Trusts for Children: Why Structure and Entitlement Matter

Start With Structure, Not Just Age

In England and Wales, trusts for children are often discussed as though the main issue is simply whether a child should inherit at 18, 21 or 25. That can be an understandable way to start the conversation, but it is not the whole answer. The more useful question is what kind of trust is being created and what rights the child will actually have under it. An age reference may still matter, but it does not by itself explain whether the child has a fixed entitlement, whether trustees can decide what is paid out, or whether income and capital are treated differently.

The GOV.UK guidance on types of trust shows why this matters. It lists bare trusts, interest in possession trusts, discretionary trusts, accumulation trusts and mixed trusts, and explains that each type is taxed differently. More importantly for practical will planning, each type can operate in a different way for beneficiaries and trustees. When families are thinking about Wills with Trusts, the real planning issue is usually not just how old a child should be, but whether the trust is meant to give certainty, flexibility, staged benefit or a mixture of those aims.

Why an Age Clause Does Not Always Prevent Access

A common assumption is that putting a later age into a will will always stop a child from accessing funds until that age. The GOV.UK material does not support that as a universal rule. It says that in a bare trust, the beneficiary has the right to all of the capital and income of the trust at any time if they are 18 or over in England and Wales. It also says bare trusts are often used to pass assets to young people, with trustees looking after the assets until the beneficiary is old enough.

That point is central to the way entitlement works. If an arrangement is a bare trust, the beneficiary’s right at 18 may be more important than a general intention that the money should be held longer. That does not mean age wording is irrelevant in every trust. It means the wording about age has to be read together with the legal effect of the trust itself. People sometimes focus on the number because it is easy to picture, but the trust structure is what helps determine whether the beneficiary can demand the assets or whether the trustees continue to have a real decision-making role.

Different Trust Types Can Lead to Different Rights

The GOV.UK guidance explains that discretionary trusts are arrangements where trustees can make certain decisions about how to use trust income, and sometimes the capital. Depending on the trust terms, trustees can decide what gets paid out, which beneficiary receives payments, how often payments are made and any conditions to impose. GOV.UK also says discretionary trusts are sometimes set up to put assets aside for a future need, such as a grandchild who may need more financial help than others at some point, or for beneficiaries who are not capable or responsible enough to deal with money themselves.

Other trust types work differently again. GOV.UK says that in an interest in possession trust, the trustee must pass on all trust income to the beneficiary as it arises, while that beneficiary does not have a right to the underlying capital itself. It also describes accumulation trusts, where trustees can accumulate income within the trust and add it to capital, and may also be able to pay income out, as with discretionary trusts. Mixed trusts combine more than one type. The practical lesson is that there is no single model of trusts for children. A child may have a direct right, a right to income only, a possible future benefit at the trustees’ discretion, or rights under more than one trust arrangement within the same will.

Match the Trust to the Family’s Real Aim

Families often use similar language to describe very different intentions. One person may want certainty that a particular child receives a defined share and that trustees are only temporary holders. Another may want trustees to respond flexibly if one child needs more support than another over time. Another may want one beneficiary to receive income first, with children benefiting from capital later. These are not minor drafting variations around the same idea. They point towards different trust structures and different forms of entitlement.

The GOV.UK page on writing a will says that a will should set out who you want to benefit from your will, who should look after any children under 18, who is going to sort out your estate and carry out your wishes after your death, and what happens if the people you want to benefit die before you. It also says you can get advice from a professional if your will is not straightforward, including where you want to leave money or property to a dependant who cannot care for themselves, where several family members may make a claim on your will, or where you have property overseas or a business. Trust wording is often considered precisely because the family’s aims are more detailed than a simple outright gift.

Trustees’ Powers Depend on the Trust Terms

It is easy to assume that once trustees are appointed, they will automatically be able to hold on to assets until they believe a child is mature enough. That is too broad an assumption. Trustees only have the powers given by the trust, and those powers sit alongside the beneficiary’s rights. In a discretionary arrangement, trustees may have genuine scope to decide whether to distribute income or capital and which beneficiary should receive support. In a bare trust, by contrast, the beneficiary’s entitlement is much more direct once the relevant age is reached in England and Wales.

It also helps to keep roles clear. GOV.UK explains that a will should identify who is going to sort out the estate and carry out your wishes after your death, meaning the executor. A will can also create a trust under which trustees hold and manage assets according to its terms. Sometimes the same people may act in both roles, but the functions are still different. For practical planning, that means choosing suitable people involves more than asking who is closest to the family. Reliability, judgement and willingness to follow the terms of the will are all important when a trust is involved.

A Practical Way to Approach Wills With Trusts

A sensible approach is to begin with outcomes rather than assumptions. If the intention is that a child should definitely receive a particular share and adults are simply there to hold it during childhood, one structure may fit better than another. If the intention is to preserve flexibility because children’s needs may change, that may point somewhere else. If the intention is for a beneficiary to receive income first and for children to benefit later, that suggests another route again. The key point is that the beneficiary’s actual entitlement under the trust matters at least as much as the age written into the will.

That is why it can be misleading to speak as if there is an age clause that always prevents access. The GOV.UK material shows that different trust types can operate in materially different ways, and that a bare trust can give a beneficiary in England and Wales the right to capital and income at 18 or over. For anyone considering trusts for children in a will, the practical message is to be clear about the result you want and then make sure the structure chosen is capable of producing that result. Good planning is less about relying on a headline age and more about understanding the rights, powers and limits built into the trust itself.
