Thinking about updating or fully replacing your company’s Articles of Association? You’re not alone. As your business evolves - new investors, different share classes, or simply a need to tighten governance - you’ll likely need a formal resolution of adoption of Articles of Association.
In the UK, this isn’t just a housekeeping exercise. It’s a legal process with specific voting thresholds, notices, filings and drafting choices that can meaningfully affect control, funding and day-to-day decision-making.
In this guide, we’ll explain when you need a resolution, how to pass it correctly, what to file with Companies House, and the common pitfalls to avoid so your changes take effect smoothly and stand up under scrutiny.
What Is A Resolution Of Adoption Of Articles Of Association?
Your Articles of Association (the “Articles”) are your company’s internal rulebook. They set out how directors make decisions, what rights each class of shares has, how shares can be transferred, and how meetings and votes are run.
When a company decides to replace its existing Articles with new ones (or make substantial changes), shareholders must approve that change by passing a special resolution to adopt the new Articles. Under the Companies Act 2006, changing or adopting Articles generally requires a special resolution - at least 75% of votes cast in favour - unless the Articles are entrenched with stricter requirements.
You’ll sometimes see this called “adopting bespoke Articles,” “adopting amended Articles,” or “adopting new Articles.” In all cases, the outcome is the same: the company replaces its current constitutional rules with a new set agreed by the shareholders.
When Should A UK Company Adopt Or Amend Its Articles?
Model Articles are a sensible default for many private companies at the start. But as your business grows, you may outgrow the Model Articles and need bespoke rules. Common triggers include:
- Raising investment - adding investor protections, information rights, reserved matters and pre-emption rights that suit a funding round.
- Issuing new share classes - creating preference shares, growth shares or non-voting shares, and defining dividends, conversion and liquidation rights.
- Tightening governance - clarifying director appointment/removal, quorum, deadlock procedures, or expanding written decision rules.
- Exit planning - adding drag-along and tag-along provisions to streamline share sales and protect minority shareholders.
- Aligning with your cap table - reflecting changes made since incorporation, and removing outdated provisions that no longer fit.
- Cleaning up inconsistencies - ensuring the Articles and any Shareholders Agreement work together and don’t contradict each other.
If you’re weighing a refresh, it’s a good moment to book an Articles of Association Review so you can tailor the rules to how you actually operate.
What Kind Of Resolution Do You Need, And How Do You Pass It?
Adopting or amending Articles requires a special resolution under section 21 of the Companies Act 2006. Practically, that means at least 75% of votes cast are in favour. The key points to understand are:
Special Resolution Threshold And Form
- Threshold: A special resolution requires a 75% majority of votes cast. If you’re used to ordinary resolutions (simple majority), be careful - this is a higher bar.
- Format: You can pass a special resolution at a general meeting or using a written resolution for private companies. Public companies can’t use written resolutions.
- Wording: The resolution should clearly state that the company is adopting (or amending) its Articles and reference the version/attachment being adopted.
Not sure whether to use a meeting or written resolution? Our explainer on ordinary vs special resolutions outlines the differences and when each approach is appropriate, and this deep-dive on Special Resolutions covers the practicalities of getting the vote right.
Written Resolutions (Private Companies)
- Circulation: The directors propose the resolution and circulate it to eligible members, setting out how to signify agreement and the closing date.
- Timeframe: Members usually have 28 days to respond unless your Articles specify a different period.
- Passing: The resolution passes when the required majority of eligible votes are received in favour within the period.
- Recordkeeping: Keep signed copies and minutes noting when the threshold was met.
General Meetings
- Notice: For a private company, at least 14 clear days’ notice is standard unless your Articles permit shorter notice with sufficient member consent.
- Content: The notice should include the text of the special resolution and the proposed Articles (or a link/access to them).
- Proxies: Members have a statutory right to appoint a proxy. Ensure your notice explains how to do this.
- Quorum & Voting: Check your Articles for quorum rules. Special resolutions need 75% of votes cast in favour.
Board Resolutions Come First
Before going to shareholders, the board should properly approve the proposal to adopt new Articles (or circulate the written resolution). Record this with clear Board Resolutions so there’s a clean audit trail. If you use a template, make sure it suits the scenario and the company’s particular Articles.
Class Consents And Entrenched Provisions
- Class rights: If the change varies or abrogates rights attached to a class of shares, you may also need separate class consent (typically via class meeting or written consent).
- Entrenchment: Some companies adopt Articles with entrenchment (provisions that require more than a special resolution to change). If yours are entrenched, follow the higher consent process set out in the Articles.
The Step-By-Step Process To Adopt New Articles
If you want a clear roadmap, here’s the process most UK private companies will follow.
1) Review Your Current Constitution And Shareholder Arrangements
- Identify gaps in the current Articles compared with how you operate today.
- Map your cap table and existing share classes to ensure the new Articles reflect reality.
- Check any Shareholders Agreement for reserved matters, transfer rights, and vetoes so you don’t create conflicts.
2) Draft The New Articles (Or Specific Amendments)
- Build on the Model Articles or move to fully bespoke Articles, depending on your needs.
- Include practical rules you’ll use: pre-emption on share issues and transfers, drag/tag, director appointment/removal, written resolutions, and deadlock processes.
- If you’re adding new share classes, define voting, dividend, conversion and liquidation preferences clearly.
- Consider how directors execute documents, including any seal provisions and who is authorised to sign - this should align with how you’re executing documents day-to-day.
3) Approve At Board Level
- Hold a board meeting (or written directors’ resolution) to approve the draft Articles and to call a general meeting or circulate a written resolution.
- Authorise a director or the company secretary to finalise documents and file at Companies House.
4) Secure Shareholder Approval (Special Resolution)
- If using a meeting: send the notice, attach or provide access to the proposed Articles, and ensure proxy rights are respected. Record votes and keep minutes.
- If using a written resolution: circulate to members with clear instructions and track responses until the 75% threshold is met.
5) File With Companies House
- Deadline: File a copy of the special resolution and a full copy of the adopted Articles with Companies House within 15 days of the resolution passing.
- Method: Use Companies House WebFiling (or your company agent) and ensure the uploaded Articles match what members approved.
- Accuracy matters: Inconsistencies between the filed Articles and the version approved by members can cause problems later.
6) Update Company Records And Communicate
- Keep an up-to-date copy of the Articles at the registered office or inspection location and make them available to members on request.
- Update internal governance packs and any onboarding materials for new directors or investors.
- Check knock-on changes for share certificates, cap table and any references to Articles in existing contracts.
Drafting Tips: What To Cover In Bespoke Articles
Strong Articles reduce disputes and make growth decisions easier. As you consider an adoption resolution, think about whether your new Articles should include:
- Clear share issue rules - pre-emption on new issues, waiver mechanisms, and pricing safeguards suitable for future funding rounds.
- Transfer controls - good leaver/bad leaver rules, compulsory transfer events, and practical pre-emption timelines.
- Investor protections - matters requiring enhanced consent (e.g. spending caps, changing business, issuing debt, granting security).
- Exit mechanics - drag-along and tag-along rights, fair price protections, and how minority holders get informed.
- Director decision-making - quorum, chair powers, casting votes, and written resolutions for speed.
- Deadlock and dispute resolution - step-in rights, escalation to non-executives, or independent expert determination.
- Authorised signatories - who can sign on behalf of the company and when two signatures are required.
If you operate with multiple founders or external investors, pairing bespoke Articles with a robust Shareholders Agreement is often the best way to cover commercial points that sit more naturally outside the constitution (for example, founder vesting or day-to-day reporting obligations).
Common Pitfalls When Adopting New Articles (And How To Avoid Them)
Most problems we see are preventable with a bit of planning. Watch out for these issues:
- Using the wrong voting threshold - adopting Articles by ordinary resolution instead of a special resolution risks invalidity. Double check the threshold and your Articles before you start.
- Forgetting class consents - if class rights are affected, you may need separate class approval. Skipping this can trigger disputes or even claims for unfair prejudice.
- Misalignment with investor documents - if your Articles conflict with your term sheet or side letter, you’ll face ambiguity at the worst possible time. Align the drafting before the vote.
- Missing filings - you must file the special resolution and the new Articles with Companies House within 15 days. Late filings can create administrative headaches and risk penalties.
- Unclear drafting - vague pre-emption rules or poorly defined leaver provisions create friction later. Professional drafting saves time and protects value.
- No board paper trail - failing to minute the board’s proposal and the shareholder approval can complicate due diligence down the track.
If you’re documenting the company’s decisions at each stage, a tidy set of Board Resolutions and shareholder records makes life much easier in audits, funding rounds and sales processes.
Example Wording For A Special Resolution To Adopt Articles
Every company is different, so treat this as illustrative only - not a template to rely on without legal advice:
“It is resolved as a special resolution that the regulations contained in the document produced to the meeting and initialled by the chair for identification be and are hereby adopted as the Articles of Association of the Company in substitution for and to the exclusion of the existing Articles.”
When using a written resolution, include clear instructions for how members signify agreement, the date by which votes must be received, and attach the full text of the Articles being adopted.
Frequently Asked Questions
Do We Need A Special Resolution For Every Change To The Articles?
Yes. Under the Companies Act 2006, adopting or amending Articles requires a special resolution (75%+ of votes cast). If your Articles include entrenched provisions that require an even higher threshold, you’ll need to follow those stricter rules.
Can A Private Company Use A Written Resolution?
Yes. Private companies can pass special resolutions by written resolution. Follow the statutory circulation and timing rules and ensure the written resolution clearly states that it is a special resolution.
What Do We File With Companies House?
Within 15 days, file a copy of the special resolution and the full, adopted Articles. Make sure the version you file exactly matches the version approved by shareholders.
How Do New Articles Interact With Our Shareholders’ Agreement?
These documents should complement one another. Where there’s a conflict, courts will generally treat the Articles as the company’s constitution and the Shareholders’ Agreement as a private contract among its parties. For that reason, align them carefully. If you’re updating one, review the other at the same time - and consider refreshing your Shareholders Agreement alongside the Articles.
Do We Need A Board Resolution Too?
Yes. It’s good governance to have the board approve the proposal and the logistics (meeting notice or written resolution), and to authorise someone to file documents. Keep a clear paper trail using appropriate board minutes and, if relevant, a directors’ written decision. If you need a quick framework, our Directors’ Resolution Template service can help you formalise those decisions.
Key Takeaways
- Adopting or amending Articles requires a special resolution (75%+). Use a general meeting or, for private companies, a written resolution - and follow the correct notice and voting rules.
- Think strategically about what to include in new Articles: share rights, pre-emption, transfer controls, investor protections, exit mechanics, and director decision-making.
- Align your constitution with any existing Shareholders Agreement to avoid conflicts, and minute decisions with clear Board Resolutions.
- File the special resolution and the adopted Articles with Companies House within 15 days. Keep accurate, signed records of the vote and the final version approved.
- If class rights are affected, obtain the necessary class consents in addition to the special resolution.
- It’s worth getting an Articles of Association Review so your governance framework fits your business today and is flexible for growth tomorrow.
