Discretionary Trust Singapore: When You Let the Trustee Decide Who Gets What
The trust structure built for flexibility rather than fixed, predetermined shares

A discretionary trust is a trust structure in which the trustee is given the power to decide, within a class of potential beneficiaries and according to the terms of the trust deed, how much each beneficiary receives and when, rather than each beneficiary having a fixed, predetermined entitlement — making it a popular choice in Singapore for families who want ongoing flexibility as circumstances change over time.
Key Takeaways
- In a discretionary trust, no individual beneficiary has an automatic, fixed right to any specific asset or amount — the trustee decides, guided by the trust deed and often a separate, non-binding letter of wishes.
- This structure is commonly used in Singapore for families with beneficiaries of different ages, needs, or financial responsibility levels, since it lets the trustee adapt distributions over time.
- Because beneficiaries hold no fixed entitlement until the trustee actually exercises discretion in their favour, discretionary trust assets can offer a layer of protection against certain creditor or divorce claims against a beneficiary.
- A settlor typically provides a non-binding letter of wishes alongside the trust deed to guide the trustee’s exercise of discretion, without legally restricting it.
- Discretionary trusts require a trustworthy, competent trustee, since so much depends on how fairly and prudently that trustee exercises their discretion over the years.

What Is a Discretionary Trust?
A discretionary trust is one of the two broad categories of trust structure (the other being a fixed trust), distinguished by how much control the trustee has over distributions. Under a discretionary trust, the trust deed names a class of potential beneficiaries — for example, “the settlor’s children and grandchildren” — but does not specify exactly how much each individual will receive or when. Instead, the trustee is given genuine discretion to decide, from time to time, which beneficiaries within that class receive income or capital from the trust, and in what amounts.
This is a deliberate design choice, not a loophole: it allows the trust to adapt to circumstances that cannot be fully predicted at the time the trust is set up, such as one beneficiary developing special needs, another going through financial difficulty, or the birth of new grandchildren years after the trust was created. Because no beneficiary has a fixed, enforceable right to a specific share until the trustee actually exercises discretion in their favour, a discretionary trust also offers a different — generally stronger — layer of asset protection compared to a fixed trust, since a beneficiary’s creditors or a divorcing spouse generally cannot claim against an interest that does not yet legally exist in fixed form.
How Does a Discretionary Trust Work in Singapore?
In Singapore, discretionary trusts are commonly used in family wealth and business succession planning, often set up with a licensed trust company as the professional trustee, particularly for larger or more complex family estates, or in conjunction with a family office structure. The trust deed sets out the class of beneficiaries and the trustee’s powers, while the settlor typically also prepares a separate, non-legally-binding letter of wishes, giving the trustee guidance on how the settlor would like discretion to be exercised — for example, prioritising education expenses for younger beneficiaries, or being cautious about large capital distributions to a beneficiary known to have spending difficulties.
Because the letter of wishes is not legally binding, the trustee retains the final say, which is precisely the point of the structure, but it also means the choice of trustee matters enormously: a trustee who deviates significantly and unreasonably from a settlor’s clearly expressed wishes without good cause can potentially face legal challenge from beneficiaries, even though the trust deed grants formal discretion. Singapore-based discretionary trusts administered by MAS-licensed trust companies benefit from professional oversight and Singapore’s well-regarded, English-common-law-based trust jurisprudence, which is one reason the country has become a popular regional base for family trust structures.
a Discretionary Trust Example
Mr Ho sets up a discretionary trust naming his three children and any future grandchildren as the class of beneficiaries, appointing a licensed trust company as trustee, and provides a letter of wishes indicating he would like the trust to prioritise funding education and only make larger capital distributions once a beneficiary turns 30 and demonstrates financial responsibility. Ten years later, his youngest daughter faces unexpected medical expenses, while his eldest son, now financially independent and running his own business, needs no support at all that year.
Because the trust is discretionary, the trustee can direct a larger distribution to the daughter to cover her medical costs that year, while making no distribution at all to the son — a flexible response that a fixed trust, which would have locked in equal or predetermined shares for each child regardless of their actual circumstances at the time, could not have accommodated.
Advantages of a Discretionary Trust
Adapts to changing family circumstances. The trustee can respond to real, evolving needs — illness, financial hardship, new grandchildren — that could not have been fully anticipated when the trust was first set up.
Stronger asset protection potential. Because no beneficiary holds a fixed entitlement until discretion is actually exercised in their favour, discretionary trust assets can be harder for a beneficiary’s creditors or a divorcing spouse to claim against, compared to a fixed trust interest.
Useful for beneficiaries who are not yet identified or ready. A discretionary trust can name a broad class (such as “future grandchildren”) without needing to know exactly who or how many there will eventually be.
Can manage tax and succession planning flexibly. Trustees can time distributions to align with beneficiaries’ individual circumstances, which can be useful for coordinating with each beneficiary’s own tax and financial planning needs, within the bounds of the trust deed and applicable law.
Risks and Limitations
Beneficiaries have no guaranteed entitlement. Because nothing is fixed, a beneficiary the settlor intended to benefit could, in principle, receive little or nothing if the trustee exercises discretion differently than expected — making the choice and ongoing conduct of the trustee critical.
Heavily dependent on trustee quality and integrity. A poorly chosen, negligent, or self-interested trustee can cause real harm precisely because they hold so much discretionary power, which is why selecting a reputable, MAS-licensed trust company or experienced professional trustee matters so much.
Letters of wishes are not legally binding. While helpful as guidance, a letter of wishes cannot force a trustee’s hand, so a settlor’s intentions could, in theory, be departed from, even if this would typically need to be for a legitimate reason given fiduciary duties.
Can create uncertainty and family tension. Beneficiaries who do not know what, if anything, they will receive, and when, may find this uncertainty stressful, and unequal distributions over time can sometimes cause friction between siblings or relatives.
Higher setup and ongoing administration complexity. Professional trustee fees, more detailed drafting, and ongoing trustee decision-making (including proper record-keeping of how and why discretion was exercised) generally make discretionary trusts costlier to run than simpler fixed structures.
Discretionary Trust vs Fixed Trust
| Feature | Discretionary Trust | Fixed Trust |
|---|---|---|
| Beneficiary entitlement | No fixed share — trustee decides amount and timing | Predetermined, specific share for each beneficiary |
| Flexibility to adapt | High — can respond to changing circumstances | Low — terms are fixed in the trust deed |
| Asset protection potential | Generally stronger, since no fixed interest exists yet | Weaker — a fixed interest can be a clearer target for claims |
| Dependence on trustee judgment | High | Low — trustee mainly administers, doesn’t decide shares |
| Typical use case | Families with evolving needs, business succession | Simple, predictable distributions (e.g. to minors at a set age) |

The Bottom Line
A discretionary trust trades certainty for flexibility, giving families a structure that can genuinely adapt to real life as it unfolds over decades, but that flexibility only works well when paired with a carefully chosen, trustworthy trustee and a clear (even if non-binding) letter of wishes — without those two things, the very discretion that makes this structure powerful can also become its biggest weakness.
