Most parents and grandparents want to leave something to the next generation. Handing a large sum to an 18-year-old is not always wise. A trust lets you provide for children or grandchildren while keeping sensible controls in place.
This guide explains the main types of trust used for young beneficiaries, how they work and what they cost, in plain English.
Why Use a Trust for Children
In English law a child under 18 cannot hold property or manage large sums. If your will leaves money directly to a child, trustees hold it until the child turns 18 and then hand over the whole amount.
A trust gives you more control:
- Set the age they inherit: you decide when they are ready (21, 25 or even 30)
- Some protection from outside risks: trust assets are harder for a divorce settlement, a creditor or a failed business to reach
- Support education: trustees can release money for school fees, university or training
- Staged payments: a third at 21, a third at 25 and the rest at 30
- Protect a vulnerable beneficiary: if a child has a disability or additional needs, a trust can provide lifelong support without affecting means-tested benefits
Types of Trust for Children
Comparing Trust Types for Children
| Discretionary Trust | Bare Trust (Simple Trust) | |
|---|---|---|
| Trustees decide when and how to pay out | The child has an absolute right to the assets at 18 | |
| Most flexible; can adapt as circumstances change | Simpler to run and understand | |
| Assets are not automatically part of a beneficiary's estate | Assets are part of the child's estate from 18 | |
| Can cover several beneficiaries (all your children or grandchildren) | Less protection from divorce or money problems | |
| The most common choice for families | Suits smaller amounts |
There are also more specialised options:
18-to-25 trusts: made in a will, these hold assets until the beneficiary reaches an age you choose between 18 and 25. Their inheritance tax treatment is more favourable than a discretionary trust's.
Disabled person's trusts: for a child with a disability. The child is supported without losing means-tested benefits such as Universal Credit.
Life interest trusts: more often used for a spouse, but can give a child an income (rent, for example) while the capital is kept for the next generation.
How to Set Up a Trust for Your Children
The simplest and most common way is through your will. This is called a 'will trust' or 'testamentary trust'. It takes effect only on your death.
Setting Up a Will Trust for Children
- Decide what you want to achieveProtecting the inheritance until they are older, protecting it from divorce, paying for education: your aims shape the type of trust.
- Choose your trusteesPick two or three people you trust completely. They will manage the assets and decide on payments. Consider a mix of family and a professional such as a solicitor.
- Set the termsDecide when the beneficiaries can have the money, whether all at once or in stages, and what it can be used for before then.
- Include it in your willYour solicitor drafts the trust into your will. No separate trust document is needed.
- Write a letter of wishesA non-binding letter explaining your hopes and intentions. It guides the trustees without tying their hands.
Tax on a Children's Trust
Trusts have their own tax rules. Understand them before you set one up.
Inheritance tax: A will trust does not attract extra inheritance tax when it starts; the assets are part of your estate's calculation. A discretionary trust may then face a charge every ten years of up to 6% of its value above the nil-rate band, and exit charges when money leaves.
Income tax: Income kept in a discretionary trust (rent or interest) is taxed at 45%, and dividends at 39.35%. A beneficiary who pays tax at a lower rate can reclaim some of it on income paid out to them.
Capital gains tax: A trust has an annual exemption of £1,500, half the individual allowance (£3,000 where the beneficiary is vulnerable). Gains above that are taxed at 24%.
Family Trust Planning in Bridlington
Many people in Bridlington and East Yorkshire want to leave assets to children or grandchildren but worry about handing everything over at 18. If you are concerned about maturity, marriage or protecting what you have worked for, a trust is often the answer.
Aaron drafts trust provisions in wills and explains every decision clearly. His fees are fixed. A will with a trust in it for one person, a couple's wills with a trust in them, and a lifetime trust for cash, investments or a life policy are each priced on their own. Every fee, with VAT, is on the fees page.
A trust is not about controlling from beyond the grave. It gives your family the best possible start with sensible safeguards.
