For most Australians with a modest estate and adult beneficiaries, a simple will does the job. If you have minor or vulnerable beneficiaries, a blended family, a business, or genuine asset protection needs, a testamentary trust is worth serious consideration in the simple will vs trust decision.
A simple will costs less and finishes probate faster. A testamentary trust costs more upfront and carries ongoing trustee duties, but it buys control and protection a simple will cannot.
- Gather your asset list, family structure details, and any existing super nominations
- Book a consultation to test your situation against both options before you draft anything
Key Takeaways
A simple will suits modest, uncomplicated estates, while a testamentary trust protects minors, vulnerable beneficiaries, and assets from creditor or relationship risk at a higher ongoing cost.
| Point | Details |
|---|---|
| Simple wills suit simplicity | Adult beneficiaries and modest estates rarely need more than a straightforward will and executor appointment. |
| Trusts protect, but at a cost | Testamentary trusts add asset protection and tax flexibility but require ongoing trustee administration and returns. |
| Super sits outside your will | Superannuation death benefits bypass a will unless a valid binding nomination is in place. |
| Amendments differ after death | A will can be freely redrafted while alive; a testamentary trust’s terms only start evolving once it activates on death. |

Simple will vs testamentary trust: the plain-English difference
A simple will names an executor, appoints guardians for children, and hands assets straight to named beneficiaries once probate finishes. It is typically sufficient for uncomplicated estates, and it is quicker and cheaper to administer than a trust structure.
It suits estates with adult beneficiaries who can manage an inheritance outright, no complicated family dynamics, and no pressing need to shield assets from creditors or a future relationship breakdown.
- Pros: lower drafting cost, faster estate administration, simpler for executors to run
- Cons: no ongoing control once assets transfer, no built-in asset protection, limited flexibility for tax planning
Where a simple will falls short is control after death. Once a beneficiary receives their inheritance, it becomes part of their own estate, exposed to their creditors, their marriage, and their own decisions.
What a testamentary trust actually is
A testamentary trust is created inside your will but only springs into life after you die. It does not operate while you are alive. Trustees then hold and manage assets for beneficiaries under discretionary powers set out in the will, rather than handing everything over in one lump sum.
This structure can provide asset protection and tax flexibility that a simple will cannot offer, because the trustee controls timing and distribution rather than the beneficiary receiving assets outright.
- Trustees can split income across beneficiaries in lower tax brackets
- Distributions can be delayed until a minor turns 18, 21, or later
- Assets held in trust are harder for a beneficiary’s creditors or ex-partner to reach
A living trust (also called an inter vivos trust) is a different animal entirely. You set it up while alive, transferring assets into it now, usually for business succession, ongoing family control, or protecting property from future risk. A testamentary trust only ever exists in a will, and only after death.
Pro Tip: Don’t confuse the two when researching online. Most Australian articles about “family trusts” are talking about living trusts set up for business or tax reasons, not the testamentary trusts created inside a will.
Key differences at a glance
The clearest way to separate a simple will from a testamentary trust is timing and control. A will only ever activates on death and requires probate. A testamentary trust also activates on death, but instead of ending there, it keeps running for years under a trustee’s management.
- Timing: both take effect on death, but the trust structure continues operating afterwards
- Control: a will hands out lump sums; a trust lets a trustee manage and time distributions
- Probate and privacy: both usually go through probate and become part of the public court record, though a trust’s internal financial dealings stay private from that point
- Complexity and cost: a will is drafted once; a trust requires ongoing tax returns, trustee decisions, and accounting
Who suits a simple will and who should look at a trust
Your family structure and asset profile point fairly clearly toward one option over the other.
- Modest estate, adult beneficiaries, no complications — a simple will covers this comfortably. If your estate mainly consists of a home and some savings, and the beneficiaries can responsibly manage a lump sum, added trust structures add cost without adding value.
- Minor children involved — a testamentary trust lets a trustee hold funds until children reach a sensible age, rather than a court-appointed manager controlling the money until they turn 18. Guardianship planning matters just as much here as the trust structure itself.
- A vulnerable or special needs beneficiary — a trust can protect a beneficiary with special needs from losing government support entitlements that an outright inheritance might jeopardise.
- Blended family — trusts help balance a second spouse’s needs against children from a first relationship without one group’s inheritance swallowing the other’s.
- Business owner or high-net-worth estate — succession planning and creditor exposure both push toward a trust structure.
- Red flags worth acting on: a beneficiary going through divorce, a beneficiary with a pattern of poor money management, or a beneficiary carrying business or personal debt — all of these are signals a trust deserves a proper look.
What it costs to set up and run each option
Expect a simple will to sit at the lower end of legal drafting fees, while a testamentary trust costs more upfront because of the additional drafting and trustee provisions required. Treat any figure you see online as a starting point only. Get a fixed quote for your specific estate rather than relying on a rough industry number.
The bigger cost gap shows up after death. A simple will finishes its job once probate grants and assets transfer. A testamentary trust involves higher drafting and ongoing administration costs, including annual trust tax returns, trustee record keeping, and potential accounting fees for as long as the trust runs.
- Executors under a simple will have a finite, defined job
- Trustees under a testamentary trust take on a role that can last decades
- Complexity in the estate structure generally extends the administration timeline
Pro Tip: Ask any lawyer quoting you for a testamentary trust what the ongoing annual running cost looks like, not just the drafting fee. That number changes the maths considerably over ten or twenty years.
Tax and superannuation traps that change the calculation
Testamentary trusts offer real tax flexibility. Trustees can distribute income to beneficiaries in lower tax brackets, including minor children, who receive more favourable tax treatment on trust income than on other unearned income. That flexibility comes with compliance obligations, including annual trust tax returns, so factor an accountant’s fees into your comparison.
Capital gains tax can also apply differently depending on how and when assets move through an estate, so involve an accountant early if your estate includes property, shares, or a business.
Superannuation sits outside your will altogether in most cases. Death benefits are generally distributed by the fund trustee rather than under your will’s terms, unless you have a valid binding death benefit nomination in place. Plenty of Australians assume their super automatically follows their will. It does not, and that gap catches families out regularly.
A practical checklist before you speak to a lawyer
Work through these points before your consultation so the conversation moves straight to advice rather than fact-finding.
- Estate size and asset types — property, super, business interests, and investments all change the analysis.
- Family structure — blended family, minor children, or a beneficiary with a disability all point toward trust structures.
- Beneficiary risk factors — a pending divorce, debt exposure, or poor financial management history in a beneficiary’s life.
- Business or succession interests — business owners often need structures well beyond a simple will.
- Trustee availability — someone needs to be willing and capable of running a trust for years, not just months.
Bring these exact questions: What will drafting cost versus a testamentary trust cost, both now and annually? What trustee fees apply? How does this interact with my superannuation nominations? What’s the realistic timeline for probate and distribution? If your estate includes a business or overseas assets, ask whether you need combined legal and accounting advice from the outset.
Pro Tip: Write your questions down before the meeting. Estate planning conversations move fast, and it’s easy to forget the tax question once you’re deep into guardianship arrangements.
How Simons George Legal advises clients on this decision
Simons George Legal works with Sydney families across Bondi, the Eastern Suburbs, and regional NSW, and the firm’s wills and estates practice sees this exact decision play out weekly. Some clients arrive assuming they need a complex trust structure when their estate genuinely doesn’t warrant one. Others arrive with a simple will drafted years ago that no longer fits a blended family or a business they’ve since built.
A retired tradesperson with two adult children and a modest estate rarely needs a testamentary trust. A business owner with a second marriage, a school-age child, and commercial property almost always does. The right answer depends entirely on the family in front of us, not a template.
New clients receive a complimentary 30 minute consultation where Simons George Legal reviews the estate, the family structure, and any red flags before recommending a direction.
Changing your mind: amending a will versus a trust
A simple will is straightforward to amend. You can revoke it entirely and draft a new one, or add a formal codicil for minor changes, provided you have testamentary capacity and follow the proper execution formalities that apply in NSW, including witnessing requirements. Most people should redraft rather than patch with a codicil, since codicils create room for confusion about which version governs which clause.
A testamentary trust is different because it doesn’t exist yet. It’s a set of instructions inside your will, not a live structure, so amending it simply means amending the will itself before you die. Change the will, and you change the trust terms, the trustee appointments, and the distribution rules in one document.
Once you die, though, the position flips. A simple will’s terms become fixed and final the moment probate is granted, subject only to family provision claims. A testamentary trust, by contrast, keeps evolving after death because trustees exercise ongoing discretion over distributions for years. That flexibility is the whole point of choosing a trust in the first place, but it also means beneficiaries can’t simply demand a change the way you could while drafting your will.
If your circumstances shift significantly, such as a marriage, divorce, new child, or a business sale, review your will and any trust terms promptly. Waiting years between reviews is one of the most common causes of estates ending up governed by outdated instructions that no longer reflect the family’s real situation.
Common misconceptions about wills and trusts
The biggest misconception is that a testamentary trust operates like a living trust, protecting assets while you’re alive. It doesn’t. A testamentary trust only comes into existence on death, so anything you own before that point carries no trust protection at all.
A second common error is assuming super automatically follows the will. It doesn’t unless a valid binding nomination sits behind it, and outdated or invalid nominations leave super benefits at the discretion of the fund trustee.
Many people also assume a trust always beats a simple will. It doesn’t. Adding unnecessary trust structures increases expense and administrative burden without commensurate benefit for small, straightforward estates. A trust is a tool for a specific problem, not a universal upgrade.
There’s also a widespread belief that asset protection through a testamentary trust is automatic and total. It’s conditional. The degree of protection depends on trustee structure and the timing of asset transfers, and poorly drafted trust terms can leave gaps a family law court or creditor can exploit.
Finally, some assume a will and a trust are competing documents. They’re not. A testamentary trust lives inside the will. There’s no scenario where a valid trust provision overrides a will, because the trust is a clause the will creates, not a separate legal instrument sitting alongside it.
Real scenarios: which option actually fits
Scenario one: A couple in their sixties, one adult child, a paid-off home, and modest superannuation. Nothing about this estate calls for a trust. A simple will, correctly witnessed, with a straightforward executor appointment, does everything this family needs.
Scenario two: A single parent with two children aged nine and twelve. A simple will would see any court-appointed manager or the children themselves controlling significant funds the moment they turn 18. A testamentary trust lets a trustee release funds gradually, cover school fees and living costs as needed, and hand over full control only when the trustee judges the children ready, potentially well past 18.
Scenario three: A second marriage, two stepchildren, and a family home purchased before the remarriage. Without careful structuring, one side of the family can end up excluded or under provided for. A testamentary trust, paired with blended family estate planning, gives a trustee the discretion to balance both households fairly over time.
Scenario four: A tradesperson running a small business with three employees and $400,000 in commercial equipment. A simple will can name a beneficiary for the business, but it offers nothing on succession, creditor exposure, or keeping the business running through probate. A trust structure, combined with succession planning, protects the business itself rather than just its eventual sale value.
The pattern across every scenario is the same. Complexity in your family or your assets is what earns a trust its cost. Simplicity is what makes a simple will the right, cheaper answer.

George’s take: the trust obsession is overdone
Here’s what gets missed in most estate planning content: testamentary trusts get treated online as the sophisticated, superior choice, and simple wills get framed as the budget option for people who haven’t got their act together. That framing is backwards for a huge slice of Australian families.
A trust is a tool built to solve specific problems: minors, vulnerable beneficiaries, blended families, creditor exposure, business succession. If none of those problems exist in your situation, a trust adds a trustee’s ongoing workload, annual tax returns, and years of administrative overhead for no real gain. I’ve seen plenty of straightforward advice pushed aside because a trust sounded more thorough, when a well-drafted simple will would have achieved the identical outcome for a fraction of the cost and complexity.
The flip side is just as real. Families who genuinely need trust protection, particularly those with a beneficiary at risk from a relationship breakdown or a creditor, sometimes skip it purely to save on drafting fees, then watch that decision cost far more later when an inheritance gets absorbed into someone else’s divorce settlement. The right call isn’t about which option sounds more sophisticated. It’s about matching the structure to the actual risk sitting in front of you, which is exactly why this decision deserves a proper conversation rather than a guess.

FAQ
Is it better to have a will or a trust in Australia?
Neither is universally better. A simple will suits modest, uncomplicated estates, while a testamentary trust suits estates with minors, vulnerable beneficiaries, or creditor and relationship risk.
Does a will override a family trust?
A will doesn’t override a testamentary trust because the trust exists inside the will itself, created by its terms rather than sitting as a separate competing document.
Is the ATO cracking down on family trusts?
The ATO has increased scrutiny of trust income distribution arrangements generally, which is one reason testamentary trusts need proper accounting and tax compliance built into their ongoing administration.
What happens to superannuation if I only have a will?
Superannuation death benefits are generally distributed by the fund trustee and can bypass your will entirely unless you have a valid binding death benefit nomination in place.
Can I change my mind after setting up a testamentary trust?
You can amend the trust terms freely by updating your will while alive, but once the trust activates on death, its terms and trustee discretion take over from that point.
