Shareholder Agreement Template for UK Agencys

If you run a UK agency with more than one founder or investor, you need a shareholder agreement — and a shareholder agreement template built for agencys specifically. Generic templates miss the things that actually matter in agency structures: what happens when a co-founder leaves mid-project, how client relationships are protected, who controls creative decisions, and how equity splits work when the business is largely people and retainers rather than hard assets. This page explains what a solid shareholder agreement template for a UK agency must include, where off-the-shelf documents fall short, and how Atornee helps you generate a document that reflects how your agency actually operates. We are not a law firm and this is not legal advice — but we can help you get a well-structured starting point quickly, and we will tell you honestly when you need a solicitor to review what you have.

Why this matters

Most agency founders sort out equity on a handshake or with a free template downloaded from a random website. That works fine until it does not — a co-founder wants out, a client relationship becomes disputed, or someone disagrees on whether to take outside investment. At that point, a vague or generic shareholder agreement creates real problems. Agency businesses have specific dynamics: revenue is tied to people, not products; client relationships have real value; and decision-making on pitches, hires, and pricing needs to be clear. A template that was written for a SaaS startup or a property company will not cover any of that properly.

The Atornee approach

Atornee lets you generate a shareholder agreement tailored to a UK agency context — not a one-size-fits-all document. You answer questions about your agency structure, share split, decision-making preferences, and what should happen if a shareholder leaves or wants to sell. The output reflects those answers. It is not a solicitor, and it does not replace one for complex situations, but it gives you a properly structured draft that covers the clauses agency founders actually need — faster and cheaper than starting from scratch or paying for a full bespoke drafting session before you even know what you want.

What you get

A shareholder agreement draft structured for UK agency businesses, covering equity, roles, and decision-making rights
Leaver provisions that address what happens when a founder or shareholder exits — including good leaver and bad leaver distinctions
Client relationship and non-compete clauses relevant to agency work, where people and relationships are the core asset
Dividend policy and profit distribution terms that reflect how agencies typically manage cash flow
Drag-along and tag-along rights so you are covered if the business is ever sold or takes on outside investment

Before you sign checklist

1
1. Agree your share split with co-founders before you start — the agreement documents what you have decided, it does not make the decision for you
2
2. List every shareholder and their role in the business, including whether they are active in the agency day-to-day or purely investors
3
3. Decide which decisions require unanimous consent versus a simple majority — this is where most agency co-founder disputes start
4
4. Think through your leaver scenario: what should happen to shares if someone resigns, is dismissed, or becomes ill
5
5. Consider whether any shareholders have existing client relationships that need to be addressed in non-solicitation clauses
6
6. Generate your draft using Atornee and read it carefully before sharing with co-founders
7
7. If your structure is complex — multiple share classes, external investors, or significant assets — have a UK solicitor review the final document before signing

FAQ

Do I legally need a shareholder agreement for my UK agency?

No, it is not a legal requirement. But without one, your agency falls back on the Companies Act 2006 and your articles of association as defaults — and those defaults often do not reflect what founders actually want. A shareholder agreement gives you control over things the law does not automatically sort out, like what happens when someone leaves or how profits are split.

Can I use a free shareholder agreement template for my agency?

You can, but most free templates are generic and miss clauses that matter specifically to agencies — things like client relationship protections, IP ownership for work created by shareholders, and leaver provisions tied to ongoing client retainers. A free template is better than nothing, but it is worth using one that has been built with agency structures in mind.

What is the difference between a shareholder agreement and articles of association?

Articles of association are a public document filed at Companies House that sets out the basic rules for how your company is run. A shareholder agreement is a private contract between shareholders that can go into much more detail — and it stays confidential. Most agencies need both, and they should be consistent with each other.

What should a shareholder agreement for a UK agency include that others might not?

Agency-specific clauses include: non-solicitation of clients and staff if a shareholder leaves, clarity on who owns client relationships and creative IP, provisions for what happens to ongoing retainers if the business splits, and decision-making rights over pitches or major hires. Standard templates often skip these entirely.

Do I need a solicitor to draft or review my shareholder agreement?

For straightforward two-founder agencies with simple equity splits, a well-structured template reviewed carefully by both parties may be sufficient to start. But if you have multiple share classes, external investors, complex leaver terms, or significant assets tied to the business, a UK solicitor review is worth the cost. Atornee helps you get a solid draft — a solicitor helps you make sure it is watertight for your specific situation.

Can a shareholder agreement be changed after it is signed?

Yes, but all shareholders typically need to agree to any changes, and the amendment should be documented in writing and signed by all parties. This is why getting the agreement right at the start matters — it becomes harder to change once the business is running and relationships are more complicated.
