying business partners
• Confirming directors or proprietors
• Checking company status before investment
• Detecting fake or unregistered businesses
Investors and professionals routinely rely on CAC search results before committing funds or signing agreements.
Relationship Between CAC Search and Intellectual Property Protection
While CAC registration establishes business identity, it does not automatically confer intellectual property rights. Many business owners wrongly assume that registering a name at CAC protects them from brand infringement.
In reality, trademark protection is governed by the Trademarks Act and administered by the Trademarks, Patents and Designs Registry, while copyright matters are overseen by the Nigerian Copyright Commission.
A name cleared at CAC may still infringe an existing trademark. This is a frequent source of litigation and forced rebranding.
What Nigerian Law Says About Business Identity and Regulation
CAMA reinforces the importance of proper registration and disclosure. Nigerian courts have repeatedly held that unregistered or improperly registered businesses lack full legal standing to enforce rights.
This aligns with the constitutional framework on property and commercial regulation. Section 44 of the Constitution of the Federal Republic of Nigeria 1999 (as amended) provides:
“No movable property or any interest in an immovable property shall be compulsorily taken possession of except in the manner and for the purposes prescribed by law.”
Business identity, though intangible, is treated as a valuable commercial interest protected by law only when properly registered.
Common Mistakes When Using CAC Public Search
Some of the most frequent errors include:
• Searching only exact spellings
• Ignoring similar or confusing names
• Assuming availability equals approval
• Skipping trademark searches
• Using third-party or unofficial platforms
These mistakes often result in rejection, legal disputes, or costly rebranding.
How Much Does CAC Public Search Cost?
Basic CAC Public Search is generally free. However, obtaining certified extracts or detailed company information may attract statutory fees.
Professional fees may also apply where lawyers or consultants conduct comprehensive due diligence on your behalf.
How Long Does CAC Name Clearance Take?
Search results are usually instantaneous. However, name reservation approval may take additional processing time, depending on volume and compliance with naming rules.
Enforcement, Disputes, and Regulatory Action
Where a business name conflicts with existing records, the CAC has statutory power to direct a change of name. Courts support this authority and rarely excuse ignorance of the register.
This is why CAC Public Search is treated as a mandatory compliance step, not a formality.
