Registering a private company with the CIPC gives you a Memorandum of Incorporation (MOI). Many founders assume that is the governance box ticked. It isn’t. The MOI makes your company legally exist. It says very little about how you and your co-founders will actually deal with each other when money, power or commitment get tested.
Understanding the difference between a shareholders agreement and an MOI in South Africa isn’t about collecting two documents. It’s about knowing what each one is for, so you stop expecting one to do the other’s job.
The Short Answer: Two Documents, Two Different Jobs
Your MOI is the company’s public constitution. Your shareholders agreement is a private contract between the people who own it.
That one difference explains almost everything else: who can see each document, who it binds, what belongs in it, and which one wins when they disagree.
Why one is public and the other private
The MOI is lodged with the CIPC. Creditors, regulators, banks and prospective investors can all obtain it and rely on it. That is the point. Anyone dealing with the company needs to know how it is structured and who can bind it.
A shareholders agreement is a contract between named parties and stays confidential. That is why it is the right home for commercially sensitive terms: how the business will be valued if someone leaves, what happens in a deadlock, who funds the next round. These are matters between owners, and they don’t belong in a document anyone can request.
Why one is compulsory and the other is a choice
Every company must have an MOI. Without one, there is no company. A shareholders agreement is optional, so many founders never write one. That works while you are the only shareholder. The moment you bring in a partner, an employee with equity or an investor, you are relying on statutory defaults that were designed for every company, not for your specific deal.
Why the MOI Wins When the Two Conflict
Section 15(7) of the Companies Act allows shareholders agreements, but they must be consistent with the Act and the MOI. To the extent a clause conflicts, it is void.
The reasoning behind that rule is worth understanding. The MOI is public, and outsiders rely on it. If private side-deals could quietly override it, nobody dealing with the company could trust what the public record says. The hierarchy protects third parties, not just shareholders.
What this means in practice
- A conflicting clause fails, not the whole agreement. But finding out which clauses fail often means a dispute, and disputes tend to arrive at exactly the wrong moment: during an exit, a deadlock or a funding round.
- You cannot contract your way around the Act. Founders sometimes try to use a private agreement to dodge a statutory requirement. If a provision is meant to apply universally, a private arrangement won’t switch it off.
- Some protections work best when they appear in both places. A shareholders agreement binds only the people who signed it. If a protection also needs to bind the company itself, it may need to be reflected in the MOI too. This is a good reason to design the two documents together rather than separately.
What Each Document Should Actually Contain
The most common drafting mistake is putting a provision in the wrong document, or assuming the other document covers it. Think about it in terms of who the provision affects.
Put it in the MOI if it affects how the company deals with the world
- Share classes and their rights
- How directors are appointed and removed
- Decision-making thresholds, including special resolutions
- Procedures for shareholder meetings and voting
These are structural rules that outsiders may need to rely on, so they sit in the public document. Our Memorandum of Incorporation guide explains the statutory defaults and where you can customise them.
Put it in the shareholders agreement if it affects how owners deal with each other
- Tag-along and drag-along rights
- Pre-emptive rights and valuation methods on a transfer
- Vesting and what happens if a founder stops contributing
- Funding obligations and dividend policy
- Deadlock-breaking and dispute resolution
This is the “what if the relationship changes” layer. A standard CIPC MOI doesn’t address most of it. Without an agreement, you fall back on defaults that were never written with co-founders or venture investors in mind. Our article on pre-emptive rights and CIPC risks explains what goes wrong when founders try to squeeze private protections into the public filing.
Do You Need Both?
If you have more than one shareholder, almost certainly yes. They are two halves of one governance framework, not alternatives.
- Sole founder, no plans to bring anyone in: an MOI alone may be enough for now.
- Co-founders, partners or employees receiving equity: you need a shareholders agreement, ideally before shares are issued.
- Taking outside investment: investors will expect a properly aligned MOI and shareholders agreement, and will test them in due diligence.
Why timing matters
The best time to agree on exit terms is before anyone has a reason to disagree. Founders who negotiate valuation and departure rules while they still get along usually reach fairer outcomes than those who negotiate after a falling-out, when each side is protecting a position. Waiting until a dispute or an investor’s term sheet forces the issue leaves you with less leverage and higher legal costs.
If you’re still a solo founder, it’s worth knowing now what you will eventually need. Our startup legal requirements checklist is a good place to plan the order of things.
How Conflicts Creep In (and How to Avoid Them)
Conflicts between the two documents rarely come from bad faith. They come from drafting each one in isolation.
- Copied precedents. A clause lifted from another company’s agreement may rely on a different MOI, or on provisions that have since changed. Check every borrowed clause against your own MOI and the current Act.
- Inconsistent definitions. If “Shareholder”, “Fair Value” or “Business Day” means slightly different things in each document, you have created a dispute waiting to happen. Use the same definitions and cross-refer explicitly.
- Assumed coverage. Each document quietly assumes the other will deal with a scenario, so nobody does. Walk through the scenarios you care about (a founder leaves, an investor wants out, two directors disagree) and confirm which document answers each one.
A simple test: for every important right or obligation, ask who does this need to bind, and where does that person find it? If you can’t answer, the provision is probably in the wrong place or missing.
Putting This Into Practice
- Review your existing MOI against who your shareholders are today and where you expect the business to be in two or three years.
- List the relationship-specific terms you need: exits, transfers, vesting, funding, deadlock.
- Decide where each one belongs, using the public/private test above.
- Check for conflicts before anyone signs, and get a lawyer to review anything complex, such as an existing dispute, a significant investment or a sale of the business.
The point is to understand these decisions well enough to make them deliberately. PocketAdvisor’s Legal Toolkits are built around that idea: short explainer videos to understand the issues, workbooks to work through the decisions for your own business, and then professionally drafted South African documents, including an MOI and a shareholders agreement, to implement what you’ve decided. The templates are there to support your thinking, not replace it.
Frequently Asked Questions
Is it better to be a shareholder or a director?
They are different roles and not mutually exclusive. Directors manage the company and owe it fiduciary duties. Shareholders own equity and vote on major decisions. Many founders are both, but outside investors often prefer to be shareholders only, to avoid the duties and personal exposure that come with a directorship.
What is an MOI in corporate terms?
The Memorandum of Incorporation is the founding document registered with the CIPC that constitutes a South African company. It sets out the rules for internal management, share structure and director appointments, as required by the Companies Act. It is a public document that anyone can request from the CIPC.
Can you provide an example of a Memorandum of Incorporation?
The CIPC provides standard-form MOIs (CoR 15.1A to 15.1D) when you register, and these cover the statutory basics. A bespoke MOI adds customised provisions such as multiple share classes, amendment thresholds and director election procedures tailored to your business. Our MOI guide walks through the options.
What rights do majority shareholders have?
A majority shareholder typically controls ordinary resolutions, which need more than 50% support, such as appointing directors or declaring dividends, subject to what the MOI says. They cannot amend the MOI without meeting the special resolution threshold, and they cannot oppress minority shareholders contrary to the Companies Act. Protections for minority holders are best set out in both the MOI and the shareholders agreement so there is no uncertainty about control.
