Starting a business with someone else can be one of the smartest (and most rewarding) ways to build something bigger than you could manage on your own. You might bring different skills, share the workload, and split the cost of getting started.
But partnerships can also get messy fast if expectations aren’t written down early. Not because anyone plans for a dispute - but because the day-to-day realities of running a business will eventually force decisions about money, control, time, and risk.
That’s where a well-drafted partnership agreement earns its keep. It’s not “paperwork for the sake of it”. It’s a practical roadmap for how your partnership will actually operate, and what happens when something changes.
Below, we’ll walk through what your partnership agreement should include in 2026, what to think about before you sign, and how to set your business up so you can focus on growth (instead of conflict).
What Is A Partnership Agreement (And Do You Really Need One)?
A partnership agreement is a written contract between business partners that sets out:
- who the partners are,
- how the partnership runs day-to-day,
- how profits and losses are shared,
- how decisions get made, and
- what happens if something goes wrong (or someone wants to leave).
In Australia, partnerships can exist even if you never sign anything. If two or more people carry on a business together with a view to profit, you may already be in a partnership - which means you may already have legal obligations to each other.
If you don’t have a written agreement, the default rules under state and territory partnership laws can apply. The problem is those default rules are usually too general, and they often don’t match how modern businesses operate in practice.
Putting a clear Partnership Agreement in place gives you control over the rules, instead of leaving things to assumptions (or outdated defaults).
Just as importantly, it forces you and your partner(s) to have the conversations most people avoid until it’s too late.
How Do You Decide The Basics: Ownership, Roles, And Contributions?
One of the most common partnership problems we see is that people agree on the “big idea” but never properly agree on the mechanics.
Your partnership agreement should spell out the fundamentals clearly, including:
1) Who The Partners Are (And Whether Anyone Else Can Join)
This might sound obvious, but it matters. The agreement should list the legal names of the partners (and ideally how they’re identified, such as by ABN where relevant).
It should also address:
- whether new partners can be admitted,
- what approvals are needed (unanimous vs majority), and
- what the new partner must contribute (money, clients, IP, time, etc.).
2) What Each Person Is Contributing
Partners often contribute different things, and not all contributions are cash. A partnership agreement should document:
- cash contributions (how much, when it’s due, and whether it can be called back),
- assets contributed (equipment, vehicles, stock),
- intellectual property (like a brand name, designs, software, or a customer list), and
- non-financial contributions (time, expertise, existing client base).
If one partner is contributing significantly more (or doing significantly more work), your agreement can reflect that in how profits are shared or how decisions are weighted.
3) Roles And Responsibilities (So Nobody Is Guessing)
Many disputes are really role disputes in disguise. For example:
- One partner thinks the other is “not pulling their weight”.
- One partner thinks they’re responsible for strategy, while the other starts making big operational decisions.
- Someone assumes the other will handle tax, invoicing, and compliance - and it doesn’t happen.
Your partnership agreement should set out who is responsible for what, including:
- sales and customer management,
- operations and delivery,
- marketing and branding,
- finance and bookkeeping,
- staff management, and
- supplier relationships.
This doesn’t need to be overly rigid, but it should be clear enough that you can hold each other accountable.
How Should Profits, Losses, And Payments Work?
Money is one of the fastest ways to turn a good partnership into a stressful one - especially when the business starts making revenue (or when it stops).
A strong partnership agreement should cover not just “how profits are split”, but the full financial system behind that split.
1) Profit And Loss Sharing
Your agreement should state:
- how profits are calculated (for example, after expenses, wages, tax provisions, and reserves),
- how often profits are distributed (monthly, quarterly, annually, or only when agreed), and
- how losses are shared (and who must cover cash shortfalls).
Don’t assume profits will always match cash in the bank. Many businesses can be “profitable” on paper while still being tight on cash flow (for example, where invoices haven’t been paid yet).
2) Partner Drawings, Salaries, Or Allowances
Some partnerships pay partners a regular “drawing” (a consistent amount paid out to partners), while others only distribute profits periodically. Either can work - but it must be documented.
Your agreement should also address whether partners can be paid differently based on workload (for example, one partner working full-time and one part-time).
3) Capital Calls (When The Business Needs More Money)
Even good businesses need additional funding sometimes. Your agreement should cover what happens when the partnership needs more working capital, including:
- who can request a capital injection,
- how the request is approved,
- whether each partner must contribute equally or proportionally,
- what happens if a partner can’t (or won’t) contribute, and
- whether additional contributions change ownership or are treated as loans.
This is one of those clauses you’ll be very glad you included if a big opportunity (or a big expense) arrives unexpectedly.
How Do You Make Decisions And Manage Risk In A Partnership?
A partnership agreement isn’t just about money - it’s about control, authority, and risk.
Without clear decision-making rules, partners often assume they have the same level of authority in every situation. That can lead to expensive surprises (like one partner signing a contract the other strongly disagrees with).
1) Day-To-Day Decisions Vs Major Decisions
A practical approach is to split decisions into categories:
- Day-to-day operational decisions: handled by the partner responsible for that area (within agreed limits).
- Major decisions: require partner approval (often unanimous, or a specific voting threshold).
Examples of “major decisions” you might want to define include:
- taking on debt or giving guarantees,
- entering long-term contracts,
- hiring senior staff or committing to major payroll costs,
- spending above a certain dollar limit,
- changing the business model, brand, or pricing strategy, and
- selling the business (or a major asset).
2) Authority To Bind The Partnership
In many partnerships, each partner can bind the business in contracts with third parties. That’s a big risk if not managed carefully.
Your partnership agreement can set internal rules about signing authority (for example, requiring two signatures for contracts above a certain value). While this may not always limit what a third party can enforce, it creates clear internal consequences if a partner goes outside agreed boundaries.
3) Confidentiality And Protecting Your Business Information
Partners typically share sensitive information - pricing, margins, client lists, marketing strategy, and supplier terms.
Your agreement should include confidentiality obligations, and you may also want a separate Non-Disclosure Agreement in situations where information is being shared before the partnership is fully formalised (or where you’re discussing projects with contractors and collaborators).
4) Restraints (Non-Compete And Non-Solicit) Where Appropriate
If one partner leaves, you may want protections so they don’t immediately:
- set up a competing business next door,
- approach your existing customers, or
- poach key staff or contractors.
These clauses must be drafted carefully to be enforceable (they generally need to be reasonable in scope, time, and geography). But when they’re appropriate and properly structured, they can make a huge difference to protecting the value you’ve built together.
What Happens If Things Change: Exits, Disputes, And Ending The Partnership?
Most people don’t start a partnership expecting it to end - but businesses evolve, people’s circumstances change, and sometimes partners simply want different things.
It’s much easier to plan for that now, while you’re aligned, than later when emotions are high and the business is under pressure.
1) Exit Events (And What Triggers Them)
Your partnership agreement should define what happens if a partner:
- wants to leave voluntarily,
- becomes ill or can’t work (temporary incapacity),
- passes away,
- becomes bankrupt or insolvent,
- seriously breaches the agreement, or
- acts in a way that damages the business (for example, misconduct or fraud).
For each exit event, clarify whether the partner’s interest can be bought out, whether the partnership ends automatically, and how the business continues (if at all).
2) Valuation And Buyout Mechanisms
This is a critical piece. If a partner leaves, how do you value their share?
Your agreement should cover:
- how the business is valued (agreed formula vs independent valuer),
- whether goodwill is included,
- how debts are treated in the valuation, and
- the payment terms (lump sum vs instalments).
Without a valuation mechanism, buyouts often turn into deadlocks because each side has an incentive to argue for a number that benefits them.
3) Dispute Resolution (So You Don’t Jump Straight To Court)
Disputes don’t always mean the partnership is doomed, but they do need a process. Many partnership agreements include a staged pathway such as:
- good faith negotiation between partners,
- mediation with an independent mediator, and
- arbitration or court as a last resort.
This is about keeping disputes contained, practical, and as cost-effective as possible.
4) How To End A Partnership Properly
Your agreement should explain what happens if the partners decide to wind up the business, including:
- who is responsible for completing work-in-progress,
- how assets are sold or distributed,
- how debts are paid, and
- how customer communications are handled.
It can also help to understand the broader steps involved in ending a business partnership, because the legal and practical issues can be more involved than people expect.
5) When A Partnership Might Not Be The Best Structure
Sometimes, the real solution isn’t a “better partnership agreement” - it’s a different business structure.
For example, if you’re building something with:
- significant risk exposure,
- plans to bring on investors,
- employees and scaling operations, or
- valuable intellectual property,
it may be worth considering a company structure instead. Many founders prefer a company because it can provide limited liability and clearer governance frameworks.
In that case, you may be looking at a Company Set Up with a Shareholders Agreement to manage decision-making, exits, and ownership in a way that’s often more scalable than a traditional partnership.
(This doesn’t mean partnerships are “bad” - it just means the best structure depends on what you’re building.)
Key Takeaways
- A partnership agreement sets the ground rules for ownership, roles, money, decision-making, and exits - and helps prevent misunderstandings turning into disputes.
- Your agreement should clearly document partner contributions (cash, assets, time, and IP), not just the profit split.
- Strong financial clauses cover profit distribution, losses, partner drawings, and what happens when the business needs more capital.
- Decision-making rules should distinguish between day-to-day authority and major decisions, especially where contracts and spending are involved.
- Exit and dispute clauses are essential: valuation methods, buyout terms, mediation pathways, and what happens if a partner can’t continue.
- For some businesses, a company structure with a Shareholders Agreement can be a better long-term fit than a partnership.
