Discretionary Trusts (UK)

Flexible estate planning that allows chosen trustees to decide how and when trust assets are used for your beneficiaries.

What is a discretionary trust?

A discretionary trust is a trust in which the trustees have discretion over how and when trust income or capital is distributed among a group of potential beneficiaries, subject to the terms of the trust.

In simple terms, you choose the potential beneficiaries, but the trustees decide who should receive money or assets, when they should receive them and how much should be distributed.

Unlike leaving an inheritance directly to a named beneficiary, a discretionary trust does not necessarily give each potential beneficiary an automatic entitlement to a particular share of the trust fund.

This can provide useful flexibility where you know who you want to benefit but cannot predict their future circumstances.

How does a discretionary trust work?

Assets are held by trustees who manage the trust and exercise their discretion over distributions to eligible beneficiaries in accordance with the trust terms and their legal duties.

The trust document identifies the beneficiaries or classes of people who may benefit and sets out the powers available to the trustees.

STEP 01

Choose the beneficiaries

Define the individuals or groups of people who may benefit from the trust.

STEP 02

Appoint trustees

Choose people who can responsibly manage the assets and make decisions about distributions.

STEP 03

Trustees exercise discretion

Trustees consider the beneficiaries' circumstances and decide when appropriate distributions should be made.

Who owns the assets?

The trustees hold legal title to the trust assets and must administer them in accordance with the terms of the trust and their duties as trustees.

Do I need a discretionary trust?

A discretionary trust may be worth considering when you want several people to potentially benefit from an inheritance but want your trustees to retain flexibility over who receives assets, when they receive them and in what amounts.

They can be particularly useful where future family or financial circumstances are difficult to predict.

You have several beneficiaries

Trustees can consider the circumstances of different beneficiaries rather than dividing everything into fixed shares immediately.

Your beneficiaries are young

You may not want a substantial inheritance passing outright at a particular age.

Future circumstances are uncertain

Flexibility may be useful where you cannot know today which family members will need the greatest support in the future.

You have a blended family

A discretionary structure may provide flexibility where several family members could potentially benefit.

A beneficiary may need additional support

Trustees can consider individual circumstances when deciding whether and how to make distributions.

You want ongoing control and flexibility

Assets can remain under trustee management instead of passing outright immediately.

Who can benefit from a discretionary trust?

A discretionary trust can name individual beneficiaries or define classes of potential beneficiaries, such as children, grandchildren or other family members.

The precise beneficiaries are defined by the trust document.

The trustees can then consider the circumstances of eligible beneficiaries when exercising their powers.

Can a beneficiary demand their inheritance?

A discretionary beneficiary does not normally have an automatic right to demand a particular payment or share simply because they are included within the class of potential beneficiaries.

The trustees must exercise their discretion properly, taking account of the trust terms and their legal duties.

What is a Letter of Wishes?

A Letter of Wishes can give trustees additional guidance about how you would like them to exercise their discretion, although it is generally separate from the legally binding terms of the trust.

For example, you might explain that you would like trustees to consider helping a beneficiary with education, housing or other particular needs.

It can also explain why you chose the trust structure and provide useful context about your family circumstances.

Why this matters: The trust provides the legal framework. A Letter of Wishes can provide your trustees with additional context when exercising the discretion you have given them.

Can I put a discretionary trust in my Will?

Yes. A Will can include a discretionary trust that takes effect after death, allowing specified estate assets to be held by trustees for a defined group of potential beneficiaries.

This can be useful where you want to establish the framework now but allow your trustees to respond to circumstances as they exist after your death.

For example, rather than leaving your estate in fixed percentages to several children, the Will could potentially direct relevant assets into a discretionary trust for a defined group of beneficiaries.

Important: A discretionary trust can involve continuing trustee, administrative and tax responsibilities. It should not be added to a Will simply because it sounds more protective than an outright inheritance.

Discretionary trust vs direct inheritance

IssueDirect InheritanceDiscretionary Trust
Ownership Assets pass directly to the beneficiary. Trustees hold and manage the trust assets.
Fixed entitlement Beneficiary generally receives the inheritance specified for them. Potential beneficiaries do not necessarily have a fixed entitlement to a particular share.
Control Beneficiary controls assets once received. Trustees exercise control subject to the trust terms.
Future flexibility Limited once the inheritance has passed. Trustees may respond to changing beneficiary circumstances.
Administration Generally simpler once the estate is distributed. Ongoing trust administration may be required.

What are the advantages and disadvantages?

The main advantage of a discretionary trust is flexibility. The trade-off is greater complexity, trustee responsibility, administration and potentially different tax treatment compared with an outright inheritance.

Potential advantages

  • Flexibility between beneficiaries.
  • Trustees can respond to changing circumstances.
  • Assets do not have to pass outright immediately.
  • Can provide longer-term management of assets.
  • Useful where future beneficiary needs are uncertain.

Potential disadvantages

  • More complex than an outright inheritance.
  • Trustees have ongoing responsibilities.
  • Trust administration may create additional costs.
  • Separate tax rules can apply.
  • Beneficiaries do not necessarily control when they receive assets.

How are discretionary trusts taxed?

Discretionary trusts have their own tax rules, and inheritance tax, income tax and capital gains tax may all need to be considered depending on the trust, its assets and the transactions involved.

The tax treatment of trusts can differ significantly from assets owned personally or inherited outright.

Tax rules and allowances can also change, so the consequences should be considered using the legislation and rates applying at the relevant time.

Tax advice: A discretionary trust should not be established on the assumption that it will automatically reduce inheritance tax or provide another tax advantage. Specialist tax advice may be appropriate depending on the assets and circumstances involved.

Frequently Asked Questions About Discretionary Trusts

Who controls a discretionary trust?

The trustees manage the trust assets and exercise the powers given to them by the trust document, subject to their legal duties.

Can a beneficiary demand money from a discretionary trust?

A discretionary beneficiary does not normally have an automatic right to demand a particular distribution. Decisions about distributions are made by the trustees in accordance with the trust terms and their duties.

Can trustees give everything to one beneficiary?

This depends on the powers and terms of the particular trust. Trustees must exercise their discretion properly and consider relevant beneficiaries rather than acting arbitrarily.

Can my children be beneficiaries?

Yes, children can potentially be included within the class of beneficiaries, along with other individuals or groups specified by the trust.

Can I include future grandchildren?

A trust can potentially define beneficiaries by class, which may allow future family members to fall within the beneficiary group depending on the drafting.

How long can a discretionary trust last?

The duration depends on the trust terms and the legal rules applying to the particular trust. The intended duration should be considered when the trust is drafted.

Is a discretionary trust right for everyone?

No. Many people are better served by a straightforward Will and direct inheritance. A discretionary trust is more likely to be relevant where flexibility, ongoing management or complex beneficiary circumstances justify the additional administration.
