A shareholder agreement protects your business by setting out exactly how decisions will be made, how shares can be sold, and what happens if a shareholder leaves. It provides clarity, fairness, and structure — giving investors and founders confidence in how the company operates.
At Persona Finance, we help businesses across the UK, EU, and UAE draft, review, and manage shareholder agreements that support growth and reduce disputes.
What Is a Shareholder Agreement?
A shareholder agreement is a private contract between a company’s shareholders that outlines how the business will be run and how key decisions are made. It governs share ownership, voting rights, dispute resolution, and exit strategies.Unlike the Articles of Association, which are public and legally required, a shareholder agreement is confidential and flexible. It allows shareholders to create tailored rules that suit the company’s specific needs.
What does a shareholder agreement do?
A shareholder agreement sets out each shareholder’s rights and obligations, defines how profits and shares are distributed, and establishes procedures for disputes, funding, and ownership changes.
Is a Shareholder Agreement Legally Required in the UK?
A shareholder agreement is not a legal requirement, but it is one of the most important documents a company can have when there is more than one shareholder.Do I need a shareholder agreement for my new business?
Yes, if you have more than one shareholder, you should have one from the start. It prevents disputes, protects minority interests, and provides a clear roadmap for exits, funding rounds, or share sales.
Without one, you rely solely on company law and the default Articles of Association — which are often too generic to handle real-world business conflicts.
Articles of Association vs Shareholder Agreement
Many new businesses assume the Articles of Association provide enough protection, but they serve a different purpose.- Articles of Association: A public document registered with Companies House that outlines governance basics, director duties, and share issuance rules.
- Shareholder Agreement: A private, flexible contract among shareholders that adds detailed, enforceable protections.
What is the difference between the Articles of Association and a shareholder agreement?
The Articles govern the company as a legal entity, while a shareholder agreement governs the relationship between the owners. Together, they ensure clarity, control, and accountability.
Key Clauses Every Shareholder Agreement Should Include
A well-drafted agreement should be practical, clear, and balanced. Below are the core provisions every business should consider.1. Decision-Making and Reserved Matters
List which decisions require unanimous or majority approval — for example, new share issues, borrowing, hiring directors, or selling assets.2. Pre-Emption Rights
Protect existing shareholders by giving them the first opportunity to buy new shares before they are offered externally. This prevents unwanted dilution of ownership.3. Drag-Along and Tag-Along Rights
These clauses simplify company sales:- Drag-along allows majority shareholders to compel minority owners to sell during a full business sale.
- Tag-along ensures minority shareholders can sell their shares on the same terms as the majority.
4. Leaver and Vesting Provisions
Define what happens if a shareholder leaves the company. A “good leaver” (for example, due to illness) may retain fair value, while a “bad leaver” (resignation or misconduct) may be required to sell shares back at a reduced price.5. Dividend Policy
Set expectations on how profits will be distributed or reinvested to avoid conflict over company earnings.6. Dispute Resolution
Establish a clear process for resolving disagreements — for example, mediation followed by arbitration — before resorting to legal action.7. Confidentiality and Non-Compete Clauses
Protect company secrets and prevent shareholders from starting or joining competing ventures during and after involvement with the business.8. Share Valuation Method
Set how shares will be valued if they are bought or sold, typically by independent valuation or an agreed formula.A well-crafted shareholder agreement balances flexibility with protection, providing a structure that works during both growth and conflict.
What Happens If You Do Not Have a Shareholder Agreement?
Many founders postpone drafting an agreement until a dispute arises — by then, it is too late.Without one:
- There may be no procedure for selling or transferring shares.
- Minority shareholders might block major business decisions or sales.
- Departing employees could retain shares indefinitely.
- Investor trust and future funding opportunities could be lost.
- Disputes can escalate into expensive legal proceedings.
What happens if there is no shareholder agreement?
The company defaults to basic company law and standard Articles of Association, leaving gaps around share transfers, exits, and conflict resolution — often resulting in delays, stalemates, or court disputes.
Funding Rounds and Investor Considerations
As your company grows, new investors may require their own protections through an Investor or Subscription Agreement. However, the shareholder agreement remains the foundation for all ownership rules.It can include:
- Pre-emption rights on new shares to protect existing shareholders.
- Anti-dilution provisions to preserve ownership value.
- Information rights for regular access to company performance data.
- Board and observer rights for strategic decision-making.
How Minority Shareholders Are Protected
Minority shareholders (those holding less than 50 percent of shares) often have limited power in company decisions. A shareholder agreement can correct this imbalance.Common protections include:
- Tag-along rights ensuring fair sale opportunities.
- Veto rights over major business changes.
- Access to company information to monitor decisions.
- Clear dispute resolution channels to avoid deadlock.
When Should You Create or Update a Shareholder Agreement?
The best time to create a shareholder agreement is before or immediately after incorporation, when expectations are aligned.You should also review or update the agreement when:
- New shareholders join the company.
- Investment rounds introduce new capital or classes of shares.
- Founders leave, or employees receive equity.
- The business model or ownership structure changes.
Can a single shareholder have an agreement?
While unnecessary for sole ownership, it becomes essential the moment another shareholder or investor is introduced.
