Share transfer restrictions are among the most consequential provisions in any shareholders agreement. They determine who may become a shareholder in the company, on what terms shareholders may exit, and how the remaining shareholders are protected when ownership changes hands. Without carefully drafted transfer restrictions, the only limits on a sale are the ones in the company's MOI — and those may not give the other shareholders a right to buy first, or any real say over who joins them, even if the buyer is a competitor.
Under the Companies Act 71 of 2008, a private company must, by law, restrict the transferability of its shares in its Memorandum of Incorporation (MOI) — this is one of the defining features of a private company under section 8(2)(b). A shareholders agreement builds on that mandatory MOI restriction with additional contractual machinery — pre-emptive rights, rights of first refusal, lock-in periods, drag-along rights, and tag-along rights — that governs the entire lifecycle of share ownership.
This guide explains each mechanism in detail, how they interact with B-BBEE requirements, what happens when transfers occur involuntarily through death or insolvency, and the practical steps involved in transferring shares under a shareholders agreement.
Why Restrict Share Transfers?
The shareholders of a private company typically choose one another carefully. They share a business vision, complementary skills, and mutual trust. Transfer restrictions preserve that carefully chosen composition by ensuring no unwanted third party can acquire shares without the existing shareholders having a meaningful say. The key objectives of transfer restriction provisions are:
1. Control Who Becomes a Shareholder
A private company is not listed on a public exchange. Shareholders do not want to find themselves in business with a stranger — or worse, a competitor — who has purchased shares from a departing shareholder without any consent process. Pre-emptive rights and rights of first refusal ensure existing shareholders have the opportunity to acquire any shares before they reach the open market.
2. Maintain B-BBEE Compliance
Companies in South Africa that rely on their B-BBEE ownership level for tenders, licences, or contracts must prevent the BEE-qualifying shareholder from simply selling their shares and eliminating the company's empowerment credentials. Lock-in provisions and mandatory replacement requirements address this directly.
3. Protect Minority Shareholders
If a majority shareholder sells to a third party without the minority having any exit right, the minority is suddenly locked into a company with an unknown majority shareholder they never agreed to. Tag-along rights solve this by giving the minority the right to exit on the same terms as the majority.
4. Provide an Orderly Exit Mechanism
Without defined exit mechanisms, a shareholder who wishes to leave has no clear path. Transfer restriction provisions — particularly pre-emptive rights — create an orderly, price-determined process that allows exits without destroying the business or creating deadlock.
Pre-Emptive Rights (Right of First Offer)
"Pre-emptive right" is a broad label for any right that gives existing shareholders priority when shares change hands. On a transfer it usually takes one of two forms: a right of first offer (covered here) or a right of first refusal (covered in the next section). They work differently, so the agreement should define the one it uses and stick to it. Under a right of first offer, a shareholder who wishes to sell must offer the shares to the existing shareholders first, before approaching any third party. It is a common transfer restriction in South African shareholders agreements.
Do not confuse this with the statutory pre-emptive right in section 39 of the Companies Act. Section 39 gives the shareholders of a private company a default right to be offered certain new shares the company issues, in proportion to their holdings. The MOI may limit or exclude that right, and it has exceptions. A transfer pre-emption right deals with a different event — an existing shareholder selling shares they already hold — and it exists only if the MOI or the shareholders agreement creates it.
How Pre-Emptive Rights Work
Notice by Selling Shareholder
The shareholder wishing to sell gives written notice to the remaining shareholders (and usually the company), stating the number of shares they wish to sell and the price at which they are offering them.
Exercise Period
The remaining shareholders have a defined period — typically 20 to 30 business days — to elect to purchase the offered shares. The agreement specifies whether elections must be in writing and how they are communicated.
Price Mechanism
The price is typically set by the selling shareholder in the notice. Some agreements use a formula — net asset value, earnings multiple, or independent valuation — to prevent an artificially inflated price from frustrating the right.
Pro-Rata or Equal Allocation
If multiple shareholders elect to purchase, the agreement must specify whether the offered shares are allocated pro-rata to their existing holdings or in equal portions. Pro-rata allocation is most common as it maintains relative ownership percentages.
Third-Party Window
If the pre-emptive right is not fully exercised within the exercise period, the selling shareholder may approach third parties — but typically only on terms no more favourable than those offered to existing shareholders, and only for a limited further period (e.g. 60 days).
SA Court Approach
South African courts generally hold shareholders to the transfer terms they agreed. A shareholder who bypasses the pre-emptive process — for example, by transferring shares directly to a third party without first offering them to existing shareholders — may face an interdict, a damages claim or an order undoing the transfer. But a transfer is not automatically void just because the shareholders agreement was breached. The outcome depends on the wording of the agreement and the MOI, whether the buyer has already been registered, and the applicable law. State the consequence of non-compliance in the agreement, and repeat the restriction in the MOI so that the company itself can act on it.
Right of First Refusal (ROFR)
The right of first refusal differs from the right of first offer in a critical way: it is triggered not by the selling shareholder's desire to sell, but by an actual third-party offer. The selling shareholder first obtains a bona fide offer from a third party, then must give the existing shareholders the opportunity to purchase on the same terms before accepting that offer.
Right of First Offer
- Seller sets the price — simpler and faster process
- No need to find a third-party buyer first
- Price may be unilaterally set high to frustrate the right
- No market discovery — price not tested against willing buyers
Right of First Refusal
- Price is market-tested — third party establishes fair value
- Existing shareholders can match a bona fide offer — arguably fairer
- Seller must first find a third-party buyer — slower and more complex
- Third-party buyers may be deterred by the matching right
Under a ROFR, once the selling shareholder receives a third-party offer, they must give notice to the remaining shareholders disclosing the full terms of the offer — price, payment terms, and any conditions. The existing shareholders typically have 20 to 30 business days to elect to purchase on those exact terms. If they decline or fail to respond, the seller may proceed with the third party on no more favourable terms than those disclosed.
Lock-In Periods
A lock-in period is a provision that prohibits a shareholder from disposing of any shares for a specified period — typically one to five years from the date of the shareholders agreement. During the lock-in, the shareholder cannot transfer, cede, pledge, or otherwise encumber their shares, regardless of whether other shareholders would exercise their pre-emptive rights.
Common Contexts for Lock-In Provisions
B-BBEE Transactions
The B-BBEE Codes of Good Practice do not contain a general rule that a black shareholder must hold shares for three or five years before the ownership counts. Ownership is measured under the code that applies to the company, by looking at the voting rights, economic interest and net value that black participants actually hold. A company that relies on its ownership score may still want a lock-in for commercial reasons — to keep its empowerment partner in place — but the period is a negotiated term. A lock-in does not by itself prove that the ownership is genuine.
Founder Agreements and Investor Agreements
Investors — particularly venture capital or private equity investors — routinely insist on founder lock-in periods to ensure the founders remain committed to the business after the investment is made. Typical founder lock-in periods range from two to four years, often with graduated vesting — for example, 25% of shares becoming freely transferable per year.
Permitted Transfers During Lock-In
Even during a lock-in period, certain transfers are typically permitted to allow for legitimate corporate restructuring and estate planning:
- Transfers to a wholly-owned subsidiary of the transferring shareholder (with an obligation to re-transfer if the subsidiary is no longer wholly owned)
- Transfers into a family trust for estate planning purposes, provided the trust meets the eligibility criteria set out in the agreement
- Transfers between companies within the same group of companies
- Transfers required by law (e.g., pursuant to a court order)
Condition: Deed of Adherence Required
Any permitted transferee during the lock-in period — including subsidiaries and family trusts — must execute a deed of adherence binding them to the full terms of the shareholders agreement. This prevents a transferring shareholder from using the permitted transfer mechanism to effectively circumvent the lock-in by transferring control of their holding entity.
Drag-Along Rights
A drag-along right (sometimes called a "bring-along" right) entitles a majority shareholder to compel the remaining minority shareholders to sell their shares to a third-party purchaser on the same terms and at the same price per share. In other words, if the majority finds a buyer willing to acquire 100% of the company, the majority can "drag" the minority into the sale. A drag-along is a contractual right, not an automatic statutory one: it exists only if the shareholders agreement (or the MOI) provides for it, and the qualifying majority is whatever the parties agree — often more than 50% or 75% of the shares.
How Drag-Along Rights Work
Triggering Event
A third party makes a bona fide offer for 100% of the company's shares (or all shares the majority can procure), and the majority shareholder(s) holding the requisite percentage accept the offer.
Drag Notice
The majority serves a written drag notice on the minority shareholders specifying the identity of the buyer, the price per share, payment terms, and the proposed completion date.
Minority Obligation
Upon receipt of the drag notice, the minority shareholders are obliged to sell their shares to the third party on the same terms and at the same price per share. If the drag notice complies with the agreement, they cannot hold out for a higher price.
Completion
All shareholders complete the sale simultaneously. The buyer acquires 100% of the company in a single clean transaction, which is precisely the outcome that makes the company attractive to serious buyers.
Minority Protection Under Drag-Along
While drag-along rights can feel coercive to minority shareholders, a well-drafted clause contains an important protection: the minority must receive the same price per share and the same terms as the majority. The clause should say how equal treatment works where there are different share classes, where part of the price is not paid in cash, and how far the minority must give warranties. It should also deal with side arrangements. A genuine salary for a majority shareholder who stays on to work for the buyer is not automatically disguised sale consideration, but undisclosed benefits that are really part of the price may give the minority grounds to challenge the drag. Many drag-along clauses simply use the genuine third-party price; others add a price floor or an independent valuation. Whichever is chosen, a contractual price does not exclude the remedies the Companies Act gives against unfairly prejudicial conduct.
Tag-Along Rights (Co-Sale Rights)
Tag-along rights are the mirror image of drag-along rights. Where a drag-along compels the minority to participate in a sale, a tag-along entitles the minority to participate in a sale being made by the majority. If a majority shareholder proposes to sell their shares to a third party, the minority shareholder may "tag along" and sell their shares to the same buyer on the same terms and at the same price per share. Like a drag-along, a tag-along is a contractual right — a minority shareholder has it only if the agreement (or the MOI) says so.
The tag-along right addresses a real and serious risk for minority shareholders. Without it, a majority shareholder could sell a controlling stake to an unknown third party, leaving the minority trapped in the company with a new majority shareholder they did not choose and cannot control. The minority may dislike the new majority's business philosophy, strategic direction, or management approach — but without a tag-along, they have no exit.
How Tag-Along Rights Work
Sale Notice
The majority shareholder gives written notice to the minority that they intend to sell their shares — disclosing the buyer's identity, the price per share, and the proposed terms.
Tag-Along Election Period
The minority has a defined period (typically 10 to 15 business days) to elect to participate in the sale by giving a written tag-along notice to the majority and the proposed buyer.
Pro-Rata Participation
If the buyer is only willing to acquire a portion of the company's shares, the minority can tag along pro-rata to their existing shareholding. The buyer is not a party to the shareholders agreement and is not automatically bound by it, so the clause works through the seller: the majority must procure that the buyer makes the same offer to the minority, or not proceed with the sale.
Same Terms
The minority sells on the same terms — same price per share and same payment structure. The agreement should say how this works where there are different share classes or non-cash consideration, and how far a minority seller must give warranties and representations.
Permitted Transfers
Not every transfer of shares is subject to the full pre-emptive right process. Shareholders agreements typically carve out a category of "permitted transfers" that can occur without triggering the other shareholders' rights to purchase. These carve-outs exist to allow shareholders to undertake legitimate estate planning and corporate restructuring without being hamstrung by the agreement's transfer restrictions.
Transfer to a Wholly-Owned Subsidiary
A shareholder may transfer their shares to a company that is wholly owned by that shareholder. This allows for corporate restructuring without changing the ultimate beneficial owner. The agreement typically requires that if the subsidiary ceases to be wholly owned, the shares must immediately be transferred back.
Transfer to a Family Trust
A shareholder may transfer shares to a family trust for estate planning purposes. The agreement should set clear eligibility criteria — for example, who the beneficiaries may be and what happens if the trust later changes — so that the carve-out cannot be used to pass the shares to outsiders. Check the trust deed and the trustees' authority to hold the shares and to sign the deed of adherence. Avoid a test that requires the founder to keep personal control of the trust: trustees must take decisions properly and jointly under the Trust Property Control Act 57 of 1988, and too much personal control can undermine the estate planning the trust was set up to achieve.
Intra-Group Transfers
Where a shareholder is itself a company, transfers between related entities within the same group (as defined in the Companies Act — entities under common control) are typically permitted without triggering pre-emptive rights.
Court-Ordered Transfers
Transfers required by operation of law or pursuant to a court order cannot practically be blocked by contractual transfer restrictions. The agreement should acknowledge this and provide, as far as the law allows, that the transferee signs a deed of adherence before being registered as a shareholder.
Deed of Adherence
A deed of adherence is a short agreement executed by an incoming shareholder — whether they acquire shares by transfer, subscription, or as a permitted transferee — by which they confirm that they are bound by the terms of the existing shareholders agreement as if they had been an original party to it.
The deed of adherence is critical for two reasons. First, the shareholders agreement is a contract — it binds only the parties to it, and a new shareholder does not become a party just by acquiring shares. Without a deed of adherence, a new shareholder can argue they are not bound by the agreement's restrictions. Second, it ensures continuity: as the shareholder base changes over time, the web of obligations created by the shareholders agreement extends to cover every new entrant.
What a Deed of Adherence Should Cover
- Confirmation that the incoming shareholder has read and understood the shareholders agreement
- Agreement to be bound by all obligations applicable to shareholders under the agreement
- Entitlement to all rights afforded to shareholders under the agreement
- Acknowledgement of any specific obligations applicable to the transferred shares (e.g., BEE lock-in, funded equity obligations)
- Undertaking not to transfer shares except in accordance with the agreement
Practical Warning
The shareholders agreement should make a signed deed of adherence a condition of every transfer, and the MOI should contain a matching restriction so that the company itself is entitled to refuse to register a transferee who has not signed. A clause in the shareholders agreement alone does not automatically make a non-compliant transfer void, or authorise the company to refuse registration — the result depends on the MOI, the agreement and the applicable law. In practice, build the deed into the completion checklist so that the register is only updated once the deed is signed.
Share Transfer and BEE Compliance
For companies that rely on their B-BBEE ownership scorecard — particularly those that tender for government contracts, hold licences issued under sector-specific legislation, or supply to multinationals with procurement requirements — the shareholders agreement must carefully manage the transfer of BEE-qualifying shares.
B-BBEE Lock-In Provisions
The B-BBEE Codes of Good Practice look for genuine ownership: black shareholders must really hold the voting rights and economic interest attributed to them, not merely appear on the register. But the Generic Codes do not lay down a universal rule that BEE shareholders must hold their shares for three to five years before the ownership can count. Ownership is measured under the code that applies to the company — the Generic Codes or a sector code — and some industries have their own instruments (mining ownership, for example, is dealt with under the Mining Charter, which is a separate regime and not simply another B-BBEE sector code). The Codes also have their own rules on when ownership can still be recognised after a black shareholder has exited, and those rules carry conditions. A lock-in is therefore a commercial protection the parties negotiate. It does not by itself prove that the ownership is genuine, and ordinary investor protections do not automatically amount to fronting. Test the actual rights against the instrument that applies to your company.
Possible Consequences of a BEE Shareholder Exiting
- A loss of ownership points on the B-BBEE scorecard, potentially triggering a drop in the company's B-BBEE level — recognition is not always lost automatically, because the Codes allow continued recognition after an exit where specific conditions are met
- Jeopardy of contracts, licences, or tenders that were awarded based on the company's B-BBEE status
- Potential breach of any regulatory conditions attached to licences that require a minimum level of black ownership
- Reputational damage and loss of procurement preference with clients who require specific B-BBEE levels
What the SHA Must Address
Mandatory Replacement BEE Shareholder
The agreement should require that if the BEE shareholder exits (whether voluntarily or involuntarily), the shares must be sold to a replacement black-owned entity that maintains the same or better BEE qualification. The remaining shareholders typically have a right of first offer, failing which the exiting BEE shareholder must source a qualifying replacement.
Clawback of Funded Equity
Where the BEE shareholder acquired their shares through vendor financing or a special-purpose financing structure, the SHA must specify what happens to outstanding amounts owed if the BEE shareholder exits early. The answer depends on how the deal is structured: shares bought outright with a loan, an option, and shares that vest over time are different arrangements with different consequences. The SHA and the funding documents should say how unpaid funding is settled on an early exit, and the effect on the ownership score should be tested against the applicable code.
Board Notification Obligations
The SHA should require the BEE shareholder to immediately notify the board if their B-BBEE qualification status changes — for example, if a change in their own shareholding structure means they no longer qualify as a black-owned entity under the relevant code.
Involuntary Transfers
Not all share transfers are voluntary. A shareholder may die, become insolvent, or have their shares attached pursuant to a divorce order or judgment. Each of these events can cause shares to pass into the hands of persons who were never intended to be shareholders. A well-drafted SHA should address each scenario explicitly.
One caution applies to all three. The SHA can set a tailored procedure for death, insolvency and divorce, but that procedure always operates subject to succession, insolvency and matrimonial-property law. An agreement between shareholders cannot take away the powers of a court, an executor or an insolvency trustee, and it cannot override creditors' rights. For each event, the clause should spell out who may or must buy, at what price, by when, and how the purchase will be funded.
Death of a Shareholder
Upon death, shares vest in the deceased's estate and are administered by the executor appointed under the Administration of Estates Act 66 of 1965. The SHA should provide that:
- The executor must offer the deceased's shares to the surviving shareholders before transferring them to any heir or legatee
- The survivors either must buy the shares or merely have an option to buy them — death does not automatically oblige co-shareholders to purchase, so the agreement must say which applies and how the price will be funded
- The exercise period for surviving shareholders is extended to account for the time required to wind up an estate
- The price is determined by a valuation mechanism — either an independent valuer or a formula — to avoid disputes between the estate and the surviving shareholders
- If surviving shareholders do not exercise their right, the heir or legatee may become a shareholder provided they execute a deed of adherence
Insolvency of a Shareholder
Upon sequestration, a shareholder's estate — including their shares — vests in the Master of the High Court and is administered by a trustee under the Insolvency Act 24 of 1936. The SHA will usually provide that:
- Sequestration constitutes a deemed offer to sell — triggering the pre-emptive right process immediately
- The shares are offered to the remaining shareholders before they are sold to a third party
- The price is determined by independent valuation, since the insolvent shareholder is no longer in a position to negotiate
These clauses are widely used, but no one can promise that they will always bind the insolvent estate. The trustee has statutory powers, creditors have rights, and insolvency law allows certain transactions to be set aside. A forced sale at a discount is the most exposed to challenge; a fair-value price is safer. Insolvency scenarios need advice on the specific facts.
Divorce and Attachment of Shares
Divorce does not automatically transfer shares to a spouse. What happens depends on the couple's matrimonial property regime and on the actual court order or settlement. Where shares form part of the joint estate in a marriage in community of property, a divorce order may award the shares (or a portion of their value) to the non-shareholder spouse. Similarly, a judgment creditor may attach shares via a writ of execution. The SHA should provide that:
- Any court order or attachment triggers the pre-emptive right — the remaining shareholders have priority to purchase before any third party acquires the shares
- The SHA's restrictions are recorded against the shares in the share register, putting third parties on notice
- The shareholder indemnifies the company and remaining shareholders for any costs arising from enforcing the SHA against a divorce-related claim
Keep in mind that keeping an ex-spouse or heir off the share register does not necessarily remove their claim to the value of the shares. The SHA controls who becomes a shareholder; it does not decide what a spouse or heir is entitled to.
Share Transfer Process
Once a share transfer has been properly concluded under the SHA — whether through exercise of a pre-emptive right, ROFR, drag-along, tag-along, or permitted transfer — the parties must complete the formal legal transfer process. This involves the following practical steps:
Notice Under the SHA
Issue the required notice (offer notice, drag notice, tag notice, or permitted transfer notice) in accordance with the SHA's notice provisions. Ensure the notice contains all required information and is delivered by the stipulated method (typically registered post and email).
Exercise Period and Agreement
Allow the exercise period to run. If the right is exercised, the parties conclude a share sale agreement setting out the price, payment terms, warranties, and conditions precedent (such as regulatory approvals where required).
Deed of Adherence
The incoming shareholder (if a new party to the SHA) executes the deed of adherence before completion.
Securities Transfer Form
The transferor and transferee sign a securities transfer form (STF) and deliver it to the company. Under section 51 of the Companies Act, the company may only register a transfer on a proper instrument of transfer, unless the shares pass by operation of law (for example, to an executor). Keep three things apart: the sale agreement, the transfer of the rights in the shares, and registration of the buyer as holder in the company's register. The STF is not lodged at CIPC but is retained in the company's records.
Update the Share Register
The company secretary or director updates the company's share register to record the new shareholder and the number of shares transferred. The share register must reflect the current shareholding at all times as required by section 50 of the Companies Act.
Account for STT and Update Beneficial Ownership
Securities Transfer Tax (STT) of 0.25% on the greater of the consideration or market value is normally payable, unless an exemption applies. For unlisted shares the company is liable for the STT and may recover it from the transferee. There are two separate STT deadlines: the transferee must notify the company of the transfer within 30 days, and the company must pay SARS within two months after the end of the month in which the transfer took place. Many sale agreements require the buyer to fund the STT at completion — that is a term of the deal, not the SARS deadline. Beneficial ownership runs on a different, shorter clock: where the transfer changes the company's beneficial ownership (for companies required to keep a beneficial ownership register under the General Laws Amendment Act 22 of 2022), update the company's record and make the CIPC beneficial-ownership filing within 10 business days of the change. Complete any director or MOI filings the transaction requires. A routine share transfer does not otherwise need to be notified to CIPC, and the signed SHA and deed of adherence stay with the company's records — they are not lodged with CIPC.
Comparison: The Four Main Transfer Mechanisms
A well-structured shareholders agreement typically combines multiple transfer restriction mechanisms. Understanding how they interact and what each one is designed to achieve helps in negotiating the right combination for your company's particular circumstances.
| Mechanism | Trigger | Direction | Primary Purpose |
|---|---|---|---|
| Pre-emptive right (right of first offer) | Shareholder wants to sell | Existing shareholders offered first | Control who enters — prevents third-party entry without opportunity for existing shareholders to absorb |
| Right of first refusal (ROFR) | Third-party offer received | Existing shareholders can match the offer | Market-priced buyout — price established by third-party offer rather than seller alone |
| Drag-along right | Majority sells to third party | Forces minority to sell on same terms | Enable clean 100% exit — prevents minority from blocking a beneficial whole-of-company sale |
| Tag-along right | Majority sells to third party | Allows minority to join the sale | Protect minority — prevents minority being left with an unknown new majority shareholder |
Drafting Consideration: Order of Priority
When multiple mechanisms apply to the same triggering event — for example, a majority sale that triggers both a pre-emptive right and a tag-along right — the agreement must specify which takes priority and in what sequence. Typically the pre-emptive right operates first: if existing shareholders fully exercise the right, there is no third-party sale and therefore no tag-along trigger. Only if the pre-emptive right is not exercised does the tag-along right become relevant.
