The Memorandum of Incorporation: The Document Every Company Has and Almost Nobody Reads

The Memorandum of Incorporation is, legally, the single most important document a company has — more important, in a real sense, than the CIPC registration certificate itself, because it is the MOI that sets the actual rules the company runs by. And it is also the document new business owners are least likely to have read, because the default version is applied automatically and nobody has to think about it unless something goes wrong.

What the MOI actually is

Every company incorporated under the Companies Act 71 of 2008 has an MOI — it is the modern replacement for what used to be a separate Memorandum and Articles of Association under the old 1973 Act, now combined into one governing document. The MOI sets out the rules for how the company is run: the powers and limitations of directors, how shares work, how decisions get made, and anything else the founders want to specify beyond what the Act itself provides as a baseline.

Crucially, the Companies Act is largely a default framework — many of its provisions apply "unless the MOI provides otherwise". This means the MOI is not just a formality sitting in a CIPC file; it is where a company can genuinely customise how it operates, within the boundaries the Act allows.

The standard MOI: what you get by default

When a private company is registered without submitting a custom MOI, CIPC automatically applies the short-form standard MOI — form CoR15.1A. A longer standard form, CoR15.1B, also exists and provides more detailed default rules while still following the Act's standard framework rather than genuinely bespoke provisions.

For a large number of small, straightforward companies — particularly a single founder or a small group of co-founders with no outside investors and a simple, shared understanding of how the business runs — the standard MOI is genuinely fine. It is not a compromise document; it reflects the Act's own baseline rules, which are reasonably sensible defaults for an uncomplicated company.

When a customised MOI earns its cost

The standard form starts to strain once a company's ownership or governance is not simple. Situations where a custom MOI is genuinely worth drafting:

• Multiple shareholders with different roles or contributions. If one founder is putting in capital and another is contributing sweat equity and expertise, the standard MOI's default rules on things like director appointment rights or dividend decisions may not reflect what was actually agreed.
• An outside investor is coming in. Investors very commonly require specific provisions — rights to appoint a director, pre-emptive rights if new shares are issued, restrictions on how existing shareholders can transfer their shares — that the standard MOI simply does not include. A funding round is one of the most common triggers for moving from standard to custom.
• You want to restrict who shares can be transferred to. A standard MOI does not automatically stop a shareholder from selling their stake to an outsider the other founders don't want involved — if keeping ownership within a defined group matters, that needs to be written into a customised MOI (or a separate shareholders' agreement working alongside it).
• You want a formal mechanism for resolving deadlocks or disputes between shareholders — particularly relevant for a 50/50 company, where the standard form has no built-in tie-breaker if the two owners genuinely disagree.
• Specific rules around director powers beyond the Act's defaults — requiring board approval above a certain transaction value, for instance, rather than leaving that entirely to directors' discretion.

How amending it actually works

Moving from the standard MOI to a customised one, or amending an existing custom MOI, follows the same process our earlier guide to changing company details at CIPC covers for a company name change: shareholders pass a special resolution, and the company files a Notice of Amendment (form CoR15.2) with CIPC — R80 for a minor amendment or R250 for any other, per CIPC's own published fee schedule. You can replace a standard MOI with a custom one at any point in a company's life; it does not have to happen at incorporation, though doing it before a dispute arises is considerably easier than doing it during one.

Custom MOI vs shareholders' agreement: not the same thing

These are often confused, and both matter: the MOI is a public, filed document that governs the company itself and is enforceable as such — anyone dealing with the company can rely on what it says. A shareholders' agreement is a private contract between the specific shareholders, covering things they may not want on the public record (financial arrangements, personal understandings) but which does not bind the company itself or third parties the way the MOI does. Well-advised companies with more than one shareholder frequently have both, each doing a different job — and getting advice on how the two should work together, rather than treating them as substitutes for each other, is exactly the kind of decision worth a proper consultation rather than a template downloaded and adapted alone.

What this means practically for a new company

If you are a single founder, or a small group of co-founders with a genuinely simple, shared understanding of how the business runs, the standard MOI CIPC applies automatically is a reasonable starting point — do not feel pressured into an expensive custom document you do not yet need. But the moment any of the triggers above become real — an investor, a disagreement about roles, a desire to restrict who shares can be sold to — that is the point to get a company secretary or attorney to draft a custom MOI properly, rather than continue operating on the standard form's defaults and hoping they happen to match what everyone actually intended.

Sources: the Companies Act 71 of 2008's framework for the Memorandum of Incorporation as the company's primary governing document, CIPC's standard MOI forms (CoR15.1A short-form, CoR15.1B long-form, automatically applied to a private company unless a custom MOI is submitted), and the CoR15.2 amendment process and fees (R80 minor / R250 other) already confirmed from CIPC's published fee schedule elsewhere in this series. This is general information, not legal advice — drafting or amending an MOI for anything beyond the simplest company should involve a company secretary or attorney.

A worked example: when standard stopped being enough

Two friends register a company on the standard MOI, each holding 50%, and run the business together for two years without issue — the standard form works fine because they agree on everything. Then one wants to bring in an external investor to fund expansion. The investor’s term sheet requires: a right to appoint one director to the board, a veto over any new share issuance that would dilute their stake without consent, and pre-emptive rights if either founder wants to sell shares later. None of this exists in the standard MOI — it has to be built in through a customised one, drafted and filed via CoR15.2 before the investment can actually close on the terms the investor wants. This is one of the most common real-world triggers for the standard-to-custom move: the MOI that was perfectly adequate for two aligned founders becomes inadequate the moment a third party with its own specific requirements enters the picture.

Frequently asked

Can I switch from the long-form standard MOI (CoR15.1B) to a fully custom one later, or does it have to be CoR15.1A first? Either standard form — short (CoR15.1A) or long (CoR15.1B) — can be replaced with a custom MOI at any point via the same CoR15.2 amendment process. There is no requirement to start on the short form specifically.

Does a non-profit company have different standard MOI options? Yes — CIPC provides separate standard MOI forms specifically for non-profit companies (short and long forms, both with and without members), distinct from the private-company forms this article focuses on. A non-profit’s governance needs differ enough from a trading company’s that the Act treats them separately.

How much does drafting a genuinely custom MOI typically cost, beyond the CIPC filing fee? The CoR15.2 filing fee itself is modest (R80–R250), but the real cost of a custom MOI is usually the professional drafting — an attorney or company secretary’s time to actually write provisions that reflect your specific arrangement properly. This varies considerably by complexity and is worth getting a quote for rather than assuming a fixed number.

If shareholders disagree about amending the MOI, what happens? Amending the MOI requires a special resolution, meaning a defined majority of shareholders must agree — exactly the kind of situation where a well-drafted dispute-resolution mechanism in the existing MOI (or a shareholders’ agreement) earns its keep, since without one, a genuine deadlock over changing the company’s own rules has no built-in way to resolve itself.

Is the MOI publicly available, or private? The MOI is filed with CIPC and is a public document — anyone can obtain a company’s MOI through a CIPC search. This is part of why sensitive commercial arrangements between shareholders are often kept in a separate, private shareholders’ agreement instead of written directly into the MOI.
