Effect of Certificate of Incorporation in Nigerian Law: What Happens After Registration

The journey from idea to incorporated company ends at a precise legal moment. Not when the memorandum and articles of association are signed. Not when the application is filed at the Corporate Affairs Commission. Not when the filing fees are paid. The company comes into existence at the moment the Registrar-General issues the certificate of incorporation. That document, a single page bearing the company name, its registration number, and the date of incorporation, is one of the most consequential legal instruments in Nigerian commercial practice.

Everything that follows in a company’s legal life, every contract it signs, every asset it holds, every debt it owes, every lawsuit it brings or faces, rests on the foundation laid by that certificate. Understanding its legal effect is not merely academic. It is the gateway to every other topic in company law.

The Statutory Basis: Sections 41 and 42 of CAMA 2020

The legal consequences of registration are set out in sections 41 and 42 of CAMA 2020, which together constitute the foundational provisions on the effect of incorporation.

Section 41(1) provides that when the Commission is satisfied that the requirements of CAMA 2020 have been complied with in relation to registration, it shall register the company and issue a certificate of incorporation.¹ The use of the word “shall” is significant: once the Commission is satisfied that the statutory requirements have been met, it has no discretion to refuse registration. The issue of the certificate is a mandatory legal consequence of compliance.² This protects applicants from arbitrary refusals and ensures that the process is governed by law rather than administrative preference.

Section 41(2) provides that the certificate of incorporation shall be signed by the Registrar-General or some other officer of the Commission duly authorised by the Registrar-General.³ The certificate’s authenticity is therefore institutional rather than personal: it derives its force from the Commission’s statutory authority, not from the identity of the individual who signs it.

Section 41(3) is the first critical provision on evidentiary effect. It provides that the certificate of incorporation shall be conclusive evidence that all the requirements of the Act in respect of registration have been complied with.⁴ This is the conclusive evidence rule, and its practical importance is enormous.

Section 42 then sets out the substantive legal consequences that flow from the certificate. It provides that from the date of incorporation stated in the certificate, the subscribers to the memorandum and such other persons as may from time to time become members shall be a body corporate by the name contained in the memorandum, capable forthwith of exercising all the powers and functions of an incorporated company, including the power to hold land, and having perpetual succession and a common seal.⁵

Prima Facie Evidence or Conclusive Evidence?

A critical question in Nigerian company law, and one that has generated both academic commentary and judicial attention, is whether the certificate of incorporation constitutes prima facie evidence or conclusive evidence of compliance with registration requirements.

The position under CAMA 2020 represents a change from the position under earlier Nigerian legislation. Under CAMA 1990 and CAMA 2004, section 36(6) provided that the certificate of incorporation was “prima facie evidence” of compliance with the Act.⁶ Under the current CAMA 2020, section 41(3) upgrades this to “conclusive evidence.”⁷ This is a significant distinction with practical consequences.

Prima facie evidence means evidence that is sufficient to establish a fact unless contradicted or rebutted. A certificate described as prima facie evidence could be challenged: a party could adduce evidence to show that the requirements of the Act had not in fact been complied with, and the court could look behind the certificate. Conclusive evidence, by contrast, is evidence that the law treats as establishing a fact beyond contradiction, regardless of what other evidence might suggest. Once issued, a certificate described as conclusive evidence cannot be undermined by showing that the underlying requirements were not met.⁸

This upgrade from prima facie to conclusive evidence under CAMA 2020 was deliberate. It strengthens the certainty of title and commercial reliance on the certificate. A party dealing with an incorporated company can rely absolutely on the fact that the company exists as a legal entity from the date on the certificate, without any risk that the company’s existence could later be challenged on the ground of some procedural irregularity in the registration process.⁹

However, the conclusive evidence rule has a limit. Section 41(7) of CAMA 2020 provides that the Commission may withdraw, cancel, or revoke a certificate of incorporation where it is discovered that the certificate was fraudulently, unlawfully, or improperly procured.¹⁰ This is an important safety valve. The conclusive evidence rule prevents third parties from using procedural irregularities to undermine a company’s existence, but it does not protect a company whose certificate was obtained through fraud. Where the Commission exercises this revocation power, it must do so lawfully and in accordance with the principles of natural justice.¹¹

Transition from Association to Body Corporate

The most fundamental effect of the certificate is the transformation it effects in the legal status of the subscribers and the entity they have created. Section 42(1) of CAMA 2020 is explicit: from the date of incorporation stated in the certificate, the subscribers to the memorandum and any subsequent members shall be a body corporate.¹²

Before that moment, the subscribers are merely an association of individuals. They may have signed the memorandum, they may have agreed on the company’s name and objects, they may have made pre-incorporation contracts through their promoters, but they have no collective legal personality. They cannot collectively own property, enter contracts, sue, or be sued in the company’s name.

After the certificate, they, together with any subsequent members, constitute a body corporate: a legal person in its own right, distinct from each of them individually. This is the doctrine of corporate personality in Nigerian law in its practical application. The Salomon principle, that a company is at law a different person altogether from its subscribers,¹³ moves from abstract doctrine to concrete legal reality at the moment the certificate is issued.

In Abakaliki LGC v Abakaliki Rice Mills Owners Enterprises,¹⁴ the court confirmed that a company duly incorporated under Nigerian law must be treated as having a separate legal existence from the date of incorporation stated in its certificate, and that the certificate is the definitive evidence of that existence. The company’s separate personality begins on that date and continues until the company is dissolved.¹⁵

Specific Legal Attributes Conferred by Section 42

Section 42(1) of CAMA 2020 identifies five specific legal attributes that the body corporate acquires upon incorporation.

Capacity to Exercise Corporate Powers

The body corporate is capable forthwith of exercising all the powers and functions of an incorporated company.¹⁶ Section 43 of CAMA 2020 reinforces this by providing that, unless the memorandum specifically restricts the company’s objects, the company shall be deemed to have unlimited capacity to carry on any lawful business.¹⁷ This abolishes the old ultra vires doctrine for third parties: a company incorporated under CAMA 2020 with an unrestricted objects clause has the same legal capacity as a natural person of full age and capacity. It may sue, be sued, contract, own property, take on liabilities, and do everything that a legal person is capable of doing.

Power to Hold Land

The body corporate has the power to hold land from the moment of incorporation.¹⁸ This is practically significant in a jurisdiction where the Land Use Act 1978 vests all land in the Governor of each State. A company wishing to hold a right of occupancy over land must be a legal person capable of holding such rights. The certificate of incorporation confers that capacity immediately. Without it, there is no legal entity to which a right of occupancy can be granted.

Perpetual Succession

The body corporate has perpetual succession.¹⁹ This means the company continues to exist regardless of changes in its membership or the death, bankruptcy, or incapacity of any individual member, director, or officer. The company is not dissolved by the death of its sole shareholder, by the retirement of all its directors, or by any change in its human composition. It continues until it is formally wound up in accordance with CAMA 2020.

Perpetual succession is one of the defining commercial advantages of the incorporated company over the partnership and the sole proprietorship. A sole proprietorship dies with its owner. A partnership may dissolve on the death of a partner. A company, once incorporated, outlives its founders and continues to be owned and managed by whoever holds its shares and directs its affairs at any given time.²⁰

Common Seal

Section 42(1) also confers on the body corporate a common seal.²¹ However, it is important to note immediately that under CAMA 2020, the common seal is now optional. Section 98 of CAMA 2020 provides that a company need not have a common seal.²² Where a company does not have a common seal, it may authenticate documents and execute deeds through the signatures of authorised officers. Where it does have a common seal, the rules for its use and authentication apply.

The common seal, where used, is the company’s official stamp of authority. It functions as the equivalent of a signature for a natural person: its impression on a document, properly attested, confirms that the company has authorised and executed that document.

Liability of Members to Contribute

Section 42(1) preserves the liability of members to contribute to the company in the event of its being wound up, in accordance with the memorandum.²³ For a company limited by shares, this means each member is liable only to the extent of any amount unpaid on the shares held by that member. Once shares are fully paid, the member bears no further liability, however large the company’s debts may be. This is the limited liability that makes the incorporated company such an attractive vehicle for commercial activity.

The Certificate and Third Parties

The conclusive evidence rule under section 41(3) of CAMA 2020 is designed primarily to protect third parties dealing with companies. A counterparty who enters into a significant commercial transaction with a company registered at the CAC can rely on the certificate as proof of the company’s existence without the need to investigate whether the registration process was conducted with perfect regularity.²⁴

This protection interacts with section 104 of CAMA 2020, which provides for the abolition of constructive notice of registered documents. Under the old doctrine of constructive notice, any person dealing with a company was deemed to have notice of every document registered at the CAC. Section 104 abolishes this doctrine, so that a person dealing with a company is not affected by notice of the contents of any document merely by virtue of the fact that the document is registered.²⁵ The combined effect of section 41(3) and section 104 is to create a significantly more commercial-friendly environment: third parties can deal confidently with incorporated companies without elaborate investigations into their registered documents.

Post-Incorporation Steps

The issuance of the certificate of incorporation is not the end of the process of establishing a company in practice. Several important steps typically follow immediately upon incorporation.

The company must open a corporate bank account in its own name. Under current banking practice in Nigeria, this requires the certificate of incorporation, the MEMART, a board resolution, identification documents for the directors, and the company’s Tax Identification Number, which under the Nigeria Tax Act 2025 is automatically the company’s RC Number from the date of incorporation.²⁶

The company should hold its first board meeting to formally appoint directors, open bank accounts, adopt the company’s seal if it chooses to have one, ratify any pre-incorporation contracts under section 96 of CAMA 2020, and take any other preliminary steps required for business commencement.²⁷

The company should also ensure compliance with any sector-specific regulatory requirements applicable to its proposed business. A company intending to operate as a financial institution must be licensed by the Central Bank of Nigeria. A company intending to operate in the capital market must be licensed by the Securities and Exchange Commission. The certificate of incorporation establishes the company as a legal person but does not authorise it to carry on any business that requires a specific regulatory licence.²⁸

CAMA 2020 Highlight: Key Changes to the Effect of Registration

Conclusive evidence (section 41(3)). CAMA 2020 upgrades the evidentiary effect of the certificate of incorporation from “prima facie evidence” (under the 1990/2004 Act) to “conclusive evidence.” This means the certificate can no longer be challenged on the ground that registration requirements were not met. Third parties dealing with the company are fully protected.

Revocation power (section 41(7)). Notwithstanding the conclusive evidence rule, the Commission may now revoke a certificate obtained by fraud, unlawfully, or improperly. This revocation power is new in CAMA 2020 and has no equivalent in the old Act.

Common seal now optional (section 98). The previous automatic conferral of a common seal is now conditional: a company may choose to have a common seal, but is no longer required to do so. Documents may be authenticated by authorised officer signatures under section 101.

Unlimited capacity by default (section 43). Unless the memorandum specifically restricts the company’s objects, the company has unlimited capacity to carry on any lawful business. This effectively abolishes the ultra vires doctrine for third parties and removes the need for extensive and artificially broad objects clauses.

Electronic authentication (section 101). An electronic signature satisfies the requirement for signing under CAMA 2020, and documents authenticated electronically have the same legal effect as paper originals.

RC Number as TIN. Under the Nigeria Tax Act 2025, the company’s CAC Registration Number automatically serves as its Tax Identification Number from the date of incorporation, eliminating the need for a separate registration with the Nigeria Revenue Service.
