Partnership Agreements In The UK: What To Include

Thinking of starting or growing a business with one or more co-founders? A well-drafted partnership agreement is one of the most important documents you can have. It sets the ground rules, reduces misunderstandings and protects everyone involved when things don’t go to plan. In short, if you’re searching for “partnership agreement UK,” you’re in the right place.

In this guide, we’ll demystify what a partnership agreement is, how it fits alongside structures like companies and LLPs, what it should include, and the step-by-step process to get yours in place. We’ll also cover common risks and how to manage exits or changes without derailing your business.

What Is A Partnership Agreement In The UK?

A partnership agreement is a contract between two or more people doing business together for profit. While general partnerships in England and Wales are governed by the Partnership Act 1890, that Act contains basic default rules. Those defaults are often not what modern businesses want (for example, equal profit shares regardless of effort or capital, and automatic dissolution if a partner leaves).

That’s why it’s essential to agree clear, tailored terms upfront. A Partnership Agreement lets you choose how profits are split, who makes which decisions, what happens if someone wants to leave, and how disputes are handled. Think of it as your operating manual: it saves you time, reduces conflict, and gives your business stability from day one.

Key points about partnerships under UK law:

• Liability: In a general partnership, partners are usually personally liable for the debts of the business.
• Tax: Partnerships are “transparent” for tax – the partnership files a return, but profits are taxed on the partners individually through Self Assessment.
• Authority: Each partner can bind the partnership in contracts if acting in the usual course of business (unless restricted by agreement and communicated to third parties).
• Default rules: Without a written agreement, the 1890 Act applies by default (equal profits, no salary, all partners can manage, etc.).

If you want more control over these issues, a written agreement is the simplest and strongest way to achieve it.

Partnership Vs LLP Vs Company: Which Structure Fits Your Plans?

Before finalising your partnership agreement, it’s smart to check the structure truly suits your goals. In the UK, you typically have three options if you’re going into business together.

General Partnership

Fast and simple to set up, with minimal filing obligations. However, partners usually have unlimited personal liability, and raising investment can be trickier. A written agreement is highly recommended to avoid the rigid defaults of the 1890 Act.

Limited Liability Partnership (LLP)

An LLP combines partnership-style flexibility with limited liability. Members generally aren’t personally liable for the LLP’s debts beyond their contributions (assuming no wrongful trading, personal guarantees, etc.). You’ll have Companies House filing obligations and will need an LLP agreement (similar in spirit to a partnership agreement). An LLP can suit professional services firms and ventures where liability protection is important.

Private Limited Company (Ltd)

A company has separate legal personality and limited liability for shareholders. It’s often preferred if you’ll seek external investment or plan to scale. Directors manage the company; owners hold shares and may have a Shareholders Agreement to regulate their relationship. There are more formalities, but it can make growth and succession easier.

If you’re weighing up the options, it can help to compare Partnership vs Company and consider when a collaboration might be better structured as a Joint Venture vs Partnership. Choosing the right structure upfront will save you hassle later, so it’s worth getting tailored advice for your plans and risk profile.

What Should A UK Partnership Agreement Include?

Your agreement should be clear, practical and tailored to how you actually intend to operate. The following areas are the ones we see most businesses benefit from locking down early.

1) Business Scope And Roles

• Purpose and permitted activities of the partnership.
• Day-to-day responsibilities (e.g., finance, operations, sales) and any designated managing partner.
• Authority limits (for example, spend thresholds needing approval; contracts above £X require all partners’ sign-off).

2) Capital, Profits And Drawings

• Initial capital contributions, ongoing funding expectations, and treatment of partner loans.
• Profit and loss sharing ratios (they don’t have to be equal, and can vary over time).
• Drawings policy (when and how partners can take money out), and any priority returns.

3) Decision-Making And Voting

• Decisions partners can make unilaterally vs those needing majority or unanimous consent.
• Reserved matters (e.g., taking on debt, hiring key staff, entering long-term leases, major asset sales).
• Meeting procedures and quorum requirements.

4) IP, Confidentiality And Restraints

• Who owns existing and newly created intellectual property.
• Confidentiality obligations during and after the partnership.
• Reasonable non-compete and non-solicit restrictions to protect the business.

5) Onboarding, Exit And Succession

• How new partners can be admitted (including any capital buy-in).
• Voluntary exits, retirement, long-term illness or incapacity, and death of a partner.
• Buy-sell mechanisms, valuation methods, and payment terms for departing partners’ interests.

6) Disputes And Deadlock

• Internal complaints process, mediation and (if needed) arbitration or court jurisdiction.
• Deadlock breakers (chair’s casting vote, independent expert, shotgun/buy-sell clauses).

7) Compliance And Housekeeping

• Banking arrangements, accounting records, and financial reporting.
• Insurance, data protection and regulatory compliance responsibilities.
• Amendment procedures, notices and governing law.

If you want examples of how these points are often drafted, this overview of key partnership clauses is a useful starting point. That said, avoid copy-paste templates – your agreement should match your model, the risks in your industry and how you actually plan to work together.

Step-By-Step: Setting Up A Partnership Agreement

You don’t need to overcomplicate this. A practical process keeps momentum while making sure the important pieces are covered properly.

Step 1: Align On The Commercials

Start with a short discussion paper capturing the core decisions you’ve made: roles, time commitments, capital contributions, profit shares, authority limits, and long-term vision. Treat it like a mini-term sheet – it will make drafting faster and cheaper.

Step 2: Pick Your Structure And Register

Confirm whether you’ll proceed as a general partnership, LLP or company. If remaining as a general partnership, you’ll typically:

• Choose a business name (ensure it’s not infringing anyone’s trade mark and avoid sensitive words).
• Register with HMRC for Self Assessment and a UTR (and VAT if required).
• Open a business bank account.

If you decide a company is more suitable, you’ll also need to consider documents like a Shareholders Agreement and the company’s Articles. If you prefer the simplicity of a sole trader for now, here’s a helpful outline on registering as a sole trader for comparison.

Step 3: Draft Your Partnership Agreement

With the commercial points agreed, get the agreement drafted professionally to capture your intentions clearly and avoid gaps. A legally robust Partnership Agreement will also address what happens if someone leaves or if you need to restrict a partner’s authority for high-value deals with suppliers or landlords.

Step 4: Sort The Practical Policies And Contracts

Depending on your business, you may also need contracts with customers and suppliers, a Privacy Policy if you’re handling personal data, and compliant employment documents when you hire staff. Getting your legal foundations in place early reduces friction as you grow.

Step 5: Sign, Store And Communicate

Circulate the final draft for review, sign it properly (physically or electronically), store it securely, and let relevant stakeholders know any key rules (e.g., who can sign contracts over certain amounts). Revisiting your agreement annually keeps it aligned with how you actually operate.

Common Partnership Risks (And How Your Agreement Protects You)

No one starts a business expecting disputes, but they can happen – often because expectations weren’t clear. Here are the issues we see most often, and how a good agreement helps.

Unclear Profit Splits Or Drawings

Default law splits profits equally regardless of input. If one partner is full-time and another is part-time or contributes capital only, that may feel unfair. Your agreement should lay out profit shares and drawings rules clearly, with flexibility to adjust as roles evolve.

Decision-Making Deadlock

Equal voting sounds fair until you disagree on a big decision. Include reserved matters, practical voting thresholds and a deadlock mechanism so strategic moves don’t grind to a halt.

Unexpected Liability

In a general partnership, one partner’s actions can bind the business. Clear authority limits and internal approval processes reduce the risk of unauthorised commitments and help reassure lenders and suppliers.

IP And Client Ownership

Partners sometimes assume “the business” owns everything, but unless your agreement says so, ownership can be unclear. Expressly assign IP and define who owns client relationships to avoid disputes if someone leaves.

Exit, Death Or Long-Term Illness

Without agreed exit routes and valuation methods, departures can get messy – or even trigger dissolution by default. Build in buy-sell clauses, sensible payment terms and clear triggers (resignation, retirement, death, incapacity) so everyone knows the plan.

Confidentiality And Restraints

It’s reasonable to prevent a departing partner from using confidential information or poaching key staff and clients for a fair period. Tailored non-compete and non-solicit provisions protect the goodwill you’re building.

If any of these risks sound familiar, don’t stress – they’re exactly what a carefully drafted agreement is designed to handle.

Changing, Exiting Or Ending The Partnership

Partnerships evolve. Someone may want to reduce hours, a new partner might join, or the team may decide it’s time to wind down. Your agreement should make those transitions smooth and predictable.

Admitting New Partners

Set a clear process: due diligence, agreement of terms (including capital contribution and profit share), and a deed of accession so the new partner agrees to be bound by the current partnership agreement.

Voluntary Exits And Retirements

Plan ahead for notice periods, handover responsibilities, and how to value and pay out a departing partner’s interest. This is where those buy-sell mechanics earn their keep. If you’re thinking about leaving a partnership, your ongoing liabilities and release from guarantees should also be addressed.

Disputes And Deadlock

If a relationship breaks down, follow the dispute resolution pathway in your agreement (internal steps, mediation, then arbitration or court). A structured process keeps the focus on resolution and business continuity.

Dissolution And Winding Up

Sometimes closure is the right outcome. The law has default rules, but it’s far better to follow a plan you’ve agreed in advance, including notice, settling debts and distributing any surplus. If you need to formally dissolve a partnership or record the terms of the breakup, a tailored Partnership Dissolution Agreement helps minimise risk and future claims.

Quick Compliance Reminders

• Notify HMRC of changes in partners; keep your partnership tax return and partners’ Self Assessment up to date.
• Update banks, key suppliers and insurers if authority or ownership changes.
• Communicate with staff and clients professionally to preserve goodwill.

If you’re unsure whether to restructure instead of dissolve, it may help to revisit whether your collaboration should continue as a partnership or shift to an LLP or company model. In some cases, a limited-term collaboration might be better as a joint venture rather than a permanent partnership – see the comparison of Joint Venture vs Partnership for context.

Key Takeaways

• A partnership agreement lets you replace the Partnership Act 1890’s rigid defaults with rules that actually suit your business – covering profits, roles, decision-making, exits and disputes.
• Choose the right structure for your plans. Consider liability, tax, growth ambitions and investor expectations when weighing a general partnership against an LLP or company.
• Your agreement should address scope and roles, capital and profit shares, authority limits, IP and confidentiality, onboarding and exit, and practical dispute resolution.
• Set your agreement up the right way: align on the commercials, pick your structure, get the document professionally drafted, then sign, store and review it regularly.
• Plan for change. Clear buy-sell terms, valuation methods and notice procedures will make admissions, departures and dissolutions far smoother.
• Avoid generic templates – your risks, industry and goals are unique. A tailored document will protect your business and your relationships as you grow.
