Do I Need A Partnership Agreement With A Friend?

byAlex Solo11 min read

Do I need a partnership agreement if I'm starting a business with a friend? Yes, in most cases you should have one, even if you trust each other completely.

Starting a business with a friend can be exciting because you already have trust, history and shared energy. The tricky part is that friendship can make the business conversations feel awkward, so people often leave the big decisions until later.

The good news is that a partnership agreement doesn't need to make things formal in a cold way. Done well, it's a practical set of rules that protects the friendship, protects your business and gives you both a clear plan if things change.

Do I Need A Partnership Agreement If We're Friends?

Yes, you usually do need a partnership agreement if you and a friend are running a business together and sharing profits, responsibilities or decision-making.

In England and Wales, an ordinary partnership can exist even if you never sign anything. If you're carrying on a business together with a view to making profit, the Partnership Act 1890 may apply. That means default legal rules can fill the gaps if you haven't agreed your own.

Those default rules are rarely tailored to how friends actually run a modern small business. For example, unless you agree otherwise, the starting point under the Partnership Act 1890 is that partners share profits equally. That might be fine for a true 50/50 business, but it can feel unfair if one person has put in more money, more time or more equipment.

A written agreement helps you answer questions before they become stressful, such as:

  • Who owns what percentage of the business?
  • How are profits, losses and drawings handled?
  • Who can sign contracts or commit the business to spending money?
  • What happens if one of you wants to leave?
  • What happens if the friendship changes but the business still has customers, staff or debts?

This isn't about assuming things will go wrong. It's about making sure you're both clear while things are going well, so you don't have to guess later.

What Can Go Wrong Without A Written Agreement?

Without a written agreement, you may end up relying on default legal rules, memory and assumptions, which can lead to expensive and very personal disputes.

The most common problem is that friends often have different pictures in their heads. One of you might think you're equal partners. The other might think they're the main owner because they paid for the website, the van or the first stock order.

Here are some practical issues that can come up:

  • Ownership: You might disagree about whether the business is 50/50, 70/30 or something else.
  • Drawings: One of you might take money out of the business for living costs while the other thinks all cash should stay in the business.
  • Decision-making: You might not know whether both of you need to approve hiring staff, taking a loan or signing a supplier contract.
  • Workload: One person might slowly take on more hours while profits are still split equally.
  • Exit: If one of you wants to leave, you might not have a method for valuing their share or transferring customers, assets and social media accounts.
  • Liability: In an ordinary partnership, partners can be personally exposed to business debts and obligations. A partner may also be able to bind the business when dealing with customers or suppliers.

Say Maya and Josh start a small events business. Maya pays £6,000 for equipment and Josh manages sales. They don't write anything down because they're close friends. Six months later, the business has £18,000 in the bank, but Maya wants to recover her £6,000 first while Josh expects a 50/50 split of available profits. Neither view is silly, but without written terms, the conversation can quickly become a dispute about fairness rather than a simple check of the agreement.

Is A Partnership Agreement The Right Document For Our Business?

It depends on your business structure, because a partnership agreement is usually for an ordinary partnership, not every type of business run by two people.

Before you draft anything, check what structure you're actually using or planning to use.

Ordinary Partnership

An ordinary partnership is a common setup where two or more people run a business together for profit. You don't register the partnership at Companies House, although you'll usually need to deal with HMRC registrations and partnership tax returns.

For this structure, a partnership agreement is the key document. It sets out how the partners share ownership, profits, duties, liabilities and exit rights.

Limited Company

If you form a limited company, the company is registered at Companies House under the Companies Act 2006. The owners usually hold shares and act as shareholders, directors or both.

In that case, you usually need a shareholders agreement, not a partnership agreement. Your company's articles of association also matter, because they set out internal rules for how the company is run.

Limited Liability Partnership

A limited liability partnership, often called an LLP, is registered at Companies House and is governed by LLP legislation, including the Limited Liability Partnerships Act 2000. It can suit some professional or joint venture style businesses.

For an LLP, you usually need an LLP agreement. This deals with member contributions, profit sharing, management, exits and what happens if a member leaves.

If you're not sure which structure fits your plans, get advice before you sign contracts, open bank accounts or start taking customer payments. Changing structure later is possible, but it can be messy if assets, leases, staff or intellectual property have already built up in the wrong place.

What Should A Partnership Agreement With A Friend Include?

A partnership agreement should include the practical rules for how you'll run, fund, grow and exit the business.

Templates can be a useful starting point, but they often miss the details that matter most between friends. A lawyer should tailor the document before you use it, especially if you'll have staff, a lease, valuable intellectual property, uneven contributions or personal guarantees.

Here's a fill-in outline you can use to prepare for the conversation:

  1. Partners And Business Details: Write the legal names of each partner, the trading name, business address and start date.
  2. Business Purpose: Describe what your business does and whether either of you can run competing projects on the side.
  3. Capital Contributions: Record who is putting in cash, equipment, stock, loans, intellectual property or unpaid work.
  4. Ownership And Profit Shares: State whether profits and losses are split equally or by another percentage.
  5. Drawings And Salaries: Set rules for taking money out, including timing, caps and approval requirements.
  6. Roles And Time Commitments: List who handles sales, operations, finance, staff, admin, marketing and supplier management.
  7. Decision-Making: Separate everyday decisions from major decisions that need unanimous approval.
  8. Banking And Spending Limits: Set who can access accounts, approve payments and sign contracts.
  9. Intellectual Property: Confirm who owns the brand, logo, website, content, customer lists and software.
  10. Confidentiality: Protect business plans, pricing, supplier details and customer information.
  11. Disputes: Set a process for raising issues, meeting, mediation and next steps if you can't agree.
  12. Exit And Buyout: Explain what happens if someone leaves, becomes ill, dies, is removed or wants to sell their share.
  13. Ending The Partnership: Set rules for partnership dissolution, winding down, paying debts and dividing remaining assets.

Make the document specific enough that you can actually use it. For example, rather than saying, partners will agree on spending, say that either partner can approve business spending up to £500, but anything above £500 needs written approval from both partners.

How Should We Handle Money, Drawings And Ownership?

You should agree money rules in writing before the business starts making regular income, because cash is where many friend partnerships become tense.

There are a few separate concepts that often get mixed together:

  • Capital contribution: The money, assets or equipment each person puts in at the start or later.
  • Ownership share: Each person's agreed interest in the business.
  • Profit share: How profits are split after business expenses.
  • Drawings: Money a partner takes out of the business during the year.
  • Loans: Money one partner lends to the business, which may need to be repaid before profit is shared.

For example, Priya and Ben start a food stall. Priya contributes £12,000 for equipment and fit-out costs. Ben contributes £3,000 and works two extra days a week handling events. They agree Priya's £12,000 is a partner loan, not a larger ownership share. The business repays Priya £1,000 per month for 12 months if cash flow allows. After expenses and that repayment, profits are split 50/50 because they both want equal ownership.

That outcome may suit them, but a different business might choose a 70/30 profit split until unequal contributions are balanced. Another might pay one partner a fixed monthly amount for extra operational work before splitting remaining profit.

Your agreement should also cover:

  • Whether drawings need both partners' approval
  • Whether each partner can claim expenses, and what evidence is needed
  • Whether profits are distributed monthly, quarterly or at year end
  • What happens if the business makes a loss
  • Whether partners must contribute more money if the business needs cash

You should also speak to an accountant about tax treatment, HMRC registrations and record-keeping. Legal terms and tax treatment need to work together, especially where partner loans, drawings and profit allocations are involved.

How Do We Make Decisions Without Damaging The Friendship?

You can protect the friendship by agreeing decision rules that are clear, fair and realistic for day-to-day business.

Not every decision should need a formal meeting. If both of you need to approve every stationery order, the business will slow down. On the other hand, one partner shouldn't be able to take out finance, hire staff or sign a long lease without the other's consent.

A helpful approach is to split decisions into three levels.

Everyday Decisions

These are low-risk decisions within an agreed budget, such as buying supplies, responding to customer enquiries or booking routine marketing activity. You can allow either partner to make these decisions alone.

Significant Decisions

These might include spending above a set amount, hiring a contractor, changing suppliers, launching a new product line or entering a customer contract above a certain value. You might require both partners to approve these by email or message.

Major Decisions

These are decisions that can change the business, such as taking a loan, signing a lease, giving a personal guarantee, employing staff, selling assets or the business, changing the business model or admitting a new partner. These should usually need unanimous written approval.

Your agreement should also say what happens if you're deadlocked. For example, you might require a meeting within 7 days, then mediation if there's no agreement within 14 days after that. If the issue still can't be resolved, your exit clause should give you a way to separate without freezing the business indefinitely.

It also helps to schedule a regular business meeting, even if you're friends who speak every day. Keep short written notes of decisions about money, contracts, hiring, suppliers and customer issues. If memories differ later, those notes can save a lot of stress.

What Happens If One Of Us Wants To Leave?

Your partnership agreement should set out an exit process, because one partner leaving can affect customers, suppliers, staff, debts and the value of the business.

Without an exit clause, leaving can become emotional and uncertain. One person may want cash immediately. The other may want time to keep trading. If you have a lease, supplier contract or employee, you may not be able to simply walk away.

A good exit clause should cover:

  • How much notice a partner must give before leaving
  • Whether the remaining partner has the first right to buy the leaving partner's share, and how any partner buyout will work
  • How the business will be valued
  • Whether payment is made upfront or by instalments
  • What happens to business names, domain names, social media accounts, customer lists and goodwill
  • Whether the leaving partner can compete with the business after leaving
  • Who remains responsible for debts, guarantees, leases and supplier obligations

Be careful with restraints on competition. They need to be reasonable to have the best chance of being enforceable, including in scope, area and time. A blanket ban that stops someone earning a living is much harder to justify than a narrow restriction protecting real customer relationships or confidential information.

You should also plan for serious events that no one likes to talk about, including long-term illness, death, bankruptcy or serious misconduct. These clauses can feel uncomfortable, but they make things clearer for everyone if something unexpected happens.

If an issue has already come up, pause major spending and keep records of bank transactions, customer communications, supplier contracts and messages about the dispute. Then get tailored advice before removing money, locking your friend out of accounts or telling customers the partnership has ended.

How Much Does A Partnership Agreement Cost?

The cost depends on how simple the business is, how many partners are involved and how much tailoring your agreement needs.

A very simple two-person partnership with equal contributions and no staff, lease or major intellectual property will usually be more straightforward than a business with unequal investment, personal guarantees, complex profit arrangements or regulated industry obligations.

You generally have three options:

  • Free Template: This can help you start the conversation, but it may not deal properly with your structure, tax setup, decision rules, exits or intellectual property. It can also include clauses that don't fit UK law or your business model.
  • Online Fixed-Fee Legal Service: This can give you a tailored document and upfront pricing, which is often helpful when you're trying to manage startup costs.
  • Traditional Hourly Billing: This can suit more complex matters, but the final cost may be less predictable if there are several rounds of negotiation or restructuring questions.

Whatever option you choose, check what's included. Ideally, your package should cover a discussion about your business structure, a tailored agreement, key clauses on money and exits, and time for you to ask questions before signing.

If you're still deciding whether to operate as a partnership, limited company or LLP, deal with that first. The right document depends on the structure, and using the wrong agreement can create confusion rather than certainty.

Key Takeaways

  • You usually need a written agreement when starting a business with a friend, even if the relationship is strong.
  • An ordinary partnership can exist without a signed document, and the Partnership Act 1890 default rules may not match what you intended.
  • Your agreement should cover ownership, profit sharing, drawings, decision-making, spending authority and exits.
  • If you're using a limited company or LLP, you may need a shareholders agreement or LLP agreement instead.
  • Clear money rules and exit terms can protect both the business and the friendship.
  • Templates can help you prepare, but your final agreement should be tailored to your structure and plans.
