Wills vs. Trusts: What's the Difference?

Wills vs. Trusts: What’s the Difference? A Practical Guide for Perth Business Owners and SMSF Clients
Estate planning is about choosing the right legal tools to protect your wealth, minimise tax leakage and keep your business running smoothly. This guide breaks down what wills and trusts actually do, how they work differently, and why those differences matter if you run a Perth business or act as an SMSF trustee. You’ll get clear explanations of a will’s legal effect, how trusts operate during life and after death, probate in Western Australia, SMSF issues such as binding death benefit nominations, and practical guidance on when to use a will, a trust—or both. We also explain the accountant’s role in succession planning, valuation and tax optimisation, and offer a checklist you can use in an initial advisory meeting. By the end you’ll have a straightforward framework to assess privacy, control, asset protection and tax efficiency in the Australian context.
What Is a Will and Why Is It Important in Estate Planning?
A will is a legal document that records your instructions for distributing assets, appointing an executor and naming guardians for minor children. It only takes effect on death. In practice, a will sets out your testamentary wishes for an executor to administer, and courts may need to grant probate to authorise that administration. A properly prepared will gives clear, enforceable directions that reduce family disputes and help executors and trustees make decisions. It’s also important to know a will’s limits—public probate, possible delays, and gaps if you become incapacitated—so you can decide if additional structures like trusts are needed. The next section highlights the key functions to cover when you draft a will.
Wills perform several core roles in estate administration and family protection:
- Appoint an executor to manage and distribute estate assets in line with your instructions.
- Set out specific bequests and percentage shares to minimise ambiguity for beneficiaries.
- Name guardians for minor children to ensure their care is provided for.
These roles explain why a will is central to most estate plans and point to practical execution requirements that must be met under Australian law.
What Are the Key Components of a Valid Will in Australia?
For a will to be valid in Australia it needs testamentary capacity, a clear intention that the document is your will, correct formal execution with the required signatures, and proper witnessing under state rules. If any of these elements is missing the will may be challenged. At the time of signing the testator should understand the nature of the document, the extent of their assets and who might have a claim. Typical clauses include the appointment of an executor, specific and residuary gifts, guardianship clauses and powers to sell or settle assets; each clause should reflect current assets and relationships. Correct witnessing and avoiding informal changes help prevent disputes. Next we outline how probate gives a will legal authority in Perth and the timelines trustees should expect.
How Does the Probate Process Work for Wills in Perth?
Probate in Western Australia is the court process that confirms a will and authorises an executor to administer the estate. It usually starts with lodging an application and the original will with the WA Supreme Court. After lodgement the court verifies documents and there is an advertising period to identify creditors and interested parties. Once probate is granted the executor can collect assets, pay liabilities and distribute what remains to beneficiaries. Timeframes depend on complexity; estates that involve selling business assets or property commonly take several months to over a year, and legal and administrative costs can reduce available liquidity. Being aware of probate timelines and preparing a liquidity plan helps business owners avoid forced sales—one reason many consider trusts for continuity and privacy.
What Is a Trust and How Does It Differ from a Will?
A trust is a legal arrangement where trustees hold legal title to assets for the benefit of designated beneficiaries. A trust can operate during the settlor’s life or be created on death via a testamentary trust. Trustees act under the terms of a trust deed and have fiduciary duties to manage, protect and distribute assets; when assets are properly held in trust they can avoid public probate procedures. Trusts commonly provide privacy, continuity of management through incapacity or death, and greater flexibility in distributions, but they do need correct funding, a clear deed and ongoing administration, which carries costs. The table below summarises common trust types and how they differ in control, timing and typical uses.
| Trust Type | When Effective | Typical Control & Revocability |
|---|---|---|
| Living trust (inter vivos) | During the settlor’s lifetime | Trustees manage assets; often revocable while settlor is alive |
| Testamentary trust | On death via a will | Created by will; trustees control assets after death |
| Revocable trust | During lifetime, revocable | Settlor can amend or revoke; flexible but offers less creditor protection |
| Irrevocable trust | Once established, generally irrevocable | Stronger asset protection and tax certainty; limited ability to amend |
What Are the Main Types of Trusts: Living, Testamentary, Revocable, and Irrevocable?
Living trusts are set up while the settlor is alive and help ensure assets continue to be managed if the settlor becomes incapacitated. Testamentary trusts are created by a will and only take effect on death, often to control distributions for beneficiaries. Revocable trusts let the settlor retain control and change terms during life, which is flexible but may weaken creditor protections. Irrevocable trusts restrict changes and can provide stronger asset protection and tax advantages. In Australia business owners often use discretionary (family) trusts for trading assets and testamentary trusts for tax-efficient distributions to minors. Choosing a trust type depends on priorities like control, privacy, probate avoidance and long-term tax strategy.
What Are the Benefits of a Trust for Asset Protection and Probate Avoidance?

When assets are correctly held by a trust they usually fall outside the deceased’s personal estate, which can reduce or avoid public probate and keep affairs private. For business owners, holding shares or operating assets in a trust can support continuity because trustees can manage or transfer interests without court approval. Discretionary trustee powers may also limit exposure to direct creditor claims in some cases. Trusts enable staged distributions, layered asset protection and flexible tax planning through trustee distribution resolutions, but they only work if deeds are clear and assets are properly transferred into the trust. Good legal and accounting coordination reduces the risk of unintended tax events or administrative disputes.
How Do Wills and Trusts Compare? Key Differences Explained

Wills and trusts differ by timing, control, privacy, probate impact, cost and how they deal with incapacity. A will takes effect on death and usually requires probate, which can make the process public and slower. A living trust operates during life and can allow faster, private management of assets. Control is another difference: a will appoints an executor to distribute assets after death, while a trust gives ongoing management powers to trustees who can act during incapacity and after death. Trusts carry setup and ongoing administration costs but may reduce probate delays and fees; wills are simpler and cheaper to prepare but expose estates to probate timing and costs.
The table below shows how key estate attributes typically map to wills and trusts for a quick comparison.
| Attribute | Will | Trust |
|---|---|---|
| Effective timing | On death | During lifetime (living) or on death (testamentary) |
| Probate requirement | Often requires probate | Often avoids probate when assets are trust-held |
| Privacy | Public court record | Private administration by trustees |
| Control during lifetime | Limited (testator manages until death) | Trustee manages per deed, including during incapacity |
| Cost & complexity | Lower initial cost, potential probate expenses | Higher setup and ongoing costs, possible savings versus probate |
What Are the Differences in Probate, Privacy, and Control Between Wills and Trusts?
Probate formally validates a will and can expose estate details through the court process. Assets held in a trust, by contrast, are typically administered privately by trustees without probate. Control differs in timing: wills set out post-death directions and rely on an executor, while trusts allow trustees to step in during incapacity and continue after death, supporting business continuity. Privacy and speed often lead business owners to prefer trust structures for operating assets, but an improperly funded or poorly drafted trust can negate those advantages and cause probate-like outcomes. That’s why coordinated legal and accounting advice is essential to align ownership title, tax positions and succession goals.
When Should You Use a Will, a Trust, or Both?
The right choice depends on asset complexity, business ownership, family circumstances and tax priorities. Simple estates may be managed with a will alone. Complex holdings and active businesses often benefit from trusts. Choose a will when you need clear bequests and guardianship nominations and probate timing is acceptable. Choose a living trust for continuity, incapacity planning and privacy. Consider a testamentary trust to achieve tax-efficient outcomes for beneficiaries after death. Many estate plans combine a trust with a “pour-over” or complementary will to capture any assets left outside the trust. Start by mapping assets, deciding who should control them if you become incapacitated, and modelling tax outcomes to determine whether a will, a trust or both best meet your goals.
Why Do Perth Business Owners Need to Understand Wills and Trusts?
Perth business owners face extra layers of complexity: company shares, goodwill, leased premises and SMSF interests all need coordinated succession, valuation and liquidity planning to avoid business disruption and unintended tax consequences. Effective planning must address share transfer mechanics, buy–sell agreements, trustee powers to manage or sell business interests, and contingency funding so liabilities can be met without forcing asset sales. Accurate valuation and proactive liquidity planning help ensure fair outcomes for beneficiaries and smooth ownership transitions, particularly where family members or key employees are successors. Because these issues span legal, tax and commercial areas, the next section shows how wills and trusts support practical succession measures.
How Do Wills and Trusts Support Business Succession Planning?
A will can nominate who should receive business interests and can establish testamentary trusts to structure post-death ownership, but probate delays can slow transfers and disrupt continuity. Trusts—especially discretionary or trading trusts—can include succession rules and give trustees power to manage or sell interests without court involvement, enabling smoother handovers. Practical steps include documenting shareholder agreements, aligning trust deeds with business constitutions, and putting liquidity solutions in place such as life insurance arrangements or phased buy-out mechanisms to fund transfers.
OCB Accountants helps Perth business owners model succession scenarios, prepare financial valuations and advise on tax-effective ownership structures to preserve business continuity.

That accountant-led view bridges strategy and implementation to create practical succession plans.
What Are the Tax Implications of Wills and Trusts for Business Assets in Australia?
Capital gains tax (CGT) can apply to transfers of business assets and shares, and the timing and vehicle—whether a will, a testamentary trust or a trust distribution—affect when CGT events occur and what concessions or rollovers may be available. Transfers on death may qualify for CGT rollover relief in certain situations, but trustees and executors must understand cost base adjustments, small business CGT concessions and potential duty or stamp issues depending on asset type and jurisdiction. Trust distributions can create flexible tax outcomes, but incorrect distributions or poor documentation can result in unintended tax liabilities for beneficiaries or the trust. Early valuation, tax modelling and coordinated accountant–lawyer planning reduce the risk of surprise tax events and help design strategies that balance succession objectives, fairness and tax efficiency.
Wills vs Trusts for Perth Business Owners & SMSF | OCB Accountants
SMSF death benefits are governed by the fund’s governing rules and trustee discretions and do not automatically form part of the deceased’s estate unless paid into it. Binding death benefit nominations (BDBNs) can direct trustees to pay benefits to particular dependants or to the estate, so the interaction between BDBNs, will provisions and testamentary trusts must be carefully aligned to achieve intended outcomes. Tax treatment of super death benefits depends on the beneficiary category and whether the payment is a lump sum or a pension, so estate planning needs to consider legal mechanics and tax consequences together. The table below clarifies common SMSF elements and the documents you’ll need to align SMSF outcomes with your broader estate plan.
| SMSF Element | Legal Mechanism | Practical Implication |
|---|---|---|
| Binding death benefit nomination (BDBN) | Directs trustee payment | Ensures trustee pays specified beneficiaries; can override conflicting will instructions if valid |
| SMSF deed & trustee resolution | Governs payment method | Deed determines whether benefits are paid as a lump sum or as a reversionary pension |
| Dependants vs non-dependants | Tax treatment differs | Tax rates vary depending on whether recipients are dependants and whether payments are pensions or lump sums |
How Do Binding Death Benefit Nominations Work with Wills and Trusts?
A binding death benefit nomination tells SMSF trustees to pay death benefits to the nominated people and, when valid, creates a legally binding direction that may override non-binding wishes in a will. BDBNs usually have formal execution requirements and may expire, so trustees must confirm their validity. The key difference is certainty: a valid binding nomination limits trustee discretion and gives clear direction, while a non-binding nomination only guides the trustee. In practice trustees must reconcile BDBNs with testamentary trusts and wills to avoid conflicting instructions—for example, a BDBN naming a beneficiary can prevent funds from entering an estate that a testamentary trust was intended to control. Keeping BDBNs, SMSF deeds and estate documents synchronised is essential to achieve intended outcomes and avoid disputes.
OCB Accountants offers SMSF advisory that coordinates binding death benefit nominations with wider estate planning documents and provides tax modelling to show implications for dependants and non-dependants. We help trustees check nomination validity, align deed provisions and model after-death cashflows to support trustee decisions. This coordination reduces the risk of misalignment between SMSF trustee powers and testamentary arrangements and supports tax-efficient results for beneficiaries.
What Are the Tax and Legal Implications for SMSF Assets in Estate Planning?
Tax outcomes for superannuation death benefits depend on the recipient’s relationship to the member and whether the benefit is paid as a lump sum or a reversionary pension; dependants generally receive more favourable tax treatment while non-dependants may face higher tax rates. Legal steps include checking the SMSF deed allows intended reversionary pensions, ensuring trustees pass the required resolutions when a member dies, and confirming binding nominations are valid under the deed and legislation. Strategies such as reversionary pensions, testamentary trusts and timely binding nominations can improve tax outcomes, but they must be balanced against trustee duties and wider succession objectives. Close collaboration between accountants and lawyers ensures the SMSF deed, trustee resolutions and wills work together to deliver legally compliant and tax-aware results.

Frequently Asked Questions
1. What are the main advantages of using a trust over a will for estate planning?
Trusts provide key advantages around privacy and continuity. Unlike wills, which enter the public record through probate, trusts are administered privately by trustees. Trusts also allow for ongoing management if the settlor becomes incapacitated and can speed distributions to beneficiaries. Their flexibility supports staged payments for minors or tailored asset protection strategies—though they must be properly funded and administered to work as intended.
2. How can business owners ensure their estate plans are tax-efficient?
Business owners should start with valuation and tax modelling to understand CGT implications and other tax exposures when transferring business assets or shares. Trust structures can offer tax planning opportunities through discretionary distributions, but they require careful documentation and timing. Working with both an accountant and a lawyer ensures your estate plan aligns with current tax rules and delivers the best possible financial outcomes for beneficiaries.
3. What role do binding death benefit nominations play in estate planning?
Binding death benefit nominations (BDBNs) are important for directing how superannuation death benefits are paid. When valid, a BDBN gives trustees a legally binding instruction to pay benefits to specified beneficiaries and can override conflicting provisions in a will. That certainty helps avoid disputes and ensures superannuation assets are handled as you intend.
4. Can a will and a trust work together in an estate plan?
Yes. A common approach is to use a “pour-over” will that directs any assets not already in a trust into the trust on death. This helps ensure all assets are managed under the trust’s terms and combines the benefits of both instruments—clear testamentary directions and private, controlled administration.
5. What should business owners consider when choosing between a will and a trust?
Consider the complexity of your assets, family circumstances and your distribution goals. If your estate includes business interests or complex assets, a trust may better support continuity and privacy. For straightforward estates, a will may be sufficient. Also weigh probate timelines, costs and whether you need guardianship arrangements for minors when making your choice.
6. How do trusts help in managing assets during incapacity?
Trusts allow appointed trustees to manage assets according to the trust deed if the settlor becomes incapacitated. That continuity minimises disruption to asset management and business operations and avoids the need for court intervention or probate-related delays.
7. What are the common pitfalls to avoid when setting up a trust?
Common mistakes include failing to transfer assets into the trust, drafting unclear trust deeds, and not coordinating the trust with wills or binding death benefit nominations. An unfunded trust can be ineffective, vague deed terms can cause disputes, and misaligned documents can lead to conflicting directions. Engaging both legal and financial professionals during setup mitigates these risks and helps ensure the trust works as intended.
Conclusion
Knowing the differences between wills and trusts helps Perth business owners and SMSF trustees build estate plans that protect assets, preserve privacy and manage tax outcomes. Using the right combination of instruments—supported by coordinated legal and accounting advice—creates clearer, more reliable succession plans.
