Key Takeaways
- Post-budget testamentary trust disputes in Victoria arise where wills signed after 12 May 2026 create discretionary testamentary trusts that may be subject to the proposed 30% minimum trust tax from 1 July 2028, prompting disputes about retaining, varying, winding up, or assessing the trust’s after-tax value.
- The legal framework is an intersection of Victorian succession law (Wills Act 1997 (Vic) — notably s31 rectification — and Administration and Probate Act 1958 (Vic) for family provision claims) and federal tax law (anticipated amendments to the Income Tax Assessment Act 1997 (Cth)).
- Victorian courts start with the will-maker’s intent and the will’s terms; rectification is only available where the signed will fails to reflect actual instructions (e.g. drafting errors), and courts will not rewrite a will merely because the trust is now tax‑disadvantaged.
- Typical disputes include executor vs beneficiary fights over retaining or winding up trusts, rectification claims where a will was drafted before but signed after 12 May 2026 without updated advice, and family provision claims where trustee-level tax may reduce distributions.
- Practical steps: preserve contemporaneous evidence (solicitor file notes, draft wills, tax advice), obtain early legal and tax advice before executors make irreversible decisions, and consider timely s31 rectification applications (usually within six months of probate) alongside family provision strategy.
What are post-budget testamentary trust disputes in Victoria?
Post-budget testamentary trust disputes Victoria matters may arise where a will signed after 12 May 2026 creates a discretionary testamentary trust affected by the proposed 30% minimum trust tax from 1 July 2028. Executors and beneficiaries may dispute whether the trust should be retained, varied, rectified or considered differently in a family provision claim once its after-tax value is assessed.
A Victorian business owner, investor or high-net-worth parent who signs a will after 12 May 2026 may leave their executors with a tax problem that becomes an estate dispute. Under the Federal Budget 2026-27 measure, discretionary testamentary trusts created by post-budget wills are expected to fall within the 30 per cent minimum trust tax from 1 July 2028, while wills signed before budget night are expected to be protected from the new regime.
For executors and beneficiaries in Victoria, the issue is no longer only whether a testamentary trust gives flexibility, asset protection, or control. It is whether the trust structure still serves the estate once its after-tax value is tested. That shift is likely to drive post-budget testamentary trust disputes in Victoria, including executor discretion, post-budget will dispute arguments, family provision claims and rectification applications where the will-maker’s instructions failed to account for the new regime.
The practical questions are immediate: whether the executor should retain or wind up the testamentary trust, whether beneficiaries can seek rectification where a post-budget will failed to account for the new tax setting, and whether any family provision claim should be assessed by reference to the trust’s after-tax value.
What law applies to post-budget testamentary trust disputes in Victoria?
In Victoria, post-budget testamentary trust disputes sit at the intersection of succession law, estate administration, and federal tax law. The core Victorian statutes are the Wills Act 1997 (Vic) and the Administration and Probate Act 1958 (Vic). The tax setting is expected to be implemented through amendments to the Income Tax Assessment Act 1997 (Cth) and related federal tax legislation.
Section 31 of the Wills Act 1997 (Vic) is central where a will signed after 12 May 2026 creates a discretionary testamentary trust that the will-maker did not intend to expose to the new 30 per cent minimum trust tax. If the signed will does not reflect the will-maker’s actual instructions or intentions, section 31 allows the Supreme Court of Victoria to correct the document in limited circumstances, including where the problem arose from a drafting or clerical error. An application is required within six months from the grant of probate, although the Court may extend time in appropriate cases.
The recent Victorian decision in Re Estate of Moore [2025] VSC 527 is useful because it confirms the discipline required in rectification cases. The Court’s role is not to improve a commercially inconvenient estate plan after the event. The question is whether the signed document failed to give legal effect to the will-maker’s actual instructions or intentions.
The Administration and Probate Act 1958 (Vic) also matters because Part IV governs family provision claims. In a post-budget will dispute, the real value of a testamentary trust may be contested if trustee-level tax reduces income or changes the benefit available to a spouse, child, or dependant.
Construction and trust administration principles will also matter. In Re AM McClelland Estate [2025] VSC 343, the Court considered how a long-running testamentary charitable trust could be administered where its original terms no longer operated effectively. Although charitable trust cases differ from private discretionary testamentary trusts, the broader point is relevant: Victorian courts examine the will, trust purpose, and trustee powers before deciding whether a trust structure should continue, be varied or be administered differently.
For high-value Victorian estates, the legal question is not simply whether the will is valid. It is whether the testamentary trust still performs the role the will-maker intended once post-budget tax consequences are considered.
How do Victorian courts approach testamentary trust disputes after a tax change?
What question will the court ask first?
In a Victorian post-budget testamentary trust dispute, the Court starts with the will and the powers it gives to the executor or trustee. The first question is not whether the trust is now tax-effective, but what the will-maker intended the will to do. If the will clearly directs the creation of a discretionary testamentary trust, the Court will treat that instruction as legally significant. A later tax disadvantage does not, by itself, permit beneficiaries to replace the will-maker’s chosen structure with a different arrangement.
That matters for wills signed after 12 May 2026. If the will-maker chose a testamentary trust after the budget announcement, the dispute will usually turn on the will’s terms, the trustee’s powers, the advice given and whether the signed document reflects the will-maker’s instructions.
What evidence do courts require?
Evidence is central. In a claim for rectification of a testamentary trust in Victoria, the Court looks for material showing the will-maker’s actual instructions and whether the signed will failed to give legal effect to them. Relevant evidence may include solicitor file notes, draft wills, letters of advice, emails, tax advice, estate planning memoranda, and records of conferences with the will-maker.
Timing also matters. A will signed before budget night, a will already in draft on 12 May 2026, and a will signed shortly after the announcement may each raise different evidentiary issues. If a will was drafted before the budget but signed afterwards without revisiting the tax position, the question may be whether the executed will reflects the instructions the will-maker gave and understood.
When does executor discretion become the issue?
Executor and trustee discretion becomes important where the will gives powers to allocate assets, postpone distribution, appropriate assets between beneficiaries or hold property on testamentary trust. In a post-budget will dispute, the question is whether those powers permit the executor to retain the trust, distribute assets outright, or administer the estate in another way consistent with the will.
The executor’s duty is not simply to produce the lowest tax outcome. The executor must administer the estate according to the will, act for proper purposes, consider the interests of beneficiaries and avoid conflicts. For high-value estates, that may require tax advice and estate litigation advice before a decision is made.
When will a court refuse relief?
A Court will be cautious where the will is clear and the evidence does not show a recognised legal basis for intervention. Relief is more likely where there is evidence of a drafting error, a failure to give effect to instructions, or an executor decision made outside the will’s powers. It is less likely where the testamentary trust was deliberately chosen and the complaint is only that the structure has become less attractive after the Federal Budget 2026-27 measure.
What disputes arise when a post-budget will creates a taxed testamentary trust?
The most immediate dispute is often between executors and beneficiaries over whether the testamentary trust should be retained. In high-value Victorian estates, the trust may hold business interests, investment properties, private company shares, or substantial managed investments. If the will gives the executor power to distribute assets outright, one group of beneficiaries may argue that the trust should be wound up or bypassed to avoid the 30 per cent minimum trust tax. Another may argue that the trust should remain because it still provides asset protection, succession control, or protection for vulnerable beneficiaries.
A second dispute arises where the will was in draft before 12 May 2026 but signed after budget night. The will-maker may have approved a testamentary trust structure before the budget measure was announced, then signed the final document days or weeks later without fresh advice on the new tax setting. In that situation, an intended beneficiary may consider a Victorian testamentary trust rectification claim if the signed will does not reflect the instructions the will-maker gave and understood.
A third dispute concerns family provision. The after-tax value of a testamentary trust may affect whether adequate provision has been made for a spouse, adult child, dependant or blended family beneficiary. A claimant may argue that their entitlement is materially reduced if distributions are exposed to trustee-level tax. An executor or opposing beneficiary may respond that the trust still gives meaningful long-term benefits, particularly where asset protection or controlled succession was part of the estate plan.
These disputes often overlap with family trusts and estate disputes, especially where control of business assets, investment entities or intergenerational wealth structures is contested. They may also intersect with the mutual wills doctrine in Victoria where spouses or partners made coordinated wills, and one party later changed the estate plan.
Practical issues also arise for wills signed before budget night. Those wills may be protected from the new regime, but protection can be put at risk if the will is later revoked, replaced, or materially changed. In substantial estates, the dispute is rarely about tax. It is usually about control, timing, commercial value and who bears the cost of an estate plan that no longer operates as expected after the Federal Budget 2026-27 measure.
What evidence matters before pursuing or defending a post-budget will dispute?
Before pursuing or defending a post-budget will dispute, the first strategic issue is evidence. A claim for rectifying a testamentary trust will in Victoria will usually depend on contemporaneous records, not later dissatisfaction with the tax outcome. The key documents are the solicitor’s file, draft wills, written instructions, tax advice, estate planning memoranda, file notes, emails, and any letters of wishes. Those records may show whether the will-maker understood the effect of signing a will after 12 May 2026, or whether the final document failed to reflect the instructions given.
Concerned a post-budget will has created a tax-exposed trust?
Testamentary trust disputes can quickly become disputes about executor powers, rectification, family provision, after-tax value and whether the will still reflects the will-maker’s intentions. If a post-budget will or draft will may be affected by the proposed 30% minimum trust tax, early advice can help protect the estate, beneficiaries and executor decision-making.
Book a Consultation Pentana Stanton Lawyers advises executors, beneficiaries and high-value estate clients in complex wills disputes, trust disputes and contested estate matters across Victoria.Timing should be assessed early. If probate has been granted, any section 31 rectification issue under the Wills Act 1997 (Vic) should be considered promptly because delay can affect both procedure and evidence. Where a family provision claim is also being considered under the Administration and Probate Act 1958 (Vic), the litigation strategy should deal with both the legal structure of the trust and the real after-tax value available to the claimant.
Executors should avoid making irreversible decisions about retaining, winding up, or distributing from a caught testamentary trust before obtaining advice. A decision made for the wrong purpose, without considering relevant tax and beneficiary issues, may itself become the dispute. Equally, beneficiaries should not assume that the 30 per cent tax on testamentary trusts in Victoria automatically justifies setting aside or bypassing the trust.
The strongest strategy in these matters is usually forensic and commercial. Identify the will-maker’s instructions, test the executor’s powers, obtain tax modelling where needed, and decide whether the dispute is properly about rectification, construction, executor discretion, or family provision. That early classification can determine whether the matter resolves by advice, negotiation, or court application.
Frequently Asked Questions
Which wills are caught by the new 30 per cent tax on testamentary trusts in Victoria?
The announced measure is expected to apply to discretionary testamentary trusts created by wills signed after 12 May 2026. The tax is expected to apply from 1 July 2028, not when the will is signed. In Victoria, this may become a dispute issue where beneficiaries say a post-budget will created a tax-exposed trust the will-maker did not properly understand or intend.
What happens to wills signed before 12 May 2026?
Wills signed before 12 May 2026 are expected to be protected from the new 30 per cent minimum trust tax. That protection may be important where an existing will already creates a discretionary testamentary trust. Caution is needed if the will is later revoked, replaced, or materially changed, because a new post-budget will may fall within the regime.
Can an executor wind up a testamentary trust affected by the new tax?
An executor can only wind up or bypass a testamentary trust if the will and the law allow it. The executor must identify the powers given to them and act for proper purposes. A beneficiary cannot force an executor to abandon the trust merely because the tax result is unattractive. In a post-budget will dispute, the decision should usually be supported by legal and tax advice.
How do you update a will to avoid the new testamentary trust tax?
A will should be reviewed before it is signed, especially if it contains a discretionary testamentary trust. The update may involve removing the trust, changing the trust structure, giving the executor clearer distribution powers or using a different estate planning strategy. The right approach depends on the estate assets, beneficiaries, tax position, and asset protection objectives.
Is there a deadline to update a will after the Federal Budget 2026-27?
There is no single deadline for every estate plan, but timing matters. The key date is 12 May 2026 because wills signed after that date are expected to be treated differently from before budget night. The tax is expected to apply from 1 July 2028, which creates a review window but not a reason to delay. Anyone with a will in draft or a recent post-budget will should obtain advice promptly.
What should you do if a post-budget will creates a tax-exposed testamentary trust?
A post-budget will that creates a discretionary testamentary trust should be reviewed before executor decisions become entrenched or beneficiaries take fixed positions. The key issues are whether the will-maker intended the trust to operate in its current form, whether the executor has power to retain or wind up the structure, and whether the after-tax value of the trust affects any family provision claim.
