Shareholders' Agreements - Why Every Company Needs One — and What It Should Contain 

A shareholders’ agreement is one of the most important legal documents a company can have. Yet it is one of the most frequently overlooked — particularly by start-ups and early-stage businesses, where founders often feel that a formal legal agreement is unnecessary between people who know and trust each other. 

That view, however understandable, is mistaken when considering the implications of a comprehensive agreement. A shareholders’ agreement does not reflect a lack of trust between co-founders or co-investors. On the contrary, it is an act of professionalism and foresight: a document that protects all parties, aligns their expectations, and provides a clear and agreed framework for the most important decisions a company will face — including what happens if things go wrong. 

Without a shareholders’ agreement, the rights and obligations of shareholders are governed solely by the company’s Articles of Association and by the Companies Act 2006. While the Act provides a basic legal framework, its default rules were not designed with the specific circumstances of your company or your shareholder relationships in mind. They are generic, inflexible, and frequently inadequate for the needs of a closely-held business. 

This guide explains what a shareholders’ agreement is, why it matters, what it should contain, and how Ronald Fletcher Baker LLP can help you put the right protections in place. 

1.  What Is a Shareholders’ Agreement? 

A shareholders’ agreement is a private contract between some or all of the shareholders of a company, usually also signed by the company itself. Unlike the Articles of Association — which are a public document filed at Companies House and which bind all shareholders as a matter of company law — a shareholders’ agreement is confidential. Its terms are not available to the public, to competitors, or to third parties. 

The agreement supplements and (within limits) overrides the Articles of Association by setting out the specific rights, obligations and protections that the shareholders have agreed amongst themselves. It deals with matters that either are not covered by the Articles at all, or where the statutory default position is unsuitable for the particular company and its shareholders’ rights and regulations. 

A well-drafted shareholders’ agreement is tailored to the circumstances of the individual company. It reflects the nature of the business, the number and type of shareholders, the structure of ownership, any investment arrangements, and the commercial objectives of the parties. No two shareholders’ agreements are identical — and any agreement that appears to be a ‘standard template’ should be treated with caution. 

A shareholders’ agreement vs the Articles of Association 

1. The Articles of Association are a public document, filed at Companies House and accessible to anyone 

2. A shareholders’ agreement is private and confidential — its terms are known only to the parties 

3. Articles bind all shareholders by virtue of company law; a shareholders’ agreement binds only those who sign it 

4. Articles can be amended by a 75% shareholder vote (a special resolution); a shareholders’ agreement typically requires unanimous consent to vary key clauses. 

5. Both documents should be drafted in conjunction with one another to avoid inconsistency 

2.  Why Does Your Company Need One? 

The short answer is: because disputes happen — even between people who start out with the best of intentions — and because the issues a shareholders’ agreement addresses will arise for every company at some point, whether that is a shareholder wanting to leave, a founder losing their commitment to the business, an investor seeking an exit, or a deadlock between equal shareholders over a critical decision. 

Consider the following scenarios, all of which arise regularly in practice: 

Common situations where the absence of a shareholders’ agreement causes serious problems: 

• Two equal (50/50) shareholders fundamentally disagree on a major business decision and neither can outvote the other — the company is deadlocked with no mechanism to resolve it 
• A founder leaves the business — or is asked to leave — but retains all of their shares, continuing to benefit from the company’s success while contributing nothing to it 
• A shareholder unexpectedly dies, and their shares pass to a family member with no connection to or interest in the business 
• A shareholder proposes to sell their shares to a third party — potentially a competitor — and the remaining shareholders have no right to prevent it 
• The company needs further investment, but shareholders cannot agree on whether to dilute existing holdings or on what terms to bring in a new investor 
• A shareholder who leaves to work for a competitor takes key contacts and confidential information with them, with no contractual restrictions in place 
• Minority shareholders are oppressed by majority decisions — for example, a refusal to pay dividends while majority shareholders extract value through salaries 

In each of these situations, a carefully drafted shareholders’ agreement — entered into at the outset — would either have prevented the dispute from arising, or provided a clear contractual mechanism to resolve it. 

The cost of drafting a shareholders’ agreement at the start is invariably a small fraction of the cost of resolving a shareholder dispute after the event — which can run to tens or hundreds of thousands of pounds in legal fees, management time and lost business value. 

3.  What Does a Good Shareholders’ Agreement Contain? 

The contents of a shareholders’ agreement will vary depending on the company and its circumstances. However, a well-drafted agreement for a private limited company will typically address the following key areas: 

1: Share Capital and Ownership

The agreement should record the current share capital of the company, the classes of shares in issue, and the shareholding of each party. It may also regulate how and when further shares may be issued, and on what terms — including pre-emption rights (see below).

2: Management and Decision-Making

The agreement sets out how the company is to be managed, including the composition of the board of directors, how directors are appointed and removed, voting rights at board level, and which decisions require shareholder approval. This is one of the most important areas of any shareholders’ agreement, as it governs how power is exercised within the company.

3: Reserved Matters

Reserved matters are decisions that are too significant to be taken by the directors or by ordinary majority vote — and which therefore require the consent of a defined majority of shareholders (or, in some cases, unanimity). A well-drafted list of reserved matters is essential to protect minority shareholders from having major decisions imposed on them. Typical reserved matters include: issuing new shares, taking on material debt, making acquisitions or disposals above a threshold value, amending the Articles, changing the nature of the business, and approving the annual budget.

4: Dividend Policy

The agreement may specify a dividend policy — for example, that a defined percentage of distributable profits will be paid as dividends in each financial year, subject to the requirements of the business. Without a dividend policy, the majority can decide to retain all profits within the company, potentially leaving minority shareholders unable to realise any return on their investment.

5: Pre-emption Rights on Share Transfers

Pre-emption rights require a shareholder who wishes to sell their shares to first offer them to the existing shareholders (pro rata to their existing holdings) before selling to a third party. This protects existing shareholders from finding that their fellow shareholder has sold to an outsider — potentially a competitor or an unwanted investor — without their knowledge or consent. Pre-emption rights are a standard and fundamental provision in any shareholders’ agreement.

6: Permitted Transfers

The agreement should specify the circumstances in which shares may be transferred without triggering pre-emption rights — for example, to family members, to trustees of a shareholder’s family trust, or to a holding company. These are known as ‘permitted transfers’. The scope of permitted transfers should be carefully considered to ensure that it does not allow shares to pass into the hands of unwanted third parties.

7: Drag-Along Rights

Drag-along rights allow a majority of shareholders (typically holders of a specified percentage, such as 75%) to require the remaining shareholders to sell their shares on the same terms when the majority wishes to sell the entire company. Without drag-along rights, a small minority can hold up a sale of the company by declining to participate — which can destroy the value of the transaction for the majority. Drag-along rights ensure that the majority are able to deliver 100% of the company’s shares to a buyer.

8: Tag-Along Rights

Tag-along rights are the counterpart of drag-along rights: they protect minority shareholders by requiring that, if a majority shareholder (or group of shareholders) sells their shares to a third party, the minority must be given the right to participate in the sale on the same terms and at the same price. Without tag-along rights, a majority shareholder could sell to a buyer who then leaves the minority locked in with a new and potentially unwelcome co-shareholder.

9: Good Leaver / Bad Leaver Provisions

These provisions deal with what happens to a shareholder’s shares when they leave the company — whether by resignation, dismissal, retirement, death or incapacity. A ‘good leaver’ (typically someone who leaves for reasons beyond their control, such as death, ill health, or redundancy) will usually be entitled to receive fair value for their shares. A ‘bad leaver’ (typically someone who resigns without good reason, is dismissed for cause, or breaches the agreement) may be required to sell their shares at a discount — sometimes at cost price or even nominal value. Good leaver / bad leaver provisions are particularly important in companies where shareholders are also employees or directors, and are central to ensuring that departing founders and key individuals cannot continue to benefit from equity they did not earn.

10: Vesting

Vesting provisions (common in start-up and investor-backed companies) mean that a shareholder’s economic entitlement to their shares is earned over time, typically over a three- or four-year period. If a shareholder leaves before their shares have fully vested, they may be required to return some or all of their unvested shares to the company. Vesting aligns the interests of shareholders with the long-term success of the business and prevents early departures from disproportionately rewarding short-term involvement.

11: Deadlock Provisions

Deadlock occurs when shareholders are equally split on a decision and neither side can prevail. This is particularly acute in 50/50 companies but can arise in any company with an even voting structure. A shareholders’ agreement should include deadlock provisions that specify what happens in this situation — for example, escalation to senior management, mediation, or ultimately a ‘Russian roulette’ or ‘shoot-out’ mechanism (where one shareholder names a price at which they will either buy the other’s shares or sell their own).

12: Confidentiality

The agreement should include robust confidentiality obligations, preventing shareholders from disclosing the company’s confidential information — including its business plans, financial information, customer lists, and trade secrets — to third parties. This is important both during the shareholder’s involvement with the company and after their departure.

13: Non-Compete and Non-Solicitation Covenants

These covenants restrict what a departing shareholder can do after leaving the company. A non-compete provision prevents them from establishing or working for a competing business for a specified period and within a specified geographical area. A non-solicitation provision prevents them from approaching the company’s customers, suppliers or employees. To be enforceable under English law, these covenants must be reasonable in scope, duration and geography — which underscores the importance of taking legal advice when drafting them.

14: Funding and Finance

The agreement should address how the company will be funded going forward — including whether shareholders are obliged to contribute further capital if required, on what terms new investment may be brought in, and how decisions about taking on debt are made. This is particularly important in companies where there is unequal financial commitment between shareholders or where external investment is anticipated.

15: Exit Provisions

Most investors will want clarity on how and when they can realise a return on their investment. The agreement may include provisions governing an initial public offering (IPO), a trade sale, or a management buy-out as exit routes, and may specify that the shareholders are obliged to use reasonable endeavours to achieve a sale or listing within a defined timeframe. Exit provisions are a standard feature of venture capital and private equity investment agreements.

16: Dispute Resolution

The agreement should specify how disputes between shareholders are to be resolved — whether through negotiation, mediation, or arbitration — before resorting to litigation. Including a structured dispute resolution mechanism can save significant time and cost if a dispute arises, and can help to preserve the relationship between shareholders even when there is disagreement.

4.  Shareholders’ Agreements in Different Contexts 

The provisions that matter most in a shareholders’ agreement will vary depending on the type and stage of the company. Some common contexts include: 

Start-Up and Founder Companies 

For a company with two or three co-founders, the most critical provisions are typically: decision-making and reserved matters (to ensure equal founders have a mechanism for resolving deadlock), good leaver / bad leaver provisions (to deal with the departure of a co-founder who loses interest or falls out with the others), vesting (to ensure equity is earned over time), non-compete covenants, and pre-emption rights. A founders’ shareholders’ agreement need not be complex, but it must address these fundamentals. 

Investment Rounds (Seed, Series A and Beyond) 

When a company raises external investment, investors will almost invariably require a shareholders’ agreement — or an amendment to an existing one — as a condition of their investment. Investor-focused agreements typically include: anti-dilution protections, information rights (the investor’s right to receive financial information and attend board meetings), preferred dividend and liquidation rights, consent rights over key decisions, drag-along and tag-along rights, and specific exit provisions. Founders should take independent legal advice before signing any investor-driven shareholders’ agreement, as the terms can significantly affect their economic position and control over the business. 

Joint Ventures 

Where two or more businesses come together to operate a joint venture through a jointly-owned company, a shareholders’ agreement (sometimes called a joint venture agreement) is essential. The key issues typically include: governance and management control, funding obligations, the handling of deadlock (which is particularly significant given the often equal ownership structure), restrictions on competing activity, and the circumstances in which one party may exit the joint venture. 

Family Companies and Management Buy-Outs 

In family-owned businesses and management buy-out vehicles, the shareholders’ agreement may need to address succession planning, restrictions on transfer to non-family members, the role and remuneration of family members who work in the business, and the rights of family members who hold shares but are not involved in operations. These are sensitive areas that require careful and bespoke drafting. 

5.  When Should You Put a Shareholders’ Agreement in Place? 

The right time to put a shareholders’ agreement in place is at the outset — before disputes arise, before investment is received, and before relationships become strained. Like insurance, a shareholders’ agreement is most valuable when it is taken out before it is needed. 

In practice, many companies do not have a shareholders’ agreement at incorporation and come to us to draft one later. This is perfectly possible, but there are two important considerations: 

• All existing shareholders must agree to the terms of the agreement and sign it. The more shareholders there are, and the more time has passed, the more complex (and sometimes contentious) this process can become. 
• Putting an agreement in place retrospectively — particularly where existing relationships are already strained — can be more difficult and expensive than doing so at the outset. 

Our strong recommendation is to put a shareholders’ agreement in place at or shortly after incorporation, before the company has significant value and before any of the issues the agreement is designed to address have had a chance to arise. 

Key triggers for reviewing or putting in place a shareholders’ agreement: 

• Incorporating a new company with two or more shareholders 
• Bringing in a new co-founder, business partner or key employee with equity 
• Raising investment from an angel investor, seed fund or venture capital firm 
• Entering into a joint venture with another business 
• Any shareholder wishing to transfer or gift shares 
• A change in the shareholders’ relative holdings or the classes of shares in issue 
• A significant change in the nature, scale or direction of the business 

6.  Common Mistakes to Avoid 

In our experience advising companies and shareholders, the following are among the most common and costly mistakes: 

• Using a free or generic online template. A shareholders’ agreement is not a document that benefits from a ‘one size fits all’ approach. Templates may omit provisions that are critical for your company, or include provisions that are inappropriate or unenforceable in your circumstances. 
• Failing to align the shareholders’ agreement with the Articles of Association. Inconsistencies between the two documents can create significant uncertainty and give rise to disputes about which document prevails. Both should be drafted or reviewed together. 
• Overlooking tax implications. The transfer of shares and the terms of leaver provisions can have significant tax consequences — including income tax, capital gains tax and potentially inheritance tax. Tax advice should be taken alongside legal advice when structuring any shareholders’ agreement. 
• Drafting non-compete covenants that are too wide. Overly broad non-compete provisions are unenforceable under English law as being in restraint of trade. They must be no wider than is reasonably necessary to protect the company’s legitimate business interests. 
• Neglecting to update the agreement as the company evolves. A shareholders’ agreement that was appropriate for a two-person start-up may be wholly inadequate once the company has raised investment, expanded its board, or taken on additional shareholders. The agreement should be reviewed and updated at every significant milestone. 
• Signing an investor’s standard form agreement without negotiation. Investors’ standard form documents are drafted to protect the investor’s interests — not the founders’. Key terms such as anti-dilution ratchets, liquidation preferences and consent rights should always be negotiated with the benefit of independent legal advice.
