Setting Up a Trust for Your Children or Grandchildren

Most parents and grandparents want to leave something to the next generation — but handing a large inheritance directly to an 18-year-old isn't always the wisest move. A trust lets you provide for your children or grandchildren while keeping some sensible controls in place.

This guide explains the main types of trusts used for younger beneficiaries, how they work, and what they cost. We'll keep it in plain English — trusts don't have to be complicated.

Key Takeaways

  • A trust lets you pass on assets while controlling when and how they're received
  • The most common option is a discretionary trust within your Will
  • Trustees (people you choose) manage the trust on your children's behalf
  • You can set age conditions — e.g., inheritance released at 21 or 25
  • Trusts can protect assets from divorce, bankruptcy, and poor financial decisions
  • Setting up a trust through your Will is much simpler than a lifetime trust

Why Use a Trust for Children?

Under English law, children under 18 cannot legally hold property or manage large sums of money. If you leave an inheritance directly to a child in your Will, it gets held by trustees anyway until they turn 18 — at which point they receive the full amount, no questions asked.

A trust gives you more control:

  • Set the age they inherit — you decide when they're mature enough (21, 25, or even 30)
  • Protect from external risks — divorce settlements, creditors, or business failures can't touch trust assets
  • Support education — trustees can release funds for school fees, university, or training
  • Staged distribution — release a third at 21, a third at 25, and the rest at 30
  • Protect vulnerable beneficiaries — if a child has a disability or additional needs, a trust ensures lifelong support without affecting benefits

Types of Trust for Children

Comparing Trust Types for Children

Discretionary Trust
  • Trustees decide when and how to distribute funds
  • Maximum flexibility — can adapt to changing circumstances
  • Assets aren't automatically included in beneficiary's estate
  • Can include multiple beneficiaries (all your children/grandchildren)
  • Most popular choice for families
Bare Trust (Simple Trust)
  • Child has an absolute right to the assets at age 18
  • Simpler to administer and understand
  • Assets form part of the child's estate once they turn 18
  • Less protection from divorce or financial problems
  • Best for smaller amounts or trusted beneficiaries

There are also more specialised options:

18-25 trusts — created in a Will, these hold assets until the beneficiary reaches an age you specify between 18 and 25. They have favourable inheritance tax treatment compared to discretionary trusts.

Disabled person's trusts — designed for children with disabilities. These trusts ensure the child receives support without losing eligibility for means-tested benefits like Personal Independence Payment (PIP) or Universal Credit.

Life interest trusts — more commonly used for spouses, but can be structured to give a child income from assets (like rental income) while preserving the capital for the next generation.

How to Set Up a Trust for Your Children

The simplest and most common way to create a trust for children is through your Will. This is called a "testamentary trust" — it only comes into effect after your death.

Setting Up a Will Trust for Children

  1. 1

    Decide what you want to achieve

    Do you want to protect the inheritance until they're older? Protect it from divorce? Provide for education? Your goals shape the type of trust.

  2. 2

    Choose your trustees

    Pick 2-3 people you trust completely. They'll manage the assets and make distribution decisions. Consider a mix of family members and a professional (like a solicitor).

  3. 3

    Set the terms

    Decide when beneficiaries can access the funds, whether it's all at once or in stages, and what the money can be used for before that age.

  4. 4

    Include it in your Will

    Your solicitor drafts the trust provisions directly into your Will. No separate trust document is needed for testamentary trusts.

  5. 5

    Write a letter of wishes

    A non-binding letter explaining your hopes and intentions. This guides the trustees without restricting their discretion.

Tax Implications of Children's Trusts

Trusts have their own tax rules, and it's important to understand them before setting one up.

Inheritance tax: Testamentary trusts (created in your Will) don't attract additional IHT on creation — they form part of your estate's IHT calculation. However, discretionary trusts may face periodic charges every 10 years (up to 6% of the trust value above the nil-rate band).

Income tax: Trust income (like rental income or interest) is taxed at the trust rate — currently 45% for dividends and 45% for other income. However, beneficiaries can reclaim tax if they're lower-rate taxpayers.

Capital gains tax: Trusts have an annual CGT exemption of half the individual allowance. Any gains above this are taxed at the trust rate (20% for most assets, 24% for residential property).

Frequently Asked Questions

There's no single right answer — it depends on your family. Common ages are 21, 25, or 30. Many parents use staged distributions: a portion at 21, more at 25, and the remainder at 30. This lets children benefit early while protecting the bulk of the inheritance until they're more financially mature.
