Share Transfer Restrictions: Can Your Shareholders Sell to Anyone They Like?

Key takeaways

• The articles set the rules: Shares are transferable in the manner the articles provide. Under the Model Articles, the only control is the directors’ discretion to refuse to register a transfer. 

• Refusals must be explained: A company must register a transfer or give notice of refusal with reasons as soon as practicable and in any event within two months. 

• Pre-emption on transfer is contractual: There is no statutory right of first refusal when shares are sold. It exists only if the articles or a shareholders’ agreement create it, and the courts apply it as written. 

• Balance is everything: Restrictions that are too loose let outsiders in. Restrictions that are too tight can trap shareholders and invite disputes. 

Who your co-owners are matters as much as what they own. A founder who sells to a competitor, an investor who transfers to an unknown fund, or a shareholder who dies leaving shares to relatives who have never seen the business can change the character of a private company overnight. Share transfer restrictions decide who can become a shareholder and on what terms, and they are one of the first things a buyer or investor will check. 

This article explains the legal starting point, the restrictions most private companies use, how the courts interpret them and the points that are often missed. 

What is the legal starting point?

Shares are transferable in the manner provided by the company’s articles, subject to the Companies Act 2006 and other legislation (Part 17 of the Companies Act 2006). A company may not register a transfer unless a proper instrument of transfer has been delivered to it, or the transfer is exempt or made through an electronic system (section 770). 

If the company uses the Model Articles, shares may be transferred by an instrument in any usual form, and the directors may refuse to register any transfer (article 26). That discretion is wide, but it is not unlimited. Directors must exercise it in good faith in what they consider, not what a court may consider, to be in the interests of the company, and not for a collateral purpose (Re Smith & Fawcett Ltd [1942] Ch 304, at 306). 

A refusal also carries procedural obligations. The company must either register the transfer or give the transferee notice of refusal together with its reasons, as soon as practicable and in any event within two months of the transfer being lodged. It must also provide any further information about the reasons that the transferee reasonably requests, although not copies of board minutes. Following the Economic Crime and Corporate Transparency Act 2023, the company may not register a transfer unless it has the information about the transferee that it must enter in its register of members (section 771). 

Most companies with more than one shareholder will want more than a board discretion. The usual tools are set out below. 

What restrictions do private companies commonly use?

• Pre-emption on transfer. A shareholder who wants to sell must first offer the shares to the other shareholders, usually at the price offered by the proposed buyer or at fair value set by an independent valuer. Only if they decline can the shares be sold to an outsider, typically within a fixed period and at no lower price. 

• Right of first offer. A lighter version, under which the seller must invite offers from the existing shareholders before approaching third parties. 

• Lock-ups. A ban on transfers for a fixed period, often used for founders after an investment round. 

• Prohibited transferees. A ban on transfers to competitors, or to anyone the board or an investor majority has not approved. 

• Permitted transfers. Carve-outs allowing transfers to family members, family trusts or companies controlled by the shareholder, without triggering pre-emption. These should include a “claw-back” requiring the shares to be transferred back if, for example, the family company ceases to be controlled by the original shareholder. 

• Compulsory transfers. Provisions requiring a shareholder to offer their shares for sale on events such as ceasing to be employed, bankruptcy, death or a change of control of a corporate shareholder. See our article on good and bad leaver provisions. 

These are distinct from statutory pre-emption rights, which apply only when a company allots new equity securities for cash (section 561). There are no statutory pre-emption rights on a transfer of existing shares. 

How do the courts interpret pre-emption provisions?

Pre-emption provisions are construed according to what they actually say. In Re Coroin Ltd [2013] EWCA Civ 781, a shareholder in the company that owned Claridge’s, The Connaught and The Berkeley argued that arrangements under which another shareholder’s stake came under the control of a rival group should have triggered his pre-emption rights. The arrangements gave the rival group control of the shares, but stopped short of transferring a proprietary interest in them. The Court of Appeal held that the pre-emption provisions had not been triggered. The parties had been specific about the transactions that were prohibited, and a mere transfer of control was not one of them (at [36] and [40]). As the court put it, it can only enforce the agreement that the parties have actually made. 

The lesson for drafting is clear. If the shareholders want pre-emption rights to catch a change of control of a corporate shareholder, a grant of security, a declaration of trust or an agreement over voting rights, the articles must say so expressly, usually through “deemed transfer notice” provisions. The court in Coroin also confirmed that directors should not register a transfer made in breach of pre-emption provisions, and that if they do, the company or another member can apply to rectify the register (at [93] to [94]). 

Can a company ban transfers altogether?

In principle, the articles can impose very tight restrictions. An absolute prohibition, however, can leave a shareholder with no way out except a sale back to the company, which may not be able or willing to buy. That raises practical problems on death or insolvency, and it can make an unfair prejudice petition more likely (section 994). The House of Lords in O’Neill v Phillips [1999] UKHL 24 identified restrictions on transfer, “so that a member cannot take out his stake and go elsewhere”, as one of the features of a quasi-partnership in which the court may give weight to informal understandings between shareholders. A balanced combination of pre-emption rights, permitted transfers and a fair valuation mechanism is usually more effective than a ban. 

What else should the articles and shareholders’ agreement cover

Transfer restrictions only work if the documents fit together. The restrictions must appear in the articles, because the articles bind every current and future shareholder (section 33), whereas a shareholders’ agreement binds only those who sign it. The shareholders’ agreement can repeat the restrictions, require new shareholders to sign a deed of adherence and say which document prevails. The provisions should also deal with transmission of shares on death or bankruptcy (article 27 of the Model Articles), the valuation process, how notices are served and what happens if a shareholder ignores them. Pre-emption should be disapplied for transfers under drag-along and tag-along rights, so that a sale of the whole company cannot be blocked. See our article on drag-along and tag-along rights. 

Share transfer restrictions: a practical checklist

When putting in place or reviewing share transfer restrictions, shareholders are likely to need to consider: 

• Board discretion. Whether the directors should have a general power to refuse registration, and on what grounds. 

• Pre-emption. Who has priority, how the price is set and the timetable for acceptance. 

• Triggers. Whether changes of control, security, trusts and voting arrangements are caught. 

• Permitted transfers. Family, trusts and affiliates, with claw-back provisions. 

• Prohibitions. Lock-ups and transfers to competitors. 

• Compulsory transfers. Leavers, death, bankruptcy and change of control. 

• Exit. Disapplying pre-emption on drag and tag sales. 

• Process. The two-month deadline for registering or refusing a transfer, and keeping the register of members up to date. 

At Maybrook Law, we draft share transfer provisions for private companies, investors and joint venture partners, and we act in disputes when transfers are challenged. That experience of both sides shapes how we draft. If your company is bringing in new shareholders, or a proposed transfer is causing concern, we would be pleased to advise on your position.
