You’ve built a successful business with your partners. You trust each other, complement each other’s strengths, and are working toward a shared vision. But what happens if one of you unexpectedly dies, becomes seriously ill, gets divorced, wants out — or worse, you no longer see eye-to-eye?
It’s a confronting thought, but not preparing for these events can leave your business, your wealth, and your legacy exposed. That’s where a buy-sell agreement comes in — an often overlooked but essential piece of the business continuity puzzle.
What is a buy-sell agreement?
A buy-sell agreement is a legally binding contract between business partners that outlines what happens to each person’s share of the business if certain trigger events occur. Think of it as a “business will.”
These events typically include the seven Ds: death, disability, divorce, departure, disagreement, default (i.e. bankruptcy) and deadlock.Rather than leaving business continuity to chance, the agreement creates a clear roadmap — deciding who can buy the exiting owner’s share, how much it will cost, and how the transaction will be funded.
Why buy-sell agreements matter
A properly structured buy-sell agreement can mean the difference between an orderly transition and a devastating financial and legal mess.
Imagine this scenario: Two long-time business partners, Rekha and Daniel, co-own a thriving digital marketing agency in Sydney. They’ve grown the company steadily for 15 years, share equal ownership, and have no succession plan in place. One morning, Daniel suffers a sudden stroke and can no longer work. His spouse, now managing his affairs, assumes she will take his place in the business.
But Rekha and Daniel’s wife have very different visions for the company — and different risk tolerances. Without a buy-sell agreement, Rekha is left in a tug-of-war over decision-making, while also navigating Daniel’s exit and the business’s future alone.
With a buy-sell agreement in place, the process could have been straightforward. Daniel’s share would be valued according to a pre-agreed method, Rekha would buy his share (funded by insurance), and the transition would be clear, fair and respectful.
It’s not just about protecting the business — it’s about protecting your relationships, your family, and your finances.
Key components of a solid buy-sell agreement
Trigger events
Clearly define the situations that activate the agreement. These might include permanent disability, death, bankruptcy, retirement, voluntary exit, or irreconcilable disputes.
Valuation method
Agree upfront on how the business will be valued. Common approaches include a fixed value (updated annually), a valuation formula, or independent appraisal. Each has trade-offs between simplicity and accuracy.
Funding strategy
Insurance is the most common mechanism for funding the buy-out, but it’s not the only one. Alternatives include company profits, sinking funds, or external finance. The key is ensuring the money will be there when needed, without creating financial strain.
Insurance must be carefully structured to ensure the correct policy owner (business vs. individual), tax-effective outcomes (e.g. no CGT on policy proceeds if owned personally), and clear nomination of the beneficiary.
Non-compete clauses
These prevent outgoing owners from setting up a rival business or poaching clients. While often overlooked, they’re critical in protecting the business’s value and competitive edge.
Right of first refusal
This gives remaining owners the first opportunity to purchase the exiting owner’s share, reducing the risk of an unwanted third party entering the business.
Common pitfalls to avoid
Many business owners assume their shareholders’ agreement or partnership deed already covers succession planning. Often it doesn’t, or it does so inadequately.
Other traps include:
- Failing to regularly update valuations
- Not reviewing insurance cover in line with business growth
- Overlooking personal issues like estate planning or divorce settlements
- Not formalising discussions legally
A buy-sell agreement is only useful if it’s current, funded, and legally enforceable.
The hidden opportunity: business harmony
Beyond legal protection, a well-structured buy-sell agreement can actually enhance trust between partners. When everyone knows the rules and feels protected, it creates space to focus on growth — not what-ifs.
It also gives family members peace of mind. According to CPA Australia, 69% of small business owners do not have a documented succession plan. Without one, the business and the family wealth it represents can be put at significant risk.

Frequently asked questions
What is a buy-sell agreement in business?
A buy-sell agreement is a legally binding contract between business owners that outlines what happens if one owner exits the business due to death, disability, retirement, divorce, or dispute. It sets out who can buy the departing owner’s share, how it will be valued, and how the buyout will be funded.
Why do I need a buy-sell agreement for my business?
Without a buy-sell agreement, your business may face uncertainty, legal disputes, or financial strain if a partner exits unexpectedly. A well-structured agreement ensures a smooth transition, protects remaining owners, and avoids unwanted third parties entering the business.
How is a buy-sell agreement funded?
Buy-sell agreements are typically funded using life and total permanent disability (TPD) insurance policies. This ensures the funds are available when needed without draining business resources. The policy structure (business-owned vs. personally owned) must be carefully planned to ensure tax efficiency and legal clarity.
What are the key events that trigger a buy-sell agreement?
Common trigger events include death, permanent disability, serious illness, divorce, voluntary exit, bankruptcy, or disputes between business partners. These “seven Ds” form the foundation of most buy-sell agreements and ensure the business is protected in a wide range of scenarios.
