Estate Planning: Administration is governed by the Administration of Estates Act 1925 and Wills Act 1837. Professional oversight prevents costly errors.

Including a trust in your will is an established estate planning technique that allows you to control how assets are held and distributed after your death. Trusts in wills - often referred to as testamentary trusts - can protect vulnerable beneficiaries, manage assets for minors, and assist with tax planning while providing flexibility and protection for your legacy. This article explains what a will trust is, why you might include one, the legal framework that applies, types of trusts you can use, the practical steps involved, and common questions people ask when planning a trust in a will. The focus is on legal clarity and practical guidance under the law of England and Wales.

What Is a Trust in a Will?

A trust in a will is a legal arrangement included in your will that comes into effect on your death. Under this arrangement, assets specified in your will are held and managed by one or more trustees for the benefit of named beneficiaries. The trust becomes active only after probate has been granted and your estate begins to be administered. In technical terms, this form of trust is called a testamentary trust.

Unlike a lifetime trust (which you set up while alive), a testamentary trust is created by the wording in your will and only takes legal effect when you die. The trustees you name are responsible for managing trust assets in accordance with your instructions and for the benefit of the beneficiaries you specify.

Why You Might Include a Trust in Your Will

Including a trust in your will allows you to:

  • Protect assets for beneficiaries who are minors or may not be ready to manage an inheritance. Trustees hold and manage the assets until beneficiaries reach a specified age or event.
  • Provide income or use of an asset for a partner or spouse during their lifetime, with the remaining assets passing to other beneficiaries later (a life interest trust).
  • Give trustees discretion over distribution to beneficiaries, which can be useful where financial needs may vary or where flexibility is desired.
  • Plan for inheritance tax more effectively by managing how and when assets are distributed, and in some cases mitigating tax liabilities.

These arrangements are helpful where straightforward gifts under a will might not meet your long‑term intentions or where direct inheritance could expose beneficiaries to risk or misuse of significant assets.

In England and Wales, trusts set up by a will are recognised under established trust law. The trustees you appoint in the will manage trust assets in accordance with their duties under the Trustee Act 2000 and the terms of the trust you set out in the will. Trusts also must comply with formal requirements of the Wills Act 1837 and any relevant tax registration rules, such as registration with HM Revenue & Customs (HMRC) where required.

Under the law, trustees hold legal title to the trust assets and must act prudently, manage those assets responsibly, and act in the beneficiaries' best interests. Trustees may also be responsible for filing tax returns and meeting trust reporting requirements if the trust generates income or has a tax liability.

Common Types of Trusts in Wills

Different types of trusts can be included in a will depending on your objectives and the needs of your beneficiaries. Key types include:

Bare Trusts

A bare trust holds assets on behalf of one beneficiary who has an absolute right to trust assets when they reach a specified age, usually 18 in England and Wales. Trustees hold assets for the beneficiary until that age but otherwise have little discretion.

Life Interest Trusts

A life interest trust (or interest in possession trust) allows someone - often a spouse, partner or other close relative - to benefit from trust assets during their lifetime (for example, by living in a property or receiving income from investments), with the trust capital passing ultimately to other beneficiaries.

Discretionary Trusts

A discretionary trust gives trustees flexibility to decide when and how the trust income or capital is distributed among a group of beneficiaries. This can be useful if beneficiaries' needs are uncertain or change over time.

Each type has different implications for control, taxation and timing of distributions, and professional advice is often necessary to select the right type and draft precise terms.

How to Include a Trust in Your Will

Step 1: Establish Your Estate Planning Goals

Decide why you want a trust in your will. Common reasons include protecting assets for a child or vulnerable relative, providing for a partner's lifetime use of an asset, or distributing assets flexibly among beneficiaries. Clarify these goals before drafting your will.

Step 2: Choose Trustees and Beneficiaries

Select trustees you trust to manage the assets responsibly. Often more than one trustee is appointed to provide checks and balances. Choose beneficiaries clearly and specify the conditions or ages at which they should benefit under the trust.

Step 3: Draft Clear Trust Terms

Work with a solicitor or qualified legal adviser to draft precise wording for the trust in your will. The trust terms should set out:

  • Who the trustees and beneficiaries are.
  • Which assets are to be held in trust.
  • The powers and duties of the trustees.
  • Any conditions or restrictions on distributions.

You may also prepare a letter of wishes to guide trustees on how you would like assets managed and distributed, though such letters are not legally binding.

Step 4: Incorporate Trust Provisions into the Will

Have your solicitor integrate the trust provisions into your will in a way that ensures the trust becomes effective on your death. This requires correct legal wording and compliance with Wills Act formalities, including signature and witnessing.

Step 5: Review and Update as Needed

As your circumstances change (for example, births, deaths or changes in your estate), review your will and trust arrangements. Amendments or updated wills may be necessary to reflect your current intentions.

Registration and Tax Considerations

Many testamentary trusts must be registered with HMRC's Trust Registration Service (TRS) within a stipulated period after your death if they have a tax liability or are new trusts created after recent registration changes. Trustees are responsible for registering the trust and ensuring compliance with reporting requirements.

Tax planning should also be considered. The inclusion of trusts may have implications for inheritance tax, income tax on trust income and capital gains tax. Professional advice helps ensure trusts are effective and tax‑efficient.

Common Questions and Practical Issues

Do Trusts Override the Rest of the Will?

A trust included in a will does not override the will; it forms part of the legal distribution plan. Specific assets placed into trust under your will are administered through the trust structure after death. Proper drafting ensures that trust provisions do not conflict with other parts of the will.

Can Trustees Also Be Beneficiaries?

Yes, a trustee may also be a beneficiary, but it is generally advisable to include at least one trustee who is not a beneficiary to avoid conflicts of interest and ensure impartial administration.

What Happens If a Trust Is Not Properly Drafted?

Poorly drafted trust provisions can lead to administrative difficulties, disputes among beneficiaries, or unintended tax outcomes. Professional legal advice and precise drafting are essential to avoid these risks.

Key Takeaways

Including a trust in your will creates a testamentary trust that governs how certain assets are held and managed after your death. Trusts can provide protection for minors, lifetime benefits for a partner, flexibility for trustees, and potential inheritance tax planning advantages. The process involves:

  • Clarifying estate planning goals.
  • Choosing trustees and beneficiaries.
  • Drafting clear trust terms in your will.
  • Ensuring compliance with legal formalities and tax registration.

Trusts in wills are powerful estate planning tools, but they require careful legal drafting and consideration of tax and administration responsibilities to ensure your intentions are met and beneficiaries are protected.
