Shareholder agreements are private agreements between shareholders on how they will regulate the relationship between themselves.

A shareholders’ agreement often addresses the following:

• How liabilities will be apportioned
• Restrictions on, or mechanisms for, creating, issuing or transferring shareholdings.
• Provisions for the exit of a shareholder.
• Options to acquire other shareholder’s shares.

Shareholders Agreements: What You Need to Know

For businesses with multiple owners, a Shareholders Agreement is an important document. It sets out shareholders’ rights, responsibilities and expectations, helping prevent disputes and protecting the interests of both the shareholders and the business.

What is a Shareholders Agreement?

A Shareholders Agreement is a legally binding private contract between a company’s shareholders. It sets out how the company will be run, how key decisions will be made and how shareholders will work together.

Unlike the Articles of Association, which are publicly available at Companies House, a Shareholders Agreement is private and is not legally required. However, it provides greater flexibility and protection.

It can cover matters including voting rights, management responsibilities, share transfers, dividends and how disputes will be resolved.

What types of Shareholders Agreement are there?

The agreement should reflect the structure and needs of the business. Common examples include:

• Minority protection agreements – protecting shareholders who own less than 50% of the company.
• Equal shareholding agreements – establishing how decisions will be made where shareholders have equal stakes, particularly if they reach a deadlock.
• Founder or early-stage agreements -clarifying founders’ roles, commitments, share vesting and restrictions.
• Customised private company agreements – covering issues such as buy-sell arrangements, dividends, financing, dilution and the rights of shareholder-directors.

Why is a Shareholders Agreement important?

A well-drafted agreement provides clarity about how the business operates and helps shareholders understand their rights and responsibilities.

It can also establish what happens when circumstances change – for example, when new investors join, further shares are issued or a founder leaves.

Having these arrangements agreed in advance can help prevent misunderstandings and make difficult decisions easier to manage.

What should it include?

A Shareholders Agreement can cover a wide range of issues, including:

• Decision-making and voting rights – including decisions requiring unanimous or majority approval.
• Reserved matters – key decisions requiring shareholder or investor consent.
• Information rights – providing access to financial and business information.
• Share transfers – setting out when and how shares can be sold or transferred.
• Dividend policy – establishing how profits will be distributed.
• Deadlock provisions – dealing with situations where shareholders cannot agree.
• Restrictive covenants – protecting the business from certain competing activities.
• Confidentiality – protecting sensitive business information.
• Dispute resolution – setting out how disagreements can be resolved, potentially through mediation or arbitration.
• Warranties – providing assurances about matters such as the company’s debts and intellectual property.

When do you need one?

There is no legal requirement for a company to have a Shareholders Agreement. However, it can be particularly important when external investors become involved.

It should also be reviewed and potentially updated as the business grows, new investors join, ownership changes or the company’s structure evolves.

Is it legally binding?

Yes. Once signed, a Shareholders Agreement is a legally binding contract, creating enforceable rights and obligations for the parties.

If a new shareholder needs to become bound by the existing agreement, they may need to sign a Deed of Adherence.

Who signs it?

Typically, a Shareholders Agreement is signed by:

• The company
• Existing shareholders
• New investors joining the business

Ideally, all shareholders should sign so that everyone is subject to the same rules and protections, although this can depend on the terms of the agreement.

What happens without one?

Without a Shareholders Agreement, a company relies primarily on its Articles of Association and the Companies Act 2006.

While these provide a framework for running the company, they may not cover the specific protections or arrangements shareholders need.

This can create uncertainty around ownership, decision-making and how disputes should be handled.

Shareholders Agreement vs Articles of Association

The two documents serve different purposes.

Articles of Association set out the company’s internal rules and are publicly filed at Companies House.

A Shareholders Agreement is a private contract that governs the rights and responsibilities of the shareholders.

Together, they can provide a clear framework for how a company operates and how shareholders work together.
