The Benefits of Testamentary Trust Wills Explained

September 9, 2025

Testamentary Trust Wills provide significant benefits for individuals and families planning the distribution of their estates in Western Australia, particularly in terms of asset protection, tax efficiency, and supporting vulnerable beneficiaries. These trusts are established within a Will and become effective upon death, offering tailored advantages for diverse family circumstances.


Key Benefits of Testamentary Trust Wills


Asset Protection


  • Safeguards inheritance from creditors, bankruptcy, and family law disputes by holding assets within a trust rather than direct ownership by beneficiaries.


  • Shields assets from potential misuse or waste by beneficiaries with high-risk behaviours such as gambling, financial instability, or poor money management.


  • Protects funds from being included in divorce settlements, ensuring they remain accessible only to intended family members.


Tax Advantages


  • Optimises tax outcomes by enabling income splitting among beneficiaries, especially those on lower marginal tax rates.


  • Allows income distributed to minor children (under 18) via a testamentary trust to receive the full adult tax-free threshold (around $19,000–$22,000 per child annually, tax-free), compared to only about $500 in a standard family trust.


  • Provides flexibility to defer tax liabilities for overseas beneficiaries by controlling the timing and distribution of income.


Support for Vulnerable and Young Beneficiaries


  • Helps ensure responsible use of inherited assets by enabling trustees to set age thresholds (e.g., 21, 25, or older) for the release of funds to younger beneficiaries.


  • Allows creation of specialised trusts for beneficiaries living with disabilities, including Social Security Act 1991 (Cth) compliant Special Disability Trusts.


  • Can provide long-term security for those who require ongoing support, such as family members with health challenges or special needs.


Estate Planning Flexibility


  • Highly customisable trusts can be tailored for one person, an entire family, or multiple generations, addressing complex family or blended family situations.


  • Enables control over how and when assets are distributed, including restricting access to certain beneficiaries or protecting inheritance lines within families.


  • Trustees are chosen to ensure accountability, oversight, and alignment with the intentions of the Will-maker, often with recommendations for two trustees to reduce risks.


Who Should Consider a Testamentary Trust Will?


  • Individuals leaving substantial estates (often $2,000,000 or more) including superannuation or life insurance.


  • Estates intended to support minor children, vulnerable adults, or those likely to face relationship or financial risks.


  • Families wishing to maximise tax savings and asset protection across generations.

A new year is the perfect time to revisit an important question: is your Will still up to date? Many people make a Will once and then leave it untouched for years. But life rarely stays still. Relationships change, children are born, assets are bought and sold, businesses evolve, and family circumstances shift. A Will that once reflected your wishes may no longer do so. For that reason, reviewing your Will regularly is one of the simplest ways to protect the people and assets that matter most. Why people delay updating their Will It is easy to put off Estate Planning. Some people assume their Will is “good enough” because nothing dramatic has happened. Others feel uncomfortable thinking about what happens after they are gone. In practice, the most common reason Wills become outdated is not neglect in a dramatic sense, but everyday change. You may have: Married or separated. Had children or grandchildren. Bought property. Started or sold a business. Gained or lost significant assets. Named an Executor who is no longer suitable or available. If any of these apply, your current Will may need review. What can happen if a Will is outdated An outdated Will can create confusion, delay, and conflict at exactly the moment your family is already dealing with loss. It may also fail to reflect your real intentions. For example, assets may pass to someone you no longer intended to benefit, or a chosen Executor may no longer be the right person to manage the Estate. In some cases, the wording of an old Will can even create disputes that could have been avoided with a simple update. When to review your Will A good rule of thumb is to review your Will after any major life event, and otherwise every few years. You should consider an update if you have experienced: A marriage, divorce, or de facto relationship change. The birth or adoption of children. A death in the family. A major change in assets or liabilities. A move interstate or overseas. A change in your wishes about guardianship for your children, gifts, or Executors. Even if nothing major has changed, a periodic review helps ensure your instructions remain clear and legally effective. A simple process can prevent future problems Updating a Will does not have to be complicated. In many cases, a short review with a lawyer is enough to confirm whether the existing document still works or whether a new will is needed. A proper review can also identify related issues, including: Powers of attorney. Appointment of guardians. Superannuation nominations. Business succession arrangements. Asset ownership structures. These matters often work together, so an estate plan should be considered as a whole rather than as a single document. The takeaway The start of a new year is a useful reminder to get organised, and your Will should be part of that process. If your circumstances have changed, or if it has been several years since your last review, now is a sensible time to take another look. A current, well-drafted Will can save your family stress later and help ensure your wishes are carried out clearly.

At Crabtree Legal, we understand that protecting your children’s inheritance from potential relationship breakdowns is a crucial concern for many families. The landmark Family Court of Australia decision in Bernard and Bernard [2019] FamCA 421 confirmed that testamentary trust Wills can be an effective tool in safeguarding a beneficiary’s inheritance from being divided upon divorce. Background of the Case In Bernard v Bernard, the husband’s late father created two discretionary testamentary trusts through his Will — one for his son and one for his daughter. The trusts operated as “mirror trusts”: each sibling was the trustee of the other’s trust but had no control over their own trust. The husband was the primary beneficiary of his trust, but the assets were legally owned and controlled by his sister as trustee. When the husband and wife later separated and divorced, the wife sought to have the husband’s inheritance held in the testamentary trust included in the matrimonial property pool for division. However, the husband argued that since he did not legally own or control the trust assets, and his interest was solely as a beneficiary dependent on the trustee’s discretion, the inheritance should be excluded from the property pool. Court’s Decision and Key Findings The Family Court ruled in favor of the husband, finding that the assets in the testamentary trust were not part of the matrimonial pool. The court’s key reasoning was that: The husband was not the settlor of the trust—the deceased father was. The husband had no legal ownership or control over the trust assets. The trustee (the husband’s sister) had complete discretion over income and capital distributions. The husband’s interest was discretionary and not guaranteed, meaning he could not compel distributions. The trust assets were inherited and not acquired during the marriage. This decision confirmed that a properly structured testamentary trust can protect a beneficiary’s inheritance from being divided upon divorce by separating legal ownership and control from mere beneficial interest. Why This Matters for Your Estate Planning Bernard v Bernard highlights how testamentary trust Wills can be used to safeguard your children’s inheritance from future relationship breakdowns, ensuring that inherited assets remain protected within the family and are not treated as divisible property in the event of a divorce.
