A shareholders’ agreement is often overlooked at the start of a new business venture. When shareholders are aligned and optimism is high, it can feel unnecessary. However, experience shows that this document is one of the most important safeguards a company can put in place.

A well-drafted shareholders’ agreement provides clarity, manages expectations and helps prevent disputes by setting out how the company will be run and what happens when circumstances change. At Eaton Smith Solicitors, we regularly advise clients on putting these agreements in place at the right time, tailored to the needs of their business.

Below, we outline the key provisions typically included in a UK shareholders’ agreement and explain why they matter.

The Purpose of a Shareholders’ Agreement

A shareholders’ agreement is a private contract between some or all of a company’s shareholders. It sits alongside the company’s Articles of Association, covering matters that are often too detailed, commercially sensitive or flexible to include in the Articles.

Its role is to establish clear ground rules for decision-making, ownership and exits, reducing uncertainty and helping shareholders avoid costly disputes as the business grows or evolves.

Management and Decision-Making

Most shareholders’ agreements address how the company is managed and how decisions are taken.

They typically distinguish between:

• Day-to-day matters, which can be handled by the board, and
• Reserved matters, which require shareholder approval.

Reserved matters often include issuing new shares, borrowing above agreed limits, selling significant assets or changing the nature of the business. These decisions frequently require a higher voting threshold, such as a supermajority, to ensure broader shareholder consent.

Agreements also commonly cover:

• The appointment and removal of directors
• Shareholder rights to nominate directors
• Board composition and voting procedures
• Director remuneration and service contracts

Together, these provisions help ensure transparency, accountability and consistency at board level.

Share Ownership and Transfers

Rules governing share ownership and transfers are central to any shareholders’ agreement.

Common provisions include:

• Transfer restrictions, preventing shareholders from selling to third parties without consent
• Pre-emption rights, giving existing shareholders first refusal on share sales or new share issues
• Drag-along rights, enabling majority shareholders to require minority shareholders to sell on the same terms during a company sale
• Tag-along rights, allowing minority shareholders to exit on equivalent terms when the majority sells

Leaver provisions are also critical. These address what happens when a shareholder leaves due to resignation, retirement, ill health, death or insolvency. Agreements often distinguish between good leavers and bad leavers, with different valuation outcomes depending on the circumstances. Having a clear valuation mechanism in place can significantly reduce the risk of disputes at what is often a sensitive time.

Funding and Financial Arrangements

Financial provisions ensure all shareholders understand how the company will be funded and how returns will be shared.

These clauses may cover:

• Obligations to provide further funding
• Consequences of failing to contribute
• Dividend policy, including whether profits are to be reinvested or distributed

In companies with external investment, liquidation preferences may also be included. These determine the order and priority of payments if the company is sold or wound up.

Minority Shareholder Protection

A shareholders’ agreement can provide important protections for minority shareholders, helping to prevent unfair prejudice.

Typical protections include:

• Enhanced voting rights
• Veto rights over certain key decisions
• Additional consent requirements for fundamental changes

Information rights are also important, ensuring shareholders receive regular financial and management information even if they are not involved in the day-to-day running of the company.

Restrictive Covenants

Restrictive covenants are designed to protect the company if a shareholder becomes involved in a competing business.

These may include non-compete and non-solicitation obligations during ownership and for a defined period after a shareholder exits. To be enforceable under UK law, such restrictions must be carefully drafted so they are no wider than reasonably necessary to protect the business.

Deadlock and Dispute Resolution

Even in well-run companies, disagreements can arise. Deadlock provisions are particularly important where shareholdings are evenly split.

These clauses may include:

• Escalation procedures
• Mediation or other forms of alternative dispute resolution
• Structured buy-out mechanisms

Requiring mediation or arbitration before court proceedings can help minimise costs, preserve relationships and resolve disputes more efficiently.

Why Taking Advice Early Matters

A carefully drafted shareholders’ agreement can:

• Prevent disputes before they arise
• Protect shareholder investments
• Provide clarity around exits and unexpected events

Crucially, it allows shareholders to agree the rules of engagement while relationships are positive, rather than trying to resolve issues in the midst of a dispute.

As every business is different, shareholders’ agreements should always be bespoke. At Eaton Smith Solicitors, we work closely with clients to ensure their agreements accurately reflect their commercial objectives and align with their company’s Articles of Association.
