A discretionary trust in a will can give your family valuable protection when a simple gift to a beneficiary may not be the right answer. It can be particularly useful where children are young, a loved one is vulnerable, or you are concerned that an inheritance could be spent too quickly or put at risk during a relationship breakdown.
But this type of trust is not a one-size-fits-all solution. It gives trustees considerable responsibility, can create ongoing administration, and may not suit an estate that is straightforward. The right choice depends on who you want to protect, what assets you are leaving and how much flexibility your family may need after you die.
What is a discretionary trust in a will?
A discretionary trust is a trust created by your will that starts after your death. Rather than leaving money or property directly to one person, you place it into a trust for a group of possible beneficiaries.
The people you appoint as trustees decide how, when and whether the trust fund should be used for those beneficiaries. They might pay a beneficiary a regular amount, meet school or university costs, contribute towards a house deposit, or hold the money until circumstances are more settled.
For example, you could leave your estate to a discretionary trust for your children and grandchildren. Your trustees could then use funds for a child’s education while they are young, help another beneficiary through a difficult period, and retain the remaining money for the future.
The key point is that no individual beneficiary has an automatic right to a fixed share of the trust. The trustees must use their discretion within the terms you set out in the will.
Why choose a discretionary trust in a will?
Life rarely stays as predictable as we expect. A discretionary trust allows you to plan for uncertainty without trying to predict every future need in your will.
It is often considered where parents want to provide for children who are still young. Leaving money to a child outright at 18 may be legally simple, but it may not reflect what you would want in practice. A trust can allow trustees to use funds for the child’s benefit while delaying a full inheritance until a later age, if appropriate.
It can also help where a beneficiary is financially inexperienced, vulnerable to pressure from others, dealing with addiction, or likely to receive means-tested benefits. Since the beneficiary does not own a fixed entitlement to the trust fund, a discretionary trust may offer more protection than a direct gift. However, benefit rules are complicated and depend on the person’s circumstances, so specialist advice is sensible where this is a concern.
For blended families, flexibility can matter too. You may want trustees to be able to provide for a surviving partner, children from a previous relationship and future grandchildren, without fixing exact amounts before you know what each person will need.
Trustees hold real responsibility
The trustees are central to whether the arrangement works. They legally own and manage the trust assets, but they must use them for the benefit of the people named in the trust.
You can appoint family members, friends, professionals, or a mixture of both. Many people choose two or more trustees so that decisions are not left to one person alone. Your executors and trustees can be the same people, but their roles are different. Executors deal with administering your estate after death. Trustees manage the assets held in the trust, often over a much longer period.
Trustees need to act carefully and fairly. They must consider the beneficiaries’ circumstances, keep suitable records, invest money appropriately and deal with any tax and reporting obligations. Choosing someone because they are close to the family is not enough. They also need to be reliable, organised and able to make difficult decisions.
A professional trustee may bring experience and independence, especially where family relationships are strained. The trade-off is cost. Professional fees can be worthwhile in a complex estate, but they may be disproportionate for a modest trust fund.
A letter of wishes can guide trustees
A will can give trustees powers, but it does not need to dictate every possible decision. Many people prepare a separate letter of wishes to explain how they hope the trust will be used.
You could say that education should be prioritised, that a beneficiary should not receive a large cash payment while they are young, or that trustees should consider help with housing. This letter is not usually legally binding, which means it can be updated during your lifetime without changing the will. It gives trustees helpful context while preserving the flexibility that makes a discretionary trust useful.
What assets can go into the trust?
A discretionary trust can receive all or part of your estate. It is commonly created through a residuary gift, meaning the trust receives what remains after debts, funeral expenses, tax and specific gifts have been dealt with.
It can also receive a particular sum of money or a specified asset. Care is needed with property. If your home is left into a trust, the practical and tax implications can be significant, particularly if a spouse, civil partner or co-owner needs somewhere to live.
A discretionary trust is not always the best way to protect a home for a surviving spouse or partner while preserving its value for children. In some cases, a life interest trust may fit that aim more closely, allowing a person to live in the property or receive its income while protecting the capital for those who inherit later.
How you own the property also matters. A jointly owned home may pass automatically to the surviving owner if it is owned as joint tenants, regardless of what your will says. This is why will planning and property ownership should be considered together.
The drawbacks to understand before you decide
Flexibility comes with complexity. A discretionary trust is not simply a gift with a different label.
The trust may need a bank account, records, accounts, tax returns and decisions documented by trustees. Income received by the trust can be taxed differently from income received directly by an individual. Depending on its value and circumstances, there may also be inheritance tax charges during the life of the trust, including potential ten-year and exit charges.
The administration can also delay beneficiaries receiving funds. That may be entirely appropriate where protection is needed, but less so where an adult beneficiary simply needs a modest inheritance promptly to clear a mortgage or manage everyday costs.
There is a human consideration too. Trustees are asked to make decisions that may disappoint someone. If one child receives support for a business or deposit while another does not, tensions can arise even when the trustees are acting properly. Clear trustee choices and a well-considered letter of wishes can reduce the risk of misunderstanding, but they cannot remove it completely.
A discretionary trust does not guarantee protection from every claim, debt, divorce settlement or care-cost assessment either. The facts of each case and the way the trust is operated matter. It should never be treated as a way to hide assets or avoid legitimate obligations.
When might a simpler will be better?
For many households, a clear will leaving assets directly to a spouse, civil partner, children or other chosen beneficiaries is the most practical option. It is easier to understand, less expensive to administer and gives beneficiaries certainty.
A straightforward will may be suitable where beneficiaries are responsible adults, family circumstances are settled and there is no particular reason to control how an inheritance is used. You can still choose trusted executors, name guardians for children and make specific gifts without creating a long-running trust.
On the other hand, if you have young children, a vulnerable beneficiary, a complicated family arrangement, a business interest or substantial assets, a trust may be worth discussing. The more a trust needs to achieve, the more important it is that the wording is tailored properly. Generic provisions can cause difficulties if they do not match your family’s needs.
Questions to ask before including one
Before putting a discretionary trust in your will, think honestly about the practical outcome you want. Who could benefit from the trust, and why should trustees have discretion rather than a fixed instruction? Which assets should go into it? At what stage, if any, should beneficiaries receive money outright?
You should also consider who could act as trustees for years to come, whether they would work well together and whether the trust fund is large enough to justify the cost of ongoing administration. If you are trying to protect a particular person or property, ask whether a different type of trust may meet that aim more directly.
Making a will is about giving your family clarity at a difficult time. A discretionary trust can be a thoughtful safeguard where flexibility is genuinely needed, but the best plan is the one your trustees can manage and your loved ones can understand. Put your wishes in writing now, while you can make those choices calmly and clearly.
