Articles of association set the written rules for running a UK company and form part of its constitution under the Companies Act 2006. A shareholders’ agreement creates private contractual rights between its parties and can add tailored controls, protections and exit rules. Companies should align both documents because conflicting provisions can undermine negotiated rights and disrupt decisions. New shareholders also need to join the agreement expressly if the company expects those terms to bind them.
This article explains how both documents govern a company, how conflicts affect shareholder rights and how ownership changes create additional review requirements.
What are Articles of Association
The Core Governance Document for Your Company
Your articles of association (Articles) are the foundational governance document for your company. They are a requirement under the Companies Act and are publicly listed with Companies House.
The Articles outlines the core rules for how your company operates, including:
- the powers and responsibilities of your directors;
- the process for appointing and removing directors;
- the rights attached to different classes of shares;
- the procedures for holding shareholder meetings; and
- the steps required for significant corporate actions such as issuing new shares, approving share transfers, or winding up the company.
Why Directors Must Follow the Articles
Essentially, your directors have a legal duty to act in accordance with the Articles at all times. However, if your director makes a decision that breaches the Articles or fails to follow a required procedure, that decision will not be valid. The Articles therefore define the boundaries within which your board must operate.
What is a Shareholders Agreement?
A shareholders agreement is a private contract between all shareholders of your company. Unlike the Articles, it is not filed with Companies House and its contents remain confidential.
The shareholders agreement allows shareholders to negotiate and record rights and obligations that go beyond the Articles. This may be tailored to the specific needs of particular shareholder groups, such as founders, investors or minority shareholders.
What a Shareholders Agreement Typically Covers
Common provisions in a shareholders agreement include:
- confirming how shareholders appoint director representatives;
- granting minority shareholders or investors veto rights over key decisions;
- imposing non-compete obligations on departing shareholders;
- including confidentiality obligations for shareholders; and
- setting out a clear process for resolving shareholder disputes.

How Do the Articles and Shareholders Agreement Work Together?
The Articles provide the overarching governance framework whereas the shareholders agreement adds a layer of customised, contractual protection on top of that framework.
For example, your Articles may give directors full authority to enter into contracts on behalf of the company. Your shareholders’ agreement may require certain shareholders to approve contracts above a set value. Both documents can work together when they deal with different issues, but problems arise if they conflict.
“Many companies focus on a supremacy clause and miss the practical gap: a new shareholder may never have agreed to the private contract. Companies should align the documents and complete the deed of adherence before the ownership change takes effect.”
What Happens If Your Articles and Shareholders Agreement Conflict?
If your articles and shareholders’ agreement conflict, the articles will usually take priority under UK law. This is because they are the company’s main legal document. This creates a real legal risk.
For example, your shareholders’ agreement may give an investor a veto right, but if your articles allow the board to act freely, that veto may not work in practice.
How a Supremacy Clause Protects Your Shareholders Agreement
To manage this risk, well-drafted shareholders agreements include a supremacy clause. This clause states that the shareholders agreement takes precedence over the Articles in the event of any inconsistency. It also requires shareholders to amend the Articles to remove any conflict that arises. This clause ensures that you can enforce the rights you negotiate in the shareholders’ agreement.
Why Getting Both Documents Right Matters for Your Business
| The Legal and Commercial Risks of Poor Drafting | If you do not align your articles and shareholders’ agreement, you risk disputes over decision-making and potential shareholder claims. These disputes can be costly and disrupt your business operations. |
| How Properly Integrated Documents Protect You | When you draft and align both documents from the outset, you protect your business. You ensure minority investor rights are enforceable, give your board clarity on when shareholder approval is required and reduce the risk of invalid decisions. You also create a clear framework to resolve disputes before they escalate. |
| When You Should Review Both Documents | If you are preparing for investment, restructuring your shareholding or bringing in new shareholders, you should review both documents together and ensure they align. Do not wait for a dispute to identify gaps or conflicts in your governance documents. |

How to Keep Both Documents Aligned as Ownership Changes
When a new shareholder joins, the company should review both documents before completing the share issue or transfer. The review should confirm that voting thresholds, board appointment rights, reserved matters and transfer restrictions still match.
A shareholders’ agreement only binds its parties. A new shareholder should therefore sign a deed of adherence unless all shareholders replace the agreement. The deed records the new shareholder’s agreement to follow the existing terms. Without that step, the company may assume protections apply when the new shareholder never accepted them.
Ownership changes can shift control. An investor may receive veto rights, a board seat or information rights. The Articles should support any rights that require company action. The shareholders’ agreement should record confidential commercial terms without making them public through the Articles.
Companies should check the documents after a funding round, founder exit, share transfer or restructuring. Compare each approval threshold, notice process and definition across both documents. Update board procedures and shareholder records. LegalVision’s guide to updating shareholders’ agreements after share transfers explains when a deed of adherence may preserve the existing agreement.
Key Takeaways
Your company’s articles of association are the primary, legally binding rules that govern how your business operates. A shareholders’ agreement is a separate private contract that sets out additional, tailored rights between shareholders. If the two documents conflict, the articles will usually prevail unless the shareholders’ agreement requires them to be amended. You should resolve any inconsistencies during drafting to avoid disputes and uncertainty. Aligning both documents ensures clear decision-making and protects all shareholders’ interests.

Frequently Asked Questions
What is the key difference between a company’s Articles and shareholders’ agreement?
The Articles set public constitutional rules for company decisions and operations. A shareholders’ agreement privately records additional rights and obligations between its parties, including vetoes, transfer controls, confidentiality and dispute procedures.
Can a shareholders’ agreement override the company’s Articles?
Not automatically. The Articles govern the company’s constitutional procedures. A shareholders’ agreement can require its parties to follow agreed priorities and amend the Articles when conflicts arise. Companies should align both documents instead of relying on a priority clause alone.
What areas do shareholders’ agreements typically cover?
Shareholders’ agreements commonly address director appointments, reserved matters, veto rights, share transfers, confidentiality, non-compete obligations, exit arrangements and dispute resolution. Companies can tailor these clauses for founders, investors and minority shareholders.
Does a new shareholder automatically join an existing shareholders’ agreement?
No. A shareholders’ agreement only binds its parties. An incoming shareholder should sign a deed of adherence or enter a replacement agreement. The company should also review both governance documents when the ownership structure or balance of control changes.
