This is one of the most common estate planning questions we’re asked.
Oftentimes our clients are concerned about protecting their children’s inheritance, or trying to work out whether a standard Will is enough.
The short answer is: it depends on your assets and your family structure.
A testamentary trust is a trust created under your Will. It only comes into effect after your death. Instead of leaving assets directly to a beneficiary, the assets are held in a trust and managed by a trustee for their benefit.
They are not just for the wealthy. In many cases, they are appropriate for ordinary families who own a home, have children, or hold investment assets.
When a Testamentary Trust Makes Sense
Young children
If you have minor children, a testamentary trust allows assets to be held and applied for their benefit without handing everything over at 18. You decide the structure in advance.
There is also a significant tax advantage. Income distributed from a testamentary trust to minors is generally taxed at ordinary adult marginal rates, not the penalty rates that usually apply to children.
Blended families
Second marriages often require careful structuring. A testamentary trust can allow a surviving spouse to receive income and use of assets during their lifetime, while preserving capital for children from a previous relationship. Without that structure, estates can quickly become the subject of litigation in the Supreme Court of New South Wales.
Asset protection
If your beneficiaries are in business, exposed to personal liability, or at risk of relationship breakdown, leaving assets to them outright can create unnecessary exposure. A properly drafted testamentary trust can provide a layer of protection against creditors and family law claims, depending on the circumstances.
Business and investment assets
If you hold investment properties, shares, or business interests, a testamentary trust allows income to be streamed flexibly within the family group. Over time, that flexibility can produce material tax efficiencies.
This is why many clients looking into asset protection wills or searching for testamentary trust advantages ultimately decide that a basic Will is not enough.
When It May Not Be Necessary
Not every estate requires a trust structure.
If you are leaving everything to a financially responsible spouse, there are no minor children, and there are no asset protection concerns, a simpler Will may be appropriate.
A testamentary trust does involve ongoing administration. There are annual tax returns, trustee duties and accounting requirements. The structure needs to be proportionate to the size and complexity of the estate.
The Real Issue
The question is not whether testamentary trusts are “good”. The question is whether they are appropriate for you.
If you own property in NSW, have children from more than one relationship, operate a business, or are concerned about protecting inheritances from divorce, a testamentary trust is often worth serious consideration.
If your affairs are straightforward, a simpler structure may achieve the same objective without unnecessary complexity.
